Kodi Damper Motor ya Firiji Yozizidwa ndi Air Imagwira Ntchito Motani?

Njira zambiri zamafiriji masiku ano zasiya kuziziritsa mwachindunji ndikutengera njira zoziziritsira mpweya, ndipo mafiriji oziziritsidwa ndi mpweya alibe gawo lalikulu ladamper yamagetsi. Thedamper yamagetsiimapangidwa makamaka ndi stepper motor, transmission mechanism, mbale ya khomo ndi chimango cha khomo. Monga chinthu chachikulu chowongolera kuchuluka kwa mpweya, chowongolera chowongolera mufiriji chimayatsidwa, ndipo chotchinga pamakona amakona anayi chimayendetsedwa ndi njira yochepetsera magiya, ndipo kutsegulidwa kwa baffle kumayendetsedwa ndi kusinthasintha kwabwino ndi koyipa kwa stepper motor ndi kuchuluka kwa ma pulse masitepe. Pamene adamper yamagetsindi lotseguka, mpweya ozizira amalowa m'chipinda cholamulidwa mwa njira mpweya kudzeradamper yamagetsidzenje, ndipo mpweya wozizira m'chipinda chilichonse umapanga convection kudzera munjira ya mpweya kuti mukwaniritse kuzizira. Thedamper yamagetsichatsekedwa ndipo kutuluka kwa mpweya kumadulidwa. Kuti muwongolere kutuluka kwa mpweya wozizira m'chipinda chozizira cha firiji, iyi ndi mfundo yogwirira ntchito yamoto wa firiji, ndi gawo lanji lomwe injiniyo imachita mufiriji magetsi damper?

Ntchito yayikulu ndi kuchuluka kwa mpweya wosinthika, firijidamper yamagetsiamagwiritsa ntchito galimoto stepper, makwerero ake ngodya ndi masitepe 7.5, mwa kamangidwe koyenera wa kuchepetsa zida kufala chiŵerengero, sitepe iliyonse ya stepper galimoto akhoza kupanga baffle kugwedezeka 0.5, ndiko kuti, baffle kuchokera chatsekedwa kutsegula pazipita 90. The kugwedezeka ngodya kumafuna stepper galimoto 1800 masitepe, ndi zimachitika pang'onopang'ono nambala zosakwana 1800 zosakwana 1800 kugwedezeka. Madigiri 90, kotero kuti baffle amatha kusintha kuchuluka kwa mpweya wopanda kanthu.
