Long-term energy storage mechanism for heating purposes

摘要

An underground liquid reservoir is arranged in the centre of a complex store (33) which comprises the liquid reservoir and the adjacent surrounding area (53) as storage capacities, the wall (51) of the liquid reservoir, which can be moved to approx. minus 15 DEG C having a low heat transfer resistance. Such a construction yields a high degree of economy in conjunction with a low space requirement and low vulnerability. In the case of soils having low water content, a high-energy plastic surrounding area is laid down made from mineral material and water embedded in water-tight plastic webs and adjoining the natural surrounding area. <IMAGE>
