ABSTRACT OF THE DISCLOSURE
The invention provides a heating system comprising a com-pressor 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 regula-tor 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 function of the temperatures of the two fluids.

Description
l 1600~
The present invention relates to a heating system compris-- ing a compressor for feeding 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 coils and being returned from the coils to the compressor.
In such a system it is known to utilize the earth's heat or the heat of water in deep wells. Thereby the heating sys-tem is used for heating the water of a water heater and forheating the water o~ radiators.
A heating system is known in which the earth's heat is utilized and the heating medium consists of Freon (a trademark) gas. A drawback of this system is that the hot gas has to flow through a water heater before it can be conducted to a heat exchanger for heating the radiator water. This causes the temperature of the gas to be substantially reduced before the gas reaches the heat exchanger for heating the radiator water, if very much water is drained from the water heater.
The present invention provides an improved such heating system.
According to the present invention therefore there is provided a heating system for heating first and second fluids, comprising: compressor means for heating a heat exchange medium, 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 fi-rst 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 ., ~- 1 - 3~
~ 1600~7 with said second pipe coil; means for supplying the medium, condensed in said first and second pipe coils, to said evapor-ator means for evaporation; and means for returning the evap-orated medium to said compressor.
Thus, according to the present invention in the heating system the pipe coils are connected in parallel to the com-pressor and the system comprises a device for controlling the relationship between the flow of the medium through one of said coils and the flow of the medium through the other of said coils.
- la -t ~ ~OO~i7 ~ s described above it is pre~erred that the heating system is designed so th~t one of the pipe coils extends through a w-ate~ fieatex and that the other pipe coil extends through a heat exchanger for heating water of radiators.
Prefera~ly the control device is connected by a sensor wfiich is adapted to measure the temperature of the fluids heated by means of the medium, said fluids being constituted by the fiot water of the water heater and the hot water for radiators.
Thereby it is suitable that the control device automatically distributes the hot gas between the pipe coils with regard to the condensation effect in the pipe coils and the capacity demand so that the gas supply to the pipe coils ls conducted in such a way that th~ gas is completely condensed in the pipe coils.
An embodiment of the invention is described in the following with reference to the accompanying drawings, in which:
Fig. 1 is a schematical view of a heating system according to the invention; and Fig. 2 shows a detail of the system according to F~g. 1 on the enlarged scale.
A compressor 1 feeds hot Freon (a trademark) gas throu~h a pressure conduit 9 to a control valve 5. From the control valve 5 a portion of the gas is directed into a pipe coil 8 positioned ~n a water heater 4. The gas is condensed ~n the pipe coil by the fact that the gas is cooled by the water of the ~ater heater and leaves the lower end 11 of the` pipe coil in a condensed state. The ~ ~0~67 condensed ~a~ is fed to a ~eceiver 7 through a distribu-tor y~lye 10. Another portion o$ the hot Freon gas is di-rected ~rom the control valYe 5 to a pipe coil 3 which is positioned in a jacket shaped heat exchanger 15 outside the water heater 4. Water which shall be heated by the Freon Ca trademark) gas in order to heat radiators flows through the heat exchanger 15, and the Freon gas is cooled by this water to a condensed state. The condensed Freon gas is directed from the lower end of the pipe coil to the receiver 7 through t~e distributor valve 10.
From the receiver 7 there is fed condensed, liquid state Freon (a trademark), through an expansion valve 6 to a pipe coil in an evaporator 2 which as a jacket is positioned outside the jacket shaped heat exchanger 15.
An insulating materialis positioned between the heat exchanger 15 and the evaporator 2. The liquid state Freon (a trademark) will ~e evaporated in the evaporator 2 partly because of the fact that it is subjected to a pressure reduction when passing the expansion valve 6 and partly by being heated in the evaporator 2 by the water circulating around the pipe coil in the evaporator. The water is sup-plied to the upper end of the evaporator, as ~hown by me~ns of the arrow 12 in FigO 1, and escapes from the lower end of the evaporator, as shown by means of the arrow 13 in Fig. 1. The water passing through the evaporator can be const~tuted by water which is heated by means of the earth heat or by means of the water of a deep well.
The water to the radiators is supplied to the jacket shaped heat exchanger 15 through a pipe 14 and es-capes from the heat exchangex 15 through a pip~ 16 at the upper port~on of the heat exchanger.
A sensor (see Figure 2) extends into the upper end of the heat exchangex 15 and into the upper end of the ~_ 3 _ water heater 4 in o~der to sense the temperature of the radia,to~ wajter a,s well a~ the hot water in the water heater, T~e valYe 5 is controlled by the sensor in order to cont~ol the amount of hot Fxeon (a trademarkl gas flowin~
to the pi~pe coil 8 in the water heater 4 and to the pipe co~l 3 in the heat exchanger 15. Thereby, -the temperature of the hot water of the water heater and the hot water for the radiators ~s controlled. The sensor 17 is connected also w~th the compressor 1 and with a regulator 18 for controlling the feeding of water~to the evaporator 2.
Thus, the compressor 1 and the regulator 18 functions in dependence of the temperature of the hot water of the water heater and the hot water for the radiators, respectively.
In a system according to the invention it is pos-sihle to provide the consumption water with a temperature of 58-65C and the radiator water with a temperature of 50-56~C. By means of the described distribution of the gas supply to the hot water heater and the heat exchanger for the radiators there is provided a more rapid heating of the consumption water.
