Abstract
in the paper, the influence of different inflow water rate and temperature on heat exchange performance of underground heat pump were discussed by experiment, two vital parameters was defined to measure the properties of ground heat exchanger: Energy Efficiency Coefficient and Heat Exchange Utility Time. The experimental results showed that whether in the winter or summer working condition, and the change of water temperature of buried tube inlet could not affect the trend of Energy Efficiency Coefficient changing with time, and reducing water velocity will help to enhance energy efficiency of buried tube, and improve the host operating efficiency.
