Mkulu-liwiro okhazikika maginito synchronous inverter galimoto

PMSM yoyamba padziko lapansi yamphamvu kwambiri komanso yothamanga kwambiri imagwiritsidwa ntchito pachilumbachi. Mphamvu zake ndizoposa 400 kW ndipo liwiro lake lozungulira ndiloposa 18000 rpm. Kuyendetsa bwino kwamagalimoto kuli pamwamba pa 96% ndi 97.5% kufikira pazipita, kupitilira muyezo wadziko lonse 1 pamayendedwe apamagalimoto. Ndi yaying'ono komanso yopepuka. PMSM yothamanga kwambiri ya 400kW imalemera chimodzimodzi ndi 75kW AC induction motor. Pogwiritsa ntchito makina ozizira ozizira ozizira kuti aziziziritsa stator ndi ozungulira, kutentha kwa mota kumatha kuwongoleredwa mozungulira 40 ℃, kuwonetsetsa kuti ikugwira ntchito bwino.

Magalimoto othamanga kwambiri othamangitsidwa ndimayendedwe awiriUnit imagwiritsa ntchito magalimoto othamanga kwambiri oyendetsa magawo awiri. Magiya othamangitsa ndi mayendedwe awiri ozungulira achotsedwa, zomwe zithandizira kuchita bwino ndikuchepetsa kutayika kwamakina osachepera 70%. Ndi galimoto mwachindunji ndi dongosolo losavuta, kompresa ntchito molondola mu kukula ang'onoang'ono. Voliyumu ndi kulemera kwa kompresa ndi 40% yokha yofanana ndi kompresa wamba. Popanda phokoso lamphamvu lamagalimoto othamanga kwambiri, phokoso la kompresa ndilotsika kwambiri. Izi ndizochepera 8dBA kuposa chinthu wamba.
	Mpweya wampweya wa "wideband" Impeller ndi diffuser ndizokometsedwa kuti zizindikire magwiridwe antchito a kompresa pansi pa 25-100% katundu. Poyerekeza ndi kapangidwe kabwinoko kamene kamakhala kogwirira ntchito yonse, kapangidwe kameneka kangachepetse mphamvu ya kompresa. Ochiritsira inverter centrifugal chiller amazindikira kuwongolera mphamvu ndi liwiro losinthika la kompresa ndi mawonekedwe oyambira osinthika a vane omwe amayamba kutsika pansi pa 50 ~ 60% katundu. Komabe, Gree CVE mndandanda wa centrifugal chiller amatha kusintha mwachangu liwiro la kompresa pansi pa 25 ~ 100% katundu kuti muchepetse kutaya kwa otsogolera ndikuwongolera magwiridwe antchito munthawi zonse.
Inverter ya sine-wave inverter Pogwiritsa ntchito ukadaulo wowongolera wopanda mphamvu, ozungulira wamagalimoto amatha kukhala opanda kafukufuku. Ndiukadaulo wowongolera womwe ungagwiritsidwe ntchito ndi PWM, inverter imatha kutulutsa mawonekedwe osalala a sine kukonza magwiridwe antchito. Inverter imayikidwa mwachindunji pa chipindacho, ndikupulumutsa malo apansi kwa makasitomala. Kuphatikiza apo, mawaya onse olumikizirana amalumikizidwa mufakitore kuti adalitse kudalirika kwa mayunitsi.
	Kutulutsa kotsika kotsika kotsika Mapangidwe apadera a viscosity vane diffuser kapangidwe kake ndi ma airfoil otsogolera omwe amatha kutulutsa mpweya wothamanga kwambiri kuti ukhale mpweya wambiri wamagetsi kuti athe kuzindikira kupuma. Pakatundu pang'ono, kupatutsa kwa vane kumachepetsa kuchepa kwammbuyo, kumathandizira magwiridwe antchito pang'ono, ndikulitsa magwiridwe antchito a unit
Tekinoloje yapa magawo awiri Poyerekeza ndi dongosolo la gawo limodzi la firiji, kupanikizika kwa magawo awiri kumathandizira magwiridwe antchito moyenera ndi 5% ～ 6%. Compressor rotational liwiro imatsitsidwa kuti kompresa ikhale yodalirika komanso yolimba.
	Kuthamanga kwambiri kwa hermetic impeller Kompresa kompresa ndi ternary hermetic impeller, yomwe imagwira bwino ntchito komanso yodalirika kuposa malo osatsekedwa. Imagwiritsa ntchito njira yolowera mbali ziwiri kuti izitha kusintha. Kupyolera mu kusanthula kocheperako, makina oyang'anira oyang'anira 3, kuyesa koyeserera, kuyesa kuthamanga kwambiri komanso kuyesa kwenikweni pakakhala magwiridwe antchito, zimatsimikizika kuti zosunthira zimakwaniritsa zofunikira pakupanga ndipo zimatha kugwira ntchito molimbika. Impeller ndi shaft yoyambira imagwiritsa ntchito kulumikizana kopanda tanthauzo, komwe kumatha kupewa kupsinjika pang'ono ndi zozungulira za rotor zomwe zimayambitsidwa ndi kulumikizana kofunikira, potero kumathandizira kukhazikika kwa kompresa.
Mkulu-dzuwa kutentha exchanger Kutentha kosinthasintha kumapangidwa potengera makina osinthira kutentha. Amakonzedweratu kuti achepetse kuthamanga kwakanthawi komanso kugwiritsa ntchito mphamvu. Sub-ozizira imakhala pansi pa condenser. Ndi zoletsa zingapo kutuluka, digiri yozizira kwambiri itha kukhala mpaka 5 ℃. Middle board yodzipatula imagwiritsa ntchito chitoliro chowirikiza kawiri ngati chitoliro cholumikizidwa kuti chilumikizidwe ndi bolodi lothandizira, chifukwa chake, chitoliro chamkuwa sichidzawonongeka chifukwa cha refrigerant yothamanga kwambiri. 3-V yokhotakhota chubu kapangidwe kamene kamasinthidwa kuti katsimikizire kusindikiza.
	MwaukadauloZida ulamuliro nsanja Mapulogalamu apamwamba kwambiri a 32-bit CPU ndi DSP digito. Kusanthula kwakutali kwakusanja ndi kusanja kwachidziwitso kumatsimikizira zenizeni zenizeni komanso kuwongolera kwadongosolo. Pamodzi ndi zojambula zokongola za LCD, wogwiritsa ntchito amatha kuzindikira kuwongolera kwamagalimoto ndikuwongolera pamanja pakukonza njira. Ikugwiritsanso ntchito nzeru zowononga zamagetsi-PID, zomwe zimaphatikizidwa ndi ukadaulo waluso, ukadaulo wosasunthika komanso magwiridwe antchito a PID, kuti dongosololi litha kuyankha mwachangu komanso kukhazikika.
