OPERATION MODE AND HEAT PERFORMANCE OF ENERGY DRILLED PILES

ABSTRACT
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.
