Diese besteht bei dem dargestellten Ausführungsbeispiel aus durchgehenden, sich kr@uzenden horizentalen Luftkanälen 12 und 13, die an den gegenüberliegenden Gebäudeseiten in sich konisch erweiternden Ein-und Austrittsöffnungen 14 bzw. 15 enden. Außerden ist ein aufsteigender Luftkanal 16 vergeschen, der am Scheitel der Dachkonstruktion 11 in einer Öffnung 17 endet. Dieser aufsteigende Luftkanal 16 kann ggfls. auch von einem Gebäudeschornstein für die Ableitung der Verbrennungsgase einer Gebäudeheizung gebildet sein. Dar aufsteigende Luftkanal 16 schneidet die horizontalen Luftkanäle 12 und 13 an ihrer Kreuzungsstelle.In the drawing, 10 denotes a house in whose roof construction 11 an energy generation device is integrated. This exists in the case of the one shown Embodiment of continuous, crooked horizontal air ducts 12 and 13, which widen conically on the opposite sides of the building Inlet and outlet openings 14 and 15 respectively end. There is also an ascending air duct 16 vergeschen, which ends in an opening 17 at the apex of the roof structure 11. This rising air duct 16 can, if necessary. also from a building chimney for the discharge of the combustion gases of a building heating system must be formed. Dar ascending Air duct 16 intersects the horizontal air ducts 12 and 13 at their intersection.

Die Luftkanäle 12, 13 und 16 sind so angeordnet, daß bei jeder Windrichtung ein definierter Luftstrom vorhnden ist, wobei ein Teil der Öffnungen 14, 15, 17 die Luftansaugöffnungen und mindestens eine dieser Öffnungen die Luftauslaßöffnung bildet. Auch bei Windstille stellt sich in den Kanal 16 aufgrund des Schornstoineffekts ein aufsteigender Luftstron ein.The air ducts 12, 13 and 16 are arranged so that in each wind direction a defined air flow is present, some of the openings 14, 15, 17 the air intake openings and at least one of these openings the air outlet opening forms.

In den Kanalsystem sind Propeller bzw. Windräder 18 und 19 angeordnet. Die Windräder 18 liegen in den horizontalen Luftkanälen 12 und 13, während das Windrad 19 in dem aufsteigenden Luftkanal 16 angeordnet ist. Sämtliche Windräder 18 und 19 arbeiten über ihre Wellen 20 auf einen geneinsamen Stro@generator 21, der sich an der Kreuzungsstelle in Inneren des Kanalsystems befindet. Es besteht aber auch die Möglichkeit, jedem Windrad oder jedem Windradpaar einen eigenen Stro@generator zuzuordnen.Propellers or wind turbines 18 and 19 are arranged in the channel system. The wind turbines 18 lie in the horizontal air ducts 12 and 13, while the wind turbine 19 is arranged in the ascending air duct 16. All wind turbines 18 and 19 work via their shafts 20 on a common Stro @ generator 21, which is is located at the intersection inside the sewer system. But it also exists the Possibility of assigning a separate Stro @ generator to each wind turbine or each wind turbine pair.

Die in dem Kanalsystem angeordneten Windräder 18, 19 werden durch die durchströmende Luft angetrieben, wobei zugleich der Sogeffekt eines Luftstromes sowie der Kamineffekt in einem aufsteigenden Luftkanal ausgenutzt werden können. Die erzeugte elektrische Bergie kann zur Deckung des Energiebedarfs im Wohnhaus verwendet werden Es empfiehlt sich, den Luftstrom in dem Kanalsystem dadurch zu erhöhen, daß Vorrichtungen zur Erwärmung der durchströmenden Luftvvorgeschen werden. Vorzugsweise wird zur Lufterwärmung die Sonnenenargie ausgenutzt, indem der Luftstrom oder Teile des Kanalsystems durch die Sonnenenergie aufgeheizt wird bzw. werden. Dies läßt sich mittels bekannter Solarzellen oder in einfacher Weise auch dadurch erreichen, daß z.B. an einzelnen Auslaßöffnungen 14, 15, 17 des Kanalsystems Vorrichtungen 22 angeordnet werden, die nach dem Brennglaseffekt arbeiten, die einfallenden Sonnenstrahlen also sanieln und gegen die betreffende Einlaß-Öffnung richten, wie dies in Fig. 3 schematisch dargestellt ist. Der Luftst@om kann, wie in Fig. 3 durch Pfeile angedeutet, hinter der brennglasartigen Vorrichtung 22 von der Seite her in die Einlaßöffnung 14 gelangen.The wind turbines 18, 19 arranged in the channel system are through the air flowing through is driven, at the same time the suction effect of an air flow and the chimney effect can be used in an ascending air duct. The generated electrical mountain can be used to cover the energy demand in the house It is recommended that the air flow in the duct system be blocked by this increase that devices for heating the air flowing through are provided.
