Abstract
Abstract A system is described for storing near infrared heat energy of the sun for use in a building including at least one glazing panel for transmitting the light and near infrared heat energy of the sun into the building. The system comprises a first tank capable of being completely filled with a heat absorbing fluid and positioned relative to the glazing panel so as to be exposed to at least a portion of the heat energy transmitted through the glazing panel and so that the heat absorbing fluid in the tank absorbs at least a part of the portion of the energy. A second tank is in fluid communication with the first tank and disposed above the first tank. The system also includes conduit means connecting the bottom of the first tank and the second tank so that fluid disposed on the bottom of the first tank will flow into the second tank when the fluid in the first tank expands, and so that fluid disposed in the second tank will flow into the first tank when the fluid in the first tank contracts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
In a building including at least one glazing panel for transmitting the light and near infrared heat energy of the sun, a system for storing said heat energy comprising in combination: a first tank capable of being completely filled with a heat absorbing fluid and positioned relative to said glazing panel so as to be exposed to at least a portion of said heat energy transmitted through said glazing panel and so that said heat absorbing fluid absorbs at least a part of said portion of heat energy, a second tank in fluid communication with said first tank and disposed above said first tank; and conduit means connecting the bottom of said first tank and said second tank so that fluid disposed on the bottom of said first tank will flow into said second tank when the fluid in said first tank expands, and so that fluid disposed in said second tank will flow into said first tank when the fluid in said first tank contracts.
Claim 2
Dependent Claim
166 words
In a building including at least one glazing panel for transmitting the light and near infrared heat energy of the sun, a system for storing said heat energy comprising in combination: a first tank capable of being completely filled with a heat absorbing fluid and positioned relative to said glazing panel so as to be exposed to at least a portion of said heat energy transmitted through said glazing panel and so that said heat absorbing fluid absorbs at least a part of said portion of heat energy, a second tank in fluid communication with said first tank and disposed above said first tank; and conduit means connecting the bottom of said first tank and said second tank so that fluid disposed on the bottom of said first tank will flow into said second tank when the fluid in said first tank expands, and so that fluid disposed in said second tank will flow into said first tank when the fluid in said first tank contracts.
Claim 3
Dependent Claim
20 words
A heat storage system in accordance with claim 1, further including a fluid disposed in said first and second tank.
Claim 4
Dependent Claim
14 words
A heat storage system in accordance with claim 2, wherein said fluid is water.
Claim 5
Dependent Claim
21 words
A heat storage device in accordance with claim 1, wherein one of said first and second tanks includes a needle valve.
Claim 6
Dependent Claim
179 words
A building structure comprising, in combination: at least one glazing panel mounted on said structure and transmissive to light and near infrared heat energy; a first tank disposed in at least a portion of a floor of said structure and positioned relative to said glazing panel so that said portion of said floor is exposed to at least a portion of said heat energy transmitted through said glazing panel; a second tank in fluid communication with said first tank and disposed above said first tank; a heat absorbing fluid disposed in at least said first tank and capable of absorbing at least a part of the portion of said heat energy exposed to said floor portion; conduit means connecting the bottom of said first tank and said second tank so that said fluid disposed on the bottom of said first tank will flow into said second tank when said fluid in said first tank expands, and so that any fluid disposed in said second tank will flow into said first tank when the fluid in said first tank contracts.
Claim 7
Dependent Claim
179 words
A building structure comprising, in combination: at least one glazing panel mounted on said structure and transmissive to light and near infrared heat energy; a first tank disposed in at least a portion of a floor of said structure and positioned relative to said glazing panel so that said portion of said floor is exposed to at least a portion of said heat energy transmitted through said glazing panel; a second tank in fluid communication with said first tank and disposed above said first tank; a heat absorbing fluid disposed in at least said first tank and capable of absorbing at least a part of the portion of said heat energy exposed to said floor portion; conduit means connecting the bottom of said first tank and said second tank so that said fluid disposed on the bottom of said first tank will flow into said second tank when said fluid in said first tank expands, and so that any fluid disposed in said second tank will flow into said first tank when the fluid in said first tank contracts.
Claim 8
Dependent Claim
21 words
A structure in accordance with claim 5 wherein said floor portion is made of a material absorptive to said heat energy.
Claim 9
Dependent Claim
12 words
A structure in accordance with claim 6, wherein said material is concrete.
Claim 10
Dependent Claim
21 words
A structure in accordance with claim 5 wherein said floor portion is made of a material transmissive to said heat energy.
