BUILDING HEATING SYSTEM SOLAR PANEL Russian patent published in 1994 - IPC

FIELD: building solar-energy engineering. SUBSTANCE: panel has face lining 1 with optical lenses 2 concentrating sun light on the ends of heat-conducting rods 4 connected to a heat energy receiver in the form of a heat-accumulating layer. The heat-accumulating layer is made from tight concrete 5 with fine-grained and dispersed reinforcement. A heat insulation from light concrete 7 is located between the face lining and the heat-accumulating layer. Conical cavities are made in the layer of light concrete between the optical lenses and the ends of the heat-conducting rods. EFFECT: improved structure. 3 cl, 3 dwg
