Mobile options only need to be connected to the mains, there is no need to mount anything on the wall. However, they are quite expensive and make noise at work. Coolers work due to water evaporation inside the device. Two-unit analogs are a classic split system with refrigerant and compressor, in only one case and with a corrugated pipe to remove heated air from the room. The use of the ATEX Air Conditioners comes up.
Multi-split, as well as relatively complex and expensive supply and exhaust ventilation, are practically not used in low-rise private houses. This technique is mainly intended for industrial and office buildings.
Air conditioners and selection criteria
When choosing which air conditioner is better to go buy for a home, you need to consider:
- energy efficiency and performance of a specific model;
- operating conditions – the equipment will stand on the floor, hung on a wall or mounted on a window;
- functional requirements – whether, in addition to cooling, a heating mode is also required;
- the noise level of the equipment (30–35 dB or less are considered comfortable);
- need for additional filters and air ionizers.
- what to consider when choosing an air conditioner
Heat sources in the house
If for a small room only “COOLING” is required, then the best choice would be – a compact low-power mobile-type cooler. It does not make much noise, effectively cools the air and consumes little electricity.
But for a cottage built in a warm region, it is worth choosing a split system. It is difficult to come up with the best air conditioner for such conditions. In the summer, it will cool, and at temperatures outside the window around zero, it will heat room air to comfortable levels. This is not a full-fledged heating system, but in the absence of Siberian frosts on the street, such a technique is quite able to cope with heating the housing.

Air conditioner power calculation
The most important parameter for choosing an air conditioner is its power. And here we are not talking about energy consumption, but about the capabilities of equipment for cooling a room of a certain size.
For a simplified calculation of the required capacity of the air conditioner for cooling, you must use the formula:
- Qp = Qv + Qm + Qt
- The following capacities are taken into account in this formula:
- Qp – total calculated;
- Qv – required for cooling a room of a certain cubature, taking into account insolation;
- Qm – needed to compensate for the thermal energy generated by people in the room;
- Qt – necessary to compensate for the heat produced by household appliances.
An example of calculating the power for a room
Qv = V * q (where V is the volume of the room, and q is the insolation coefficient). If the room faces north or northeast with windows, then q is taken as 30 W / m. cube If it is located in the house from the south, southwest or southeast side, then 40 W / m should be taken into account. cube In other cases, q = 35 W / m. cube
