Mu bokosi la evaporation la galimoto muli zinthu ziwiri, chimodzi ndi thanki yofunda ya mpweya, chimodzi ndi choziziritsira mpweya, madzi omwe ali mu thanki yamadzi ya galimoto ndi otentha, madzi omwe amalowa mu thanki yofunda ya mpweya, mphepo yomwe imawomba ndi fan ndi mpweya wofunda, ndipo mukatsegula firiji, thanki yofunda ya mpweya imayimitsa madzi, choziziritsira mpweya chinayamba kugwira ntchito, choziziritsira cha compressor kulowa mu air conditioner, chikutuluka mumlengalenga wozizira wachilengedwe.
Bokosi loyatsira mpweya wa galimoto ndi chipangizo choyatsira mpweya wa galimoto chomwe chimagwiritsa ntchito injini ya galimoto komanso choyatsira mpweya wa galimoto. Ntchito ya bokosi loyatsira mpweya wa galimoto ndikusintha firiji kuchoka pamadzi kupita ku mpweya (monga kuyandama kwa mpweya), kuyamwa kutentha kwambiri mozungulira, kenako kutentha kochepa ndi nthunzi yotsika ya firiji kulowa mu compressor, ndi kuzungulira kwa ndondomekoyi kuti kukwaniritse cholinga cha kutentha kochepa. M'chilimwe, kupereka malo abwino oyendera kwa okwera, kuchepetsa mphamvu ya woyendetsa, ndikuwongolera chitetezo choyendetsa.
