污水源热泵制热工况的实际运行特性分析
Operating performance analysis on heating conditions of sewage source heat pumps
摘要：
通过对天津市一污水源热泵系统的监测，得到了冬季污水温度的变化范围、热泵系统的实际能效比与蒸发器和冷凝器的进出口水温。通过与热泵机组样本数据的比较，分析了普通水源热泵用作污水源热泵时的性能差异。指出了污水源热泵应用中存在的一些问题并给出了改进建议。

Abstract：
Obtains the changing range of sewage temperature, the actual energy efficiency ratio of heat pump system and the inlet and outlet temperatures of evaporator and condenser in winter by monitoring a sewage source heat pump system in Tianjin. Analyses the performance difference between sewage source heat pumps and water source heat pumps by comparing with the data given in some heat pump specifications. Presents the problems existed and gives corresponding suggestions.
