Isantya esiphezulu esinesantya esiphezulu semagnethi inverter motor

I-PMSM yokuqala yehlabathi yamandla aphezulu kunye nesantya esiphezulu isetyenziselwa le chiller ye-centrifugal. Amandla ayo angaphezulu kwe-400 kW kwaye isantya sayo sokujikeleza singaphezu kwe-18000 rpm. Ukusebenza kweMoto kungaphezulu kwe-96% kunye ne-97.5% ukuya kowona mgangatho uphezulu, uphezulu kunomgangatho wesizwe webanga loku-1 ekusebenzeni kweemoto. I-compact kwaye ilula. I-400kW yesantya esiphezulu se-PMSM inobunzima obufanayo ne-75kW AC motor induction motor. Ngokwamkela iteknoloji yokupholisa ye-spiral refrigerant yokupholisa i-stator kunye ne-rotor, ubushushu bemoto bunokulawulwa malunga ne-40 ℃, ukuqinisekisa ukusebenza kakuhle.

Isantya esiphezulu semoto esiqhutywa ngokuthe ngqo ngamanqanaba amabiniIyunithi ithatha isantya esiphezulu semoto esiqhutywa ngokuthe ngqo ngamanqanaba amabini. Izixhobo ezikhawulezayo kunye neentsimbi ze-2 ze-radial zikhanseliwe, eziza kuphucula ukusebenza kakuhle kunye nokunciphisa ukulahleka komatshini ubuncinane nge-70%. Ngokuqhuba ngokuthe ngqo kunye nesakhiwo esilula, i-compressor isebenza ngokuthembekileyo kubukhulu obuncinci. Umthamo kunye nobunzima becompressor yi-40% kuphela yomthamo ofanayo wecompressor eqhelekileyo. Ngaphandle kwengxolo ephezulu-frequency yeegiya ezikhawulezayo, isandi sokusebenza kwecompressor sisezantsi kakhulu. Oko kukuthi 8dBA ngaphantsi kuneyunithi eqhelekileyo.
	Yonke imeko yoyilo lwe-pneumatic "wideband". I-Impeller kunye ne-diffuser zilungiselelwe ukuqonda ukusebenza okuphezulu kwecompressor phantsi komthwalo we-25-100%. Xa kuthelekiswa noyilo oluqhelekileyo olusekwe ekusebenzeni komthwalo opheleleyo, olu luyilo lunokunciphisa ukuthomalalisa ukusebenza kakuhle kwecompressor. I-inverter ye-centrifugal chiller eqhelekileyo iqonda amandla olawulo ngesantya esiguqukayo secompressor kunye ne-engile yokuvula eguquguqukayo ye-vane yesikhokelo eqala ukuhla phantsi komthwalo we-50 ~ 60%. Nangona kunjalo, i-Gree CVE uchungechunge lwe-centrifugal chiller inokutshintsha ngokuthe ngqo isantya secompressor phantsi kwe-25 ~ 100% yomthwalo ukunciphisa ilahleko ephazamisayo yesikhokelo kunye nokuphucula ukusebenza phantsi kwazo zonke iimeko.
Kufakwe i-sine-wave inverter Ngokwamkela itekhnoloji yokulawula i-position-sensorless, i-rotor yemoto inokubekwa ngaphandle kwe-probe. Ngetekhnoloji yokulungiswa kwe-PWM elawulekayo, i-inverter inokukhupha i-sine wave egudileyo ukuphucula ukusebenza kwemoto. I-inverter ifakwe ngokuthe ngqo kwiyunithi, ukugcina indawo yomgangatho kubathengi. Ukongeza, zonke iingcingo zonxibelelwano ziqhagamshelwe kumzi-mveliso ukuphucula ukuthembeka kweyunithi.
	I-viscosity ephantsi ye-vane diffuser Uyilo olulodwa lwe-viscosity ephantsi ye-vane diffuser kunye ne-airfoil yesikhokelo i-vane inokuguqula igesi enesantya esiphezulu ibe yigesi ephezulu yoxinzelelo oluphezulu ngokufanelekileyo ukuze iqonde ukuchacha koxinzelelo. Ngaphantsi komthwalo oyinxenye, i-vane diversion inciphisa ilahleko yokubuyela umva, iphucula ukusebenza komthwalo kancinane, kwaye yandisa uluhlu lokusebenza lweyunithi.
Itekhnoloji yoxinzelelo lwamanqanaba amabini Xa kuthelekiswa nenkqubo yefriji yenqanaba elinye, ukunyanzeliswa kwamanqanaba amabini kuphucula ukusebenza kakuhle kokujikeleza nge-5%～6%. Isantya sokujikeleza kweCompressor sithotywa ukuze icompressor ithembeke ngakumbi kwaye yomelele.
	Umgangatho ophezulu we-hermetic impeller I-Compressor impeller yi-ternary hermetic impeller, esebenza ngakumbi kwaye inokwethenjelwa kune-impeller engagqunywanga. Yamkela i-airfoil 3-dimensional structure ukuze ikwazi ukuziqhelanisa ngakumbi. Ngokusebenzisa uhlalutyo lwento elinganiselweyo, umatshini wokuhlola olungelelanisiweyo we-3, uvavanyo oluguquguqukayo lokulinganisa, uvavanyo olungaphezulu kwesantya kunye novavanyo lokwenyani phantsi kwemeko yokwenyani yokusebenza, kuyaqinisekiswa ukuba i-impeller iyahlangabezana neemfuno zoyilo kwaye iyakwazi ukusebenza ngokuzinzileyo. I-Impeller kunye nesiseko se-shaft yamkela uqhagamshelo olungenasitshixo, olunokuthi luthintele uxinzelelo oluyinxenye kunye ne-rotor's additive off-balance ebangelwa luqhagamshelo olungundoqo, ngaloo ndlela iphucula ukuzinza kokusebenza kwecompressor.
Umtshintshi wobushushu ophezulu Umphezulu wokutshintsha ubushushu uyilwe ngokusekelwe kwindlela yokuhambisa ubushushu. Ilungiselelwe ukunciphisa ukulahleka koxinzelelo oluhambayo kunye nokusetyenziswa kwamandla. I-sub-cooler ixhotyiswe emazantsi e-condenser. Ngezithintelo zokuqukuqela ezininzi, idigri yokupholisa encinci inokufikelela kwi-5 ℃. Ibhodi yokwahlula ephakathi ithatha umbhobho wokukhanya ophindwe ngokuphindwe kabini kunombhobho othungelweyo ukuba udityaniswe nebhodi exhasayo, ngoko ke, umbhobho wobhedu awusayi konakaliswa phantsi kweempembelelo zefriji yesantya esiphezulu. Uyilo lweplate yetyhubhu ye-3-V yamkelwa ukuba iqinisekise isiphumo sokutywinwa.
	Iqonga lolawulo oluphezulu Ukusebenza okuphezulu kwe-32-bit CPU kunye neprosesa yesignali yedijithali ye-DSP isetyenziswa. Ukuchaneka kokuqokelela idatha ephezulu kunye nomthamo wokucubungula idatha kuqinisekisa uphawu lwexesha langempela kunye nokuchaneka kolawulo lwenkqubo. Kunye nescreen esichukumisayo se-LCD esinemibala, umsebenzisi unokuqonda ngokulula ulawulo lwe-auto kunye nolawulo lwemanuwali kwi-debugging. Ikwamkele i-algorithm yolawulo lwe-Fuzzy-PID ekrelekrele, edityaniswe nobuchwephesha obukrelekrele, itekhnoloji ye-fuzziness kunye ne-algorithm yokulawula ye-PID eqhelekileyo, ukuze loo nkqubo ikwazi ukusabela ngokukhawuleza kunye nokusebenza okuzinzileyo.
