Elinye lawona malungu aqhelekileyo anempazamo kwiinkqubo ze-HVAC zenqanaba elinye zii-capacitors ezisebenzayo, kangangokuba ngamanye amaxesha sibhekisa kumagcisa asezantsi “njengabatshintshi be-capacitor.”Nangona ii-capacitors zinokuba lula ukuxilonga kunye nokutshintsha, kukho izinto ezininzi ezinokuthi iingcali zingazazi.
I-capacitor sisixhobo esigcina iintlawulo ezihlukeneyo kwiipleyiti zetsimbi ezichasayo.Nangona ii-capacitors zinokusetyenziswa kwiisekethe ezonyusa i-voltage, aziwanyusi ngokwawo amandla ombane.Sisoloko sibona ukuba i-voltage kwi-capacitor iphezulu kune-voltage yomgca, kodwa oku kubangelwa amandla e-electromotive angasemva (i-back electromotive force) eyenziwa yi-motor, kungekhona i-capacitor.
Umchwephesha waqaphela ukuba icala lonikezelo lwamandla liqhagamshelwe kwi-C terminal okanye kwicala elichasene ne-valing winding.Iingcali ezininzi zicinga ukuba la mandla "ondla" kwi-terminal, anyuswe okanye adluliselwe, emva koko angene kwi-compressor okanye i-motor kwelinye icala.Nangona oku kunokuba sengqiqweni, ayisiyiyo indlela ii-capacitors ezisebenza ngayo.
I-HVAC esebenzayo ye-capacitor ngamashiti entsimbi amabini amade amade, agqunywe ngesithintelo esicekethekileyo seplastiki sokugquma, kunye nokuntywiliselwa kwi-oyile ukunceda ukukhupha ubushushu.Kanye njengeprayimari kunye neyesibini ye-transformer, ezi ziqwenga zimbini zetsimbi azikaze zidibane, kodwa ii-electron ziyaqokelelana kwaye zikhuphe kumjikelo ngamnye wokutshintshana kwangoku.Ngokomzekelo, ii-electron eziqokelelwe kwicala elithi "C" le-capacitor aziyi "kudlula" umqobo wokukhusela iplastiki ukuya kwicala elithi "Herm" okanye "Fan".La mandla mabini atsala kwaye akhulule i-capacitor kwicala elinye apho angena khona.
Kwi-PSC efakwe ngokufanelekileyo (i-Permanent Separate Capacitor) i-motor, ekuphela kwendlela yokuqalisa ukujika inokudlula nayiphi na yangoku kukugcina kunye nokukhupha i-capacitor.Okukhona iphezulu i-MFD ye-capacitor, kokukhona amandla agciniweyo makhulu kwaye kokukhona i-amperage yokuqalisa ukujikajika.Ukuba i-capacitor ayiphumelelanga ngokupheleleyo phantsi kwe-zero capacitance, iyafana nesiqalo sokuvula isiphaluka esivulekileyo.Ngexesha elizayo xa ufumanisa ukuba i-capacitor esebenzayo ayisebenzi kakuhle (akukho capacitor yokuqalisa), sebenzisa iipliers ukufunda i-amperage kwi-winging yokuqala kwaye ubone oko ndithethayo.
Yingakho i-capacitor enkulu inokonakalisa ngokukhawuleza i-compressor.Ngokwandisa umsinga ekujikeni kokuqala, icompressor iqala ukujikajika iya kuba sengozini yokusilela kwangoko.
Amagcisa amaninzi acinga ukuba kufuneka atshintshe i-370v capacitors kunye ne-370v capacitors.I-voltage elinganisiweyo ibonisa "akumele idlule" ixabiso elilinganisiweyo, oku kuthetha ukuba unokutshintsha i-370v nge-440v, kodwa awukwazi ukuthatha indawo ye-440v nge-370v.Oku kungaqondani kuqhelekile kangangokuba abaninzi abavelisi be-capacitor baqala ukunyathela i-440v capacitors nge-370 / 440v nje ukuphelisa ukudideka.
Kufuneka nje wenze umlinganiselo wangoku (i-amperes) we-motor iqala ukujika-jika equkuqela ukusuka kwi-capacitor kwaye uyiphindaphinde ngama-2652 (3183 kumandla angama-60hz, kunye namandla angama-50hz), emva koko wahlule elo nani ngombane owulinganiseleyo kwi-capacitor.
