Description

The invention relates to a power system, namely to closed centralized heat supply systems, and can be used in heat points of the systems.

The aim of the invention is to increase the economy and reduce the consumption of network water by using the storage capacity of enclosing structures of heated premises.

The drawing shows a schematic diagram of the substation.

The heat point contains a recuperative heat exchanger 2 installed in the return pipe 1 of the supply water, turned on by the heating path 3 through a three-way valve 4 in the direct pipeline 5 of the supply water, and sections 6 and 7 of the hot water heater, of which the heating side 8 of section 6 is connected to the return the pipeline 1 after the regenerative heat exchanger 2, and the other section 7 of the hot water heater is included by the heating side 9 in the return pipeline 1 of the supply water to the recuperative heat exchanger 2, and the heated side hydrochloric 10 is activated before the first section 6 downstream.

Thermal point works as follows.

The network water through the direct pipeline 5 passes through a three-way valve 4, after which part of the network water in an amount that ensures the temperature of the network water 65-75 ° C in the return pipe 1 after the recuperative heat exchanger 2, is sent to the heating path 3 of the latter, and the rest mains water is mixed with water that has passed through a heat exchanger 2 and enters the heating system. From the heating system is inverse

the net water passes through the heating side 9 of the section 7 of the hot water heater and, after cooling, enters the recuperative heat exchanger 2, where it is heated to a temperature of 65-70 ° C. After the recuperative heat exchanger 2, the return water flows into section 6 of the hot water heater and, after cooling, returns through the return line 1 of the supply water to the heat supply source.

The water from the drinking water pipeline passes successively sections 7 and 6 of the hot water supply heater, heating up from 5 to 60 ° C. I

Consumption of network water in the system

the consumption of mains water is maintained constant and flat to cover the heat load of the heating, and the heat supply is controlled by an increased rate

temperatures.

The thermal point allows to increase the efficiency by using the heat-accumulating ability of the enclosing structures of heated

premises at a constant flow rate of mains water, which at the same time provides for the lagging of the hydraulic stability of the system at any ratio of loads on the hot water supply and heating.

The inclusion of section 7 of the hot water heater in the return pipeline 1 of the network water to the recuperative heat exchanger 2 provides additional cooling of the network water entering the recuperative heat exchanger 2 from the return pipe 1, which in turn allows to increase the temperature of the network water in direct pipeline 5 of the network water.
