Figure 11 reflects thermal recovery ability after the heating period operation of the heat pump.

The temperature of the the simulation (the end of the third shutdown period in the cycle). The temperature of the rock mass around the fractures was higher than other areas due to the supplementary heat rock mass around the fractures was higher than other areas due to the supplementary heat continuously brought by the fracture water. The energy carried by the fracture flow into continuously brought by the fracture water. The energy carried by the fracture flow into the rock mass significantly enhanced the thermal recovery ability in the rock mass. the rock mass significantly enhanced the thermal recovery ability in the rock mass.

During the heating operation (0–4 month), the decrease in the ground temperature in the rock mass with fractures was (0–4 month), the decrease in the ground temperature in the rock mass with fractures was gentler than that of the rock without a fracture.
