ABSTRACT:
A flat plate solar air heater for installation between light frame structural members, which comprises a pan of sheet stock such as sheet metal with one or more substantially transparent surface sheets to admit solar radiation into a sealed chamber between said pan and the transparent sheets. A louvered structure placed behind the transparent surface sheets reflects high angle solar rays in summer yet admits low angle solar rays in winter into the black-surfaced absorbing chamber. The louvered structure also increases heat transfer to an air stream moving through the chamber, and directs most of the air flow against the absorber surface. The top and bottom of the pan may be chamfered to permit various ductwork connections.
