Abstract:

This experiment uses polystyrene cystosepiment and the straw board composite as the core board of wall material. Simulated using the ANSYS finite element software the quantity of heat when it transmits from the room to outdoor through the core board material under the winter condition. Analyses through a single-factor when P,S changes respectively, the temperature distribution, thermal conductivity and heat flux of type1,type 2 and type 3 ; Through four factors seven levels of uniform experiment, when P and S change at the same time, the insulation properties of type 2 and type 3 composite material are similar; and predict the thermal insulation properties of composite materials. The actual test results of straw/PS composite is the heat resistance of type 1 is 0.20 m²·(K·W^-1 ), type 2 and type 3 is 1.13 m²·(K·W^-1), and the same as the results of finite element analysis,so ANSYS can be used in heat preservation performance simulation analysis of polystyrene cystosepiment and straw board lamination compound materials.
