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.
