Iyunithi yekhoyili yefeni ishunqulelwe njengekhoyili yefeni.Ngenye yezixhobo zokugqibela zenkqubo ye-air conditioning eyenziwe ngabalandeli abancinci, iimoto kunye neekhoyili (abatshintshi bobushushu bomoya).Xa amanzi abandayo okanye amanzi ashushu ehamba ngetyhubhu yekhoyili, itshintshisa ubushushu kunye nomoya ngaphandle kombhobho, ukuze umoya upholile, uhlanjululwe okanye ushushu ulungelelanise iiparamitha zomoya wangaphakathi.Sisixhobo esiqhele ukusetyenziswa kwitheminali ukupholisa nokufudumeza.
Iiyunithi zekhoyili yefeni zinokwahlulwa ngokweeyunithi ezithe nkqo zekhoyili yefeni, iiyunithi zekhoyili yefeni ethe tyaba, iiyunithi zekhoyili yefeni efakwe eludongeni, iiyunithi zekhoyili yefeni yekhasethi, njl.Phakathi kwazo, iiyunithi zekhoyili yeefeni ezithe nkqo zahlulwe zaba ziiyunithi ezithe nkqo zekhoyili yeefeni kunye neeyunithi zekhoyili yeekhoyili.Iikhoyili zefeni ezisezantsi;ngokwendlela yokufakela, inokwahlulwa ibe ziikhoyili zefeni ezixhonywe phezulu kunye neekhoyili ezifihliweyo;ngokwendlela yokuthatha amanzi, inokwahlulwa ibe ziikhoyili zefeni ezisekhohlo kunye neekhoyili zasekunene.Iiyunithi ze-fan-coil ezifakwe eludongeni zizo zonke iiyunithi ezibekwe phezu komhlaba, kunye nesakhiwo esihlangeneyo kunye nenkangeleko enhle, exhonywe ngokuthe ngqo phezu kodonga.Uhlobo lwekhasethi (i-ceiling embedded unit), i-air inlet kunye ne-outlet enhle ngakumbi ibonakaliswe phantsi kwesilingi, kwaye i-fan, i-motor kunye ne-coil zibekwe kwisilingi.Yiyunithi evezwe kancinci.Iyunithi ephakanyiswe phezulu inegobolondo elihle, kunye ne-air inlet kunye ne-outlet, evezwe kwaye ifakwe kwigumbi.Igobolondo leyunithi efihliweyo ngokuqhelekileyo yenziwe ngentsimbi ye-galvanized.Iiyunithi ze-fan-coil zahlulahlulwe ngamacandelo amabini ngokuhambelana noxinzelelo lwangaphandle lwe-static: uxinzelelo oluphantsi lwe-static kunye noxinzelelo oluphezulu lwe-static.Uxinzelelo lwe-static lokuphuma lweyunithi yoxinzelelo oluphantsi lwe-static kumthamo womoya olinganisiweyo ngu-0 okanye i-12Pa, kwiyunithi ene-tuyere kunye ne-filter, i-outlet static pressure yi-0;kwiyunithi ngaphandle kwe-tuyere kunye nesihluzo, i-outlet yoxinzelelo lwe-static yi-12Pa;phezulu Uxinzelelo lwe-static ekuphumeni kweyunithi yoxinzelelo lwe-static kumthamo womoya olinganisiweyo awukho ngaphantsi kwe-30Pa.
