E 'ngoe ea likarolo tse fosahetseng tse tloaelehileng ho sistimi e le 'ngoe ea HVAC ke li-capacitor tse sebetsang, hoo ka linako tse ling re bitsang litsebi tse tlase e le "li-capacitor chenger".Le hoja li-capacitor li ka 'na tsa e-ba bonolo ho li hlahloba le ho li fetola, ho na le lintho tse ngata tseo litsebi li ka' nang tsa se ke tsa li tseba.
Capacitor ke sesebelisoa se bolokang litefiso tse fapaneng ho lipoleiti tsa tšepe tse hanyetsanang.Le hoja li-capacitor li ka sebelisoa lipotolohong tse matlafatsang motlakase, ha e le hantle li eketsa motlakase ka botsona.Re atisa ho bona hore motlakase ho pholletsa le capacitor o phahame ho feta matla a motlakase, empa sena se bakoa ke matla a morao a motlakase (morao electromotive force) a hlahisoang ke motlakase, eseng capacitor.
Setsebi se hlokometse hore lehlakore la phepelo ea motlakase le hoketsoe ho terminal ea C kapa lehlakoreng le fapaneng le matsoelintsoeke a tsamaeang.Litsebi tse ngata li nahana hore matla ana a "fepa" ka har'a terminal, a matlafatsoa kapa a fetisoa, ebe a kena ka har'a compressor kapa motor ka lehlakoreng le leng.Leha sena se ka utloahala, ha se hantle hore na li-capacitor li sebetsa joang.
HVAC e tloaelehileng ea ho sebetsa capacitor ke lishiti tse peli feela tse telele tsa tšepe tse tšesaane, tse kentsoeng ka sekoaelo se tšesaane haholo sa polasetiki, 'me se qoelisoa ka har'a oli ho thusa ho tlosa mocheso.Feela joalo ka ea mantlha le ea bobeli ea transformer, likotoana tsena tse peli tsa tšepe ha li e-so ka li kopana, empa lielektrone lia bokellana le ho tsoa ka potoloho e 'ngoe le e' ngoe ea hona joale.Ka mohlala, li-electrone tse bokaneng ka lehlakoreng la "C" la capacitor li ke ke tsa "fetisa" mokoallo oa polasetiki ho lehlakoreng la "Herm" kapa "Fan".Matla ana a mabeli a hohela le ho lokolla capacitor ka lehlakoreng le le leng moo a kenang teng.
Ho enjene ea PSC e nang le lithapo tse nepahetseng (Permanent Separate Capacitor), tsela e le 'ngoe feela eo moea oa ho qala o ka fetang hona joale ke ho boloka le ho lahla capacitor.Ha MFD e phahame ea capacitor, matla a bolokiloeng a maholo le ho feta amperage ea matsoeli a qalang.Haeba capacitor e hlōleha ka ho feletseng tlas'a zero capacitance, ho tšoana le ho qala potoloho e bulehileng ea matsoelintsoeke.Nakong e tlang ha u fumana hore capacitor e mathang ha e sebetse hantle (ha ho na capacitor ea ho qala), sebelisa pliers ho bala amperage ha ho qala moea 'me u bone seo ke se bolelang.
Ke kahoo capacitor e kholo e ka senyang compressor kapele.Ka ho eketsa matla a hona joale ha ho qala matsoelintsoeke, compressor e qala matsoelintsoeke e tla ba le monyetla oa ho hloleha kapele.
Litsebi tse ngata li nahana hore li tlameha ho nkela li-capacitor tsa 370v sebaka ka li-capacitor tsa 370v.Matla a lekantsoeng a bontša "ha aa lokela ho feta" boleng bo lekantsoeng, ho bolelang hore o ka nkela 370v sebaka ka 440v, empa u ke ke ua nkela 440v sebaka ka 370v.Ho se utloisisane hona ho tloaelehile hoo bahlahisi ba bangata ba li-capacitor ba ileng ba qala ho hatisa li-capacitor tsa 440v ka 370 / 440v feela ho felisa pherekano.
U hloka feela ho lekanya hona joale (amperes) ea ho qala ha motlakase ho phalla ho tloha ho capacitor le ho e atisa ka 2652 (3183 ho 60hz matla, le ka matla a 50hz), ebe u arola palo eo ka motlakase oo u o lekantseng ho pholletsa le capacitor .
