Kia whakatauira tatou ahau houERVme te nui o te rere o te hau o te 500CMH me te kore o te whakaora kaha katoa. Ki te tukatuka i te hau hou i te 35 nga nekehanga Celsius me te 70% te haumākū ki te 20 nga nekehanga Celsius me te tuku atu ki te ruuma, me 7.4KW te kaha whakamahana.
Te utu hiko kaore he whakaora hiko
Te whakaaro: Ko te whakamaaramatanga o te hau he taumata tuatahi o te kohi hiko, ko te tikanga ka pau te 1KW o te hiko o te rangi ki te whakaputa i te 3 KW o te kaha whakamahana.
Ko te kohi hiko o te whakamahana hau hei kawe i te hau hou mo te haora kotahi he 2.4 kWh (7.4/3=2.4)
Ka tatauhia te utu hiko ki te $0.1 mo ia haora kilowatt. I muri i te whakakā i te hau hou, ka pau te 2.4 * 0.1 = $0.24 te nui ake o te hiko mo ia haora i mua (te paunga hiko * utu hiko)
Ko te tikanga o te punaha hau hou me huri ki te 24 haora ia ra, ko te 24 * 0.24=5.76 US taara (te wa whakamahi * te utu mo te paunga hiko/haora)
Ko te utu hiko mo te hau hau ki te kawe i te uta hau hou i roto i nga marama e toru-marama o te wa mahi o te raumati hau hou, 5.76 * 90 ra = 518.4 USD (te paunga hiko o ia ra * ra whakamahi)
Utu hikome te kahawhakaora
Ko te kaha whakaora wera o te hau hau hou i te nuinga o te 60%.
Mena he wera te wera o te mea powhiriwhiri hau hou, ko te 2073 * 0.1=207.3 US taara (te nui o te kai hiko * te kaha whakaora wera katoa)
Nga utu hiko ka taea te penapena
Hei whakarāpopototanga, ka taea e koe te whakaora i te wera me te kore te whakaora i te hiko o te rangi ma te 518.4-311.04=207.3 USD
I roto i nga marama e toru o te raumati, na te punaha whakamahana hau hou me te whakaora wera katoa i awhina i a matou ki te penapena $207.3 mo nga pire hiko. Na, he taake mohio tonu a ERV?
Ko te mahi whakawhiti enthaly o te hau hau hou e whai waahi nui ana ki te whakapai ake i te kounga o te taiao o roto me te tiaki hiko me te whakahekenga.
