1, chifukwa cha kutchinjiriza kwa mufiriji kapena kutseka kwake, ntchito yake ndi yoipa, zomwe zimapangitsa kuti kuzizira kutayike kwambiri
Chifukwa chomwe kutenthetsa koipa sikukwanira chifukwa mapaipi, bolodi lotenthetsera ndi makulidwe ena a kutenthetsera sikokwanira, kutenthetsa ndi kutenthetsa sikuli bwino, makamaka chifukwa chakuti makulidwe a kutenthetsera sasankhidwa bwino kapena kapangidwe ka zinthu zotenthetsera sikoyenera. Kuphatikiza apo, pomanga, kukana kwa chinyezi cha zinthu zotenthetsera kumatha kuwonongeka zomwe zimapangitsa kuti chinyezi cha kutenthetsera, kusintha, kapena kuwola, kutenthetsa kwake kutentha ndi kutenthetsa kutentha kuchepe, kutayika kwa kuzizira kumawonjezeka, kutentha kumatsika kwambiri. Chifukwa china chofunikira cha kutayika kwa kuzizira ndi kutayika kwa kutenthetsa koipa, pali mpweya wotentha wambiri wochokera ku kulowa kwa kutayikira. Nthawi zambiri, ngati mzere wotsekera pachitseko kapena chochitika chotenthetsera kutentha cha kabati yozizira, zimasonyeza kuti chisindikizocho sichili cholimba. Kuphatikiza apo, kutsegula ndi kutseka chitseko pafupipafupi kapena anthu ambiri pamodzi kulowa m'nyumba yosungiramo zinthu, kudzawonjezera kutayika kwa kuzizira. Muyenera kuyesetsa kupewa kutsegula chitseko kuti mupewe mpweya wotentha wambiri. Zachidziwikire, muzinthu zomwe zili m'sitolo nthawi zambiri kapena zambiri, kutentha kumawonjezeka kwambiri, kuti kuzizire mpaka kutentha kofunikira nthawi zambiri kumatenga nthawi yayitali.
2, chisanu pamwamba pa evaporator ndi chokhuthala kwambiri kapena fumbi lochuluka kwambiri, mphamvu yotumizira kutentha imachepa zomwe zimapangitsa kuti kutentha kuchepe pang'onopang'ono ndi chifukwa china chofunikira chomwe chimapangitsa kuti kutentha kwa evaporator kukhale kochepa, chomwe chimachitika makamaka chifukwa chakuti chisanu pamwamba pa evaporator ndi chokhuthala kwambiri kapena fumbi lochuluka kwambiri lomwe limayambitsidwa ndi. Chifukwa cha kutentha kwa pamwamba pa evaporator m'kabati kozizira kwambiri kumakhala pansi pa 0 ℃, ndipo chinyezi chimakhala chokwera, chinyezi mumlengalenga chimakhala chosavuta kwambiri mu chisanu pamwamba pa evaporator, kapena ngakhale ayezi, zomwe zimakhudza mphamvu yotumizira kutentha kwa evaporator. Pofuna kupewa kuti chisanu pamwamba pa evaporator chikhale chokhuthala kwambiri, ndikofunikira kuchisungunula nthawi zonse.
Nazi njira ziwiri zosavuta zosungunulira:
① Letsani makina kuti asungunuke chisanu. Ndiko kuti, letsani compressor ikuyenda, tsegulani chitseko, lolani kutentha kukwere, kuti chisungunuke chokha, kenako yambitsaninso compressor. ② Frost. Mukachotsa katundu mufiriji, tsanulirani madzi a m'mapopi mwachindunji ndi kutentha kwakukulu pamwamba pa chubu cha evaporator kuti chisungunuke kapena kugwa. Kuwonjezera pa chisanu chokhuthala, kutentha kwa evaporator sikuli bwino, chifukwa cha nthawi yayitali popanda kuyeretsa komanso fumbi lochuluka kwambiri, mphamvu yake yotumizira kutentha idzachepa kwambiri.
3, chotenthetsera choziziritsira mufiriji cha supermarket ngati pali mpweya wambiri kapena mafuta oziziritsa, kutentha kumachepa
Chitoliro chotenthetsera kutentha cha evaporator chikalumikizidwa mkati mwa mafuta oundana kwambiri, mphamvu yake yosamutsa kutentha idzachepa, chimodzimodzi, ngati pali mpweya wochulukirapo mu chubu chotenthetsera kutentha, malo osamutsa kutentha a evaporator amachepa, mphamvu yosamutsa kutentha idzachepanso kwambiri, ndipo kutentha kumachepa pang'onopang'ono. Chifukwa chake, pakugwira ntchito ndi kukonza tsiku ndi tsiku, muyenera kusamala kuti mafuta a pamwamba pa chubu chotenthetsera kutentha cha evaporator achotsedwe nthawi yake ndikutulutsa mpweya mu evaporator, kuti muwongolere mphamvu yosamutsa kutentha ya evaporator.
4, valavu yotsekereza yolakwika kapena yotsekeka, kayendedwe ka refrigerant ndi kakang'ono kwambiri kapena kakang'ono kwambiri
Valavu yotsekereza mpweya ikayendetsedwa molakwika kapena kutsekeka, imakhudza mwachindunji kayendedwe ka refrigerant kulowa mu evaporator. Valavu yotsekereza mpweya ikatsegulidwa kwambiri, kayendedwe ka refrigerant kamakhala kwakukulu, kuthamanga kwa evaporative ndi kutentha kwa evaporative kumawonjezeka, kutsika kwa kutentha kudzachepa; nthawi yomweyo, valavu yotsekereza mpweya ikatsegulidwa pang'ono kwambiri kapena kutsekeka, kuyenda kwa refrigerant kumachepanso, mphamvu ya refrigerant ya dongosolo imachepanso, kutentha kwa chipinda chosungiramo mpweya kudzachepanso. Nthawi zambiri poyang'ana kuthamanga kwa evaporative, kutentha kwa evaporative ndi chisanu cha chitoliro chokoka mpweya kuti mudziwe ngati kuyenda kwa throttle refrigerant kuli koyenera. Kutsekeka kwa throttle ndi chinthu chofunikira chomwe chimakhudza kayendedwe ka refrigerant, zomwe zimapangitsa kuti throttle itsekeke ndiye chifukwa chachikulu cha plug ya ayezi ndi pulagi yodetsedwa. Plagi ya ayezi imachitika chifukwa cha mphamvu youma ya chowumitsira si yabwino, refrigerant imakhala ndi madzi, imayenda kudzera mu valavu yotsekereza mpweya, kutentha kumatsika kufika pansi pa 0 ℃, chinyezi mu refrigerant kulowa mu ayezi ndikutseka dzenje la throttle; Pulagi yodetsedwa imayambitsidwa ndi maukonde a fyuluta yolowera mu throttle valve pamene dothi lalikulu likusonkhanitsidwa, madzi oyenda mufiriji sakuyenda bwino, ndipo kutsekeka kwa madzi kumapangidwa.
