Bari mu kwaikwayiiska mai kyauERVtare da matsakaicin iskar iska ta 500CMH ba tare da cikakken murmurewa daga makamashi ba. Don sarrafa iska mai kyau a digiri 35 na Celsius da kuma 70% na zafi zuwa digiri 20 na Celsius da kuma isar da ita zuwa ɗakin, ana buƙatar ƙarfin sanyaya na 7.4KW.

Kudin wutar lantarki ba tare da dawo da makamashi ba

Zato: Na'urar sanyaya iska (sauya iska) ita ce amfani da makamashin matakin farko, wanda ke nufin cewa na'urar sanyaya iska tana amfani da wutar lantarki 1KW don samar da ƙarfin sanyaya 3KW.

Amfanin wutar lantarki na na'urar sanyaya daki don ɗaukar nauyin iska mai kyau na tsawon awa ɗaya shine 2.4 kWh (7.4/3 = 2.4)

Ana ƙididdige kuɗin wutar lantarki a matsakaicin dala $0.1 a kowace kilowatt a awa ɗaya. Bayan kunna iska mai kyau, na'urar sanyaya iska tana cinye wutar lantarki 2.4 * 0.1 = $0.24 fiye da yadda aka saba a kowace awa (yawan wutar lantarki * farashin wutar lantarki)

Tsarin iska mai tsafta yawanci yana buƙatar kunnawa awanni 24 a rana, wanda shine dala 24 * 0.24 = dala 5.76 na Amurka (lokacin amfani * farashin na'urar amfani da wutar lantarki/awa)

Kudin wutar lantarki da na'urar sanyaya daki za ta iya ɗauka a lokacin aiki na watanni uku na fanka mai sanyaya daki na lokacin bazara shine, 5.76 * kwanaki 90 = 518.4 USD (yawan amfani da wutar lantarki na yau da kullun * kwanakin amfani)
