Ingabe Kuyadingeka Ukuthenga I-Fresh Air ERV?

Ake silingise aumoya omushaERVnokugeleza komoya okuphezulu okungu-500CMH ngaphandle kokutholwa kwamandla okuphelele. Ukucubungula umoya omusha ku-35 degrees Celsius kanye nomswakama ongu-70% ukuya ku-20 degrees Celsius futhi uwulethe ekamelweni, umthamo wokupholisa ongu-7.4KW uyadingeka.

Izindleko zikagesi ngaphandle kokuthola amandla

Okucatshangwayo: I-air conditioning iyizinga lokuqala lokusebenzisa amandla, okusho ukuthi isipholisa-moya sisebenzisa u-1KW kagesi ukukhiqiza u-3 KW womthamo wokupholisa.

Ukusetshenziswa kwamandla kwesiphephelo somoya ukuthwala umoya omusha ngehora elilodwa ngu-2.4 kWh (7.4/3=2.4)

Inkokhelo kagesi ibalwa ngokwesilinganiso esingu-$0.1 ngehora le-kilowatt. Ngemva kokuvula umoya omusha, isipholile sisebenzisa ugesi ongu-2.4 * 0.1 =$0.24 ngaphezulu kukagesi ngehora kunokuvamile (ukusetshenziswa kukagesi * inani likagesi)

Isistimu yomoya ohlanzekile ngokuvamile idinga ukuvulwa amahora angu-24 ngosuku, okungu-24 * 0.24=5.76 US dollars (isikhathi sokusetshenziswa * inani leyunithi yokusetshenziswa kwamandla/ihora)

Izindleko zikagesi ze-air conditioner ukuze zithwale umthwalo womoya omusha phakathi nesizini yokusebenza yezinyanga ezintathu zesiphephetha-moya sasehlobo zingu-5.76 * 90 days=518.4 USD (ukusetshenziswa kwamandla kwansuku zonke * izinsuku zokusetshenziswa)

Izindleko zikagesingamandlaukululama

Ukusebenza kahle kokuthola ukushisa kokungenisa komoya omusha ngokuvamile kucishe kube ngu-60%.

Uma isiphephetha-moya esihlanzekile sinokululama kokushisa, singama-2073 * 0.1=207.3 amadola ase-US (inani elisetshenziswa ugesi * inani eliphelele lokutakula ukushisa kahle)

Izindleko zikagesi ezilondolozwayo

Kafushane, kokubili ngokuthola ukushisa noma ngaphandle kokuthola ukushisa kungasindisa ugesi we-air conditioning ngo-518.4-311.04=207.3 USD

Phakathi nezinyanga ezintathu zasehlobo, isistimu yokungenisa komoya omusha enokubuyiselwa okuphelele kokushisa yasisiza songa u-$207.3 wezikweletu zikagesi. Ngakho-ke, ingabe i-ERV iseyintela yezobunhloli?

Umsebenzi wokushintshanisa i-enthaly wokungenisa komoya omusha udlala indima ebalulekile ekuthuthukiseni ikhwalithi yemvelo yasendlini nokongiwa kwamandla kanye nokunciphisa ukungcola.
