1. A heat exchange system between a building and the Earth's subsurface, comprising a closed loop comprising at least one device installed in said subsurface for heat exchange with subsurface, connecting pipes, and at least one device installed in said building for heat exchange with building, the at least one device installed in the subsurface being connected by the connecting pipes to the at least one device installed in the building, the closed loop comprising at least one circulation pump for circulating a fluid through said closed loop, the at least one circulation pump comprising a progressing cavity pump, characterized in that the fluid comprises capsules containing phase change materials).
