Abstract:

In recent years, there are frequent failures in domestic heating systems. It brings not only economic losses, but also social impacts. The construction of domestic heating network has developed rapidly since the 1990s. Many systems that have been around for 20 years and are in a high accidental rate period. Based on the investigation of the actual working state of pipe network, it analyzes the variation law of parameters during the heat medium leakage, and proposes a network leakage evaluation system based on the upload parameters. It gives corresponding suggestions for different evaluation results.
