Description

Die Erfindung betrifft Dach- und Fassaden-Leichtbauelemente.The invention relates to roof and facade lightweight construction elements.

Durch die Druckschrift DE 198 51 230 A1 ist ein Solar-Dach- und -Wandelement aus Metall bekannt. Auf der Oberseite einer in Längsrichtung profilierten Blechtafel ist die lichtdurchlässige Abdeckung eines Solarkollektors und/oder ein Photovoltaik-Solarmodul kraftschlüssig befestigt. Die in Längsrichtung verlaufenden Kanäle können als Leitungen für flüssige oder gasförmige Medien zum Transport von Sonnenwärme genutzt werden. In den Kanälen können auch wärmeisolierende Materialien eingebracht sein. Zur Nutzung dieser Kanäle müssen diese für das jeweilige Medium dicht sein. Das ist auch bei der Kombination mehrerer Elemente zu gewährleisten. Weiterhin ist eine durchgehende Wärmeisolation bei diesem Element nicht vorhanden.Through the publication DE 198 51 230 A1 is a solar roof and wall element made of metal known. The translucent cover of a solar collector and / or a photovoltaic solar module is frictionally secured on top of a profiled metal sheet profiled in the longitudinal direction. The longitudinal channels may be used as conduits for liquid or gaseous media for transporting solar heat. In the channels and heat-insulating materials can be introduced. To use these channels, they must be tight for the respective medium. This is also to be ensured when combining several elements. Furthermore, a continuous heat insulation in this element does not exist.

Die Druckschrift DE 20 2006 018 592 U1 beinhaltet ein elektrothermisches Solarmodul. Dazu sind auf einer Grundplatte Photovoltaikelemente angeordnet. Die Grundplatte umgibt weiterhin ein Rahmen aus einem U-förmigen Profil, dessen offene Seite in Richtung Sonne weist und mit einer lichtdurchlässigen Transparenzplatte bedeckt ist. Im Profil strömende Flüssigkeit wird durch die Sonneneinstrahlung erwärmt. Die Funktionen sind in der Fläche voneinander getrennt. Insbesondere die mittig angeordneten Photovoltaikelemente werden nicht gekühlt. Einrichtungen für eine Wärmeisolation sind nicht vorgesehen.The publication DE 20 2006 018 592 U1 includes an electrothermal solar module. For this purpose, photovoltaic elements are arranged on a base plate. The base plate further surrounds a frame of a U-shaped profile, the open side faces the sun and is covered with a translucent transparency plate. Liquid flowing in the profile is heated by the solar radiation. The functions are separated in the surface. In particular, the centrally arranged photovoltaic elements are not cooled. Facilities for thermal insulation are not provided.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, energiewandelnde kompakte Dach- und Fassadenelemente einfach zu schaffen.The indicated in claim 1 invention has for its object to easily create energy-converting compact roof and facade elements.

Diese Aufgabe wird mit den im Patentanspruch 1 aufgeführten Merkmalen gelöst.This object is achieved with the features listed in claim 1.

Die Dach- und Fassaden-Leichtbauelemente zeichnen sich sowohl durch ihre Kompaktheit als auch ihrer Funktionalität aus.The roof and facade lightweight construction elements are characterized by their compactness as well as their functionality.

Dazu besteht ein Dach- und Fassaden-Leichtbauelement aus einer Tragplatte mit wenigstens einer Konstruktion zur Erhöhung der Biegesteifigkeit, einem Kern aus einem geschäumten Kunststoff als wärmeisolierendes Material auf der Tragplatte und mindestens einem Photovoltaik-Element auf dem Kern. Weiterhin weist das Element mindestens eine Leitung für ein Kühlmedium zur Kühlung des Photovoltaik-Elements im Kern auf.For this purpose, there is a lightweight roof and facade element of a support plate having at least one construction for increasing the flexural rigidity, a core of a foamed plastic as a heat-insulating material on the support plate and at least one photovoltaic element on the core. Furthermore, the element has at least one line for a cooling medium for cooling the photovoltaic element in the core.

Das Dach- und Fassaden-Leichtbauelement ist ein universell einsetzbares Bauhüllenelement, welches die herkömmlichen Funktionen von Dach und Fassade eines Gebäudes, wie Raumabschluss, statische Funktionen, Wetterschutz, Wärmedämmung, Lärmschutz, Verschattung und Sichtschutz mit einer bestmöglichen Nutzung der Solarenergie verbindet. Dazu bildet das Photovoltaik-Element den äußeren Abschluss des Dach- und Fassaden-Leichtbauelements.The roof and facade lightweight construction element is a universally applicable building shell element, which combines the conventional functions of roof and facade of a building, such as room closure, static functions, weather protection, thermal insulation, noise protection, shading and privacy with the best possible use of solar energy. For this purpose, the photovoltaic element forms the outer end of the roof and facade lightweight element.

Photovoltaik-Elemente sind als Dünnschicht- und Dickschicht-Solarzellen bekannt. Mehrere miteinander verbundene Solarzellen bilden ein Solarmodul. Die Solarzellen bestehen im Wesentlichen aus Halbleitermaterialien insbesondere Silizium. Der Wirkungsgrad ist insbesondere von der Halbleitertechnologie abhängig. Bei Photovoltaik-Elementen ist zu beachten, dass der Wirkungsgrad der Elektroenergieerzeugung mit steigender Temperatur rückläufig ist. Das ist insbesondere im Sommer nachteilig, wobei sich die Photovoltaik-Elemente auf über 70°C aufheizen. Zur Kühlung des Photovoltaik-Elements besitzt das Dach- und Fassaden-Leichtbauelement mindestens eine Leitung für ein Kühlmedium. Bei der Kühlung wird das Kühlmedium erwärmt, so dass das Dach- und Fassaden-Leichtbauelement auch zur Solarthermie einsetzbar ist. Das erwärmte Kühlmedium wird dabei insbesondere zur Erwärmung von Wasser genutzt, das sowohl als Trink- als auch Brauchwasser einsetzbar ist. Das betrifft die Warmwasseraufbereitung und die Heizung jeweils einzeln oder in Kombination.Photovoltaic elements are known as thin-film and thick-film solar cells. Several interconnected solar cells form a solar module. The solar cells consist essentially of semiconductor materials, in particular silicon. The efficiency depends in particular on the semiconductor technology. For photovoltaic elements, it should be noted that the efficiency of electric power generation decreases with increasing temperature. This is particularly disadvantageous in the summer, with the photovoltaic elements heat up to over 70 ° C. For cooling the photovoltaic element, the lightweight roof and facade element has at least one line for a cooling medium. When cooling, the cooling medium is heated, so that the roof and facade lightweight element is also used for solar thermal. The heated cooling medium is used in particular for heating water, which can be used both as drinking and service water. This concerns the hot water treatment and the heating each individually or in combination.

Damit vereinigt das Dach- und Fassaden-Leichtbauelement sowohl das Prinzip der Photovoltaik als auch der Solarthermie in sich. Neben der Erwärmung des Kühlmediums wird gleichzeitig die elektrische Energieausbeute gesteigert.Thus, the roof and facade lightweight element combines both the principle of photovoltaics and solar thermal in itself. In addition to the heating of the cooling medium, the electrical energy yield is increased at the same time.

Die Nutzung beider Energiekomponenten nach dem Prinzip eines PVT(Photovoltaik und Solarthermie)-Kollektors führt im Zusammenhang mit den vorhandenen solar nutzbaren Gebäudeflächen zu einer maximalen Ausbeute an einer klimaschonenden Energiegewinnung.The use of both energy components in accordance with the principle of a PVT (photovoltaic and solar thermal) collector in conjunction with the existing solar usable building surfaces leads to a maximum yield of climate-friendly energy production.

Ein weiterer Vorteil ist durch den Kern aus einem geschäumten Kunststoff als wärmeisolierendes Material vorhanden. Wärmeisolierende Materialien wirken in der Regel vorteilhafterweise auch schalldämmend, so dass das Dach- und Fassaden-Leichtbauelement gleichzeitig sowohl der Wärmeisolation als auch der Schalldämmung dient.Another advantage is provided by the core of a foamed plastic as a heat insulating material. As a rule, heat-insulating materials also have a sound-insulating effect, so that the lightweight roof and façade element simultaneously serves both the heat insulation and the sound insulation.

Die Tragplatte gewährleistet vorteilhafterweise die Stabilität des Dach- und Fassaden-Leichtbauelements. Weiterhin wird eine hohe Tragfähigkeit durch den Sandwichaufbau über die feste Verbindung der Tragplatte mit dem Photovoltaik-Element mittels des geschäumten Kunststoffes erreicht.The support plate advantageously ensures the stability of the roof and facade lightweight element. Furthermore, a high load capacity is achieved by the sandwich structure on the solid compound of the support plate with the photovoltaic element by means of the foamed plastic.

Im Wesentlichen besteht damit ein Dach- und Fassaden-Leichtbauelement aus der Tragplatte, dem Kern und dem Photovoltaik-Element in einer Sandwichbauweise. Durch ein Aufbringen des Kerns auf die Tragplatte, wobei die Leitungen gleichzeitig eingebettet werden, und des Photovoltaik-Elements ist das Dach- und Fassaden-Leichtbauelement ökonomisch günstig realisierbar. Essentially, there is a roof and facade lightweight element of the support plate, the core and the photovoltaic element in a sandwich construction. By applying the core to the support plate, wherein the lines are embedded at the same time, and the photovoltaic element, the roof and facade lightweight construction element is economically feasible.

Die Dach- und Fassaden-Leichtbauelemente lassen sich leicht großflächig anordnen, so dass vorteilhafterweise wenigstens bereichsweise Fassaden und/oder Dächer mit diesen Dach- und Fassaden-Leichtbauelement versehen werden können.The roof and facade lightweight elements can be easily arranged over a large area, so that advantageously at least partially facades and / or roofs can be provided with these roof and facade lightweight element.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 9 angegeben.Advantageous embodiments of the invention are specified in the claims 2 to 9.

Die Tragplatte besitzt nach der Weiterbildung des Patentanspruchs 2 im Querschnitt eine Wellenform. Günstigerweise ist das eine Trapezform. Dadurch ist eine höhere Biegesteifigkeit im Gegensatz zu einer ebenen Tragplatte vorhanden.The support plate has according to the embodiment of claim 2 in cross section a waveform. Conveniently, this is a trapezoidal shape. As a result, a higher flexural rigidity in contrast to a flat support plate is present.

Der Kern überragt nach der Weiterbildung des Patentanspruchs 3 die Tragplatte. Damit ist insbesondere bei einer Tragplatte in Trapezform gewährleistet, dass sich zwischen Tragplatte und Photovoltaik-Element das wärmeisolierende Material als Kern befindet.The core dominates after the development of claim 3, the support plate. This ensures, in particular in the case of a carrier plate in trapezoidal shape, that the heat-insulating material is located as a core between the carrier plate and the photovoltaic element.

Das Photovoltaik-Element ist nach der Weiterbildung des Patentanspruchs 4 ein Solarmodul. Dabei sind bekannterweise mehrere Photovoltaik-Elemente elektrisch leitend miteinander verbunden.The photovoltaic element is according to the embodiment of claim 4, a solar module. As is known, a plurality of photovoltaic elements are electrically conductively connected to one another.

Die Tragplatte ist günstigerweise nach der Weiterbildung des Patentanspruchs 5 ein Metallblech. Eine derartige Tragplatte ist einfach und ökonomisch günstig realisierbar.The support plate is favorably according to the embodiment of claim 5, a metal sheet. Such a support plate is simple and economically feasible.

Mehrere Rohre sind nach der Weiterbildung des Patentanspruchs 6 als Leitungen beabstandet und parallel zueinander angeordnet. Damit wird eine optimale Kühlung des Photovoltaik-Elements sichergestellt.Several tubes are spaced according to the embodiment of claim 6 as lines and arranged parallel to each other. This ensures optimum cooling of the photovoltaic element.

Die Rohre benachbarter Dach- und Fassadenelemente sind in Fortführung nach der Weiterbildung des Patentanspruchs 7 mittels Press-, Schraub-, Steck- oder Klebverbindungen miteinander verbunden. Damit lassen sich Dach- und Fassadenelemente einfach montieren und dabei die Rohre für das Kühlmedium leicht miteinander verbinden.The pipes of adjacent roof and facade elements are connected to each other in continuation of the embodiment of claim 7 by means of press, screw, plug or adhesive joints. This makes it easy to install roof and façade elements, while easily connecting the tubes for the cooling medium.

Die Rohre liegen nach der Weiterbildung des Patentanspruchs 8 als Leitungen am Solarmodul an. Damit wird ein guter Wärmeübergang vom Solarmodul zur Leitung und nachfolgend zum Kühlmedium gewährleistet. Die Rohre besitzen dazu einen kreisförmigen, ovalen oder einen mehreckigen Querschnitt auf. Insbesondere mit einem mehreckigen Querschnitt sind flächige Wärmeübergänge vorhanden.The tubes are according to the embodiment of claim 8 as lines on the solar module. This ensures good heat transfer from the solar module to the line and subsequently to the cooling medium. The tubes have for this purpose a circular, oval or polygonal cross section. In particular, with a polygonal cross-section, surface heat transfers are present.

Die Rohre bestehen nach der Weiterbildung des Patentanspruchs 9 vorteilhafterweise aus einem Metall oder einem Kunststoff.The tubes are made according to the embodiment of claim 9 advantageously made of a metal or plastic.
