Simulation study of complex spatial heating networks based on impedance identification

Aiming at the characteristic of spatial topological structure of a heating network, adopts the hydrodynamic method for spatial networks to replace the traditional method for planar networks, and develops a simulation calculation model for complex spatial heating networks. Realizes the identification of impedance of pipe networks with genetic algorithm (GA). Presents the related model and steps. The validity and practicability of the method are verified by an example.
