Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Die Erfindung wird im Folgenden anhand der Figur, die in vereinfachter Darstellung und im Schnitt ein Photovoltaikmodul gemäß der Erfindung wiedergibt, näher erläutert.further developments The invention are the subject of the dependent claims. The invention is in Below with reference to the figure, in a simplified representation and shows in section a photovoltaic module according to the invention, explained in more detail.

Durch die luftdichte Ausführung der vorgehängten hinterlüfteten Photovoltaikfassade kann die, zwischen der Außenwand des Bauwerkes (1) und dem Photovoltaikmodul (2), befindliche Luftschicht (7) festgehalten werden, wodurch die Funktion einer Wärmedämmung übernommen wird. Die in der festgehaltenen Luftschicht (7) gespeicherte Wärmeenergie wird aufgrund der guten isolierenden Eigenschaften der Photovoltaikmodule (2) nur langsam nach Außen abgegeben.Due to the airtight design of the ventilated photovoltaic façade, which can be ventilated, between the outer wall of the building ( 1 ) and the photovoltaic module ( 2 ), located air layer ( 7 ), whereby the function of thermal insulation is taken over. The in the arrested air layer ( 7 ) stored heat energy is due to the good insulating properties of the photovoltaic modules ( 2 ) are released slowly to the outside.

Die Luftdichtheit des Systems wird dadurch erreicht, daß an allen Anschlußpunkten des Systems zwischen Außenwand des Bauwerkes (1) und Photovoltaikmodul (2) Dichtungsmaterialien (3) angebaut werden, die eine unkontrollierten Luftstrom verhindern. In der Skizze wurde exemplarisch Dichtungsmaterial (3) an den Anschlußpunkt zwischen Lüftungsklappen (4) und Photovoltaikmodul (2) eingesetzt.The airtightness of the system is achieved in that at all connection points of the system between the outer wall of the building ( 1 ) and photovoltaic module ( 2 ) Sealing materials ( 3 ), which prevent an uncontrolled flow of air. The sketch exemplifies sealing material ( 3 ) to the connection point between ventilation flaps ( 4 ) and photovoltaic module ( 2 ) used.

Die Wirkungsweise der vorgehängten hinterlüfteten Photovoltaikfassade zur Erwärmung des Gebäudeinneren läßt sich wie folgt
Bei geschlossenen Lüftungsklappen (4) wird die Luftschicht (7) zwischen der Außenwand des Bauwerks (1) und der vorgehängten hinterlüfteten Photovoltaikmodul (2), wie im inneren eines Wärmedämmstoffes festgehalten. Die eingeschlossenen Luftschicht (7) isoliert so das Gebäude gegen Wärmeverlust. Gleichzeitig wird über die rückseitige Wärmestrahlung der Photovoltaikmodule (2) die Außenwand des Bauwerkes (1) zusätzlich erwärmt. Die zusätzliche Wärmeenergie, die von dem Photovoltaikmodul (2) ausgestrahlt wird, trifft auf die Außenwand eines Bauwerkes (1) und diffundiert in das Gebäudeinnere, wo es als Wärmestrahlung in die Räumlichkeiten abgegeben wird.The mode of action of the ventilated rear-ventilated photovoltaic façade for heating the building interior can be as follows
With closed ventilation flaps ( 4 ) the air layer ( 7 ) between the outer wall of the building ( 1 ) and the rear-ventilated photovoltaic module ( 2 ), as held inside a thermal insulation material. The trapped air layer ( 7 ) Insulates the building against heat loss. At the same time, the back heat radiation of the photovoltaic modules ( 2 ) the outer wall of the building ( 1 ) additionally heated. The additional heat energy generated by the photovoltaic module ( 2 ), hits the outer wall of a building ( 1 ) and diffuses into the building interior, where it is emitted as heat radiation in the premises.

Die Wirkungsweise der vorgehängten hinterlüfteten Photovoltaikfassade zur Kühlung des Gebäudeinneren läßt sich wie folgt beschreiben:
Bei geöffneten Lüftungsklappen (4) steigt die erwärmte Luftschicht (7) nach oben und transportiert somit die Wärmeenergie der Photovoltaikmodule (2) und der Außenwand des Bauwerks (1) weg. Gleichzeitig entzieht die bewegte Luftschicht (7) Bauteilen, an der sie vorbei strömt Wärmeenergie (= Kühlschrankeffekt). Die im Gebäudeinneren befindliche Wärmeenergie diffundiert durch die Außenwand des Bauwerks (1) nach außen und wird über die vorbei strömende Luftschicht (7) aufgenommen und abtransportiert. Die Folge ist, daß das Gebäudeinnere gekühlt wird. Die, in den Zwischenraum zwischen Außenwand des Bauwerkes (1) und vorgehängter hinterlüfteter Photovoltaikmodul (2) nach strömende kühler Luftschicht (7) kühlt die Photovoltaikmodule (2) und die Außenwand des Bauwerks (1) zusätzlich.The mode of operation of the ventilated rear-ventilated photovoltaic façade for cooling the Ge Building interior can be described as follows:
With open ventilation flaps ( 4 ) the heated air layer rises ( 7 ) and thus transports the heat energy of the photovoltaic modules ( 2 ) and the outer wall of the building ( 1 ) path. At the same time, the moving air layer ( 7 ) Components, where it flows past Heat energy (= refrigerator effect). The heat energy inside the building diffuses through the outer wall of the building ( 1 ) to the outside and is over the passing air layer ( 7 ) and transported away. The result is that the building interior is cooled. The, in the space between the outer wall of the building ( 1 ) and rear ventilated photovoltaic module ( 2 ) after flowing cool air layer ( 7 ) cools the photovoltaic modules ( 2 ) and the outer wall of the building ( 1 ) additionally.

Verstärkt werden kann dieser Effekt durch eine zusätzliche Kühlung der einströmenden Luftschicht (7) über einen Wärmetauscher (5). Als Nebeneffekt wird erreicht, daß kühlere Photovoltaikmodule (2) effektiver Arbeiten und mehr Strom erzeugen als ungekühlte Photovoltaikmodule (2).This effect can be enhanced by additional cooling of the incoming air layer ( 7 ) via a heat exchanger ( 5 ). As a side effect is achieved that cooler photovoltaic modules ( 2 ) work more effectively and generate more electricity than non-cooled photovoltaic modules ( 2 ).

Verstärkt werden kann dieser Effekt durch eine zusätzlichen Befeuchtungsanlage (6) zur Befeuchtung der Photovoltaikmodule (2) und der Außenwand des Bauwerks (1). Durch die einsetzenden Verdunstung der Feuchtigkeit auf der Oberfläche der Photovoltaikmodule (2) und der Außenwand des Bauwerks (1) werden diese zusätzlich gekühlt. Als Nebeneffekt wird erreicht, daß kühlere Photovoltaikmodule (2) effektiver Arbeiten und mehr Strom erzeugen als ungekühlte Photovoltaikmodule (2).This effect can be enhanced by an additional humidification system ( 6 ) for moistening the photovoltaic modules ( 2 ) and the outer wall of the building ( 1 ). Due to the onset of moisture evaporation on the surface of the photovoltaic modules ( 2 ) and the outer wall of the building ( 1 ) These are additionally cooled. As a side effect is achieved that cooler photovoltaic modules ( 2 ) work more effectively and generate more electricity than non-cooled photovoltaic modules ( 2 ).
