摘要
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。
The IPLV is one important indicator used for evaluating the seasonal operation performance of chiller .While ,different building types and the chiller numbers in specific application have impacts on the actual energy consumption of the chiller at running time;ambient temperature directly affects compressor ratio ,w hich leads to different unit efficiencies .So the end user’s actual power usage should be determined by actual running conditions of chiller .T he proposed test conditions are calculated using annual climate data and typical building’s annual load profile .Based on the proposed test conditions ,the unit’s actual performance are tested ,in order to offer actual power usage for end users ,which can target a more reasonable decision for chiller selection .
