Chimodzi mwazinthu zolakwika kwambiri pamakina amtundu umodzi wa HVAC ndi ma capacitor ogwiritsira ntchito, kotero kuti nthawi zina timatchula akatswiri achichepere ngati "osintha ma capacitor."Ngakhale ma capacitor angakhale osavuta kuwazindikira ndikuwongolera, pali zinthu zambiri zomwe akatswiri sangadziwe.
Capacitor ndi chipangizo chomwe chimasungira ndalama zosiyana pazitsulo zotsutsana.Ngakhale ma capacitor atha kugwiritsidwa ntchito m'mabwalo omwe amawonjezera ma voliyumu, samawonjezera voteji okha.Nthawi zambiri timawona kuti voteji kudutsa capacitor ndi apamwamba kuposa voteji mzere, koma chifukwa cha kumbuyo electromotive mphamvu (kumbuyo electromotive mphamvu) kwaiye ndi galimoto, osati capacitor.
Katswiriyu adawona kuti mbali yamagetsi yamagetsi imalumikizidwa ndi C terminal kapena mbali yoyang'anizana ndi mafunde othamanga.Akatswiri ambiri amaganiza kuti mphamvu izi "zimadyetsa" mu terminal, zimalimbikitsidwa kapena kusamutsidwa, ndiyeno zimalowa mu kompresa kapena mota kudutsa mbali inayo.Ngakhale izi zitha kukhala zomveka, sizomwe ma capacitors amagwirira ntchito.
Makina ogwiritsira ntchito a HVAC amangokhala zitsulo ziwiri zazitali zopyapyala, zotchingidwa ndi chotchinga chotchinga cha pulasitiki chopyapyala, komanso kumizidwa m'mafuta kuti athetse kutentha.Monga ngati thiransifoma ya pulayimale ndi yachiwiri, zidutswa ziwiri zazitsulozi sizinagwirizanepo, koma ma elekitironi amaunjikana ndikutuluka ndi kuzungulira kwa ma alternating current.Mwachitsanzo, ma elekitironi osonkhanitsidwa ku mbali ya "C" ya capacitor "sadzadutsa" chotchinga chotchinga cha pulasitiki ku mbali ya "Herm" kapena "Fan".Mphamvu ziwirizi zimangokopa ndikumasula capacitor kumbali imodzi yomwe amalowa.
Pa injini ya PSC (Permanent Separate Capacitor) yolumikizidwa bwino, njira yokhayo yomwe mafunde amatha kudutsa pakali pano ndikusunga ndikutulutsa capacitor.Kukwera kwa MFD ya capacitor, kumapangitsanso mphamvu zosungidwa komanso kuchuluka kwa mafunde oyambira.Ngati capacitor ikulephera kwathunthu pansi pa zero capacitance, ndizofanana ndi chiyambi chotsegulira dera lotseguka.Nthawi ina mukapeza kuti capacitor ikuyenda bwino (palibe capacitor yoyambira), gwiritsani ntchito pliers kuti muwerenge amperage pamayendedwe oyambira ndikuwona zomwe ndikutanthauza.
Ichi ndichifukwa chake capacitor yochulukirapo imatha kuwononga kompresa mwachangu.Powonjezera mphamvu yamagetsi pamayambiriro oyambira, kompresa imayamba kupendekera kudzakhala kosavuta kulephera koyambirira.
Akatswiri ambiri amaganiza kuti akuyenera kusintha ma capacitor a 370v ndi ma 370v capacitors.Magetsi ovotera akuwonetsa kuti "sayenera kupitilira" mtengo wake, zomwe zikutanthauza kuti mutha kusintha 370v ndi 440v, koma simungasinthe 440v ndi 370v.Kusamvetsetsana kumeneku ndikofala kwambiri kotero kuti opanga ma capacitor ambiri adayamba kupondaponda ma 440v capacitors ndi 370/440v kuti athetse chisokonezo.
Mukungoyenera kuyeza mafunde apano (ma amperes) a momwe injini imayambira kuyenda kuchokera pa capacitor ndikuchulukitsa ndi 2652 (3183 pa 60hz mphamvu, ndi mphamvu ya 50hz), kenako gawani nambalayo ndi voteji yomwe munayeza pa capacitor .
Mukufuna kudziwa zambiri zamakampani a HVAC ndi zambiri?Lowani nawo NKHANI pa Facebook, Twitter ndi LinkedIn tsopano!

Zomwe zathandizidwa ndi gawo lolipidwa lapadera pomwe makampani opanga makampani amapereka zinthu zapamwamba kwambiri, zomwe sizili zamalonda kuzungulira mitu yomwe ili yosangalatsa kwa omvera nkhani za ACHR.Zonse zomwe zimathandizidwa zimaperekedwa ndi makampani otsatsa.Kodi mukufuna kutenga nawo mbali pagawo lathu lothandizira?Chonde funsani woyimira kwanuko.
