摘　　要：基于GB/T18430.1—2007《蒸气压缩循环冷水(热泵)机组第1部分:工业或商业用及类似用途的冷水(热泵)机组》中综合部分负荷性能系数IPLV的测试方法,分析水冷式冷水机组不能卸载到75%,50%和25%的部分负荷点工况的IPLV计算和测试方法,结合现有的2种计算部分负荷点冷却水进口温度的方法,提出采用分段线性插值函数和Lagrange插值多项式计算冷却水进口温度,并将试验数据与这4种计算方法进行对比分析,结果表明采用分段线性插值函数计算冷却水进口温度能够较好地反映冷水机组的实际运行情况。Based on the test methods of integrated part load value（IPLV）stated in GB/T18430.1-2007 Water chilling（heat pump）packages using the vapor compression cycle—Part 1：Water chilling（heat pump）packages for industrial commercial and similar application,the calculation and test methods of integrated part load value（IPLV）for the water chillers which can＇t unload to the part load operation points of75%,50% and 25% are analyzed.Combined with two kinds of existing calculation method for the inlet temperature of cooling water under part load operation condition,the linear interpolation function and Lagrange interpolation polynomial are developed to calculate the inlet temperature of cooling water.These four kinds of method are also compared with the test results.The results show that the inlet temperature of cooling water obtained by the linear interpolation function can well represent the actual operation situation of the water chiller.
