Abstract
Abstract A heat-exchanging system for an enclosed space having wall-forming members, pipes provided on said members, and being adapted for discharging water for flow along the surfaces of the same, a source of water, a pump connecting said source and said pipes, ducts for returning water to said source, and a temperature sensor controlling the operation of said pump whereby said members serve as a heat exchanger for both heating and cooling purposes in response to predetermined temperatures.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
192 words
For use in regulating the temperature in an enclosed space having at least one structural wall-forming member having both thermal storage and heat-insulating properties and having an interior surface directed inwardly of the enclosed space not normally intended for directly receiving solar radiation, a heat exchanging system comprising storage means for storing a body of heat exchanging liquid, means for directing flow of heat exchanging liquid downwardly along the interior surface of the wall-forming member, pump means for pumping the heat exchanging liquid from the storage means to the flow directing means for causing flow thereof downwardly along the interior surface of the wall-forming member to cause heat transfer between the wall-forming member and the heat exchanging liquid whereby to maintain a temperature of the wall-forming member commensurate with a temperature of the heat exchanging liquid, thereby to bring about heat transfer between the wall-forming member and the enclosed space for maintaining the enclosed space at a desired temperature, and flow return means for returning to the storage means the heat exchanging liquid which has flowed downwardly along the interior surface of the wall-forming member for cycling of the heat exchanging liquid.
Claim 2
Dependent Claim
192 words
For use in regulating the temperature in an enclosed space having at least one structural wall-forming member having both thermal storage and heat-insulating properties and having an interior surface directed inwardly of the enclosed space not normally intended for directly receiving solar radiation, a heat exchanging system comprising storage means for storing a body of heat exchanging liquid, means for directing flow of heat exchanging liquid downwardly along the interior surface of the wall-forming member, pump means for pumping the heat exchanging liquid from the storage means to the flow directing means for causing flow thereof downwardly along the interior surface of the wall-forming member to cause heat transfer between the wall-forming member and the heat exchanging liquid whereby to maintain a temperature of the wall-forming member commensurate with a temperature of the heat exchanging liquid, thereby to bring about heat transfer between the wall-forming member and the enclosed space for maintaining the enclosed space at a desired temperature, and flow return means for returning to the storage means the heat exchanging liquid which has flowed downwardly along the interior surface of the wall-forming member for cycling of the heat exchanging liquid.
Claim 3
Dependent Claim
15 words
A heat exchanging system according to claim 1 wherein the heat exchanging liquid is water.
Claim 4
Dependent Claim
16 words
A heat exchanging system according to claim 2 wherein the storage means comprises a swimming pool.
Claim 5
Dependent Claim
28 words
A heat exchanging system according to claim 3 wherein the storage means further comprises a balancing tank for receiving the heat exchanging fluid from the return flow means.
Claim 6
Dependent Claim
26 words
A heat exchanging system according to claim 4 wherein the return flow means is of groove-defining character and extends along a base of the wall-defining member.
Claim 7
Dependent Claim
44 words
A heat exchanging system according to claim 3 wherein there is a floor between the swimming pool and the wall-defining member, the return flow means comprising at least one trough in the floor at a location between the swimming pool and the wall-defining member.
Claim 8
Dependent Claim
14 words
A heat exchanging system according to claim 2 wherein the wall-forming member is concrete.
Claim 9
Dependent Claim
49 words
A heat exchanging system according to claim 2 wherein the flow directing means comprises a conduit system interconnected with the pump means and including a conduit extending along an upper extent of the wall-forming member and having outlets for sprinkling discharge upon the interior surface of the wall-forming member.
Claim 10
Dependent Claim
39 words
A heat exchanging system according to claim 2 wherein the heat exchanging and further comprising temperature sensing means responsive to the surface temperature of the wall-forming member for controlling the pump means as a function of such surface temperature.
Claim 11
Dependent Claim
42 words
A heat exchanging system according to claim 9 wherein the body of heat exchanging liquid is part of a water circulatory system for delivery of water to and from a swimming pool, including water warming means associated with such water circulatory system.
Claim 12
Dependent Claim
26 words
A heat exchanging system according to claim 9 wherein the water is used for heating of the wall-forming member to provide heating of the enclosed space.
Claim 13
Dependent Claim
26 words
A heat exchanging system according to claim 9 wherein the water is used for cooling of the wall-forming member to provide cooling of the enclosed space.
