Uma iyunithi yokuqandisa isikulufu isiqalisiwe, into yokuqala okufanele uyazi ukuthi uhlelo lokuqandisa lusebenza kahle yini. Okulandelayo isingeniso esifushane kokuqukethwe kanye nezimpawu zokusebenza okuvamile, futhi okulandelayo kungokwereferensi kuphela:
Amanzi okupholisa e-condenser kufanele anele, ingcindezi yamanzi kufanele ibe ngaphezu kuka-0.12MPa, futhi izinga lokushisa lamanzi akufanele libe phezulu kakhulu.
Kumayunithi okuqandisa izikulufo, ukufundwa kwesilinganiso sokucindezela kwephampu kawoyela kufanele kube ngu-0.15~0.3MPa ngaphezu kokucindezela kokukhipha umoya.
Ngaphansi kwanoma yiziphi izimo, izinga lokushisa likawoyela akufanele lidlule u-70°C weyunithi yokuqandisa i-fluorine kanye no-65°C wefriji ye-ammonia, futhi okungenani akufanele kube ngaphansi kuka-30°C. Ngaphansi kwezimo zokusebenza ezijwayelekile, uwoyela wokugcoba akufanele uphole (ngaphandle kweyunithi yokuqandisa i-fluorine).
Izinga lokushisa lokukhipha igesi esiqandisini. I-Ammonia ne-R22 azidluli ku-135°C, futhi uma izinga lokushisa legesi ekhipha umoya likhuphuka kakhulu, lizoba lincane kakhulu uma liqhathaniswa ne-flash point kawoyela oqandisini (160°C), okuyinto engalungile emishinini. Ngakho-ke, ngokombono wokusetshenziswa, izinga lokushisa lokukhipha umoya akufanele libe phezulu kakhulu, futhi uma liphezulu kakhulu, kufanele limiswe ukuze kutholakale isizathu.
Izinga lokucindezela kokujiya. Ngokuyinhloko kunqunywa ngokuya ngomthombo wamanzi, isakhiwo se-condenser kanye nesiqandisi esisetshenziswayo. Izinga loketshezi lwedamu akufanele libe ngaphansi kwengxenye eyodwa kwezintathu zesibonakaliso sezinga loketshezi, futhi izinga likawoyela le-crankcase akufanele libe ngaphansi komugqa ophakathi ovundlile wefasitela lesibonakaliso.
Ipayipi lokubuyisela uwoyela elizenzakalelayo le-fluorine oil separator livamile uma libanda futhi lishisa, kanti umjikelezo obandayo noshisayo cishe uyihora eli-1. Akufanele kube nomehluko ocacile wokushisa ngaphambi nangemva kwesihlungi sepayipi eliwuketshezi. Akufanele kube khona ukuqandisa, ngaphandle kwalokho kuzovinjwa. Isiqandisi se-fluorine kufanele sipholile ohlangothini oluyisicaba futhi sishise ohlangothini olomile. Amalunga esistimu ye-fluorine akufanele avuza uwoyela, okusho ukuthi ukuvuza kwe-fluorine.
Uma uthinta i-condenser evundlile ngesikhathi sokusebenza, ingxenye engenhla kufanele ishise kanti ingxenye engezansi kufanele iphole. Indawo ehlangana kuyo ebandayo neshisayo yizinga loketshezi lwesiqandisi. Isihlukanisi samafutha naso sishisa engxenyeni engenhla, kanti ingxenye engezansi ayishisi kakhulu. I-valve yokuphepha noma i-valve ye-bypass yesiqandisi kufanele izwakale ipholile ekugcineni kokucindezela okuphansi, uma ingapholile, kusho ukuvuza komoya okuphezulu nokuphansi kokucindezela.
Ngesikhathi sokusebenza, ingcindezi yomusi kufanele ifane nengcindezi yokumunca, kanti ingcindezi yokukhipha umoya ekugcineni kwengcindezi ephezulu kufanele ifane nengcindezi yokujiya kanye nengcindezi yesamukeli soketshezi. Uma kungenjalo, akuvamile.
Ngaphansi kwesilinganiso esithile sokugeleza kwamanzi, kufanele kube nomehluko wokushisa phakathi kokungena nokukhipha kwamanzi abandayo. Uma kungekho mehluko wokushisa noma umehluko omncane kakhulu wokushisa, kusho ukuthi indawo yokudlulisa ukushisa yemishini yokushintshanisa ukushisa ingcolile futhi idinga ukuvalwa ukuze ihlanzwe.
Isiqandisi ngokwaso kufanele sivalwe futhi akufanele sivuze isiqandisi namafutha okugcoba. Ukuze kuvikelwe ishaft, uma umthamo ojwayelekile wokupholisa ungu-12.6 × 1000 kJ/h, uphawu lweshaft luvunyelwe ukuba nokuvuza okuncane kwamafutha, kanti isiqandisi esinamandla okupholisa ajwayelekile > 12.6 × 1000 kJ/h asivunyelwe ukuba namaconsi angaphezu kwe-10 okuvuza kwamafutha ngehora. I-Encyclopedia of the fluorine refrigeration unit akufanele kube nokuvuza kwamafutha.
Izinga lokushisa le-shaft seal kanye ne-bearing yesiqandisi akufanele lidlule ku-70°C.
Iqhwa noma amazolo ku-valve yokwandisa kuyafana, kodwa iqhwa elikhulu akufanele livele endaweni yokungena.
