玻化微珠保温混凝土墙体温度场数值模拟与分析

In order to compare the heat transfer performances of the normal concrete wall combining with thermal insulation layer, with the normal concrete wall and the glazed hollow bead insulation concrete wall, it had been analyzed by using ANSYS that the internal steady-state temperature field distributions of three different walls in extreme weather conditions and their change laws of transient temperature field with time after indoor air-conditioning equipment was closing in this research. The analysis results were also compared with the measured results. The results showed that the simulation analysis values and the measured ones were in good conformity. The heat preservation effect of glazed hollow bead insulation concrete was close to normal concrete combining with external thermal insulation layer. The heat insulation effect of glazed hollow bead insulation concrete was better than that of normal concrete when it was served as building envelope.
