A guide you should know before buying an air conditioner

When a room gets hot, many questions arise for people planning to install air conditioners in their homes or apartments. In our guide, we attempt to answer them.

Who uses air conditioning and when?

There are homes where the temperature is perfect even in the middle of summer, and the family feels comfortable. Then there are homes where, even on summer days, not the hottest ones, the heat is simply unbearable. Hot, humid, and stuffy environments... In those moments, all we think about is how to lower the temperature in the rooms.

There are many factors that affect the temperature in a home. Once we identify the conditions affecting us in our home, we can proceed with action: choose a system conditioning Equivalent.

Factors affecting home temperature during the summer

Glass walls , The windows are large and balcony doors They provide a significant increase in heat in winter, while in summer they cause problems with overheating rooms. When deciding on such popular glass today, you should consider using tinted adhesives.
Insufficient quantity of Sunscreen : Using awnings and curtains, especially those on the outside, significantly reduces heat gain from the sun. Roller blinds or interior curtains heat up through the glass and transfer heat into the room, so their efficiency is considerably lower.
Upper rooms It is likely to get hotter than rooms on the first floor below the attic or in a two-story house. This is because the attic creates a barrier that retains a significant portion of the solar heat, the roof acts as a thermal barrier, and windows on the facade allow considerably less solar heat in than skylights.
Exterior wall insulation : Properly chosen thermal insulation ensures that heat doesn't leak in during winter and doesn't penetrate during summer. Proper insulation significantly reduces the risk of overheating.
Framed buildings are more susceptible to temperature changes because their walls are relatively lightweight. Therefore, the temperature inside these buildings can rise very quickly due to heating from sunlight coming through the windows (the walls do not absorb heat).
Room height : The lower the room height, the higher its temperature. Since hot air is lighter than cold air, we will feel less discomfort in rooms with a height of 2.5-2.7 meters.

What type of air conditioner should you choose?

Portable air conditioners They are the cheapest solution. They can be easily moved from room to room. Their disadvantage is that they are noisy and have relatively low cooling power, as well as the need to vent exhaust air to the outside (for example, a pipe protruding from the window).
window air conditioners They are single-piece (monoblock) devices. They are installed within the building envelope (wall or window). Unfortunately, they are not aesthetically pleasing and make little noise, but the current atmosphere is quieter than their predecessors.
Split air conditioners (Removable) One of the most popular types of air conditioners. It consists of two units: External , which dissipates heat outside the building and internal This reduces the air temperature in the room. Split air conditioners are more efficient than single-unit units.
Air conditioners multi-split These are devices used to regulate the temperature in different rooms. The system consists of a coil. External unit and diverse Indoor units . Different temperatures can be set in each room.
Air conditioners Division and multi-division It is characterized by the fact that the unit that produces the most noise is located outside the building.

Air conditioning with R32 refrigerant

R32 coolant It has a lower potential to cause a global warming effect (GWP). 30% less of this factor is needed to fill an air conditioning system compared to the factor R410A . It is important to note that the R32 factor improves the energy efficiency of the air conditioner by 10%.

How do you choose the right air conditioner power?

Regarding the calculation of power A special program is needed to cool an air-conditioned room. With its help, sellers can determine the cooling demand very precisely, allowing them to select a custom-made device.

For rooms with a standard height (2.5-2.7 m), we can try to choose the air conditioner's power ourselves. It is assumed that 0.1 kW is needed per square meter of room surface. For example, a 2 kW unit would be suitable for a room of 20 square meters.

It is important to note that manufacturers make the selection process easier for us. In their technical specifications, they often provide information about the room and, in which area, a particular model will work.

However, it should be remembered that if the room is not enclosed, and air flows freely into another room, the total area of all rooms between which the air flows must be taken into account to calculate the power of the conditioned air.

Basic functions of air conditioning

Air conditioners can perform various functions. Their primary function is cooling. However, these devices... Heating or cooling They are being chosen more and more frequently.
While the concepts of heating and cooling may be familiar to everyone, the concept of a complete air conditioning system may be more valuable.
Complete air conditioning system When the device not only allows us to cool or heat the room, it also controls the humidity level inside; if necessary, it dries or humidifies the place.
It is also important that modern air conditioners are equipped Suitable filters Which ensures clean air in the home and additional functions, such as motion sensors or Wi-Fi control.
