Izinto ezisetshenziswa kulezi zici, njenge-nichrome noma i-ceramic, zithinta kakhulu ukusebenza kwazo nokuqina. Isibonelo, i-nichrome inikeza ukuqhutshwa okuphezulu nokudlulisa ukushisa okuphumelelayo, kuyilapho i-ceramic ihlinzeka ngokufakwa kokushisa okuhle kakhulu.
I-Thermostat
I-thermostat idlala indima ebalulekile ekulawuleni izinga lokushisa phakathi nomjikelezo wokuncibilika. Iqinisekisa ukuthi i-elementi yokushisisa iyasebenza futhi yenze ingasebenzi ngezikhathi ezifanele. Kunezinhlobo ezimbalwa zama-thermostats asetshenziswa kuma-heater defrost esiqandisini:
- Ukushintsha kwe-electro-mechanical: Lokhu kuthola ukushintsha kwezinga lokushisa kusetshenziswa imicu yensimbi.
- Izifudumezi Zezinga Lokushisa Ezingezinhle (NTC).: Lokhu kushintsha ukumelana nokuhlukahluka kwezinga lokushisa, kusebenze ukupholisa lapho izinga lokushisa likhuphuka.
- Izihloli Zezinga Lokushisa Ezimelana Nokumelana (ama-RTD): Yenziwe nge-platinum, lezi zibona izinguquko zokushisa ngokuhlukahluka kokumelana.
- Ama-thermocouples: Lezi zisebenzisa izintambo ezimbili zensimbi ukukala izinguquko zezinga lokushisa ngomehluko kagesi.
- Izinzwa Ezisekelwe kuSemiconductor: Lezi zinembe kancane futhi zisetshenziswa kancane.
Uhlobo ngalunye lunezinzuzo nezinkinga zalo, kodwa zonke zinomthelela ekusebenzeni kahle kwe-heater defrost heater.
Control Systems
Amasistimu okulawula abalulekile ekusebenzeni okuthembekile kwezifudumezi ze-defrost. Banquma ukuthi into yokushisa isebenza kanjani futhi nini. Kunezinhlobo ezimbili eziyinhloko zezinhlelo zokulawula: manual kanye ne-othomathikhi.
- Izilawuli ezenziwa ngezandlaidinga abasebenzisi ukuthi baqalise umjikelezo wokususa uqhwa, okungaholela emiphumeleni engahambisani.
- Izilawuli ezizenzakalelayosebenzisa izinzwa nezibali-sikhathi ukuze ulawule umjikelezo wokuqeda iqhwa ngaphandle kokungenelela komsebenzisi.
Ukuhlanganiswa kwalezi zinhlelo zokulawula nesistimu yesiqandisi jikelele kuthuthukisa ukwethembeka. Isibonelo, ucwaningo lubonise ukuthi ukucisha izifudumezi ezimbili ngakunye kungathuthukisa ukusebenza kahle kwe-defrosting15%.
Nakhu ukubuka konke okusheshayo kokuthi izindlela ezihlukene zokulawula zithinta kanjani ukuhlukahluka kwezinga lokushisa nokusebenza kahle:

Ngokuqonda lezi zingxenye, abasebenzisi bangakwazi ukuqonda ukuthi izifudumezi zesiqandisi zisebenza kanjani ukuze zigcine ukusebenza kahle futhi zigweme ukunqwabelana kwesithwathwa.
Ukusebenza Kwezinto Zokushisisa
Izinto zokushisisa zibalulekile ekusebenzeni ngempumelelo kwezifudumezi zokuqeda isiqandisi.Basebenza ukuqeda ukwakheka kwesithwathwa, baqinisekise ukuthi isiqandisi sigcina ukusebenza kahle. Ake sihlole izinhlobo ezahlukene zezinto zokushisa kanyeakhiqiza kanjani ukushisa.
Izinhlobo Zezinto Zokushisisa
Kunezinhlobo eziningana zezinto zokufudumeza zikhona, ngayinye enezici ezihlukile. Nakhu ukubuka konke okusheshayo:
| Uhlobo Lwesici Sokushisa | Ukusebenza kahle Izici |
|---|---|
| Izinto Zokushisisa Ngocingo | Ngokuvamile kungasebenzi kahle ekusabalaliseni ukushisa uma kuqhathaniswa ne-foil ngenxa yendawo engaphansi. |
| Izifudumezi ze-Foil ezifakiwe | Nikeza ukusabalalisa ukushisa okulinganayo nge-heat density enkulungenxa yezikhala eziqinile zezinto zokushisa. |
| I-Resistance Ribbon | Indawo ephezulu nesilinganiso sevolumu ivumela ukukhiqizwa kokushisa okusheshayo, kodwa ubude bempilo bufushane uma buqhathaniswa nentambo. |
Lezi zakhi zokushisisa zidlala indima ebalulekile emjikelezweni wokuncibilika kweqhwa. Isibonelo, i-ribbon yokumelana ishisa ngokushesha, iyenze ilungele ukuqedwa ngokushesha. Ngokuphambene, izinto zokushisisa izintambo zingase zithathe isikhathi eside ukufinyelela izinga lokushisa olifunayo.
Inqubo Yokukhiqiza Ukushisa
Inqubo yokukhiqiza ukushisa kuma-heaters defrost ngokuyinhloko incike ekungangeni kukagesi. Le ndlelaikhiqiza ukushisa ngokusebenzisa izinto eziphikisayo, ngokuvamile ezenziwe ngezinto ezifana ne-Nichrome. Lapho amandla kagesi edlula kulezi zinto, ayashisisa, ancibilikise kahle isithwathwa kumakhoyili e-evaporator.
Izinto zokushisisa kuzifudumezi ze-defrost zibekwe kahle eduze kwamakhoyili e-evaporator. Lokhu kumiswa kuzivumela ukuthi zisebenze futhi zincibilikise ukwakheka kwesithwathwa ngendlela efanele. Ukugeleza komoya ngendlela efanele kubalulekile ukuze kugcinwe ukusebenza kwesiqandisi, futhi lezi zinto zokushisisa zisiza ukuvimbela ukunqwabelana kwesithwathwa ngokweqile.
Intuthuko yakamuva kubuchwepheshe bokushisisa ithuthukise ukusebenza kahle kwamandla. Ngokwesibonelo, iI-Defrost Cycle Control heater isebenzisa izinzwa ukuqapha izinga lokushisa nomswakama. Lesi simiso siqinisekisa ukuthi isifudumezi sisebenza kuphela lapho kudingekile, silondoloza ugesi kuyilapho sigcina ukugcinwa kokudla okufanele.
Ngokuqonda ukusebenza kwezakhi zokushisa, abasebenzisi bangabonga zaboukubaluleka ekugcineni amafrijiegijima kahle.
Iqhaza Le-Thermostat Ekuqedeni Uqhweqhwi
I-thermostat idlala indima ebalulekile enqubweni yokuncibilika kweziqandisi. Isiza ukugcina izinga lokushisa elilungile futhi iqinisekisa ukuthiI-heater ye-defrost isebenza kahle. Ake singene ekutheni ilawula kanjani izinga lokushisa futhi ilawule ukwenziwa kusebenze nokuvala i-heater yokuqeda uqhwebo.
Ukulawulwa kwezinga lokushisa
Ama-thermostat aqapha izinga lokushisa ngaphakathi kwesiqandisi nesiqandisi. Baqinisekisa ukuthi into esetshenziswayo ihlala ngaphakathi kwebanga elithile. Lapho izinga lokushisa likhuphuka ngaphezu kwephoyinti elimisiwe, i-thermostat isayina i-heater ye-defrost ukuthi ivule. Lesi senzo sisiza ukuncibilikisa noma yisiphi isithwathwa noma iqhwa elakhelwe kumakhoyili e-evaporator.
Nazi ezinyeizindlela ezijwayelekile ezisetshenziswa ama-thermostatsukulawula izinga lokushisa:
- Ukwenza kusebenze okusekelwe kusikhathi: I-heater ye-defrost ivula ngezikhathi ezithile.
