I-Screw Chillers ingahlukaniswa ibe yi-Screw Screw Screw Chilers kanye nama-Screw-Coled Screw Chillers ngokuya ngezindlela ezahlukahlukene zokuhlanza ukushisa. I-chiller ye-screw yamanzi epholile isebenzisa uhlelo lokujikeleza kwamanzi okupholile ku-Dischitate Ukuqeda ukushisa, ngenkathi umshini wokuphola opholile esebenzisa umoya opholile esebenzisa umoya opholile ukuqeda ukushisa. Ngesikhathi sokusebenza kwe-UNIT, nakanjani kuzoba ukungcola okuthile ngenxa yekhwalithi yamanzi noma izinkinga zomoya, noma ngoba i-oyili efrijiwe iyi-rubid, ezothinta lonke uhlelo lokuqapha. Yenza ukuhlanza nokunakekelwa.
Ngakho-ke, ungakuhlanza kanjani uhlelo lokuqapha kabusha lwe-screw chiller?
1. Unganquma kanjani ukuthi uhlelo lweqandisini lwe-screw chiller ludinga ukuhlanzwa?
Okokuqala, kufanele sikubone ukuthi umbala wamafutha we-ail of refigeration uwoyela wesikulufa chiller uphenduka onsundu? Uma kunjalo, kusho ukuthi ikhwalithi yamafutha inamafu. Okwesibili, hlola ukuthi iphunga lishisiwe, futhi lihlole inani lokumelana lemoto yokuphefumula ku-compressor. Uma inani lokumelana phakathi komoya kanye negobolondo lijwayelekile, kusho ukuthi ukufakwa kulungile. Ngaphandle kwalokho, uwoyela wefriji kufanele ungene esikhundleni futhi uhlelo lweqandi luzohlanzwa.
Lapha, ngithanda ukukhumbuza wonke umuntu: ohlelweni lwamanzi we-chiller, ukungcola kuzonamathela odongeni olungaphakathi lwepayipi noma ngaphansi. Uma iyunithi igijimisa isikhathi eside futhi kukhona ukungcola okuningi kakhulu, isihlungi sokumisa sizovinjwa bese iyunithi ngeke likwazi ukupholisa. Ngakho-ke, kunconywa ukuhlanza i-Exchanger yokushisa njalo ezinyangeni eziyisithupha futhi uhlanze uhlelo njalo ngonyaka.
2. Yini okufanele yenziwe ngaphambi kokuhlanza uhlelo lwefriji?
Ngokungcola epayipi lesihlahla esiyisiqandisi, i-ejenti yokuhlanza ingasetshenziswa ukuyihlanza. Ngaphambi kokuhlanza, kuyadingeka ukudedela esiqandisini ohlelweni wefriji, bese ususa i-compressor, bese ususa uwoyela esiqandisini kusuka epayipi lenqubo. Ngesikhathi sokuhlanza, okokuqala susa i-compressor kanye nesihlungi esomile, bese unqamula i-capillary (noma ukunwebisa i-valve) kusuka ku-evenser, bese usebenzisa i-hose ixhumanisa ngokuqinile imishini yokuhlanza futhi ikhiphe amapayipi okuhlanza. Bese uhlanze imishini esetshenzisiwe, njengamaphampu, amathangi, izihlungi, ezomile, nama-valve ahlukahlukene.
Inqubo yokuhlanza imi ngale ndlela elandelayo: okokuqala faka i-ejenti yokuhlanza ethangini eliwuketshezi, bese uqala iphampu, uqale ukugijima, bese uqala ukuhlanza. Lapho uhlanza, yenza imisebenzi eminingi phambili nangokubuyela emuva kuze kube yilapho umenzeli wokuhlanza engakhombisi i-acidity. Ngokungcola okumnene, kudingeka kuphela ukujikeleza cishe ihora eli-1. Ngokungcola okukhulu, kuthatha amahora ama-3-4. Uma kuhlanzwa isikhathi eside, umenzeli wokuhlanza ungcolile, futhi isihlungi sibuye sivalwe futhi singcolile. Umenzeli wokuhlanza kanye nesihlungi kufanele sithathelwe indawo ngaphambi kokwenza lo msebenzi. Ngemuva kokuthi uhlelo luhlanzwe, i-ejenti yokuhlanza ingcolile futhi isihlungi siyavalwa futhi singcolile. I-ejenti yokuhlanza esihlalweni se-liquid kufanele itholakale kusuka kupayipi we-liquid. Ngemuva kokuhlanza, ukushiswa kwe-nitrogen nokusoma kufanele kwenziwe epayipini lefriji, bese kugcwaliswa nge-fluorine, futhi umsebenzi wokulungisa iphutha weyunithi kufanele wenziwe ukuze uqinisekise ukusebenza okujwayelekile kwe-chiller.
Amandla we-screw chiller ayikhulu, futhi kunokukhethwa kwekhanda elilodwa noma ikhanda eliphindwe kabili. I-chiller yekhanda lekhanda elilodwa ine-compressor eyodwa kuphela, engashintshwa ngezigaba ezine ukusuka ku-100% kuya ku-75% kuya ku-25% kuye ku-25%. I-twin-head screw chiller yakhiwa ama-compressors ama-2 futhi inezinhlelo ezimbili ezizimele. Lapho omunye wabo ehluleka noma edinga ukulungiswa, enye ingasetshenziswa ngokujwayelekile, okulungele ukusetshenziswa.
