Vorrichtung zum Auffangen von Sonnenenergie und zur Übertragung auf einen zu heizenden Empfänger

摘要

The invention relates to a device for collecting solar energy and transferring it to a receiver to be heated. The device comprises a plurality of essentially horizontal profiled elements (16) spaced one from another and superposed to form a curtain having an external face (18) capable of being exposed to solar radiation and an internal face (20) capable of being arranged on the side of the receiver (12), the profiled elements (16) having two reflecting faces and a profile of a shape which is selected so as to define between them a plurality of directed air ducts (28) rising from the external face to the internal face, means of closing (30) being provided on the side of the internal face to immobilise the air contained in the ducts. Application in particular to heating buildings.
