Ingabe Kuyadingeka Ukuthenga I-Fresh Air ERV?

Ake silingiseumoya omushaI-ERVenomoya ophezulu ongu-500CMH ngaphandle kokubuyiselwa kwamandla okuphelele. Ukuze kucutshungulwe umoya omusha kuma-degree Celsius angu-35 kanye nomswakama ongu-70% kuya kuma-degree Celsius angu-20 bese uwuletha ekamelweni, kudingeka umthamo wokupholisa ongu-7.4KW

Izindleko zikagesi ngaphandle kokubuyiselwa kwamandla

Ukuqagela: Umoya opholile uwukusetshenziswa kwamandla okuseqophelweni lokuqala, okusho ukuthi umoya opholile usebenzisa ugesi ongu-1KW ukuze ukhiqize amandla okupholisa angu-3 KW.

Ukusetshenziswa kwamandla kwe-air conditioner ukuthwala umthwalo womoya omusha ihora elilodwa kungu-2.4 kWh (7.4/3=2.4)

Imali kagesi ibalwa ngokwesilinganiso esingu-$0.1 nge-kilowatt ngehora. Ngemva kokuvula umoya omusha, i-air conditioner idla ugesi ongaphezu kuka-$0.24 ngehora kunokuvamile (ukusetshenziswa kukagesi * intengo kagesi)

Uhlelo lomoya omusha luvame ukudinga ukuvulwa amahora angama-24 ngosuku, okungu-24 * 0.24 = amadola aseMelika angu-5.76 (isikhathi sokusebenzisa * intengo yeyunithi yokusetshenziswa kwamandla/ihora)

Izindleko zikagesi ze-air conditioner ukuze ithwale umthwalo womoya omusha phakathi nesizini yokusebenza kwezinyanga ezintathu yefeni yomoya omusha yasehlobo, ziyi-5.76 * izinsuku ezingama-90 = 518.4 USD (ukusetshenziswa kwamandla nsuku zonke * izinsuku zokusetshenziswa)

Izindleko zikagesingamandlaukululama

Ukusebenza kahle kokubuyisa ukushisa komoya omusha ngokuvamile kungama-60%.

Uma ifeni yomoya omusha inokubuyiselwa kokushisa, ingu-2073 * 0.1 = 207.3 amadola aseMelika (inani likagesi elisetshenziswayo * ukusebenza kahle kokubuyiselwa kokushisa okuphelele)

Izindleko zikagesi ezingongekayo

Ngamafuphi, kokubili ngokubuyisela ukushisa nangaphandle kokubuyisela kungasindisa ugesi womoya opholile ngo-518.4-311.04=207.3 USD

Phakathi nezinyanga ezintathu zasehlobo, uhlelo lokungenisa umoya omusha olunokubuyisa ukushisa okugcwele lusisize songe u-$207.3 ezikweletini zikagesi. Ngakho-ke, ingabe i-ERV iseyintela yezobunhloli?

Umsebenzi wokushintshana kwe-enthaly womoya omusha udlala indima ebalulekile ekuthuthukiseni ikhwalithi yezemvelo yangaphakathi kanye nokongiwa kwamandla kanye nokunciphisa ukukhishwa komoya.
