Uninzi lweenkqubo zokupholisa umoya kunye nezikhenkcezisi zifumana iiyunithi zazo zokujiya ngaphandle ngenxa yezizathu ezibini eziphambili. Okokuqala, oku kuthatha ithuba lobushushu obupholileyo obungaphandle ukususa ubushushu obufunxwa ngumphunga, okwesibini, ukunciphisa ungcoliseko lwengxolo.
Iiyunithi zokudibanisa zihlala ziquka iicompressor, iikhoyili zecondenser, iifeni zecondenser zangaphandle, abafowunelwa, ukuqalisa ukuhanjiswa, ii-capacitors, kunye neepleyiti zesimo eziqinileyo ezinesekethe. Ummkeli udla ngokudityaniswa kwiyunithi yokunciphisa inkqubo yefriji. Ngaphakathi kweyunithi yokujiya, icompressor idla ngokuba nesifudumezi ngandlel' ithile siqhagamshelwe ezantsi okanye kwikhrankcase. Olu hlobo lwesifudumezi ludla ngokubizwa ngokuba yi-aiheater crankcase.
Iicompressor crankcase heatersisifudumezi esixhathisayo esihlala sibotshelelwa emazantsi ekrankcase okanye sifakwe kwiqula elingaphakathi kwekhrankcase yecompressor.Izifudumezi zeCrankcasezifumaneka rhoqo kwiicompressors apho ubushushu be-ambient bungaphantsi kunobushushu benkqubo esebenza ngumphunga.
Ioli ye-crankcase okanye ioli ye-compressor inemisebenzi emininzi ebalulekileyo. Nangona isikhenkcezisi silulwelo olusebenzayo olufunekayo ukupholisa, i-oyile iyafuneka ukuthambisa iindawo ezihambayo zecompressor. Ngaphantsi kweemeko eziqhelekileyo, kukho rhoqo inani elincinci leoli eliphuma kwi-crankcase ye-compressor kunye nokujikeleza kunye nefriji kuyo yonke inkqubo. Ngokuhamba kwexesha, isantya esifanelekileyo sesikhenkcisi kwityhubhu yesixokelelwano siyakuvumela ezi oyile zibalekile ukuba zibuyele kwikrankcase, kwaye kungenxa yesi sizathu ukuba i-oyile kunye nesikhenkcisi kufuneka zinyibilike. Ngexesha elifanayo, nangona kunjalo, ukunyibilika kweoli kunye nefriji kunokubangela enye ingxaki yenkqubo. Ingxaki kukufuduka kwefriji.
Ukufuduka yinto ye-aperiodic. Le yinkqubo apho ulwelo kunye/okanye izikhenkcezisi zomphunga zifuduka okanye zibuyele kwikhrankcase yecompressor kunye nemigca yokufunxa ngexesha lomjikelo wokuvalwa kwecompressor. Ngexesha lokuphuma kwecompressor, ngakumbi ngexesha lokuphuma okwandisiweyo, ifriji iya kufuneka ihanjiswe okanye ifuduselwe apho uxinzelelo luphantsi. Ngokwendalo, ulwelo luphuma kwiindawo ezinoxinzelelo oluphezulu ukuya kwiindawo ezinoxinzelelo oluphantsi. I-crankcase idla ngokuba noxinzelelo oluphantsi kune-evaporator kuba iqulethe ioli. Iqondo lobushushu elipholileyo le-ambiente likhulisa isenzeko soxinzelelo lomphunga osezantsi kwaye inceda ukuthoba umphunga wefriji kulwelo olukwikhrankcase.
Ioli efrijini ngokwayo inoxinzelelo oluphantsi lomphunga, kwaye ingaba i-refrigerant ikwimeko ye-vapor okanye i-liquid state, iya kuhamba kwioli efrijini. Ngapha koko, uxinzelelo lomphunga weoyile engumkhenkce luphantsi kangangokuba nokuba kutsalwe isifunxa seemicrons eziyi-100 kwisikhenkcisi, asisayi kujika sibe ngumphunga. Umphunga wamanye amafutha omkhenkce uyancitshiswa ube yi-5-10 microns. Ukuba i-oyile ayinalo olo xinzelelo lomphunga oluphantsi ngolo hlobo, iya kuba ngumphunga nanini na xa kukho uxinzelelo oluphantsi okanye i-vacuum kwi-crankcase.
Ekubeni ukufuduka kwefriji kunokwenzeka ngomphunga opholileyo, ukufuduka kunokuthi kwenzeke ukunyuka okanye ukuhla. Xa i-steam yefriji ifikelela kwi-crankcase, iya kuxutywa kwaye ifakwe kwioli ngenxa yokungahambi kakuhle kwefriji / ioli.
Ngexesha lomjikelo omde ovaliweyo, isikhenkcezisi solwelo siya kwenza umaleko odibeneyo emazantsi e-oyile ekwikhrankcase. Oku kungenxa yokuba iifriji zolwelo zinzima kune-oyile. Ngexesha lemijikelo emifutshane yokuvala icompressor, ifriji efudukayo ayinalo ithuba lokuzinza phantsi kweoyile, kodwa iya kuhlala ixuba neoyile ekwikhrankcase. Ngexesha lokufudumeza kunye / okanye iinyanga ezibandayo xa umoya womoya ungafunekiyo, abanini bezindlu bahlala becima ukucima umbane kwiyunithi ye-condensing yangaphandle ye-air-conditioning. Oku kuya kubangela ukuba icompressor ingabinabushushu becrankcase kuba isifudumezi secrankcase siphelelwe ngamandla. Ukufuduka kwefriji ukuya kwi-crankcase ngokuqinisekileyo kuya kwenzeka kulo mjikelo omde.
Nje ukuba ixesha lokupholisa liqalise, ukuba umninimzi akawujiki umjikelo wesiphaluka umva ubuncinane kwiiyure ezingama-24-48 ngaphambi kokuba aqalise iyunithi yokupholisa umoya, i-crankcase enogwebu olunogwebu kunye noxinzelelo luya kwenzeka ngenxa yokufuduka kwexesha elide lefriji engajikeleziyo.
Oku kunokubangela ukuba i-crankcase ilahlekelwe yinqanaba le-oyile efanelekileyo, iphinde yonakalise iibheringi kwaye ibangele ukusilela komatshini ngaphakathi kwecompressor.
Izifudumezi zeCrankcase ziyilelwe ukunceda ukulwa nokufuduka kwefriji. Indima yesifudumezi secrankcase kukugcina ioyile kwicompressor crankcase kwiqondo lobushushu elingaphezulu kweyona ndawo ibandayo yenkqubo. Oku kuya kubangela ukuba i-crankcase ibe noxinzelelo oluphezulu kancinane kunenkqubo yonke. Isikhenkcisi esingena kwikhrankcase siya kuthi emva koko sibe ngumphunga kwaye siqhutyelwe emva kumgca wokufunxa.
Ngethuba lexesha elingeyiyo imijikelo, ukufuduka kwefriji kwi-compressor crankcase yingxaki enkulu. Oku kunokubangela umonakalo omkhulu wecompressor
