摘　　要：指出在任何应用场合或运行工况下,冷水机组的综合部分负荷性能系数(IPLV)不能预测单台冷水机组的全年能耗,提出二种冷水机组全年能耗评估方案。分析ASHRAE90.1-2010对冷水机组的名义工况性能系数(COP)和IPLV限定值的要求,说明选择高效冷水机组时,宜注重COP比较并兼顾IPLV。It’s pointed out chiller IPLV can not be used to predict the chiller annual energy consumption for a chiller in any specific application or operating conditions. Two proposals of estimating the chiller annual energy consumption are introduced. The minimum value of chiller COP and IPLV required by ASHRAE 90.1-2010 is analyzed, and it is suggested to pay more attention to chiller COP than IPLV when selecting high efficiency chillers.
