Umshini{0}okuqandayo osheshayo uyithuluzi lemboni elehlisa ngokushesha izinga lokushisa lokudla libe ngaphansi kwezingaqhwa, okulenze lidlule endaweni enkulu yokwakheka kwekristalu yeqhwa ngesikhathi esifushane, ngaleyo ndlela kugcinwe ikhwalithi yokudla. Umgomo wayo wokusebenza usekelwe ngokuyinhloko ekuqhutshweni kokushisa nokudlulisa ukushisa kwe-convection. Okokuqala, ukudla kufakwa ebhandeni lokuthutha futhi kungena{3}}endaweni yezinga lokushisa eliphansi-lomshini wokuqandisa osheshayo. Ngaphakathi emshinini, isistimu yesiqandisi (evame ukusebenzisa i-ammonia noma i-Freon njengesiqandisi) ikhiqiza umoya obandayo. Lo moya obandayo uphoqeleka ukuba ujikelezwe yisiphephetha-moya, ushintshanisa ukushisa nendawo yokudla futhi ususe ukushisa ngokushesha.
Izinga lokushisa lomshini osheshayo-wokuqandisa ngokuvamile lilawulwa phakathi -no-30℃kanye -no-120℃, kuye ngohlobo lokudla kanye nezidingo ezisheshayo-zeqhwa. Isikhathi esisheshayo{11}sokuqandisa ngokuvamile siyimizuzu engu-10-25, okuqinisekisa ukuthi izinga lokushisa eliyisisekelo lokudla lehla ngokushesha ngaphansi -ku-18℃, okuvimba ngempumelelo umsebenzi we-microbial nokwelula impilo yeshalofu. Izingxenye ezibalulekile zomshini{14}}okuqandayo osheshayo zifaka i-compressor yesiqandisi, i-evaporator, i-condenser, ifeni, nesistimu yokulawula. I-evaporator imunca ukushisa okuvela ekudleni, i-compressor yesiqandisi iminyanisa{15}}izinga lokushisa eliphansi, eliphansi{16}}lokucindezela igesi efrijini libe{17}}eliphezulu{17}}gesi elinomfutho ophezulu, futhi i-condenser ipholisa izinga lokushisa eliphezulu, i-high-pressure gas ibe uketshezi olunomfutho ophezulu wokucindezela.
