Abstract
A light transmissive insulation system comprising a plurality of layers of light transmissive insulating material, the material being characterized by transmissivity to solar spectrum radiation, and low transmissivity to thermal radiation. A solar pond employing the insulation system is also described.
Claims12
A solar collector comprising:
- a body of material sought to be heated;
- a layer of solar spectrum radiation transmissive insulation;
- and
- means for supporting said layer of solar spectrum radiation transmissive insulation over the body of material and in spaced relationship therewith.
- said layer of solar spectrum radiation transmissive insulation comprising an array of cells,
- said array being generally transmissive to solar spectrum radiation and generally opaque to thermal radiation, and
- said array of cells being coated with a coating, which is antireflective in the wavelength range of thermal IR, thereby to enhance absorption of such radiation by the array and prevent back radiation thereof to the atmosphere and is operative to reduce scattering in the wavelength range of incident solar radiation, the thickness of the coating being generally between 0.01 and 1 micron.

Solar collector apparatus comprising:
- a body of material sought to be heated;
- a layer of solar spectrum radiation transmissive insulation;
- and
- means for supporting said layer of solar spectrum radiation transmissive insulation over the body of material and in spaced relationship therewith,
- wherein said layer of solar spectrum radiation transmissive insulation comprises an array of cells generally transmissive to solar spectrum radiation and generally opaque to thermal spectrum radiation, the array being surrounded by a generally sealed enclosure comprising planar glass panels defining top, bottom and side surfaces and being joined by sealing means, said enclosure including venting apparatus for permitting communication between the interior and exterior of the enclosure said array of cells being coated with a coating which is antireflective in the wavelength range of thermal IR, thereby to enhance absorption of such radiation by the array and prevent back radiation thereof to the atmosphere and is operative to reduce scattering in the wavelength range of incident solar radiation.
