HEAT SUPPLY SYSTEM Russian patent published in 2019 - IPC F24D3/00 

FIELD: power engineering.

SUBSTANCE: invention relates to heat engineering and can be used for dependent connection of heat consumption systems with possibility of pulse and pulsating circulation of heat carrier in separate sections of heat consumption system. Heat supply system includes a heat source connected to the supply and return pipelines of the heat network, a network pump installed on the return pipeline of the heat network, heat consumption system with distributing feed and return pipelines connected to heat network, impact unit installed in supply pipeline of heat network, check valve. Besides, it comprises three hydraulic accumulators, pressure regulator and additional heat load zone with distributing feed and return pipelines. Check valve is connected to the input of the impact unit and is connected to the first hydraulic accumulator. Second and third hydraulic accumulators are connected to pump inlet and outlet. Supply pipeline of the additional zone of heat load is connected through the first hydraulic accumulator to the check valve, and the return pipeline of the additional zone of heat load is connected through the pressure regulator to the return pipeline of the heat network.

EFFECT: invention allows designing a heat supply system structure for dependent connection of consumers to a heat network by a dependent circuit with the possibility of arrangement of pulsed and pulsating circulation of heat carrier at separate sections of the heat consumption system.
