Abstract

A solar energy collector, esp. for mounting on roofs, comprises two flexible plastics foil sheets sealed together to form between them a series of parallel ducts through which the heat transporting liquid flows. The ducting system is designed for forced guidance of the liquid from inlet to outlet points. At least the sheet facing towards the sun is resistant to ultraviolet radiation. It is pref. also adsorbent of solar radiation. Alternatively, the sheet towards the sun is transparent and the other sheet absorbs solar radiation. The solar collector is intended particularly for small users and is economical to construct.

Description

Sonnenenergiekollektor Solar energy collector

Die Erfindung betrifft einen Sonnenenergiekollektor, der auf Dächern oder anderen sonnenbestrahlten Flächen anbringbar ist und bei dem ein flüssiges Wärmetransportmedium durch geformte, parallel zueinander verlaufende Kanäle geführt wird.The invention relates to a solar energy collector on roofs or other sun-exposed surfaces can be attached and in which a liquid Heat transport medium passed through shaped channels running parallel to one another will.

Zur Ausnutzung von Solarwärme sind bereits zahlreiche Kollektoren bekannt, z.B. einfach über die Dachfläche gelegte, flüssigkeitsdurchströmte, flache Platten aus Blech, im Rahmen gefaßte, hinter Ein- oder Mehrscheibenglas gelegte, flüssigkeitsdurchströmte Kollektorfiatten und hinter die Dachhaut gelegte wasserdurchströmte Wärmesammelsysteme, wie Rohrnetze, -gitter und dergleichen. Bei all diesen Anordnungen ist die- Nutzung von Sonnenenergie für Heiz- oder Warmwasseraufbereitungszwecke mit großem technischem und materiellem Aufwand verbunden, der sich insbesondere für die Energieversorgung von kleineren Verbraucherstellen nicht rentiert. Dies gilt insbesondere für die Montage der Anlagen sowie deren Wartung und für Arbeiten, die zur Herstellung von für die Rohrführung oder Anbringung erforderlichen Teile notwendig sind. Des öfteren müssen zur Installation auch bauliche Veränderungen durchgeführt werden.There are already numerous collectors for utilizing solar heat known, e.g. simply laid over the roof surface, through which liquid flows, flat ones Plates made of sheet metal, framed, placed behind single or multi-pane glass, Collector slats through which liquid flows and those which are placed behind the roof cladding Heat collection systems such as pipe networks, grids and the like. With all these arrangements is the use of solar energy for heating or hot water purposes associated with great technical and material effort, in particular not for the energy supply of smaller consumer locations pays off. This applies in particular to the assembly of the systems as well as their maintenance and for work the parts required for piping or installation are necessary. Often structural changes also have to be made for the installation be performed.

Einmal angebracht ist die Demontage umständlich, ihr Transport aufgrund der sperrigen Form sowie des Gewichts nicht unproblematisch.Once attached, dismantling is cumbersome due to its transport the bulky shape and the weight are not without problems.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, einen Sonnenenergiekollektor zu schaffen, der die vorgenannten Nachteile nicht aufweist und die Nutzung der Solarwärme ohne großen technischen Aufwand auch für kleine Energieverbraucherstellen ermöglicht. Darüberhinaus sollte der Kollektor materialbedingt wirtschaftlich herstellbar sein.The present invention is based on the object of a solar energy collector to create that does not have the aforementioned disadvantages and the use of solar heat made possible without great technical effort even for small energy consuming points. In addition, the collector should be economical to manufacture due to the material used.

Es hat sich nun gezeigt, daß sich diese Aufgabe mit einem Sonnenenergiekollektor der eingangs genannten Art lösen läßt, wenn dieser aus mindestens zwei aufeinander geschweißten, flexiblen Kunststoffolien besteht, wobei durch die Schweißung ein Kanalsystem für die Zwangsführung des Wärmetransportmediums zwischen einer Eintritts- und einer Austrittsöffnung entsteht und wenn zumindest die von der Sonne zuerst bestrahlte Folie beständig gegen UV-Strahlung ist. Weitere Ausführungen des erfindungsgemäßen Kollektors sind in den Unteransprüchen 2 bis 7 beschrieben.It has now been shown that this task can be achieved with a solar energy collector the aforementioned type can be solved if this consists of at least two on top of each other welded, flexible plastic films, whereby a Channel system for the forced guidance of the heat transport medium between an inlet and an exit opening arises and if at least that from the sun first irradiated film is resistant to UV radiation. Further embodiments of the invention Collectors are described in the dependent claims 2 to 7.

Die durch die vorliegende Erfindung erzielten Vorteile sind im wesentlichen darin zu sehen, daß Kunststoffolien als in Großserienfertigung hergestellte Materialien eine wirtschaftliche Realisierung ermöglichen. Darüberhinaus sind sie wartungsfrei und zum Transport und Lagerung zusammenrollbar. Der erfindungsgemäße Flachkollektor kann ohne großen Aufwand auch auf geringfügig unebene Flächen, z.B.The advantages achieved by the present invention are substantial to see that plastic films as mass-produced materials enable an economical realization. Furthermore are they are maintenance-free and can be rolled up for transport and storage. The inventive Flat-plate collectors can also be used on slightly uneven surfaces, e.g.

im Garten, verlegt bzw. ausgelegt werden. Aufgrund seines geringen Gewichts und seiner hohen mechanischen Stabilität kann der Kollektor z.B. für die solare Schwimmbadbeheizung für den Sommerbetrieb installiert werden. Ferner ist eine Anbringung auf oder an Wohnwagen zum Zwecke der Warmwasseraufbereitung möglich. Da aus demselben Folienmaterial auch Dacheindeckungen für Flachdächer hergestellt werden, kann der erfindungsgemäße Kollektor direkt in die Dachhaut integriert werden.in the garden, laid or laid out. Because of its low Weight and its high mechanical stability, the collector can be used e.g. for the solar swimming pool heating can be installed for summer operation. Furthermore is Can be attached to or on caravans for the purpose of heating water. Since roof coverings for flat roofs are also made from the same film material the collector according to the invention can be integrated directly into the roof skin.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.In the following, the invention will be described on the basis of only one embodiment Illustrative drawings explained in more detail.

Figur 1 a bis c im Querschnitt drei Ausführungsformen des erfindungsgemäßen Kollektors und Figur 2 in Draufsicht den erfindungsgemäßen Kollektor.Figure 1 a to c in cross section three embodiments of the invention Collector and Figure 2 in plan view of the collector according to the invention.

In der in Figur 1 a gezeigten Ausführungsform wird eine Kunststoffolie 1, die gleichzeitig die Auflagefläche des Kollektors ist, so mit einer W-beständigen Folie 2 verschweißt, daß sich ein Kanalsystem 3 für den Wärmeträger bildet. Die UV-beständige Folie 2 kann transparent oder auch dunkel eingefärbt sein. Wenn die UV-beständige Folie 2 transparent ist, so ist zweckmäßigerweise die Folie 1 absorbierend für Sonnenstrahlen, hierfür z.B. dunkel bis schwarz eingefärbt. Die transparente Folie ergibt ferner einen Treibhauseffekt.In the embodiment shown in Figure 1 a, a plastic film 1, which is also the contact surface of the collector, so with a W-resistant Foil 2 is welded so that a channel system 3 is formed for the heat transfer medium. the UV-resistant film 2 can be transparent or also colored dark. If the UV-resistant film 2 is transparent, the film 1 is expediently absorbent for sun rays, e.g. colored dark to black. The transparent one Foil also has a greenhouse effect.

Zur Bildung des Kanalsystems 3 können beide Kunststofffolien 1 und 2 mit einer dritten Kunststoffolie 4 verschweißt werden, wie es in Figur 1 b gezeigt ist. Zum Zwecke der Verhinderung des Abflusses von Wärme nach unten kann ferner eine wärmegedämmte Unterlage 5 vorgesehen sein.To form the channel system 3, both plastic films 1 and 2 are welded to a third plastic film 4, as shown in Figure 1b is. For the purpose of preventing the outflow of heat downward can also a thermally insulated base 5 can be provided.

Diese Ausführungsform wird in Figur 1 c dargestellt.This embodiment is shown in Figure 1c.

Aus Figur 2 geht hervor, daß durch Verschweißung von beiden Folien ein durchgehendes Kanalsystem mit parallel zueinander verlaufenden Kanälen 3 entsteht. Vorzugsweise sind die Abstände zwischen den einzelnen Kanälen an der Eintrittsseite 6 des Wärmetransportmediums enger als an der Austrittsseite 7, um eine gleichmäßige Durchströmung, d.h. eine gleichmäßige Nutzung der gesamten Fläche zu gewährleisten. Die Strömung des Wärmetransportmediums kann zusätzlich durch im Kanalsystem angebrachte Hindernisse verlangsamt werden.From Figure 2 it can be seen that by welding the two films a continuous channel system with channels 3 running parallel to one another is created. The distances between the individual channels are preferably on the inlet side 6 of the heat transport medium narrower than on the outlet side 7 in order to achieve a uniform Through-flow, i.e. to ensure that the entire surface is used evenly. The flow of the heat transport medium can also be carried out through the duct system Obstacles are slowed down.
