The Thermal Insulation Design for Refuge Chamber Wang Cancai1, a, Chang Degong2,b 1School of Polymer Science and Engineering, Qingdao University of Science and technology, Qingdao, China 2College of Electromechanical Engineering, Qingdao University of Science and technology, Qingdao, China accwang517@126.com, bhyg867@163.com Keywords: refuge chamber; thermal insulation; heat transfer; heat radiation Abstract.
Mineral wool and acrogel were used as the heat insulation materials because of their excellent heat insulation and fire resistance capability.
Table.1 Parameters of heat insulation material material density [Kg/m3] Thermal conductivity [W/m·K] Specific heat capacity [J/(kg·K)] Q345 steel 7800 50 480 acrogel 208 0.020 400 Mineral wool 50 0.038 0.22 aluminium silicate 100 0.038 0.2 After selected the materials, the next thing is to determine the dimensions of each layer.
The price of materials is the most important thing that the manufacturer concerns.
