in Changsha City as example, the techno-economic performances of MFGSHP system were studied. The heat balance of the soil around the borehole heat exchanger and the characteristic of energy consumption...). The results show that the heat balance can be obviously improved by applying MFGSHP system, and the increase in soil temperature is reduced by 3.9℃ compared to the common GSHP system with the same borehole......
