Abstract: |
According to the boundary conditions of the composite wall under periodic outdoor temperatures, calculation formula of one dimensional nonsteady heat conduction governing equations was established for its inner surface temperature. Combined with the compound wall structure characteristics and the summer weather data for the hot summer and warm winter area, characteristics of inner surface temperature response and change rules for different orientation of all kinds of composite walls along with the change of outdoor temperatures was analyzed. The study results could provide the guidance for composite wall on heat insulation and the indoor comfort. |
