| Abstract: | The heat transfer characteristics of exterior protected construction of environmental test chamber in three different cooling conditions were analyzed through construction of physical and mathematical models under an unsteady state from high temperature to low temperature, and numerical calculations of heat transfer by FVM as well as TDMA. A conception of mass coefficient was put forward to simplify cool consumption calculations of exterior protected construction. |
