Abstract:
1. A smart device for absorbing solar energy and controlling sunlight admission comprising: a pair of transparent plates; a fixed outer frame supporting the transparent plates, configured to be mounted on an outside of a building; a moving inner frame supporting the transparent plates being an inner frame attached to the fixed outer frame by a flexible membrane, the inner frame configured to be placed inside the building; a channel surrounding the inner frame and which is filled with a liquid; a reservoir connected to the channel by means of a tube that goes through a retaining valve which allows under vacuum a compensation of a liquid column pressure on a base of the transparent plates and; a valve which allows changing thickness of the liquid, thus regulating sunlight admission, the valve being installed in a tube that connects a liquid reservoir to a vacuum system, and the valve provides a connection between the reservoir and the channel; a circulation pump, activated by a switch, that functions when the transparent plates are spaced apart by the liquid, ensuring a cooling process and thermal energy absorption for the window and making the liquid circulate through a heat exchanger; wherein a darkening regulation is carried out simultaneously by valve control which enables air flow into the reservoir through the tube and through the valve which allows a laminar flow of the liquid between the transparent plates, and wherein liquid removal from the channel into a gap between the transparent plates, whose distance is variable and/or adjustable, is made simultaneously through a perimeter of the inner frame.
