Abstract
Abstract The invention relates to a heating system comprising a compressor for supplying a heated medium, preferably a heated gas, for example Freon gas, to two pipe coils each adapted to heat one fluid by means of the medium, the fluid flowing through the pipe coils and from the pipe coils to the compressor. One fluid is stored within a tank through which one of the pipe coils extends. The other fluid is supplied by a regulator to a heat exchanger wrapped around the tank and second pipe coil. The compressor and regulator as well as flow of medium to the two pipe coils are controlled as a function of the temperatures of the two fluids.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A heating system for heating first and second fluids, comprising: compressor means for heating a heat exchange medium, such as Freon, to a gas; means for supplying the medium from said compressor means to first and second, parallel pipe coils; valve means for controlling amounts of said medium supplied to said first and second pipe coils; a tank for storing said first fluid to be heated; said first pipe coil in said tank being submerged in said first fluid; said second pipe coil external to and in thermal contact with said tank; means for supplying said second fluid into thermal contact with said second pipe coil; evaporator means external to and in proximity with said second pipe coil; means for supplying the medium, condensed in said first and second pipe coils, to said evaporator means for evaporation; and means for returning the evaporated medium to said compressor.
Claim 2
Dependent Claim
147 words
A heating system for heating first and second fluids, comprising: compressor means for heating a heat exchange medium, such as Freon, to a gas; means for supplying the medium from said compressor means to first and second, parallel pipe coils; valve means for controlling amounts of said medium supplied to said first and second pipe coils; a tank for storing said first fluid to be heated; said first pipe coil in said tank being submerged in said first fluid; said second pipe coil external to and in thermal contact with said tank; means for supplying said second fluid into thermal contact with said second pipe coil; evaporator means external to and in proximity with said second pipe coil; means for supplying the medium, condensed in said first and second pipe coils, to said evaporator means for evaporation; and means for returning the evaporated medium to said compressor.
Claim 3
Dependent Claim
34 words
The system of claim 1, including: means for sensing a temperature of said first and second fluids; and means responsive to said temperature sensing means for controlling an operating parameter of said heating system.
Claim 4
Dependent Claim
14 words
The system of claim 1, including an expansion valve upstream from the evaporator means.
Claim 5
Dependent Claim
31 words
The system of claim 1, including a receiver for receiving the condensed medium from said first and second pipe coils and a distributor valve for controlling flow of said condensed medium.
Claim 6
Dependent Claim
31 words
The system of claim 1, wherein said second pipe coil is disposed in a heat exchange jacket wrapped around said tank, said second fluid being supplied to said heat exchange jacket.
Claim 7
Dependent Claim
16 words
The system of claim 5, wherein said evaporator means is wrapped around said heat exchanger jacket.
Claim 8
Dependent Claim
17 words
The system of claim 2, wherein said temperature responsive means includes means for controlling said compressor means.
Claim 9
Dependent Claim
17 words
The system of claim 2, wherein said temperature responsive means includes means for controlling said regulator means.
Claim 10
Dependent Claim
17 words
The system of claim 2, wherein said temperature responsive means includes means for controlling said valve means.
