Replaced 140,000 CFM active built-up fan room located in the penthouse to eliminate the risk of a single fan failure at the hospital which could shut down the entire patient tower.
Updated airside with a FANWALL array, while maintaining 140,000 CFM airflow in the building during the project.
- HVAC FANWALL design: two banks of FANWALL arrays, each five-wide by three-high.
- Redesign of ductwork and plenum walls.
- Relocation of piping to accommodate the new system.
- Relocation of major supply duct serving the birthing center.
- Fabricated and assembled platform in shop to keep on-site welding to a minimum.
- FANWALL arrays were assembled on each side of the existing vane axial fan before it was removed. Each FANWALL array discharges into a common plenum that is ducted to cool or heat the building.
- FANWALL control system integrated into the existing Siemens Talon building automation system.
