| Abstract: | Quasi-3D model and numerical simulation method were used to analyze thermal interference between pipes of double U-tube geothermal heat exchanger.Intervals of pipes and heat conductivity of borehole grout were studied to discuss their influences on thermal interference.Then measures for reducing thermal interference were proposed. |
| Keywords: | ground source heat pump double U-tube geothermal heat exchanger thermal interference |
