Abstract

A sunroof, which is adapted to provide either home passive heating by solar accumulation or passive refrigeration due to its particular structure that additionally provides insulation conditions from the external environment. The sunroof allows incorporating heating and refrigeration during construction of homes for users looking for biosustainable solutions in the long term at present reasonable prices and included in moderately innovative products. The sunroof is comprised by structural sheets (preferable metallic) over which substantially parallel first and second transparent laminar elements are positioned, defining between such sheets and the first laminar elements a first chamber, and forming between first and second laminar elements a second watertight chamber; the first chamber is capable of being filled with water as the external and upper surface of the second transparent laminar element, which is filled with water or opaque and/or reflective liquids. Preferably, a stationary reflective cover is positioned over the laminar elements.

Claims

1. A sunroof characterized in that comprises structural profile sheets over which substantially parallel first and second transparent laminar elements are positioned, defining between said sheets and the first laminar elements a first chamber, and forming between first and second laminar elements a second chamber;

having the first chamber inlet and outlet water conduits;

being the second transparent laminar element capable of permitting the flow of a liquid over its external surface.

2. A sunroof according to claim 1, characterized in that a stationary reflective cover is disposed over the second transparent laminar element, forming an intermediate air chamber.

3. A sunroof according to claim 1, characterized in that said first and second surface are made of glass, and as the sheets, said surfaces are disposed substantially horizontally.

4. A sunroof according to claim 1, characterized in that an omega profile is disposed between the join edges of two contiguous sheets to support the first transparent surface.

5. A sunroof according to claim 1, characterized in that the structural profile sheets form an upper step where they join.

6. A sunroof according to claim 1, characterized in that the external face of the structural sheet, that forms the water chamber, is metallic and black.

7. A sunroof according to claim 1, characterized in that the inner face of the metallic sheet, in contact with the environment, is painted with different colors according to the room to air-condition, (to provide a different level of heating by infrared radiation).

8. A sunroof according to claim 2, characterized in that a cylinder is positioned adjacent to the roof over which said stationary reflective cover is folded.

9. A sunroof according to claim 1, characterized in that the liquid flowing over the second transparent laminar element is a opaque or reflective liquid (to block the solar radiation to the roof in the configuration summer-day and to protect the transparent surfaces from hail, while water is used in this position, in the configuration summer-night, to cool this water, which is bypassed during the day to the first chamber, to cool the habitat).

10. A sunroof according to claim 1, characterized in that the sunroof is positioned on a sloped surface.
