Abstract The invention is directed to a system which constitutes a see-through portion of an enclosure, such as a wall or window portion of a building, and is operative to collect heat from solar radiation and transfer it to a utilization location. In accordance with the invention there is provided a light-transmissive exterior wall member and a light-transmissive interior wall member spaced from the exterior wall member and substantially parallel thereto. At least one heat-absorbing member is mounted in the space between the exterior and interior wall members. Fluid means, preferably air, occupies the remaining space between the inner and outer wall members, the fluid means being operative to receive heat energy from the heat absorbing member. Means are provided for recirculating the fluid between the utilization location and the space between the inner and outer wall members. In one embodiment of the invention a plurality of substantially spaced parallel slats are mounted in the space between the exterior and interior wall members, the slats having at least one heat-absorbing surface. The recirculating air is constrained to travel either vertically or horizontally over the slats so as to receive heat therefrom. In another embodiment of the invention a partially light-transmissive heat-absorbing pane is mounted in spaced substantially parallel relationship to both the exterior and interior wall members. The pane is transmissive enough of visible wavelengths to allow good visibility through the system, but is sufficiently heat-absorbing to provide an adequate heat transfer to air which recirculates in the remaining space between the inner and outer wall members; i.e., on both sides of the pane.
A system which constitutes a see-through portion of an enclosure and is operative to collect heat from solar radiation and transfer it to a utilization location comprising: a light-transmissive exterior wall member; a light-transmissive interior wall member spaced from said exterior wall member and substantially parallel thereto; a see-through heat-absorbing pane of tinted glass mounted between said wall members in spaced substantially parallel relationship to both said wall members, the combination of said wall members and said pane providing unobstructed visibility; a heat conducting fluid disposed between said heat absorbing pane and said light transmissive exterior and interior members; and means for recirculating said fluid between the utilization location and said space between said inner and outer wall members.
