How Window Air Conditioner (AC) Works? Working of Window AC

The working of window air conditioner can be explained by separately considering the two cycles of air: room air cycle and the hot air cycle. The compartments of the room and hot air are separated by an insulated partition inside the body of the air conditioner. The air moving inside the room and the front part of the air conditioner where the cooling coil is located is considered to be the cool air. When the window AC is started the blower starts immediately and after a few seconds the compressor also starts. The evaporator coil or the cooling gets cooled as soon as the compressor is started. The blower behind the cooling coil starts sucking the room air, which is at high temperature and also carries the dirt and dust particles.
