The Thermal Insulation Design for Refuge Chamber

Abstract:

For provide outstanding thermal insulation capacity for the refuge chambers, this paper firstly put forward a 5 layer heat insulation structure for refuge chambers. Mineral wool and acrogel were used as the heat insulation materials because of their excellent heat insulation and fire resistance capability. Then the paper determined the thickness of each layer by theoretic analyze using heat transfer theory, and found two 10 mm layers of acrogel and a 62mm layer mineral wool were ideal thickness. Then the paper designed the cooling system, according the heat analysis. And found the ice cake was best fit for refuge chambers, but it must equip with air flue to keep the enclosed air flowing. At last, 8 people were employed in the closed chamber for 106 hours, and raised outside temperature to 55°C for 5 hours. The chambers inside temperature was most controlled under 35°C. Then the paper increased the thickness of acrogel layer according to the experiment results at last. Theory analysis and experiment show that the designed heat insulation structure and cooling system had an excellent thermal protection capability.
