Iyini i-Defrost heater?

I-heater ye-defrost iyisici esitholakala ngaphakathi kwesigaba samafriji esiqandisini. Umsebenzi wawo oyinhloko ukuncibilikisa isithwathwa esinqwabelana kumakhoyili e-evaporator, ukuqinisekisa ukusebenza kahle kwesistimu yokupholisa. Uma isithwathwa sinqwabelana kula makhoyili, sikhinyabeza ikhono lesiqandisi ukuphola kahle, okuholela ekusebenziseni amandla aphezulu kanye nokonakala kokudla.

I-heater ye-defrost ngokuvamile ivula ngezikhathi ezithile ukuze yenze umsebenzi wayo omisiwe, okuvumela isiqandisi ukuthi sigcine izinga lokushisa elilungile. Ngokuqonda indima ye-heater ye-defrost, uzohlonyiswa kangcono ukuxazulula izinkinga ezingase ziphakame, ngaleyo ndlela welule isikhathi sokuphila somshini wakho.

Isebenza Kanjani I-heater ye-Defrost?
Indlela yokusebenza ye-heater ye-defrost iyathakazelisa impela. Ngokuvamile, ilawulwa isibali sikhathi sokumisa isiqandisi kanye ne-thermistor. Nakhu ukubuka okujulile kwenqubo:

I-Defrost Cycle
Umjikelezo we-defrost uqalwa ngezikhathi ezithile, ngokuvamile njalo emahoreni angu-6 kuya kwangu-12, kuye ngemodeli yesiqandisi kanye nezimo zemvelo ezisizungezile. Umjikelezo usebenza kanje:

I-Defrost Timer Activation: Isibali sikhathi se-defrost sibonisa ukuthi i-heater ye-defrost ivule.
Ukukhiqiza Ukushisa: Ihitha ikhiqiza ukushisa, okuqondiswe kumakhoyili e-evaporator.
Ukuncibilika Kwesithwathwa: Ukushisa kuncibilikisa isithwathwa esinqwabelene, sisenze sibe amanzi, bese siyaphela.
Ukusethwa Kabusha Kwesistimu: Uma isithwathwa sincibilika, isibali sikhathi sokuncibilika siyacisha i-heater, futhi umjikelezo wokupholisa uqalise kabusha.
Izinhlobo zama-Defrost heater
Kunezinhlobo ezimbili eziyinhloko zama-heaters asetshenziswa eziqandisini:

Ama-heaters kagesi: Lezi zifudumezi zisebenzisa ukumelana nogesi ukuze zikhiqize ukushisa. Ziwuhlobo oluvame kakhulu futhi zitholakala eziqandisini eziningi zesimanje. Izifudumezi zikagesi zokuqeda iqhwa zingaba uhlobo lweribhoni noma uhlobo lwezintambo, eziklanyelwe ukunikeza ukufudumeza okufanayo kuwo wonke amakhoyili e-evaporator.
I-Hot Gas Defrost Heater: Le ndlela isebenzisa igesi ecindezelwe yesiqandisi evela ku-compressor ukukhiqiza ukushisa. Igesi eshisayo iqondiswa ngamakhoyili, incibilikisa isithwathwa njengoba sidlula, okuvumela umjikelezo wokuqeda isithwathwa ngokushesha. Nakuba le ndlela isebenza kahle, ayivamile kakhulu eziqandisini zasendlini kunezifudumezi zikagesi.
