投資回收期
現(xiàn)以貴公司改造兩套中的一套為例來計(jì)算:功率為110KW,總投資額為53508.00元,公司運(yùn)作情況為日均工作24小時(shí),負(fù)荷率取0.87,電費(fèi)為0.8元/度,每月30天,節(jié)電率20%那么:
月節(jié)電費(fèi)=總功率×負(fù)荷率×月運(yùn)行時(shí)間×電價(jià)×節(jié)電率
=90×0.87×24×30×0.8×20%
=9020(元)
年節(jié)電費(fèi)=月節(jié)電費(fèi)×12個(gè)月
=9020×12
=108240(元)
投資回收期=投資總額÷月節(jié)電費(fèi)
=53508÷9020︽6個(gè)(月)
由此可見約需六個(gè)月就可以收回投資。
