Ukushisa ama-heatersziyizingxenye ezibalulekile ezinhlelweni zesiqandisi, ikakhulukazi eziqandisini naseziqandisini, lapho indima yazo iwukuvimbela isithwathwa kumakhoyili e-evaporator. Ukwakheka kwezingqimba zesithwathwa kunganciphisa kakhulu ukusebenza kahle kwalezi zinhlelo, ekugcineni kuthinte umthamo wazo wokupholisa.
Iisiqandisi defrosting bafudumale tubeiyingxenye ebalulekile yesistimu yesiqandisi, esetshenziselwa ikakhulukazi ukuncibilikisa ungqimba lwesithwathwa oluqoqwe ku-evaporator emjikelezweni wesithwathwa ozenzakalelayo ukuze kuqinisekiswe ukusebenza kahle kwesiqandisi sesiqandisi.
Umsebenzi we-Defrost heater:
Ukunciphisa: Ngesikhathi sokusebenza kwesiqandisi, ingaphezulu le-evaporator lizoba nesithwathwa, futhi ungqimba oluqinile lwesithwathwa luzothinta umphumela wesiqandisi. Idefrost heater tubeincibilikisa ungqimba lwesithwathwa ngokufudumeza, ukuze i-evaporator ibuyele esimweni sokusebenza esivamile.
Isithwathwa esizihambelayo: Iziqandisi zesimanje zivame ukuhlonyiswa ngezinhlelo zesithwathwa ezizenzakalelayo laphodefrost bafudumale tubeizoqala ngesikhathi esimisiwe noma ngaphansi kwesimo esimisiwe futhi icishe ngokuzenzakalelayo ngemva kokuncibilika.
Umgomo wokusebenza we-heater ye-defrost ukushisa ikhoyili ye-evaporator ngezikhathi ezithile ukuze kuncibilike noma yisiphi isithwathwa esinqwabelene. Izifudumezi ze-defrost ezivame ukusetshenziswa kakhulu ziwela ezinhlotsheni ezimbili: uhlobo lokushisisa ngogesi kanye nohlobo lokushisa kwegesi eshisayo.
Ama-heaters kagesingokuvamile zifakwa eziqandisini zasendlini kanye namafriji. Lezi zifudumezi zenziwe ngezinto eziphikisanayo ezifana ne-nickel-chromium alloys, ezinokumelana okuphezulu futhi ezingakwazi ukukhiqiza ukushisa lapho okwamanje kudlula kuzo. Zibekwe ngobuhlakani eduze kwamakhoyili e-evaporator noma zifakwe ngqo kumakhoyili.
Lapho isiqandisi sisebenza emjikelezweni wesiqandisi, amakhoyili e-evaporator amunca ukushisa ngaphakathi, abangele umswakama osemoyeni ukuba ujiye futhi ube yiqhwa kumakhoyili. Ngokuhamba kwesikhathi, lokhu kwakha ungqimba lwesithwathwa. Ukuze uvimbele ukunqwabelana kwesithwathwa ngokweqile, isibali sikhathi se-defrost noma ibhodi lokulawula lizoqala ngezikhathi ezithile umjikelezo we-defrost, ngokuvamile njalo emahoreni angu-6 kuya kwangu-12, kuye ngemodeli yesiqandisi.
Lapho umjikelezo we-defrost uqalwa, isistimu yokulawula izonqamula i-compressor futhi isebenzedefrost heater. I-current idlula ku-heater, ikhiqiza ukushisa ukufudumeza amakhoyili e-evaporator. Njengoba izinga lokushisa ikhoyili likhuphuka, isithwathwa esinqwabelene siqala ukuncibilika sibe amaconsi amanzi.
Ukuze uvimbele ukulimala kwesistimu nokuqinisekisa ukuncibilika kahle, i-thermostat ye-defrost iqapha izinga lokushisa lekhoyili ye-evaporator. Lapho izinga lokushisa selifinyelele izinga elithile, okubonisa ukuthi isithwathwa sincibilike ngokuphelele, i-thermostat ithumela isignali ohlelweni lokulawula ukuze kumiswe umjikelezo wokuncibilika.
Amanzi akhiwe kwisithwathwa esincibilikayo ageleza ehle kukhoyili ye-evaporator aye epanini lokuconsa elingaphansi kwento esetshenziswayo. Lapho, ngokuvamile liyahwamuka ngenxa yokushisa okukhiqizwa i-compressor phakathi nomjikelezo ovamile wesiqandisi.
Ngakolunye uhlangothi, izinhlelo zokuqeda igesi ezishisayo zivame kakhulu emishinini emikhulu yesiqandisi yezentengiselwano. Kulezi zinhlelo, esikhundleni sokusebenzisa izifudumezi zikagesi, isiqandisi ngokwaso sisetshenziselwa ukuncibilikisa amakhoyili. Phakathi nomjikelezo wokuqothula, uhlelo lwesiqandisi lushintsha isiqondiso salo sokusebenza.
I-valve yethula ngokuqondile izinga lokushisa eliphezulu kanye negesi yesiqandisi yokucindezela okuphezulu ekhishwa ku-compressor iye kwikhoyili ye-evaporator. Njengoba igesi eshisayo igeleza kukhoyili, idlulisela ukushisa kungqimba lwesithwathwa, okubangela ukuba incibilike. Amanzi ancibilikisiwe ayakhanywa. Ngemva kokuphela komjikelezo wokuqeda iqhwa, i-valve iqondisa kabusha isiqandisi emuva kumjikelezo wayo wokupholisa ovamile.
Kungakhathaliseki ukuthi isistimu yokuqeda isithwathwa kagesi noma isistimu yokuqeda isithwathwa yegesi eshisayo, inhloso yabo ukususa ungqimba lwesithwathwa kukhoyili ehwamukayo, kodwa basebenzisa izindlela ezihlukene zokuqeda isithwathwa.
Ukugcinwa okuvamile nokusebenza okuvamile kwe-defrost heater amashubhuzibalulekile ekusebenzeni kahle kwesistimu yesiqandisi. Ukungasebenzi kahle kwe-heater kungase kuholele ekunqwabelaneni kwesithwathwa ngokweqile, ukunciphisa ukusebenza kahle kwesiqandisi, kanye nokulimala okungaba khona emishinini.
Izifudumezi ze-Defrost zidlala indima ebalulekile ekugcineni ukusebenza kahle kwesistimu yesiqandisi ngokuvimbela isithwathwa ukuba simile kumakhoyili e-evaporator. Kungakhathaliseki ukuthi ukushisisa okungazweli noma ukushisisa ngegesi eshisayo, lezi zifudumezi ziqinisekisa ukuthi amakhoyili awashisi ngaphezulu, okuvumela isistimu ukuthi isebenze kahle futhi igcine izinga lokushisa elidingekayo ngaphakathi kwento esetshenziswayo.
