Relationship between Designed Fire and Performance of Smoke-Control System in a Living Room

The effects of the size a designed fire on ventilation system an adjacent zone is estimated in this study based visibility requirement 5 m non-fire at 600 s after ignition. To verify adequacy dynamics simulator (FDS) input file, smoke movement and ceiling temperature under hot test conditions AS4391-1999 were compared with those from FDS results. average temperatures measured 12 locations within range ± 2σ, exception one point, predicted adequately. was analyzed terms air volume NFSC 501 for heat release rate (HRR) 1650 kW (air supply exhaust 45,000 cubic meters per hour (CMH)) as well HRR 1100 35,606 CMH 32,506 CMH). It determined that major factors influencing required safety egress time mixture downdraft airflow diffusers layer crossing boundary.
