Data Center Lithium-Ion UPS Room Explosion Modeling

Coffman provided explosion engineering and modeling services to facilitate the installation of multiple lithium-ion powered UPS backup power systems at a multistory data center. Explosion prevention system designs were developed for the building’s 18 UPS rooms.

Explosion prevention system designs were supported with CFD modeling to determine the minimum ventilation exhaust rates and the maximum overpressure that may result from a partial volume deflagration within the protected spaces. Modeling efforts utilized FLACS explosion and gas dispersion modeling software and FDS fire modeling software. Modeling investigated multiple fire related and non-fire related thermal runaway scenarios.
