1, chisanu pamwamba pa evaporator yoziziritsa ndi chokhuthala kwambiri kapena fumbi lochuluka kwambiri, mphamvu yosamutsa kutentha imachepa
Gawoli ndi lokhuthala kwambiri kapena fumbi lochuluka kwambiri. Popeza kutentha kwakukulu kwa pamwamba pa evaporator yosungiramo zinthu zozizira m'firiji kuli pansi pa 0 ℃, komanso chinyezi chambiri cha m'nyumba yosungiramo zinthu, chinyezi chomwe chili mumlengalenga n'chosavuta kuzizira pamwamba pa evaporator, kapena ngakhale ayezi, zomwe zimakhudza momwe evaporator imasamutsira kutentha. Pofuna kupewa kuti gawo la chisanu pamwamba pa evaporator likhale lokhuthala kwambiri, ndikofunikira kulisungunula nthawi zonse.
Nazi njira ziwiri zosavuta zosungunula: ① kuletsa chisanu. Izi zikutanthauza kuti, siyani compressor kugwira ntchito, tsegulani chitseko cha nyumba yosungiramo zinthu, kuti kutentha kwa nyumba yosungiramo zinthu kukwere, kuti chisungunuke chokha, kenako yambitsaninso compressor. ② Chisa. Mukachotsa katundu m'nyumba yosungiramo zinthu, tulutsani mwachindunji ndi madzi otentha kwambiri pamwamba pa chubu cha evaporator, kuti chisanucho chisungunuke kapena kugwa. Kuphatikiza pa chisanu chokhuthala, chingayambitse kusamutsa kutentha kwa evaporator, pamwamba pa evaporator ndi wandiweyani kwambiri chifukwa cha nthawi yayitali popanda kuyeretsa ndi kusonkhanitsa fumbi, mphamvu yake yosamutsa kutentha idzachepa kwambiri.
2, malo osungiramo ozizira mufiriji chifukwa cha kutenthetsa kosakwanira kapena kutseka bwino, zomwe zimapangitsa kuti kuzizira kutayike kwambiri
Kusagwira bwino ntchito kwa kutentha chifukwa cha payipi, makulidwe a khoma la nyumba yosungiramo zinthu zo ...
Chifukwa china chofunikira cha kutayika kwa kuzizira ndi kusagwira bwino ntchito kwa nyumba yosungiramo zinthu, mpweya wotentha umakhala wambiri kuchokera ku kutuluka kwa mpweya kupita ku nyumba yosungiramo zinthu. Nthawi zambiri ngati mzere wotsekera pachitseko cha nyumba yosungiramo zinthu kapena chisindikizo cha kutentha chosungiramo zinthu zozizira umawonekera pazochitika za dew, zimasonyeza kuti chisindikizocho sichili cholimba. Kuphatikiza apo, kutsegula ndi kutseka pafupipafupi chitseko cha nyumba yosungiramo zinthu kapena anthu ambiri kulowa limodzi mu nyumba yosungiramo zinthu kudzawonjezera kutayika kwa kuzizira kwa nyumba yosungiramo zinthu. Muyenera kuyesetsa kupewa kutsegula chitseko kuti mupewe mpweya wotentha wambiri kulowa m'nyumba yosungiramo zinthu. Zachidziwikire, nyumba yosungiramo zinthu nthawi zambiri kapena kulowa m'sitolo ndi yayikulu kwambiri, kutentha kumawonjezeka kwambiri, kuti kuzizire mpaka kutentha komwe kwatchulidwa nthawi zambiri kumafunika nthawi yayitali.
3, valavu yotsekereza yoyendetsedwa molakwika kapena yotsekeka, kayendedwe ka refrigerant ndi kakang'ono kwambiri kapena kakang'ono kwambiri
Valavu yotsekereza mpweya ikasayendetsedwa bwino kapena kutsekedwa, imakhudza mwachindunji kayendedwe ka refrigerant kulowa mu evaporator. Valavu yotsekereza mpweya ikatsegulidwa kwambiri, kayendedwe ka refrigerant kamakhala kakakulu, kuthamanga kwa evaporative ndi kutentha kwa evaporative kumakweranso, kutentha kwa nyumba yosungiramo katundu kumachedwetsa liwiro la kuchepa kwa mpweya; nthawi yomweyo, pamene valavu yotsekereza mpweya imatsegulidwa pang'ono kwambiri kapena yotsekeka, kayendedwe ka refrigerant kamachepanso, mphamvu ya refrigerant ya makinawo imachepanso, kutentha kwa nyumba yosungiramo katundu kumachedwetsa liwiro lomwelo la kuchepa kwa mpweya.
Kawirikawiri poyang'ana mphamvu ya evaporation, kutentha kwa evaporation ndi frost ya pokoka kuti mudziwe ngati throttle refrigerant ikuyenda bwino. Kutsekeka kwa throttle ndi chinthu chofunikira chomwe chimakhudza kuyenda kwa refrigerant, zomwe zimapangitsa kuti throttle itseke ndiye chifukwa chachikulu cha ayezi ndi pulagi yodetsedwa.
Kutsekeka kwa ayezi kumachitika chifukwa chakuti chowumitsira sichili bwino, mufiriji muli madzi, madzi amalowa mu valavu yotsekereza, kutentha kumatsika kufika pansi pa 0 ℃, chinyezi mufiriji chimalowa mu ayezi ndikutseka dzenje la throttle; kutsekeka kodetsedwa kumachitika chifukwa cha maukonde a fyuluta yolowera mu throttle valve pamene dothi lambiri likulowa, madzi oyenda mufiriji sakuyenda bwino, ndipo kutsekekako kumapangidwa.
4, mphamvu ya compressor yoziziritsa ndi yochepa, mphamvu ya firiji siyingakwaniritse zofunikira pa katundu wosungiramo katundu
Compressor yoziziritsa chifukwa cha kugwira ntchito kwa nthawi yayitali, mphete ya silinda ndi piston ndi zinthu zina chifukwa cha kuwonongeka kwakukulu, ndi kutseguka kwakukulu, magwiridwe antchito otsekereza adzachepa moyenerera, coefficient ya mpweya wotumizira compressor yoziziritsanso imachepa, mphamvu yoziziritsira idzachepa. Ngati mphamvu yoziziritsira ili yochepa kuposa mphamvu ya kutentha ya nyumba yosungiramo katundu, izi zipangitsa kuti kutentha kwa nyumba yosungiramo katundu kuchepe pang'onopang'ono.
Compressor imatha kuwonedwa kudzera mu mphamvu ya compressor yoyamwa ndi kutulutsa mpweya, zomwe zimatsimikizira mphamvu ya compressor yoziziritsira. Ngati mphamvu ya compressor yoziziritsira mpweya yatsika, njira yodziwika bwino ndiyo kusintha compressor silinda liner ndi piston ring, ngati kusintha sikukugwira ntchito, iyenera kuganizira zinthu zina, komanso kuchotsa makina okonzanso, ndi kuthetsa mavuto.
5, evaporator pamaso pa mpweya wambiri kapena mafuta oziziritsa, kutentha kusamutsa zotsatira kunachepa
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, kutentha kwa chipinda chosungirako kuti kuchepe kuchepa kwa liwiro. Chifukwa chake, pakugwira ntchito ndi kukonza tsiku ndi tsiku, chisamaliro chiyenera kuperekedwa pakuchotsa mafuta pamwamba pa chubu chotenthetsera kutentha cha evaporator panthawi yake ndikutulutsa mpweya mu evaporator, kuti chiwongolere mphamvu yosamutsa kutentha ya evaporator.
6, kuchuluka kwa refrigerant mu dongosolo sikokwanira, mphamvu yosungiramo firiji sikokwanira
Kusakwanira kwa kayendedwe ka refrigerant kumachitika makamaka chifukwa cha zifukwa ziwiri, chimodzi ndi chakuti refrigerant sichikwanira, pakadali pano, ndikofunikira kokha kuti mubwezeretse kuchuluka konse kwa refrigerant. Chifukwa china ndi chakuti kutayikira kwa refrigerant m'dongosolo ndi kwakukulu, pankhaniyi, choyamba muyenera kupeza malo otayikira, kuyang'ana kwambiri kuyendera payipi, kulumikizana kwa valavu, kupeza malo otayikira, kenako ndikulipiritsa kuchuluka konse kwa refrigerant.
