Abstract:

In order to study the influence of the large space and low temperature environment of the indoor ski resort on the design of the smoke prevention and exhaust system and ensure that the smoke prevention system is safe and reliable under the special architectural environmental conditions of the indoor ski resort, and to draw the most suitable smoke prevention design plan, combining actual engineering cases, the paper analyzed the difficulties in the smoke prevention and exhaustion design of indoor ski resort buildings, and employed computer simulation technology to compare and analyze the situations of the smoke spreads under no smoke exhaust facilities, mechanical smoke exhaust systems and natural smoke exhaust systems. According to the simulation results, when the indoor ski resort adopted the mechanical smoke exhaust system, the smoke exhaust effect was best in the case of fire. Therefore, it is recommended that the indoor ski resort should give priority to the mechanical smoke exhaust method.
