Lapho imishini eqandisi isebenza, ingaphezulu lekhoyili yokuhwamuka kwama-frow ithambekele kwiqhwa. Uma isithwathwa simikhulu kakhulu, kuzothinta umphumela wokupholisa, ngakho-ke kudinga ukungcoliswa ngesikhathi. Ngokusebenza kwe-Defrosting of imishini yokushisa ephansi yokushisa kanye nemishini yokushisa yokushisa okuphakathi, ngenxa yamabanga okushisa ahlukene, izakhi zokulawula ezihambisanayo nazo zihlukile. Izindlela zokuvikela ngokuvamile zifaka phakathi ukuvala i-Defrosting, defrosting ngokushisa okuzenzele, futhi i-defrosting ngokungeza amadivayisi angaphandle.
Kwemishini yokushisa yokushisa ephakathi, izinga lokushisa elisebenzayo lekhoyili eliguqukayo liphansi kunokushisa kwamaphoyinti, futhi liphakeme kunokushisa kwamaphoyinti okushibilika ngesikhathi sokuvalwa, ngakho-ke indlela yokuvala i-defrosting ivame ukusetshenziselwa amakhabethe okushisa aphansi. Ngesikhathi sokusebenza, izinga lokushisa kwikhabethe licishe libe ngu-1 ° C, futhi izinga lokushisa lekhoyili livame cishe yi-10 ° C ephansi kunalokho kwiKhabhinethi. Lapho umshini uvaliwe, izinga lokushisa lomoya kwikhabethe liphakeme kunokushisa kwamaphoyinti, i-fan ku-evaporator iyaqhubeka nokugijima, futhi ukufutheka okuqondile kutholakala umoya kwikhabethe elisezingeni eliphakeme. I-Defrost ingenziwa nangesikhathi noma okungahleliwe. I-defrosting yesikhathi yokuphoqa i-compressor ukuthi iyeke ukugijima isikhathi esithile. Ngalesi sikhathi, umoya kwikhabethe uzokhipha ikhoyili. Isikhathi sokuqapha kanye nobude besikhathi se-defrosting bulawulwa yisilinganiso sesikhathi ngokuya nge-set oda. Ngokuvamile isethwe ukuvala i-compressor lapho i-freezer isendaweni ephansi kakhulu yokushisa. Isikhathi se-defrost singasetha izikhathi eziningi zokuzivikela kungakapheli amahora angama-24.
Ngemishini yokushisa ephansi yokushisa, izinga lokushisa elisebenzayo le-evaporator liphansi kunokushisa kwamaphoyinti, futhi indlela ebekelwe isikhathi esinqunyelwe isikhathi okufanele isetshenziswe. Lapho izinga lokushisa lomoya ku-freezer lisezingeni eliphansi kakhulu, ukushisa kudinga ukuhlinzekwa kumhwamuko we-evaporator ukuze u-defrosting. Ukushisa okudingekayo kwe-defrosting ngokuvamile kuvela ekushiseni kwangaphakathi ohlelweni nokushisa kwangaphandle ngaphandle kohlelo.
Indlela ye-defrosting nokushisa kwangaphakathi ivame ukubizwa ngokuthi i-hot air defrosting. Isebenzisa umusi oshisayo ovela ku-compressor ukuxhuma ipayipi eliphumayo le-compressor kuya kokungeniswa kwe-evaporator, futhi kwenza ukuthi umusi oshisayo uhambe ngokugcwele kuze kube yilapho ungqimba lwesithwathwa kuncibilike ngokuphelele. Le ndlela iyindlela yokonga ngokwezomnotho neyendla ngoba amandla asetshenziselwa i-defrosting avela ohlelweni uqobo.
Uma i-Evaporator ingumugqa owodwa futhi i-valve yokwanda iyi-T-hlobo umugqa, igesi eshisayo ingangeniswa ngqo kumhwamuko we-efrorator ukuze u-defrosting. Uma kunamapayipi amangaki, i-Hot Steam kumele ifakwe phakathi kwe-valve yokwanda kanye nesiqandisi sokugeleza kwesiqandisi, ukuze umusi oshisayo ugeleze ungene kupayipi ngalinye lomfaki ngokulinganayo, ukuze uzuze inhloso yokukhohlisa ngokulinganayo.
Ukusebenza kwe-Defrosting ngokuvamile kuqalwa ngu-timer. Ngemishini ehlukene noma ithi, isibali sesikhathi sisethwe ngesikhathi esihlukile ukuvikela ukwanda kokusetshenziswa kwamandla noma izinga lokushisa elingafanele lokudla ngenxa yesikhathi eseqile.
Ukuqedwa kwe-defrost kunganqunywa ngesikhathi noma lokushisa. Uma izinga lokushisa linqanyulwa, idivaysi yokuzwakala lokushisa idinga ukusethwa ukuze ibone ukuthi izinga lokushisa le-evaporator liphakeme kunokushisa kwamaphoyinti okuqaqa. Uma idivaysi yokuzwakala yokushisa ibona ukuthi izinga lokushisa liphakeme kunokushisa kwamaphoyinti, umusi oshisayo ongena ku-evaporator kufanele unqunywe ngokushesha ukuze ubuyisele uhlelo ekusebenzeni okujwayelekile. . Kulokhu, isikhathi sesikhathi semishini sivame ukufakwa ngasikhathi sinye, futhi ukusebenza kwe-defrosting kunqanyulwa ngokuya ngesiginali kagesi ye-Lishisa Stering element. Inqubo eyisisekelo yesenzo sengxenye ngayinye yilena: Lapho kusethi lokushisa le-defrosting lifinyelelwa, oxhumana naye we-timer uvaliwe, i-solenoid valve ivuliwe, i-fan plavve iyaqhubeka nokugijima, futhi umusi oshisayo uthunyelwa ku-evaporator. Lapho izinga lokushisa lekhoyili likhuphuka libe yinani elithile, oxhumana nabo be-thermostat bavuthiwe, i-X terminal kwi-timer inqanyuliwe, futhi i-defrosting inqanyulwa. Lapho izinga lokushisa lekhoyili liwela ngenani elithile, ukushintshwa koxhumana nabo be-thermostat kanye nokuqalisa kabusha kwabalandeli.
Ngesikhathi sokusebenza okushisayo kweSteam Defrosting, isibali sikhathi sidinga ukuxhumanisa ukusebenza kwalezi zinto ezilandelayo ngasikhathi sinye:
1) I-Steam Steam Solenoid Valve kumele ivulwe;
2) Abathandi be-evaporator bayeka ukugijima, ngaphandle kwalokho umoya obandayo awunakuvikeleka ngempumelelo;
3) I-compressor kumele iqhubeke ngokuqhubekayo;
4) Lapho ukushintshwa kokuqedwa kwe-defrosting kungakwazi ukunqamula i-defrosting, isikhathi kufanele sibekwe nesikhathi esiphezulu se-defrosting esivunyelwe;
5) Drain heater unamandla.
Eminye imishini yefriji isebenzisa umthombo wokushisa wangaphandle wokuqamba, ngokwesibonelo, ukufaka idivaysi yokufudumeza kagesi eduze kwekhoyili. Le ndlela ye-defrosting nayo ilawulwa yisikhathi. Amandla we-defrost asuselwa kudivayisi yangaphandle, ngakho-ke akunjalo njengokomnotho njengomoya oshisayo we-defrosting. Kodwa-ke, uma ibanga lepayipi lide, ukusebenza kahle kwe-Electric Heating Defrosting kuphakeme kakhulu. Lapho ipapor eshisayo ye-vapor inde, ukuqanda eqamba kuthambekele ekuvuselelekeni, okuholele ekutheni isiqalo esinciphile kakhulu, futhi ngisho nesiqandisi esingutshani esingena ku-compressor, sibangele ukulimala kwe-compressor. Isikhathi se-Thermal Defrost sidinga ukulawula ukusebenza kwalezi zinto ezilandelayo:
1) Ezimweni eziningi, abalandeli be-evaporator bayayeka ukugijima;
2) I-compressor iyayeka ukugijima;
3) I-heater kagesi inamandla;
4) Drain heater unamandla.
Inzwa yokushisa esetshenziswe ngokubambisana ne-timer ngokuvamile idivaysi eyodwa-pole-pilo double enezintambo ezi-3 zokuhola, othintana naye oshisayo kanye nokuxhumana okubandayo. Lapho izinga lokushisa lekhoyili likhuphuka, i-terminal yokuxhumana eshisayo iyanamandla, kwathi lapho izinga lokushisa lekhoyili liwela, i-terminal yokuxhumana yamakhaza iyamandla.
Ukuze ugweme isikhathi se-defrost isikhathi eside kakhulu noma ukulayisha ngokweqile kwe-compressor ngemuva kokuqamba, ukushintshwa kwe-defrost ukushintshwa, okubizwa nangokuthi switch okulethiwe kwabalandeli, kungafakwa ohlelweni. Isivungu sokushisa se-defrost inkathi yokushintsha ngokuvamile sisethwe ekugcineni kwe-evaporator. Lapho ungqimba lweqhwa ku-coil ancibilike ngokuphelele, inzwa yokushisa ye-defrost surverer couning coutions ingabona ukushisa kwe-defrost, vala oxhumana nabo kwi-adverler, bese unika amandla i-defrost ukunqamula i-solenoid valve. Buyisela uhlelo ukuze upholile. Ngalesi sikhathi, i-evaporator kanye nomlandeli abaqali ngokushesha, kepha bazoqala ukugijima ngemuva kokubambezeleka kokuqeda ukushisa futhi bagweme ukulayisha ngokweqile i-compressional ngenxa yengcindezi yokuthola amandla ngokweqile ngemuva kokucindezela. Ngasikhathi sinye, gwema i-fan ukushaya umoya omanzi ekudleni kwikhabhinethi.
