Numerical Simulation and Analysis of Heat Comfortablity on External Wall and Window's Insulating Property

摘要

To study the connection between the insulating property of the external wall or window and the heat comfortability index PMV, a numerical simulation was conducted on a radiator heating room. The results shows that, 1) the heat comfortability index PMV when the heat transfer coefficient of the external window is 6.40w/(m~2·k) and the heat transfer coefficient of the external wall is 1.280, 1.024, 0.768, 0.60, 0.512, 0.390, 0.256 w/(m~2·k) separately, and the curve about the PMV and the heat transfer coefficient of the external wall is obtained; 2) the heat comfortability index PMV when the heat transfer coefficient of the external wall is 2.80w/(m~2·k) and the heat transfer coefficient of the external window is 6.400, 5.120, 3.840, 2.800, 2.560, 2.100, 1.280 w/(m~2·k) separately, and the curve about the PMV and the heat transfer coefficient of the external window is obtained.
