Underground parking lots are overwhelmingly designed for offices, shopping malls and high-rise residential buildings. A basic underground car park offers acceptable climate conditions; the more advanced projects include security systems, sound silencing systems and many more. A car park ventilation system is an integral part of any parking lot, integrated in all the underground projects by default.
The minimum temperature in the car park area should not fall below +5°C. Thus, building experts practice integrating systems with air heating mechanisms on board: therefore, the exhaust chambers and recuperators may be installed.
Unlike private garages system, an underground ventilation complex utilises mechanical (artificial) motivation, natural ventilation and mixed forms (mechanical + natural). A solid parking ventilation business integrates the above-mentioned types to guarantee optima ventilation functioning.
Apart from air processing units a decent underground ventilation system includes the elements of smoke removal and even detection. Therefore, the industrial fans and smoke valves are mounted in large ventilation systems.
Ventilation capacity calculation
When designing embedded in the building or detached parking lots of motorized or stationary type, ventilation experts bear in mind the following requirements:
- Autonomy – the ventilation system of underground parking should be implemented independently from the general ventilation complex of the building.
- Automation – the supply and exhaust equipment should function automatically (if e.g. exposure limits are exceeded) along the perimeter of the car park.
- Powerful ventilation, achieved through installation of industrial fans large steel ducts and vents.
- Smoke removal mechanisms should be set in place.
