<p>The consuming unit is connected to a heat exchanger via a heat pump, for extracting heat from the ground. In setting up the installation, a re-usable material-displacement unit (1) is inserted into the ground (4). It has a tubular hollow lip unit (3) with a closable end face on the ramming side. Before this is withdrawn, a collector is inserted, in the form of a tubular closed container (5) with one or more inflows and outflows (6,7). The unit is then filled with a circulating medium. The sheathing displacement unit is then pulled out of the ground. The container can have corrugated walling. The simple procedure permits compact insertion of effective geothermal collectors, with min. excavation work.</p> |
