Ngaba Kuyimfuneko Ukuthenga I-ERV yoMoya oNtsha?

Masilinganise aumoya opholileERVkunye ne-airflow ephezulu ye-500CMH ngaphandle kokubuyiswa kwamandla ngokupheleleyo. Ukuseta umoya omtsha kwi-35 degrees celsius kunye ne-70% yokufuma ukuya kuma-20 degrees celsius kwaye uhambise kwigumbi, umthamo wokupholisa we-7.4KW uyafuneka.

Iindleko zombane ngaphandle kokubuyisela amandla

Ingqikelelo: I-air conditioning yinqanaba lokuqala lokusetyenziswa kwamandla, oku kuthetha ukuba i-air conditioning isebenzisa i-1KW yombane ukuvelisa i-3 KW yomthamo wokupholisa.

Ukusetyenziswa kwamandla omoya wokupholisa umoya ukuthwala umoya omtsha ngeyure enye yi-2.4 kWh (7.4/3=2.4)

Umrhumo wombane ubalwa kumyinge we-$0.1 ngeyure yekilowathi. Emva kokuvula umoya omtsha, i-air conditioner isebenzisa i-2.4 * 0.1 = $ 0.24 ngaphezulu kombane ngeyure kunesiqhelo (ukusetyenziswa kombane * ixabiso lombane)

Inkqubo yomoya omtsha idla ngokufuna ukuvulwa iiyure ezingama-24 ngosuku, eyi-24 * 0.24=5.76 yeedola zase-US (ixesha lokusetyenziswa * ixabiso leyunithi yokusetyenziswa kwamandla/iyure)

Iindleko zombane ze-air conditioner ukuze zithwale umthwalo womoya omtsha ngexesha leenyanga ezintathu zokusebenza ze-fan yomoya omtsha wehlobo, 5.76 * 90 days=518.4 USD (ukusetyenziswa kwamandla yonke imihla * ukusetyenziswa kweentsuku)

Iindleko zombanengamandlaukuchacha

Ukusebenza kakuhle kokubuyisela ubushushu bokungenisa komoya omtsha kuqhelekile malunga ne-60%.

Ukuba i-fan yomoya omtsha inokubuyisela ubushushu, yi-2073 * 0.1=207.3 yeedola zase-US (ixabiso lokusetyenziswa kombane * ukusebenza kakuhle kokubuyisela ubushushu)

Iindleko zombane ezigcinwayo

Ngamafutshane, zombini kunye nangaphandle kokubuyiswa kobushushu kunokugcina umbane womoya womoya nge-518.4-311.04=207.3 USD

Ngexesha leenyanga ezintathu zasehlotyeni, inkqubo yokungenisa umoya omtsha kunye nokubuyisela ubushushu obugcweleyo yasinceda ukuba sigcine i-$ 207.3 kwiibhili zombane. Ke, ngaba i-ERV iseyirhafu yobukrelekrele?

Umsebenzi wokutshintshiselana nge-enthaly wokungenisa komoya omtsha udlala indima ebalulekileyo ekuphuculeni umgangatho wokusingqongileyo wangaphakathi kunye nokugcinwa kwamandla kunye nokunciphisa ukukhutshwa.
