Abstract
A dark colored absorbing substrate covered with monolayer of solar radiation, transparent spheres, absorbs solar radiation for heating an air column formed between drapery material and the substrate mounted inside of a transparent window. In one form, a drapery material forms with the substrate a series of tubes for naturally or forcibly circulating warm air through the tubes when the substrate is heated by solar radiation. In another form, a eutectic salt in the tubes stores heat by transending to a higher energy state, so as to subsequently radiate heat on returning to a lower energy state. Reflecting cover means, selectively mountable in front of the substrate, reflects solar radiation back through the transparent window when heating is not required.
Claims8
A room window covering for utilizing solar radiation, comprising
- a. solar radiation collector means arranged to be positioned adjacent a window and cover at least a portion of the window for absorption of solar radiation passing the window, said collector means including a flexible thin, dark colored fabric-like substrate and a monolayer of solar radiation transparent spheres secured to the window facing surface thereof,
- b. an overlaying pleated drapery material window covering means adjacent said collector means on the side opposite said spheres, and positioned to provide a plurality of tubular type vertical passages therebetween for passage of air, and
- c. said overlaying covering means being provided with an upper and a lower room opening for each tubular type passage permitting the passage of air to and from different elevations in the room.
A method of heating an enclosed space having a window in position to be contacted by solar radiation, comprising
- a. placing a generally planar fabric-like, dark absorber of solar radiation having secured on the window side a mono-layer of focusing spheres on the enclosed space side of the window and adjacent said window,
- b. placing a pleated fabric on the enclosed space side of said absorber and closely adjacent thereto, so as to form a plurality of tubular passages for an effective air passage therebetween, and
- c. subjecting said absorber to solar radiation so as to heat air in said air passage for circulation in said space.
