Kodi Ndikofunikira Kugula Fresh Air ERV?

Tiyeni tiyerekezerempweya wabwinoERVndi mpweya wokwanira kufika pa 500CMH popanda mphamvu zonse zobwezeretsera. Kuti mugwiritse ntchito mpweya watsopano pa madigiri 35 Celsius ndi chinyezi cha 70% kufika pa madigiri 20 Celsius ndikuupereka m'chipinda, mphamvu yozizira ya 7.4KW ikufunika.

Mtengo wamagetsi popanda kubwezeretsanso mphamvu

Kuganiza: Mpweya woziziritsa ndi mphamvu yogwiritsidwa ntchito pamlingo woyamba, zomwe zikutanthauza kuti mpweya woziziritsa umagwiritsa ntchito 1KW yamagetsi kuti upange 3 KW ya mphamvu yozizira.

Mphamvu yomwe mpweya woziziritsa umagwiritsira ntchito kuti unyamule mpweya wabwino kwa ola limodzi ndi 2.4 kWh (7.4/3=2.4)

Ndalama yamagetsi imawerengedwa pa avareji ya $0.1 pa kilowatt ola limodzi. Mukayatsa mpweya wabwino, choziziritsiracho chimagwiritsa ntchito magetsi ochulukirapo 2.4 * 0.1 = $0.24 pa ola limodzi kuposa masiku onse (magetsi omwe amagwiritsidwa ntchito * mtengo wamagetsi)

Makina opumira mpweya wabwino nthawi zambiri amafunika kuyatsidwa maola 24 patsiku, zomwe ndi 24 * 0.24 = 5.76 madola aku US (nthawi yogwiritsira ntchito * mtengo wamagetsi wogwiritsidwa ntchito/ola)

Mtengo wamagetsi wa choziziritsira mpweya kuti chizinyamula mpweya wabwino mkati mwa miyezi itatu yogwira ntchito ya fan ya mpweya wabwino wachilimwe ndi, 5.76 * masiku 90 = 518.4 USD (magetsi omwe amagwiritsidwa ntchito tsiku lililonse * masiku ogwiritsira ntchito)

Mtengo wamagetsindi mphamvukuchira

Mphamvu yobwezeretsa kutentha kwa mpweya wabwino nthawi zambiri imakhala pafupifupi 60%.

Ngati fani ya mpweya wabwino ili ndi mphamvu yobwezeretsa kutentha, ndi 2073 * 0.1 = 207.3 madola aku US (ndalama zomwe magetsi amagwiritsidwa ntchito * mphamvu yonse yobwezeretsa kutentha)

Ndalama zamagetsi zomwe zingasungidwe

Mwachidule, zonse ziwiri, kaya ndi kutentha komwe kukubwera komanso popanda kutentha, zimatha kusunga magetsi oziziritsa mpweya ndi 518.4-311.04 = 207.3 USD.

M'miyezi itatu yachilimwe, makina opumira mpweya watsopano okhala ndi kutentha kwathunthu adatithandiza kusunga ndalama zokwana $207.3 pamagetsi. Ndiye, kodi ERV ikadali msonkho wanzeru?

Ntchito yosinthana kwa mpweya wabwino m'nyumba imagwira ntchito yofunika kwambiri pakukweza ubwino wa chilengedwe komanso kusunga mphamvu ndi kuchepetsa utsi.
