The coils 4 and 5 are placed in the vortex tube 1, are connected by pipes 6 and 7, 8 and 9 with heating devices 10 and heat exchanger 11, is placed, for example, in building 12 and the coil 13, is placed in the refrigerating chamber 14 forming isolated from each other heating systems, hot water and cooling.

The pump 15 is connected with a direct pipeline 6 and clicks Tim pipeline 7, which coil 16 of the heat exchanger 11 and the heating devices 10 form a closed circulation path, filled with liquid, such as water - heating systems and hot water. The valve 17 is installed after the heater 10 before the return pipe 7, and the valves 18 and 19 are installed before and after the heat exchanger 11, respectively. Cold water in the heat exchanger 11 is supplied through pipe 20, and the hot out of him through the pipeline 21.

Feed line 22 is connected to the return pipe 7 through the valve 23. The controller 24 is connected electrically impulse lines 25 with the temperature sensors 26 and 27 internal and external air, and with the actuator 28, is rigidly connected via a shaft 29 with the regulatory body 30 mounted on the output of heated gas 34 of the vortex tube 1.

The pump 31 is connected with a direct line 8 and the return pipe 9, which coils 5 and 13 form a closed circulation loop filled with a nonfreezing liquid refrigerant, such as antifreeze in the cooling system. Feed pipe 32 through the valve 33 connected to the return line 9.

Developed by the regulator 24, the signal pulse on line 25 is fed to the actuator (motor) 28, which is the rotating shaft 29 will move the regulatory body, the valve 30 to increase the moving stream of hot gas. While the valves 18 and 19 must be closed. Upon reaching the building 12 a predetermined temperature, for example 20°C, the sensor 26 will give a signal to the controller 24, which fixes the body (valve) 30 in position. When warming on the street will take place in the reverse sequence, i.e. body (valve) 30 will cover the hot gas stream. For hot water, close the valve 17 and opening the valves 18 and 19. Hot water pump 15 is pumped through the coil 16 of the heat exchanger 11. Open the valve (not shown) on Tr is beprovide 20 and is temporary parsing heated in the heat exchanger 11 of the water. At the end of use hot water valves 18 and 19 is closed, the valve 17 open. It is possible to keep the valves 18 and 19 in the half-closed state, and therefore in the heat exchanger (capacitive) 11 the water is always hot.

The cooling of the refrigerating chamber 14 is as follows.

Filled through the feed pipe 32 antifreeze system is put into operation by pumping with a pump 31. In the coil 5, the coolant is cooled and direct pipe 8 enters the coil 13 of the refrigerating chamber 14, where the return of the cold. After the coolant in the return line 9 again supplied to the coil 5 for subsequent cooling.

The use of the invention allows to provide heat and hot water to buildings in places of passage of gas pipelines, as well as to store food. Vortex tube as heat and holidayrelated, allows to obtain heat and cold from energy natural gas without combustion.
