Xa ubushushu bokufuma kwenkqubo yokugcina ifriji ebandayo buphantsi kwe-0 ° C, kuya kuvela umaleko weqhwa phezu komphezulu we-evaporator, nto leyo echaphazela ukusebenza kakuhle kokudlulisa ubushushu. Ke ngoko, ukunyibilikisa rhoqo kukwayinxalenye ebaluleke kakhulu yokugcina ifriji ebandayo. Zininzi iindlela zokunyibilikisa. Okwangoku, abavelisi bokwakha ifriji basebenzisa kakhulu iindlela ezintlanu: ukunyibilikisa okwenziweyo, ukunyibilikisa ngombane, ukunyibilikisa umoya oshushu, ukunyibilikisa amanzi, ukunyibilikisa amanzi emoyeni oshushu.
1. Ukunyibilikisa ngesandla kukususa ngesandla umaleko weqhwa kumphezulu wetyhubhu yokukhupha i-evaporator. Le ndlela ingenziwa ngaphandle kokumisa izixhobo zokukhenkceza. Le ndlela ithatha ixesha kwaye inzima, kwaye isiphumo sokunyibilikisa asilunganga.
2. Ukunyibilikisa umbane kukufaka isifudumezi sombane kwi-evaporator ukuze sinyibilikise ngobushushu bombane. Ngexesha lokunyibilikisa umbane, yima i-compressor okanye uyeke ukunika ulwelo kwi-evaporator. Ukunyibilikisa umbane kuneenzuzo zexabiso eliphantsi kunye nolawulo olulula, kodwa iindleko zokusebenza ziphezulu. Ngokuqhelekileyo isetyenziselwa ukunyibilikisa izixhobo zokugcina ubushushu, kungekhona ukunyibilikisa izixhobo zokugcina ubushushu. Kumaqondo obushushu ahlukeneyo, iimfuno zezakhono zokukhusela kufuneka zahluke, kwaye amandla okupholisa afunekayo nawo kufuneka ahluke. Ukusekwa kwendawo yokugcina ubushushu kufuneka kwenziwe ngokwezifiso ngokwemeko-bume yokusetyenziswa komthengi kunye nokusetyenziswa kwayo, ngaphandle kokuba akukho mfuneko ikhethekileyo yokulandela indlela yokulinganisa.
3. Ukunyibilikisa igesi eshushu kukusebenzisa umphunga wefriji oshushu kakhulu okhutshwa yicompressor ukukhulula ubushushu kwi-evaporator nokunyibilikisa umaleko weqhwa kumphezulu we-evaporator. Inkqubo yokunyibilikisa igesi eshushu iyinkimbinkimbi kwaye ixabiso liphezulu. Kodwa isiphumo sokunyibilikisa singcono. Xa isetyenziswa kwinkqubo ye-ammonia, ioyile eqokelelene kwi-evaporator inokukhutshwa kwi-drain okanye kwi-reservoir yoxinzelelo oluphantsi. Kwinkqubo yokunyibilikisa igesi eshushu, uxinzelelo lulawulwa ngokubanzi kwi-0.6MPa. Zama ukusebenzisa igesi enoxinzelelo oluphezulu ekhutshwa kwi-compressor yesigaba esinye ukunyibilikisa. Ubusika bunokufaneleka ukunciphisa amanzi okupholisa okanye ukunciphisa inani lee-condenser, ukwandisa ubushushu bokukhupha, ukunciphisa ixesha lokunyibilikisa. Kwiinkqubo ze-ammonia, i-ammonia eshushu yokunyibilikisa kufuneka iqhagamshelwe kumbhobho wokukhupha we-oyile yokwahlulahlula.
4. Ukunyibilikisa amanzi kukutshiza amanzi kumphezulu we-evaporator ngesixhobo sokutshiza ukuze kunyibilikise umaleko weqabaka. Inkqubo yokunyibilikisa amanzi inesakhiwo esintsonkothileyo kunye neendleko eziphezulu, kodwa isiphumo esihle kunye neendleko eziphantsi. Ukunyibilikisa amanzi kunokususa kuphela umaleko weqabaka kumphezulu wangaphandle we-evaporator, kwaye akunakusombulula isiphumo esibi sokuqokelelwa kweoyile kwi-evaporator ekudlulisweni kobushushu. Eyona nto ibalulekileyo yibhodi yokugcina ebandayo, edla ngokuveliswa kwangaphambili ngumenzi webhodi yokugcina ebandayo kwaye inobude obumiselweyo, ububanzi kunye nobukhulu obumiselweyo. Ibhodi yokugcina ebandayo enobukhulu obuyi-100mm idla ngokusetyenziselwa ukugcina ebandayo kubushushu obuphezulu nobuphakathi, ibhodi yokugcina ebandayo enobukhulu obuyi-120mm okanye obuyi-150mm idla ngokusetyenziselwa ukugcina ebandayo kubushushu obuphantsi kunye nokugcina ebandayo.
5. Ukunyibilikisa amanzi omoya oshushu ziindlela ezimbini zokunyibilikisa ashushu kunye nokunyibilikisa amanzi ezisetyenziswa ngaxeshanye, ezigxininisa iingenelo zazo zombini, kwaye zinokususa ngokukhawuleza nangokufanelekileyo umaleko weqhwa kumphezulu we-evaporator kwaye zisuse ukuqokelelwa kweoyile ngaphakathi kwe-evaporator. Xa inyibilikisa, igesi eshushu ithunyelwa kuqala kwi-evaporator ukuze yahlule umaleko weqhwa kumphezulu we-evaporator, aze emva koko amanzi atshizwe ukuze ahlambe ngokukhawuleza umaleko weqhwa. Emva kokuba unikezelo lwamanzi lunqunyulwe, umphezulu we-evaporator "womiswa" ngumoya oshushu ukuthintela ifilimu yamanzi angaphezulu ukuba ingabi shushu kwaye ichaphazele ukudluliselwa kobushushu. Ngaphambili, abavelisi beebhodi zokugcina izinto ezibandayo babesebenzisa kakhulu i-polyethylene kunye ne-polystyrene njengezinto zokwakha. Ngoku kukho ukusebenza okungcono kwebhodi yesandwich ye-polyurethane. Uxinano lwezinto zokugquma ze-polystyrene foam luphantsi, alunakufakwa kwi-insulation. Zihlala zisetyenziswa kwizixhobo ezikhethekileyo. I-Polyethylene yinto elungileyo eluhlaza. Ngomlinganiselo othile, inokukhutshwa nge-foam ngaphandle koxinano olufanelekileyo, isiphumo sokugquma silungile, amandla okuthwala aqinileyo ezinto zokugquma. Ipleyiti yepolyurethane ingcono, inomsebenzi ongcono wokukhusela kwaye ayifunxi umswakama, kodwa eli xabiso lokugcina izinto liphezulu kancinci.
