Izimiso zokukhetha i-compressor yesiqandisi
1) umthamo wokupholisa we-compressor kufanele ukwazi ukuhlangabezana nezidingo zomthwalo ophezulu wesizini yokukhiqiza indawo ebandayo, okungukuthi, umthamo wokupholisa we-compressor kufanele ube mkhulu kunomthwalo womshini noma ulingane nomthwalo womshini. Ngokuvamile ekukhetheni i-compressor, ngokwesizini eshisa kakhulu yonyaka izinga lokushisa lamanzi okupholisa (noma izinga lokushisa) ukuze kunqunywe izinga lokushisa lokuncibilika, izinga lokushisa lokuncibilika kanye nokushisa kokuhwamuka ukuze kunqunywe izimo zokusebenza ze-compressor. Kodwa-ke, umthwalo ophezulu wokukhiqiza indawo ebandayo akwenzeki ukuthi ube sesizini ephezulu kakhulu yokushisa, izinga lokushisa lamanzi okupholisa ekwindla, ebusika nasentwasahlobo (izinga lokushisa) liphansi kakhulu (ngaphandle kwamanzi ajulile emthonjeni), izinga lokushisa lokuncibilika nalo liyancishiswa, umthamo wokupholisa we-compressor uzokhushulwa. Ngakho-ke, ukukhetha i-compressor kufanele kucabangele isici sokulungisa isizini.
2) Kwindawo yokugcina ebandayo encane, njengendawo yokugcina ebandayo yesevisi yokuphila, i-compressor ingakhethwa njengeyunithi eyodwa. Kwindawo yokugcina ebandayo enamandla amakhulu kanye nomthamo omkhulu wokucubungula ebandayo wegumbi lokuqandisa, inani lamayunithi e-compressor akufanele libe ngaphansi kwamabili. Umthamo ophelele wokuqandisa ukuze uhlangabezane nezidingo zokukhiqiza uzonqoba, futhi ngokuvamile awucabangi ngokulinda.
3) uchungechunge lwe-compressor yefriji akufanele ludlule ezimbili, njenge-compressor ezimbili kuphela, uchungechunge olufanayo kufanele lukhethwe ukuze kube lula ukulawula, ukuphatha kanye nokushintshana kwezingxenye ezisele.
4) kwezinhlelo ezahlukene zokushisa ezifakwe ama-compressor, kufanele futhi kucatshangelwe ukuthi kungenzeka yini ukuthi kube nokusekelana phakathi kwamayunithi.
5) Uma i-compressor enedivayisi elawula amandla, ingenza ushintsho olukhulu kumthamo wokupholisa womshini owodwa, kodwa ivumelaniswe nokusebenza kokuguquguquka komthwalo kumthethonqubo, akufanele isetshenziselwe izinguquko zomthwalo wesizini kumthethonqubo. Izinguquko zomthwalo wesizini noma umthamo wokukhiqiza kumthethonqubo womthwalo, kufanele zihlelwe ngokwehlukana ngomthamo wokuqandisa womshini, ukuze kufezwe umphumela ongcono wokonga amandla.
6) Ukuze kuhlangatshezwane nezidingo zenqubo yokukhiqiza, umjikelezo wokuqandisa uvame ukudingwa ukuze kutholakale izinga lokushisa eliphansi lokuhwamuka, ukuze kuthuthukiswe i-coefficient yokulethwa kwe-compressor kanye nokusebenza kahle okubonisiwe, ukuze kuvikelwe ukuphepha kokusebenza kwe-compressor, kufanele kusetshenziswe umjikelezo wokuqandisa wokucindezela wezigaba ezimbili. Isilinganiso sokucindezela kohlelo lokuqandisa lwe-Ammonia i-Pk/P0 sikhulu kuno-8 uma kusetshenziswa ukucindezela kwezigaba ezimbili; Isilinganiso sokucindezela kohlelo lwe-Freon i-Pk/P0 sikhulu kuno-10, ukusetshenziswa kokucindezela kwezigaba ezimbili.
7) Izimo zokusebenza ze-compressor yesiqandisi, akufanele zidlule izimo zokusebenza ezinikezwe umenzi noma amazinga kazwelonke okusebenzisa izimo ze-compressor.
Izimiso ezijwayelekile zokukhetha i-condenser
I-Condenser ingenye yemishini yokudlulisa ukushisa eyinhloko ohlelweni lokuqandisa. Kunezinhlobo eziningi zama-condenser, okubaluleke kakhulu ekukhetheni izinga lokushisa lamanzi, ikhwalithi yamanzi, amanzi kanye nezimo zezulu esifundeni sokwakhiwa komtapo wolwazi, kodwa futhi nokuhlelwa kwezidingo zegumbi, ngokuvamile ngokwemigomo elandelayo okufanele uyikhethe.
1) Ama-condenser apholile ngamanzi aqondile afaneleka ezindaweni ezinemithombo yamanzi eminingi, ikhwalithi yamanzi ephansi kanye nokushisa kwamanzi okuphezulu, futhi ngokuvamile ahlelwe ngaphandle kwegumbi lomshini.
2) Ama-condenser apholile ngamanzi avundlile afaneleka ezindaweni ezinamanzi anele, ikhwalithi enhle yamanzi kanye nokushisa kwamanzi okuphansi, futhi asetshenziswa kabanzi ezinhlelweni ezincane neziphakathi ze-ammonia kanye ne-Freon, futhi ngokuvamile ahlelwe egumbini lemishini yegumbi lomshini.
3) Ama-condenser apholile ngamanzi afaneleka ezindaweni ezinezinga lokushisa eliphansi lomoya, ukutholakala kwamanzi okwanele noma ikhwalithi yamanzi ephansi, futhi ngokuvamile ahlelwe endaweni engaphandle enomoya omuhle.
4) I-evaporative condenser ifanelekela umswakama ophansi kanye nezindawo zokuntuleka kwamanzi, futhi imvamisa itholakala endaweni engaphandle enomoya omuhle.
5) I-condenser epholiswe ngomoya ifaneleka ezindaweni ezinamanzi aqinile kanye nohlelo oluncane lokuqandisa lwe-Freon. Ngokuvamile ayisetshenziswa ezinhlelweni zokuqandisa ze-ammonia.
Ngaphezu kwalokho, ngaphansi kwesimo sokuhlangabezana nezidingo zesistimu, izici ezinjengokuthuthukisa ukusebenza kahle kokudlulisa ukushisa, ukwenza lula ukugcinwa kanye nokunciphisa ukutshalwa kwezimali kokuqala emishinini kufanele kucatshangelwe.
Ukukhethwa kwemigomo ejwayelekile yemishini yokupholisa
Imishini yokupholisa isesimisweni sokuqandisa ukuze ikhiqize umphumela obandayo wemishini yokudlulisa ukushisa enomfutho ophansi ophansi okushisa, esebenzisa uketshezi lwesiqandisi ngokugoqa i-valve ekushiseni okuphansi, imunce ukushisa kwendawo epholile (njenge-brine, umoya), ukuze izinga lokushisa kwendawo epholile linciphe.
Ukukhethwa kwemishini yokupholisa kufanele kunqunywe ngokwezidingo zokucubungula ukudla okubandayo, ukubanda noma ezinye izinqubo, futhi ngokuvamile kufanele kukhethwe ngokwezimiso ezilandelayo.
1) ukusetshenziswa kwemishini yokupholisa ekhethiwe kanye nezimo zobuchwepheshe kufanele kuhambisane nezidingo ezijwayelekile zamanje zemishini yokupholisa yamayunithi okuqandisa.
2) igumbi lokupholisa, igumbi lokuqandisa kanye nemishini yokupholisa ekamelweni lokupholisa kufanele isetshenziselwe ifeni yokupholisa.
3) imishini yokupholisa egumbini lefriji ingakhethwa kusuka ku-exhaust ephezulu, i-offside yodonga kanye ne-chiller. Ngokuvamile uma ukudla kunephakheji enhle, kufanelekile ukusebenzisa i-chiller; ukudla okungenaphakheji enhle, kungasebenzisa ipayipi eliphezulu lokukhipha, ipayipi lokukhipha udonga.
4) ngokuya ngezidingo ezahlukene zenqubo yokuqandisa ukudla ukukhetha imishini yokuqandisa efanele, njengokuqandisa komhubhe, idivayisi yokuqandisa eyisicaba engaphambili, idivayisi yokuqandisa ewuketshezi kanye nedivayisi yokuqandisa ipayipi yohlobo lweshelufu.
5) imishini yokupholisa ekamelweni lokupakisha emazingeni okushisa aphezulu kune-5 ℃ kufanele isetshenziswe lapho kufakwa i-chiller, izinga lokushisa legumbi elingaphansi kwe-59 ℃ kufanele lisetshenziswe lapho kufakwa umugqa wamapayipi.
6) igumbi lokugcina iqhwa elisebenzisa ipayipi elibushelelezi eliseceleni.
