Description

The invention relates to the field of heat power and can be used in heating systems of cities.

Known analogues are heat supply systems containing a heat source connected to a heat consumer by the supply and return pipes of the coolant (see the book by G.N. Delyagin, V.I. Lebedev, B. A. Permyakov “Heat-generating installations”, M., Stroyizdat, 1986 , Fig. 10.2 on p. 406). This analogue is adopted as a prototype.

The disadvantage of analogues and prototype is the reduced efficiency and environmental friendliness of heat supply.

The technical result achieved by the present invention is to increase the efficiency of heat supply due to the utilization of low potential heat and environmental friendliness due to the absence of emissions of harmful substances from the heat source into the atmosphere.

To achieve this result, a heat supply system is proposed that contains a heat source connected to a heat consumer by supply and return pipes of the coolant.

The difference of the claimed system is that a heat carrier supercharger connected to the vortex tube is installed as a heat source, a heat carrier supercharger and a vortex tube with a hot carrier flow pipe exiting from it are included in a heat carrier supply pipe, a vortex pipe cool flow cool pipe is connected to an inlet pipe of a supercharger and with a source of low potential heat.

Installation of a heat carrier as a heat source connected to a vortex tube, inclusion of a heat carrier and a vortex tube in the heat carrier supply pipe with a hot coolant flow pipe coming out of it, connection of a vortex tube coolant coolant pipe to the coolant coolant inlet pipe and a coolant pipe coolant pipe connection pipes with a source of low potential heat can improve the efficiency of heat supply due to utilization of low potential heat by a cold coolant flow leaving the vortex tube and environmental friendliness due to the absence of emissions of harmful substances from the heat source into the atmosphere.

The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by the features of the claimed invention. The definition from the list of identified analogues of the prototype as the closest in the set of essential features of the analogue allowed to identify the set of essential in relation to the technical result of the distinguishing features set forth in the claims.

Therefore, the claimed invention meets the condition of "novelty."

To verify the compliance of the claimed invention with the condition “inventive step”, the applicant conducted an additional search for known solutions in order to identify signs that match the distinctive features of the claimed method from the prototype. The search results showed that the claimed invention does not follow explicitly from the prior art for the specialist, since the influence of the transformations provided for by the essential features of the claimed invention on the achievement of the technical result is not revealed from the prior art determined by the applicant.

In particular, the claimed invention does not provide for the addition of a known agent to any known part attached to it according to known rules to achieve a technical result in respect of which the effect of such additions is established.

Therefore, the claimed invention meets the condition of "inventive step".

Next, we consider the information confirming the possibility of carrying out the invention with obtaining the desired technical result.

The drawing shows a schematic diagram of a heat supply system. The heat supply system contains a vortex tube 1 connected by a pressure pipe 2 to a coolant blower 3. A vortex pipe 1 is connected to a consumer 5 by a hot flow 4 supply pipe, and a cold flow pipe 6 is connected to a suction pipe of a coolant blower 3, to which a consumer is also connected by a return pipe 7. 5. A heat exchanger 8 is included in the cold flow pipe 6, to which a pipe of an external source of low potential heat 9 is connected.

The heating system operates as follows.

The coolant enters the vortex tube 1 through the pressure pipe 2 using the coolant supercharger 3. The hot stream divided into the vortex tube into hot and cold coolant flows through the hot stream 4 to the consumer 5, and the cold stream through the cold stream 6 enters the suction pipe of the supercharger coolant 3, and the coolant coolant stream passes through a heat exchanger 8, into which the coolant of an external source of low potential heat enters through a pipe 9, the heat of a low-grade heat source is most utilized. The coolant cooled by the consumer through the return pipe 7 enters the suction pipe of the coolant blower 3.

Efficiency of heat supply is increased due to the utilization of low-potential heat by a cold coolant flow coming out of the vortex tube, and environmental friendliness of heat supply is increased due to the absence of emissions of harmful substances from the heat source into the atmosphere.

The above information indicates the following conditions are met when using the claimed system:

- a tool embodying the claimed heat supply system is intended for use in industry in the field of heat power;

- for the claimed system in the form as described in the claims, the possibility of its implementation using the means and methods described in the application is confirmed;

- a heat supply system embodying the claimed invention, when implemented, is able to achieve the desired technical result.

Therefore, the claimed invention meets the condition of “industrial applicability”.
