SYSTEM FOR CENTRALIZED HEAT SUPPLY OF BUILDING Russian patent published in 2003 - IPC

FIELD: heat and power engineering, namely centralized heat supply systems of residences, municipal and industrial buildings and erections having heat station connected with direct and return main pipelines of centralized system for circulation of heat transfer agent from central boiler room or from central heating plant. SUBSTANCE: system includes direct and return pipelines of heating network creating together with circuits of local heat supply systems of building using high temperature heat transfer agent and having circuit for hot water supply with apparatus for preliminarily heating hot water fed to hydrants; system for circulation of network heat transfer agent. After circuits of local systems using high temperature heat transfer agent before apparatus for preliminarily heating hot water fed to hydrants there is circuit of heating systems using low temperature heat transfer agent, for example heating system with heating devices embedded in floor of rooms. EFFECT: continuously enhanced efficiency of centralized heat supply system, low cost price of heat supply system of building. 1 dwg
