Claim 1
Independent Claim
339 words
A heating and cooling system for use in a dwelling comprising, a fluid source of heat, a source of fluid heat transfer media, a closed circuit heat transfer system comprising a recirculating thermosiphon heat transfer unit having an inner pipe disposed within an outer pipe to define a coaxial pipe having an annulus therebetween, said pipes being coiled to form a coil helix, container means for holding a fixed level of a liquid phase of the fluid heat transfer media, one end of said inner pipe being connected to the bottom of said container means with the liquid phase of said fluid heat transfer media flowing therethrough, the opposite end of said inner pipe being connected to said container means above the level of the liquid phase of said fluid heat transfer media, the outer of said pipes being connected at its one end to the pipes containing the source of fluid heat, the opposite end of said outer pipe being connected to means to enable a self-draining flow of said fluid heat source through said annulus, variable capacity compressor means connecting with said container means being operable to move the fluid heat transfer media through said system at a controllable mass rate, the input of said compressor means being connected with said container means above the level of the fluid phase of said media disposed therein, the flow of said fluid heat source being effective to cause at least a partial vaporization of the heat transfer media in said inner pipe being operable to separate said media into a liquid phase and a vapor phase whereby said media flows through said inner pipe absorbing the heat of vaporization, the liquid phase of said heat transfer media returning to the lower part of said container means and the vapor phase of said heat transfer media returning to the input of said compressor means, and heat exchanger means operatively connected to the output of said compressor for receiving the vapor phase of said heat transfer media and removing heat therefrom.

A heating and cooling system for use in a dwelling comprising, a fluid source of heat, a source of fluid heat transfer media, a closed circuit heat transfer system comprising a recirculating thermosiphon heat transfer unit having an inner pipe disposed within an outer pipe to define a coaxial pipe having an annulus therebetween, said pipes being coiled to form a coil helix, container means for holding a fixed level of a liquid phase of the fluid heat transfer media, one end of said inner pipe being connected to the bottom of said container means with the liquid phase of said fluid heat transfer media flowing therethrough, the opposite end of said inner pipe being connected to said container means above the level of the liquid phase of said fluid heat transfer media, the outer of said pipes being connected at its one end to the pipes containing the source of fluid heat, the opposite end of said outer pipe being connected to means to enable a self-draining flow of said fluid heat source through said annulus, variable capacity compressor means connecting with said container means being operable to move the fluid heat transfer media through said system at a controllable mass rate, the input of said compressor means being connected with said container means above the level of the fluid phase of said media disposed therein, the flow of said fluid heat source being effective to cause at least a partial vaporization of the heat transfer media in said inner pipe being operable to separate said media into a liquid phase and a vapor phase whereby said media flows through said inner pipe absorbing the heat of vaporization, the liquid phase of said heat transfer media returning to the lower part of said container means and the vapor phase of said heat transfer media returning to the input of said compressor means, and heat exchanger means operatively connected to the output of said compressor for receiving the vapor phase of said heat transfer media and removing heat therefrom.
Claim 3
Dependent Claim
38 words
A heating and cooling system as is defined in claim 1 and wherein the pipes are coiled to form a plurality of separate coil helix each having means to control the flow of the fluid heat source therethrough.
Claim 4
Dependent Claim
36 words
A heating and cooling system as is defined in claim 2 and wherein the plurality of coil helix are interconnected to provide a parallel flow therethrough of the heat transfer media and the fluid heat source.
Claim 5
Dependent Claim
49 words
A heating and cooling system as is defined in claim 2 and wherein each of the coil helix is provided with a different size of heat transfer surface area which may be selectively activated to provide various combinations of surface areas effective to modulate the thermosiphon heat transfer unit.
Claim 6
Dependent Claim
30 words
A heating and cooling system as is defined in claim 2 and which comprises three separate coil helix each of which has a different size of heat transfer surface area.
