Description

Die vorliegende Erfindung betrifft eine Primärenergiequelle für Wärmepumpen-Heizsysteme.The present invention relates to a primary energy source for heat pump heating systems.

Mehr und mehr gewinnt im Rahmen der Alternativenergien die Wärmegewinnung mittels Wärmepumpen-Heizsystemen, welche durch Abkühlung einer Wärmequelle, wie Aussenluft, Grundwasser, Flusswasser oder Erdreich kostenlose Umweltwärme nutzen, an Bedeutung.In the context of alternative energies, heat generation using heat pump heating systems, which use free environmental heat by cooling a heat source such as outside air, groundwater, river water or soil, is becoming increasingly important.

Solche Systeme sind bekannt.Such systems are known.

Aufgabe der vorliegenden Erfindung ist nun die Nutzung einer neuen Primärenergiequelle für solche bekannten Wärmepumpen-Heizsysteme, welche Aufgabe erfindungsgemäss zunächst dadurch gelöst wird, dass die, der Wärmeaufnahme dienende Flüssigkeitskollektorenanordnung des Primärenergiekreises des Wärmepumpen-Heizsystems in einem Bergwerkstollen oder Höhlenteil angeordnet ist und über einen Vorlauf und einen Rücklauf mit dem Wärmetauscher der Wärmepumpe in Strömungsverbindung steht.The object of the present invention is now to use a new primary energy source for such known heat pump heating systems, which object is initially achieved according to the invention in that the liquid collector arrangement of the primary energy circuit of the heat pump heating system used for heat absorption in a mine tunnel or Cave part is arranged and is in flow connection with the heat exchanger of the heat pump via a flow and a return.

zwar ist das Prinzip der Erdwärmetechnologie bekannt, wonach die vom Erdreich gespeicherte natürliche Wärme durch Erdsonden dem Boden entzogen und dem Wärmepumpen-Heizsystem zugeführt wird, wobei die Verwendung von Erdsonden aber relativ aufwendig und teuer ist.Although the principle of geothermal technology is known, according to which the stored from natural soil heat by E rdsonden wherein the use of borehole heat exchangers is extracted from the soil and the heat pump heating system is supplied, but relatively complicated and expensive.

Durch die erfindungsgemässe Einbringung einer Flüssigkeits- kollektorenanordnung in einen Bergstollen oder Höhlenteil kann der Aufwand wesentlich herabgesetzt und zudem der Wirkungsgrad ganz erheblich gesteigert werden, zumal dann, wenn im betreffenden Stollen statische Verhältnisse geschaffen werden.By incorporating a liquid collector arrangement according to the invention into a mountain gallery or cave part, the effort can be significantly reduced and the efficiency can be increased considerably, especially if static conditions are created in the tunnel concerned.

Dies kann beispielsweise dann erreicht werden, wenn die Flüssigkeitskollektorenanordnung aus mehreren Rohrwindungen besteht, welche in eine durch Schotten geschlossene Stollenkammer eintauchen. Für einen optimalen Wärmeübergang kann dabei zudem noch die Stollenkammer Mit Grundwasser gefüllt werden, womit sich eine sehr kostengünstige Nutzung einer sehr konstanten Stollentemperatur von oft 14 und mehr Grad erzielen lässt.This can be achieved, for example, if the liquid collector arrangement consists of a plurality of pipe windings which are immersed in a gallery chamber closed by bulkheads. For optimal heat transfer, the tunnel chamber can also be filled with groundwater, which enables a very cost-effective use of a very constant tunnel temperature of often 14 and more degrees.

Eine weitere, oft anwendbare und sehr vereinfachte Ausführungsvariante lässt sich zudem dann erreichen, wenn die Flüssigkeitskollektorenanordnung durch eine durch Schotten geschlossene, mit Grundwasser gefüllte und mit, ein Strö- mungslabyrinth bildende Zwischenwänden versehene Stollenkammer gebildet ist.Another often applicable and very simplified embodiment can also be achieved if the F lüssigkeitskollektorenanordnung is formed by a closed by bulkheads, filled with ground water and with a flow-labyrinth-forming partitions provided tunnel chamber.

Dadurch ist es möglich, das Grundwasser selbst als Wärmeträgerflüssigkeit zu verwenden.This makes it possible to use the groundwater itself as a heat transfer fluid.

Muss der Stollen begehbar sein oder bleiben, ist es ferner möglich, dass die Flüssigkeitskollektorenanordnung aus mehreren Rohrschleifen mit parallelen Längsabschnitten besteht, wobei sich mindestens die Längsabschnitte entlang der Wandung der Stollenkammer erstrecken und dort unter Bildung eines vorzugsweise begehbaren Tunnels mit Beton verkleidet sind.If the tunnel has to be or can be walked on, it is also possible for the liquid collector arrangement to consist of several pipe loops with parallel longitudinal sections, at least the longitudinal sections extending along the wall of the gallery and being clad with concrete to form a preferably accessible tunnel.

Beispielsweise Ausführungsformen des Erfindungsgegenstandes sind nachfolgend anhand der Zeichnung näher erläutert.For example, embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing.

  • Fig. 2 in schematischer Schnittdarstellung eine Ausführungsvariante der erfindungsgemässen Primärenergiequelle; und
  • Fig. 3 in einem Querschnitt, ausschnittsweise, eine weitere Ausführungsvariante der erfindungsgemässen Primärenergiequelle.

  • 2 shows a schematic sectional illustration of an embodiment variant of the primary energy source according to the invention; and
  • 3 in a cross section, in sections, a further embodiment variant of the primary energy source according to the invention.

Das betreffende Wärmepumpen-Heizsystem üblicher Bauart und von üblichem Verwendungszweck, beispielsweise zum Beheizen eines Wohnquartiers, ist hier gemäss Fig. 1 lediglich durch eine schematisch angedeutete Wärmepumpe 10 veranschaulicht mit der der Primärenergiekreis 11 des Wärmepumpen-Heizsystems über einen Wärmetauscher 12 in Wirkungsverbindung steht. Dieser Wärmetauscher 12 ist dabei über einen sogenannten Vorlauf 13 und über einen Rücklauf 14 mit einer Flüssigkeitskollektorenanordnung 1 des Primärenergiekreises 11 strömungsverbunden, wobei wenigstens eine Umwälzpumpe 15 beispielsweise im Vorlauf 13 die Wärmeträgerflüssigkeit im Kreis in Umlauf hält.The relevant heat pump heating system of conventional design and of normal use, for example for heating a residential area, is illustrated here according to FIG. 1 only by a schematically indicated heat pump 10 with which the primary energy circuit 11 of the heat pump heating system is operatively connected via a heat exchanger 12. This heat exchanger 12 is fluidly connected via a so-called flow 13 and a return 14 to a liquid collector arrangement 1 of the primary energy circuit 11, at least one circulation pump 15, for example in the flow 13, circulating the heat transfer fluid.

Soweit sind Wärmepumpen-Heizsysteme bekannt und bedürfen so keiner näheren Erläuterung.So far, heat pump heating systems are known and so do not require any further explanation.

Das vorliegende Problem besteht nun darin, Wärmepumpen-Heizsysteme der vorgenannten Art mit einer neuen Primärenergiequelle zu versehen.The problem now is to To provide heating systems of the aforementioned type with a new primary energy source.

Dies wird zunächst ganz allgemein erfindungsgemäss so gelöst, dass die der Wärmeaufnahme dienende Flüssigkeits- kollektorenanordnung 1 in einem Bergwerkstollen oder Höhlenteil angeordnet wird.This is initially solved in a very general way according to the invention in such a way that the liquid collector arrangement 1 for heat absorption is arranged in a mine gallery or cave part.

Die Kollektorenanordnung 1 kann dabei aus mehreren Rohrwindungen bestehen (Fig. 1), die in einen Grundwassersee oder in eine durch Schotten 16 geschlossene und gegebenenfalls mit Grundwasser gefüllte Stollenkammer 2 eintauchen.The collector arrangement 1 can consist of several pipe windings (FIG. 1) which are immersed in a groundwater lake or in a gallery 2 closed by bulkheads 16 and possibly filled with groundwater.

Solche Kammern 2 sind in der Regel in stillgelegten Bergwerken oder in nicht begangenen Höhlen relativ leicht herstellbar, müssen aber gegebenenfalls ausbetoniert werden, um ein Versickern des gestauten Grundwassers zu verhindern. Das Zuführen der Vorlauf- bzw. Rücklaufrohrleitung erfolgt dabei vorzugsweise durch vertikale Sondierungsbohrungen durch die Erddecke hindurch. Die benötigte Leistungsfähigkeit der Umwälzpumpe 15 richtet sich dann neben der gewünschten Fördermenge nach der Förderhöhe im Vorlauf.Such chambers 2 are generally relatively easy to manufacture in disused mines or in caves that are not used, but may need to be concreted in order to prevent the backed-up groundwater from seeping away. The supply or return pipeline is preferably fed through vertical probing holes through the ground cover. The required performance of the circulation pump 15 then depends on the desired delivery rate and the delivery head in the flow.

Eine weitere Ausführungsform der erfindungsgemässen Primärenergiequelle ist der Fig. 2 entnehmbar, wonach die Flüssigkeitskollektorenanordnung l' durch eine durch Schotten 16 geschlossene, mit Grundwasser gefüllte Stollenkammer 2 gebildet wird, in welcher Stollenkammer 2 Zwischenwände 3 das notwendige Strömungslabyrinth bilden.A further embodiment of the primary energy source according to the invention can be seen in FIG. 2, according to which the Liquid collector arrangement 1 'is formed by a tunnel chamber 2, which is closed by bulkheads 16 and is filled with groundwater, in which tunnel chamber 2 partition walls 3 form the necessary flow labyrinth.

Ferner ist es möglich, gemäss Fig. 3 die Flüssigkeits- kollektorenanordnung l" durch mehrere Rohrschleifen mit parallelen Längsabschnitten 4 zu bilden, wobei sich dann mindestens die Längsabschnitte 4 entlang der Wandung der Stollenkammer 2 erstrecken und dort unter Bildung eines vorzugsweise begehbaren Tunnels 5 mit Beton verkleidet sind.It is also possible, according to FIG. 3, to form the liquid collector arrangement 1 "by means of a plurality of pipe loops with parallel longitudinal sections 4, in which case at least the longitudinal sections 4 extend along the wall of the gallery chamber 2 and there form a preferably walkable tunnel 5 with concrete are disguised.

Durch diese vorbeschriebenen Massnahmen ist es somit erstmals möglich, die relativ hohen und konstanten Temperaturen in einem Bergwerkstollen oder in einer Höhle rationell, kostengünstig und mit hohem Wirkungsgrad als Primärenergiequelle für ein Wärmepumpen-Heizsystem zu nützen.These measures described above make it possible for the first time to use the relatively high and constant temperatures in a mine gallery or in a cave efficiently, cost-effectively and with high efficiency as a primary energy source for a heat pump heating system.

Selbstverständlich kann die erfindungsgemässe Primärenergiequelle in gleicher Weise zum Kühlen herangezogen werden. Ebenso ist der Anschluss anderer Verbraucher denkbar.Weiter können die Vorlauf- und Rücklaufrohre auswechselbar in einem fest im Stollen einbaubaren Mantelrohr eingesetzt sein, wobei ein Wassermantel im Ringspalt zwischen Mantelrohr und Innenrohr der Wärmeübertragung dient.Of course, the primary energy source according to the invention can be used for cooling in the same way. The connection of other consumers is also conceivable. Furthermore, the supply and return pipes can be exchangeably inserted in a jacket pipe that can be permanently installed in the gallery, a water jacket in the annular gap between the jacket pipe and the inner pipe being used for heat transfer.
