The main criterion for selecting an air conditioner is the area of the room that it will serve. Any air conditioner has its own operating parameters - it is designed to cool the air in a room of a certain area. Thus, the power should be selected based on a criterion of 1 kW for every 10 square meters of area (the height of the ceilings should not exceed three meters).
It is not at all necessary to make the selection of an air conditioner by area manually - for this there are special programs that will indicate the optimal parameters of the device for a particular room. Thanks to such software, you can find out about the cooling power, electric motor power, nominal air flow rate and some other parameters, on the basis of which the air conditioner can be selected correctly and efficiently.
An accurate calculation involves accounting for the amount of office equipment, incoming solar heat, the number of people in the room, isolation or the presence of communication with other rooms. All these parameters are taken into account directly when buying a particular model of air conditioner. Please note that the correct selection of air conditioners allows you to set the warranty period .
In addition to the general technical criteria, you should also decide on the design of the device. Monoblock design today is already losing its popularity, while the use of split systems is becoming more common. This is primarily due to the convenience of installation, because for a long time it was the installation of the air conditioner that was the main problem for buyers. When using split systems, the main source of noise is neutralized, as a result of which the indoor unit can be placed in any part of the room.
When selecting an air conditioner, you can pay attention to the devices that are mounted on the walls. Depending on the power, such an air conditioner can serve a room of up to 80 square meters. When more power is required, a cassette or channel system may be a good choice. This technological solution is used at such facilities as an office, restaurant, shopping center.
These systems are mounted under suspended ceilings, however, there are options in the form of decorated ceiling blocks. On sale, you can also find universal blocks that provide several installation options. If you need to maintain a small room, or you may need to move the air conditioner frequently, consider using a portable air conditioner.
Another solution to the problem of servicing a large number of rooms is to purchase a multi-split system. In this case, the selection of an air conditioner allows you to purchase a system that has several indoor units - they can be hung throughout the apartment or in several rooms of the office.
