Smoke Control System

Fire prevention system of subway station plays an important role in ensuring passenger safety. The Shenyang Youth Street subway station fire prevention system safety was studied, applying performance-based fire protection design analysis method, using of FDS simulation software on the station fire prevention safety system for the calculation and analysis. Three working conditions were set when subway fire happens. Fire smoke flow characteristics and the distribution of temperature, CO concentration and visibility were analyzed and compared. The results show that the automatic sprinkler system and smoke control system have great effect on the preventing spread of fire. In the automatic sprinkler system and smoke control system conditions, fire hazards have not reached the standards of passengers tolerance.

A smoke exhaust system must be installed basically in all high-rise buildings in Japan, in order to eliminate smoke and gas from combustible materials and ensure safe evacuation effectively. However, a new problem, i.e., the difficulty of opening and closing doors when a smoke exhaust fan is operating, has occurred since air-tightness has been improved in high-rise buildings. There are therefore many cases recently where a pressurized smoke control system is adopted. In this paper, the basic concept of this system is described and the pressurized smoke control system that is used in Harumi Triton Square, one of the largest high-rise buildings in Japan.

Smoke Control System

The fire simulation technology is widely used with the rapid development of computer technology. Taking a 12-story building for calculation, numerical simulation method is used to analyze the wind speed distribution characteristics of opening stairwell door and lobby door under different air supply volume. Then the appropriate pressurized air supply mode and back pressure coefficient value under natural smoke venting have been recommended. The researches show that computer simulation can be used in smoke control system design to help determine pressurized air supply mode and design parameters, so as to solve difficult problems in engineering design.
