The Simulation Study on Buried Ground-Source Heat Pipe Transient Temperature Field Distribution
In order to provides the theory basis for the optimization design of ground source heat pump underground U-shaped buried tube, ANSYS software was used to simulate the temperature field distribution of GSHP buried tube summer cooling process. The dynamic simulation was base on analyzing the GSHP heat exchanger unsteady heat transfer model. Comparing the temperature field distribution radius in different soil heat transfer rate, the simulation results show that the buried tube heat transfer efficiency increases with soil coefficient of thermal conductivity, soil hot effect radius increased over time and tend to be gentle.
