摘　　要：对某住宅小区的地下水源热泵系统进行了连续三个冬季的运行监测.监测结果显示,地下水源热泵系统有着较高的供暖能效,但系统运行较长时间后能效会出现下降.通过对监测数据的分析,获得了机组容量、相同机组容量下的两台压缩机的不同容量组合和负荷侧进机组的水温对机组能效的影响规律,并提出了针对这三因素的优化运行策略.The operational conditions of a residential ground water source heat pump （GWHP ） system operating in three successive winters in Hanzhong were tested. Results show that the GWHP system has high heating energy efficiency, but its energy efficiency will decrease after it has been in operation for a long time. According to the analysis of the testing data, the laws affecting the capacity of unit, the combinations of different capacities of double compressors in condition of the same capacity of unit and the inlet temperature of condenser affecting the energy efficiency of unit are obtained. Meanwhile, the strategies of optimizing operation about these three factors are pro-posed.
