SYSTEM OF HEAT AND WATER SUPPLY Russian patent published in 2010 - IPC F24D11/00 

FIELD: power industry.

SUBSTANCE: system of one-pipe heat and water supply consists of basic heat source, of heat main supplying hot delivery water into serviced city and inter-city systems, and of installations utilising heat and delivery water for urban needs. The system consists of three circuits of: high-, medium and low temperature heat carrier connected between them in such way, that delivery water form the high temperature circuit is partially utilised for industry needs and as a heating carrier to city CHP (central heating points); upon cooling in those it is supplied to an average temperature circuit. In its turn this circuit is the source of low potential heat for heat pumping stations supplying heat to its group of city consumers so, that delivery water cooled in evaporators of heat pumping installations -HPI- flows into the low temperature circuit, wherefrom cooled delivery water is supplied into a city system of sweet water production and to technical needs of city.

EFFECT: increased reliability of heat supply.
