Ama-screw chiller angahlukaniswa abe ama-screw chiller apholile emoyeni kanye nama-screw chiller apholile ngamanzi ngokwezindlela ezahlukene zokushabalalisa ukushisa. I-screw chiller epholile emanzini isebenzisa uhlelo lokujikeleza kwamanzi lombhoshongo wokupholisa ukuze isuse ukushisa, kuyilapho i-screw chiller epholile emoyeni isebenzisa umoya ogobile ukuze isuse ukushisa. Ngesikhathi senqubo yokusebenza kweyunithi, kuzoba nokungcola okuthile ngenxa yekhwalithi yamanzi noma izinkinga zomoya, noma ngoba uwoyela oqandisiwe ungcolile, okuzothinta lonke uhlelo lokuqandisa. Yenza ukuhlanza nokulungisa.
Ngakho-ke, ungahlanza kanjani uhlelo lokuqandisa lwesikulufa sesikulufa?
1. Unganquma kanjani ukuthi uhlelo lokuqandisa lwesikulufo se-screw ludinga ukuhlanzwa?
Okokuqala, kufanele sibheke ukuthi umbala wamafutha kawoyela wokuqandisa we-compressor we-screw chiller uphenduka onsundu yini? Uma kunjalo, kusho ukuthi ikhwalithi kawoyela inamafu. Okwesibili, hlola ukuthi iphunga lishile yini, bese uhlola inani lokumelana kwe-motor winding ku-compressor. Uma inani lokumelana phakathi kwe-winding ne-shell livamile, kusho ukuthi i-insulation ilungile. Ngaphandle kwalokho, uwoyela wokuqandisa kumele ushintshwe futhi uhlelo lokuqandisa kumele luhlanzwe.
Lapha, ngithanda ukukhumbuza wonke umuntu: Ohlelweni lwamanzi lwesitsha sokupholisa, ukungcola kuzonamathela odongeni lwangaphakathi lwepayipi cishe noma kancane. Uma iyunithi isebenza isikhathi eside futhi kunokungcola okuningi kakhulu, isihlungi sokomisa sizovalwa futhi iyunithi ngeke ikwazi ukupholisa. Ngakho-ke, kunconywa ukuhlanza i-heat exchanger njalo ezinyangeni eziyisithupha nokuhlanza uhlelo njalo ngonyaka.
2. Yini okufanele yenziwe ngaphambi kokuhlanza uhlelo lokuqandisa?
Ukuze kungcoliswe ipayipi lesistimu yokuqandisa, i-ejenti yokuhlanza ingasetshenziswa ukuyihlanza. Ngaphambi kokuhlanza, kuyadingeka ukukhulula i-refrigerant ohlelweni lokuqandisa, bese ususa i-compressor, bese uthulula uwoyela we-refrigerant epayipini lenqubo. Ngesikhathi sokusebenza kokuhlanza, qala ususe i-compressor kanye nesihlungi esomile, bese unqamula i-capillary (noma i-expansion valve) ku-evaporator, xhuma i-evaporator ku-condenser ngepayipi elimelana nokucindezela, bese usebenzisa i-A hose uxhuma ngokuqinile imishini yokuhlanza namapayipi okumunca nokukhipha e-compressor. Bese uhlanza imishini esetshenziswayo, njengamaphampu, amathangi, izihlungi, imishini yokomisa, nama-valve ahlukahlukene.
Inqubo yokuhlanza imi kanje: qala ufake i-ejenti yokuhlanza ethangini eliwuketshezi, bese uqala ipompo, uyenze isebenze, bese uqala ukuhlanza. Uma uhlanza, yenza imisebenzi eminingi ngezindlela eziya phambili nezibuyela emuva kuze kube yilapho i-ejenti yokuhlanza ingabonakalisi i-asidi. Uma ungcolisa kancane, idinga ukujikeleza cishe ihora eli-1. Uma ungcolisa kakhulu, kuthatha amahora ama-3-4. Uma ihlanzwa isikhathi eside, i-ejenti yokuhlanza ingcolile, kanti nesihlungi sivalekile futhi singcolile. I-ejenti yokuhlanza kanye nesihlungi kufanele kushintshwe ngaphambi kokwenza lo msebenzi. Ngemva kokuthi uhlelo luhlanziwe, i-ejenti yokuhlanza ingcolile futhi isihlungi sivalekile futhi singcolile. I-ejenti yokuhlanza echibini eliwuketshezi kufanele ilandwe epayipini eliwuketshezi. Ngemva kokuhlanza, ukufutha kanye nokomisa i-nitrogen kufanele kwenziwe epayipini lokuqandisa, bese kugcwaliswa nge-fluorine, futhi umsebenzi wokulungisa amaphutha eyunithi kufanele wenziwe ukuqinisekisa ukusebenza okuvamile kwe-chiller.
Amandla e-screw chiller makhulu kakhulu, futhi kukhona ukukhetha kwekhanda elilodwa noma amabili. I-screw chiller enekhanda elilodwa ine-compressor eyodwa kuphela, engalungiswa ngezigaba ezine kusukela ku-100% kuya ku-75% kuya ku-50% kuya ku-25%. I-screw chiller enekhanda elilodwa yakhiwe ama-compressor amabili futhi inezinhlelo ezimbili ezizimele. Uma enye yazo yehluleka noma idinga ukulungiswa, enye ingasetshenziswa ngokujwayelekile, okulula kakhulu ukuyisebenzisa.
