摘　　要：对严寒地区地源热泵实际工程的供暖/供冷季的系统流量、供回水温度、机械功率等参数进行了测试,通过对供暖/供冷测试数据的分析,诊断系统目前存在的问题及耗能情况,并通过GS-1.0对系统运行20年后地下土壤温度变化情况进行模拟,预测系统将来可能出现的问题。经过对实际工程的分析发现,严寒地区地源热泵系统不仅存在地下热不平衡问题,设备的选型偏差、埋管区域的不合理运行管理同样造成系统能耗升高。The parameters of heating/cooling season of system flow rate, water temperature, mechanical power and indoor temperature and humidity were tested in the cold region of ground source heat pump engineering. Through the analysis of the heating/cooling test data, some problems in current system and energy consumption were found. To predict possible problems of the system in the future, the change of the underground soil temperature after system running 20 years through the GS - 1.0 was simulated. Analyzing the practical engineering, the ground source heat pump system is found that not only is there the underground hot imbalance, but also equipment selection and unreasonable operation and management of buried pipe area will increase system energy consumption in cold region.
