摘要:
A solar panel (FIG. 7) comprises an extruded plastics matrix (20) comprising a plurality of side-by-side compartments each of which provides an actual fluid-flow channel without the need for providing separate metal pipework. Each compartment may include a filler (62) to define a fluid-flow channel between the upper surface of the filler and the lower surface of a membrane (28) of the matrix. The provision of the filler (62) is optional and the cross section of each compartment may be optimized to the fluid-flow channel size requirements. At least part of a surface of each fluid-flow channel has a covering comprising a solar radiation absorber; for example, the absorber may comprise a channel-shaped foil (72) which exhibits high absorbence of solar energy together with low emittance of infra-red radiation.

A radiant energy redirecting system comprising a radiant energy transmitting body structure; the structure comprising multiple elements, each of which acts as a radiant energy redirecting module, having on its cross-sectional perimeter an entry face to receive incidence of the energy into the interior of the perimeter, an exit face to pass the energy to the exterior of the perimeter in a direction towards the reverse side of the body from the side of the incidence, and a Totally Internally Reflecting face angled relative to the entry and exit faces to redirect towards the exit face the radiant energy incident from the entry face; the body structure generally redirecting incident radiant energy towards a predetermined target zone situated apart from and on the reverse side of the body relative to the side of the incidence; and lens structure associated with at least one of the faces for redirecting radiant energy passing between the entry and exit faces via the Totally Internally Reflecting face.

A solar collector includes a collector body having a substantially curved collector surface. A reflective device projects from the collector body and reflects incident solar energy to the collector surface. The collector body is substantially conical and the reflective device is secured to and projects externally from the conical collector body. The reflective device has a curved surface which extends along an arc of a circle and which overlies the collector surface for reflecting incident solar radiation over a portion of the collector surface.

The solar energy apparatus of the present invention collects, concentrates, and transmits solar radiation to a light converter, which converts solar radiation to another energy form. The apparatus includes aspheric reflectors which are used in conjunction with azimuth and altitude tracking means, which controls the position of the aspheric reflectors so that each reflector focuses the solar radiation to a proximate a fixed first position as the sun's position changes during the day. Optical waveguides have their first ends located at the fixed first position. The second ends of the optical waveguides terminate at a light converter. Solar radiation received at the first ends of the optical waveguides is transmitted through the optical waveguides to the second ends, where it is converted to thermal energy by the light converter.

This invention relates to the air conditioning of a building complex comprised of one or more zones, utilizing solar insolation and terrestrial re-radiation to a maximum extent and supplemented by external energy as may be required. The principle of thermodynamic availability is employed in a water source system advantageously storing heated and chilled fluid for subsequent heat exchange, and by the diversion of high heat range fluid through a Rankine cycle prime mover for motivation of vapor compression refrigeration or the generation of electrical power dependent upon the availability of solar energy and the demand of said refrigeration, whereby heat energy is claimed and reclaimed and made available to reduce the net energy requirements necessary to provide both heating and cooling of said building complex zones.
摘要:
A reflector assembly is provided for efficiently collecting and forming the electromagnetic radiation from a radiation source into a desired beam pattern. The reflector assembly uses a smaller non-symmetrical generally convex reflector and a larger non-symmetrical generally concave reflector. The generally convex reflector intercepts a large fraction of light emitted by the source that would otherwise escape without interacting with the assembly and redirects this light onto the generally concave reflector for eventual inclusion in the beam.
