摘要

The heat recovery installation (34) comprises at least one energy well (26). Pressure-producing devices (38,42) periodically impart an excess pressure to the well water in relation to that of the ground water in the surrounding earth. This produces a movement of water backwards and forwards between the earth and the well, and in turn an increase in energy exchange.(2)
