Monitoring the thermal networks: an overview of promising tools and methods

This article provides a brief overview of the most promising directions of development of high-tech methods for monitoring thermal networks. We consider three technologies that implement contact methods (method of emission of acoustic signals, the method of ultrasonic scan Wavemaker and acoustic emission method), as well as remote method of thermal aerial photography. On the basis of the strengths and weaknesses of each of the search methods of heat leaks, the author prefers the most promising method of monitoring allows us to solve the problem of monitoring the state of urban underground heating networks, clarify or make schemes of their location, as well as receive operational data on the location of anomalies. There is a high performance thermal shooting, its ability to determine not only the fracture isolation and depressurization of the pipeline, but tracking the development of such changes over time.
