Umatshini okhawulezayo{{0} wokukhenkcisa sisixhobo semizi-mveliso esehlisa ngokukhawuleza iqondo lobushushu lokutya ukuya ngaphantsi kweqondo lomkhenkce, nto leyo ebangela ukuba kudlule kwindawo enkulu yokwakheka kwekristale yomkhenkce ngexeshana elifutshane, oko kugcina umgangatho wokutya. Umgaqo wayo wokusebenza usekelwe ngokukodwa ekuqhubeni ukushisa kunye nokuhanjiswa kobushushu be-convection. Okokuqala, ukutya kubekwa kwibhanti yokuhambisa kwaye kungena kwindawo ephantsi{3}}yobushushu obuphantsi{4}kumatshini wokukhenkceza. Ngaphakathi komtshini, inkqubo yefriji (edla ngokusetyenziswa i-ammonia okanye iFreon njengefriji) ivelisa umoya obandayo. Lo moya ubandayo unyanzelekile ukuba ujikelezwe yi-fan, utshintshise ubushushu kunye nomphezulu wokutya kunye nokususa ubushushu ngokukhawuleza.
Ubushushu bomatshini okhawulezayo-womatshini wokukhenkceza uvamise ukulawulwa phakathi kwe -30℃kunye ne -120℃, ngokuxhomekeke kudidi lokutya kunye neemfuno ezikhawulezayo zomkhenkce{9}. Ixesha elikhawulezayo -lomkhenkce lidla ngokuba yi-10-imizuzu engama-25, iqinisekisa ukuba ubushushu bokutya bukhawuleza behle ngaphantsi -kuthintele ukusebenza kwe-microbial kunye nokwandisa ubomi beshelufu. Amalungu aphambili omatshini{14}}onomkhenkce okhawulezayo aquka isicompressor sesikhenkcisi, i-evaporator, i-condenser, ifeni, kunye nenkqubo yokulawula. I-evaporator ifunxa ubushushu ekutyeni, icompressor yefriji icinezela ubushushu obuphantsi,{15}ophantsi{16}}noxinzelelo lwegesi epholileyo kwiqondo eliphezulu{17}}lobushushu obuphezulu, igesi yoxinzelelo oluphezulu, kunye ne-condenser ipholisa ubushushu obuphezulu, igesi yoxinzelelo oluphezulu ibe kulwelo loxinzelelo oluphezulu lwefriji.
