Chingwe Chotenthetsera Chitseko Chozizira Chozizira mu Freezer

Chotenthetsera cha chitseko cha firiji ndi chinthu chotenthetsera chopangidwa mwapadera, chomwe chimagwiritsidwa ntchito kwambiri m'mafiriji, mafiriji ndi zida zina zoziziritsira. Ntchito yayikulu ya waya wotenthetsera chitseko cha firiji wosungunula ndikusungunula wosanjikiza wozizira womwe umapangidwa pamwamba pa evaporator kudzera mu kutentha, motero kuonetsetsa kuti zida zoziziritsira zikugwira ntchito mosalekeza komanso moyenera. Waya wotenthetsera chitseko cholukidwa nthawi zambiri umapangidwa ndi nickel-chromium alloy, chinthu chomwe chimagwiritsidwa ntchito kwambiri chifukwa cha kukana dzimbiri komanso kuyendetsa bwino magetsi.

Pa nthawi yomwe firiji ikugwiritsidwa ntchito, evaporator, chifukwa cha kutentha kwake kochepa kwambiri, imapangitsa kuti nthunzi ya madzi mumlengalenga isungunuke pamwamba pake ndikupanga chisanu pang'onopang'ono. Pakapita nthawi, makulidwe a chisanu adzawonjezeka nthawi zonse, zomwe sizimangokhudza mphamvu yosinthira kutentha kwa evaporator komanso zingayambitse kuchepa kwa mphamvu yozizira kapena kulephera kwa zida. Pofuna kuthetsa vutoli, mafiriji amakono nthawi zambiri amakhala ndi makina osungunula okha. Pamene sensa yomangidwa mkati izindikira kuti makulidwe a chisanu akupitirira malire okhazikika, makinawo adzayambitsa waya wotenthetsera wolukidwa ndi aluminiyamu kuti agwire ntchito yotenthetsera. Pakadali pano, waya wotenthetsera chitseko cha chisanu udzapanga kutentha kokwanira kuti usungunule chisanu kukhala madzi, omwe kenako amatuluka mu chipangizocho kudzera mu makina otulutsira madzi. Chinyezi chikasungunuka kwathunthu, waya wotenthetsera chitseko udzasiya kugwira ntchito, ndipo firiji idzabwerera nthawi yomweyo kuzizira kwake kwabwinobwino, kupitiriza kupatsa ogwiritsa ntchito malo oziziritsira kapena ozizira.
