Smoke Control System

According to the current China fire protection code, the main hall as a fire compartment and its evacuation distance in this conference center both over the standards. To solve the problems, the performance-based design is put forward in the paper, such as setting up the "Quasi safety zone". For the main hall, 4 fire scenarios have been designed, next simulated and analyzed. According the result, setting fire protection facilities such as mechanical smoke control system, can achieve safety of evacuation.

Smoke Control System

The technical parameters adjustment of smoke control system in a complicated underground commercial zone is studied by numerical simulations. An underground fire model (it encloses a hotel, a supermarket, and a net bar) and five typical fire scenarios are designed. The Fire Dynamic Simulator code is used to investigate the characteristics of fire spread and smoke movement, and obtain the available safety egress times in different fire scenarios. The required safety egress time is calculated based on the data of actual simulation exercises and numerical simulation by Building EXODUS. The simulation results show that, when the smoke exhaust rate is 5.56 cubic meter per second and air low rate reaches 3.89 cubic meter per second simultaneously, the available safety egress time is more than the required safety egress time.

Smoke Control System

For every fire prevention design, ensuring safe evacuation and preventing the fire from spreading are primary considerations. However, actual fire scenarios inevitably involve many uncertainties, such as the fire source location, the heat release rate, the fire growth coefficient and so on, which make it difficult for the traditional fire prevention system to achieve these primary considerations. In this paper, an optimum and intelligent system design was developed using the feedback of real-time fire characteristics based on precise control logic using computational fluid dynamics. The new system can make an intelligent adjustment to adapt the real-time fire and to obtain the best smoke exhaust condition by coupling the smoke control system and a physical boundary. The fire uncertainties were used to validate the system design, based on a conventional composite building containing room, corridor and atrium. The results show that the intelligent system is capable of providing different and reasonable reactions for various fire scenarios and of ensuring the safe evacuation of the building. Some limitations of the system have been improved by incorporating a constraint factor into activation procedures for solving extra-large and ultra-fast fires. In general, this intelligent design proved useful as a smoke control system which could be implemented in many similar buildings.

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.
