Air conditioning heating, cooling, cleaning, circulation, and the process of continuously providing and establishing the function of keeping the moisture content of the air at a certain level. Even though the partial realization of these is not an entire air conditioner alone, controlling one or more of them is also referred to as air conditioners today. Devices formed by placing cooling system elements in two or more bodies are called "split type air conditioners". Split air conditioners consist of an outdoor unit and one or several (multi split) indoor units. While operating in the cooling mode, the heat of the indoor environment is taken from the outdoor unit by means of the refrigerant and discharged to the atmosphere from the outdoor unit. In the heating mode (heat-pump), the system discharges the cold inside out through the outdoor unit and heats the indoor environment. Refrigerant circulation between indoor and outdoor units is provided by insulated copper pipes. 7.000 Btu / h. - 24.000 Btu / h. Having a cooling-heating capacity of between, air conditioners are generally preferred in residences and small offices. 24.000 Btu / h. with 60.000 Btu / h. They are also available for commercial-type applications (store, large office, cafe, etc.). Mono split air conditioner consists of an indoor and outdoor unit. Multi split air conditioner consists of an outdoor unit and multiple indoor units.
