OPERATING METHOD OF CLOSED HEAT SUPPLY SYSTEM Russian patent published in 2015 - IPC F24D3/08 

FIELD: power industry.

SUBSTANCE: invention relates to heat engineering and can be used in heat supply systems. An operating method of a closed heat supply system, according to which delivery water is supplied to consumers from a heat source to cover heat loads of heating and hot water supply, water for hot water supply is prepared locally at a residential heat station by heating cold water in a hot water supply heater, which differs by the fact that the hot water supply heater is two-stage; with that, the first stage in the flow direction of hot water is connected as to heating medium to a return pipeline of a residential heat supply system, and the second stage in the flow direction of hot water is connected as to heating medium to a supply pipeline of the residential heat supply system; consumption of heating medium through the hot water supply heater is controlled by a control valve as to a pressure pulse in the cold water pipeline.

EFFECT: improvement of quality and operating efficiency of a closed heat supply system owing to using a potential of a return pipeline of a residential heating system for preparation of hot water at a residential heat station.
