Chitoliro dongosolo kamangidwe amatanthauza kamangidwe ka refrigerant kompresa ndi zosiyanasiyana zipangizo firiji, zigawo zikuluzikulu olumikizidwa pamodzi kupanga dongosolo wololera kuzirala, kuphatikizapo m'mimba mwake anatsimikiza, mipope kutentha ndi zovekera ndi masanjidwe chitoliro.Kukonzekera kozizira kosungirako kozizira ndikwabwino kapena koipa, kaya kokhudzana ndi firiji kumakhala ndi ntchito yabwino yozizira, ntchito yokhazikika komanso yotetezeka imagwirizananso ndi digiri ya kusungirako kuzizira kosavuta kukhazikitsa ndikuyika ntchito ya chitoliro cha utsi.

Cholinga cha mapangidwe ozizira posungira mapaipi ndikuwonetsetsa kuti evaporator ikhoza kukhala yokwanira kuchuluka kwamadzimadzi, kudziwa kutalika kwa gawo lililonse la payipi, ndikufupikitsa kutalika kwa mapaipi a payipi ya firiji, kupewa kupanikizika kwambiri. imfa, kotero ozizira oyika dongosolo ndi chuma chabwino, komanso kupewa madzi kugunda ndi mapaipi kachitidwe firiji kompresa mafuta chiwembu.

Chotsatira chachikulu cha mapangidwe a mapaipi ndi zinthu ziwiri: kutsika kwapakati ndi kuthamanga kwa chitoliro.Refrigerant kuthamanga kutsika mu payipi kumachepetsa kuziziritsa ndikuwonjezera kugwiritsa ntchito mphamvu, kutsika kwamphamvu kwamphamvu, motero kuyenera kupewa kutsika kwambiri.Kawirikawiri kuthamanga kutsika mu chitoliro chamadzimadzi sichimakhudza mwachindunji mphamvu yoziziritsira, koma kuthamanga kwa madzi mu chitoliro chamadzimadzi kuonetsetsa kuti madzi amadzaza madzi asanalowe mu chipangizo chogwedeza, chitoliro chamadzimadzi chimayambitsa kuthamanga kwambiri mumtsinje wamadzimadzi. mu kung'anima nthunzi kupanga mphamvu pamaso throttling kung'anima nthunzi idzakhudza mwachindunji kulamulira ndi kuwongolera otaya chipangizo throttle, kuthamanga dontho.Kuchepetsa awiri a madzi chitoliro kuthamanga dontho ukuwonjezeka, zidzachititsa dongosolo kubaya refrigerant mlandu kuchuluka.Owonjezera refrigerant zidzakhudza kwambiri ulamuliro otaya refrigerant mu otsika mavuto mbali ya firiji dongosolo, lalikulu inertial zotsatira zingachititse madzi refrigerant mu refrigerant otaya kulamulira chipangizo kayendedwe matenda.Mu chitoliro cha utsi ndi chitoliro choyamwa cha evaporator chiyenera kukhala ndi kuthamanga kokwanira, chifukwa mafuta ndi nthunzi ya refrigerant sizimasakanikirana mosavuta, komanso kuchuluka kwa mpweya wa refrigerant ndikokwanira kunyamula mafuta a firiji akuyenda mozungulira mafuta ozungulira mu dongosolo. kugwira ntchito moyenera.
