The design and application of Ground Coupled Heat Pump (GCHP) was mainly based on the heat transfer performance of underground heat exchanger. An experimental system with different types of U-vertical ground coupled heat exchanger (UGCHE) in situ was set up, for example, single or double UGCHE with sandstone backfilled, and single UGCHE with cement backfilled. The research on the thermal behaviour of UGCHE in different types, and in various conditions, such as different soil properties, backfill material, number of borehole exchangers, and different operation modes was carried out in the paper.
