CENTRALIZED HEAT SUPPLY SYSTEM AND METHOD OF ITS OPERATION Russian patent published in 2006 - IPC F24D10/00 F24D19/10 

FIELD: heat supply systems.

SUBSTANCE: invention relates to dispatcher control and servicing of centralized heat supply system with great number of local (peripheral) units. Proposed system contains central heat-generating unit to supply great number of local units with hat primary liquid. Each local unit includes heat exchanger and pipeline network. Pipeline network includes supply pipeline to transfer primary liquid from heat-generating unit into each local unit. Each local unit is connected with supply pipeline and is made for receiving primary liquid through primary side of heat exchanger designed to transfer heat of secondary liquid which flows through secondary side of heat exchanger. Each local unit includes first devices made for obtaining at least one primary parameter which is related with efficiency of heat transfer. Each local unit includes first communication device which is made for transmission of instantaneous value of first parameter into second device of communication system. System includes second devices interacting with second communication device and made for revealing local unit servicing of which is most required depending on instantaneous value of first parameter.

EFFECT: improved checking of efficiency of centralized heat supply system.
