Key Design Features of Forced Draft Cross Flow Cooling Tower
1. Fan Placement & Type:
- Location: At tower sides/bottom, at air entrance points
- Type: Typically centrifugal fans (handle static pressure better)
- Orientation: Blowing inward horizontally
2. Air Flow Pattern:
- Positive pressure inside tower (opposite of induced draft)
- Air enters with higher velocity
- Less uniform distribution potential
3. Plenum Chamber:
- Space between fan discharge and fill media
- Designed to distribute air evenly
- Critical for performance
