Wall split air conditioners consist of indoor and outdoor unit, equipped with remote control, equipped with a variety of options for cleaning the air, ease of operation, the compressor can be fixed and variable (inverter) power. The indoor unit is designed for installation on the wall, on the ceiling of the room.
This type of air conditioners is the most popular as a compressor and a condenser cooling fan (located in the outer, “street” block) are separated from the evaporator blower (located in the interior, “indoor” unit). This scheme was introduced in the 60s of the 20th century, when the designers set out to reduce the noise level and the size of air conditioners, for wide application in daily life, previously produced only windows and industrial monoblock system, which severely limits their use in homes and offices. “Split” means “separated” – vnturenny and outdoor unit connected pipes forward and reverse pumping Freon (refrigerant -teplonositelya), the pressure created by the compressor and throttle valve, which ensures the Carnot cycle in the specified temperature limits. Upon reaching the desired temperature in the room, the compressor is deactivated. In split-system inverter compressor operates at a variable speed, and this provides another “degree of freedom” for providing a more accurate temperature control.
