1, chifukwa cha kusungunula mufiriji kapena kusindikiza sikuyenda bwino, zomwe zimapangitsa kuzizira kwakukulu
Chifukwa chake kusayenda bwino kwamafuta otenthetsera ndi chifukwa payipi, bolodi lotsekera ndi makulidwe ena osanjikiza sikokwanira, kutchinjiriza ndi kutenthetsa kwamafuta sikuli bwino, makamaka mapangidwe a makulidwe amtundu wosanjikiza samasankhidwa bwino kapena kumanga. za mtundu wa insulation ndi wochepa. Kuphatikiza apo, pakumanga, kukana kwazinthu zotchinjiriza chinyezi kumatha kuonongeka chifukwa cha chinyezi chosanjikiza, mapindikidwe, kapena ngakhale kuvunda, kutchinjiriza kwake kutentha ndi kutha kwa kutentha kumatsika, kutayika kozizira kumawonjezeka, kutentha kumachepa kwambiri. pansi. Chifukwa china chofunikira cha kutaya kuzizira ndi kusagwira bwino ntchito yosindikiza, pali mpweya wotentha kwambiri kuchokera pakuwukira kotayikira. Nthawi zambiri, ngati chosindikizira pachitseko kapena ozizira kabati kutentha kutchinjiriza kusindikiza chodabwitsa, zimasonyeza kuti chisindikizo si zolimba. Kuonjezera apo, kutsegula ndi kutseka kwa chitseko kawirikawiri kapena anthu ambiri pamodzi mu nyumba yosungiramo katundu, kudzawonjezera kutayika kozizira. Yesetsani kupewa kutsegula chitseko kuti muteteze mpweya wotentha kwambiri. Zachidziwikire, muzinthu zomwe nthawi zambiri kapena kuchuluka kwambiri kwa katundu, kutentha kumawonjezeka kwambiri, kuziziritsa mpaka kutentha komwe kumafunikira nthawi zambiri kumatenga nthawi yayitali.
2, evaporator pamwamba chisanu ndi wandiweyani kwambiri kapena fumbi kwambiri, kutentha kutengerapo zotsatira amachepetsa kuchititsa kuchepa pang'onopang'ono kutentha ndi chifukwa china chofunika kuti evaporator kutentha kutengerapo dzuwa ndi otsika, amene makamaka chifukwa cha evaporator pamwamba chisanu wosanjikiza. kufumbi lochuluka kapena lochuluka kwambiri lobwera chifukwa cha. Chifukwa ozizira kabati evaporator pamwamba kutentha ndi zambiri m'munsimu 0 ℃, ndi chinyezi ndi mkulu, chinyezi mu mlengalenga n'zosavuta mu evaporator pamwamba chisanu, kapena ayezi, zimakhudza kutentha kutengerapo zotsatira za evaporator. Pofuna kupewa evaporator pamwamba chisanu wosanjikiza ndi wandiweyani, m`pofunika defrost izo nthawi zonse.
Nazi njira ziwiri zosavuta zochepetsera madzi:
① kuyimitsa makina kuti asungunuke chisanu. Ndiko kuti, siyani kompresa kuthamanga, kutsegula chitseko, lolani kutentha kuwuka, kuti basi kusungunuka chisanu wosanjikiza, ndiyeno kuyambitsanso kompresa. ② Frost. Pambuyo kusuntha katundu mu mufiriji, mwachindunji ndi apamwamba kutentha kwa madzi wapampopi kugwetsa ndi evaporator chubu pamwamba, kuti chisanu wosanjikiza kusungunuka kapena kugwa. Kuwonjezera chisanu wandiweyani adzatsogolera evaporator kutentha kutengerapo kwenikweni si zabwino, ndi evaporator pamwamba chifukwa cha nthawi yaitali popanda kuyeretsa ndi fumbi kudzikundikira ndi wandiweyani, kutentha kwake kutengerapo Mwachangu nawonso kwambiri yafupika.
3, supermarket freezer evaporator pamaso pa mpweya wambiri kapena mafuta a firiji, kutentha kwa kutentha kumachepa.
Kamodzi evaporator kutentha kutengerapo chubu Ufumuyo pamwamba pamwamba pa mafuta owuma kwambiri, kutentha kwake kutengerapo koyenelera kuchepetsedwa, chimodzimodzi, ngati pali mpweya wochuluka mu chubu kutengerapo kutentha, evaporator kutentha kutengerapo dera yafupika, kutentha kutengerapo. Kuchita bwino kudzachepetsedwa kwambiri, ndipo kutentha kwa kutentha kumachepetsedwa. Choncho, mu ntchito tsiku ndi kukonza, ayenera kulabadira kuchotsa yake evaporator kutentha kutengerapo chubu pamwamba mafuta ndi kutulutsa mpweya mu evaporator, kuti kusintha kutentha kutengerapo dzuwa la evaporator.
4, valavu yopumira yosasinthidwa bwino kapena yotsekeka, kutuluka kwa refrigerant ndikokulirapo kapena kochepa kwambiri
Valavu ya Throttle yosayendetsedwa bwino kapena yotsekedwa, idzakhudza mwachindunji kutuluka kwa refrigerant mu evaporator. Pamene valavu ya throttle ili yotseguka kwambiri, kutuluka kwa refrigerant ndi kwakukulu, kuthamanga kwa evaporative ndi kutentha kwa evaporative kumawonjezeka, kutsika kwa kutentha kumachepa; panthawi imodzimodziyo, pamene valve yotsekemera imatsegulidwa yaying'ono kwambiri kapena yotsekedwa, kutuluka kwa firiji kumachepetsedwanso, mphamvu ya firiji ya dongosolo imachepetsedwanso, kutentha kwa chipinda chosungirako kudzachepetsa kuchepetsa kuchepa. Nthawi zambiri poyang'ana kuthamanga kwa evaporation, kutentha kwa evaporation ndi chisanu choyamwa chitoliro kuti muwone ngati kutuluka kwa refrigerant ndikoyenera. Kutsekeka kwa Throttle ndichinthu chofunikira chomwe chimakhudza kuyenda kwa firiji, kupangitsa kutsekeka kwa throttle ndiye chifukwa chachikulu cha pulagi ya ayezi ndi pulagi yonyansa. Ice pulagi ndi chifukwa kuyanika zotsatira za chowumitsira si bwino, refrigerant muli madzi, kuyenda mu valavu throttle, kutentha akutsikira pansi 0 ℃, chinyezi mu refrigerant mu ayezi ndi kutsekereza throttle dzenje; pulagi zauve ndi chifukwa throttle valavu inlet fyuluta mauna pa kudzikundikira ambiri dothi, refrigerant otaya si yosalala, mapangidwe blockage.
