The ventilation of enclosed or underground car parks fulfills two key requirements: remove the pollutants emitted by cars and, in the event of a fire, control the hot fumes and gases produced by the fire, protecting the escape routes and easing access for the emergency teams.
The fully integrated JET FAN system developed by DYNAIR® includes three ventilation elements, some CO (carbon monoxide) detection sensors, a control panel and a CFD analysis: these are the essential requirements to design the most suitable ventilation system for a specific car park.
The system is based on placing a set of axial impulse fans (JET FANS) all along the parking area, which operate in a similar way to a ducted system: when installed on the ceiling, they move the air from the top layers to the bottom layers towards the exhaust areas; by effectively creating a continuous air flow, the JET FANS are able to thoroughly cleanse the air at the bottom and the top layers of the car park, avoiding the creation of areas where air gets trapped.
Jet Fans System is completed by air inlet devices operated by natural air or mechanical devices (parking access ramp, natural ventilation ducts, side openings or inlet fans) and exhaust fans.
