IPLV是目前广泛被用作评估冷水机组季节运行性能的重要指标,而机组运行的实际能耗受不同楼宇类型的影响,也受特定应用中冷水机组台(套)数的影响;环境温度直接影响机组压缩机的压缩比,从而影响机组的运行效率,所以终端用户的实际用电情况需要根据冷水机组的实际运行状态决定。本文利用历史全年气象数据和典型楼宇全年负荷数据计算出推荐测试工况,然后根据推荐的测试工况测试得到机组的实际性能,从而更准确地给出终端用户的实际用电情况,以更好地为机组选型提供参考决策。
IPLV is widely used as an important indicator to evaluate the seasonal performance of chiller units. The actual energy consumption of units is affected by different building types and is also affected by the number of chiller units (units) in a particular application. The ambient temperature directly affects Unit compressor compression ratio, thus affecting the unit’s operating efficiency, so the actual end-user electricity needs to be based on the actual operation of the chiller decision. In this paper, historical meteorological data and typical building annual load data to calculate the recommended test conditions, and then test the actual test results to the actual performance of the unit, so as to more accurately give the actual end-user electricity to Better for the selection of units to provide a reference decision.
