Ngaba kuyimfuneko ukuthenga i-Fresh Air ERV?

Masilinganiseumoya opholileI-ERVenomoya ophezulu we-500CMH ngaphandle kokufumana amandla apheleleyo. Ukuze kucutshungulwe umoya omtsha kwi-35 degrees Celsius kunye nomswakama we-70% ukuya kwi-20 degrees Celsius kwaye uwuse egumbini, kufuneka amandla okupholisa e-7.4KW

Iindleko zombane ngaphandle kokubuyiselwa kwamandla

Ingcinga: Umoya opholileyo kukusetyenziswa kwamandla kwinqanaba lokuqala, oko kuthetha ukuba umoya opholileyo usebenzisa i-1KW yombane ukuvelisa amandla okupholisa angama-3 KW.

Ukusetyenziswa kwamandla kwe-air conditioner ukuthwala umthwalo womoya omtsha iyure enye yi-2.4 kWh (7.4/3=2.4)

Umrhumo wombane ubalwa ngokomyinge we-$0.1 nge-kilowatt ngeyure. Emva kokuvula umoya omtsha, i-air conditioner itya umbane ongaphezulu nge-$0.24 ngeyure kunesiqhelo (ukusetyenziswa kombane * ixabiso lombane)

Inkqubo yomoya omtsha idla ngokufuna ukuvulwa iiyure ezingama-24 ngosuku, nto leyo eyi-24 * 0.24 = 5.76 iidola zaseMelika (ixesha lokusetyenziswa * ixabiso leyunithi yokusetyenziswa kombane/iyure)

Iindleko zombane ze-air conditioner zokuthwala umthwalo womoya omtsha ngexesha lokusebenza kweenyanga ezintathu zefeni yomoya omtsha yasehlotyeni yi-5.76 * 90 days=518.4 USD (ukusetyenziswa kwamandla imihla ngemihla * iintsuku zokusetyenziswa)

Ixabiso lombanengamandlaukuchacha

Ukusebenza kakuhle kokubuyisela ubushushu komoya omtsha ngokubanzi kumalunga nama-60%.

Ukuba ifeni yomoya omtsha inokubuyiselwa kobushushu, yi-2073 * 0.1 = 207.3 iidola zaseMelika (ubungakanani bombane osetyenziswayo * ukusebenza kakuhle kokubuyiselwa kobushushu)

Iindleko zombane ezigcinekayo

Ngamafutshane, zombini xa kukho ubushushu obubuyisiweyo okanye ngaphandle kwabo zingonga umbane we-air conditioner nge-518.4-311.04=207.3 USD

Ngexesha leenyanga ezintathu zasehlotyeni, inkqubo yokungenisa umoya omtsha enokubuyisela ubushushu obupheleleyo isincede songe i-$207.3 kwiibhili zombane. Ngoko ke, ngaba i-ERV iseyirhafu yobukrelekrele?

Umsebenzi wokutshintshiselana kwe-enthaly yomoya omtsha udlala indima ebalulekileyo ekuphuculeni umgangatho wokusingqongileyo ngaphakathi kunye nokugcinwa kwamandla kunye nokunciphisa ukukhutshwa komoya.
