Mid ka mid ah qaybaha ugu caansan ee cilladaysan ee nidaamyada HVAC-hal-waji ah waa kapacitors-ka shaqeeya, si aan mararka qaarkood u tixraacno farsamayaqaannada da'da yar sida "beddelayaasha awoodda."Inkastoo capacitors laga yaabo inay fududahay in la ogaado oo la beddelo, waxaa jira waxyaabo badan oo laga yaabo in farsamayaqaanadu aysan garanayn.
Capacitor waa aalad ku kaydisa kharashyada kala duwan ee taarikada birta ah ee iska soo horjeeda.Inkasta oo capacitors loo isticmaali karo wareegyada kor u qaada tamarta, dhab ahaantii ma kordhiyaan korantada naftooda.Waxaan inta badan aragnaa in korantada ku jirta capacitor-ka uu ka sarreeyo danab xariiqda, laakiin tani waxaa sabab u ah xoogga dambe ee elektromotive (xoogga dambe ee electromotive) ee uu dhaliyo mootada, ma aha capacitor.
Farsamoyaqaanku waxa uu ogaaday in dhinaca korantadu ay ku xidhan tahay Terminalka C ama dhinaca ka soo horjeeda dabaysha ordaya.Farsamayaqaanno badan ayaa u malaynaya in tamartani "quudinayso" terminalka, la kordhiyo ama la wareejiyo, ka dibna ay gasho kombaresarka ama mashiinka dhinaca kale.Inkasta oo ay tani macno samayn karto, ma aha run ahaantii sida capacitors u shaqeeyaan.
Qalabka HVAC ee caadiga ah waa laba go'yaal dhuuban oo dheer oo bir ah, oo lagu dahaadhay xannibaad caag ah oo aad u khafiif ah, oo lagu rusheeyey saliid si ay uga caawiso daadinta kulaylka.Sida aasaasiga iyo sare ee transformer-ka, labadan xabbadood ee birta ah weligood lama xidhiidhin, laakiin elektaroonnada ayaa urura oo soo daaya wareeg kasta oo beddelka hadda ah.Tusaale ahaan, elektaroonnada lagu soo ururiyey dhinaca "C" ee capacitor-ka waligood kama " gudbi doonaan" xannibaadda caagga ah ee dhinaca "Herm" ama "Fan".Labadan ciidan ayaa si fudud u soo jiidanaya oo sii daaya capacitor-ka isla dhinaca ay ka soo galayaan.
Matoorka PSC (Kapacitor Joogta ah ee Joogtada ah), sida kaliya ee dabaylaha bilawga ahi ugu gudbi karo wax kasta oo hadda jira waa in la kaydiyo oo la soo saaro capacitor-ka.Marka uu sareeyo MFD ee kombuyuutarku, way sii weynaataa tamarta kaydsan oo way sii weynaataa amperage-ka dabaysha bilawga ah.Haddii capacitor-ku uu gabi ahaanba ku guuldareysto in uu ka hooseeyo awoodda eber, waxa ay la mid tahay bilawga wareegga furan ee dabaysha.Marka xigta waxaad ogaataa in capacitor-ka ordaya uu cilladaysan yahay (ma jiro capacitor bilow ah), isticmaal qalabyada si aad u akhrido amperage-ka dabaylaha bilawga ah oo arag waxa aan ula jeedo.
Tani waa sababta capacitor-ka weyni uu si dhakhso ah u dhaawici karo kombarada.Marka la kordhiyo dabaylaha bilawga ah ee hadda socda, kombaresarada bilawga dabaysha waxay aad ugu nugulaan doontaa fashilka hore.
Farsamayaqaanno badan ayaa qaba inay qasab ku tahay inay 370v capacitors ku beddelaan 370v capacitors.Korantada la qiimeeyay waxay muujinaysaa "waa inaanu ka badnayn" qiimaha la qiimeeyay, taas oo macnaheedu yahay inaad ku bedeli karto 370v 440v, laakiin ma bedeli kartid 440v 370v.Isfaham la'aantan ayaa ah mid caadi ah in shirkado badan oo soo saara capacitor ay bilaabeen inay ku shaabadeeyaan 440v capacitors 370/440v kaliya si meesha looga saaro jahawareerka.
Kaliya waxaad u baahan tahay inaad cabbirto (amperes) ee matoorka bilawga dabaysha ka soo qulqulaya capacitor oo ku dhufo 2652 (3183 at 60hz power, iyo 50hz power), ka dibna u qaybi lambarkaas korantada aad ku cabirtay guud ahaan capacitor .
