Isici se-defrost heater singenye yezingxenye ezibalulekile eziqandisini naseziqandisini. Umsebenzi waso oyinhloko ukuvimbela ukwakheka kweqhwa ngokuncibilikisa ungqimba lweqhwa oluqongelelwe kuma-evaporator coils. Ukwakheka kweshubhu ye-defrost heater kubalulekile ekugcineni ukusebenza okuvamile kwemishini. Ngokukhethekile, lapho umoya ngaphakathi kwesiqandisini noma esiqandisini udlula ku-evaporator ukuze uphole, umswakama emoyeni ungancipha futhi kancane kancane uqine ebusweni be-evaporator. Uma lezi zingqimba zeqhwa zingasuswa ngesikhathi, zizoqina kancane kancane futhi zivimbele ukujikeleza komoya obandayo okusebenzayo, ngaleyo ndlela kuthinte ukufana nokuzinza kokushisa kwangaphakathi kwemishini.
Ukuqinisekisa ukuthi amafriji noma amafriji angahlinzeka njalo ngendawo yokushisa ephansi, abakhiqizi bavame ukufaka uhlelo lokuncibilikisa oluzenzakalelayo emishinini. Ingxenye eyinhloko yalolu hlelo iyinto yokushisa encibilikisa iqhwa, eqala ngezikhathi ezithile ezinqunyiwe bese idlulisela inani elifanele lokushisa kuma-coil e-evaporator ukuze kuncibilikiswe iqhwa eliqongelelwe. Lo msebenzi wokuncibilikisa iqhwa ngezikhathi ezithile awusizi nje kuphela ukugcina ukujikeleza komoya okubushelelezi ngaphakathi kwemishini kodwa futhi uthuthukisa kakhulu ukusebenza kahle kwefriji futhi unciphise ukusetshenziswa kwamandla.
Umgomo wokuncibilikisa amafriji - Iyini ifriji epholiswe umoya
Inzuzo enkulu yesiqandisi esipholiswa umoya ukuthi asinaqhwa. Ngokungafani neziqandisi ezinezinhlelo zokuqandisa, isiqandisi esipholiswa umoya asinangaphakathi elimanzi njalo, futhi ukudla akunamatheli ndawonye. Ngaphezu kwalokho, isiqandisi esipholiswa umoya sinokujikeleza okuqhubekayo komoya obandayo, ohlungwa uhlelo lokususa iphunga, futhi iphunga langaphakathi lizogcinwa lisha isikhathi eside, ngaphandle “kwephunga lesiqandisi” elingathandeki. Isiqandisi esipholiswe umoya asiyona iqhwa; kunalokho, iqhwa liyaqina ku-evaporator. Njengoba lingaphakathi esiqandisini, asikwazi ukulibona ngqo ngomnyango wesiqandisi uvulekile, ngakho-ke libizwa ngokomfanekiso ngokuthi alinaqhwa. Ngaphezu kwalokho, ngoba isiqandisi esipholiswe umoya singancibilika ngokuzenzakalelayo.
Umgomo wokuncibilikisa isiqandisi esipholile ngomoya - Umgomo wokusebenza wokuncibilikisa isiqandisi esipholile ngomoya
Ngemva kokuba inqubo yokuncibilikisa isiqediwe emjikelezweni odlule, isibali sikhathi sokuncibilikisa sithinta umugqa ompunga bese umugqa ophuzi uxhumekile, bese kuthi isibali sikhathi, i-compressor, kanye nefeni konke kuqale ukusebenza ngasikhathi sinye. Isibali sikhathi sokuncibilikisa sixhunywe ngokulandelana nesibali sikhathi sokuncibilikisa, kodwa ngenxa yokumelana okukhulu kwangaphakathi kwesibali sikhathi sokuncibilikisa kanye nokumelana okuncane kwangaphakathi kwesibali sikhathi sokuncibilikisa, iningi lamandla kagesi lifakwa kusibali sikhathi sokuncibilikisa, bese isibali sikhathi sokuncibilikisa sikhiqiza ukushisa okuncane kakhulu. Lapho isibali sikhathi sokuncibilikisa kanye ne-compressor zisebenza ngasikhathi sinye isikhathi esingamahora ayisishiyagalombili, oxhumana nabo bomugqa ompunga wesibali sikhathi sokuncibilikisa kanye nomugqa ophuzi kuyaxhunywa. Isibali sikhathi sokuncibilikisa sinikwa amandla ngqo yi-fuse kanye ne-defrost switch, bese kuthi imoto yokuncibilikisa ifinyezwe yi-defrost control switch. Isibali sikhathi sokuncibilikisa siyayeka ukusebenza.
Uma iqhwa selincibilike ngokuphelele, lapho izinga lokushisa lobuso be-evaporator lenyuka laya ku-10-16°C, oxhumana nabo beswishi yokulawula izinga lokushisa elincibilikayo bayanqanyulwa kwisekethe yokuncibilikisa, futhi ngasikhathi sinye, i-timer yokuncibilikisa iqala ukusebenza. Ngemva kwemizuzu engaba mi-5, oxhumana nabo bomugqa ompunga kanye nomugqa ophuzi baphinde baxhunywe, kuqedwa inqubo eyodwa yokuncibilikisa okuzenzakalelayo. I-compressor kanye nefeni ziqala ukusebenza futhi ukuze ziqandiswe. Ngemuva kwalokho, lapho izinga lokushisa le-evaporator lehla liye ekushiseni kabusha kweswishi yokulawula izinga lokushisa elincibilikayo, iswishi yokulawula izinga lokushisa ivaliwe ukuze kuxhunywe i-heater yokuncibilikisa, kulungiselelwe ukuncibilikisa okulandelayo.
Kodwa-ke, uma i-defrost heating element ingasebenzi kahle, njengokuguga, ukusha, noma ukuxhumana okubi kwesekethe, kungavimbela umjikelezo wokuncibilika ekusebenzeni kahle. Ngenxa yalokho, i-frost ku-evaporator inganqwabelana ngokushesha, ivimbe indlela yokugeleza komoya futhi yenze kube nzima ngemishini ukugcina izinga lokushisa elibekiwe. Lesi simo asigcini nje ngokuphazamisa ukugcinwa kokudla kodwa futhi sibeka ukucindezeleka okwengeziwe ezingxenyeni ezibalulekile njenge-compressor, futhi singase siholele ekulimaleni kwemishini. Ngakho-ke, uma ubona ukwehla kokusebenza kokupholisa kwesiqandisi sakho noma i-freezer, ukunqwabelana kwe-frost okungavamile ngaphakathi, noma ukwanda okukhulu kokusetshenziswa kwamandla, kufanele uhlole ngokushesha isimo sesistimu yokuncibilika.
Uma usola ukuthi into yokushisa encibilikisayo inephutha, kunconywa ukuthi uthathe izinyathelo ezilandelayo ngokushesha okukhulu: Okokuqala, nqamula ukunikezwa kwamandla kwemishini ukuqinisekisa ukuphepha; okwesibili, sebenzisa i-multimeter ukuhlola inani lokumelana nento yokushisa ukuze unqume ukuthi ingaphakathi kwebanga elijwayelekile lokusebenza; ekugcineni, uma kuqinisekiswa ukuthi into yonakele, udinga ukuthenga ingxenye entsha efanelana nomodeli wokuqala ukuze uyishintshe. Ngokulondoloza nokufaka esikhundleni izingxenye ezinephutha ngesikhathi esifanele, ungandisa ngempumelelo impilo yesevisi yesiqandisi noma isiqandisi futhi uqinisekise ukuthi sihlala sisesimweni esihle kakhulu sokusebenza.
