How to design a mechanical smoke exhaust system?
In this study, with the analysis model for such a large space as exhibition hall or conference room in conventional center, design of mechanical smoke exhaust system was conducted based on currently-available design standard which was then followed by numerical analysis of the design using 3D numerical analysis method.
How are smoke reservoirs protected by mechanical exhaust?
1.1echanical Smoke M exhaust The Building Code of Australia (BCA) [1] generally requires large spaces in buildings to be protected by a mechanical smoke exhaust system designed in accordance with the requirements set out in Specification E2.2b of the BCA.
How is smoke generated in a large space?
The volumetric flow rate of smoke generated from the fire in large space often reaches to hundreds of thou- sands CMH because of extended floor height and as it’s more difficult to isolate How to cite this paper: Kim, J.-Y. and Ahn, C.-S. (2017) Design of Mechanical Smoke Exhaust System in Large Space of Convention Center.
What is the building code for smoke reservoirs?
The Building Code of Australia (BCA) requires smoke exhaust systems to be designed such that the smoke layer is contained within the smoke reservoirs.
In this study, with the analysis model for such a large space as exhibition hall or conference room in conventional center, design of mechanical smoke exhaust system was conducted based on currently-available design standard which was then followed by numerical analysis of the design using 3D numerical analysis method.
How much smoke is generated in a large space?
The volumetric flow rate of smoke generated from the fire in large space often reaches to hundreds of thousands CMH because of extended floor height and as it’s more difficult to isolate the smoke to the limited area, comparing to normal-scale building, design and operation of effective smoke control system for large space is more than important.
How are smoke control systems used in high rise buildings?
Conversely, it may be argued that smoke control systems that either pressurize or depressurize part or all of a smoke zone (referred to as on-floor pressurization systems) are of more dubious value in the context of sprinklered fires in high-rise buildings.
Which is the best NFPA for a smoke control system?
NFPA 92 should be the starting point for any smoke control system design, but it’s important to recognize the situations where using only NFPA 92 is inappropriate.
