Definitions

• the present invention relates to a sunroof that can be used for home heating as cooling due to its particular structure, which additionally provides isolation features from the outside.
• the same allows incorporating passive heating and cooling during construction of upper-middle class homes for users looking for biosustainable solutions in the long term at reasonable prices.
• This invention will provide heating and cooling during the whole year for a conventional house self-sufficiently, with the exception of an extremely low power consumption of the water pump and the driving means of the unfoldable cover, in warm to hot weather or moderately cold areas.
• the present invention proposes a new concept of adaptable roof, by combining both design lines previously mentioned but in a single roof, and also adding other advantages that will be discussed later.
• the roof of the present invention is made by using a single piece structural rectangular o trapezoidal cross section sheet (upper side black) (zip-rip system or similar), that by using omega profiles proposed in an embodiment of the invention allow to support transparent sheets and create water and air chambers, and by disposing in a preferred embodiment a unfoldable reflective upper cover, creating a smart roof design adaptable to different environmental conditions, such as day/night, summer/winter.
• an external water chamber is formed (pumping the water inventory over a second glass) to overcool the same (by evaporation and radiation), deriving the same in the day to the roof-first glass chamber (preferably protected by a unfolded reflective screen or by a water bed formed by flowing liquid over the second laminar element of the roof), to provide cooling of the habitat by natural conversion from this upper cold source.
• the liquid flowing over the second laminar element is an opaque or reflective liquid to block the solar radiation toward the roof in the configuration of use summer-day and to protect the transparent surfaces from hail.
• the reflective screen is deployed (or the external surface of the second laminar element flooded with the opaque liquid) in case of hail or snow to protect the glass upper roof.
• This upper reflective cover or screen will be folded or turned up over one of the sides of the roof using for example any of the mechanisms used with curtains or external awnings, since unlike other designs of the previous art the cover does not have any other requirement than a conventional awning.
• the annual power saving (electricity and/or fossil fuels) that provides the present invention adds to an initial investment equal to conventional constructions, due to the avoidance of conventional isolation layers (ridges, insulating material, etc.) and cooling systems.

• the sunroof of the present invention comprises a sliding reflective cover 1, which is separated and disposed over a first transparent laminar element 2, preferably made of glass, which rests on omega profiles 3 located over the side portions of the sheets 4, that are planar but forming steps on both ends, whereby they join to each other to the contiguous sheets, that form the roof of the room or place to heat.
• first transparent laminar element 2 preferably made of glass
• omega profiles 3 located over the side portions of the sheets 4, that are planar but forming steps on both ends, whereby they join to each other to the contiguous sheets, that form the roof of the room or place to heat.
• second transparent laminar elements 5 are positioned, preferably made of glass, forming between said second transparent material laminar elements and the sheets 4 a watertight or air chamber 6, and between the first and second laminar elements an air chamber 7.
• Arrows 8 shown in Figure 1 correspond to the radiation heat directed from the lower surface of the sheets 4 to the room to air-condition.
• Figure 2 shows a configuration of use of the roof elements to be used preferably in winter and during the day. There is a very light slope of the roof indicated, that allows to drain water well but keeping a level of liquid through all the extension under the joints between the sheets, made on an upper step, without compromising in this way permeability of the metal roof.
• the sliding reflective cover 1 is there totally folded to allow sunlight heating the water inside the chamber 6.
• FIG 3 shows in a more detailed manner the preferred movement of water in a room.
• the water from conduit 10 can be directed to a water heater 11 to exit then to a device that consumes the water such as a shower (conduit 12).
• FIG. 1 At night, also in winter, and as shown in figure 4, the reflective cover 1 is extended to thermally isolate from the snow or rainwater the chambers and the air-conditioned room. It is shown the cold water inlet 9 and the hot water outlet 10, that are used to drain chamber 6 to form three separate and parallel air chambers on the sheet 4, that contribute together to efficiently isolate the roof.
• the highly reflective unfoldable cover by its upper and lower side, also contributes to reflect the infrared radiation from the roof 4, avoiding heat losses by this mechanism.
• Figure 5 shows an embodiment of the sunroof in summer and during the day, wherein the reflective cover is unfolded to reject sunlight, and chamber 6 remains full of cooled water during the night cycle, to provide passive refrigeration from the roof 4 to the house.
• FIG. 6 shows the summer situation during the night, wherein the cover upper air chamber 2 contained by the sides is now a water chamber. Being the cover 1 unfolded and by external temperature water evaporates from the upper chamber which reduces temperature of said water that can be sent then to the lower chamber during the day to cool the room as explained previously.
