Analysis of thermal performance of a new regenerated glass pumice external wall insulation system in hot summer and cold winter zone

摘要

The thermal performance of a new regenerated glass pumice board as external wall thermal insulation material was analyzed in this paper. Considering the roles of solar radiation and air convection, and selecting Wuhan city as an example of the hot summer and cold winter zones, the temperature field distributions of the external building walls in different orientations in summer and winter seasons were numerically simulated by using the finite element software ANSYS. The thermal performance of regenerated glass pumice exterior wall external insulation system including the heat transfer coefficient and the temperature distribution was evaluated. The simulation results demonstrate the good thermal insulation performance of the regenerated glass pumice as a new kind of external wall materials, and the feasibility of the application of this environmentally friendly material to the wall insulation system in energy conservation building is also promoted.
