Pali zinthu ziwiri mu bokosi la evaporation lagalimoto, imodzi ndi thanki yotentha, imodzi ndi air conditioner, madzi mu thanki yamadzi yagalimoto ndi otentha, kulowa mu thanki yamoto yotentha, mphepo yowomberedwa ndi fani ndi mpweya wofunda, ndipo mukatsegula firiji, thanki yotentha imayimitsa madzi, zoziziritsira mpweya zinayamba kugwira ntchito, mpweya wozizira wa compressor, kuwulutsa mpweya wachilengedwe mufiriji.
Bokosi la evaporation lagalimoto ndi injini yamagalimoto ndi chipangizo cha radiator chowongolera mpweya wamagalimoto. Ntchito ya bokosi la evaporation la zowongolera mpweya wamagalimoto ndikupanga refrigerant kusintha kuchokera kumadzi kupita ku gasi (ie evaporation), kuyamwa kutentha kwambiri mozungulira, kenako kutentha pang'ono ndi mpweya wochepa wa refrigerant mu kompresa, ndi kuzungulira kwa njirayo kukwaniritsa cholinga cha kutentha kochepa. M'chilimwe kuti apereke malo abwino okwera kwa omwe akukhalamo, kuchepetsa kutopa kwa dalaivala, kuwongolera chitetezo chagalimoto.
