Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A solar heating unit being adapted for mounting in proximity to a heated building comprising: a planar floor section, a plurality of intersecting panels positioned on said floor section and forming a plurality of cells, means interconnecting said panels at the intersections of said panels, each of said cells having mutually abutting rear side walls and front side walls, said rear side and front side walls being at an acute angle to said planar floor section, each cell including a front side wall and a rear side wall that are in parallel planes, at least some of said side walls of each cell being coated black, a cover means over said cells for admitting light energy and retaining heated air, circulation means for circulating a working fluid in heat transfer relationship with said cells for extracting heat converted from solar energy by said cells and for delivering said extracted heat to the heated building.
Claim 2
Dependent Claim
