对一台以HFC125为工质的变频热泵在制冷剂临界点附近运行进行了实验研究。研究了不同压缩机转速、水流量和冷凝器热水温度下系统的性能系数和效率。确定了各部件的火用亏损。结果表明，随着热水温度的升高，系统的火用效率先增大后减小，系统性能系数不断减小。研究结果可为该类型热泵系统的优化设计和运行提供有益的指导。
An experimental study on an inverter heat pump with HFC125 operating near the refrigerant critical point was carried out. The coefficient of performance (COP) and exergy efficiency of the system were investigated under different compressor speed, water flow rate and different hot water temperatures of the condenser. The exergy defect in each component was determined. The results show that the exergy efficiency of the system increases initially and then decreases while the COP constantly decreases with the increase of the temperature of hot water. The results of this study can provide useful guidelines for optimal design and operation of this type of heat pump system in its present or future applications.
