Description

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

A known heat supply system [application No. 2003102574 BIPM No. 30 (Part II), 2004], the operation of which includes heating the network water, supplying hot water through a supply main pipe to a heating system directly connected to the water heating network, and returning chilled water through the return main pipeline, in which the cooled water of the return main pipeline is additionally cooled in the heat pump evaporator, and with the heat taken from the water of the return main pipeline, in the condenser The heat pump heats the water circulating in the heating system.

The disadvantage of the system is its lack of efficiency in heat removal.

A heat supply system is also known [application No. 2003115796 BIPM No. 36 (part III), 2004], containing basic and peak heat sources connected by heat networks to subscribers, in which network heaters of heat-generating turbines of thermal power plants are installed as basic heat sources, as peak heat sources, autonomous heat sources are installed for each of the subscribers. The subscribers have installed heat pumps as autonomous peak heat sources, which are connected on the cold side to the return pipe of the subscriber’s heat network.

The disadvantage of this system is also inefficient heat removal.

A heat consumption system is also known [RF patent No. 2111114 BI No. 30, part 2, 1998], including central heating pipelines, 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 water in the supply pipe or to lower the temperature in the return pipe.

Its disadvantage is the complexity and bulkiness of the system, the impossibility of using a structurally simple, and therefore, cheap heat pump with a low temperature gradient, as well as the additional consumption of electric energy and the associated problems in the design, installation and operation.

Closest to the claimed technical solution is a heat consumption system (patent No. 0069615, application No. 2007130478), which contains the supply and return pipelines with a return water mix and a heat pump with heat exchangers, while the heat pump is installed on the return piping with a refrigerator - to the return piping, and a heater - to the contour of the mix.

The disadvantage of this system is the significant consumption of electrical energy consumed by the heat pump.

The purpose of the proposed technical solution is to maximize the efficiency of heat removal of existing and newly designed heat consumption systems while reducing energy consumption.

The essence of the claimed technical solution lies in the fact that in the known heat consumption system containing the supply and return pipelines with the return water mix and the heat pump installed on the return piping with a refrigerator, to the return piping, and the heater to the mix, the heat pump is a unit thermoelectric plates. Additionally, the heat consumption system is equipped with a second block of thermoelectric plates. Both blocks of plates are connected by electrical conductors in a complex in which one of the blocks is a generator of electricity, and the second is its consumer.

Figure 1 presents the inventive heat consumption system, where:

1 - a block of thermoelectric plates supplying energy (generator part);

2 - heat pump (block of thermoelectric plates), consuming energy;

3 - object of heat consumption;

4 - the supply pipe of the heating system;

5 - return pipe of the heating system;

6 - mix pipe;

7 - electrical conductors;

8 - “hot” side of the block of thermoelectric plates;

9 - the "cold" side of the block of thermoelectric plates;

E (with arrow) is the direction of the heat flux.

The block of thermoelectric plates supplying energy (power generator) and the block of thermoelectric plates consuming energy (heat pump) are connected to each other by electrical conductors and form a single complex.

The inventive heat consumption system works as follows: the heat carrier from the supply pipe enters the high-temperature side of the generator part of the thermoelectric plate assembly 1. The low-temperature side of this heat pump is washed by part of the heat carrier from the return pipe 5, which flows from the heat consumption object and goes to the heating system supply pipe. Due to the thermoelectric effect, an electric voltage arises at the terminals of the generating plates of the heat pump 1, which feeds the heat pump (block of thermoelectric plates) - energy consumer 2. The low-temperature side of the pump - consumer 2 is washed by the heat carrier from the return pipe 5 of the heat consumption system. The high-temperature part is washed by a part of the coolant from the return pipe 5 entering the supply pipe of the heating system. The heat pump 2, consuming electricity, supplies part of the heat energy from the return pipe to the supply pipe of the heating system.

An example of a specific implementation. A heat pump is installed in the individual heat point of the heat consumption object in such a way that its refrigerator is included in the flow of coolant flowing into the heat network, and the heater is in the mix pipe of the heating system. Heat consumption automation controls the heat supply process of the facility. Due to the operation of the heat pump, the temperature of the return water to the heat network decreases by 8 ° С ÷ 20 ° С, which is equivalent to obtaining a temperature gradient on the heat pump of 16 ° С ÷ 40 ° С.

The inventive heat consumption system allows simple means, providing high characteristics for heat removal, significantly reduce energy consumption. The system is not difficult to manufacture and can be implemented in the design and construction of residential and industrial buildings.
