1. Chipale chofewa pamwamba pa chotenthetsera choziziritsira ndi chokhuthala kwambiri kapena pali fumbi lochuluka, ndipo mphamvu yosamutsa kutentha imachepa
Chifukwa china chofunikira chomwe chimapangitsa kuti kutentha kosungirako kuchepe pang'onopang'ono ndi mphamvu yochepa yotumizira kutentha kwa evaporator, yomwe imachitika makamaka chifukwa cha chisanu chokhuthala kapena kuchuluka kwa fumbi pamwamba pa evaporator. Popeza kutentha kwa pamwamba pa evaporator mufiriji yosungiramo yozizira kumakhala kotsika kuposa 0 ℃, ndipo chinyezi m'nyumba yosungiramo zinthu ndi chapamwamba, chinyezi chomwe chili mumlengalenga chimazizira mosavuta kapena kuzizira pamwamba pa evaporator, zomwe zimakhudza momwe evaporator imasamutsira kutentha. Pofuna kupewa chisanu cha pamwamba pa evaporator kuti chisakhale chokhuthala kwambiri, chiyenera kusungunuka nthawi zonse. Njira ziwiri zosavuta zosungunula zikupezeka pansipa: ① Siyani kusungunuka. Ndiye kuti, siyani kugwira ntchito kwa compressor, tsegulani chitseko cha nyumba yosungiramo zinthu, lolani kutentha kwa nyumba yosungiramo zinthu kukwere, ndikuyambitsanso compressor pambuyo poti chisanu chasungunuka chokha. ② Tsukani kirimu. Mukachotsa katundu m'nyumba yosungiramo zinthu, tsukani mwachindunji pamwamba pa chitoliro cha evaporator ndi madzi apampopi ndi kutentha kwakukulu kuti musungunuke kapena kugwa kuchokera pa chisanu. Kuwonjezera pa kusamutsa kutentha kwa evaporator chifukwa cha chisanu chokhuthala, mphamvu yosamutsa kutentha ya evaporator idzachepa kwambiri chifukwa cha kuchuluka kwa fumbi pamwamba pa evaporator chifukwa sinatsukidwe kwa nthawi yayitali.
2. Chifukwa cha kutenthetsa kosakwanira kapena kutseka bwino, malo osungiramo zinthu zozizira m'firiji amataya mphamvu zambiri zoziziritsira
Kusagwira bwino ntchito kwa kutentha chifukwa cha kukhuthala kosakwanira kwa gawo lotetezera kutentha la mapaipi ndi makoma otetezera kutentha a nyumba yosungiramo zinthu, komanso kutsika kwa kutentha ndi kutenthetsa kutentha. Izi zimachitika makamaka chifukwa cha kusasankha bwino makulidwe a gawo lotetezera kutentha panthawi yokonza kapena khalidwe loipa la zipangizo zotetezera kutentha panthawi yomanga. Kuphatikiza apo, pomanga ndi kugwiritsa ntchito, kutenthetsa kutentha ndi kusasunthika kwa chinyezi kwa zinthu zotetezera kutentha kumatha kuwonongeka, zomwe zimapangitsa kuti gawo lotetezera kutentha likhale lonyowa, losasinthika, kapena lowonongeka. Chifukwa china chofunikira cha kutayika kwakukulu kwa kuzizira ndi kusagwira bwino ntchito kwa nyumba yosungiramo zinthu, ndipo mpweya wotentha wambiri umalowa m'nyumba yosungiramo zinthu chifukwa cha kutuluka kwa madzi. Nthawi zambiri, ngati pali kuzizira pa mzere wotsekera chitseko cha nyumba yosungiramo zinthu kapena kutsekedwa kwa khoma lotetezera kutentha lozizira, zikutanthauza kuti kutseka sikuli kolimba. Kuphatikiza apo, kutsegula ndi kutseka pafupipafupi chitseko cha nyumba yosungiramo zinthu kapena anthu ambiri olowa m'nyumba yosungiramo zinthu pamodzi kudzawonjezera kutayika kwa mphamvu yozizira m'nyumba yosungiramo zinthu. Pewani kutsegula chitseko cha nyumba yosungiramo zinthu momwe mungathere kuti mupewe mpweya wotentha wambiri kulowa m'nyumba yosungiramo zinthu. Zachidziwikire, ngati nyumba yosungiramo zinthu nthawi zambiri imakhala ndi zinthu zambiri kapena katunduyo ndi wamkulu kwambiri, kutentha kumawonjezeka kwambiri, ndipo nthawi zambiri zimatenga nthawi yayitali kuti zizizire mpaka kutentha komwe kwatchulidwa.
3. Valavu yolumikizira throttle imasinthidwa kapena kutsekedwa molakwika, ndipo madzi otulutsira mufiriji ndi akulu kwambiri kapena ang'onoang'ono kwambiri
Kusintha kosayenera kapena kutsekeka kwa valavu yotsekeka kumakhudza mwachindunji kuyenda kwa valavu yoziziritsira mu evaporator. Pamene valavu yotsekeka yatsegulidwa yayikulu kwambiri, kuchuluka kwa madzi mu refrigerant kumakhala kwakukulu kwambiri, kuthamanga kwa madzi mu evaporator ndi kutentha kwa madzi mu evaporator kudzawonjezekanso, ndipo kutentha kwa nyumba yosungiramo katundu kudzachepa; nthawi yomweyo, valavu yotsekeka ikatsegulidwa yaying'ono kwambiri kapena yotsekedwa, kuchuluka kwa madzi mu refrigerant kumachepanso, mphamvu yozizira ya dongosolo imachepanso, ndipo kutentha kwa madzi mu refrigerant kudzachepanso. Nthawi zambiri, zitha kuweruzidwa ngati kuchuluka kwa madzi mu refrigerant mu valavu yotsekeka ndikoyenera poona kuthamanga kwa madzi mu evaporator, kutentha kwa madzi mu evaporator komanso momwe chitoliro chokokera madzi chikukhalira. Kutsekeka kwa valavu yotsekeka ndi chinthu chofunikira chomwe chimakhudza kuyenda kwa refrigerant. Zifukwa zazikulu zomwe valavu yotsekeka ya valavu yotsekeka ndi kutsekeka kwa ayezi ndi kutsekeka kwauve. Kutsekeka kwa ayezi kumachitika chifukwa cha kuuma koyipa kwa chowumitsira, ndipo refrigerant ili ndi chinyezi. Ikadutsa mu valavu ya throttle, kutentha kumatsika pansi pa 0 °C, ndipo chinyezi chomwe chili mufiriji chimaundana kukhala ayezi ndikutseka dzenje la valavu ya throttle; kutsekeka kodetsedwa kumachitika Chifukwa cha kuchuluka kwa dothi pa sikirini ya fyuluta pamalo olowera valavu ya throttle, kuyenda kwa refrigerant sikosalala, zomwe zimapangitsa kuti itseke.
4. Kugwira ntchito bwino kwa compressor yoziziritsira ndi kochepa, ndipo mphamvu yoziziritsira singathe kukwaniritsa zofunikira zonyamula katundu m'nyumba yosungiramo katundu
Chifukwa cha ntchito ya nthawi yayitali ya compressor yoziziritsira, silinda ndi mphete ya piston ndi zinthu zina zimawonongeka kwambiri, ndipo malo ofanana amawonjezeka, magwiridwe antchito otsekereza amachepa moyenerera, mphamvu yotumizira mpweya ya compressor yoziziritsira imachepanso, ndipo mphamvu yoziziritsira imachepa. Pamene mphamvu yoziziritsira ili yochepa kuposa mphamvu yotenthetsera ya nyumba yosungiramo katundu, kutentha kwa nyumba yosungiramo katundu kumatsika pang'onopang'ono. Mphamvu yoziziritsira ya compressor imatha kuweruzidwa mwachidwi poona mphamvu zokoka ndi kutulutsa kwa compressor. Ngati mphamvu yoziziritsira ya compressor imachepa, njira yomwe imagwiritsidwa ntchito kwambiri ndikusintha silinda ndi mphete ya piston ya compressor. Ngati kusintha sikukugwirabe ntchito, zinthu zina ziyenera kuganiziridwa, kapena ngakhale kugwetsa ndi kukonzanso, ndi kuthetsa mavuto.
5. Mu evaporator mumakhala mpweya wambiri kapena mafuta oziziritsa, ndipo mphamvu yosamutsa kutentha imachepa.
Mafuta oziziritsira akangolumikizidwanso mkati mwa chubu chotenthetsera kutentha cha evaporator, mphamvu yake yosamutsira kutentha idzachepa. Mofananamo, ngati pali mpweya wochulukirapo mu chubu chotenthetsera kutentha, malo osamutsira kutentha a evaporator adzachepa, ndipo kusamutsira kutentha kudzachepa. Kugwira ntchito bwino kudzachepanso kwambiri, ndipo kutentha kwa nyumba yosungiramo katundu kudzachepa. Chifukwa chake, pakugwira ntchito ndi kukonza tsiku ndi tsiku, chisamaliro chiyenera kuperekedwa pakuchotsa madontho a mafuta mkati mwa chubu chotenthetsera kutentha cha evaporator ndikutulutsa mpweya mu evaporator kuti evaporator igwire bwino ntchito.
6. Kuchuluka kwa refrigerant mu dongosolo sikokwanira, ndipo mphamvu yoziziritsira sikokwanira
Pali zifukwa ziwiri zazikulu zomwe zimapangitsa kuti refrigerant isayende bwino. Choyamba, mphamvu ya refrigerant si yokwanira. Pakadali pano, refrigerant yokha ndiyofunika kuiwonjezera. Chifukwa china n'chakuti pali kutayikira kwa refrigerant m'dongosolo. Pankhaniyi, choyamba muyenera kupeza malo otayikira, kuyang'ana kwambiri kulumikizana kwa payipi iliyonse ndi valavu, kenako mudzaze refrigerant yokwanira mukakonza ziwalo zomwe zatayikira.
