What to pay attention to before installing an air conditioner

January 15, 2021

One of the main characteristics of any air conditioner is its cooling capacity, which is indicated on the device in the form of numbers. These numbers fully correspond to the cooling capacity.

How to choose an air conditioner for your home or office based on cooling capacity? What type of device is needed to maintain a comfortable temperature in a particular room?

If we are talking about a small house or apartment, then it is possible to calculate according to a simplified scheme and correlate the required cooling power with the area of the room. It is accepted that 1 kW is enough to air condition a room of 10 m² (standard ceiling height less than 3 m).

If you want a more detailed calculation, which is especially important when determining the required cooling capacity of air conditioners , you should consider the following additional parameters , including:

Number of floors;
Location of the room (sunny or shady side);
Ceiling height;
Window glass area;
The average number of people in the room;
The amount of thermal energy released during the operation of household appliances and lighting devices.

For example, each person in a room brings about 100-150 W of heat. From the sunny side of the room, that is, from each window, about 300-400 W of heat enters. The heat released during the operation of household appliances and lamps is calculated from their nominal power and using the heat dissipation coefficient.

There are many factors and parameters to consider when calculating the cooling capacity of an air conditioner in detail, so it is best to leave this work to professionals.

What features are important when choosing an air conditioner besides power ?

Cooling capacity is a very important parameter, but it is by no means the only characteristic of the equipment. Below we present a few other characteristics that you can pay attention to.

We would also like to remind you that you can buy the desired model of air conditioner on our online store website, where we present air conditioners of various prices, brands, and capabilities. We offer both floor-standing air conditioners and wall-mounted split systems.

Energy efficiency class

Economy - a characteristic that can only be understood through the air conditioner's manual. The energy efficiency class of the device is indicated by Latin letters from A to G.

Air conditioners corresponding to class A are the most economical. The vast majority of air conditioners produced today are already classified as A ++ or even A +++.

Kh Mauri level

For many potential buyers of air conditioners, a parameter such as noise level is very important. The noise level of the quietest split system, the inverter type, is less than 20 dB.

The noise of a 20 dB device is comparable to the sound of a wall clock or a human whisper. Non-inverter models are somewhat noisier - from 30 to 45 dB.

Additional features

Some air conditioner models may have additional modes and functions. All of them serve only to create additional comfort. Some models even have too many additional functions. Therefore, before choosing such an air conditioner for an apartment or a summer cottage, think about how much you need all these functions, because you will undoubtedly have to pay more for increased comfort.
