Abstract:

To solve the hydraulic maladjustment problem of a district heating system, the fluid network analysis method was adopted to establish a mathematic model of a hydraulic operating mode for a district heating system. The solution algorithm of the mathematic model was given. In addition, simulation regulation software was developed by network developing language JAVA according to the simulation analysis method. This software was developed for a specific real case. Then a new method was provided to effectively solve hydraulic maladjusted problems of a district heating system.

Key words: district heating system; hydraulic adjustment; simulation analysis method; mathematic model
