Topology and simulation of complex spatial heating network

Based on spatial network, a new calculation method is put forward for simulating the hydrodynamic course of multi-heat sources and multi-loops complex heating network. The method can calculate flux assignment and node pressure of heating network under different conditions by counting non-linear equation group according to network inherent parameter, solve the calculation problem of asymmetric network as the result of fault and remedy the shortcoming of the method for planar network. The topology of spatial heating network is described with graph theory, and an applied method for creating relating matrix and basic loop matrix of spatial network is put forward according to information of planar network. The correctness and practicability of the method are validated by an example.
