Abstract
Because it is necessary to know the influence of groundwater advection on performance of vertical geothermal heat exchanger (GHE), coupled heat conduction and advection experiments on soil were implemented. These experiments referred to the influence of GHE heat load in saturated soil without seepage on the temperature contour of surrounding soil, and the influence of groundwater flowrate, initial soil temperature, and GHE heat load in soil with seepage on temperature field of soil, respectively. The experimental result shows when the ground source heat pump (GSHP) system is used in the zone with hot summer and cold winter, or sub-tropical zone, it is better to adopt GSHP-cooling tower hybrid system, or bury the GHE in zone with high groundwater flowrate for system's long term efficient operation.
