I-condenser isebenza ngokudlulisa igesi ngetyhubhu ende (ehlala idityaniswe kwi-solenoid), ivumela ubushushu ukuba buphume bungene emoyeni ojikelezileyo. Iintsimbi ezifana nobhedu ziqhuba ubushushu kakuhle kwaye zihlala zisetyenziselwa ukuthutha umphunga. Ukuze kuphuculwe ukusebenza kakuhle kwe-condenser, izinki zobushushu ezinentsebenzo entle yokuqhuba ubushushu zihlala zongezwa kwimibhobho ukuze kwandiswe indawo yokusasaza ubushushu ukuze kukhawuleziswe ukusasaza ubushushu, kwaye i-convection yomoya ikhawuleziswa yifeni ukuze isuse ubushushu. Umgaqo wokuphola wefriji jikelele kukuba i-compressor icinezele i-medium esebenzayo ukusuka kubushushu obuphantsi kunye negesi yoxinzelelo oluphantsi ukuya kubushushu obuphezulu kunye negesi yoxinzelelo oluphezulu, ize emva koko inyibilike ibe lulwelo oluphakathi kunye noxinzelelo oluphezulu nge-condenser. Emva kokuba i-throttle valve ipholishiwe, iba lulwelo oluphantsi kunye noxinzelelo oluphantsi. I-medium yokusebenza yolwelo oluphantsi kunye noxinzelelo oluphantsi ithunyelwa kwi-evaporator, apho i-evaporator ifunxa ubushushu kwaye iphume iye kubushushu obuphantsi kunye noxinzelelo oluphantsi, ethunyelwa kwi-compressor kwakhona, ngaloo ndlela igqibezela umjikelo wokuphola. Inkqubo yokuphola yoxinzelelo lomphunga enesigaba esinye yenziwe ngezinto ezine ezisisiseko: i-compressor yokuphola, i-condenser, i-throttle valve kunye ne-evaporator. Ziqhagamshelwa ngokulandelelanayo ngemibhobho ukwenza inkqubo evaliweyo. I-refrigerant ijikeleza rhoqo kwinkqubo, itshintsha imeko yayo kwaye itshintshiselana ubushushu nehlabathi langaphandle.
