[Problem] To provide a light-concentrating mechanism that is suitable for photovoltaic power generation. [Solution] This light-concentrating mechanism comprises an angle-selective reflection means that reflects light having an incident angle of at least a first threshold angle and transmits at least some of the light having an incident angle smaller than the first threshold angle, and an angle-increase reflection means that reflects incident light at an angle greater than the incident angle of said light, the two means being arranged so as to have a gap therebetween. The angle-increase reflection means reflects, at an angle that is equal to or greater than the first threshold angle, at least some of the light that has been transmitted by the angle-selective reflection means, and the angle-selective reflection means reflects the light that has been reflected by the angle-increase reflection means and has an angle that is equal to or greater than the first threshold angle, and light is propagated and concentrated by the gap between the angle-selective reflection means and the angle-increase reflection means.

A window comprises a first at least partially transparent or translucent sheet or panel 3 and at least one body 4 located adjacent a major surface of the first sheet or panel. The or each body bounds a cavity containing a vacuum. Preferably, the bodies are constituted as an array of parallel evacuated tubes. Optionally, each tube contains a second tube 5 arranged inside it, with the vacuum contained between the two tubes. The window may have a second pane 6. A getter may be coated on a wall of each cavity. The window may further include a thermoelectric device for electricity generation. The window panel may be tinted or include a photocatalytic coating. A method of manufacture is also provided. In another aspect, a window assembly includes an air-flow channel and an air movement means.

摘要:
A solar energy collector and thermal storage device for placement in a building's exterior architectural opening is provided, having an insulating cavity including a first lite on the device exterior side and a second lite spaced inwardly therefrom, defining a depth of the insulating cavity, and being substantially filled with an insulating gas. A provided thermal storage cavity includes the second lite and a third lite spaced inwardly therefrom, defining a depth of the thermal storage cavity which is at least the same size as the insulating cavity depth, and is substantially filled with a thermal storage medium, which is a hydrogel adhering to the second lite and the third lite and having cohesion characteristics such that it is self supporting and maintains its shape within the thermal storage cavity. A low-emissivity coating disposed on the insulating cavity side of the second lite inhibits exterior thermal radiation transfer.

The present invention provides a process for absorbing solar energy and, simultaneously having a continuous control of the light admission making it possible to install the device in external openings of buildings and equipment, such as windows, shutters or skylights. The system comprises two frames which support plates of transparent material, between which it is possible to introduce a colourful solution coming from an external reservoir. Both frames are interconnected through a flexible membrane which allows the plates to be pushed against each other, making the window transparent, or pushed away interposing the colourful solution, which will make the window uniform and gradually translucent or opaque. The said liquid comes from a reservoir and the access to the gap between the plates through is obtained by means of a channel that separates the two frames, allowing the liquid to flow evenly into the whole surface, thus being a homogenous and adjustable darkening obtainable. The inflow or outflow of the liquid between the plates is ruled by the vacuum level inside the reservoir containing the colourful solution. When the window is opaque or partially transparent, the solar energy heats the liquid which is then forced to flow by a circulating pump, passing through a heat exchanger which allows the energy absorption.

Solar collector (7) integrated in a facade characterised in that as well as fulfilling the actual function of trapping solar radiation, it acts as a means of sealing, integrated in a facade; that has exterior glazing (1), an air chamber (2) and internal double glazing (3), along with supplementary collectors (7) with the internal double glazing (3). Said collectors (7) are covered with a transparent insulation (6) on their external face, and optionally, by another sheet of glass (5). Inside the air chamber (2) a blind (4) can be placed, that covers the collector (7), preventing the reception of external heat. The collectors (7) are grouped and connected with an exchanger (10), and this in turn is connected with a reservoir (8) where the hot water is stored awaiting use.
摘要:
A honeycomb core 2 is bonded to a planar outer skin 10 by forming a pool of adhesive 24 on a surface of the outer skin and placing the honeycomb core 2 within the adhesive pool 24. In the resulting structure, a continuous layer of adhesive of substantially uniform depth is formed within the cells 8 of the honeycomb core 2. The depth of the adhesive and the size of the cells may be chosen so that the adhesive provides a lens effect on light passing through. The structures may be used for light, heat or sound transmission/retardation.
