Isibambisi sefriji sibizwa ngokuthi i-chiller, okuyingxenye ebalulekile yesistimu yokupholisa umoya yesikhungo sedatha. I-refrigerant ngokuvamile ingamanzi, ebizwa ngokuthi i-chiller. Ukupholisa kwe-condenser kutholakala ngokushintshana kokushisa kanye nokupholisa amanzi okushisa ajwayelekile, ngakho-ke kubizwa nangokuthi iyunithi epholiswe ngamanzi. . Isikhungo sedatha sinesidingo esikhulu somthamo wokupholisa, futhi ukusebenza kahle kwamandla okungcono kungatholakala ngokukhetha iyunithi ye-centrifugal. I-chiller kulesi sihloko ibhekisela ngqo kuyunithi ye-centrifugal.
I-compressor yokuqandisa ye-centrifugal iyi-compressor yohlobo lwesivinini esijikelezayo. Ipayipi lokumunca lethula igesi okufanele icindezelwe ingene endaweni yokungena ye-impeller. Igesi ijikeleza ngesivinini esikhulu nge-impeller ngaphansi kokusebenza kwama-blade e-impeller. Igesi iyasebenza, isivinini segesi siyanda, bese ikhishwa endaweni yokuphuma ye-impeller, bese ifakwa ekamelweni le-diffuser; njengoba igesi iphuma ku-impeller, inejubane lokugeleza eliphezulu, ukuze iguqule le ngxenye yejubane ibe amandla okucindezela, kufakwa i-diffuser enesigaba sokugeleza esikhuliswe kancane kancane ukuguqula amandla ukwandisa ingcindezi yegesi; ngemva kokuba igesi esabalele iqoqwe ku-volute, ingena ku-condenser yeyunithi ukuze iqiniswe. Inqubo engenhla i-centrifuge. Umgomo wokucindezela, njengoba kuboniswe kuMfanekiso 1; Ngaphezu kwalokho, ukuze kuqiniswe futhi kususwe ubanda, uhlelo lokupholisa umoya luhlanganisa uhlelo lwamanzi okupholisa kanye nohlelo lwamanzi abandayo.
01
Ukwakheka kweyunithi ye-Centrifugal
Ukwakheka kweyunithi ye-centrifugal kungokulandelayo: kufaka phakathi i-centrifugal compressor, i-evaporator, i-condenser, i-throttling orifice, idivayisi yokuhlinzeka ngowoyela, ikhabhinethi yokulawula, njll., njengoba kuboniswe kuMfanekiso 2 kanye noMfanekiso 3. I-compressor yakhiwe kakhulu yigumbi lokumunca, i-impeller, i-diffuser, i-bend kanye nedivayisi ye-reflux, kanye ne-volute.
Izici zeyunithi ye-centrifugal
Izici zeyunithi enkulu ye-centrifuge yilezi ezilandelayo:
1. Umthamo omkhulu wokupholisa. Njengoba umthamo wokudonsa we-compressor ye-centrifugal ungeke ube mncane kakhulu, umthamo wokupholisa weyunithi eyodwa we-compressor ye-centrifugal mkhulu kakhulu. Isakhiwo esiqinile, isisindo esincane nosayizi omncane, ngakho-ke sithatha indawo encane. Ngaphansi komthamo ofanayo wokupholisa, isisindo se-compressor ye-centrifugal singu-1/5 kuya ku-1/8 kuphela saleso se-compressor ye-piston, futhi lapho umthamo wokupholisa ukhula, kulapho ubonakala khona kakhulu.
2. Izingxenye ezigqokwa kancane kanye nokuthembeka okuphezulu. Ama-compressor e-centrifugal cishe awagugi ngesikhathi sokusebenza, ngakho-ke aqinile futhi anezindleko eziphansi zokulungisa nokusebenza.
3. Ingxenye yokucindezela ku-compressor ye-centrifugal iwukunyakaza okujikelezayo, futhi amandla e-radial alinganisiwe, ngakho-ke ukusebenza kuzinzile, ukudlidliza kuncane, futhi akudingeki idivayisi ekhethekile yokunciphisa ukudlidliza.
4. Umthamo wokupholisa ungalungiswa ngokwezomnotho. Ama-compressor e-centrifugal angasebenzisa izindlela ezifana nokulungiswa kwe-vane yokuqondisa ukulungisa amandla ngaphakathi kobubanzi obuthile.
5. Kulula ukusebenzisa ukucindezela kanye nokucindezela okunezigaba eziningi, futhi kungafeza ukusebenza kanye nokusebenza kwesiqandisi esifanayo esinokushisa okuhlukahlukene kokuhwamuka.
Amaphutha Avamile E-Chillers
Umshini obandayo uzobhekana nezinkinga ezithile ngesikhathi sokwakhiwa nokuqaliswa kokusebenza, futhi kuzophinde kube nokwehluleka ngesikhathi sokusebenza. Ukuphathwa kwalezi zinkinga kanye namaphutha kuhlobene nokuphepha kokusebenza nokugcinwa kwesikhungo sedatha. Lokhu okulandelayo yizimo ezithile ezenzeke ngesikhathi sokwakhiwa nokusebenza kwemishini ebandayo. Izindlela zokucubungula ezifanele kanye nokuhlangenwe nakho kungokwereferensi kuphela.
01
Akukho ukulungisa iphutha lomthwalo
【Inkinga】
Isikhungo sedatha sidinga ukulungisa amaphutha nokuhlola ukusebenzisa i-chiller, kodwa ukufakwa kwemishini yokupholisa umoya esigungwini akukaqedwa, futhi indawo nayo ayinawo umthwalo odingekayo, ngakho-ke umsebenzi wokuyiqalisa awukwazi ukwenziwa.
【ukuhlaziywa kwezinkinga】
Ngemva kokufakwa kweyunithi ye-centrifuge esikhungweni sedatha sekuqediwe, imishini yokugcina egumbini lekhompyutha ayifakwanga, isiteshi samanzi esiqandisayo esigungwini siyavalwa, futhi i-chiller ayikwazi ukususwa amaphutha. Umthwalo mncane kakhulu ukufinyelela umthwalo ophansi we-chiller, futhi umsebenzi wokususa amaphutha awukwazi ukwenziwa. Ngakolunye uhlangothi, ngenxa yokuthi umshini obandayo awususwanga amaphutha, imishini yeseva egumbini eliyinhloko lekhompyutha ayikwazi ukuvulwa nokusebenza, yakha iluphu engapheli komunye nomunye; ngaphezu kwalokho, ngesikhathi senqubo yokususa amaphutha, amandla omthwalo odingekayo makhulu, futhi inqubo yokusebenza izodla amandla amaningi; izici ezingenhla ziholela ekususweni kwamaphutha emshinini obandayo.
【Inkinga ixazululiwe】
Sebenzisa indlela yokulungisa amaphutha ngaphandle kokulayisha ukuze ulungise amaphutha. Le nqubo iwukusebenzisa ngokugcwele amandla okushintshanisa ukushisa kwe-plate exchange, ukushintshanisa ukubanda okukhiqizwa yi-evaporator yesiqandisi ohlangothini lwe-condenser lwesiqandisi ngokusebenzisa i-plate exchange, bese ushintshanisa ukushisa okukhishwe yi-condenser yesiqandisi emuva ohlangothini lwe-evaporator ngokusebenzisa i-plate exchange, ukuze kufezwe ukufana okuphelele phakathi kwamandla okupholisa esiqandisi nomthwalo wokushisa, kanti umbhoshongo wokupholisa ususa amandla omgodi we-compressor kuphela. Ukusebenzisa le ndlela, kulula ukufeza ukuhlolwa kokusebenza okuphelele ngaphansi kwemithwalo ehlukene. Ukujikelezwa kwesekethe yamanzi kokufakwa kwe-cold plate kanye nokulungisa amaphutha kuboniswe kuMfanekiso 4.
Izinyathelo zokulungisa iphutha lesistimu ngokuyisisekelo zimi kanje:
1. Vula i-bypass valve ku-sub-collector, bese uqinisekisa ukuthi umzila wamanzi uvuliwe ukuze ujikeleze lapho i-terminal air conditioner ingafakiwe;
2. Vula ngokuphelele i-chiller ohlangothini lwamanzi abandayo kanye ne-valve yokushintshana kwepuleti ukuqinisekisa ukuthi ukudlula kwamanzi kwe-chiller kanye ne-plate exchange kubushelelezi, futhi amanzi abandayo adonswa yi-chiller kanye nokushisa okubuyiselwa yi-plate exchange kungaxutshwa kahle; ngokuvamile vula iphampu yamanzi abandayo bese ulungisa imvamisa ngesandla ibe ngu-45Hz noma ngaphezulu, futhi uqinisekise ukuthi ukujikeleza kwamanzi kujwayelekile;
3. Vula ngokuphelele ivalvu yamanzi okupholisa ye-chiller, vula kancane ivalvu ohlangothini lwamanzi okupholisa lwephaneli eshintshiwe, bese uvula iphampu yamanzi okupholisa ukuqinisekisa ukujikeleza kwamanzi okuvamile. Lungisa imvamisa yephampu ibe ngu-41-45Hz; ungavuli ifeni yombhoshongo wokupholisa kuqala;
4. Ngaphansi kwezimo ezijwayelekile zamanzi abandayo namanzi okupholisa, vula i-chiller bese wenza umsebenzi wokuzama wodwa;
5. Izinga lokushisa lamanzi abandayo efrijini liqala ukukhuphuka, futhi amanzi abandayo aqala ukuphola;
6. Lungisa umthamo wokudlulisa ukushisa kwe-plate exchange ngokuya ngokuvuleka kwe-valve yamanzi okupholisa ye-plate exchange, bese ulungisa ukuvuleka kwe-valve phakathi kwe-1/4 nokuvuleka ngokuphelele;
7. Vula kancane ifeni yombhoshongo wokupholisa ngokwezinga lokushisa lamanzi okupholisa, noma yikuphi okungasusa amandla omgodi we-compressor.
【Isipiliyoni】
Ukuze kuncishiswe ukusebenza kahle kwamandla futhi kucatshangelwe ukupholisa ngokwemvelo, izikhungo zedatha ngokuvamile zakhiwe ngobuchwepheshe bokupholisa esikhundleni sombhoshongo wokupholisa + ipuleti. Ngesikhathi sokusebenza, amandla okushintshanisa ukushisa kwepuleti angasetshenziswa ukuthola ukushisa okwanele kusuka ku-condenser yesitsha njengoba umthwalo wokushisa wokusebenza kwesitsha, okungukuthi, ubanda obukhiqizwa yi-chiller bususwa yi-plate exchange.
Umgomo wokulungisa iphutha ngaphandle komthwalo ukusebenzisa ngokugcwele amandla okushintshanisa ukushisa kwe-plate exchange, ukushintshanisa ukubanda okukhiqizwa yi-evaporator yesiqandisi ohlangothini lwe-condenser yesiqandisi ngokusebenzisa i-plate exchange, nokushintshanisa ukushisa okukhishwe yi-condenser yesiqandisi kubuyele ku-evaporator ngokusebenzisa i-plate exchange Side, ukuze kufezwe ukulingana kwamandla okupholisa kanye nomthwalo wokushisa wesiqandisi, le ndlela ilula ukuyisebenzisa futhi kulula ukuyisebenzisa.
