摘要：
A ground source heat pump system (GSHPs) with under-ground vertical U-tube heat exchanger was performed in north-west suburb of Beijing. The underground vertical U-tube heat exchanger of the water temperature versus the time change was tested for cooling and heating. The results showed that the water temperature of underground vertical U-tube heat exchanger of the ground-source heat pump system is relatively stable, average heating coefficient COP is 3.1 with out-let temperature of U-tube heat exchanger is 5.5 similar to 8.8 degrees C in winter, and average cooling coefficient COP is 4.6 with out-let temperature of U-tube heat exchanger is 22 similar to 26 degrees C in summer, respectively, so the GSHPs is highly efficient and energy-saving for heating and cooling.
