HEATING AND HOT WATER SUPPLY SYSTEM OF FLATS OF MULTI-STORIED BUILDINGS Russian patent published in 2011 - IPC F24D3/08 

FIELD: power industry.

SUBSTANCE: heating and hot water supply system of flats of multi-storied buildings includes cold water supply pipeline, heat supply pipeline having floor taps, and return heat supply pipeline, water heating heat exchanger for hot water supply and temperature control. The new feature is the inside heat supply pipeline there arranged is cold water supply pipeline having floor taps directed to water heating heat exchanger for hot water supply, and then to hot water supply of flats located on the floor; floor taps of heat supply pipeline are divided into two flows one of which is directed for heating of flats on the floor, and the second flow is supplied to heat exchanger for additional water heating for hot water supply; the required temperature is maintained by means of temperature control.

EFFECT: increasing efficiency, reliability and compactness of heating and hot water supply systems by reducing the heat exchange surface of hot water supply heat exchanger and arranging some part of heat exchange surface for preparation of hot water in the pipe of supply pipeline.
