Isivinini esiphezulu se-inverter motor yesivinini esiphezulu

I-PMSM yokuqala enamandla amakhulu emhlabeni nejubane elikhulu lomhlaba isetshenziselwa le chiller ye-centrifugal. Amandla ayo angaphezulu kuka-400 kW kanti ijubane layo lokujikeleza lingaphezu kuka-18000 rpm. Ukusebenza kahle kwezimoto kungaphezulu kwama-96% no-97.5% kuya phezulu, kuphakeme kunebanga 1 likazwelonke elijwayelekile ekusebenzeni kwezimoto. Ihlangene futhi ayisindi. I-PMSM enejubane eliphezulu engu-400kW inesisindo esifanayo ne-75kW AC motor induction. Ngokusebenzisa ubuchwepheshe bokupholisa bokupholisa bokupholisa bokupholisa phansi i-stator ne-rotor, izinga lokushisa kwemoto lingalawulwa cishe ku-40 ℃, kuqinisekiswe ukusebenza kahle.

Isivinini esikhulu esishayelwa yimoto esinezigaba ezimbiliIyunithi isebenzisa isivinini esikhulu semoto esishayelwa ngokuqondile esinezigaba ezimbili. Amagiya okusheshisa namabhere e-radial ama-2 akhanseliwe, okuzokwenza ngcono ukusebenza kahle futhi kunciphise ukulahleka kwemishini okungenani ngama-70%. Ngokushayela okuqondile nokwakhiwa okulula, icompressor isebenza ngokuthembekile ngosayizi omncane. Ivolumu nesisindo se-compressor yi-40% kuphela yomthamo ofanayo we-compressor ejwayelekile. Ngaphandle komsindo wemvamisa ephezulu yamagiya asheshisa, umsindo wokusebenza we-compressor uphansi kakhulu. Lokho kungu-8dBA ngaphansi kunento ejwayelekile.
	Idizayini yomoya ye- "wideband" yesimo sonke Impeller ne-diffuser zenzelwe ukubona ukusebenza kahle kwe-compressor ngaphansi komthwalo ongu-25-100%. Uma kuqhathaniswa nokuklanywa okuvamile okususelwa ekusebenzeni okugcwele komthwalo, lo mklamo unganciphisa ukunciphisa ukusebenza kahle kwe-compressor. I-inverter chilr centrifugal chiller iqaphela ukulawulwa kwamandla ngejubane eliguqukayo le-compressor kanye ne-angle yokuvula eguquguqukayo ye-vane vane eqala ukwehla ngaphansi komthwalo ongu-50 ~ 60%. Kodwa-ke, i-Gree CVE series chilr centrifugal chiller ingashintsha ngqo ijubane le-compressor ngaphansi kwama-25 ~ 100% umthwalo ukunciphisa ukulahleka kwe-throttling kwe-vane vane futhi kuthuthukise ukusebenza kokusebenza ngaphansi kwazo zonke izimo.
Kufakiwe sine-wave inverter Ngokwamukela ubuchwepheshe bokulawula obungenantambo, i-Rotor yezimoto ingabekwa ngaphandle kophenyo. Ngobuchwepheshe bokulungisa obulawulwa yi-PWM, i-inverter ingakhipha igagasi elibushelelezi le-sine ukuthuthukisa ukusebenza kahle kwezimoto. Inverter ifakwe ngqo kuyunithi, yonga isikhala saphansi kumakhasimende. Ngaphezu kwalokho, zonke izintambo zokuxhumana zixhunywe efektri ukwenza ngcono ukuthembeka kweyunithi.
	Isisabalalisi se-viscosity ephansi Idizayini eyingqayizivele ye-viscosity vane diffuser design kanye ne-airfoil guide vane ingaguqula igesi esheshayo ibe yigesi ephezulu yengcindezi eyi-static ukuze kubonakale ukuvuselelwa kwengcindezi. Ngaphansi kokulayishwa okuyingxenye, ukuphambukisa kwe-vane kunciphisa ukulahleka kokuphuma emuva, kuthuthukisa ukusebenza komthwalo omncane, futhi kunwebe ububanzi bokusebenza kweyunithi
Ubuchwepheshe besigaba sokucindezela esinezitezi ezimbili Uma kuqhathaniswa nesistimu eyodwa yefriji yesigaba esisodwa, ukuminyaniswa kwesigaba ezimbili kuthuthukisa ukusebenza kahle kokujikeleza nge-5% ～ 6%. Ijubane lokujikeleza le-compressor lehliswa ukuze i-compressor ithembeke futhi iqine ngokwengeziwe.
	Ukusebenza kahle kwe-hermetic impeller Icompressor impeller yisiphepheli se-hermetic se-ternary, esisebenza kahle futhi esinokwethenjelwa kune-impeller engamboziwe. Yamukela isakhiwo sezindiza esinezinhlangothi ezintathu ukuze sikwazi ukuguquguquka. Ngokuhlaziywa okuphelele kwezinto, umshini wokuhlola o-3-coordinate, isivivinyo sokulinganisa esinamandla, isivivinyo esisheshayo nokuhlolwa kwangempela ngaphansi kwesimo sokusebenza sangempela, kwenziwa isiqiniseko sokuthi impeller ihlangabezana nemfuneko yokuklama futhi iyakwazi ukusebenza ngokuzinzile. I-impeller ne-shaft eyisisekelo yamukela ukuxhumana okungenalukhiye, okungagwema ukugxila kwengcindezi kanye ne-rotor's add-off-balance ebangelwa ukuxhumana okuyisihluthulelo, ngaleyo ndlela kuthuthukise ukuqina kokusebenza kwe-compressor.
Ukushisa okuphezulu kokushisa okuphezulu Indawo yokushintshanisa ukushisa yakhelwe ngokususelwa kunqubo yokudlulisa ukushisa. Kwenzelwe ukunciphisa ukunciphisa ukulahleka kwengcindezi nokusetshenziswa kwamandla. I-sub-cooler ifakwe ezansi kwe-condenser. Ngokuvinjelwa kokugeleza okuningi, i-sub-cooling degree ingaba ku-5 ℃. Ibhodi elihlukanisa phakathi lithatha ipayipi elilula elijiyile kabili njengepayipi elinezintambo ukuhlanganiswa nebhodi elisekelayo, ngakho-ke, ipayipi lethusi ngeke lilimale ngaphansi komthelela wefriji esheshayo. Idizayini yepuleti engu-3-V embozwe yamukelwa ukuqinisekisa ukusebenza komphumela.
	Ipulatifomu yokulawula okuthuthukile Kusetshenziswa iprosesa yesiginali yedijithali esebenza kahle kakhulu engama-32-bit CPU kanye ne-DSP. Ukunemba okuphezulu kokuqoqwa kwedatha namandla wokucubungula idatha kuqinisekisa isici sesikhathi sangempela nokunemba kokulawulwa kwesistimu. Kanye nesikrini sokuthinta se-LCD esimibalabala, umsebenzisi angabona kalula ukulawula okuzenzakalelayo nokulawula mathupha ekususeni amaphutha. Iphinde yamukele i-algorithm ehlakaniphile yokulawula i-Fuzzy-PID, ehlanganiswe nobuchwepheshe obuhlakaniphile, ubuchwepheshe be-fuzziness kanye ne-algorithm ejwayelekile yokulawula i-PID, ukuze uhlelo lukwazi ukushesha isivinini sokuphendula nokusebenza okuzinzile.
