Arrangement for effecting an energy exchange between earth soil and an energy exchanger
First Claim
1. An arrangement for effecting an energy exchange between earth soil and an energy exchanger, the arrangement comprising:
- a soil heat exchanger; and
supply and return flow conduits for connecting the soil heat exchanger with the energy exchanger,wherein the soil heat exchanger comprises;
a thermoinsulated supply flow duct arranged in a borehole formed in ground;
a pump provided at an end of the flow duct;
a shroud pipe surrounding the flow duct and the pump and having a section with a reduced inner cross-sectional area located beneath the pump and provided with a plurality of lateral inlet openings; and
a return flow region for return water located radially outwardly of the shroud pipe and including return flow pipe means, connectable with the return flow conduit, and a porous filling, the return flow region communicating, in a vicinity of a borehole bottom, with an interior of the shroud pipe through the lateral inlet openings provided in the shroud pipe section with the reduced inner cross-sectional area.
