Verwendung einer Sonde aus einer unten geschlossenen Doppelrohrtour

摘要

The geothermal system operates with water. A neutral, cold deionised water circuit is fed into a deep borehole (2) to be heated by contact with hot deep rock. The hot deionised water is then delivered directly to a central heating installation. Pref. The hot deionised water delivery takes placed on the principle of a water delivery store. A double pipeline (3,4), closed at the bottom, is inserted into the deep borehole. The inner, concentric, heat insulated line (4) has overflow parts, while the outer line (3) is of metallic, heat conductive type.
