Abstract

The ground heat storage system has a heat storage medium (13) within the soil (2) with an insulation and sealing system (8-10) which also protects the medium against lateral pressures from the surrounding soil and also vertical pressures on it. The heat storage medium can be foam concrete or a granulate which holds water to store the heat, together with coiled pipe heat exchangers.

Description

Um das zeitweise Überangebot von Energie (z. B. Solarenergie vom Sommer in den Winter oder Wärmeenergie aus Umwandlungsprozessen) speichern zu können, sind Tanks mit dem Speichermedium Wasser oder ähnlich üblich. Diese bestehen aus einem aufwendig hergestellten Tank (Stahlbeton, Stahl), der dann gedämmt wird. Die im Patentanspruch angegebene Erfindung besteht nun darin, diese statischen Aufgaben des Tanks dadurch zu ersetzen, daß ein Wärmespeichermedium gewählt wird, das diese Aufgaben (Erddruck und Vertikallasten) übernimmt. Dies kann beispielsweise durch Wiederbefüllen des Speichers mit dem Bodenaushub selbst geschehen. Alternativ zum statisch tragenden Wärmespeichermedium ist auch ein Material denkbar, daß das Speichermedium (z. B. Wasser) in sich aufnimmt und selbst als Stützkörper fungiert (z. B. Blähton oder Granulat). Zur Isolierung bzw. Abdichtung ist ein Auskleiden der Baugrube mit Folie oder einer sonstigen Dichtungsschicht und einer druckfesten Wärmedämmung vorgesehen. Der Wärmeenergieeintrag ist durch wärmetauschende Spiralleitungen im unteren bzw. oberen Bereich des Speichers oder durch Förderung des flüssigen Speicheranteils möglich.The temporary oversupply of energy (e.g. solar energy from summer to winter or heat energy from conversion processes) are tanks with the Storage medium water or similar usual. These consist of an elaborate manufactured tank (reinforced concrete, steel), which is then insulated. The in the claim specified invention is now to achieve these static tasks of the tank replace that a heat storage medium is chosen that performs these tasks (earth pressure and Vertical loads). This can be done, for example, by refilling the memory the excavation itself. As an alternative to the statically load-bearing one Heat storage medium is also conceivable a material that the storage medium (e.g. Water) and absorbs itself as a supporting body (e.g. expanded clay or granulate). For insulation or sealing, the building pit must be lined with foil or a other sealing layer and pressure-resistant thermal insulation. The Thermal energy input is through heat-exchanging spiral pipes in the lower or upper Area of the storage or by promoting the liquid storage portion possible.

Vorteilebenefits

Durch die stützende Wirkung des Speichermediums entfällt der aufwendige Bau eines Tankes. Zudem gibt es fast keinen unnötigen Baugrubenaushub. Die Abdichtung kann durch eine dünne wasserdichte Schicht gebildet werden. Der Tank ist durch Überschüttung mit Erde bepflanzbar bzw. bebaubar und verschwindet im Boden. Der Eingriff in den Energiehaushalt des Bodens bzw. des Grundwassers ist gering. Durch die Bauweise können kostengünstig große Speicher hergestellt werden, was den Nachteil der relativ geringen Speicherfähigkeit des Bodens ausgleicht.The supportive effect of the storage medium means that there is no need to build one Tanks. In addition, there is almost no unnecessary excavation excavation. The seal can be done by a thin waterproof layer can be formed. The tank is covered with earth can be planted or built on and disappears into the ground. The intervention in the energy balance of the soil or groundwater is low. The design can be inexpensive large memories are produced, which has the disadvantage of the relatively low storage capacity balances the soil.
