摘　　要：IPLV作为综合评价冷水机组性能的重要指标之一,本文根据控制逻辑的不同,介绍风冷式与蒸发式冷水机组IPLV典型测试方法,分析测试要求工况的差异,拟合2种机型测试冷凝侧空气温度对应负荷率的线性方程,并介绍模拟机组水侧污垢系数修正温差计算方法。IPLVis an important index of the performance evaluation of chillers.The typical test methods of IPLVfor air-cooled and evaporative chillers are introduced according to different control logics,and the difference of test requirements is analyzed.The linear equations of these two models are fitted to test the percentage of air temperature on the condensation side,and the calculation method of the temperature difference correction of the dirt coefficient on the water side for the simulating unit is introduced.
