Kusanthula kwa refrigeration mfundo ya otentha a mafakitale

Compressor imayamba kufinya firiji ikayamba. Inde, imayamwa mufiriji kuchokera kumbali yake yoyamwa. Pambuyo pa compressor wa firiji compresses, izo zimapanga mpweya wotentha kwambiri komanso wothamanga kwambiri. Dziwani kuti ikayamwa, imakhalanso mpweya, womwe umadutsa ntchito ya firiji compressor. Pambuyo popanikizidwa ndi kutentha kwakukulu komanso mpweya wothamanga kwambiri, umatulutsidwa kupyolera kumapeto kwa compressor.

Gasi wotulutsidwa mufiriji adzalowa mu condenser kudzera papaipi ya refrigerant. Pambuyo polowa mu ndondomeko ya condensation, chifukwa cha kutentha kwakukulu ndi kuthamanga kwa firiji, firiji idzagwiritsa ntchito condenser kuti iwononge kutentha. Condenser ndi chipangizo chosinthira kutentha kudzera m’madzi ozizira kapena mpweya. (Air force convection) Njira ziwirizi zochotsera kutentha zimayendetsa kutentha.

Kutentha kutatha, firiji idzasintha kuchokera ku gasi wa refrigerant kupita kumadzi ozizira chifukwa cha kutentha kwa kutentha, ndiyeno kulowa mu valve yowonjezera kutentha. Valve yowonjezera (valavu yowonjezera kutentha imagwiritsidwa ntchito nthawi zambiri) ndi gawo lochepetsera komanso kuchepetsa kupanikizika, zomwe zimadalira kutentha ndi Kuthamanga kumakhala kosiyana, ndipo madoko a valve a kukula kosiyana amatsegulidwa. Pambuyo podutsa mu valve yowonjezera, madzi a refrigerant salinso madzi otsika komanso othamanga kwambiri pambuyo pa condensation, koma ndi madzi otsika komanso otsika kwambiri.

Kenako, otsika-kutentha ndi otsika-anzanu refrigerant madzi akudutsa evaporator wa mufiriji. Refrigerant yotsika kwambiri komanso yotsika kwambiri imadutsa munjira ya evaporator kuti ipange mphamvu yozizira, kenako mphamvu yozizira imaperekedwa m’madzi ozizira, ndipo madzi ozizira amagwiritsidwa ntchito ngati firiji kunyamula kuzizira mpaka kumapeto. Zida kapena chandamale chozizirira!
