The invention relates to heat engineering, in particular for heating the liquid, and can be used in systems of Autonomous water heating residential premises, buildings and structures for various purposes, vehicles, heating water for industrial and domestic use, for heating the drying of agricultural products.

The known device in which thermal energy is generated due to a change in pressure, velocity and volume of the working environment. Among such devices include vortex tube, which is the effect of the Wound - Hilsa (Century A. Martynov, V. M. Brodyansky. What is a vortex tube? - M.: Energy, 1976, S. 6-10, Fig.1-1). In these devices, a gas with a compressor driven in rotation from the drive, compressed and through the cochlea, where it is accelerated to high speeds, is fed tangentially to the inner surface of the cylindrical pipe. In this tube the gas is expanded and divided into two threads - hot (peripheral) and cold (Central or axial).

Hot flow, temperature greater than the temperature of the compressed gas is diverted from the opposite end of the pipe via a regulating valve in the system, the consumer is and, through the hole made in the end of the cochlea, is given in the opposite direction.

Ultimate ease of construction and simplicity of vortex tubes make them indispensable for many applications. However, as sources of thermal energy such pipes are rarely used. This is due to the low efficiency of the vortex tube, in which a large amount of energy expended in compressing the gas in the compressor.

Significantly higher efficiency of the method and of a similar design concept of the device, in which the working medium is liquid, in particular water (Y. S. Potapov, L. P. Fominsk. Vortex energy and cold fusion from the perspective of theory of motion. Chisinau - Odessa, 2000, S. 160-172).

A method of obtaining heat energy, which consists in the fact that the liquid is fed under pressure tangentially into the spiral cyclone-accelerator of the fluid, where the increment its mechanical energy, then the liquid flows in a cylindrical vortex tube, where it is split into two streams - peripheral hot bypass and cold (warm), moving in the Central part of the tube in the opposite direction. Further, these flows are mixed and hot water is supplied to Burebista - vortex heat generator, comprising a housing with a cylindrical part, equipped with a cyclone, the end side of which is connected to the cylindrical part of the body - vortex tube, the opposite end of this pipe is mounted brake unit and the bottom with the outlet that communicates with the outlet pipe. This pipe through the bypass pipe is connected with the outer end of the cyclone, which made the hole coaxially with the cylindrical part of the body.

And yet, in the vortex heat generator heat energy produced is much less than can be obtained at the same cost of electricity in other ways, providing for the production of thermal energy due to a change in pressure, velocity and volume of the working environment.

The present invention is the provision of heating the liquid with significant power savings.

This object is achieved by implementing the proposed method of obtaining thermal energy due to a change in pressure, velocity and volume of the working environment, which use liquid-gas mixture. The liquid using a pump serves under pressure at the entrance of the liquid-gas mixer, which otruba, heated in the process of movement in her liquid-gas mixture is sent to a separator which separates the liquid and gas, the liquid from the separator is directed to heat exchangers and returned to the intake side of the pump, and the gas from the separator is sent to a liquid-gas mixer.

For convenience in operation and reduce the cost of thermal energy generated by the proposed method, as liquid water can be used, and as the gas is air.

Distinctive features of the proposed method allow for heating of the liquid to the desired temperature at a much lower relative cost of electricity compared with the vortex generators.

To achieve the specified technical result is a device that contains a closed loop circulation of the coolant, a pump, a heat source connected to the heat exchange devices.

According to the invention, the heat generator is made in the form of a series set in a closed-loop liquid-gas mixer, the heat-generating pipe and separator, the liquid part of the separator is connected with a heat exchange device, the output of which is connected to the input in on the progress of electricity for heat generation in the proposed device and reducing the length of the heat generating pipe it is mounted sequentially spacers with wedge-shaped edges or tapered holes.

For a split path heat and loop heat on the cage or inside it has a heat exchanger connected to the heat consumers. In this case, the output from the liquid portion of the separator is connected to the intake side of the pump that supplied water to the liquid-gas mixer.

In order to reduce the time required for removal of the device on the current mode of operation, and to compensate for possible small leaks from the gas path in the proposed device has a battery of high pressure air, the liquid portion of which is connected to the output of a pump, a water inlet in the liquid-gas mixer, gas - through the reduction gear is connected to the gas circuit device.

The same result can be achieved if the device is mounted cylinder with compressed gas and a gearbox that is connected to the gas circuit device.

In a device for heat includes a liquid channel, which is a closed path from the input 17 and back 18 pipelines. On line these pipelines are circulating pump 1 with the actuator 2, the liquid-gas mixer 3, the heat-generating pipe 4 with consistently established therein spacers 5, a separator 6 with mounted on it (or in it) heat exchanger 7, the valve 15.

When the pump 1 is designed for high output pressure, heat-generating pipe install spacers 5.

The heat exchanger 7 can not be installed on the separator 6 (or inside it). In this case, the liquid cavity of the separator is connected by a pipe 20 with the entrance to the tract potrebi importername lines in Fig.1.

Gas path feeding the separated gas from the separator 6 in the liquid-gas mixer 3 is also a closed loop consisting of a pipe 19 with the installed orifice 10.

In the case when the gas is air, the device is set for filling and charging circuit battery high pressure air 9, which is connected by pipe 22 located on the valve 12, with the outlet of the pump 1. The output of the air cavity of the battery 9 through the gear 16 is connected by a pipe with the inlet of the liquid-gas mixer 3.

The operation of the device with pre-filled water and gas paths and open valve 11 begins with the start of the motor 2, resulting in a rotation of the pump 1, and, with a gap in time, the opening of the throttle 10. Begins the process of water movement, which is mixed in the liquid-gas mixer 3 with a gas, in particular air coming from the gas cavity of the separator 6. In the process of moving liquid-GeoWAY mixture in the boiler 4 is repeated acceleration and deceleration, followed by heating the mixture.

Getting into the separator 6, the liquid-gas mixture, the result of a sudden the ez path of the heat exchanger 7, fed to the inlet of the pump 1, and the gas via a regulating reactor 10 through pipe 19 is input into the liquid-gas mixer 3. The valve 11 is used to control the flow of water in supply 17 and 18 reverse pipelines, and valve 15 to refuel and recharge the device with water.

The heat from the water and gas is passed from the separator 6 in mounted around (or within) the heat exchanger 7 is connected by a pipe with heat consumers.

To maintain in the gas path of the device high-pressure gas, you can use the battery 9. In this case to turn on the device open the valve 14, indicating the internal cavity of the battery with the atmosphere, and the valve 13, which drain the battery. Furthermore, these valves, and the valve 11 is closed, open the valve 12 and starts the motor 2, resulting in a rotation of the pump 1. Water under pressure flows through the pipe 22 into the battery 9, compressing the air. During operation of the device is automatically recharge its gas path of high pressure air through a specially adjusted the gear 16.

Recharge the gas path can be produced from tradition was an experimental prototype teplogeneratore setup (TSU) using water centrifugal electric pump unit brand pumps 20/35, liquid-gas mixer, the heat-generating pipe of the separator and valve piping. The ratio used lengths teplogeneratory pipe (L) to diameter (d), i.e. L/d was varied in the range from 10 to 30, and the ratio of the mass of gas (Ggto the mass of water (GW) was approximately 0.1.

The installation was designed and was used to study the effectiveness of various gases (air, helium, methane, and others), and to select the optimum ratio L/d in the mode of hot water. Thermal energy losses in the circuit of heat was simulated by discharge from the separator hot water and recharge water cold. The results are shown in Fig.2, in which the abscissa axis represents time in minutes and the ordinate axis is the water temperature at the outlet of the separator. On this figure in the form of curves showing the temperature change at the outlet of the separator for the three modes: the mode of heating of the fluid circuit of the heat source (after filling with cold water) - I, the transition mode - II and the steady-state mode - III. The water temperature in the separator can exceed 100With, since the gas pressure above atmospheric pressure. After leaving the heat on us and - not less than 2.7;

for water-methane mixture is not less than 2,9;

for water-helium mixture is not less than 3,1.
