CENTRALISED HEAT AND WATER SUPPLY SYSTEM Russian patent published in 2011 - IPC F24D11/02 

FIELD: power industry.

SUBSTANCE: centralised heat and water supply system includes steam-compression heat pump plants with electric drive, which have the substance with low critical parametres, e.g. carbon dioxide as working medium of thermodynamic Lorentz cycle, main heat pipelines supplying the heated system water to the city and intracity systems and devices using heat and chemically treated water for city needs. Waste river water of hydro-electric power station turbines, which has increased temperature potential, is used as low-potential heat source for heat pump plants (HPP), and water from the same source is used as system water heated at HPP.

EFFECT: improvement of ecology owing to displacement of heat sources and reduction of river water evaporation, as well as improvement of economic properties of HEPS-HPP system owing to additional sale of heat and chemically treated water, which in general will also contribute to improvement of hydraulic power development image.
