Refrigeration system ya chowumitsira firiji ndi ya compression firiji, yomwe imapangidwa ndi zinthu zinayi zofunika monga firiji compressor, condenser, heat exchanger, ndi valavu yowonjezera. Iwo olumikizidwa motsatana ndi mipope kupanga chatsekedwa dongosolo, refrigerant mu dongosolo akupitiriza kuzungulira ndi kuyenda, kusintha dziko ndi kutentha kuwombola ndi wothinikizidwa mpweya ndi sing'anga yozizira, firiji kompresa adzakhala otsika kuthamanga (otsika kutentha) refrigerant mu chowotcha kutentha mu silinda ya kompresa, nthunzi ya refrigerant imapanikizidwa, kuthamanga ndi kutentha kumakwera nthawi yomweyo; Mpweya wothamanga kwambiri komanso wotentha kwambiri umakanikizidwa ku condenser, mu condenser, kutentha kwapamwamba kwa nthunzi yotentha komanso madzi ozizira kapena mpweya wokhala ndi kutentha kochepa kumasinthidwa kutentha, kutentha kwa firiji kumachotsedwa. madzi kapena mpweya ndi condensed, ndi refrigerant nthunzi amakhala madzi. Gawo ili lamadzimadzi limatengedwera ku valavu yowonjezera, yomwe imalowetsedwa mumadzi otentha komanso otsika kwambiri ndikulowa muzitsulo zotentha; M'malo otenthetsera kutentha, kutentha kwapansi, kutentha kwapansi, kutsika kwapansi kumatenga kutentha kwa kutentha kwapamwamba, mpweya wopanikizika kwambiri, ndipo kutentha kwa mpweya woponderezedwa kumachepetsedwa mokakamiza pamene akusunga kupanikizika komweko, zomwe zimapangitsa kuti pakhale kuchuluka kwakukulu. wa supersaturated madzi nthunzi. The refrigerant nthunzi mu kutentha exchanger ndi kuyamwa kutali ndi kompresa, kotero kuti refrigerant amadutsa njira zinayi psinjika, condensation, throttling ndi evaporation mu dongosolo, motero kumaliza mkombero.
