AB - Energy pile takes a full use of shallow geothermal, the heat exchanger is  buried in the foundation extract the ground heat source for heating and  cooling of the upper building. Firstly, the geothermal potential of the  region is calculated. Then, the heat transfer efficiency of pile foundation  under different operation conditions is tested by field test. Finally, the  numerical simulation software is used to analyze and compare the field  measured results with the numerical simulation results to simulate the heat  transfer efficiency of the heat exchange pile under different operation  modes. The results shows the heat transfer efficiency of the double U  connected tubes is suitbable used in drilled pile, and the heat transfer  capacity of the energy piles does not decrease significantly during a year  operation mode and even long.
