Chidziwitso cha kapangidwe kake ndi mfundo zogwirira ntchito za chiller

Mapangidwe ndi mfundo ya chiller Makina a firiji amapangidwa makamaka ndi condenser, kompresa, capillary chubu, evaporator ndi zowumitsa zosefera.

Mfundo yake yogwirira ntchito ndi: firiji ya mpweya, yotsika komanso yotsika kwambiri yotuluka mu evaporator imayamwa mu kompresa ya firiji, ndipo kompresa ya firiji imayiyika mufiriji yotentha kwambiri komanso yothamanga kwambiri, yomwe imasamutsidwa. ku condenser. Mafiriji okhala ndi mpweya, kutentha kwambiri komanso kupanikizika kwambiri mu condenser amasamutsa kutentha kwakukulu kupita kumlengalenga kunja kwa bokosilo kuti asunge kutentha kwawoko kuti kusakhale kokwera kwambiri, kenako ndikudutsa mu chowumitsira chowumitsira, pomwe firiji. zouma ndi zosefedwa Kuchepa kwa chinyezi ndi zonyansa zomwe zili mkati mwazokha, ndiyeno madzi othamanga kwambiri a refrigerant opanda zonyansa zonyowa amasinthidwa kukhala mpweya wochepa kwambiri komanso wochepa kutentha wonyowa kupyolera mu kugwedeza kwa chubu cha capillary. Nthunzi yonyowa imasanduka nthunzi ndi kuwira, ndipo imatenga kutentha kuchokera kumalo ozungulira evaporator kuti ikhale mpweya wotentha komanso wochepa kwambiri, ndipo pamapeto pake imayamwa mu kompresa kachiwiri, kubwereza kuzungulira kotsatira. Firiji imazungulira mobwerezabwereza mu dongosolo lotsekedwa ili, kotero kuti kutentha m’bokosi kumachepetsedwa, kuti akwaniritse cholinga cha firiji.
