Test box: The experimental device should be a self-standing box with a width of 1000mm, a depth of 2000mm and a height of 4000mm. The bottom of the box should be 300mm above the ground. The perimeter of the test chamber should be sealed, the air from the bottom of the chamber from the front wall (150±10) mm to open a (800±20) mm x (400±10) mm air inlet into the box. A (300±30) mm x (1000±100) mm outlet should be opened at the back of the top of the chamber. Test chamber should be used on both sides of the heat transfer coefficient of about 0.7W.m-2.K-1 thermal insulation, the distance between the steel ladder and the back wall of the test chamber is (150±10) mm, and the bottom rung of the steel ladder is (400±5) mm from the ground.
