Because of the advantage on energy saving and environmental sustainable development, the ground source heat pump (GSHP) system has received the widespread attention and application in recent years.However,the difference between cooling load in summer and heating load in winter is obvious in most areas of our country,so it can cause the heat accumulation around ground heat exchanger,which will result in degradation of system performance and increment of system operating costs.To solve the problem of thermal imbalance,it is necessary to research the soil temperature field around the buried pipes in the process of system operation.This paper begins with a review of the studies about the ground source heat pump systems.This is followed by a review of various methods of enhancing the performance of heat pumps based on the thermal imbalance.And then,this paper shows some studies about ground source heat pump systems based on the groundwater seepage.
