Abstract

1442334 Solar devices N LAING 21 June 1973 [23 June 1972] 29513/73 Heading F4U [Also in Division E1] A structure to be exposed to solar radiation for heating or cooling purposes comprises a first layer 102 of material suitable either to absorb incident visible solar radiation or to omit infra-red radiation, and a second layer 103 completely covering said first layer and formed of a plurality of closed elongate ducts. The ducts allow solar radiation to pass therethrough, but prevent heat exchange between the first layer and the atmosphere by convection.
