In order not to make a mistake with the choice of an air conditioner, first of all it is necessary to take into account not the cost and the manufacturer, but the power of the device, which should exactly correspond to the area of the room where its installation is provided. As a rule, manufacturers indicate these data in the technical specifications. If there are no such indicators, then you can make the calculation yourself, knowing that about 1 kW is needed for 10 m2. However, this method will still not give an accurate result, since possible heat losses were not taken into account during the calculation.

If you want to choose the most optimal option, then it is better to contact qualified specialists for this. They calculate according to a complex formula, which takes into account not only the area of the room, but also the height, heat flows arising from the difference in air temperature outside and indoors, solar radiation. Also taken into account are such moments as the type of glazing, the time the room is illuminated by the sun, the side of the location of the room (south or north), the availability and quantity of computer, office equipment and other equipment, and the number of people in the room. Plus, 20% is added to the result obtained, intended for unaccounted heat flows.

In addition to power, it is necessary to take into account the type of device (inverter or linear), as well as functionality, equipment modes and optional features. The important ones are:

• device cleaning system that prevents mold formation inside the system;


• the "smart eye" function, which allows you to determine the location of a person and adjust the direction of air flows accordingly;


• the ability to install a Wi-Fi module for remote control;


• cleaning the air from dust, allergens and microbes.

The working life of household air conditioners is set by the manufacturer and varies on average from 9 to 12 years, provided they work no more than 12 hours a day and 6 days a week. But, this indicator can both increase and decrease. The exact service life will depend on compliance with the rules and operating conditions, the quality of the blocks themselves and their installation, and the regularity of maintenance.

• Inverter - The advantages of inverter split systems are that inverter split systems automatically adjust the cooling power in the room, which allows you to maintain the desired temperature in the room and save up to 30% of electricity. Inverter air conditioners can work for heating at negative temperatures (up to -15 ° C).
• Non-inverter (on / off) - maintain the required temperature, periodically turning on / off the compressor, due to which more electricity is consumed. Non-inverter air conditioners change the temperature in the room more slowly and work much louder. Their significant advantage over inverter is only lower cost. The equipment can work for heat and cold, but only at temperatures up to -5C.
• Wall-mounted split systems can be installed in a small room - an office, an apartment, a store. The indoor unit of such air conditioners is usually installed at the top of the wall, not far from the window, and the outdoor unit is under the window or on the loggia.
• Cassette split systems are ideal for installing the air conditioner in a false ceiling (Armstrong). The lower part of the cassette split system has the size of a standard ceiling tile - 600 × 600 mm and is covered with a decorative grille with distribution shutters, which makes it invisible. The cassette air conditioner distributes air flows in 4 directions, which is very convenient for large areas. The power varies from 5 to 30 kW, which allows you to cool a room from 40 to 350 sq.m.
• Channel split systems are usually installed behind a false ceiling, which completely hides the indoor unit of the air conditioner. Ducted air conditioners can cool several rooms at once. The standard power of ducted air conditioners ranges from 12 to 25 kW - this is enough to cool a small office, a cottage or a large apartment. An important feature is the ability to supply fresh air for full ventilation of air-conditioned rooms.
• Column split systems are used mainly where high cooling capacity is required and there are no strict requirements for the design of the room. These air conditioners resemble a refrigerator in size, are heavy and are installed on the floor. Column air conditioners require a relatively large area for their placement, since they create a strong flow of chilled air, which does not allow being in close proximity to the air conditioner.
• Floor - ceiling split systems - differ in a small depth of 18 to 25 centimeters. Mounted either at the bottom of the wall or on the ceiling. The air flow in the first case is directed upwards, in the second case it is directed horizontally along the ceiling, which makes it possible to distribute the cooled air more evenly throughout the room and avoid direct contact of the cold flow with people. Ceiling air conditioners are used to cool rooms of complex shape without a false ceiling, for hidden installation
