Annotation:

The authors of the article, on the background of the analysis and structuring of the problem and processes of monitoring the technical state of heating networks, made an attempt to formalize the task of their operational states monitoring. The peculiarities of this problem, its substantive formulation and possible approaches to its solution are considered. The literature analysis in the field of modeling dynamic processes of heat and mass transfer in cylindrical pipelines resulted in obtaining an analytical solution of the energy conservation equation for determining the temperature of the heat carrier at any point along the length of the pipeline at any moment of time. The proposed equation can potentially be taken as a basis of a dynamic model of the temperature state of a heating network when monitoring it. The mathematical formalization of the considered problem on the basis of the proposed approach of temperature modes dynamic identification is given.
