IIsixhobo soqhagamshelwano lwe-AClicandelo elibalulekileyo kwinkqubo yomoya opholileyo kwaye lidlala indima ebalulekileyo ekulawuleni ukuhamba kombane kwi-compressor nakwi-condenser. Yi-relay evula kwaye icime amandla e-AC. Le contactor yenzelwe ukuphatha ii-voltages eziphezulu kunye nemisinga, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo yokusebenza kwenkqubo yomoya opholileyo iyonke.
Umsebenzi ophambili we-AC contactor kukusebenza njengeswitshi yeeyunithi ze-compressor kunye ne-condenser kwinkqubo yomoya opholileyo. Xa i-thermostat inika imiqondiso yokuba kufuneka ukupholisa, i-contactor ifumana isignali yombane yokuvala isekethe kwaye ivumele umbane wombane ukuba ugeleze kwi-compressor kunye ne-condenser. Eli nyathelo liqala inkqubo yokupholisa ngokusebenzisa izixhobo ezinoxanduva lokususa ubushushu emoyeni wangaphakathi.
Iicontactor ze-AC zihlala zenzelwe ukusingatha imithwalo yombane ephezulu enxulumene neenkqubo zomoya-moya. Zenziwe ngezinto ezihlala ixesha elide ezinokumelana nombane ophezulu kunye nomsinga ofunekayo ukunika amandla i-compressor kunye ne-condenser. Oku kuqinisekisa ukuba i-contactor ilawula ngokuthembekileyo nangokukhuselekileyo ukuhamba kombane kwiyunithi ye-AC, nokuba isetyenziswa kakhulu.
Ukongeza ekulawuleni amandla kwi-compressor nakwi-condenser, i-AC contactor ikwabonelela ngomgangatho wokhuseleko kwinkqubo yomoya opholileyo. Zixhotyiswe ngezinto ezifana nokukhusela ukugqithisa kunye nokukhusela i-short-circuit ukukhusela izinto zombane ekonakalisweni yi-overcurrent okanye i-voltage spikes. Oku kunceda ukwandisa ubomi benkqubo yakho yomoya opholileyo kwaye kuthintele iingozi ezinokubakho ngenxa yeziphene zombane.
Iicontactor ze-AC ziyafumaneka ngeendlela ezahlukeneyo zokulungiselela iintlobo ezahlukeneyo kunye nobukhulu beeyunithi zomoya opholileyo. Ziza ngoyilo lwe-unipolar, bipolar, kunye ne-three-pole, kwaye ulwakhiwo ngalunye luhambelana neemfuno ezithile ze-voltage kunye ne-current. Ukongeza, iicontactors zinokuba ne-coil voltage ratings ezahlukeneyo ukuze zihambelane neenkcukacha zombane zenkqubo yomoya opholileyo.
Ukugcinwa rhoqo kunye nokuhlolwa kwe-contactor ye-AC kubalulekile ukuqinisekisa ukusebenza kwayo ngokufanelekileyo. Ekuhambeni kwexesha, izihlanganisi ezikwi-contactor zinokuguga ngenxa yokuxinana okwenzeka ngexesha lokutshintsha. Oku kunokubangela ukwanda kokuxhathisa kunye nolawulo olungasebenzi kakuhle lombane. Ke ngoko, kuyimfuneko ukujonga nokucoca izihlanganisi rhoqo ukuze kugcinwe ukusebenza kakuhle.
Ngamafutshane, i-AC contactor yinxalenye ebalulekileyo ekusebenzeni kwenkqubo yomoya opholileyo. Isebenza njengesitshintshi esithembekileyo sokulawula amandla kwi-compressor nakwi-condenser ngelixa ikwabonelela ngokhuseleko kwiimpazamo zombane. Ngokuqonda ukubaluleka kwe-AC contactor nokuqinisekisa ukuba igcinwe kakuhle, abanini bezindlu kunye neengcali ze-HVAC banokunceda ukuqinisekisa ukusebenza kakuhle nangokukhuselekileyo kweenkqubo zabo zomoya opholileyo.
