Yakakwira-kumhanya inogara magineti synchronous inverter mota

Yekutanga pasirese yepamusoro-simba uye yakakwirira-kumhanya PMSM inoshandiswa kune iyi centrifugal chiller.Simba rayo rakakwirira kudarika 400 kW uye kumhanya kwayo kutenderera kuri pamusoro pe18000 rpm.Kushanda kwemota kuri pamusoro pe96% uye 97.5% kusvika pakakwirira, yakakwira kupfuura yenyika giredhi 1 standard pakuita kwemota.Iyo compact uye lightweight.A 400kW high-speed PMSM inorema zvakafanana ne75kW AC induction motor.Nekutora spiral refrigerant spraying kutonhora tekinoroji kutonhora pasi stator uye rotor, tembiricha yemota inogona kudzorwa kunosvika 40 ℃, kuve nechokwadi chekushanda kwakanaka.

High-speed injini yakananga-inotyairwa maviri-nhanho impellerYuniti inotora yakakwira-kumhanya mota yakananga-inotyairwa maviri-nhanho impeller.Speed-up magiya uye 2 radial mabearings akadzimwa, izvo zvichavandudza kushanda zvakanaka uye kuderedza kurasikirwa kwemechini ne70%.Iine yakananga dhiraivha uye yakapusa chimiro, compressor inoshanda yakavimbika mudiki saizi.Vhoriyamu uye huremu hwecompressor ingori 40% yehumwe huwandu hwakajairwa compressor.Pasina iyo yakakwira-frequency ruzha rwekumhanyisa-kumusoro magiya, kushanda kwecompressor kwakadzikira zvakanyanya.Ndiyo 8dBA yakaderera pane yakajairika unit.
	All-condition "wideband" pneumatic dhizaini Impeller uye diffuser inogadziridzwa kuti ione yakakwirira-inoshanda ye compressor pasi pe25-100% mutoro.Kuenzaniswa neyakajairwa dhizaini yakavakirwa pakushanda kwakazara kwemutoro, dhizaini iyi inogona kuderedza kushanda kwecompressor.Conventional inverter centrifugal chiller inoziva kutonga kwesimba nekuchinjika kumhanya kwecompressor uye inoshanduka yekuvhura angle yegidhi vane iyo inotanga kudzikira pasi pe50 ~ 60% mutoro.Nekudaro, Gree CVE yakatevedzana centrifugal chiller inogona kushandura zvakananga kumhanya kwecompressor pasi pe25 ~ 100% mutoro kudzikisa throttling kurasikirwa kwegidhi vane uye kunatsiridza mashandiro ekushanda pasi pemamiriro ese.
Yakaiswa sine-wave inverter Nekutora chinzvimbo-sensorless control tekinoroji, mota rotor inogona kuiswa pasina probe.Iine PWM inodzoreka kugadzirisa tekinoroji, inverter inogona kuburitsa yakatsetseka sine wave kuvandudza mota inoshanda.Inverter yakaiswa zvakananga payuniti, ichichengetedza pasi nzvimbo yevatengi.Pamusoro pezvo, waya dzese dzekutaurirana dzakabatanidzwa mufekitori kuti dzivandudze kuvimbika kweyuniti.
	Low viscosity vane diffuser Yakasarudzika yakaderera viscosity vane diffuser dhizaini uye airfoil inotungamira vane inogona kushandura yakakwira-kumhanya gasi kuita yakakwira static pressure gasi zvinobudirira kuona kudzoreredza kupora.Pasi pemutoro usina kukwana, vane diversion inoderedza kurasikirwa kwekudzokera shure, inovandudza chikamu chemutoro wekuita, uye inowedzera kushandiswa kweyuniti.
Maviri-nhanho compression tekinoroji Kuenzaniswa ne-single-stage refrigeration system, maviri-nhanho compression inovandudza kutenderera kwakanaka ne5%～6%.Compressor rotational speed inodzikiswa kuitira kuti compressor ive yakavimbika uye yakasimba.
	High-efficiency hermetic impeller Compressor impeller ndeye ternary hermetic impeller, iyo inoshanda zvakanyanya uye yakavimbika pane isina kuvharwa impeller.Iyo inotora airfoil 3-dimensional chimiro kuitira kuti iwedzere kuchinjika.Kuburikidza neinogumira chekuongorora chinhu, 3-inoronga yekuongorora muchina, ine simba chiyero bvunzo, yakakwira-kumhanya bvunzo uye chaiyo bvunzo pasi pemamiriro chaiwo ekushanda, inove nechokwadi chekuti impeller inosangana nezvinodiwa dhizaini uye inokwanisa kushanda yakagadzikana.Impeller uye basic shaft inotora keyless yekubatanidza, iyo inogona kudzivirira chikamu chekushushikana kusungirirwa uye rotor's additive off-balance iyo inokonzerwa nekiyi yekubatanidza, nekudaro inovandudza kushanda kwe compressor.
High-effective heat exchanger Heat exchange surface inogadzirwa zvichienderana nekupisa-kutamisa michina.Iyo yakagadziridzwa kuderedza kuyerera kwekumanikidzwa kurasikirwa uye kushandiswa kwesimba.Sub-cooler yakashongedzerwa pazasi pecondenser.Iine akawanda ekuyerera anodzivirira, sub-kutonhora dhigirii inogona kusvika ku5 ℃.Yepakati yekuzviparadzanisa nevamwe inotora pombi yakareruka yakapetwa kaviri sepombi yakarukwa kuti ibatanidzwe nebhodhi rinotsigira, saka, pombi yemhangura haizokanganiswe pasi pekukanganisa kwefiriji yekumhanya.3-V grooved chubhu dhizaini dhizaini inogamuchirwa kuti ive nechokwadi chekuisa chisimbiso.
	Yepamusoro kudzora chikuva High-performance 32-bit CPU uye DSP digital signal processor inoshandiswa.Iyo yakakwira yekuunganidza data kurongeka uye data yekugadzirisa simba inovimbisa iyo chaiyo-nguva chimiro uye kurongeka kwekutonga system.Pamwe chete neyakajeka LCD yekubata sikirini, mushandisi anogona kuona zviri nyore kudzora otomatiki uye manyorero ekudzora mukugadzirisa.Iyo zvakare inotora yakangwara Fuzzy-PID komboni control algorithm, iyo inosanganiswa nehungwaru tekinoroji, fuzziness tekinoroji uye yakajairwa PID control algorithm, kuitira kuti sisitimu inokwanisa kukurumidza kupindura nekukurumidza uye kuita kwakagadzikana.
