Description
Die Erfindung betrifft eine Anordn.ig zur Verbesserung derThe invention relates to an arrangement for improving the
Regenerierung des Wärmehaushaltes im Erdreich und zur Erhöhung der Leistung von Erdwärmekollektoren, insbes. bei Wärmepumpen und dergl.Regeneration of the heat balance in the ground and to increase the Performance of geothermal collectors, especially with heat pumps and the like.
Zur Nutzung der Erdwärme ist es bekannt, mittels sogenamter Erdwärmekollektoren, durch die Kältemittel geleitet werden, über Wärmepumpen dem Erdreich Wärme zu entziehen. Damit dieses über längere Zeiträume möglich ist, muß sich der Wärmehaushalt des Erdreiches immer wieder regenerieren können. Das geschieht in der Regel durch Grundwasserströmungen im Erdreich. Infolge der Intensivierung der Wasserwirtschaft und Begradigung von Wasserläufen usw. senkt sich der Grundwasserspiegel immer weiter ab, so daß die Erdwärmekollektoren, da bei zu trockenen Böden der Wärmeübergang außerordentlich schlecht ist, immer tiefer verlegt werden müßten, was aufwendig und teuer wäre und der Erfahrung, daß für eine zügige Regenerierung des Wasserhaushaltes im Boden eine Verlegetiefe der Erdwärmekollektoren in einer Tiefe von 80 bis 100 cm, bei der auch der Pflanzenbewuchs keine Störung erleidet, am ginstigsten. wäre, zuwider läuft.To use geothermal energy, it is known, by means of so-called geothermal collectors, through which refrigerants are conducted to extract heat from the ground via heat pumps. So that this is possible over longer periods of time, the heat balance of the Being able to regenerate the ground again and again. This usually happens through groundwater currents in the ground. As a result of the intensification of water management and straightening of Watercourses, etc., the water table continues to sink, so that the Geothermal collectors, as the heat transfer is extraordinary when the soil is too dry is bad, would have to be laid deeper and deeper, which would be laborious and expensive and the experience that for a rapid regeneration of the water balance in the soil a Laying depth of the geothermal collectors at a depth of 80 to 100 cm, which is also the case the vegetation is not disturbed, least of all. would run counter to.
Durch die Erfindung soll einmal die Aufgabe gelöst werden, die Regenerierung des Wasserhaushaltes im Boden zu verbessern und damit auch die Leistung der Erdwärmekollektoren zu verbessern.The invention is intended to solve the problem, the regeneration to improve the water balance in the soil and thus also the performance of the geothermal collectors to improve.
Zur Lösung dieser Aufgabe wird erfindungsgemäß bei einer Anordnung der eingangs genannten Art vorgeschlagen, dem Erdreich im Bereich der Erdwärmekollektoren gezielt Wasser von Regensammelflächen, wie Hausdächern und dergl. zuzuführen. Bei einer bevorzugten Ausführungsform der Erfindung sollen die Erdwärmekollektoren in Kiesschichten eingebettet sein, die über zwischen Vor- und Rücklauf der Erdwärmekollektoren angeordnete Dränrohre mit den Regenabläufen von Hausdächern und dergl. in Verbindung stehen-. Dabei sollendie Kiesschichten in Wärmepumpennähe bzw. in der Nähe der Hauswand eine größere Stärke aufweisen als in größerer Entfernung von der Wärmepumpe. Die größere Stärke der Schicht ist dabei vorteilhaft, damit das hier schneller aufgenommene Wasser die in der Nähe der Hauswand leicht auftretende Vereisung verhindert.To solve this problem, according to the invention in a arrangement proposed the type mentioned above, the ground in the field of geothermal collectors to supply water in a targeted manner from rain-collecting areas, such as house roofs and the like. at a preferred embodiment of the invention, the geothermal collectors in Layers of gravel are embedded, which is about between the flow and return of the geothermal collectors arranged drainage pipes with the rain drains from house roofs and the like. In connection stand-. The gravel layers should be near the heat pump or near the house wall have greater strength than at a greater distance from the heat pump. the greater thickness of the layer is advantageous, so that what is absorbed here faster Water that prevents freezing that can easily occur near the house wall.
Bei einer konkreten Ausführungsform der erfindungsgemäßen Anordnung können die Erdwärmekollektoren in Gräben verlegt sein, die eine Tiefe von 80 bis 100 cm, eine Breite von ca.In a specific embodiment of the arrangement according to the invention The geothermal collectors can be laid in trenches with a depth of 80 to 100 cm, a width of approx.
40 bis 60 cm und einen Abstand zueinander von ca. 1 m aufweisen und die Kiesschichten,in denen die Erdwärmekollekto-ren in den Gräben verlegt sind, eine Stärke von ca. 15 cm, in der Nähe der Hauswand auf ca. 40 cm ansteigend, aufweisen.40 to 60 cm and a distance of approx. 1 m from one another and the layers of gravel in which the geothermal collectors are laid in the trenches, have a thickness of approx. 15 cm, increasing to approx. 40 cm near the house wall.
An Hand der beiliegenden Zeichnung soll die Erfindung nachfolgend noch weiter erläutert werden. Auf der Zeichnung zeigen in schematischer Darstellung Fig. 1 einen Teilschnitt durch ein Haus mit Wärmepumpe und dazugehörigen Erdwärmekollektoren und Fig. 2 einen Querschnitt durch Gräben mit Wärmekollektoren und Dränrohren.On the basis of the accompanying drawing, the invention is intended below to be explained further. On the drawing show in a schematic representation Fig. 1 is a partial section through a house with a heat pump and associated Geothermal collectors and FIG. 2 shows a cross section through trenches with heat collectors and drainage pipes.
An der Wand 10 eines Hauses ist in Fig. 1 ein Regenablauf -12 dargestellt, durch den das vom D-ach 11 ablaufende Regen- oder auch Schmutzwasser bei Schneefall abgeleitet wird. Im darge-.On the wall 10 of a house, a rain drain -12 is shown in Fig. 1, due to the rain or dirty water running off the D-ach 11 when it is snowing is derived. In the presented.
stellten Beispiel endet der Regenablauf 12 in einer Kiesschicht 15 in der Erdwärmekollektoren 14 verlegt sind, die mit einer Wärmepumpe 13 in Verbindung stehen.In the illustrated example, the rain runoff 12 ends in a layer of gravel 15 are laid in the geothermal collectors 14, which are connected to a heat pump 13 stand.
Fig. 2 läßt die Gräben 17 im Erdreich 16 erkennen, an deren Grund die Erdwärmekollektoren 14 in der Kiesschicht 15 verlegt sind. Bei diesem Ausführungsbeispiel sind noch Dränrohre 18 zu erkennen, die mit dem Wasserablauf 12 von Dach 11 verbunden sind und zur schnellen Weiterleitung des anfallenden Wassers in den gesammten Bereich der Erdwärmekollektoren dienen.Fig. 2 shows the trenches 17 in the ground 16, at their bottom the geothermal collectors 14 are laid in the gravel layer 15. In this embodiment drainage pipes 18 can still be seen, which are connected to the water drainage 12 from roof 11 are and for the fast forwarding of the accumulating water in the whole area the geothermal collectors are used.
Durch die Erfindung wird die Möglichkeit geschaffen, auch bei tiefliegendem Grundwasserstand eine relativ flache Anordnung der Erdwärmekollekto en in der Erde mit allen damit verbundenen Vorteilen vorzusehen. Insbesondere in regenreichen Gegenden erfolgt damit eine außerordentlich schnelle Regenerierung des Erdreiches, wobei sich noch zusätzlich vorteilhaft auswirkt, daß die Dachflächen durch Sonnenstrahlung aufgeheizt werden und durch das Regenwasser ein Teil dieser Wärme mit in das Erdreich eingebracht wird. Das wirkt sich besonders vorteilhaft bei Schmelzwasser nach Schneefällen aus. Statt der Dachflächen können auch andere Flächen zur Erzielung der gewünschten Wirkungen herangezogen werden, sofern auf ihnen Regen gesammelt und durch Abläufe abgeleitet wird.The invention creates the possibility, even with deep lying Groundwater level is a relatively flat arrangement of geothermal collectors in the earth to be provided with all the associated advantages. Especially in rainy areas This means that the soil is regenerated extremely quickly, with has an additional beneficial effect that the roof surfaces through solar radiation are heated and through the rainwater some of this heat enters the ground is introduced. This is particularly beneficial Meltwater after snowfall. Instead of the roof surfaces, other surfaces can also be used to achieve the desired effects can be used, provided that rain is collected on them and is derived through processes.
