Summary

This paper presented both the numerical simulations and experiments on the thermal performance of U-vertical ground coupled heatexchanger (UGCHE). The variation of the ground temperature and heat balance of the system were analyzed and compared in differentoperation modes in the numerical simulation. Experiments on the operation performance of the ground-coupled heat pump (GCHP) with the UGCHE were carried out. It shows that the ground source can be used as the heat source/sink for GCHP systems to have higher efficiency in saving energy. To preserve the ground resource for the sustainable utilization as heat source/sink, the heat emitted to ground and heat extracted from ground should be balanced.
