摘　　要：分析了IPLV/NPLV的应用条件,指出了其作为一种效率评价标准存在的缺陷。由于IPLV/NPLV不能真实地代表一个制冷站的运行特性,故仅用于比较单台机组的卸载特性,不能预测配置变频器带来的经济效益。认为评价冷水机组的实际运行工况时,高负荷区运行工况点的能效格外重要,为了确保获得经济上和环境上最佳的方案,应采用准确的能耗分析工具。Analyses the application conditions of IPLV/NPLV,points out the defects of IPLV/NPLV being used as an efficiency evaluation standard.It does not accurately represent a chiller plant＇s operating characteristics,it can be used to compare unloading characteristics of chillers only,and it can not be used for predicting the economic savings by adding variable-speed drives.Considers that high-load operating points are extremely important when looking at the real operating points of chillers,and to ensure optimal solutions economically and environmentally,it is important to use accurate energy analysis tools.
