This invention relates to heating devices and can be used in various industries and everyday life, wherever you need any heating devices, sites, space, or area.

Known heating device comprising a generator of heat energy, the heat transfer system to the consumer, which are interconnected in a closed loop through the supply and return pipes located in this circuit, the network pump and mounted with direct and reverse pipelines at least one recirculation pipe (USSR Author's certificate N 1019180, 1983).

This device does not provide satisfactory fuel economy or other taleesha agent generator of heat in all cases.

The task was to create such a heating device, which would provide increased fuel economy or other taleesha agent generator of heat in most cases used in practice.

This problem was solved by the present invention.

In the heating device containing a generator of heat, the heat transfer system to the consumer, which are interconnected in a closed loop through the supply and return pipes located in this circuit, the network pump and establish the ing direct and return piping at least one recirculation pipe, according to the invention recirculation pipe contains at least one element containing the confuser, diffuser and made between the diffuser and the confuser at least one annular groove.

In one embodiment of the invention, the network pump device includes a pump with a constant flow rate of the fluid.

In this case the heating device may comprise at least two recirculation piping installed with the possibility of pumping fluid in opposite relation to each other directions.

Element of the recirculation pipe can contain 2-7 annular grooves.

The heating device may be configured to control the diameter of the hole for the passage of liquid.

In this embodiment, the heating device as a network pump may be a pump with a constant flow rate of the fluid and the heat transfer system to the consumer in this case contains at least one pump with a controlled flow rate of the fluid.

The heat transfer system may also include at least two parallel spaced lines of heating, each of which contains a pump with a controlled flow rate of the fluid.

In these embodiments perform the heating device may include driving the th block, associated with at least one element selected from the group comprising an element of the recirculation piping with adjustable opening, pumps with controlled flow of the fluid and a device for controlling the generation of heat in the generator of heat.

In another embodiment, the heating device as a network pump may be a pump with a controlled flow rate of the fluid.

In this embodiment, the heating device can be configured to control the diameter of the hole for the passage of liquid.

In this embodiment, the heat transfer system to the user may contain at least one pump with a controlled flow rate of the fluid.

Thus the heat transfer system may include at least two parallel spaced lines of heating, each of which contains a pump with a controlled flow rate of the fluid.

In this embodiment, the heating device may include a control unit associated with at least one element selected from the group comprising an element of the recirculation piping with adjustable opening, pumps with controlled flow of the fluid and a device for controlling the generation of heat in the generator of heat.

The heating of the mouth of austo may contain mounted parallel to the pipe recycling drop-in heat exchanger, contains two inputs and two outputs, the inputs are located on the lower end of the heat exchanger, and exits from the top end, with one input and one output connected to the supply piping, and other input and output with reverse pipeline, these inputs and outputs are tangent to the inner surface of the heat exchanger.

In this embodiment, the mixtures, the heat exchanger is preferably cylindrical.

Element of the recirculation pipe containing the confuser, diffuser and made between the diffuser and the confuser at least one annular groove, with the passing of the recirculated fluid, as was shown when the test leads to the production of heat, for example, by creating a specific eddy flow, structural phase transitions, and other possible factors. In this case, as has been shown, it is the implementation element of the recirculation pipe is optimal from the point of view of most economic redistribution of heat flow in the circuit. This ultimately leads to increased fuel economy, or other taleesha substances.

In addition, by reducing the flow resistance of the liquid in the generator of heat (e.g. steam boiler, using a narrow tube, which creates high resistance flux is in fluid) due to the flow of the liquids bypass the generator thermal energy decreases the cost of electricity, used by the network pump for pumping fluid or other fluid in the circuit.

As the pump power is expedient to use a pump with a constant flow rate of the fluid, such as a conventional centrifugal pump. This is because the use of the pump with a controlled flow rate of the fluid requires a relatively expensive control electronics.

However, if possible you can also use the pump with a controlled flow rate of the fluid.

If the heat transfer system includes at least two recirculation piping with a possible transfer fluid in the opposite direction, this leads to lower soprotivlenie thread on the site location systems transfer heat to the consumer and to further optimize power consumption.

The above line element recycling works most effectively if the given element contains 2-7 ring convoc.

To further optimize the redistribution of heat flow heating device operates to control the diameter of the hole adventures fluid, such as holes, in the above line element recycling. Regulation can be carried out by known means, for example, using the pushing of the diaphragm is we.

If in this embodiment, the heating device comprises a network pump with a constant flow rate of the fluid, the heat transfer system to the consumer in this case may contain at least one pump with a controlled flow rate. This allows you to adjust the heat transfer to the consumer and, consequently, leads to fuel economy (fuel agent).

In these embodiments perform the heating device may include a control unit associated with at least one element selected from the group comprising an element of the recirculation piping with adjustable opening, pumps with controlled flow and a device for controlling the generation of heat in the generator of heat. This allows the automatic adjustment of the parameters of the heating device and heat settings to achieve the best fuel economy, or other heat-generating agent, including adjustments to compensate for changes related to the diurnal temperature variation.

Additional optimization of fuel consumption and transfers heat fluxes in a variant implementation of the device in which parallel piping recirculation has mixed exchanger containing two inputs and two outputs, the inputs are the lower end of the heat exchanger, and exits from the top end, with one input and one output connected to the supply piping, and other input and output with reverse pipeline, these inputs and outputs are tangent to the inner surface of the heat exchanger. In this embodiment, the “very hot” fluid delivery pipe is mixed with cold liquid return pipe, after heat exchange in the circuit served optimally heated water, and a generator of heat - warmer, which saves on fuel consumption.

Important to achieve these objectives is a method of operating the above-described heating device. Known devices of similar purpose (for example, patent of Russia №2096695, 1997), designed to work in cavitation mode of the pumping fluid. However, as has been shown, this mode is not optimal for solving the problem of the cost of fuel consumed. In addition, it is known (“Cavitation tunnel,” and ACI, Izd-vo “Shipbuilding”, L., 1972, p.5-23) (1), working in the cavitation device are noisy, have a relatively high level of vibration, quickly destroyed. Therefore, the proposed method of operating a heating device, which includes pumping fluid in the circuit, this transfer is performed under pressure, excluding the occurrence of cavitation in the flow of coolant. The flow parameters are selected according to the recommendations described in (1).
