Izinga lokushisa lokukhipha umoya le-compressor yesiqandisi libhekisela ku-valve yokukhipha umoya ekushiseni kwesiqandisi, ukuze kuqinisekiswe ukusebenza okuphephile kwe-compressor, izihlinzeko zokushisa kokukhipha umoya kwedivayisi ye-R12 azikwazi ukudlula u-130℃, R22 kanye nezinhlelo ze-ammonia azikwazi ukudlula ama-50℃. Izinga lokushisa lokukhipha umoya liphezulu kakhulu, okuzokwenza ukuthi uwoyela wokugcoba unciphise i-viscosity ngenxa yokwenyuka kwezinga lokushisa, futhi kwenze umphumela wokugcoba ube mubi, okuzokwenza kalula ukuthi izingxenye ezisebenzayo zonakale. Lapho izinga lokushisa lokukhipha umoya likhuphuka eduze nendawo yokukhanya yesithambisi, akulula ukuba yingozi, futhi izinga lokushisa lokukhipha umoya liphakeme kakhulu kunezinga lokushisa lokuvala umoya.
Izinga lokushisa lekhabhinethi elibandayo liphezulu ezimweni ezimbili: Okokuqala, i-fluorine evuzayo yesiqandisi kanye nekhabhinethi elibandayo elingasebenzi kahle, kodwa izinga lokushisa ngaphakathi kwekhabhinethi alikwazi ukuncishiswa. Isikhathi eside kakhulu, ukulahlekelwa ukudla ngaphakathi kwekhabhinethi kubi kakhulu, sicela ukulungise ngesikhathi sangempela kuzoba njalo. Njengokujwayelekile, akuyona nje i-freezer entsha, kodwa ngokuvamile egumbini elibandayo eliphakathi neqhwa ukukunikeza lo muzwa uhlala uhamba kancane kakhulu. Ingxenye yesibili ayinaqhwa futhi ijiyile ohlangothini lwesiqhwa. I-freezer ayikaqandi isikhathi eside. Ngalesi sikhathi, kungase kube namachashazi ambalwa ebhalbhu lamanzi alethwayo, izinga lokushisa ngaphakathi kwekhabhinethi liphezulu.
Ifriji elinjalo ngokuvamile linzima ukulilungisa. Kunzima ukuthola ukuvuza isikhathi eside ngemva kokulungiswa ngoba kunzima ukuthola ukuvuza. Imbangela yesibili yokushisa okuphezulu yiqhwa le-evaporator, lesi simo ikakhulukazi amafriji apholiswe ngomoya, lolu hlobo lwefriji ludinga i-evaporator, uma kungenjalo ukulahlekelwa yiqhwa kulo mhwamuko, luzovimba indlela yomoya. Umkhuhlane ngeke ukhishwe futhi ifriji ayikwazi ukuphola. Lesi simo singase sibangelwe inkinga ngohlelo lokuncibilikisa noma ngoba i-timer yokuncibilikisa inephutha noma ipayipi lokushisa lonakele.
1. I-compressor ngeke iqale
Uma kungekho mandla efrijini futhi isibani senkomba yangaphakathi singase sivuleke, ungawuvala umnyango wefriji. Uma ifriji limemezela ukuthi kukhona ugesi, uma isibani singakhanyi, hlola ukuthi ugesi oyinhloko uvuliwe yini bese uqinisekisa ukuthi i-fuse yefriji akuyona yonke ifriji. Ingabe kunenkinga ngokuxhumana kwe-thermostat?
2. I-compressor ingase ishe, i-motor coil ishe, futhi i-starter ingahlolwa. Uma isivikelo sokushisa ngokweqile sisebenza, kufanele ulinde isikhashana ukuze izinga lokushisa le-compressor liqale ukwehla.
3. Inkinga ivela ngoba i-thermostat ayikwazi ukusethwa kabusha, ngoba oxhumana nabo bahlangene futhi abakwazi ukuhlukaniswa.
3. Iqhwa elingaphakathi kwefriji likhulu kakhulu futhi ukumelana nokushisa kukhulu, okuthinta ukuqhutshwa komoya obandayo.
4, ifriji ayifakwanga kahle noma ukuqongelela komlotha we-condenser kukhulu kakhulu, ngaleyo ndlela kuthinte ukushabalaliswa kokushisa kwe-condenser.
5, ukushaja kwesistimu yokuqandisa kukhulu kakhulu, umthwalo womsebenzi we-compressor unzima, i-condenser ishisa ohlangothini olungaphezulu, uhlangothi olungezansi luseduze nokushisa kwegumbi. Ukushaja kwe-refrigerant kukhulu kakhulu okubangelwa ku-evaporator akukwazi ukuhwamuka ngokuphelele, okuholela ekwehleni kwamandla okupholisa e-evaporator, uma i-orifice yenqubo ixhunywe etafuleni lokucindezela isheke, ingcindezi ephansi ingatholakala ngaphezu kwenani elijwayelekile.
Izinga lokushisa lokumunca i-compressor yesiqandisi liyizinga lokushisa le-refrigerant ku-valve yokuphefumula. Ukuze kuqinisekiswe ukusebenza okuphephile kwe-compressor, kuvinjelwe isenzakalo sesilinda sokushaqeka koketshezi. Izinga lokushisa lokumunca kufanele libe phezulu kancane kunezinga lokushisa lokuhwamuka, okusho ukuthi igesi yesiqandisi iba yigesi eshisa kakhulu, enezinga elithile lokushisa okukhulu. Ngokuvamile, ayikho i-subcooler yegesi-uketshezi.
Kuhlelo lwe-Freon oluqandisiwe, izinga lokushisa legesi yokumunca kufanele libe ngu-5℃izinga lokushisa lokuhwamuka liphakeme kunezinga lokushisa lokuhwamuka, futhi izinga lokushisa eliphakeme legesi yokumunca liyafaneleka. Kwidivayisi yokuqandisa i-ammonia, izinga lokushisa eliphakeme lokumunca ngokuvamile lingu-5~10℃, izinga lokushisa okuphezulu lokumunca likhulu kakhulu noma lincane kakhulu kufanele ligwenywe, uma izinga lokushisa okuphezulu likhulu kakhulu, lizokwenza umthamo wokuqandisa wehle, izinga lokushisa lokukhipha umoya likhuphuke, ukusetshenziswa kwamandla kukhuphuke, uma izinga lokushisa okuphezulu lincane kakhulu, kulula ukukhiqiza isenzakalo sesilinda esishaywayo soketshezi.
Isikhathi sokuthunyelwe: Juni-12-2023
