Abstract
A thermally insulating forward-flow pipe (27) is connected to a pump (28) mounted inside a borehole (32). The forward-flow pipe (27) and pump (28) are surrounded inside the borehole (32) by a shroud pipe (34, 34a) which is open at the bottom and outside and around which is a return-flow region (38) for return water. The return-flow region contains return-flow pipes (40) connected to an energy exchanger (4) and a porous filling (48). At the bottom (30) of the borehole (32), the return-flow region is connected via lateral inlet apertures (52) in the shroud pipe (34, 34a) to the inner space of the shroud pipe. To make the facility more efficient, the shroud pipe (34) below the pump (28) leads into a section (34a) with a reduced internal cross-section. (Fig. 1)
