The invention relates to a technology for the centralized heat supply of residential and public buildings and is intended for use in open heat supply systems.

The subscriber input of an open heat supply system is known, which contains supply and return pipelines, a hot water supply pipeline, a preheater with feed and discharge pipelines, heated water, an elevator and a temperature controller. The disadvantage of such a subscriber input is overestimated temperature.

water network, water in the temperature range of the tour of the outdoor air, corresponding to the heating season and period, the temperature of the return water network after the heating system is equal to the temperature; jf p required for domestic needs.

The purpose of the invention is to reduce the temperature of the return network water.

This goal is achieved by the fact that the subscriber input of an open heat supply system contains supply and return pipelines, a hot water supply line, a preheater with supply and discharge pipes of heated water, an elevator and a temperature controller, a discharge line connected to a hot water supply line. .

FIG. 1 schematically shows the subscriber input.

Subscriber input includes supplying 1 and 2 return pipelines, pre-included hot water heater 3 with inlet 4 and outlet 5 heated water pipes, temperature controller b, elevator 7, hot water supply pipe 8 and pressure regulator 9 with a pulse se on the return pipe 2.

Equipment subscriber input works as follows.

With an increase (decrease) in the water intake from the return pipeline 2, the water flow through the upstream heater 3 and the series-connected elevator 7 increases (decreases) in proportion to the amount of water intake. At the same time, the temperature of water used for hot water supply is maintained at the required level by means of a temperature controller b, which redistributes the flow of heated water between the heater 3 and the hot water supply pipeline 8.

The pressure regulator 9 with the pulse "To yourself installed on the return pipe 2" prevents the pressure in the heating system from decreasing.

The use of this invention allows to reduce the temperature of the return water of the heat network in the open heat supply system and to reduce the waste of heat.

Claims (1)

SUBSCRIBER INPUT OF THE OPEN HEAT SUPPLY SYSTEM, comprising supply and return pipelines, a hot water supply pipe, an upstream heater with inlet and outlet pipelines of heated water, an elevator and a temperature regulator, characterized in that, in order to reduce the temperature of the return mains water, the outlet pipeline is connected to the pipeline hot water supply.
