Chimwe chezvinhu zvinonyanya kukanganisa pachikamu chimwe chete cheHVAC masisitimu anoshanda capacitor, zvekuti dzimwe nguva tinodaidza majunior tekinoroji se "capacitor vanochinja."Kunyangwe ma capacitor angave ari nyore kuongorora uye kutsiva, pane zvinhu zvakawanda izvo matekinoroji angave asingazive.
A capacitor chishandiso chinochengeta machaji akasiyana pane anopikisa mahwendefa esimbi.Kunyangwe ma capacitor achigona kushandiswa mumaseketi anowedzera voltage, iwo haanyanyi kuwedzera voltage ega.Tinowanzoona kuti voltage mhiri capacitor yakakwirira kupfuura mutsetse voltage, asi izvi imhaka yeshure electromotive simba (kumashure electromotive simba) inogadzirwa nemotokari, kwete capacitor.
Nyanzvi yakaona kuti divi remagetsi rakabatana neC terminal kana divi rakatarisana nekumhanya mhepo.Vanamazvikokota vazhinji vanofungidzira kuti simba iri "rinodyisa" mukati meiyo terminal, rinokwidziridzwa kana kutamiswa, rozopinda mune compressor kana mota nerumwe rutivi.Kunyangwe izvi zvingave zvine musoro, hazvisi izvo chaizvo mashandiro anoita capacitors.
Yakajairika HVAC inoshanda capacitor angori maviri marefu matete simbi mashiti, akavharidzirwa neakanyanya kutetepa epurasitiki insulation barriers, uye akanyudzwa mumafuta kubatsira kubvisa kupisa.Kungofanana nepuraimari nesekondari yetransformer, zvidimbu zviviri izvi zvesimbi hazvina kumbobvira zvasangana, asi maerekitironi anounganidza nekubuda nekutenderera kwega kwega kwekuchinjana ikozvino.Semuenzaniso, maerekitironi akaungana kudivi re "C" re capacitor "haambofa akapfuudza" chipingamupinyi chepurasitiki kudivi re "Herm" kana "Fan".Aya mauto maviri anongokwezva nekusunungura capacitor kudivi rimwe chete ravanopinda.
Pane yakanyatso tambo waya PSC (Permanent Separate Capacitor) mota, iyo chete nzira yekutanga mhepo inogona kupfuura chero yazvino ndeye kuchengeta uye kuburitsa capacitor.Iyo yakakwirira iyo MFD ye capacitor, iyo yakakura iyo yakachengetwa simba uye yakakura amperage yekutanga mhepo.Kana iyo capacitor ikakundikana zvachose pasi pe zero capacitance, zvakafanana nekutanga mhepo yakavhurika redunhu.Nguva inotevera paunoona kuti iyo inomhanya capacitor isiri kushanda (hapana yekutanga capacitor), shandisa pliers kuti uverenge amperage pane yekutanga mhepo uye ona zvandiri kureva.
Ichi ndicho chikonzero iyo oversized capacitor inogona kukurumidza kukuvadza compressor.Nekuwedzera ikozvino pane yekutanga mhepo, iyo compressor inotanga mhepo inozonyanya kukonzeresa kutadza kwekutanga.
Nyanzvi dzakawanda dzinofunga kuti dzinofanira kutsiva 370v capacitor ne 370v capacitors.Iyo yakatemerwa voltage inoratidza "haifanire kudarika" kukosha kwakayerwa, zvinoreva kuti unogona kutsiva 370v ne440v, asi haugone kutsiva 440v ne370v.Kusanzwisisana uku kwakajairika zvekuti vazhinji vanogadzira capacitor vakatanga kudzvanya 440v capacitor ne 370/440v kungobvisa kuvhiringidzika.
Iwe unongoda kuyera yazvino (amperes) yemota inotanga kutenderera ichiyerera ichibva kune capacitor uye woiwedzera ne2652 (3183 pa60hz simba, uye pa50hz simba), wogovanisa iyo nhamba nevoltage yawakayera mhiri kwecapacitor.
