Ukunqamula kwesiqandisi se-compressor lokushisa lokushisa kubhekisele e-valve eqophayo emazingeni okushisa esiqandisi, ukuze kuqinisekiswe ukusebenza okuphephile kwe-compressor, izinhlinzeko zokushisa kwe-R12 ukuqeda amandla okushisa akwazi ukwedlula i-130℃, Izinhlelo ezingama-R22 ne-ammonia azikwazi ukwedlula ezingama-50℃. Amazinga okushisa aphezulu aphezulu kakhulu, okuzodala ukuthi uwoyela wokuthambisa ukunciphisa i-viscosity ngenxa yokwanda kwezinga lokushisa, futhi wenze umphumela wokuthambisa ube mpofu, okuzobangela kalula izingxenye ezisebenzayo. Lapho izinga lokushisa eliphuma ngaphandle likhuphuka liseduze nephuzu lokuthambekela kokuthambisa, akulula ukuba yingozi, futhi izinga lokushisa eliqeda amandla liphakeme kakhulu kunamazinga okushisa avumelanayo.
Ukushisa kwekhabethe okubandayo kuphakeme emacaleni amabili: Okokuqala, i-fluage yokuvuza okuqandayo futhi akukho khabethe elibandayo elibandayo lase lisebenza, kepha izinga lokushisa ngaphakathi kwekhabethe alikwazi ukwehliswa. Kude kakhulu, ukulahlekelwa kokudla ngaphakathi kwekhabethe kubucayi, sicela uyilungise ngesikhathi sangempela kuzoba. Njengokujwayelekile, akuyona nje i-freezer entsha, kepha imvamisa egumbini elibandayo lesithwathwa ukukunikeza lo muzwa uhlala uhamba kancane. Enye ingxenye iyiqhwa likhululekile futhi likhulu ohlangothini lwesithwathwa. I-freezer ayikaze ifake isikhathi eside. Ngalesi sikhathi, kungahle kube namaphoyinti ambalwa wamanzi we-bulb avezwa, izinga lokushisa ngaphakathi kweKhabhinethi liphezulu.
I-freezer enjalo imvamisa kunzima ukuyilungisa. Kunzima ukuthola ukuvuza isikhathi eside ngemuva kokulungiswa ngoba kunzima ukuthola ukuvuza. Imbangela yesibili yokushisa okuphezulu iyisithwathwa se-evaporator, lesi simo ikakhulukazi sabakhulula umoya, lolu hlobo lwefriji ludinga i-evaporator, uma kungenjalo ukulahleka kwesithwathwa kulo mkhumbi, kuzovimba ukuhamba komoya. Amakhaza ngeke akhishwe futhi i-freezer ayikwazi ukusethwa. Lesi simo singase sibe khona ngenxa yenkinga ngohlelo lwe-defrost noma ngoba isikhathi se-defrost sinephutha noma ishubhu lokushisa lilimele.
1. I-compressor ngeke iqale
Uma kungekho mandla efrijini futhi ukukhanya kwenkomba yangaphakathi kungavulwa, khona-ke ungavala umnyango wefriji. Uma i-freezer imemezela ukuthi kukhona amandla, uma ukukhanya kungakukhanyisi, hlola ukuthi amandla amakhulu akhona bese uqiniseka ukuthi i-fuse yefritha akuyona yonke ifriji. Ingabe kunenkinga ngokuxhumana kwe-thermostat?
2 Lapho i-Overheat Shield isebenza, kufanele ulinde isikhashana ukuthi izinga lokushisa le-compressors liqale ukulahla.
3. Inkinga yenzeka ngoba i-thermostat ayikwazi ukusetha kabusha, ngoba oxhumana nabo bangene komunye nomunye futhi abakwazi ukuhlukaniswa.
3. Isithwathwa ngaphakathi kwefriji sikhulu kakhulu futhi ukumelana okushisayo kukhulu, okuthinta ukufakwa komoya obandayo.
I-4, i-freezer ayifakwanga kahle noma iqoqwe umlotha we-cowerser likhulu kakhulu, ngaleyo ndlela lithinta ukushiyeka kokushisa okushisa.
I-5, icala lohlelo lwefriji liningi kakhulu, umthwalo we-compressor Work esindayo, i-condenser iyashisa ohlangothini olungaphezulu, uhlangothi olungaphansi lusondele ekushiseni kwegumbi. Ukukhokhiswa okuqakathekile kakhulu okubangelwa i-evaporator akunakuhwaliswa ngokuphelele, okuholele ekutholeni amandla okupholisa i-evaporator, uma inqubo yenqubo exhunywe ekhefini yetafula lokucindezela, ingcindezi ephansi ingatholwa ngenhla kwenani elijwayelekile.
Isiqandisi sokuqapha i-compressor succer lokushisa liwukushisa kwesiqandisi esiqandisini e-halve ye-inhalation. Ukuze uqinisekise ukusebenza okuphephile kwe-compressor, ukuvikela i-liquid cysender shock ntomenon. Izinga lokushisa lokuvumelanisa kufanele libe liphakeme kancane kunamazinga okushisa okuhwamuka, okusho ukuthi igesi esiqandisini iba yigesi ebabazekayo, ngezinga elithile le-superheat. Ngokuvamile, akukho subcooler yegesi-ketshezi.
Kuhlelo lwe-Refider Freon, izinga lokushisa legesi kufanele libe yi-5℃ephakeme kunamazinga okushisa okuhwamuka, kanye ne-superheat superheat degree kufanelekile. Kudivayisi ye-ammonia isiqandisi, i-superheat degree ngokuvamile ingu-5 ~ 10℃, I-SuperHatEat degree emikhulu kakhulu noma incane kakhulu kufanele igwenywe, uma isilinganiso se-superheat sikhulu kakhulu, kuzokwenza ukuthi umthamo wefriji wehlise, uma isilinganiso samandla sikhuphuka, uma i-Superheat degree incane kakhulu, kulula ukukhiqiza i-liquid cylider pernomenon.
