Air conditioners with a heating function – which device to choose?

The choice of an air conditioner with a heating function depends on many factors, such as energy efficiency, quiet operation, and additional features. Models such as Daikin Stylish White and Gree Amber Prestige offer the latest technologies and exceptional performance, while others, such as LG DUALCOOL STANDARD and Fujitsu KMCC, stand out for their energy efficiency and functionality. The decision should be based on individual needs, but each of these models will provide comfort throughout the year, combining cooling and heating in one device.

Air conditioning at home or in the office is extremely convenient, especially on hot days. However, even the best-chosen equipment can cause problems – water may start dripping from the unit or an unpleasant odor may emanate from it. For many people, this is a sign that the device needs to be replaced, but in most cases, these faults can be dealt with without drastic measures. Find out what the causes may be and how to deal with them.

Where does the water in the air conditioner come from?

If you notice that your air conditioner is starting to drip, the first step is to understand where the water in such a device comes from. An air conditioner cools the air and dehumidifies it at the same time. This process produces condensate, i.e., liquefied water vapor. Normally, this water flows down a special drain pipe and is discharged outside the building or into the sewage system. The problem starts when this system stops working properly.

The most common cause is a clogged drain. Sometimes dust, insect remains, and even mold accumulate in the pipe. As a result, the water has nowhere to drain and begins to collect in the tray under the evaporator, and then overflows outside the unit. Sometimes the fault lies with a leak in the system or a damaged component responsible for draining the condensate.

One more thing should not be forgotten – incorrect installation. If the indoor unit has not been mounted in a perfectly horizontal position, water may accumulate in the wrong place and, instead of flowing through the pipe, it will leak into the room. Therefore, it is important to ensure professional installation and, in case of problems, check the mounting level.

What to do when your air conditioner is leaking?

The first thing you can do yourself is to check the drain pipe. If it is easily accessible, simply blow it out gently or rinse it with pressurized water. Many people use a syringe or a small pump for this purpose. If debris has accumulated in the pipe, the problem should disappear.

The next step is to clean the condensate tray. Simply disconnect the device from the power supply, open the housing, and thoroughly clean all components where water may have accumulated. A soft cloth and mild detergent work well for this purpose. It is not recommended to use strong chemicals that can damage delicate plastic components.

If the problem recurs, it is worth checking whether the drain pipe has been damaged or broken. Sometimes a simple bend can prevent water from draining freely. If the device was installed a long time ago, it is also possible that the seals have worn out and need to be replaced.

If all these simple measures prove ineffective, it may be necessary to call in a professional. A service technician will not only check the drain pipe for blockages, but also assess whether the problem lies in the design of the device itself. This will help you avoid flooding your walls, floors, or furniture and save you additional repair costs.

Why does the air conditioner smell bad?

An unpleasant smell coming from the air conditioner is a signal that absolutely cannot be ignored. The most common causes are contamination and the growth of microorganisms inside the device. Filters and heat exchangers accumulate dust, pollen, and moisture, which create an ideal environment for mold and bacteria to grow. When you turn on the air conditioner, air flows through the contaminated components and spreads the unpleasant odor throughout the room.

Sometimes the cause is also a blocked drain, as mentioned earlier. Standing water becomes a place where microorganisms multiply. A musty or damp smell is a typical symptom of this problem.

We mustn’t forget about the smell of burning. If it appears when the air conditioner is running, it may indicate electrical problems, worn cables, or an overheating fan motor. In this case, it is not worth delaying, but calling a specialist immediately, as the fault may be dangerous.

How to get rid of unpleasant odors from your air conditioner?

The most effective way is regular cleaning and maintenance. Air filters should be washed at least once every few weeks during the summer season. Simply remove them, rinse them under running water, and then dry them. Clean filters not only eliminate unpleasant odors, but also improve the air quality in the room.

It is also a good idea to descale the device from time to time. This can be done with special spray preparations that destroy bacteria and fungi inside the unit. Spray the preparation onto the evaporator and into the ducts, then start the device so that the agent can spread throughout the system. These types of measures are simple and relatively inexpensive, and can significantly improve user comfort.

Professional service companies offer more advanced methods, such as ozone treatment or chemical cleaning. This is a good solution if the air conditioner has not been used for a long time or if the problem recurs despite regular maintenance of the device. Ozone effectively neutralizes unpleasant odors and eliminates microorganisms, while specialized chemicals remove even hard-to-see mold spots.

In addition to the device itself, it is also worth remembering about ventilation ducts if the air conditioning is integrated with the ventilation system. Contaminated ducts can be a source of odors that cannot be eliminated by cleaning the indoor unit alone. Regular inspections of the entire installation will help you avoid such surprises.

Historic buildings have attracted attention for centuries with their history, architecture, and aura. However, modern people expect not only aesthetic impressions, but also comfort. On hot days, it is difficult to imagine long church services, concerts, or performances in stuffy interiors, which is why the question of how to combine tradition with modernity is being asked more and more often. Installing air conditioning in places that were built hundreds of years ago is a task that requires sensitivity, knowledge, and enormous responsibility.

A delicate balance between history and technology

Historic churches and theaters are not just walls. They are testimonies to eras, evidence of the craftsmanship of former masters, and places where the identity of local communities has been shaped over centuries. Introducing modern installations into them is always a balancing act — between the need to provide people with comfort and preserving the authenticity and character of the space.

Architects and engineers must be fully aware that even the smallest mistake can not only compromise the aesthetics of the interior, but also threaten the stability of the structure. Elements such as frescoes, carved altars, gilded cornices, and delicate stucco react to changes in temperature and humidity. Excessive cooling could lead to microcracks, paint peeling, or plaster crumbling.

In many cases, conservators also pay attention to spiritual or artistic aspects. A church is not just a hall, and a theater is not just a functional building. These are places where atmosphere and acoustics are of great importance. Therefore, air conditioning must not generate noise that disturbs the silence of prayer or noise that detracts from the pleasure of listening to an orchestra. This often means investing in the quietest solutions available, which operate subtly, almost imperceptibly.

The balance between history and technology is, in practice, a constant game of compromise. Designers know that discretion is paramount in such projects — the technology should be present, but invisible and inaudible, so as not to overshadow what makes a place unique.

Designing tailor-made systems

There is no single universal solution that will work in every historic building. What can be used in a modern office building is often impossible to implement in a theater that is two centuries old. There is no room for standard schemes here—each project becomes a separate case study.

Discreet solutions are often chosen: air ducts hidden in existing structures, cooling units concealed in boxes or under galleries, and even systems that use natural ventilation. In some churches, for example, air vents styled as decorative elements are used, making them almost part of the decor.

Installation is often preceded by months of consultation with conservators, who ensure that the intervention is as inconspicuous as possible. Sometimes designers have to change their initial concepts to adapt them to the requirements of monument protection. In practice, this often means creating innovative systems that have not been used on such a scale before.

An example of this are microclimate-based installations that allow only selected areas to be cooled, such as the section for worshippers in a church or the stalls in a theater. This means that the installation does not have to cover the entire building, while still achieving the desired effect. This approach is similar to tailoring a suit. Each element must fit perfectly and be adapted to the proportions and character of the place.

The result of a well-designed system is an installation that no one will notice at first glance, but which has a real impact on user comfort. This proves that technology does not have to destroy harmony if it is introduced with the right sensitivity.

Cooperation between experts in various fields

Installing air conditioning in historic interiors is not just a technical task. It is a process involving a whole team of specialists: engineers, architects, acousticians, art historians, as well as clergy or directors of cultural institutions. Each of them looks at the project from a different perspective and has different priorities.

For the conservator, the most important thing is to preserve the original structure and protect it from degradation. For the theater director, it is to ensure the comfort of the audience, which will increase attendance and the prestige of events. For a clergyman, it is maintaining the sacred character of the space. For an engineer, it is finding a solution that will work reliably for years without placing excessive strain on the building’s structure.

There are often heated discussions in which different visions clash. However, it is precisely this diversity of opinion that leads to the best solutions. Cooperation requires not only knowledge, but also patience. Sometimes a single project goes through a dozen or so versions before it is accepted by all parties.

It is worth noting that the installation of air conditioning in such a facility does not end at the installation stage. Maintenance and regular servicing of the system are also important. The service staff must be aware that a minor failure or excessive use can negatively affect the condition of the monument. This makes staff training and the development of operating procedures as important as the installation itself. Shared responsibility thus becomes the key to the success and longevity of the system.

The art of compromise and long-term effects

Looking at the process of installing air conditioning in historic churches and theaters, it is easy to see that this is not just a technical issue. It is a true art of compromise, where history and the present meet. On the one hand, there is a need to protect cultural heritage, and on the other, a need to meet the expectations of contemporary audiences.

With the right solutions, you can not only ensure comfort, but also protect works of art. Stable temperature and humidity conditions guarantee that paintings, sculptures, and decorative elements will survive for centuries to come. In this way, air conditioning becomes not so much a modern convenience as a conservation tool that supports the protection of cultural assets.

The social aspect is also important. People are more likely to participate in events if they feel comfortable. A stuffy interior in the middle of summer can discourage even the most ardent art lovers. Properly designed air conditioning makes a theater or church an open and visitor-friendly place.

The installation of air conditioning in historic spaces can therefore be treated as a challenge, but also as a form of art — requiring subtlety, imagination, and respect for the past. Every successful project proves that technological development and care for heritage can go hand in hand, as long as knowledge is combined with passion. This, in turn, gives hope that future generations will be able to experience the beauty of historic interiors in conditions that are conducive not only to contemplation but also to comfort.

In summer, air conditioning can save the day, but it can also quickly strain your household budget. High temperatures mean that we turn it on more often and for longer periods of time, and the electricity bill can then come as a surprise. However, this does not mean that you have to choose between comfort and savings. There are many ways to enjoy the cool air without paying a fortune for energy. All you need to do is combine the right choice of equipment, the right settings, good habits, and regular maintenance.

Choosing the right device is half the success

A well-chosen air conditioner is an investment that pays for itself in your bills. If the device is too weak, it will run continuously, trying to maintain the set temperature, which will translate into higher electricity consumption and faster wear and tear of parts. On the other hand, a model that is too powerful will cool too quickly, then turn off and restart, which also generates additional costs and shortens the life of the compressor.

To avoid these problems, it is worth calculating the cooling capacity requirement, taking into account the floor space, room height, number of people, sunlight exposure, and the number of heat-emitting devices (e.g., computers or televisions). For a standard room with a height of 2.5 m, an average of approximately 100 W of cooling capacity per square meter is assumed, but if the room is sunny or has large windows, the demand may increase by up to a third.

Modern inverter air conditioners are more energy-efficient because they smoothly adjust the compressor power to the current demand. As a result, they consume less energy than models operating in “on/off” mode. Additional features such as presence sensors, automatic airflow control, and energy-saving modes can further reduce operating costs.

Settings that matter

Even the best equipment will be expensive to maintain if used inefficiently. One of the most common mistakes is setting the temperature too low. A sudden difference between the indoor and outdoor temperatures is not only unhealthy for the body, but also requires the air conditioner to work harder. It is recommended that this difference be around 5-7°C. If it is 33°C outside, setting the temperature to 26-27°C is enough to achieve a comfortable feeling.

Another thing is to use ECO or night modes. ECO mode limits the power of the compressor and adjusts the airflow to maintain comfort in an energy-efficient way. Night mode works similarly, gradually raising the temperature during sleep when the body naturally needs less cooling.

It is also important to set the airflow direction. An upward airflow allows for even distribution of cool air throughout the room without creating unpleasant cold drafts. In many models, you can program the blinds to oscillate automatically for even more effective air distribution.

Air conditioning and your home

The efficiency of an air conditioner depends largely on the conditions in the building. If the rooms are very sunny, the device will have to work harder. Therefore, one of the simplest and cheapest ways to reduce the load on the air conditioning is to use window coverings — roller blinds, shutters, awnings, or curtains. Closing them during the hottest hours of the day can lower the temperature in the room by up to several degrees.

Another issue is the airtightness of rooms. If windows or balcony doors are not airtight, hot air will enter the room, forcing the air conditioner to work harder. Simple DIY seals can reduce this problem and lower energy consumption.

It is also important to remember to avoid ventilating the room while the air conditioner is running. If you want to let in fresh air, it is best to do so early in the morning or late in the evening when the outside temperature is lower. In addition, you can support the air conditioning with a ceiling or standing fan — this will distribute the cool air more quickly and allow the unit to operate at a lower power setting.

Maintenance and service — invisible savings

Even a modern air conditioner will consume more energy if it is dirty or poorly adjusted. The most common problem is clogged filters, which restrict air flow. This forces the compressor to work harder, which means higher electricity consumption and a greater risk of failure.

Filters should be cleaned regularly, preferably every two to four weeks during periods of intensive use. Usually, it is enough to remove them and rinse them under running water or vacuum them. For replaceable filters, follow the manufacturer’s recommendations for replacement frequency.

It is worth ordering a professional service once a year. A specialist will check the tightness of the system, refill the refrigerant, clean the evaporator and condenser, and check the condition of the compressor. These activities often prevent situations in which the device loses efficiency and consumes more energy, and bills start to rise.

Taking care of your air conditioner not only reduces costs, but also improves the air quality in your home. Clean filters are more effective at trapping dust, pollen, and pollutants, which translates into greater comfort for your household, especially for those with allergies.

Studio apartments are becoming increasingly popular, especially among young people and those who appreciate open space and modern design. The lack of partition walls makes the interior seem larger and brighter, and the layout gives more room for creativity. At the same time, this layout poses challenges when it comes to maintaining adequate air quality. All areas—the kitchen, living room, and bedroom—are located in one room, which means that every smell and every change in humidity affects the whole space. If we do not ensure proper air exchange, the apartment will quickly feel stuffy, and in extreme cases, there will be problems with moisture and mold.

Why ventilation in a studio apartment is more difficult than in a traditional layout

In apartments with a classic room layout, air can be directed independently to each room. Doors are a natural barrier to odors and moisture, and often each room has its own ventilation duct. In a studio apartment, the situation is different — the entire interior is one space, so air circulation is less controlled. If we cook dinner, the aromas travel directly to the sleeping area. If we take a hot shower, the steam goes into the living room and settles on cooler surfaces such as windows or walls.

It should also be remembered that most new residential buildings are very airtight. Good window and door seals save energy, but at the same time restrict the natural flow of air. In the past, micro-gaps in window frames or leaky entrance doors allowed for a constant, albeit uncontrolled, exchange of air. Now, if there is no additional mechanical ventilation system in the studio, the air simply stays in place. This, in turn, means higher carbon dioxide concentrations, unpleasant odors, and a feeling of a “heavy” atmosphere.

The most common problems associated with a lack of proper ventilation

The first and most troublesome problem is odors. In a studio apartment, the kitchen is usually part of the living room, so frying, cooking, or even making popcorn in the microwave immediately fills the entire apartment. If the ventilation is not working efficiently, the odors linger for hours and permeate textiles — curtains, bedding, clothes.

The second problem is excessive moisture. The bathroom in a studio apartment often has no window, and if the fan is weak or rarely used, the steam from bathing spreads throughout the entire apartment. Combined with cooler surfaces, such as wall corners or winter windows, this leads to water condensation and, as a result, mold growth. This is not only a matter of aesthetics, but also of health — mold can cause allergies, breathing problems, and other ailments.

  The third issue is air quality in terms of oxygen and carbon dioxide content. In a small apartment with a single space, CO₂ concentration rises faster, especially at night when the windows are closed. This manifests itself in drowsiness, decreased concentration, and even headaches. Combined with a lack of ventilation, this can significantly reduce the quality of life.

Solutions to improve air quality in a studio apartment

One of the best solutions is to install mechanical ventilation with heat recovery. In large houses, this means an extensive ductwork installation, but in studio apartments, small wall-mounted recuperators can be used. The device is installed in the outer wall and works by exchanging air—fresh air from outside enters the interior, while stale air is removed—while simultaneously recovering thermal energy. This allows the apartment to be ventilated even in winter without heat loss.

If recuperation is not an option, it is worth strengthening the existing gravity ventilation. A fan with a humidity sensor or delayed shut-off, which continues to operate for a few minutes after bathing, will work well in the bathroom. In the kitchen, the best choice is a hood connected to an exhaust duct — models with a carbon filter in recirculation mode only mask odors, but do not remove them.

Window vents, which supply fresh air from outside, are a good addition. Combined with exhaust ventilation, they ensure a constant supply of oxygen and reduce humidity. In small apartments, such a simple system can dramatically improve comfort without high costs.

Everyday tips for maintaining good air circulation

Even the best installation requires some discipline from the household members. In a studio apartment, it is worth ventilating the apartment briefly but intensively — by opening windows on opposite sides of the building (if possible) and creating a draft. Such ventilation takes only a few minutes, but effectively exchanges air without significantly cooling the interior.

When cooking, turn on the hood immediately before odors have a chance to spread. In the bathroom, close the door while bathing and use a fan. Clean the filters in the hood and ventilation devices once a month, as accumulated grease and dust not only reduce efficiency but can also cause unpleasant odors.

It is a good idea to monitor the humidity of the air with a simple hygrometer. If it remains above 60%, increase the intensity of ventilation or consider purchasing a dehumidifier. During the heating season, when the air tends to be dry, you can use a humidifier, but always in combination with good circulation to prevent mold growth.

In a studio apartment, minor negligence in ventilation quickly becomes apparent. Therefore, it is better to take preventive measures—by adopting daily habits and taking care of the technical elements of the system—than to deal with unpleasant consequences later on.

For many, a summer holiday in a holiday home is a true oasis of peace, a respite from the hustle and bustle of the city and the daily rush. However, during hot days, high temperatures can effectively spoil the comfort, causing fatigue, sleep problems and general malaise. When considering cooling solutions, it is worth thinking carefully about how to use air conditioning effectively and economically, so that you can enjoy a cool interior only when you really need it. In holiday homes, it is particularly important to choose a system that is suited to seasonal use and to consider natural ways of limiting the heating of rooms.

Stationary air conditioning — efficiency and comfort in the summer season

In summer houses, which are mainly used during the summer season, the best and most effective solution is to choose a split or multi-split stationary air conditioning system. These systems consist of two main units — an external unit, which removes heat outside, and an internal unit, which cools the air in the room. Thanks to this design, stationary air conditioners are characterised by high cooling efficiency and low noise levels inside, which significantly increases the comfort of use.

The installation of a split system may require a slightly higher investment, especially if the summer house was not prepared for this type of equipment. However, this investment pays for itself through the long service life of the equipment and savings resulting from lower energy consumption compared to portable air conditioners. Multi-split systems, which allow several rooms to be served from a single outdoor unit, further increase flexibility of use. The ability to individually control the temperature in different parts of the cottage allows cooling to be limited only to the areas where we are present, which translates into lower operating costs.

Thanks to the stable and even operation of stationary air conditioning, you can count on significantly higher thermal comfort than when using portable devices. They are also more durable and easier to maintain in the long term, which is important for seasonal use. The ability to secure and shut down the system during the off-season further protects the equipment from damage and wear.

Portable air conditioners — an alternative, but not without drawbacks

There are many portable air conditioners on the market that are tempting due to their ease of installation and mobility. They may seem like a convenient solution in summer houses, especially when the installation of a stationary system is difficult or impossible. However, it is worth approaching them with caution, as their efficiency and comfort of use often leave much to be desired.

Portable air conditioners require a pipe to be installed to remove warm air to the outside, which often causes leaks around windows and thus the escape of cooled air. For this reason, cooling the room can be less effective, and the device works harder, consuming more energy. In addition, portable models are usually louder than split air conditioners, which can disturb peace and rest.

It is also worth remembering that portable devices have limited power and are best suited for small rooms or as a temporary solution. They are not suitable for long-term and comfortable cooling of an entire summer cottage. For this reason, it is best to treat them as an emergency alternative or supplement to stationary air conditioning, rather than as the main cooling system.

Using architecture and the environment to combat heat

Natural methods of reducing the heating of a cottage can significantly reduce the need for air conditioning and lower operating costs. A well-thought-out design and proper use of the environment are the foundation of effective cooling.

Shading windows is one of the simplest and most effective ways to reduce interior heating. Installing external roller blinds, façade blinds or awnings can reduce the amount of sunlight reaching the windows by up to several dozen percent. This keeps rooms cooler for longer, and the air conditioner does not have to run at full capacity.

The vegetation around the house plays a double role — it provides shade and cools the air through transpiration. Planting deciduous trees on the south side of the building or using climbing plants on the facades are natural sun barriers that not only improve thermal comfort but also enhance the aesthetic value of the property.

Natural ventilation is also important — airing the house at night allows heated air to be replaced with cooler air from outside. Creating draughts by opening windows and doors appropriately allows the interior to be cooled effectively without using energy. In addition, light-coloured facades and roofs reflect the sun’s rays, preventing the walls and attic from heating up. Well-executed thermal insulation and airtightness of the building help to keep the coolness inside and protect against excessive heating.

Optimal use of air conditioning — comfort and cost savings

The key to cheap and effective cooling is not only choosing the right system, but also using it consciously and sensibly. The optimal temperature to set your air conditioner to is around 24-25 degrees Celsius. This allows you to maintain a comfortable indoor climate while preventing excessive energy consumption, which occurs when the settings are too low.

Modern stationary air conditioners offer many energy-efficient features, such as automatic modes, timers and night modes. These allow the device to adjust its operation to current needs, minimising unnecessary power consumption. It is worth taking advantage of these features and setting the air conditioner to operate only when necessary.

Regular maintenance of the system — primarily cleaning and replacing filters — is essential to maintain its high performance. Dirty filters force the device to work harder, which increases energy consumption and shortens the life of the equipment. During the summer season, well-planned service inspections will help avoid breakdowns and ensure stable operation throughout the entire service life.

For those looking for additional savings, the installation of photovoltaic panels is an increasingly popular solution. In summer, when energy consumption for cooling is at its highest, the panels generate the most electricity, which can power the air conditioning, significantly reducing operating costs and reducing the user’s carbon footprint.

Libraries and archives are not only repositories of knowledge, but also true treasure troves of history and culture, often storing unique and highly sensitive materials. In order for these resources to survive for decades or even centuries, they must be stored under strictly controlled environmental conditions. Ventilation is one of the most important elements of the system for protecting these valuable collections, as it is responsible for air quality, humidity and temperature, which directly affect the condition of stored documents and books. In this article, we will look at the challenges posed by ventilation in libraries and archives, the solutions available, and the latest technologies that can effectively protect these valuable collections from damage.

Environmental challenges in libraries and archives

Storage of books and documents in libraries and archives is a real challenge due to their sensitivity to environmental conditions. Air humidity is one of the most important factors — if it is too high, it leads to the growth of mould and fungi, which are extremely destructive to paper. Mould can spread over large areas, attacking not only documents, but also bindings and bookbinding materials. On the other hand, too low humidity makes paper brittle and prone to breaking, and also accelerates the ageing process of materials. The optimal humidity range in such places is usually between 45 and 55 per cent, and maintaining it at a constant level requires precise control. Temperature also plays a significant role — too high a temperature promotes the chemical decomposition of paper and dyes, while too low a temperature can cause cracking and deformation of materials. It is best to maintain a temperature of around 18-22°C, with minimal fluctuations. In addition, the air in such rooms must not be contaminated with dust, dirt or chemical gases, which can accelerate the degradation of materials. In municipal libraries, where the outside air is often polluted with nitrogen or sulphur oxides, ventilation must additionally filter these harmful substances. All this means that ventilation in such facilities requires not only effective air exchange, but also maintaining the highest air quality and stable parameters throughout the year.

Ventilation systems adapted to the specific nature of the collections

The design of ventilation in libraries and archives requires an individual approach that takes into account the nature of the stored materials and the specific characteristics of the building. Ventilation must ensure gentle and continuous air exchange, eliminating the risk of draughts that can mechanically damage delicate books or documents. In practice, mechanical ventilation with precise parameter control is most commonly used. These systems are equipped with high-efficiency filters, such as HEPA filters, which remove dust, dirt and other solid particles, and chemical filters, which eliminate harmful gaseous compounds. In addition, there are air humidification and dehumidification systems that maintain humidity at 45-55%. Advanced systems can also be equipped with heat recovery, which not only maintains a stable temperature but also reduces operating costs. In modern facilities, ventilation is often integrated with building automation systems, which use humidity, temperature and air quality sensors to monitor conditions and automatically adjust the system’s operation. Such solutions help to avoid sudden changes in conditions that could damage the collections and reduce the risk of failure. It should also be remembered that the ventilation system must be regularly serviced and maintained to ensure its reliability and continuity of operation, which is absolutely essential for the safety of archival materials.

Preventing risks through proper ventilation

Effective ventilation is one of the most effective protective barriers against many risks to books and documents. First and foremost, continuous and well-designed air exchange prevents moisture and condensation from forming on the surfaces of walls, shelves or the materials themselves. Condensation can lead to stains, mould growth and accelerate paper decomposition, which is why its elimination is so important. In addition, ventilation helps to maintain an optimal humidity level, which prevents paper from drying out and crumbling, and also reduces the possibility of corrosion on metal binding elements or archival equipment.

Purifying the air of dust and other pollutants protects the collection from harmful particles that could cause mechanical damage. Ventilation also affects the health and comfort of library and archive users by eliminating unpleasant odours and harmful microorganisms that can develop in enclosed spaces. All this makes an adequate ventilation system indispensable for both the protection of collections and the people who work with them on a daily basis.

Modern technologies and the future of ventilation in libraries and archives

Ventilation technologies in libraries and archives are constantly evolving, becoming increasingly intelligent and efficient. Today, many systems are equipped with a network of sensors that monitor temperature, humidity and air composition in real time. This data is sent to building management systems, which automatically adjust ventilation parameters to maintain ideal conditions with minimal energy consumption. Increasingly, artificial intelligence-based solutions are being introduced that can predict changes in environmental conditions and prevent potential threats before they arise.

Integrating ventilation with other systems, such as air conditioning or heating, allows for the creation of a balanced microclimate that is beneficial for both crops and people. In addition, there is a strong focus on green technologies that reduce the carbon footprint of such installations. In the future, we can expect increasingly advanced solutions that will not only protect cultural heritage, but also fully exploit the capabilities of modern automation and data analytics, ensuring the longevity and safety of priceless materials.

Restaurants with open kitchens are gaining popularity because they allow guests to interact directly with the food preparation process, which builds a unique atmosphere and transparency. However, such a solution poses significant ventilation challenges for owners and designers. Odors, moisture, steam and heat must be effectively controlled so as not to interfere with the comfort of customers or staff. It’s worth thinking carefully about the design of the ventilation system to create a space that is welcoming and hygienic for both guests and cooks. In this article we suggest what to pay attention to when planning ventilation in a restaurant with an open kitchen. This issue is often overlooked, and a well-functioning ventilation system can significantly increase the prestige of the premises. Air comfort also influences customers’ decision whether they will return to the restaurant. Well-maintained ventilation also means less risk of problems with health and fire inspections.

Open kitchen characteristics and ventilation challenges

Open kitchens allow culinary artistry to be showcased and create a unique atmosphere, but require a special approach to air exchange. Unlike traditional venues, where the kitchen is enclosed and separated from the room, here steam, odors and heat have an easier path to the guest space. Without proper ventilation solutions, this can lead to discomfort and even hygiene problems. Already at the design stage, it’s worth considering how to design a system that will efficiently exhaust vapors and moisture without letting them spread throughout the premises. This requires precise selection of fans, hoods and vents so that the air circulates in a controlled manner and the hospitality area remains fresh and pleasant. In addition, you need to take into account the specifics of the location – a restaurant on the ground or first floor may require different solutions due to the natural flow of air. Also, do not forget about seasonal changes in temperature and humidity, which affect the effectiveness of ventilation and the comfort of the occupants.

Choosing a ventilation system to meet restaurant specific needs

The choice of ventilation system must correspond to the size of the establishment, the intensity of the kitchen and the nature of the food offered. For example, restaurants with a lot of frying and grilling require more powerful exhaust systems to effectively remove greasy fumes and odors. Kitchen hoods should have sufficient capacity to prevent grease from settling on walls and equipment, making it difficult to maintain cleanliness. The supply system, on the other hand, must provide fresh air at a rate balanced with the exhaust to avoid negative pressure and uncontrolled drafts. A well-designed system also takes into account the possibility of heat recovery and automatic adjustment of ventilation intensity to the current conditions in the restaurant. This translates into energy savings and better thermal comfort for guests and employees. In addition, modern solutions can offer remote control and monitoring of the system’s operation, making it easier to manage and quickly respond to any problems.

Ventilation noise and the comfort of guests and employees

Ventilation should work efficiently, but also not interfere with conversations or the work of cooks. Noise generated by fans and ventilation ducts can be very disruptive, especially in premises where the emphasis is on an intimate atmosphere. Therefore, when designing the system, it is worth paying attention to the selection of equipment with low noise levels and the use of acoustic dampers and soundproofing materials. Speed-controlled fans allow you to adjust the intensity of operation to the needs of the premises, which helps reduce noise during lower occupancy. In addition, proper air distribution helps avoid unpleasant drafts and uneven cooling or heating, which increases the comfort of everyone in the restaurant. Aesthetics should not be forgotten either – ventilation elements should be discreet and blend in with the interior so as not to spoil the aesthetic experience. Well-designed ventilation can even emphasize the design of the interior, if the devices are properly hidden or are an interesting design element.

Maintenance and service of ventilation – what do you need to remember?

A ventilation system is an investment that requires regular care. Where the air is full of grease and fumes, filters and ducts quickly become dirty, which reduces the effectiveness of ventilation and can lead to more serious failures. Regular cleaning of filters and ducts helps maintain high air quality and prevents the growth of bacteria or mold. It’s also an important safety precaution, as grease buildup can be the cause of a fire. Scheduling ventilation service and inspections is a way to avoid unexpected problems and keep your premises in perfect condition for many years. In addition, an efficient system uses less energy, which translates into lower bills and a lower environmental impact. So it’s worthwhile to set a maintenance schedule in advance and choose a company that will professionally take care of the ventilation throughout the restaurant’s operation. It is also important to remember to educate the staff on the operation and basic maintenance of the equipment, allowing them to react quickly to the first signs of failure.

Choosing the right refrigerant for air conditioning is a topic that is coming up more and more often in conversations among both installation companies and individual customers. It is not only a question of cooling efficiency and comfort, but also an increasingly important environmental and safety aspect. R32, R410A and R290 are the substances that dominate the market, although they differ in many respects. Understanding their properties will help you make an informed decision that will translate into lower bills, better system performance and less environmental impact. In this article, we will take a closer look at each of these refrigerants – how they work, their advantages and limitations, and in which situations they will work best.

What are refrigerants and why do they matter?

Refrigerant is the heart of any air conditioning unit – without it, there would be no way to effectively cool the air. The substance circulates in a closed loop, changing its state of aggregation from liquid to gas and vice versa, allowing it to take heat from one place and give it away in another. This makes the room pleasantly cool, even when it’s hot outside.

In the history of refrigeration and air conditioning, refrigerants have undergone a huge evolution. The first popular CFCs (CFCs) were very effective, but unfortunately, years later their destructive effects on the ozone layer were discovered, sparking global action to restrict their use. Later came HFCs, such as R410A, which, while not destructive to the ozone, have a very high global warming potential. Today, increasing attention is being paid to lower climate impact refrigerants, such as R32 and R290, which combine efficiency with less harm.

In practice, the choice of refrigerant affects not only comfort and operating costs, but also legal issues and installation and service requirements. Not every refrigerant is suitable for every type of air conditioner, and not every service company is qualified to work with each one.

R32 – a modern and more eco-friendly choice

R32 is one of the newest refrigerants that is gaining popularity in modern air conditioners. Its biggest advantage is its lower GWP, which is about 675, meaning it has a much lower greenhouse effect compared to many older substances. This is an important consideration for individuals and companies that want to reduce their environmental impact while still using efficient air conditioning.

At the same time, R32 is very efficient at transferring heat, allowing equipment to achieve high efficiency with lower energy consumption. This translates into lower electricity bills, as well as lower carbon emissions associated with energy production. In addition, R32 requires less refrigerant to fill the unit, further reducing operating costs and the risk of potential leaks. It is worth remembering, however, that R32 is flammable (albeit with a low flammability rating), which places certain requirements on installers and service technicians. In practice, this means that air-conditioning installation and repair work on this refrigerant should be carried out by certified specialists who follow strict safety standards. Nevertheless, its advantages mean that R32 is considered the future choice and is increasingly replacing older substances in new equipment.

R410A – proven but increasingly unpopular

R410A is a mixture of two gases – R32 and R125 – which for many years was the standard in air conditioning. Thanks to its good thermodynamic properties, it provides high cooling efficiency and is non-flammable, which made it easier to install and operate equipment.

Despite its advantages, R410A has a very high GWP (about 2088), which means that its release into the atmosphere contributes significantly to global warming. In response to growing environmental concerns, many countries around the world are restricting or banning the use of this refrigerant in new installations. Therefore, manufacturers of air conditioning equipment are increasingly moving away from R410A and offering equipment that runs on more environmentally friendly substances.

Technically, R410A operates at high pressure, which requires a more robust design of equipment and can affect its durability. Servicing air conditioners with this refrigerant is usually more expensive and requires specialized equipment. For many users, this is important information, because not only the purchase price, but also the subsequent repair and operating costs are of great importance.

Although R410A is still on the market, its days are slowly coming to an end, and legal changes and environmental requirements mean that it will be used less and less in the coming years.

R290 – natural and environmentally friendly, but requires caution

R290 is nothing more than propane – a natural, environmentally friendly refrigerant that is gaining interest especially where environmental aspects and energy efficiency are important. Propane has a very low GWP (about 3), making it one of the best choices from a climate protection perspective.

In addition to being environmentally friendly, R290 has excellent cooling properties, so equipment running with it uses less energy than models on older refrigerants. This means lower electricity bills and less impact on the environment. In addition, propane is cheap and widely available.

However, the natural flammability of R290 places high safety requirements. Equipment must meet stringent standards, and installations must be performed by qualified professionals. Installing and servicing propane systems requires adequate knowledge and tools to minimize the risk of fire. That’s why R290 is more popular in smaller portable air conditioners or specialized refrigeration systems than in large central systems.

Despite these challenges, the naturalness and efficiency make R290 increasingly popular, especially in Europe, where there is a growing emphasis on going green.

Refrigerant choice and the future of air conditioning

The refrigerant decision is not only a technical issue, but also an environmentally and safety conscious one. In the coming years, the market will shift toward substances with low climate impact, which means that fewer and fewer units will run on R410A and more will run on R32 and natural refrigerants such as R290.

For installation and service companies, this means investing in training and equipment adapted to work with modern refrigerants that have different safety requirements. For residential and business customers, on the other hand, it is important to pay attention to the type of refrigerant used at the stage of choosing an air conditioner – a decision that affects user convenience, operating costs and care for the planet.

In time, air conditioners with low GWP refrigerants will be standard, and the choice between R32, R290 and other new substances will depend on the specifics of the installation site, safety requirements and individual preferences. It’s worth keeping up to date and consulting with experts who can help you choose the best solution, because good cooling is not just about comfort – it’s also about responsibility.

On hot days, air conditioning in a kindergarten can be a real saviour for both children and caregivers. However, the benefits of lowering the temperature go hand in hand with challenges – you need to ensure that the equipment is properly secured, that noise levels are controlled and that current standards and regulations are adhered to. In this text, we will look at the issue from several perspectives: we will discuss how to ensure the safety of toddlers, the impact of air-conditioning on acoustic comfort, as well as providing legal requirements and practical tips for the installation and maintenance of cooling systems in pre-school care facilities.

Safety for children in an air-conditioned environment

The correct positioning of indoor and outdoor air conditioning units is fundamental when it comes to the safety of preschoolers. Indoor units are usually mounted at a minimum height of two metres above the ground, which prevents children from reaching sharp edges or moving fan parts. In addition, the dust- and allergen-protecting filter should be secured so that toddlers cannot remove it – manufacturers often offer special clasps or clips that only allow adults to change the filter. It is also important to keep a sufficient distance from the main passageways of the rooms so that no one accidentally bumps into the condensate pipe or snags on the hoses.

The installation of ducting and condensate pipes should be done in a minimalist way to reduce places where people can trip or snag. All supply and connecting cables betweenoutdoor and indoor units should be concealed in special ducts or conduits with the appropriate fire resistance rating – this reduces the risk of insulation damage and short circuits. It is also worth remembering to protect the ventilation openings with fine filters to prevent small objects or insects from entering the ducts.

In addition to technical methods, supervision procedures are equally important – nursery staff should carry out regular visual inspections of the equipment, check the tightness of the pipes and the condition of the filters. If damage is detected, shutting down the equipment immediately and calling in a qualified service technician minimises the risk of accidents. Thanks to these measures, parents and carers can rest easy knowing that the cool air is not associated with additional risks.

Noise and the comfort of preschoolers

The noise generated by air conditioners can disturb the peace and quiet of both playing and resting preschoolers. Outdoor units, especially older models, can emit sounds of up to 60 decibels, which can feel like intense noise in an enclosed classroom setting. Children have been shown to be more sensitive to high-frequency sounds, so it is worth paying attention to the manufacturer’s stated volume levels for normal and quiet operation when selecting units.

Modern air-conditioning systems offer different modes of operation – night mode or quiet mode, in which the noise level drops to around 20-25 decibels, equivalent to a whisper or a breath of wind. It is also a good option to install ducted units hidden in the false ceiling, which, thanks to their design, emit a diffuse sound that is less perceptible by children. It is also a good idea to use mats and acoustic insulations around the outdoor units to reduce resonance and transmission noise.

At the same time, it should be borne in mind that any mode switching or sudden increase in the running power of the air conditioner can result in a momentary increase in noise, so programming smooth temperature changes and using intelligent thermostats with a soft start and stop function of the unit significantly increases comfort. Nursery schools that are concerned about silence often choose A++ or A+++ rated units, as they feature quieter operation and more stable heat dissipation.

Legal requirements and standards for air conditioning

The installation of air conditioning in an educational establishment is subject to a number of regulations and standards that aim to ensure health and safety. First and foremost, building regulations and regulations from the Minister of Health specify that children’s rooms must meet air exchange requirements – the minimum air exchange rate is usually 3-4 cubic metres per hour per person. In the technical documentation of the investment, the selection of units with the correct capacity must be taken into account, so that mechanical ventilation with heat recovery (recuperation) works together with air conditioning and ensures a full exchange of air without draughts.

In addition, the EN standards for refrigeration equipment specify what conditions the working refrigerant must meet in air-conditioning systems used in public facilities. The use of environmentally friendly refrigerants with low global warming potential (GWP), such as R32 or R290, is often required. Documentation should include leakage protocols for the installation and technical services must be carried out by certified professionals – F-gas qualification certificates can be proof.

Fire regulations also recommend that installation components are placed in separate fire zones and that smoke and chad detectors are installed in rooms with indoor units if the ductwork passes through different sectors of the building. It is also worth verifying local council resolutions – some municipalities impose additional requirements regarding the noise of outdoor units or their operating hours, especially in residential areas.

Good practice for installation and maintenance

The success of air conditioning use in a nursery depends largely on expert installation and regular maintenance. During installation, filters and main service components should be easily accessible, but kept out of the reach of children. Mounting the indoor units on sturdy brackets with anti-vibration pads reduces sound transmission and minimises the risk of them becoming detached. Condensate pipes are routed with a slope to allow water to drain freely, and small plumbing traps eliminate the risk of odours returning to the rooms.

Maintenance should include at least two service visits a year – before summer and winter. During the inspection, the tightness of the system, the condition of the filters, the cleanliness of the evaporator and condenser fins and the refrigerant level are checked. Cleaning the filters of dust and dirt prevents the growth of mould, which is of great importance for the health of toddlers. Consider installing HEPA filters or air purifiers with an ionisation function to further filter out bacteria and viruses.

It is also good practice to keep a service log – a record of each intervention, part replacement or refrigerant top-up enables analysis of the system’s operation and the detection of possible faults at an early stage. This keeps running costs under control and breakdowns less frequent. Finally, it is useful to train nursery school staff in day-to-day operation – simple tasks, such as cleaning filters or checking indicators on the control panel, can be carried out by themselves, which reduces response time and minimises the risk of downtime.

When implementing air conditioning in a kindergarten, it is worth remembering that the comfort and safety of toddlers is a priority. The right choice of equipment, attention to standards and regulations and meticulous maintenance will allow you to enjoy pleasant coolness without compromising on the health and peace of mind of the youngest users.

Although traditional air conditioning installation is often associated with a lot of mess, noise and damaged walls, today more and more people are opting for an alternative. Non-invasive installation is becoming a viable solution for those who want to enjoy cool air without having to tear out plaster or extensively interfere with the building structure. In the following text, we take a look at how such an installation looks in practice, what benefits it offers and what to look out for to avoid surprises.

Installation of air conditioning without drilling versus traditional methods

Traditional split air-conditioning installations require the indoor unit to be mounted on the wall, the refrigeration pipes to be connected and the condensate drained. In order to run the pipes to the outdoor unit, it was often necessary to chisel out the ductwork, drill into the wall in sections, and level the plaster and paint afterwards. The result? A lot of renovation costs, a lot of dust and a lot of disruption to the home.

Non-invasive installation eliminates most of these problems. Instead of forging, a small hole is drilled (usually Ø 65-75 mm) through which the cables are pulled. The drilling work is quick and, once completed, the installers seal the hole with an aesthetically pleasing plug, colour-matched to the façade or interior finish. As a result, the walls remain almost untouched and the flat is ready for use as soon as the installation is completed.

It is also worth mentioning monoblock systems, which eliminate additional refrigeration lines. In this solution, the entire unit – both condenser and evaporator – is installed inside or outside the building. A single drilling for the condensate drainage pipe is sufficient. This further reduces installation time and interference with walls.

Benefits of non-invasive installation

One of the biggest advantages of this approach is rapid installation. Experienced fitters can install a split unit in 2-4 hours, even in more difficult locations. The lack of forging also means that there is no dust in the entire flat – simply cover the floors and furniture appropriately to keep any potential contamination to an absolute minimum.

Another plus point is less noise. Forging and breaking a wall generates intense noises that can disturb householders and neighbours. Drilling with a diamond drill crown is much quieter and less intrusive. This is a significant benefit especially in blocks of flats where neighbours may make comments.

The aesthetics of the design must not be forgotten. Once completed, the opening is masked with an elegant cap made of PVC or stainless steel. Various colours and designs are available, so that the element blends in with the facade or interior wall. The builder gains full air-conditioning functionality, while the appearance of the flat remains intact.

Finally, the savings are worth mentioning. Although the price of a non-invasive installation may be slightly higher than for a traditional installation, the lack of wall renovation and painting saves on finishing work. For many people, it’s a win-win all round – they pay a little more for the installation, but avoid major renovation costs and the associated nerves.

Limitations and challenges of non-invasive installation

Despite its many advantages, it is not always possible to skip major building work. In older buildings, especially those with thick plaster or a layer of polystyrene as external insulation, reaching the load-bearing part of the wall may require longer drill rigs. This, in turn, entails higher labour costs and installation times.

It is also worth bearing in mind that drilling penetrates all layers of the wall – from plaster to insulation to hollow block or reinforced concrete. Any breach of the outer layers requires appropriate protection against moisture and loss of thermal insulation parameters. If the installation is carried out on a façade with an ETICS insulation system, an additional sleeve must be used to preserve the continuity of the insulation.

Another challenge is the location of the outdoor unit. In split installations, the refrigeration pipe connects the evaporator to the unit. If the unit is located far away, the pipes have to be longer and it becomes more difficult to insulate and route them properly without interfering with the wall. In practice, this means that the choice of installation location inside the room and the outdoor unit must be well thought out, and sometimes requires a compromise between aesthetics and efficiency.

Finally, there is the logistical problem – the availability of specialists. Not every air conditioning fitter offers a non-invasive installation service. You need to find a team that has the right equipment (diamond crown, milling machine) and experience. Before signing a contract, it is a good idea to ask for references and photos of previous installations.

What to look for when choosing an installer

If you want a non-invasive installation, check whether the company offers a ‘no-forging’, ‘drilling’ or ‘monoblock’ installation. When ordering a service, ask for details: what type of drill crowns are used, whether the drilling will lead through insulation, whether a protective sleeve needs to be fitted, and how the company intends to insulate the hole.

Also find out whether the company provides an aesthetically pleasing finish as part of the service – that is, caps that match the colour of the façade or wall. Some installers just leave the pipe open, hoping that the builder will take care of the aesthetics themselves. This can generate additional costs.

Pay attention to the length and type of guarantee. Reputable companies often offer a protection period of 2-5 years, covering both the equipment and the installation work carried out. It is a good idea if the warranty also covers drilling leaks and possible deformation of the walls.

Finally, check online reviews and local residents’ forums. Non-invasive installation is a relatively new service, so recommendations from previous customers are at a premium. If someone was happy with the dust-free and quick installation, there’s a good chance you’ll be happy with the result too.

Is it possible to have air conditioning without forging walls? As you can see, absolutely yes. A borehole or monoblock installation allows you to enjoy comfortable cooling without a lot of renovation and mess. All you need to do is choose the right system, an experienced team and remember to secure all layers of the partition firmly. Then summer in your flat or house will no longer be associated with hot air and stuffiness, but with pleasant coolness, without a single cavity in the wall.

What air conditioner do installers recommend in 2025?

Choosing an air conditioner in 2025 is a game of many variables: appearance, features, noise levels, efficiency and even the ability to fight allergens and viruses. Installers know best which models perform not only ‘on paper’, but also in actual use. Whether you’re looking for equipment for an elegant living room, a child’s room or a compact office – there’s something for you in this list. And remember – an air conditioner doesn’t just have to cool. It can also take care of your health and the quality of the air you breathe.

And if you still don’t know which one to choose… contact us – we’ll advise you on a model that meets all your expectations.

Installing air conditioning in a flat is an increasingly common step towards comfortable living – especially during the hot months, when temperatures in Polish cities can resemble southern Europe. However, before the cool breeze from the new unit arrives in the flat, it is worth preparing for the installation head-on. The purchase of the equipment itself is only the beginning – proper preparation of the flat not only makes the work of the installers easier, but also affects the efficiency of the entire system and avoids surprises. Not everyone knows that an improperly planned installation can lead to ventilation problems, dampness or even a breach of building regulations. In practice, good preparation is not only a technical issue, but also an organisational one. The better you plan everything before the team arrives, the quicker and more efficient the whole process will be.

Site selection is not just a question of aesthetics

One of the most important elements of preparation is deciding exactly where the air conditioning units – both indoor and outdoor – will be hung. Although this might seem like a task for the installer, the homeowner should already have considered the optimal location, taking into account not only the aesthetics of the interior, but also practical considerations. The interior should not be cluttered with furniture or curtains that could block the airflow. It is also necessary to think about access to an outlet, but it is not worth planning everything yourself – better to prepare several proposals and consult them with the installation team. Outside, the situation is sometimes more difficult, because the facades of buildings, especially in blocks of flats, are subject to the regulations of the housing association. You may need the administration’s permission to install an outdoor unit.

Sometimes technical or architectural constraints force less obvious solutions, such as mounting the unit on a neighbour’s roof or balcony. In such cases, additional arrangements and often technical documentation are required. It is worth checking how the condensate drainage works – not every system allows this without interfering with the drainage. When installing an air conditioner in the bedroom, it is better to avoid direct discharge onto the bed in order not to wake up in the morning with a cold and a sore throat. Before choosing a location, it is also worth considering whether there will be easy access for servicing and cleaning the unit. It’s better to take care of the ergonomics right away than to call in the professionals with a ladder to the ceiling later.

Walls that need to be ready for more than a drilling machine

Once the choice of location has been made, it is time to look at the walls themselves. In the case of flats in blocks of flats, you have to reckon with concrete, which can effectively make installation difficult. Installers often have to drill through the load-bearing wall to connect the indoor and outdoor units, which requires specialist equipment and time. It is a good idea to find out in advance what material the walls are made of and inform the team that will be installing the equipment. It is also good practice to secure the room – drilling generates a lot of dust and noise. If you don’t want to vacuum the whole bedroom afterwards, it’s better to move textiles, cover furniture and bring out small items.

Running the installation through several rooms can be an additional challenge, especially if you want a multi-split system. Every extra metre of refrigeration piping not only means a higher cost, but also potentially more forging and work. Sometimes it is worth considering flush-mounted pipework as early as the renovation stage – then the air conditioning installation is almost invisible. If an air conditioner is to go into a new build flat, it’s best to plan everything before plastering and painting. This avoids spoiling the finished walls later. In finished flats, it is worth asking the installers if they can use an industrial hoover – not every team does this on their own initiative.

Preparing the electrical installation is a subject not to be ignored

An air conditioner, although it may seem like a small appliance, can have a considerable appetite for electricity. Particularly in dwellings with older electrical installations, it is worth checking whether the current network can handle the extra load. It may be necessary to run a new circuit with a fuse dedicated only to the air conditioner. Ignoring this aspect can result not only in an overloaded network, but also in a real risk of failure. It is a good idea to have an electrician look at your home before the installers visit and assess whether everything is in order. This is also a good time to think about the location of the cables.

If the installation is to be invisible, you need to take this into account in your renovation plans – just like the power points in the kitchen or bathroom. In the case of surface-mounted installation, it is worth ensuring that the trunkings are colour-coordinated and fit snugly against the wall. Some companies offer aesthetically pleasing solutions that are easy to integrate into the interior – e.g. fascias styled with decorative elements. It is also worth making sure that the appliance will be powered from a standard socket or requires a separate connection to a distribution board. If you plan to automate your home, you can invest in an air conditioner with a Wi-Fi module and integrate it into your smart home system. This is not only convenient, but also saves energy.

Don’t forget the neighbours, the regulations and… your own comfort

Installing air conditioning is not only a technical issue, but also a social one. In blocks of flats, any additional element on the façade or a noisy outdoor unit can cause controversy among the neighbours. Therefore, in addition to the administration’s approval, it is worth simply talking to the people living next door. Nobody likes to be surprised by noise or repair work behind the wall. Besides, some buildings have internal regulations regarding the appearance of the façade or the hours of work. Ignoring such regulations can end up in removal or a fine.

It is also worth checking that the planned installation site does not interfere with gas, ventilation or water installations. Sometimes a seemingly ideal location may, in practice, turn out to be problematic in terms of health and safety regulations. It is good practice to sign a contract with the contractor that includes all the details – from the installation date to the guarantee. Such a contract protects both parties and gives confidence that the work will be carried out to a standard. Finally, remember that a well-prepared flat not only saves time, but also nerves. If you approach the subject comprehensively, air conditioning really becomes what it should be – a source of comfort and peace of mind in the home.

In a recording studio, silence is of paramount importance. Every murmur, which to the average ear is almost imperceptible, becomes an unbearable disturbance in a recording. This is why ventilation in such a place is not just a matter of comfort, but a technical necessity. How do you design a system that will ensure adequate air circulation and, at the same time, not spoil the sound quality? It’s not that simple – standard solutions don’t work here, and compromises quickly pay off. In this article, we take a look at the challenges faced by studio designers and the tried and tested ways that allow you to breathe fully… without background noise.

Silence is golden, or the acoustic challenges of ventilation

An ordinary ventilation system, used in offices or homes, emits sounds that are acceptable on a day-to-day basis – the hum of air, the gentle buzz of motors, the vibration of ductwork. In a recording studio, any of these noises can ruin the end result of your work. Studio microphones are extremely sensitive – they record not only vocals or guitar, but also the fan from the adjacent room. Therefore, the first step in planning the ventilation in such a venue is to understand how sound propagates and how it can be muted before it reaches the microphone. Sound insulation of the ventilation ducts and their appropriate positioning are essential here. The choice of materials is also not insignificant – flexible ducting with damping lining, so-called silencers (acoustic attenuators) and box-in-box, room-in-room enclosures.

The right length and routing of ducts can significantly reduce sound transmission. The more bends and attenuating elements in the air path, the less noise reaches the interior of the studio. It is sometimes necessary to introduce special acoustic chambers through which the air passes before it enters the room. It is also very important to separate the mechanical sound source from the structural elements of the walls and ceiling – so that vibrations are not transmitted. Professional studios often invest in individual systems with a dedicated technical room. Such a procedure increases costs, but gives peace of mind, which is invaluable when working with sound.

A draught-free circulation system

Even air distribution is another topic that requires a special approach in the context of a recording studio. In traditional HVAC (Heating, Ventilation and Air Conditioning) systems, air often comes in at high velocity through the supply grilles, resulting in audible turbulence and unpleasant draughts. In a studio, this is absolutely unacceptable. The system must be designed so that the flow is laminar – that is, calm, even, without turbulence. In practice, this means larger ducts, lower flow velocities and more supply and exhaust points. Often, the supply is provided via perforated ceiling panels that spread the air flow over a large area.

Thanks to this solution, air reaches every corner of the studio without any perceptible movement. This is very important when working with artists who spend long hours in the recording booth. Even a gentle draft can affect the voice or cause discomfort. Well-designed air distribution means not only silence, but also thermal comfort, which helps maintain focus. Even circulation also reduces the risk of zones of different temperatures – important for long sessions with heavy equipment loads. Every detail like this builds a professional working environment in which you can concentrate fully on the sound.

Ventilation vs. temperature and humidity control

Recordings often last for many hours and equipment generates heat – microphones, computers, preamps, studio monitors. In a small, sealed room without windows, the temperature can rise rapidly. Then there’s the issue of humidity, which affects the condition of instruments – especially acoustic instruments – and the health of the voices of recording artists. So you have to find a way to gently but effectively regulate the microclimate. You can’t just throw in a split air conditioner and hope it will take care of the problem. It too makes noise, even if it has a ‘quiet’ mode.

A much better solution is air handling units with heat recovery and a built-in cooling or reheating function. Such a system can work in the background, adjusting parameters to the needs of the users without interference. Modern systems can also integrate CO₂, temperature and humidity sensor systems that automatically manage ventilation intensity. This ensures that the air is always fresh, but without climate shocks. Humidity can be kept at an optimum level, which is important not only for people, but also for membrane microphones and wooden instruments. The right conditions also promote a longer life for electronic equipment – meaning savings on servicing.

The most common mistakes and how to avoid them

One of the most common mistakes made when adapting an acoustic room for a recording studio is to underestimate the role of ventilation. Sometimes, the investor focuses on acoustic panels, bass traps and carefully selected microphones, but forgets that a stuffy, un-air-conditioned room is no longer functional after two hours of a recording session. Another mistake is to install ventilation equipment without thinking about its sound path – a duct running directly into the neighbouring technical room can act as a resonance pipe, carrying any noise into the studio. It also happens that the installation works correctly in theory, but generates low-level noise – so-called “rumble” – which is undetectable to the naked ear but perfectly recorded by condenser microphones. This is why it is so important to work with a designer who understands not only ventilation but also acoustics. A good design is one that starts not with the question “how many m³/h we need”, but “where in this room will the microphones be and how does the sound propagate”.

Many installers have no experience of studio spaces and use solutions typical of offices. This is a road to nowhere – the studio is a completely different world. Saving on acoustic dampers and soundproofing the machine room should also be avoided. It is better to invest in a solution tailored to the conditions right from the start than to patch up the problem later with off-the-shelf flow “calmers”. When a studio operates quietly, reliably and without draughts, it allows you to concentrate fully on your creativity. And after all, that is what it is made for – to create, not to fight ventilation.
