Uhlelo lwesiqandisi luyinkimbinkimbi.

I-4, ukufudumeza kukagesi nokuqeda iqhwa, kusetshenziswa into yokushisa ukushisa indawo ebandayo ukuze kunciphe. Uhlelo lulula, lusebenza kalula, kulula ukulwenza, kodwa ludla amandla amaningi.

izakhi zokushisa ezifakiwe1

Lapho uhlelo lwangempela lunqunywa, ngezinye izikhathi uhlelo lokuqeda iqhwa, futhi ngezinye izikhathi izinhlelo ezahlukene ziyahlanganiswa. Njengepayipi leshalofu lokugcina elibandayo, udonga, ipayipi elibushelelezi eliphezulu, ungasebenzisa inhlanganisela yokwenziwa yendlela yegesi eshisayo, ngokuvamile i-frosting manual, i-hot air defrost evamile, ukuqonda kahle isithwathwa esikhukhumezayo akulula ukususa isithwathwa nokukhipha amafutha. epayipini . I-air blower ishaywa ngamanzi nomoya oshisayo. Ukuze uthole isithwathwa esiningi, ukuncibilika okuvamile kungenziwa ngomoya oshisayo ohlanganiswe nokuncibilika kwamanzi. Uma uhlelo lwesiqandisi sendawo ebandayo lusebenza, izinga lokushisa elingaphezulu le-evaporator livamise ukuba ngaphansi kweziro. Ngakho-ke, i-evaporator ingaphansi kweqhwa, futhi ungqimba lwesithwathwa lunokumelana okukhulu kokushisa, ngakho-ke ukwelashwa okudingekile kwe-defrosting kuyadingeka lapho isithwathwa sishubile.

I-evaporator yesitoreji esibandayo ihlukaniswe ngohlobo lwamapayipi odongeni kanye nohlobo lwe-fin ngokuya ngesakhiwo sawo, uhlobo lokugudluka odongeni ukudluliswa kokushisa kwe-convection yemvelo, uhlobo lwe-fin luphoqelelwa ukudluliswa kokushisa kwe-convection, kanye nendlela yokuqeda iqhwa. ngokuvamile kwenziwa mathupha. Isithwathwa, uhlobo lwe-fin olunokhilimu wokushisa kagesi.

Ukuqedwa kweqhwa okwenziwa ngesandla kuyinkinga kakhulu. Kudingekile ukuthi ukhihlize isithwathwa mathupha, uhlanze isithwathwa, futhi uhambise okuqukethwe komtapo wolwazi. Ngokuvamile, umsebenzisi kufanele ahambe isikhathi eside noma izinyanga ezimbalwa. Lapho i-defrosting, i-frost layer isivele iminyene. Ukumelana okushisayo kwesendlalelo kwenze i-evaporator yaba kude nokuzuza isiqandisi. Ukuncishiswa kokushisisa ngogesi kuyisinyathelo esisodwa esidlula ukuncibilika okwenziwa ngesandla, kodwa kukhawulelwe kuma-evaporator anezinsimbi, izihwaphuzisi zodonga neshubhu azikwazi ukusetshenziswa.
Uhlobo lokushisisa ngogesi kufanele lufakwe eshubhuni yokushisa kagesi ku-evaporator yohlobo lwe-fin, futhi ishubhu lokufudumeza likagesi kufanele lifakwe ethreyini yokwamukela amanzi. Ukuze ususe isithwathwa ngokushesha ngangokunokwenzeka, amandla we-tube yokushisa kagesi ayikwazi ukukhethwa amancane kakhulu, ngokuvamile Kuzoba ama-kilowatts ambalwa. Indlela yokulawula yokusebenza kweshubhu yokushisisa kagesi ngokuvamile ithatha isilawuli sokushisisa isikhathi.
