Abstract
Roof structure for transparent roofs with girders (11), each with a solar panel (15, 36). The girders preferably have a height equal to have the distance between each girder. Two trapdoors (13, 14), consisting of thermal insulating material (28), are located between each pair of girders, one on the underside of each girder, which can swing on its pivot axis on the girder between horizontal and vertical positions. In the horizontal position the trapdoors shield against heat loss, in the vertical position they allow all light to enter, and in the intermediate position incoming light is reflected towards the sides of the girders (15) for heat absorbtion.
Claims7
A roof structure for transparent roofs, consisting of a number of support girders, wherein at least a part of each girder includes a sheet-formed solar panel which is operatively connected to a heat exchanger for a medium for heat transference, characterized by the fact that the solar panel is connected to a side surface of the girder and that the solar panels are designed for receiving a fluid that can transfer heat, and that in the space between two girders is placed at least one element means, said element means having an upward-facing reflecting side and including means for moving it between various positions in relation to the solar panel and the opening between adjacent girders.
