摘　　要：对浙北地区某地源热泵工程土壤换热性能进行了实验测试,结果显示,浙北地区冬季最冷月地下土壤初始温度稳定在17.0℃左右,远高于室外环境温度;土壤的平均导热系数为1.73 W/(m.℃),有较强的地下换热能力,适合做地源热泵系统;对60m深的单U形式地下换热器进行换热性能测试,夏季单根盘管散热量3666W,冬季单根盘管散热量2508W,能满足系统工作要求。The heat transfer characteristics of ground source in Ground Source Heat Pump （GSHP） in Northem Zhejiang were experimentally measured. The experimental results showed that the initial ground source temperature in the coldest month was approximately 17.0℃, which was significantly higher than the temperature of the outside environment. The mean thermal conductivity of the ground source was 1.73W/（m· ℃）. It indicated that the ground source had good heat transfer capacity and could be used for the ground source heat pump system. The experimental measurement of the heat transfer coefficient was also conducted on a single U type underground heat exchanger at the depth of 60 m. The experimental results showed that the heat dissipating capacity of the single pipe were 3666W in summer and 2508 W in winter, respectively. The heat dissipating capacity could meet the requirement of the ground source heat pump system.
