Description

HEAT SUPPLY SYSTEM

The inventive utility model relates to the field of heat supply and can be used in heating systems of residential, administrative and industrial buildings.

A known heat supply system 1, comprising supply and return pipelines connected to a heat source and to a heating system, a regulator with a sensing element mounted on the supply piping. To increase the efficiency of heat removal, the system is equipped with a heat pipe, the evaporation part of which is mounted in the return pipe, and the condenser part is located outside the building, and the sensitive element is located on the heat pipe.

The disadvantage of such a heat supply system is its complexity.

A heat supply system 2 is also known, which contains a heat source with supply and exhaust pipes, heating devices with supply and exhaust pipelines, a heat accumulator filled with an intermediate heat carrier, and heat pipes for charging and discharging a thermosiphon type connected to it, a circulation pump. In this system, to increase the efficiency of heat removal, the heat accumulator is connected parallel to the supply pipe using two bypass lines, to which, respectively, heat pipes for charging and discharging are connected, and the substance with a phase transition serves as an intermediate heat carrier.

The disadvantage of the system is its complexity and insufficiently effective heat removal.

A centralized heat supply system 3 is also known, comprising a supply and return lines, in which an increase in heat removal efficiency is achieved by installing a heat pump with a condenser and an evaporator, while the output of the condenser on the heating side is connected in series with the said condenser of the steam turbine drive of the compressor and with the supply line between the steam generator and the peak boiler room.

The disadvantage of the system is its complexity and insufficiently effective heat removal.

Closest to the claimed is a heat supply system 4, including main pipelines of centralized heating, additionally containing a heat pump installed with the ability to connect both to the main pipeline with heated water and to the main pipeline with cold water. Depending on the season, the heat pump is used either to heat the water in the supply pipe or to lower the temperature of the water in the return pipe.

The disadvantage is the complexity and cumbersomeness of the system, as well as the inability to use a structurally simple, and therefore cheap heat pump with a low temperature gradient and the associated problems in the design, installation and operation.

The purpose of the proposed technical solution is to maximize the efficiency of heat removal of existing and newly designed heat supply systems, moreover, in the simplest and cheapest way.

pipeline "refrigerator - to the return pipe, and" a heater to the contour of the mixture.

In FIG. 1 presents the inventive heating system, where:

1- direct pipeline from the network;

2- knot mix;

3- direct pipeline heating branch;

4- re-circulation contour of the mixture;

5- return pipeline heating branch;

6- heat pump refrigerator;

7- heat pump heater;

8- heat consumer.

The heat supply system works as follows: the coolant flows through the straight pipe 1 to the mixing unit 2. In the mixing unit, the incoming heating medium is mixed with the heating medium from the recirculation circuit of the mixing 4 of the return pipe, after which it enters the heating branch 3. The heating medium from the heating branch 5 split into two streams. One enters the recirculation circuit of the mix 4, the other enters the external network. The heat pump transfers unused thermal energy from the coolant flowing into the external network to the flow of the recirculation mixture circuit. The refrigerator 6 of the heat pump is included in the flow of coolant flowing into the heat network. The heater 7 of the heat pump is included in the recirculation mixture. Due to this inclusion, it is possible to transfer thermal energy through the heat pump at a relatively small temperature gradient created by the heat pump.

The inventive heat supply system allows simple means to provide high performance in terms of heat removal, easy to manufacture.
