污水源热泵机组冬季运行工况实测与分析

Measurement and analysis of operating conditions of sewage source heat pump units in winter

以采用城市原生污水为热泵冷热源的北京悦都大酒店的热泵机组为研究对象,测试了机组的污水进出口温度,蒸发器侧、冷凝器侧的进出口温度和压缩机的耗电量,根据测试数据考察了热泵机组在以城市污水为热源时的工作性能。测试期间机组运行稳定,冬季的平均制热性能系数COP为3.71,测试分析结果可供污水源热泵系统的设计和工程应用参考和借鉴。

Taking the urban sewage source heat pump units in Beijing Yuedu Hotel as study object, tests the inlet and outlet temperatures of the sewage, evaporator and condenser and the power consumption of the compressor. Based on the testing data, explores the operating performance of the heat pump units with urban sewage as heat source. During the testing period, the heat pump units operate steadily and the average coefficient of performance in heating conditions is 3.71. The results can be used for a reference in design and engineering application of sewage source heat pump systems.
