Icinezelwe yicompressor, igesi yokuqala yefriji enobushushu obuphantsi noboxinzelelo oluphantsi icinezelwa ibe ngumphunga oshushu kakhulu nobushushu obuphezulu, ize ikhutshwe kumbhobho wokukhupha umoya wecompressor. Emva kokuba ifriji yegesi enobushushu obuphezulu noboxinzelelo oluphezulu ikhutshwe kumbhobho wokukhupha umoya wecompressor, ithunyelwa kwi-condenser ngevalvu ye-electromagnetic four-way. Igesi yefriji enobushushu obuphezulu noboxinzelelo oluphezulu ingena kwi-condenser, kwaye i-condenser ipholiswe yi-axial fan. I-refrigerant ekwipayipi iyapholiswa kwaye ithunyelwe njenge-refrigerant yolwelo enobushushu obuphakathi noboxinzelelo oluphezulu; emva kokuba i-refrigerant yolwelo enobushushu obuphakathi noboxinzelelo oluphezulu ithunyelwe nge-condenser, idlula kwi-valve yokujonga umbhobho, idlule kwi-filter eyomileyo, ize idlule kwi-valve yokwandisa ye-elektroniki ukuze ithontsize kwaye inciphise uxinzelelo. Ijika ibe lulwelo lwefriji oluphantsi noboxinzelelo oluphantsi, oluthi emva koko luthunyelwe kwimibhobho yeeyunithi zangaphakathi.
Umgaqo wokufudumeza ngokusisiseko ufana nalowo wokufrijisa, umahluko kukuba ibhloko yevalvu kwivalvu ye-electromagnetic four-way ilawulwa yinkqubo yesekethe ukutshintsha icala, ngaloo ndlela itshintsha icala lokuhamba kwefriji kwaye ifezekisa utshintsho ukusuka ekupholiseni ukuya ekufudumaleni.
Uhlalutyo lwecandelo ngalinye lemigca emininzi
I-Compressor (1): Intliziyo yenkqubo yokukhenkcisa, efunxa i-refrigerant yegesi enobushushu obuphantsi nobuphantsi kwaye ikhupha i-refrigerant yegesi enobushushu obuphezulu nobuphezulu. I-compressor ngamandla enkqubo yokukhenkcisa.

Ivalvu eneendlela ezine (9): Ivalvu eneendlela ezine inamacandelo amathathu: ivalvu yomqhubi, ivalvu ephambili kunye ne-solenoid coil. Iplagi yevalvu yasekhohlo okanye yasekunene iyavulwa kwaye ivalwe ngokuvula nokucima i-electromagnetic coil current, ukuze iityhubhu ze-capillary zasekhohlo nasekunene zisetyenziswe ukulawula uxinzelelo kumacala omabini omzimba wevalvu, ukuze isilayida emzimbeni wevalvu sityibilike ekhohlo nasekunene phantsi kwesenzo somahluko woxinzelelo ukutshintsha Icala lokuhamba kwefriji ukufezekisa injongo yokupholisa okanye yokufudumeza.
I-Condenser (10): I-condenser ngumphunga we-refrigerant obushushu obuphezulu noxinzelelo oluphezulu okhutshwa kwi-compressor yokupholisa, apho igesi ye-refrigerant ebushushu obuphezulu noxinzelelo oluphezulu ihlangana kwaye itshintshiselane ubushushu nomoya ngokunyanzeliswa kwe-convection.
Ifeni (11): Umsebenzi ophambili kukuqinisa ukudluliselwa kobushushu obuhambelanayo, ukwandisa isiphumo sokudluliselwa kobushushu, ukufunxa ubushushu kunye nokukhupha ukupholisa xa kuphola, kunye nokufunxa ukubanda kunye nokukhupha ubushushu xa kufudunyezwa.
Iphakheji yokubona ubushushu obuncibilikayo (12): Ilawula ubushushu bokuseta kwakhona bokuncibilika. Xa kufikwe kubushushu obumiselweyo bephakheji yokubona ubushushu, ukuncibilika kuya kuyeka. Kulawulo lokubona ukuncibilika
Ivalvu yokwandisa ye-elektroniki (13): Umsebenzi wevalvu yokwandisa ye-elektroniki kukugoba. Umahluko ophambili kwivalvu yokwandisa ubushushu be-capillary kukuba ixhomekeke kumlawuli ukulawula ukuvulwa. Ukuvulwa kwesango levalvu kunokulungiswa ngokweemfuno zokulawula ukuhamba. Ukusetyenziswa kwevalvu yokwandisa ye-elektroniki kunokwenza ummiselo wokuhamba uchaneke ngakumbi, kodwa ixabiso libiza kakhulu.
