Ukukhenkceza kwizibuko lomoya elibuyayo lecompressor yokugcina ebandayo yinto eqhelekileyo kwinkqubo yesikhenkcisi.Ngokubanzi, ayiyi kudala ingxaki yenkqubo ngokukhawuleza, kwaye i-frosting encinci ayiqhelekanga ukujongana nayo.Ukuba i-frost phenomenon inzima kakhulu, ke imfuneko yokuqala yokucima imbangela yeqhwa
Okokuqala, i-compressor air return port iqabaka
Ukukhenkceza kwindawo yokungenisa umoya ebuyayo kubonisa ukuba ubushushu bomoya obubuyayo becompressor buphantsi kakhulu.Emva koko yintoni eya kubangela ukubuya kweqondo lokushisa lomoya wecompressor liphantsi kakhulu?
Ubunzima obufanayo befriji, ukuba umthamo kunye noxinzelelo lutshintsha, ukushisa kuya kuba nokusebenza okuhlukeneyo.Ukuba iqondo lokushisa lokubuyisela i-compressor liphantsi, liya kubonisa ngokubanzi uxinzelelo oluphantsi lwegesi lokubuya kunye nomthamo ophezulu wefriji yomthamo ofanayo ngexesha elifanayo.Ingcambu yale meko kukuba isikhenkcezisi esihamba nge-evaporator asikwazi ukufunxa ngokupheleleyo ubushushu obufunwa kukwandiswa kwaso kwixabiso lobushushu obumiselwe kwangaphambili.
Zimbini izizathu zale ngxaki:
- Unikezelo lwefriji ye-throttle liquid luqhelekileyo, kodwa i-evaporator ayikwazi ukufunxa ubushushu ngokuqhelekileyo;
- i-evaporator heat absorption isebenza ngokuqhelekileyo, kodwa ukunikezelwa kwefriji ye-throttle kuninzi kakhulu, oko kukuthi, ukuhamba kwefriji kuninzi kakhulu, ngokuqhelekileyo siyaqonda ukuba ifriji ininzi.
Isibini, ngenxa yefluorine encinci ebangelwa yi-compressor ebuyisela iqabaka yerhasi
1.kuba ukuhamba kwefriji kuncinci kakhulu
Ukwandiswa kwefriji okuncinci kakhulu akuzukusebenzisa yonke indawo yomphunga, kwaye kuya kwenza kuphela ubushushu obuphantsi kwi-evaporator.Kwezinye iindawo, ngenxa yexabiso elincinci lefriji kunye nokwandiswa ngokukhawuleza, ukushisa kwendawo kuphantsi kakhulu, kwaye i-evaporator frost phenomenon ibonakala.
Emva kweqabaka yendawo, ngenxa yokwenziwa komgangatho wokugquma ubushushu kumphezulu we-evaporator kunye nokuhanjiswa kobushushu obuphantsi kule ndawo, ukwandiswa kwesikhenkcezisi kudluliselwa kwezinye iindawo, kwaye ngokuthe ngcembe yonke i-evaporator iqabaka okanye i-icing phenomenon, yonke i-evaporator. kwakheka umaleko wokugquma ubushushu, ngoko ke ukwandiswa kuya kunwenwa kumbhobho wokubuyisela isicinezeli okhokelela ekukhenkcezeni kwerhasi yokubuyisela icompressor.
2.ngenxa yexabiso elincinci lefriji
Uxinzelelo lobushushu obusezantsi kwi-evaporator lukhokelela kubushushu obuphantsi bomphunga, obuya kuthi ngokuthe ngcembe bukhokhelele ekujikeni kwi-evaporator ukwenza umaleko wokugquma ubushushu, kwaye udlulisele indawo yokwandisa kwigesi yokubuyisela icompressor, okukhokelela ekukhenkceni kwerhasi yecompressor.
Uxinzelelo lobushushu obusezantsi kwi-evaporator lukhokelela kubushushu obuphantsi bomphunga, obuya kuthi ngokuthe ngcembe bukhokhelele ekujikeni kwi-evaporator ukwenza umaleko wokugquma ubushushu, kwaye udlulisele indawo yokwandisa kwigesi yokubuyisela icompressor, okukhokelela ekukhenkceni kwerhasi yecompressor.
La manqaku mabini angasentla aya kubonisa i-evaporator frosting phambi kokuba icompressor ibuyisele iqabaka.
Enyanisweni, kwiimeko ezininzi kwi-frost phenomenon, okoko nje ukulungiswa kwevalve yegesi eshushu.Indlela ethile kukuvula isiciko esingasemva sevalve yegesi eshushu yokudlula, kwaye emva koko usebenzise i-No.8 hex wrench ukuguqula i-nut yokulungelelanisa ngaphakathi kwewotshi.Inkqubo yohlengahlengiso ayikhawulezi kakhulu.Ngokuqhelekileyo, iya kunqunyanyiswa emva kwesiqingatha sokujika, kwaye inkqubo iya kuqhuba ixesha elithile ukuze ibone imeko yeqabaka ngaphambi kokuba ithathe isigqibo sokuba iqhubeke nokulungelelanisa.Xa umsebenzi uzinzile kwaye i-frosting phenomenon ye-compressor iyanyamalala, qinisa i-cover cover.
Isithathu i-cylinder head frosting (ukukhenkceza okunzulu kwe-crankcase)
Ukukhenkceka kwentloko yesilinda kubangelwa sisixa esikhulu somphunga omanzi okanye icompressor yokufunxa ifriji.Ezona zizathu zoku:
- Ukuvulwa kwevalve yokwandisa i-thermal kukhulu kakhulu, kwaye ukufakwa kwepakethi yokuva iqondo lokushisa akulungile okanye kulungiswe ngokukhululekileyo, ukwenzela ukuba ukushisa okuvakalelwa kuphezulu kakhulu kwaye i-spool ivuleke ngokungaqhelekanga.
Ivalve yokwandisa i-thermal isebenzisa i-superheat kwindawo yokukhupha i-evaporator njengomqondiso wempendulo ukuvelisa isignali yokutenxa emva kokuyithelekisa nexabiso elinikiweyo lobushushu obuphezulu ukulungelelanisa ukuhamba kwefriji kwi-evaporator.Ngumlawuli othe ngqo osebenza ngokulinganayo, odibanisa umthumeli, umlawuli kunye ne-activator.
Ngokweendlela ezahlukeneyo zokulinganisa, iivalve zokwandiswa kwe-thermal zinokwahlulwa zibe:
Ivalve yokwandisa i-thermal elinganayo yangaphakathi;
Ivalve yokwandisa i-thermal elinganayo yangaphandle.
Ivalve yokwandisa i-thermal ivulwe kakhulu, iphakheji yokuva iqondo lokushisa ifakwe ngokungalunganga okanye ilungiswe ngokukhululekileyo, ukwenzela ukuba iqondo lokushisa liphezulu kakhulu kwaye i-spool ivuleke ngokungaqhelekanga, ibangela ukuba umthamo omkhulu womphunga omanzi ufunxe kwi-compressor, kubangele iqabaka kwintloko yesilinda.
Ivalve yokwandisa i-thermal ivulwe banzi kakhulu, iphakheji yokuva iqondo lokushisa ifakwe ngokungalunganga okanye ilungiswe ngokukhululekileyo, ukwenzela ukuba iqondo lokushisa liphezulu kakhulu, i-spool ivuliwe ngokungaqhelekanga, okukhokelela ekubeni umphunga omninzi omanzi ufunxe kwi-compressor, kwaye intloko yesilinda ineqabaka.
- Xa ivalve yonikezelo lwe-solenoid elulwelo ivuza okanye iyeka, ivalve yokwandisa ayivalwanga nkqi
Isixa esikhulu solwelo lwesikhenkcisi siye saqokelelana kwi-evaporator phambi kokuba siqalise.Le meko ikwalula ukubangela ulwelo lwecompressor hit!
- Ifriji eninzi kakhulu kwisistim
Inqanaba le-liquid kwi-condenser liphezulu, indawo yokudlulisa ubushushu obuncitshisiweyo iyancitshiswa, ukwenzela ukuba uxinzelelo lwe-condensing lunyuke, oko kukuthi, uxinzelelo ngaphambi kokuba i-valve yokwandisa, i-dose yefriji kwi-evaporator iyanda, i-refrigerant yolwelo ayinakunyuka ngokupheleleyo. kwi-evaporator, ngoko ke icompressor iphefumla umphunga omanzi, inwele ye-cylinder iyabanda okanye ikhenkceke, kwaye inokubangela "ukuvuthela kolwelo", kwaye uxinzelelo lwe-evaporation luya kuba phezulu.
