HEAT SUPPLY SYSTEM WITH INDEPENDENT CONNECTION OF CONSUMERS AND ONE SOURCE OF HEAT ENERGY Russian patent published in 2024 - IPC F24D11/02 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used in heat supply systems. In heat supply system with independent connection of consumers and one source of heat energy, including heat energy consumers, heat source connected to the supply and return main pipelines of the heat network arranged in the heating main channel, heating main channel contains transport zones with heat insulation on supply and return main pipelines and zones of heat extraction to consumer, made with possibility of independent connection of heat load of at least one consumer, heating main channel walls inner surfaces in each heat extraction zone are equipped with multilayer heat insulation with a heat-reflecting layer on the side of the channel cavity, in each zone of heat extraction, sections of the supply main pipeline and/or return pipeline are made non-heat-insulated, each said non-heat-insulated section of the pipeline is equipped with at least one enveloping manifold with an intermediate heat carrier, wherein manifold ends are connected with heat pump evaporator arranged nearby consumer while consumer heat units are connected with heat pump condenser. Manifold is made of a smooth pipe. Manifold is made in the form of a helical spiral.

EFFECT: creation of a heat supply system with independent connection of consumers and one source of heat energy, providing hydraulic stability of the heat supply network operation mode, reliability and simplification of design, adjustment and operation of heat network, reduction of energy consumption for pumping of heat carrier, reduction of head losses in the pipeline.
