Trench collector for feeding and extraction of thermal energy from subsoil in preferential use as part of heat pump system, has pipes embedded in subsoil for transporting working fluid

摘要

The trench collector has pipes (6,7) embedded in the subsoil (1) for transporting a working fluid. The pipes are laid individually or in bundles in a trench (2) and run downward. The pipes are driven on both sides along their course in an impermeable foil (4). The foil is glued or sealed in the overlap area.
