Indlela I-Defrost Heating Element Esebenza Ngayo
Inqubo ye-Defrost Cycle
I-defrost cycle iyinqubo ebalulekile ezinhlelweni zesiqandisi ezivimbela ukunqwabelana kwesithwathwa kumakhoyili e-evaporator. Phakathi nalo mjikelezo, isistimu imisa okwesikhashana ukusebenza kwayo kokupholisa futhi yenze kusebenze into yokushisisa eqeda uqhwa. Le elementi ikhiqiza ukushisa ukuze kuncibilike isithwathwa, iqinisekise ukuthi amakhoyili ahlala engavalekile futhi ekwazi ukumunca ukushisa kahle.
Kumaphampu okushisa, umjikelezo wokuncibilikisa usebenza ngokuhlukile kodwa ufeza injongo efanayo. Ihlehlisa ukusebenza kwephampu lokushisa ukuze kufudumale iyunithi yangaphandle kanye nokuncibilikisa isithwathwa kukhoyili ye-evaporator. Lokhu kuqinisekisa ukuthi isistimu ingakwazi ukumunca ukushisa okuvela emoyeni ongaphandle, ngisho nasesimweni sezulu esibandayo. Ngokugcina amakhoyili acacile, umjikelezo we-defrost usekela ukusebenza okungaguquki kokupholisa nokusebenza kahle kwamandla.
Ukuncibilikisa Isithwathwa Ngokushisa
Idefrosting bafudumale elementidlala indima ebalulekile ekuncibilikiseni isithwathwa ngesikhathi somjikelezo wokuncibilikisa. Njengoba ibekwe eduze kwamakhoyili e-evaporator, ikhipha ukushisa okulawulwayo ukuze iphule iqhwa nesithwathwa esinqwabelana ngokuhamba kwesikhathi. Le nqubo ibuyisela ikhono lamakhoyili okudlulisa ukushisa ngendlela efanele, ivimbele izithiyo zokugeleza komoya nokugcina ukusebenza kahle kokupholisa.
Ukushisa okukhiqizwa isici kulawulwa ngokucophelela ukugwema ukushisa ngokweqile noma ukulimaza izingxenye eziseduze. Izinzwa, njenge-thermistor ye-defrost, ziqapha izinga lokushisa futhi ziqinisekise ukuthi into yokushisisa isebenza ngaphakathi kwemikhawulo ephephile. Lokhu kulawula okunembayo kuvumela isistimu yesiqandisi ukuthi yenze imijikelezo ye-defrost kahle ngaphandle kokuphazamisa ubuqotho bayo besakhiwo.
Ukuhlanganiswa Nezingxenye Zefriji
Isici sokushisa esincibilikayo sihlanganisa ngaphandle komthungo nezinye izingxenye zesiqandisi ukuqinisekisa ukusebenza kahle.

Ukuhlonza lezi zinkinga, ochwepheshe kufanele balandele indlela ehlelekile:
- Hlola iyunithi yangaphandle ukuze uthole iqhwa, iqhwa, noma imfucumfucu engase ivimbe ukugeleza komoya.
- Hlola amakhoyili e-evaporator ukuze uthole ukunqwabelana kweqhwa, okungabonisa izinkinga zokugeleza kwesiqandisi.
- Hlola imigqa yesiqandisi ukuvuza noma ukulimala, njengoba lokhu kungakhinyabeza ukudluliswa kokushisa futhi kuvimbele ukuncibilika okusebenzayo.
Ukubhekana nalezi zindawo kusiza ukukhomba imbangela yokungasebenzi kahle futhi kuqinisekisa ukuthi isici sokushisa esincibilikayo sisebenza kahle.
Ukuhlola kanye Nokuhlonza Izinkinga
Ukuhlonza into engasebenzi kahle yokushisisa i-defrost kudinga ukuhlolwa ngokucophelela. Ochwepheshe bavame ukuqala ngokubheka ngokubona i-elementi yokulimala ngokomzimba, njengokusha noma ukuphuka. Besebenzisa i-multimeter, bangakwazi ukukala ukumelana kwe-elementi ukuze banqume ukuthi isebenza kahle yini. Ukufundwa ngaphandle kwebanga elishiwo ngumkhiqizi ngokuvamile kubonisa iphutha.
I-thermostat ye-defrost ne-thermistor nazo kufanele zihlolwe. Lezi zingxenye zilawula umjikelezo we-defrost futhi ziqinisekisa ukuthi i-elementi isebenza ngesikhathi esifanele. Uma noma iyiphi ingxenye yehluleka, isistimu ingase ingashisi kahle. Ngokuhlola ngokuhlelekile ingxenye ngayinye, ochwepheshe bangahlukanisa inkinga futhi bancome ukulungiswa okufanele.
Ukulungisa noma Ukushintsha Isici
Lapho ai-defrost heat elementilimele ngendlela engenakulungiseka, kudingeka ukushintshwa. Ngaphambi kokushintsha i-elementi, ochwepheshe kufanele banqamule ukunikezwa kwamandla ukuze kuqinisekiswe ukuphepha. Isici esinephutha sibe sesikhishwa, bese kufakwa esikhundleni esihambisanayo. Ukufakwa kahle kuqinisekisa ukuthi into entsha ihlangana kalula nezingxenye zesistimu.
Kwezinye izimo, izinkinga ezincane ezifana nokuxhuma okuxekethile noma izintambo ezinephutha zingalungiswa ngaphandle kokushintsha isici. Ukugcinwa okuvamile nokulungiswa ngesikhathi kwandisa isikhathi sokuphila sesici sokushisa esincibilikayo futhi sithuthukise ukwethembeka okuphelele kwesistimu yesiqandisi.
Izinto zokushisisa eziqeda iqhwa zidlala indima ebalulekile ezinhlelweni zesiqandisi ngokuvimbela ukunqwabelana kwesithwathwa kanye nokuqinisekisa ukusebenza kokupholisa okungaguquki. Ukunakekelwa okuvamile kanye nokuxazulula izinkinga ngesikhathi kuthuthukisa ukusebenza kahle kwazo futhi kwandise isikhathi sokuphila kwemishini. Ithebula elilandelayo ligqamisa izinqubo ezibalulekile ezithuthukisa ukuqina nokusebenza kwesistimu:
| Prakthiza | Zuza |
|---|---|
