METHOD OF ON-LINE DETECTION OF DAMAGED NETWORK PIPELINE IN MULTILINE HEATING NETWORKS Russian patent published in 2016 - IPC F17D5/02 

FIELD: heating.

SUBSTANCE: in headers of direct and reverse system water, as well as in all direct and reverse pipelines of heating system under real-time mode the water pressure is monitored using the pressure transmitters, pressure changes with time are analyzed using the controller and PC, analysis results are supplied to Work Station of the heat source operator. At that minimum distance from system water headers to the pressure monitoring points in the pipelines going from the heat source are selected based on the inequality: 2*L_min/c_pw 〉〉 (τ_response+τ_switch.+ τ_contr.+ τ ^PC _), where: C_pw is speed of pressure waves spreading; τ_response is response time of pressure transmitters; τ_switch. is action time of switching devices; τ_contr. is time of data processing by controller; τ^PC is time of data processing and issuing to PC.

EFFECT: reduced heat energy and heating medium losses.
