Thermal condition calculation model of direct connection hot water heating system based on graph theory

To solve the problem of thermal maladjustment of central heating network and analyse the regularity and characteristics of thermal condition changes caused by the changes of thermal network local conditions, based on the graph theory, obtains an uniform calculation model of the thermal condition of heating networks with different geometric structures using the space network topological structure. Calculates and analyses the thermodynamic parameters using this model for the heating network with varying condition.
