METHOD OF HEAT SUPPLY 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, namely to independent methods of connecting a heat load, and can be used in heat supply systems. In the heat supply method with independent connection of consumers and one source of heat energy, which includes heating of delivery water, supply of hot delivery water through the supply main pipeline to consumers and return of cooled water through the return main pipeline, in the heating main channel transport zones are arranged with heat insulation on the supply and return main pipelines and heat-insulated zones of heat extraction to consumers, each heat extraction zone is made with possibility of independent connection of at least one consumer of heat load by arrangement of at least one manifold on non-heat-insulated section of supply and/or return main pipelines, thermal installations of each consumer are connected to the consumer heat pump condenser, heat load to consumers is provided by transferring the required amount of heat from the supply main and/or return pipeline from the heat extraction zone in the heat main channel to the intermediate heat carrier in the manifold, intermediate heat carrier is transported to evaporator of heat pump of consumer, at that heat carrier circulating in heat installations of consumer is heated to required temperature in condenser of heat pump and supplied to corresponding heat installations. Heat-insulated zones of heat extraction are organized by means of equipment of internal surfaces of walls of channel of heating main with multilayer heat insulation with heat-reflecting layer from side of channel cavity.

EFFECT: providing hydraulic stability of the heat supply network operating mode and reliability, simplifying the design, adjustment and operation of the heat network, reducing energy consumption for heat carrier pumping, reducing head losses in the pipeline.
