Abstract

Use: heating and hot water for individual houses and apartments. Purpose: reducing the time for heating a heated water supply. The essence of the invention: the system contains a heating unit (OA) 1, a capacitive heat exchanger 2 with a flow-through coil 3 for hot water supply, the main station (HS) 4, an additional heat exchanger (DT) 5 type pipe in the pipe, a heating device 8, pipelines 9 , 10, 11, 17. 19. When cold water is supplied for hot water supply in the DT 5 and HS 4 zones, a low temperature water column is formed, which automatically turns off the water circulation in the heating system, which directs all hot water from OA 1 to DT 5. At the same time, the time for water heating is reduced and the convenience Use hot water when doing sanitary and household supplies. 1 il.

Description

cl

sanitary water to the required temperature by passing it through complex pumping systems through several heat exchange steps causes a considerable duration of heating water for hot water.

The heat supply system is also known, x: a heating unit connected to it through a capacitive heat exchanger with a flow coil for hot water supply, a main stand, a heating device, a supply line connected to the main stand, and a return pipe from the heating system.

The disadvantage of this system is the impossibility of using all the heat received from the heating unit to heat water for hot water supply and, as a result, a long period of time required to heat water for domestic needs.

The aim of the invention is to reduce the time required to heat water for hot water supply.

This goal is achieved due to the fact that the known heat supply system is additionally equipped with a heat exchanger such as a pipe in a pipe installed on the main stand, and heated water in series with a flow-through serpentine of the capacitive heat exchanger.

When hot water is used for household needs, cold water enters the additional heat exchanger, as a result of which a water seal is formed in the area of the additional heat exchanger and the main drain because of a decrease in water temperature and the water circulation in the heating system stops. The hot water coming from the heating unit circulates only through the capacitive heat exchanger and, thus, the full capacity of the burner unit is used to heat the water for the hot water supply passing through the flow-through coil, as a result of which the time needed for heating water for household needs is significantly reduced.

The drawing shows schematically the heat supply system.

The heat supply system consists of a heating unit 1, a capacitive heat exchanger 2 with a flow-through coil 3 for supplying water, a main drain 4, an additional heat exchanger 5 consisting of pipe 6 and pipe 7 located in it, heating device 8, feed pipe 9 connected to the main drain and return pipe 10 to the heating system pipeline 11.

The water supply to the hot water supply is carried out through the pipe 12 pipe b and

the outlet of the pipe 13 of this pipe, connected to the inlet of the 14 flow coil. The heated water is drained through the choke 15 of the flow coil. Capacitive heat exchanger has three

0 fittings located at different heights. The lower fitting 16 is connected to the return pipe 17 of the heating system. The middle fitting 18 is connected to the pipeline 19, through which heating water from the heating unit, the passage through the capacitive heat exchanger, is fed into the heating system through its upper fitting 20 connected to the main drain. The system works as follows.

In the initial position, the water in the capacitive heat exchanger 2 is heated, so the water is heated in the heating unit 1, through line 19, entering the capacitive heat exchanger 2 and not cooling (its outer walls are insulated), through the upper fitting 20 enters the main one to 4, and then into the heating device 8. The hot water entering the heating device 8 through the supply pipe 9, during system operation, returns through the return pipe 10 through pipe 11 to the heating unit 1, is continuously cooled. Due to the difference in water temperature and, as a result, the difference in its specific gravity

5 it is circulated by the heating unit 1 — the heating device 8, the heating unit 1. In the drawing, the path of this circulation is shown by a solid arrow.

0 When the system operates in the hot water supply mode, cold water flows through fitting 12 into pipe 6 of the heat exchanger 5, a pipe in the pipe, and taking heat from the water in the pipe 7 of the heat exchanger 5, through fitting 13 enters the flow coil 3, where it is finally heated from hot water in the capacitive heat exchanger 2, and through the nozzle 15 enters the water distribution. In this case, in the area of the additional heat exchanger 5 and the main drain 4, a column of water with a lower temperature is formed and, as a result, the circulation in the heating system is automatically shut off. In it

5 time, the water in the capacitive heat exchanger 2 as the water goes to the hot water supply will cool down and through the nozzle 16 will flow into the return pipe 17 of the heating system and then into the heating unit 1. Circulation begins

water according to the scheme heating unit 1 capacitive heat exchanger 2 with flow-through coil 3 - heating unit 1. In the drawing, the path of this circulation is indicated by a dotted arrow.

In this case, all water heated in the heating unit 1 will be used to heat the water going to the hot water supply, due to which the heating time will be significantly reduced.

When it stops using hot water, the water in the capacitive heat exchanger 2 heats up, the water in the main stand 4 warms up, and the circulation of water in the heating system automatically restores the heating unit 1 - heating device 8 - heating unit 1.

The use of the invention makes it possible to shorten the heating time of water for domestic needs, all other things being equal, the operation of the heat supply system (water heating temperature in the heating grid. At. The radiation surface of the heating system, the heating output of the heating unit) and thereby increasing the convenience

It contains the direct and return pipelines of the heat network, the direct and reverse pipelines of the heating system, and the mixer. The latter is installed in the return pipeline of the heating network and is connected with a jumper to the return pipeline of the heating system. Heat exchange stages with heating and heated sides are successively inserted last into the direct line of hot water; The first heat exchange stage is included by the heating side in the lintel, and the heated one - in the split between additional heat exchange step and the second heat exchange step. The system provides heating of water to the temperature required in the hot water supply system, however, improves the heating system operation during the warmest period of the heating season by connecting the water supply to one of the heat exchange levels installed on the straight heating system pipe after the mixer, which contributes to a deeper decrease in the temperature of the water entering the heating system. However, ensuring that the water is heated to the temperature required in the hot water supply system is achieved by the complex system of connecting several heat exchange steps to the hot water supply line.
