摘要
详细分析了各种能耗指标的特点及适用场合 ,指出用一次能的能耗指标比二次能的更为科学 ,推荐采用当量燃料性能系数或当量电能性能系数作为比较两种制冷机的较佳能耗指标 ,还讨论了额定工况下的u值问题。
Analyses in detail the characteristics of severa l energy consumption indices and their applicabilities,points out that using th e one of ind ex of primary energy is more scientic than using the one of secondary energy,rec ommeds the c.o.p of equivalent fuel or the c.o.p. of electric energy as optimal energy consumption index,and discusses also the U-value under rated conditions.
