CONTROL METHOD OF SINGLE-PIPE HEAT SUPPLY SYSTEM Russian patent published in 2013 - IPC F24D3/00 

FIELD: heating.

SUBSTANCE: method relates to control of heat carrier temperature in response to changes of external parameters (temperature) and flow rate in response to changes of heat carrier temperature in return pipeline. Control method of the system containing the set of heat exchange units (6) connected in series so that return pipeline (4) of one heat exchange unit (6) is supply pipeline (3) of the next heat exchange unit (6); main supply line (1) connected to supply pipeline (3) of the first one if to look in the flow direction from heat exchange units (6); main return pipeline (2) connected to return pipeline (3) of the last one (if to look in the flow direction) from heat exchange units (6); at which the heat carrier with supply temperature is supplied with certain flow rate from main supply pipeline (1) to the set of heat exchange units (6); in which the supply temperature is controlled in compliance with the supply temperature set point depending on parameters that are external in relation to system of parameters, and flow rate is controlled in compliance with the temperature set point in return pipeline depending on downstream heat carrier temperature from the first unit (6) of the set of heat exchange units.

EFFECT: improvement of the system control is provided.
