AB - The heat exchanger can use shallow geothermal energy to provide regional  heating and cooling demand in winter and summer. In this paper, a  large-scale public building is taken as the example, and the energy system  in the building is taken as the research object. Firstly, through the  collection of geothermal drilling geographic information and geothermal  data, the geothermal reserves and geothermal recoverable resources are  evaluated. Secondly, the cooling and heating demand of the building is  calculated by using HVAC simulation software. Then, the heat transfer  capacity of a single pile is evaluated and the layout scheme of the  underground heat exchange pile foundation of the building is given. The  actual heating effect of the heat exchange pile foundation system is  explored, and the heat transfer characteristics of heat exchange pile  foundation under different working conditions are compared and analyzed.  Finally, reasonable suggestions for the arrangement of heat exchange pile  foundation are given.
