Abstract

The invention allows to reduce the design water consumption and increase the efficiency of the heat supply system. Heaters (P) hot water supply of the upper and lower stages 7 and 8, respectively. connected to supply and return pipelines (TP) 1 and 2 Acc. according to a mixed scheme. The hot water supply system contains supply and circulation TPs 5 and 6, respectively. and additional П 9, installed on ТП 6 and connected by the heating side, bypassing to supplying ТП 3 of the heating system. If the temperature of the water in the TP 3 is predetermined, the heat supply regulator 10 opens and re-supplies the network water through P 9, in which the water from TP 6 is cooled, which allows reducing the flow of system water at P stage 7 and acc. in the heat network. 1 il.

; This invention relates to District Heating Systems.

The purpose of the invention is to reduce the consumption of water and increase the efficiency of the heat supply system.

; The drawing shows the subscriber input scheme of the heat transfer system.

Subscriber input contains supply 1 and return 2 pipelines of the heat supply system, supplying 3 and onboard 4 pipelines of the heating system, supplying 5 and circulating (pipelines of the hot water supply system, heaters of the upper and lower 8 stages of the hot water supply, additional the heater 9, the heat supply controller 10, the controller 11, the temperature is hot.

Subscriber input heating system works as follows.

The mains water through the supply pipe: the pipe 1 of the heat supply system enters the subscriber input, where part (e through temperature controller 11 and: upper stage 7 after mixing with (Ebrative water from return pipe A of the heating system and lower stage 8) returns to the return pipe 2 heat supply systems (the other part enters through the pipeline; 5U 3 into the heating system, I When the water temperature in the supply pipe 3 of the heating system exceeds the value specified for a given outdoor temperature, the regulator 10

The heat supply is opened and the network water is bypassed through an additional heater 9, in which it is cooled by water from the hot water supply circuit A. The presence of an additional heater 9 on the circulation pipe. E 6, connected by heating side bypass to the supply pipe 3 of the heating system, reduces the consumption of supply water on the heater of the upper stage 7 and, accordingly, in the heating network.

 The most effective use of subscriber input during periods of cutting temperature schedule.
