Qhov zoo

• High degree ntawm efficiency nce mus txog 90%

• Integrated controller (kev tswj tsis tu ncua)

• Kev ua haujlwm ntxiv (kev tswj siab, airflow, ceev, kub, huab cua zoo, thiab lwm yam)

• Lub cev muaj zog me me rau tib theem ntawm kev ua haujlwm

• Tsawg zog siv

EC-kiv cua muaj txog li 30% ntau dua li AC-kiv cua

EC lub cev muaj zog efficiency nyob nruab nrab ntawm 80% thiab 90%. Txhawm rau muab qhov no rau hauv qhov kev xav, peb theem induction motors siab tshaj plaws yog 75%, thiab PSC (permanent split capacitor) motors muaj qhov ua tau zoo tshaj plaws ntawm 60% thiab 70%.

EC-kiv cua muaj lub neej ntev dua

EC motors 'kev ua haujlwm siab kuj txhais tau hais tias cov motors khiav" txias", thiab txo qis cov khoom siv hluav taws xob ntau. Txo cov cua sov ntawm cov evaporator lub cev muaj zog kuj feem ntau ua rau txo qis kev ua haujlwm ntawm qib compressor, uas tso cai rau kev txuag hluav taws xob ntxiv. Tsis tas li ntawd, kev khiav dej txias txhim kho lub neej ntawm cov khoom siv lub cev muaj zog xws li windings thiab bearings.

EC-kiv cua muaj kev ua haujlwm dav dua

EC motors kuj muaj ntau yam kev khiav hauj lwm ntau dua li ib txwm induction motors, uas txhais tau hais tias ib ECM lub cev muaj peev xwm hloov tau ib tug xov tooj ntawm induction motors. Hauv qhov no, tus naj npawb ntawm cov qauv xav tau los ntawm cov neeg siv khoom raug txo qis, uas txo qis thiab ua kom yooj yim cov khoom muag. Qhov no yog qhov laj thawj tseem ceeb vim li cas ECM cov kab khoom feem ntau suav nrog cov qauv qis dua li lawv qhov induction. cov neeg sib tw.
