Defrosting izindlela kanye nezindlela zokuphepha zemishini yegumbi ebandayo.

Lapho amazinga okushisa okuhwamuka kohlelo lokugcina amakhaza aphansi kune-0 ° C, kuzovela ungqimba lweqhwa ebusweni be-evaporator, okuthinta ukusebenza kahle kokushisa okushisayo. Ngakho-ke, ukufutheka okujwayelekile kuyingxenye ebaluleke kakhulu yokulungiswa kokugcina okubandayo. Kunezindlela eziningi zokuhlubuka. Njengamanje, abakhiqizi bezokwakha ababandayo ikakhulukazi basebenzisa izindlela ezinhlanu: Ukufakelwa kwe-Defrosting, Ukuqunjelwa kukagesi, ukuqunjelwa komoya okushisayo, i-defrosting yamanzi, i-hot air water defrosting.

1. I-Manual Defrosting ukususa ngesandla isithwathwa ebusweni be-tube yokukhipha i-evaporator. Le ndlela ingenziwa ngaphandle kokumisa imishini yokuqapha. Le ndlela idla isikhathi futhi ilukhuni, futhi umphumela wokuphambuka umpofu.

2. I-Electric Difrosting ukufaka i-heater kagesi ku-evaporator ukuze i-defrost ngokushisa kagesi. Ngesikhathi se-defrosting, yeka i-compressor noma uyeke ukondla uketshezi ku-evaporator. I-Electric Difrosting inezinzuzo zezindleko eziphansi nokulawulwa okulula, kepha izindleko zokuhlinzwa ziphezulu. Ngokuvamile esetshenziselwa ukwehla kwemishini yokugcina ebandayo, hhayi yokuqagela kwemishini yefriji. Kumazinga okushisa ahlukahlukene, izidingo zamakhono wokufakelwa kumele zehluke, futhi amandla okupholisa adingekayo nawo kumele ahluke. Ukusungulwa kwesitoreji esibandayo kudinga ukwenziwa ngokwezifiso ngokuya ngemvelo yohlelo lokusebenza langempela lekhasimende, ngaphandle kokuthi asikho isidingo esikhethekile sokuthatha umgwaqo ojwayelekile.

I-3. Igesi eshisayo eshisayo ukusetshenziswa kweSteam Steam Steam ekhishwe yi-compressor ukukhipha ukushisa ku-evaporator bese kuncibilikisa ungqimba lwesithwathwa ebusweni be-evaporator. Uhlelo olushisayo lwegesi lwe-Defrosting luyinkimbinkimbi futhi izindleko ziphezulu. Kepha umphumela we-defrosting ungcono. Lapho isetshenziswa ohlelweni lwe-ammonia, uwoyela oqongelelwa ku-evaporator nawo angakhishwa endaweni yokuphumula noma ephansi yokujikeleza okuphansi. Enqubweni yegesi eshisayo ye-defrosting, ingcindezi ngokuvamile ilawulwa ku-0.6MPA. Zama ukusebenzisa igesi ephezulu ye-gesi ekhishwe kusuka ku-compressor eyodwa ye-defrosting. Ubusika bungafanelekile ukunciphisa amanzi apholile noma wehlise inani labahlubuki, khuphula izinga lokushisa, nciphisa isikhathi se-defrosting. Okwezinhlelo ze-ammonia, i-ammonia eshisayo ye-defrosting kufanele ixhunywe epayipini eliqeda uwoyela.

I-4. Ukufakelwa kwamanzi ukufiphala amanzi ebusweni be-evaporator ngedivayisi yokufafaza ukuncibilikisa ungqimba lwesithwathwa. Uhlelo lwe-Defrosting lwamanzi lunesakhiwo esiyinkimbinkimbi kanye nezindleko eziphakeme, kepha umphumela omuhle nezindleko eziphansi. Ukuqunjelwa kwamanzi kungasusa kuphela ungqimba lwesithwathwa ebusweni bangaphandle kwe-evaporator, futhi ngeke kuxazulule umphumela omubi wokuqongelela uwoyela ku-everator ekudluliseni kokushisa. Into ebaluleke kakhulu iBhodi Lokwakha elibandayo, elivame ukukhiqizwa ngaphambi komenzi webhodi lokugcina obandayo futhi linobude obuhleliwe, ububanzi nobukhulu. Ibhodi lokugcina elibandayo elingu-100mm livame ukusetshenziselwa isitoreji esibandayo sokushisa esiphakeme nesiphakathi, ibhodi yokugcina ebandayo engu-120mm noma engu-150mm ivame ukusetshenziselwa ukugcinwa okuphansi kokushisa kanye nesitoreji esibandayo.

I-5 Lapho i-defrosting, igesi eshisayo yathunyelwa okokuqala ku-evaporator ukuze ihlukanise ungqimba lwesithwathwa ebusweni be-evaporator, bese amanzi afafazwe ukuze ageze ngokushesha ungqimba lwesithwathwa. Ngemuva kokuthi ukuhanjiswa kwamanzi kunqunywe, ingaphezulu le-evaporator "yomiswe" ngomoya oshisayo ukuvikela ifilimu lamanzi elingaphezulu kusuka ekuqandeni nasekuthinteni ukudluliswa kokushisa. Esikhathini esedlule, abakhiqizi bebhodi lokugcina ababandayo ikakhulukazi basebenzisa i-polyethylene ne-polystyrene njengezinto zokwakha. Manje kukhona ukusebenza okungcono kwe-Polyurethane Sandwich Board. Izibalo zezinto ezibonakalayo ze-Polystyrere Foam insulation ziphansi, azikwazi ukufakwa. Zivame ukusetshenziswa emishini ekhethekile. I-Polyethylene iyinto enhle eluhlaza. Ngokusebenzisa isilinganiso esithile, kungagwetshwa ngenxa yobudala obufanele, umphumela wokufakelwa amandla muhle, ukuthwala okuqinile kwento yokufakelwa. IPolyurethane Plate ingcono, inomsebenzi ongcono wokufakelwa futhi ayimukeli umswakama, kepha le ntengo yokugcina ebandayo iphakeme kancane.
