Based on the discussion of the principle of thermoelectric simulation, this paper discusses the electrolytic cell method, the conductive method and the network method respectively. In addition, the fabrication of resistive network model, the processing of boundary conditions and the implementation of network method in undergraduate teaching experiment are introduced in detail. This paper points out that when using a resistance network to simulate the wall of a building, the thermal equilibrium error of experimentally measured heat dissipation is only 2 %, The maximum deviation between the node temperature values obtained by experimental and computer numerical solutions is ± 0.09. The network method has the advantages of convenient simulation test, reliable data and intuitionistic effect, and is very suitable for teaching experiments.
