Car Park Ventilation
Natural and mechanical aeration and ventilation
Conventional natural and mechanical ventilation is part of the safety standard for fire protection in car parks, underground garages and tunnels. Colt has redesigned fire protection in car parks and underground garages by using car park ventilation / tunnel ventilation. Tunnel ventilation newly designed.
Car park ventilation - solutions from Colt
Pulse ventilation generates a large air thrust with a high air exit velocity, which transports the smoke in the direction of the smoke and heat exhaust fans. The car park is completely flooded with air in the problem zone so that smoke and fire gases cannot stagnate and form so-called dead corners.
- No ventilation ducts required
- More space for other trades
- Very low overall height
- Free space at head height
- More safety for the fire service
- Easier and faster installation
- More efficient energy consumption
- More space for more parking spaces
Natural garage ventilation
Closed car parks with low traffic volumes must be equipped with natural ventilation openings or air shafts. These must ensure a minimum cross-section per garage parking space and must not exceed a certain distance from each other. They must also be unlockable and distributed over the parking garage in such a way that permanent cross-ventilation is ensured.
Mechanical garage ventilation
If natural ventilation is not possible, a mechanical exhaust air system is used. Mechanical exhaust air systems shall be designed and operated in such a way that no more than 100 ppm carbon monoxide is produced during expected traffic peaks. This requirement (e.g. according to the Bavarian garage regulation GaStellV) is considered to be fulfilled if the exhaust air system is able to discharge at least 6 kbm per hour per square meter of garage floor space in parking garages with little incoming and outgoing traffic and at least 12 kbm per hour in other garages. In the case of a mechanical ventilation concept, at least two fans of the same size must be installed in each case, which together provide the required total volume flow when operated simultaneously. Each fan must have its own electrical circuit and it must be ensured that in the event of failure of one fan, the other system switches on automatically.
