Uma izinga lokushisa lokuhwamuka kohlelo lokuqandisa indawo ebandayo liphansi kune-0 ° C, kuzovela ungqimba lwesithwathwa ebusweni be-evaporator, okuthinta ukusebenza kahle kokudlulisa ukushisa. Ngakho-ke, ukuqandisa njalo nakho kuyingxenye ebaluleke kakhulu yokugcinwa kwendawo ebandayo. Kunezindlela eziningi zokuqandisa. Njengamanje, abakhiqizi bezakhiwo zezindawo ezibandayo basebenzisa kakhulu izindlela ezinhlanu: ukuqandisa okwenziwe ngokwenziwa, ukuqandisa ngogesi, ukuqandisa emoyeni oshisayo, ukuqandisa ngamanzi, ukuqandisa amanzi emoyeni oshisayo.
1. Ukuncibilikisa iqhwa ngesandla ukususa ngesandla ungqimba lwesithwathwa ebusweni bepayipi lokukhipha i-evaporator. Le ndlela ingenziwa ngaphandle kokumisa imishini yokuqandisa. Le ndlela idla isikhathi futhi inzima, futhi umphumela wokuncibilikisa awulungile.
2. Ukuncibilikisa ugesi ukufaka isifudumezi sikagesi ku-evaporator ukuze sincibilikise ngokushisa kukagesi. Ngesikhathi sokuncibilikisa, misa i-compressor noma uyeke ukunikeza uketshezi ku-evaporator. Ukuncibilikisa ugesi kunezinzuzo zezindleko eziphansi kanye nokulawula okulula, kodwa izindleko zokusebenza ziphezulu. Ngokuvamile kusetshenziselwa ukuncibilikisa imishini yokugcina ebandayo, hhayi ukuncibilikisa imishini yokuqandisa. Kumazinga okushisa ahlukene, izidingo zamakhono okuvikela kumele zihluke, futhi amandla okupholisa adingekayo kumele nawo ahluke. Ukusungulwa kwendawo yokugcina ebandayo kudinga ukwenziwa ngokwezifiso ngokuya ngendawo yokusebenza yangempela yekhasimende kanye nokusetshenziswa kwayo, ngaphandle kokuthi kungekho sidingo esikhethekile sokuthatha indlela yokuma.
3. Ukuncibilikisa igesi eshisayo ukusetshenziswa komusi oqandisiwe oshiswa kakhulu yi-compressor ukuze kukhishwe ukushisa ku-evaporator futhi kuncibilikise ungqimba lwesithwathwa ebusweni be-evaporator. Uhlelo lokuncibilikisa igesi eshisayo luyinkimbinkimbi futhi izindleko ziphezulu. Kodwa umphumela wokuncibilikisa ungcono. Uma kusetshenziswa ohlelweni lwe-ammonia, uwoyela oqoqwe ku-evaporator ungaphinde ukhishwe ungene emgodini wokudonsa amanzi noma endaweni yokujikeleza ephansi. Enkambisweni yokuncibilikisa igesi eshisayo, ingcindezi ngokuvamile ilawulwa ku-0.6MPa. Zama ukusebenzisa igesi enomfutho ophezulu ekhishwe ku-compressor yesigaba esisodwa ukuze uncibilikise. Ubusika bungafaneleka ukunciphisa amanzi okupholisa noma ukunciphisa inani lama-condenser, ukwandisa izinga lokushisa lokukhipha umoya, ukunciphisa isikhathi sokuncibilikisa. Ezinhlelweni ze-ammonia, i-ammonia eshisayo yokuncibilikisa kufanele ixhunywe kumbhobho wokukhipha umoya wesihlukanisi samafutha.
4. Ukuncibilikisa amanzi kuwukufafaza amanzi ebusweni bomshini wokufudumeza ngedivayisi yokufafaza ukuze kuncibilikiswe ungqimba lwesithwathwa. Uhlelo lokuncibilikisa amanzi lunesakhiwo esiyinkimbinkimbi nezindleko eziphezulu, kodwa lunomphumela omuhle nezindleko eziphansi. Ukuncibilikisa amanzi kungasusa kuphela ungqimba lwesithwathwa ebusweni bangaphandle bomshini wokufudumeza, futhi akukwazi ukuxazulula umphumela omubi wokuqongelela uwoyela kumshini wokufudumeza ekudlulisweni kokushisa. Into ebaluleke kakhulu ibhodi lokugcina izinto ezibandayo, elivame ukukhiqizwa kusengaphambili ngumkhiqizi webhodi lokugcina izinto ezibandayo futhi linobude obungaguquki, ububanzi kanye nobukhulu. Ibhodi lokugcina izinto ezibandayo elinobukhulu obuyi-100mm livame ukusetshenziselwa ukugcina izinto ezibandayo ezinokushisa okuphezulu nokuphakathi, ibhodi lokugcina izinto ezibandayo elinobukhulu obuyi-120mm noma obuyi-150mm livame ukusetshenziselwa ukugcina izinto ezibandayo ezinokushisa okuphansi kanye nokugcina izinto ezibandayo.
5. Ukuncibilikisa amanzi emoyeni oshisayo kuyindlela ezimbili zokuncibilikisa okushisayo kanye nokuncibilikisa amanzi ezisetshenziswa ngesikhathi esisodwa, ezigxila izinzuzo zazo zombili, futhi zingasusa ngokushesha nangokuphumelelayo ungqimba lwesithwathwa ebusweni be-evaporator futhi ziqede ukunqwabelana kwamafutha ngaphakathi kwe-evaporator. Lapho kuncibilikiswa, igesi eshisayo ithunyelwa kuqala ku-evaporator ukuze ihlukanise ungqimba lwesithwathwa ebusweni be-evaporator, bese amanzi efafazwa ukuze kugezwe ngokushesha ungqimba lwesithwathwa. Ngemva kokuba amanzi enqanyuliwe, ubuso be-evaporator "buyomiswa" ngomoya oshisayo ukuvimbela ifilimu yamanzi angaphezulu ukuthi ingabi yisithwathwa futhi kuthinte ukudluliselwa kokushisa. Esikhathini esidlule, abakhiqizi bebhodi lokugcina izinto ezibandayo babesebenzisa kakhulu i-polyethylene ne-polystyrene njengezinto zokwakha. Manje sekukhona ukusebenza okungcono kwebhodi lesandwich le-polyurethane. Ubuningi bezinto zokufaka i-polystyrene foam buphansi, abukwazi ukuncibilikiswa. Ngokuvamile zisetshenziswa emishinini ekhethekile. I-Polyethylene iyinto eluhlaza enhle. Ngesilinganiso esithile, ingakhishwa nge-foam ngaphandle kobuningi obufanele, umphumela wokufaka i-insulation muhle, amandla okuthwala aqinile ezinto zokufaka i-insulation. Ipuleti le-polyurethane lingcono, linomsebenzi ongcono wokuvikela futhi alimunci umswakama, kodwa le ntengo yokugcina ebanda iphakeme kancane.
