Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
An exterior wall structure facilitating rapid air changes in a building, comprising an upright exhaust duct in the wall and opening at one end within the building to receive air to be exhausted, and said duct opening at the opposite end to the exterior of the building, said duct having a heat conductive panel forming one side thereof, an upright intake duct in the wall and including said heat conductive panel as one side thereof to transfer heat from the exhaust air to the intake air, one end of said intake duct opening to the exterior of the building for receiving fresh air, and the other end of said intake duct opening into said building for supplying such fresh air into the building after the fresh air has been heated along said heat conductive panel to return heat from the exhaust air into the building.
Claim 2
Dependent Claim
145 words
An exterior wall structure facilitating rapid air changes in a building, comprising an upright exhaust duct in the wall and opening at one end within the building to receive air to be exhausted, and said duct opening at the opposite end to the exterior of the building, said duct having a heat conductive panel forming one side thereof, an upright intake duct in the wall and including said heat conductive panel as one side thereof to transfer heat from the exhaust air to the intake air, one end of said intake duct opening to the exterior of the building for receiving fresh air, and the other end of said intake duct opening into said building for supplying such fresh air into the building after the fresh air has been heated along said heat conductive panel to return heat from the exhaust air into the building.
Claim 3
Dependent Claim
62 words
The wall structure according to claim 1 and said exhaust duct and said intake duct disposed in juxtaposition with each other, separated by said heat conductive panel, the delivery end of said intake duct being adjacent the receiving end of said exhaust duct whereby the exhaust and intake air flow in opposite directions in said ducts and along said heat conductive panel.
Claim 4
Dependent Claim
31 words
The invention set forth in claim 2 and the upper end of said exhaust duct opening into the interior of the building whereby exhaust air flows downwardly through said exhaust duct.
Claim 5
Dependent Claim
58 words
The exterior wall structure according to claim 3 and including air controlling valve means closing the portion of said intake duct along said heat conductive panel and supplying fresh air directly into the building, whereby to permit the warm exhaust air to heat the heat conductive panel and crack off any accumulation of ice that may have formed.
Claim 6
Dependent Claim
39 words
The exterior wall structure according to claim 4 and there being a large and unobstructed space adjacent the lower discharge end of said exhaust duct to receive ice cracking out of said exhaust duct and falling into said space.
Claim 7
Dependent Claim
167 words
An exterior wall structure facilitating rapid air changes in a building, comprising an upright exhaust duct in the wall and opening at its upper end and within the building to receive air to be exhausted, the lower end of the duct opening to the exterior, the duct having a heat conductive panel forming one side thereof, an upright intake duct in the wall and including said heat conductive panel as one side thereof to transfer heat from exhaust air to the intake air, the upper end of the intake duct communicating with the building interior to deliver air thereto, the lower end of the intake duct receiving air for delivery to the building interior, another side of the intake duct comprising a solar heat absorption panel exposed to the exterior to receive heat and infrared radiation and said panel transmitting absorbed heat to the intake air, and means directing air from without the building along said solar heat absorption panel for heating and to said intake duct.
Claim 8
Dependent Claim
167 words
An exterior wall structure facilitating rapid air changes in a building, comprising an upright exhaust duct in the wall and opening at its upper end and within the building to receive air to be exhausted, the lower end of the duct opening to the exterior, the duct having a heat conductive panel forming one side thereof, an upright intake duct in the wall and including said heat conductive panel as one side thereof to transfer heat from exhaust air to the intake air, the upper end of the intake duct communicating with the building interior to deliver air thereto, the lower end of the intake duct receiving air for delivery to the building interior, another side of the intake duct comprising a solar heat absorption panel exposed to the exterior to receive heat and infrared radiation and said panel transmitting absorbed heat to the intake air, and means directing air from without the building along said solar heat absorption panel for heating and to said intake duct.
Claim 9
Dependent Claim
67 words
The exterior wall structure according to claim 6 and said air directing means comprising a solar heating duct with said solar heat and infrared absorption panel comprising one side thereof, the opposite side of solar heating duct comprising a solar heat and infrared transmissive panel spaced from and confronting the absorption panel to permit solar heating of the panel and to confine airflow along the surface thereof.
Claim 10
Dependent Claim
32 words
The exterior wall structure according to claim 7 wherein said solar heating duct and the intake duct extend along each other, said absorption panel also forming oNe side of said intake duct.
Claim 11
Dependent Claim
47 words
The exterior wall structure according to claim 6 and said solar heat absorption panel being perforated to permit passage of air therethrough and into said intake duct, the heat absorbed by said panel being transferred to the air passing through the perforations and into the intake duct.
