Liwiro lokhazikika lokhazikika maginito synchronous inverter motor

PMSM yoyamba padziko lonse yamphamvu kwambiri komanso yothamanga kwambiri imagwiritsidwa ntchito pozizira centrifugal. Mphamvu yake ndi yoposa 400 kW ndipo kuthamanga kwake kumadutsa 18000 rpm. Kugwira ntchito bwino kwagalimoto kumakhala pamwamba pa 96% ndi 97.5% mpaka pamlingo waukulu, wapamwamba kuposa mulingo wamtundu wamtundu woyamba wamagalimoto. Ndi yaying'ono komanso yopepuka. PMSM yothamanga kwambiri ya 400kW imalemera mofanana ndi 75kW AC induction motor. Potengera ukadaulo woziziritsa wa spiral refrigerant spray kuti uzizizire stator ndi rotor, kutentha kwa mota kumatha kuyendetsedwa mozungulira 40 ℃, kuwonetsetsa kuti ikugwira ntchito bwino.

Magalimoto othamanga kwambiri oyendetsedwa ndi magawo awiriUnit utenga high-liwiro galimoto molunjika-gawo ziwiri impeller. Magiya othamanga kwambiri ndi ma 2 ma radial bearings amathetsedwa, zomwe zingapangitse kuti ntchitoyo ikhale yabwino ndikuchepetsa kuwonongeka kwa makina ndi 70%. Ndi drive yolunjika komanso mawonekedwe osavuta, kompresa imagwira ntchito modalirika mukukula kocheperako. Volume ndi kulemera kwa kompresa ndi 40% yokha ya mphamvu yofanana wamba kompresa. Popanda phokoso lapamwamba la magiya othamanga, mawu ogwiritsira ntchito compressor ndi otsika kwambiri. Izi ndi 8dBA zochepa kuposa mayunitsi wamba.
	Mapangidwe a pneumatic amtundu uliwonse "wideband". Ma Impeller ndi diffuser amakonzedwa kuti azitha kugwira bwino ntchito ya compressor pansi pa 25-100% katundu. Poyerekeza ndi mapangidwe ochiritsira omwe amatengera kuchuluka kwa katundu, kapangidwe kameneka kamatha kuchepetsa mphamvu ya kompresa. Ma inverter centrifugal chiller amazindikira kuwongolera kwa mphamvu ndi liwiro losinthika la kompresa ndi mawonekedwe otseguka a kalozera vane omwe amayamba kutsika pansi pa katundu wa 50-60%. Komabe, Gree CVE mndandanda wa centrifugal chiller amatha kusintha mwachindunji liwiro la kompresa pansi pa 25 ~ 100% katundu kuti achepetse kutayika kwa chiwongolero cha vane ndikuwongolera magwiridwe antchito pansi pamikhalidwe yonse.
Anaika sine-wave inverter Pogwiritsa ntchito ukadaulo wowongolera wopanda mphamvu, rotor yamoto imatha kuyikika popanda kafukufuku. Ndi PWM controllable rectifying technology, inverter imatha kutulutsa zosalala za sine wave kuti ipititse patsogolo kuyendetsa bwino kwagalimoto. Inverter imayikidwa mwachindunji pa unit, kupulumutsa malo pansi kwa makasitomala. Kuphatikiza apo, mawaya onse olumikizirana amalumikizidwa mufakitale kuti apititse patsogolo kudalirika kwa unit.
	Low mamasukidwe akayendedwe vane diffuser Mapangidwe apadera a viscosity vane diffuser ndi airfoil guide vane amatha kutembenuza mpweya wothamanga kwambiri kukhala mpweya wothamanga kwambiri kuti athe kuchira. Pansi pakulemedwa pang'ono, kupatukana kwa vane kumachepetsa kutayika kwa m'mbuyo, kumapangitsa magwiridwe antchito pang'ono, ndikukulitsa magwiridwe antchito a unit.
Ukadaulo wapaintaneti wamagawo awiri Poyerekeza ndi makina a firiji agawo limodzi, kuponderezana kwa magawo awiri kumathandizira kuti ma circulation ayende bwino ndi 5% ~ 6%. Liwiro lozungulira la Compressor limatsitsidwa kuti kompresa ikhale yodalirika komanso yolimba.
	High-changu hermetic impeller Compressor impeller ndi ternary hermetic impeller, yomwe imagwira bwino ntchito komanso yodalirika kuposa chopondera chosavala. Imatengera mawonekedwe a airfoil 3-dimensional kuti ikhale yosinthika. Kupyolera mu kusanthula kwazinthu zomalizidwa, makina oyendera a 3-coordinate, kuyesa kwamphamvu, kuyesa mothamanga kwambiri komanso kuyesa kwenikweni pansi pa momwe amagwirira ntchito, zimatsimikiziridwa kuti chowongolera chikukwaniritsa zofunikira zamapangidwe ndipo chimatha kugwira ntchito mokhazikika. Impeller ndi shaft yoyambira imagwiritsa ntchito kulumikizana kopanda ma key, komwe kumatha kupewa kupsinjika pang'ono komanso kusinthasintha kwa rotor komwe kumachitika chifukwa cha kulumikizana kwakukulu, motero kumapangitsa kukhazikika kwa ntchito ya compressor.
Chotenthetsera chapamwamba kwambiri Kutentha kwapang'onopang'ono kumapangidwa potengera njira yotumizira kutentha. Iwo wokometsedwa kuchepetsa kuthamanga kuthamanga kutaya ndi mowa mphamvu. Sub-cooler ili ndi pansi pa condenser. Ndi zoletsa zingapo, kuziziritsa pang'ono kumatha kufika 5 ℃. Gulu lodzipatula lapakati limatenga chitoliro chopepuka chomwe chimakhala chokhuthala kuwirikiza kawiri ngati chitoliro cholumikizidwa ndi bolodi, chifukwa chake, chitoliro chamkuwa sichidzawonongeka chifukwa cha friji yothamanga kwambiri. Mapangidwe a 3-V grooved chubu amatengedwa kuti atsimikizire kusindikiza.
	MwaukadauloZida ulamuliro nsanja 32-bit CPU ndi purosesa ya digito ya DSP imagwiritsidwa ntchito. Kusonkhanitsidwa kwapamwamba kwa deta ndi mphamvu zogwiritsira ntchito deta zimatsimikizira nthawi yeniyeni ndi kulondola kwa kayendetsedwe ka kayendetsedwe kake. Pamodzi ndi chojambula chowoneka bwino cha LCD, wogwiritsa ntchito amatha kuzindikira kuwongolera kwamagalimoto ndikuwongolera pamanja pakuwongolera. Komanso utenga wanzeru Fuzzy-PID pawiri ulamuliro aligorivimu, amene Integrated ndi ukadaulo wanzeru, fuzziness luso ndi wamba PID kulamulira aligorivimu, kotero kuti dongosolo amatha kuyankha mofulumira liwiro ndi ntchito khola.
