By analyzing the heat transfer process in trombe wall and of air gap, a CFD model for simulating temperature field in trombe wall is presented and solved by coupling the conductive and radiative heat transfer in solid with RNG κ-ε equation. The suitable construction and material were given by analyzing on the sensitive factors such as material height, thickness and coat material on metal plate. The conclusion drawn in the paper can promote the development of integrative technology for solar and architecture.
