Mathematical model of man-clothings-micro-climate system is built up and the boundary conditions of numerical solution for the model proposed. To evaluate thermal comfort for dressed and undressed body respectively based on SD and EQT indicator, coupled iteration method between three-dimensional Navier-Stokes equations and bio-heat equations is employed. Typical examples show that the numerical results are close to the experimental data both for the dressed and undressed body situation.
