Phakathi kokuqhubela phambili kwezobuchwepheshe ekufrijini, ukuthembeka, ukuzinza, kunye nokusebenza kakuhle kwee-compressor ze-scroll ezinobushushu obuphantsi kubalulekile ekukhetheni inkqubo. Ii-compressor ze-scroll ze-ZF/ZFI zochungechunge lwe-Copeland ezisebenzisa ubushushu obuphantsi zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya indawo yokugcina izinto ebandayo, iivenkile ezinkulu, kunye novavanyo lokusingqongileyo. Uvavanyo lokusingqongileyo lufuna kakhulu. Ukuphendula ngokukhawuleza kutshintsho lobushushu ngaphakathi kwigumbi lovavanyo, umlinganiselo woxinzelelo oluphakathi kwenkqubo uhlala utshintshatshintsha kakhulu. Xa usebenza kumlinganiselo woxinzelelo oluphezulu, ubushushu bokukhupha i-compressor bunokunyuka ngokukhawuleza bufikelele kumanqanaba aphezulu kakhulu. Oku kufuna ukufakwa kwe-liquid refrigerant kwigumbi loxinzelelo oluphakathi le-compressor ukulawula ubushushu bokukhupha, ukuqinisekisa ukuba luhlala ngaphakathi koluhlu oluchaziweyo kwaye kuthintelwe ukungaphumeleli kwe-compressor ngenxa yokuthambisa okungekho semgangathweni.
Iicompressor zeCopeland ze-ZF06-54KQE ezisebenzisa ubushushu obuphantsi zisebenzisa ivalvu eqhelekileyo ye-DTC liquid injection ukulawula ubushushu bokukhupha. Le valve isebenzisa i-temperature sensor efakwe kwi-cover ephezulu ye-compressor ukuze iqonde ubushushu bokukhupha. Ngokusekelwe kwindawo yokulawula ubushushu bokukhupha esele icwangcisiwe, ilawula ukuvulwa kwevalvu ye-DTC liquid injection, ilungisa ubungakanani be-liquid refrigerant efakwe ukuze kugcinwe ulawulo lobushushu bokukhupha, ngaloo ndlela iqinisekisa ukuthembeka kwe-compressor.
Iicompressor ze-ZF ezinobushushu obuphantsi ezineevalvu zokujova ulwelo ze-DTC
Iicompressor zesizukulwana esitsha seCopeland ze-ZFI09-30KNE kunye ne-ZF35-58KNE ezisebenzisa ubushushu obuphantsi zisebenzisa iimodyuli ze-elektroniki ezikrelekrele kunye neevalvu zokwandisa ze-elektroniki ze-EXV ukuze kulawulwe ngokuchanekileyo inaliti yolwelo. Iinjineli zeCopeland zilungiselele ingqiqo yolawulo lwenaliti yolwelo ukuze kuvavanywe okusingqongileyo ukuze kuhlangatyezwane neemfuno ezahlukeneyo zabathengi. Iivalvu zokwandisa ze-elektroniki ze-EXV zibonelela ngempendulo ekhawulezileyo kwaye zilawula amaqondo obushushu okukhupha i-compressor ngaphakathi koluhlu olukhuselekileyo. Inaliti yolwelo echanekileyo inciphisa ilahleko zokupholisa inkqubo.
Amanqaku aKhethekileyo:
1. ICopeland icebisa ububanzi obufanayo no-R-404 kwiityhubhu ze-capillary ze-R-23 zokufaka ulwelo njengoqwalaselo lokuqala. Oku kusekelwe kumava okusetyenziswa ngokoqobo. Ububanzi kunye nobude bokugqibela obulungisiweyo busafuna ukuvavanywa ngumenzi ngamnye.
2. Ngenxa yomahluko omkhulu kuyilo lwenkqubo phakathi kwabathengi abahlukeneyo, iingcebiso ezingentla zezokusetyenziswa kuphela. Ukuba ityhubhu ye-capillary enobubanzi obuyi-1.07mm ayifumaneki, ububanzi obuyi-1.1-1.2mm bunokuqwalaselwa ukuze kuguqulwe.
3. Kufuneka isihluzo esifanelekileyo phambi kwetyhubhu ye-capillary ukuthintela ukuvaleka kokungcola.
4. Kwizixhobo zokudibanisa uthotho lwe-ZF35-54KNE kunye ne-ZFI96-180KQE zesizukulwana esitsha saseCopeland, ezinee-sensors zobushushu bokukhupha ezakhelwe ngaphakathi kunye neemodyuli ezikrelekrele zesizukulwana esitsha saseCopeland, i-capillary liquid injection ayikhuthazwa. I-Copeland icebisa ukusebenzisa i-valve yokwandisa ye-elektroniki ukujova ulwelo. Abathengi banokuthenga ikhithi yezixhobo zokufaka ulwelo ezizinikeleyo zaseCopeland.
