Xa ubushushu bobushushu benkqubo yokugcinwa kwefriji ebandayo bungaphantsi kwe-0 ° C, iqabaka iya kuvela kumphezulu we-evaporator, echaphazela ukusebenza kakuhle kokudluliselwa kobushushu.Ngoko ke, ukuchithwa rhoqo kuyingxenye ebaluleke kakhulu yokugcina ukugcinwa okubandayo.Zininzi iindlela zokuyinyibilikisa.Okwangoku, abavelisi bokwakha indawo ebandayo basebenzisa iindlela ezintlanu kakhulu: ukutshitshiswa kwe-artificial, ukutshitshiswa kombane, ukutshitshiswa komoya oshushu, ukutshatyalaliswa kwamanzi, ukutshitshiswa kwamanzi ashushu.
1. I-Manual defrosting kukususa ngesandla umaleko weqabaka kumphezulu wetyhubhu yokukhupha i-evaporator.Le ndlela inokuqhutywa ngaphandle kokumisa izixhobo zefriji.Le ndlela ithatha ixesha kwaye inzima, kwaye umphumo wokunciphisa umbi.
2. Ukutshatyalaliswa kombane kukufakela isifudumezi sombane kwi-evaporator ukuze sincitshiswe ngokufudumeza kombane.Ngexesha lokunciphisa, yeka icompressor okanye uyeke ukondla ulwelo kwi-evaporator.Ukutshatyalaliswa kombane kuneenzuzo zeendleko eziphantsi kunye nokulawula okulula, kodwa iindleko zokusebenza ziphezulu.Ngokuqhelekileyo isetyenziselwa ukutshitshiswa kwezixhobo zokugcina ezibandayo, kungekhona ukutshitshiswa kwezixhobo zefriji.Kumaqondo obushushu ahlukeneyo, iimfuno zezakhono zokugquma kufuneka zahluke, kwaye umthamo ofunekayo wokupholisa kufuneka wohluke.Ukusekwa kokugcinwa okubandayo kufuneka kwenziwe ngokwezifiso ngokuhambelana nendawo yesicelo sangempela somthengi kunye nesicelo, ngaphandle kokuba akukho mfuneko ekhethekileyo yokuthatha indlela yokulinganisa.
3. I-gas defrosting eshushu kukusetyenziswa kwe-steam ye-refrigerant ene-superheated ekhutshwe yi-compressor ukukhulula ubushushu kwi-evaporator kwaye inyibilike i-frost layer kumphezulu we-evaporator.Inkqubo yokucima igesi eshushu inzima kwaye ixabiso liphezulu.Kodwa umphumo wokunciphisa ungcono.Xa isetyenziswe kwinkqubo ye-ammonia, ioli eqokelelwe kwi-evaporator ingaphinda ikhutshwe kwi-drain okanye kwi-reservoir ye-low pressure circulation reservoir.Kwinkqubo yokutshatyalaliswa kwegesi eshushu, uxinzelelo lulawulwa ngokubanzi kwi-0.6MPa.Zama ukusebenzisa irhasi yoxinzelelo oluphezulu ekhutshiweyo kwicompressor yenqanaba elinye lokuyinyibilikisa.Ubusika bunokufaneleka ukunciphisa amanzi okupholisa okanye ukunciphisa inani le-condensers, ukwandisa ubushushu bokukhupha, ukunciphisa ixesha lokunciphisa.Kwiinkqubo ze-ammonia, i-ammonia eshushu yokutshatyalaliswa kufuneka idibaniswe nombhobho wokukhupha we-oil separator.
4. Ukutshatyalaliswa kwamanzi kukutshiza amanzi kumphezulu we-evaporator ngesixhobo sokutshiza ukunyibilikisa iqabaka.Inkqubo yokutshatyalaliswa kwamanzi inesakhiwo esiyinkimbinkimbi kunye neendleko eziphezulu, kodwa umphumo omuhle kunye neendleko eziphantsi.Ukuchithwa kwamanzi kunokususa kuphela umaleko weqabaka kumphezulu ongaphandle we-evaporator, kwaye ayikwazi ukusombulula isiphumo esibi sokuqokelelwa kweoli kwi-evaporator ekugqithiseni ubushushu.Into ebaluleke kakhulu yibhodi yokugcina ebandayo, edla ngokuveliswa kwangaphambili ngumenzi webhodi yokugcina ebandayo kwaye inobude obusisigxina, ububanzi kunye nobukhulu.100mm ibhodi yokugcina ebandayo engqindilili idla ngokusetyenziselwa ukugcina ubushushu obuphezulu naphakathi, ibhodi yokugcina ebandayo eyi-120mm okanye i-150mm idla ngokusetyenziselwa ukugcinwa kobushushu obuphantsi kunye nokugcinwa komkhenkce.
5. Ukutshatyalaliswa kwamanzi omoya oshushu ziindlela ezimbini zokutshatyalaliswa okushushu kunye nokuchithwa kwamanzi asetyenziswa ngexesha elifanayo, ezigxininise iinzuzo zombini, kwaye zinokususa ngokukhawuleza kunye ngokufanelekileyo iqabaka ebusweni be-evaporator kunye nokuphelisa ukuqokelelwa kweoli. ngaphakathi kwe-evaporator.Xa i-defrosting, irhasi eshushu ithunyelwa kuqala kwi-evaporator ukwahlula umaleko weqabaka ukusuka kumphezulu we-evaporator, emva koko amanzi atshizwe ukuze ahlambe ngokukhawuleza umaleko weqabaka.Emva kokuba unikezelo lwamanzi lunqunyulwe, umphezulu we-evaporator "yomiswa" ngomoya oshushu ukukhusela ifilimu yamanzi angaphezulu kwiqhwa kunye nokuchaphazela ukuhanjiswa kobushushu.Ngaphambili, abavelisi bebhodi yokugcina ebandayo basebenzisa i-polyethylene kunye ne-polystyrene njengezinto eziphathekayo.Ngoku kukho ukusebenza okungcono kwebhodi yesandwich ye-polyurethane.Uxinaniso lwezixhobo zokugquma amagwebu ePolystyrene luphantsi, alunakugqunywa.Ngokuqhelekileyo zisetyenziselwa izixhobo ezikhethekileyo.I-Polyethylene yinto efanelekileyo ekrwada.Ngokusebenzisa umlinganiselo othile, unogwebu ngaphandle koxinaniso olufanelekileyo, umphumo wokugquma ulungile, amandla okuthwala owomeleleyo wemathiriyeli yokugquma.Ipleyiti yePolyurethane ingcono, inomsebenzi ongcono wokugquma kwaye ayifunxa ukufuma, kodwa eli xabiso lokugcinwa libandayo liphezulu kancinci.
