Abstract
Description
Formanpassungsfähige Absorberzelle mit Wärmespeicher für Sonnenenergie in kompakter Bauweise.Adaptable absorber cell with heat storage for solar energy in a compact design.
Die Erfindung betrifft eine Absorberzelle mit Wärmespeicher, die sich an unterschiedliche bauliche Formen anpassen läßt.The invention relates to an absorber cell with heat storage, which can be adapted to different structural forms.
Absorberzellen für Warmwassererwärmung sind besonders für Touristenhotels in wärmeren Ländern interessant. Da diese Hotels oft sehr eigenwillige Fassaden haben, würde das äußere Bild durch die bisher bekannten Formen der Absorberzellen stark gestört.Absorber cells for warm water heating are especially useful for tourist hotels interesting in warmer countries. Because these hotels often have very idiosyncratic facades would have the external image through the previously known shapes of the absorber cells severely disturbed.
Die Absorberzellen werden bisher als starre Elemente gebaut, die mit einem Wärmespeicher durch Schläuche verbunden sind.The absorber cells are so far built as rigid elements with a heat accumulator are connected by hoses.
Solche Ausführungen sind sehr teuer und beeinträchtigen das architektonische Bild oft derart, daß auf ihre Anwendung oft verzichtet wird.Such designs are very expensive and affect the architectural Image often in such a way that it is often not used.
Dieser Erfindung liegt di'e Aufgabe zugrunde, eine formanpassungsfähige Absorberzelle mit Wärmespeicher zu erhalten, die sich an jede architektonische,Form anpaßt und deren Einsatz durch die geringen Herstellungskosten sehr wirtschaftlich ist.The object of this invention is to provide a conformable Get absorber cell with heat storage that adapts to any architectural shape adapts and their use is very economical due to the low manufacturing costs is.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Absorberkörper und Wärmespeicher aus Kunststoffolien hergestellt werden, die an entsprechenden Stellen so, verschweißt sind, daß sich eine großflächige, formbestä,ndige an den Untergrund anpassungsfähige Einheit ergibt. Dieses wird dadurch erreicht, daß mindestens 2 Folien mit Längsschweißnähten oder Schweißpunkten so zusammen geschweißt werden, daß sich eine stabile Form gegen den Wasserdruck ergibt, und die Schweißstellen die bevorzugten Knickstellen zur Anpassung an den Untergrund bilden. Die durch diese Erfindung erzielten Vorteile bestehen darin, daß es hiermit möglich wird, Absorberzellen mit Speicher zur Gewinnung der Sonnenenergie durch die einfache und kompakte Bauweise an beliebig architektonischen Bauformen unauffällig anzupassen und die Kosten der Herstellung erheblich zu senken.The object is achieved according to the invention in that the absorber body and heat accumulators are made of plastic films, which are attached to corresponding Places are welded in such a way that there is a large area, dimensionally stable to the Subsurface adaptable unit results. This is achieved in that at least 2 foils with longitudinal weld seams or weld spots like this together be welded so that there is a stable shape against the water pressure, and the welds are the preferred kinks to adapt to the subsurface form. The advantages achieved by this invention are that it is hereby becomes possible, absorber cells with storage for the production of solar energy through the simple and compact design is inconspicuous on any architectural design adapt and reduce the cost of manufacturing significantly.
In der beiliegenden Zeichnung sind einige Ausführungsbeispiele dargestellt.Some exemplary embodiments are shown in the accompanying drawing.
Das in Fig. 1 gezeigte-Beispiel besteht aus der Absorberzelle (1) und dem Speicher (4). Die Absorberzelle (1) wird durch die Schweißnähte (2) in die Kanäle (3) unterteilt.The example shown in Fig. 1 consists of the absorber cell (1) and the memory (4). The absorber cell (1) is through the welds (2) in the Channels (3) divided.
Die Anordnung der Kanäle (3) ist so, daß die aus dem SDeicher (4) in den Absorberkörper (1) einfließende Flüssigkeit dem Speicher von unten entnonunen wird (1l). Nachdem die Flüssigkeit die Absorbtionszelle durchlaufen hat, infolge natürlicher Konvektion oder durch Zwangsumlauf, tritt die erwärmte Flüssigkeit bei (10! oben in den Wärmespeicher (4) ein. Einlaß (5), Enthahme- (6) und Ablaßstutzen (7) werden ebenfalls durch entsprechende Schweißnähte hergestellt.The arrangement of the channels (3) is such that the data from the SDeicher (4) Liquid flowing into the absorber body (1) is taken from the reservoir from below becomes (1l). After the liquid has passed through the absorption cell, as a result natural convection or forced circulation, the heated liquid joins (10! At the top of the heat accumulator (4). Inlet (5), extraction (6) and drainage connections (7) are also produced using appropriate welds.
Die Fig. 2 zeigt eine ?sorberzelle im Schnitt, die an die Form einer Wand mit senkrecht verlaufenden Knickstellen angepaßt ist. In diesem Fall bildet die Wand die Isolierung nach hinten. Ansonsten kann die Isolierung nach hinten durch eine zusätzliche Folie oder übliche Isolierstoffe vorgenommen werden.Fig. 2 shows a sorber cell in section, which is in the shape of a Wall is adapted with perpendicular kinks. In this case it forms the wall the insulation to the rear. Otherwise the insulation can slip through to the rear an additional film or customary insulating materials can be made.
An der Vorderseite, index die Sonnenstrahlung einfälLt, wird die Absorberzelle (8) durch eine lichtdurehlässige Folie t9;1 und die damit eingeschlossene Luft isoliert.At the front, where the solar radiation falls, is the absorber cell (8) insulated by a light-permeable film t9; 1 and the air enclosed with it.
Die Absorberzelle selbst kann aus zwei Folien hergestellt werden, bei denendie vordere die Sonnenstrahlen absorbiert, oder aus einer lichtdurchlässigen vorderen Folie (14) und einer lichtabsorbierenden hinteren Folie (15).The absorber cell itself can be made from two foils, in which the front one absorbs the sun's rays, or from a translucent one front film (14) and a light-absorbing rear film (15).
Letzteres hat den Vorteil, daß die Umwandlung der Sonnenstrahlung in Wärme in der Absorberzelle, auf der flüssigkeitsbenetzten Fläche der hinteren Folie (15) erfolgt. Dadurch kann die Wärme direkt an die durchströmende Flüssigkeit abgegeben werden. Damit wird eine erhebliche Verbesserung des Wirkungsgrades erreicht, da die Temperatur der Wand der Absorberzelle nicht höher als die der Flüssigkeit.The latter has the advantage that the conversion of solar radiation in heat in the absorber cell, on the liquid-wetted surface of the rear Foil (15) takes place. This allows the heat to pass directly to the flowing liquid be delivered. This achieves a considerable improvement in the degree of efficiency, because the temperature of the wall of the absorber cell is not higher than that of the liquid.

Die Schweipnähte können auch unterbrochen angeordnet sein oder durch Schweißpunkte ersetzt werden.The weld seams can also be arranged interrupted or through Weld points are replaced.
