HEAT STATION OF HEATING AND HOT WATER SUPPLY SYSTEM Russian patent published in 2013 - IPC F24D3/08 

FIELD: heating.

SUBSTANCE: heat station of the heating and hot water supply system includes supply and return pipelines of heat network, being supply and return pipelines of the heating system, cold water pipeline and hot water pipeline, heat exchanger - water heater of hot water supply system, crosspiece, check valve, three-way control valve with temperature sensor, which is installed in return heating pipeline; at that, supply and return heating pipelines are connected to heat exchanger - water heater through three-way control valve. Crosspiece is connected to section of return pipeline of the heating system and equipped with a bypass control; check valve is installed on return heating pipeline upstream of three-way control valve; temperature sensor installed on hot water pipeline is used as sensor of three-way control valve, and ratio of diameter of the pipeline connecting the supply heating pipeline to the first input of three-way control valve and return pipeline of heating system, which is connected to the second input of three-way control valve, is within 0.3 ≤ D₁₀/D₂ ≤ 1.3, where D₁₀ - diameter of pipeline connecting the supply heating pipeline to the first input of three-way control valve; D₂ - diameter of return pipeline of heating system, which is connected to the second input of three-way control valve. Plate-type heat exchanger is used as heat exchanger - water heater.

EFFECT: increasing heat output.
