Iinkqubo ezininzi zomoya opholileyo kunye nezibandayo zibeka iiyunithi zazo zokufudumeza ngaphandle ngezizathu ezibini eziphambili. Okokuqala, oku kusebenzisa ubushushu obupholileyo obungaphandle ukuze kususwe ubushushu obufunxwa yi-evaporator, kwaye okwesibini, ukunciphisa ungcoliseko lwengxolo.
Iiyunithi zokufunxa zihlala ziquka iicompressor, ii-condenser coils, ii-condenser fans zangaphandle, iicontactors, ii-starting relay, ii-capacitors, kunye nee-solid state plates ezineesekethe. I-receiver idla ngokudityaniswa kwiyunithi yokufunxa yenkqubo yokufriji. Ngaphakathi kwiyunithi yokufunxa, i-compressor idla ngokuba ne-heater eqhagamshelwe ezantsi okanye kwi-crankcase. Olu hlobo lwe-heater ludla ngokubizwa ngokuba yi-isifudumezi se-crankcase.
Iisifudumezi se-crankcase yecompressorsisifudumezi sokumelana esidla ngokubotshelelwa ezantsi kwe-crankcase okanye sifakwe emngxunyeni ongaphakathi kwe-crankcase ye-compressor.Izifudumezi zeCrankcaseZifumaneka rhoqo kwi-compressors apho ubushushu obuphakathi buphantsi kunobushushu bokufudumeza okusebenzayo kwenkqubo.
Ioyile ye-crankcase okanye ioyile ye-compressor inemisebenzi emininzi ebalulekileyo. Nangona i-refrigerant ilulwelo olusebenzayo olufunekayo ekupholiseni, ioyile iyadingeka ukuthambisa iindawo zoomatshini ezihambayo ze-compressor. Kwiimeko eziqhelekileyo, kusoloko kukho inani elincinci leoyile eliphuma kwi-crankcase ye-compressor kwaye lijikeleza ne-refrigerant kuyo yonke inkqubo. Ekuhambeni kwexesha, isantya esifanelekileyo se-refrigerant kwi-system tube siya kuvumela la ma-oyile aphumileyo ukuba abuyele kwi-crankcase, kwaye kungenxa yesi sizathu sokuba ioyile kunye ne-refrigerant kufuneka zinyibilike. Kwangaxeshanye, nangona kunjalo, ukunyibilika kweoyile kunye ne-refrigerant kunokubangela enye ingxaki yenkqubo. Ingxaki kukufuduka kwe-refrigerant.
Ukufuduka yinto eyenzeka rhoqo. Le yinkqubo apho iifriji ezingamanzi kunye/okanye zomphunga zifuduka okanye zibuyela kwi-crankcase kunye nemicu yokufunxa ye-compressor ngexesha lomjikelo wokuvala kwe-compressor. Ngexesha lokucinywa kwe-compressor, ingakumbi ngexesha lokucinywa kwexesha elide, i-refrigerant kuya kufuneka ifuduselwe okanye ifuduselwe apho uxinzelelo luphantsi khona. Ngokwendalo, ulwelo luhamba ukusuka kwiindawo ezinoxinzelelo oluphezulu ukuya kwiindawo ezinoxinzelelo oluphantsi. I-crankcase idla ngokuba noxinzelelo oluphantsi kune-evaporator kuba ineoyile. Ubushushu obupholileyo obujikeleze umoya buyandisa uxinzelelo oluphantsi lomphunga kwaye bunceda ukufunxa umphunga we-refrigerant kulwelo olukwi-crankcase.
Ioyile efrijiweyo ngokwayo inoxinzelelo oluphantsi lomphunga, kwaye nokuba ifriji ikwimeko yomphunga okanye ikwimeko yolwelo, iya kugeleza iye kwioyile efrijiweyo. Enyanisweni, uxinzelelo lomphunga lweoyile efrijiweyo luphantsi kakhulu kangangokuba nokuba i-vacuum ye-100 microns itsalwa kwinkqubo yokufriji, ayizukutsha. Umphunga wezinye iioyile ezifriziweyo uncitshiswa uye kwi-5-10 microns. Ukuba ioyile ayinaxinzelelo lomphunga oluphantsi kangako, iya kutsha nanini na xa kukho uxinzelelo oluphantsi okanye i-vacuum kwi-crankcase.
Ekubeni ukufuduka kwe-refrigerant kunokwenzeka ngomphunga we-refrigerant, ukufuduka kungenzeka ukunyuka okanye ukwehla. Xa umphunga we-refrigerant ufika kwi-crankcase, uya kufunxwa kwaye unciphe kwi-oyile ngenxa yokungavisisani kwe-refrigerant/oyile.
Ngexesha lomjikelo ovaliweyo omde, i-liquid refrigerant iya kwenza umaleko odibeneyo ezantsi kweoyile kwi-crankcase. Oku kungenxa yokuba ii-liquid refrigerants zinzima kuneoyile. Ngexesha lomjikelo omfutshane wokuvala i-compressor, i-refrigerant efudukileyo ayinalo ithuba lokuhlala phantsi kweoyile, kodwa iya kuqhubeka ixubana neoyile kwi-crankcase. Ngexesha lokufudumala kunye/okanye iinyanga ezibandayo xa i-air conditioner ingadingeki, abanini bezindlu badla ngokucima umbane kwiyunithi ye-air-conditioner yangaphandle. Oku kuya kubangela ukuba i-compressor ingabi nabushushu be-crankcase kuba i-crankcase heater iphelelwe ngamandla. Ukufuduka kwe-refrigerant kwi-crankcase ngokuqinisekileyo kuya kwenzeka ngeli xesha lide.
Xa ixesha lokupholisa liqalile, ukuba umninimzi akayivuli i-circuit breaker ubuncinci iiyure ezingama-24-48 ngaphambi kokuba aqalise iyunithi yomoya opholileyo, kuya kubakho ukugqwala okukhulu kwe-crankcase kunye noxinzelelo ngenxa yokufuduka kwexesha elide kwe-refrigerant engajikeleziyo.
Oku kunokubangela ukuba i-crankcase ilahlekelwe linqanaba elifanelekileyo leoyile, konakalise neebheringi kwaye kubangele nezinye iingxaki zoomatshini kwi-compressor.
Izifudumezi zeCrankcase zenzelwe ukunceda ukulwa nokufuduka kwe-refrigerant. Indima yesifudumezi se-crankcase kukugcina ioyile kwi-compressor crankcase kubushushu obuphezulu kuneyona ndawo ibandayo yenkqubo. Oku kuya kubangela ukuba i-crankcase ibe noxinzelelo oluphezulu kancinci kunezinye iinkqubo. Isifudumezi esingena kwi-crankcase siya kuthi emva koko sivuthwe size sibuyiselwe kumgca wokufunxa.
Ngexesha elingengomjikelo, ukufuduka kwe-refrigerant ukuya kwi-crankcase ye-compressor yingxaki enkulu. Oku kunokubangela umonakalo omkhulu kwi-compressor
