Abstract

The invention relates to the use of earth heat as a heat source for heat pumps. It serves the function of heat removal from the earth via a self-contained circuit, the absorber pipes being introduced vertically into the earth. The essential details of the invention are drawn in Fig. C. The advantages achieved with the invention are: construction is possible with a small area of ground almost in every case; no access with lorry or excavator is necessary - the ground only has to be accessible; problem-free implementation in already laid-out pieces of land - no visible installation parts; heat extraction from the earth in a protected and closed circuit - without removal or reintroduction of ground water; risk-free insertion into the earth, in particular in relation to imperviousness of the system; heat removal in a layer of the earth (to approx. 6 m depth) which is favourable in terms of energy - during the warm season heat continues to flow from solar radiation; the system can be repaired and can be extended subsequently with low outlay. <IMAGE>

Description

Erdreichwärme - Sammler als Wärmequelle für Wärmepumpen. Geothermal heat collector as a heat source for heat pumps.

PATENTBESCHREIBUNG Die Erfindung bezieht sich auf die Nutzung der Erdreichwärme als Wärmequelle für Wärmepumpen. Sie dient den Zweck der Wärmeentnahme aus dem Erdreich huber einen in sich geschlossenen Kreislauf. PATENT DESCRIPTION The invention relates to the use of the Geothermal energy as a heat source for heat pumps. It serves the purpose of extracting heat from the ground over a closed cycle.

Es ist bekannt, daß das Erdreich eine geeignete Wärmequelle für den Betrieb von Wärmepumpen ist. Die Wärmeentnahme wird nach dem Stand der Technik über zwei verschiedene Systeme praktiziert: 1. Es ist bekannt, daß über maanderförmig, waagrecht ins Erdreich verlegte Rohr- oder Schlauchechlangen warme entzogen werden kann.It is known that the ground is a suitable source of heat for the Operation of heat pumps is. The heat extraction is based on the state of the art two different systems are practiced: 1. It is known that over meandering, Warm pipes or hoses laid horizontally in the ground are withdrawn can.

2. Es ist bekannt, daß mit Tiefensonden, die aus aufeinandergeschraubten Eisenrohren bestehen und die von einem Punkt aus (Kellerraum, Grube) igelförmig tief ins Erdreich eingebracht werden, dem Erdreich Wärme entzogen werden kann.2. It is known that with depth probes, which are screwed together Iron pipes are made and those from one point (basement, pit) are hedgehog-shaped be introduced deep into the ground, heat can be extracted from the ground.

Diese bekannten Systeme weisen folgende Nachteile auf: o Sehr großer technischer Aufwand durch Abraum des Erdreichs, bz. beim Einbringen der Tiefensolzden.These known systems have the following disadvantages: Very large technical effort by overburdening the earth, or when bringing in the deep wood.

o Unsicherheit in der Ausführbarkeit (geologische Gutachten).o Uncertainty in the feasibility (geological reports).

o Irreparabilität bei evtl. auftretenden Schäden durch Korrosion oder Alterung.o Irreparability in the event of damage caused by corrosion or Aging.

o Hohe Herstellungskosten, Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen kostengünstigen und zweckdienlichen Erdreichwärme - Sammler zu schaffen.o High manufacturing costs. The object of the present invention is based on creating an inexpensive and useful geothermal heat collector.

Diese Aufgabe wurde erfindungsgemß dadurch gelöst, daß Stützrohre mit einer Lange von ca. 5 m und aufgeschweißter Rammspitze mehr oder minder senkrecht in das Erdreich eingebracht werden, in die Sammlerrohre aus einem Stück und gut wärmeleitendem Material eingeschoben werden. Diese Sammlerrohre enthalten die Zuleitung für den Wärmeträger in der Form eines bis fast auf das untere verschlossene Ende reichendes Rohres oder Schlauches. Der Wärmeträger wird somit beim Flißen nach oben an der Wand des Sammlerrohres erwärmt.This object has been achieved according to the invention in that support tubes with a length of approx. 5 m and a welded-on ram tip more or less vertical be placed in the ground, in the collector pipes made of one piece and well thermally conductive material are inserted. These header pipes contain the supply line for the heat transfer medium in the form of one end that is closed almost to the bottom reaching pipe or hose. The heat transfer medium is thus upwards when flowing heated on the wall of the collector pipe.

Im praktischen Fall werden mehrere dieser Erdreichwärme-Sammler gem-B der Erfindung möglichst in einer Reihe eingebracht und durch in einem Graben liegende Hauptstrange (Vor-und Rücklauf) parallel zueinander'angeschlossen.In the practical case, several of these geothermal heat collectors according to B the invention introduced as possible in a row and by lying in a trench Main lines (flow and return) are connected in parallel to one another.

Die Erfindung kann dahingehend weiter ausgestaltet werden, daß anstelle des Stützrohres eine Konstruktion mit größerem Durchmesser (z.B. Betonringe) ins Erdreich eingebracht wird, deren Inhalt als Medium zur Wärmespeicherung wirkt.The invention can be further developed to the effect that instead of of the support tube a construction with a larger diameter (e.g. concrete rings) Soil is brought in, the content of which acts as a medium for heat storage.

Die mit der Erfindung erzielbaren Vorteile sind: o Wärmeentzug ohne Entnahme und Wiedereinleitung von Grundwasser, in einem geschützten und geschlossenem Kreislauf.The advantages that can be achieved with the invention are: o heat extraction without Withdrawal and reintroduction of groundwater, in a protected and closed Cycle.

o Risikolose Einbringung ins Erdreich insbesondere in Bezug auf Dichtheit des Systems.o Risk-free installation in the ground, especially with regard to tightness of the system.

o Wärmeentnahme in einer energetisch günstigen Schicht des Erdreichs (bis ca. 6 m Tiefe): während der warmen Jahreszeiten fließt Wärme aus Sonneneinstrahlung nach.o Heat extraction in an energetically favorable layer of the ground (up to approx. 6 m depth): During the warm seasons, heat flows from solar radiation after.

o Eine Bauausführung ist fast in edlen Fall mit einer geringen Grundstücksfläche möglich. Es ist keine Zufahrt mit LKW oder Bagger.erforderlich, das gelände muß lediglich begehbar sein.o A construction work is almost in noble case with a small plot of land possible. No truck or excavator access is required, the site must only be accessible.

o Problemlose Ausführung in bereits angelegten Grundstücken; keine sichtbaren Anlagenteile.o Problem-free execution in already created properties; no visible system parts.

o Möglichkeit der Reparatur bei Leckagen und Möglichkeit des nachträglichen Einbringens weiterer Warme - Sammler.o Possibility of repairs in the event of leaks and the possibility of subsequent Bringing in additional heat collectors.

o Möglichkeit der weiteren Ausgestaltung des Systems zu einem mit Sonnenenergie beheizten Erdreich - Speicher.o Possibility of further designing the system into one with Solar energy heated ground storage.

o Kosten- und fertigungstechnisch günstige Herstellung durch Verwendung von Rohren.in einem Stück und in handelsüblichen Längen.o Production through use which is favorable in terms of cost and production technology of pipes. in one piece and in standard lengths.

In Fig. B ist ein Ausführungsbeispiel der vorliezenden Erfindung beschrieben.In Fig. B, an embodiment of the present invention is described.
