Air Intakes and Outlets
Sponsored Links
Intakes
- Intakes should be at least 0.15 m (0.5 ft) above the terrain. In areas with traffic the intake should be at least 5 m (16 ft) above the terrain
- The distance between intake, firewalls and surrounding buildings must be according the rules of the local authorities
- Short cutting intake air with used outlet air must be avoided
- An air intake should be located in a position where the wind influence on the pressure conditions within the system is limited
- Air velocities in the intake openings should not exceed 2.5 m/s (~ 500 ft/min)
Outlets
- Outlets should go direct out in unrestricted area
- Short cuts with intake air, window openings and residence areas must be avoided
- The distance between outlet, firewalls and surrounding buildings must be according the rules of the local authorities
- An air outlet should be located in a position where the wind influence on the pressure conditions within the system is limited
- The air velocity through the outlet should not exceed 3 - 15 m/s (~ 500 - 3000 ft/min)
