Me whakatauira tātou i tētahihau houERVme te hau mōrahi o te 500CMH me te kore e whakaora katoa i te pūngao. Hei tukatuka i te hau hou i te 35 nekehanga Celsius me te 70% haumākū ki te 20 nekehanga Celsius me te tuku atu ki te rūma, me whai kaha whakamatao o te 7.4KW.
Te utu hiko me te kore whakaora pūngao
Whakaaro: Ko te hauhautanga he taumata tuatahi o te whakamahinga pūngao, arā, ka pau te 1KW o te hiko i te hauhautanga hei whakaputa i te 3 KW o te kaha whakamatao.
Ko te kaha e pau ana i te hauhautanga hei kawe i te hau hou mō te haora kotahi he 2.4 kWh (7.4/3=2.4)
Ko te utu hiko ka tatauhia i te toharite o te $0.1 i te kilowatt-hāora. I muri i te whakakā i te hau hou, ka pau i te hauhautanga he 2.4 * 0.1 = $0.24 te hiko nui ake i te tikanga (te whakapaunga hiko * te utu hiko)
Me whakakā te pūnaha hau hou i ngā hāora 24 o te rā, arā, 24 * 0.24=5.76 tāra US (te wā whakamahinga * te utu mō te whakamahinga hiko/hāora)
Ko te utu hiko mō te hauhautanga hei utu i te hau hou i te wā e toru marama te roa o te mahi a te pā hau hou o te raumati, 5.76 * 90 rā = 518.4 USD (te whakapaunga hiko o ia rā * ngā rā whakamahinga)
Te utu hikome te pūngaowhakaoranga
Ko te whai huatanga o te whakaora wera o te hau hou e tata ana ki te 60%.
Mena he whakaora wera kei roto i te pā hau hou, ko te 2073 * 0.1 = 207.3 tāra US (te nui o te hiko e pau ana * te pai o te whakaora wera katoa)
Ngā utu hiko penapena
Hei whakarāpopototanga, mā te whakaora wera me te kore whakaora wera ka taea te penapena hiko hauhautanga mā te 518.4-311.04=207.3 USD.
I roto i ngā marama e toru o te raumati, nā te pūnaha hauhautanga hou me te whakaora wera katoa i āwhina mātou ki te penapena i te $207.3 i roto i ngā pire hiko. Nō reira, he taake mōhiohio tonu te ERV?
He mea nui te mahi whakawhiti enthaly o te whakapūhau hau hou ki te whakapai ake i te kounga o te taiao o roto, me te tiaki pūngao me te whakaiti i ngā tukunga.
