Kodi ntchito za zinthu zinayi zazikuluzikulu ndi ziti mu firiji dongosolo firiji?

1. Compressor: Ndi mtundu wa makina amadzimadzi omwe amalimbikitsa mpweya wochepa kwambiri mpaka mpweya wothamanga kwambiri. Ndiwo mtima wa firiji, womwe umapereka mphamvu pamayendedwe a firiji, kuti azindikire kuzungulira kwa firiji → condensation (kutulutsa kutentha) → kufutukuka → evaporation (kuyamwa kwa kutentha). Ndipo pali mitundu yambiri ya compressor. Kugwira ntchito bwino kwa mitundu yosiyanasiyana ya compressor ndikosiyananso.

2. Condenser: The condenser is a heat exchange device. Its function is to use the ambient cooling medium (air or water) to take away the heat of the high-temperature and high-pressure refrigerant vapor from the cold compressor, so that the high-temperature and high-pressure refrigerant vapor is cooled and condensed into High pressure and normal temperature refrigerant liquid. It is worth mentioning that in the process of the condenser changing the refrigerant vapor into the refrigerant liquid, the pressure is constant, and it is still high pressure.

3. Evaporator: Ntchito ya evaporator ikufanana ndi condenser yomwe tatchula pamwambapa, chifukwa ndi chipangizo chosinthira kutentha. The otsika kutentha ndi otsika-anzanu refrigerant madzi pambuyo throttling amasanduka nthunzi (zithupsa) mu nthunzi mmenemo, zimatenga kutentha kwa zinthu kuti utakhazikika, amachepetsa kutentha zinthu, ndi kukwaniritsa cholinga kuzizira ndi refrigerating chakudya. Mu air conditioner, mpweya wozungulira umakhazikika kuti ukwaniritse zotsatira zoziziritsa ndi kuchepetsa mpweya.

4. Valavu yowonjezera: Vavu yowonjezera nthawi zambiri imayikidwa pakati pa silinda yosungiramo madzi ndi evaporator. The valavu kutambasuka kumapangitsa sing’anga kutentha ndi mkulu-anzanu madzi refrigerant mwa throttling ake mu otsika kutentha ndi otsika-anzanu chonyowa nthunzi, ndiyeno refrigerant zimatenga kutentha mu evaporator kukwaniritsa kuzirala kwenikweni. Valavu yowonjezera imayang’anira kuthamanga kwa valve posintha kutentha kwapamwamba kumapeto kwa evaporator kuti zisachitike. M’mafakitale oziziritsa mufiriji, amathandizira kwambiri kugwedezeka, kuchepetsa kupanikizika komanso kusintha koyenda. Valavu yowonjezera imakhalanso ndi ntchito yoteteza kupsinjika kwamadzi ndi kugwedezeka kwamadzimadzi kuti muteteze compressor ndi kutenthedwa kwachilendo.
