Kimwe mu bice bikunze kwibeshya kuri sisitemu ya HVAC icyiciro kimwe ni capacator ikora, kuburyo kuburyo rimwe na rimwe tuvuga abatekinisiye bato nk "abahindura ubushobozi."Nubwo capacator zishobora kuba byoroshye gusuzuma no gusimbuza, hari ibintu byinshi abatekinisiye bashobora kuba batazi.
Ubushobozi ni igikoresho kibika amafaranga atandukanye ku byuma birwanya icyuma.Nubwo ubushobozi bwa capacitori bushobora gukoreshwa mumuzunguruko wongera imbaraga za voltage, ntabwo mubyukuri byongera voltage wenyine.Dukunze kubona ko voltage hejuru ya capacitori iruta umurongo wumurongo wa voltage, ariko ibi biterwa nimbaraga zinyuma zamashanyarazi (imbaraga za electromotive inyuma) zakozwe na moteri, ntabwo ari capacitor.
Umutekinisiye yabonye ko uruhande rwamashanyarazi ruhujwe na C ya C cyangwa uruhande rutandukanye nurujya n'uruza.Abatekinisiye benshi batekereza ko izo mbaraga "zigaburira" muri terminal, zikongerwamo imbaraga cyangwa zikimurwa, hanyuma zikinjira muri compressor cyangwa moteri ikanyura hakurya.Nubwo ibi bishobora kumvikana, ntabwo mubyukuri uburyo capacator zikora.
Ubusanzwe ubushobozi bwa HVAC bukora ni impapuro ebyiri ndende gusa zoroshye, zashyizwe hamwe na bariyeri yoroheje cyane, kandi zishizwe mumavuta kugirango zifashe gukwirakwiza ubushyuhe.Nka primaire na secondaire ya transformateur, ibi bice byombi byicyuma ntabwo byigeze bihura mubyukuri, ariko electron ziregeranya kandi zisohora hamwe na buri cyiciro cyumuzunguruko.Kurugero, electron zegeranijwe kuruhande rwa "C" za capacitor ntizigera "zinyura" inzitizi ya plastike ikingira "Herm" cyangwa "Umufana".Izi mbaraga zombi zikurura gusa no kurekura capacitor kuruhande rumwe aho zinjiye.
Kuri moteri ikozwe neza ya PSC (Permanent Separate Capacitor), inzira yonyine yo gutangira guhinduranya ishobora kunyura icyaricyo cyose nukubika no gusohora capacitor.Iyo MFD iri hejuru ya capacitor, niko imbaraga zabitswe ninshi hamwe na amperage yo gutangira kuzunguruka.Niba capacitor yananiwe rwose munsi ya zeru ubushobozi, ni kimwe no gutangira kuzunguruka gufungura.Ubutaha uzasanga capacitor ikora idakora neza (nta capacitori itangira), koresha pliers kugirango usome amperage kumurongo utangiye hanyuma urebe icyo nshaka kuvuga.
Niyo mpanvu ubushobozi bunini bushobora kwangiza compressor.Mugukomeza ibyagezweho mugitangira kizunguruka, compressor itangira guhindagurika bizakunda kunanirwa hakiri kare.
Abatekinisiye benshi bibwira ko bagomba gusimbuza 370v ubushobozi bwa 370v.Umuvuduko wapimwe werekana "ntugomba kurenza" agaciro kagenwe, bivuze ko ushobora gusimbuza 370v na 440v, ariko ntushobora gusimbuza 440v na 370v.Uku kutumvikana kurasanzwe kuburyo benshi mubakora capacitor batangiye gushyira kashe ya 440v hamwe na 370 / 440v kugirango bakureho urujijo.
Ukeneye gupima gusa (amperes) ya moteri itangira guhindagurika ituruka kuri capacitor hanyuma ukayigwiza kuri 2652 (3183 kuri 60hz power, na 50hz power), hanyuma ugabanye iyo mibare na voltage wapimye kuri capacitor.
