Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 218 words
An improved heating and cooling system comprising: a structure having at least one interior thermal storage wall, a plurality of interior partition walls, a floor, a ceiling, and a roof; at least a portion of said thermal storage wall being constructed of a relatively high density material capable of storing alternately relatively large amounts of positive and negative BTU's; at least a portion of said partition walls being constructed of a solar transmissive material; at least a portion of said floor being constructed from a relatively high density material capable of storing alternately relatively large amounts of positive and negative BTU's; at least a portion of said ceiling having an opening therein with an openable closure operatively associated therewith; means associated with said openable closure for reflecting solar energy onto portions of said high density wall and floor not otherwise in a position to passively receive solar energy; a relatively transparent glazing covering said ceiling opening; and at least a portion of said roof having an equatorial exposure with relatively transparent glazing forming the cover thereof whereby when it is desired to passively collect solar energy, the closure over said ceiling opening can be opened to allow solar energy to pass through said roof, through said ceiling, and to be stored in said high density wall and floor.
Claim 2
Dependent Claim 218 words
An improved heating and cooling system comprising: a structure having at least one interior thermal storage wall, a plurality of interior partition walls, a floor, a ceiling, and a roof; at least a portion of said thermal storage wall being constructed of a relatively high density material capable of storing alternately relatively large amounts of positive and negative BTU's; at least a portion of said partition walls being constructed of a solar transmissive material; at least a portion of said floor being constructed from a relatively high density material capable of storing alternately relatively large amounts of positive and negative BTU's; at least a portion of said ceiling having an opening therein with an openable closure operatively associated therewith; means associated with said openable closure for reflecting solar energy onto portions of said high density wall and floor not otherwise in a position to passively receive solar energy; a relatively transparent glazing covering said ceiling opening; and at least a portion of said roof having an equatorial exposure with relatively transparent glazing forming the cover thereof whereby when it is desired to passively collect solar energy, the closure over said ceiling opening can be opened to allow solar energy to pass through said roof, through said ceiling, and to be stored in said high density wall and floor.
Claim 3
Dependent Claim 12 words
The improved system of claim 1 wherein said ceiling is double glazed.
Claim 4
Dependent Claim 12 words
The improved system of claim 1 wherein said ceiling closure is insulated.
Claim 5
Dependent Claim 31 words
The improved system of claim 1 wherein an openable roof vent and an openable passage through said ceiling glazing is provided whereby excess heat within said structure can be vented therefrom.
Claim 6
Dependent Claim 25 words
The improved system of claim 1 wherein air passages are provided through said storage wall whereby faster cooling can be accomplished during negative BTU storage.
Claim 7
Dependent Claim 21 words
The improved system of claim 1 wherein said means for reflecting solar energy includes a reflective surface on said openable closure.
