Induced Draft Cross Flow Cooling Tower
An Induced Draft Cross Flow Cooling Tower is the most common configuration of crossflow design, where a fan at the top creates negative pressure to draw air horizontally across falling water, producing perpendicular air-water contact for efficient cooling.
Process Flow:
- Hot Water Distribution: Hot water enters open gravity distribution basins on both sides of the tower.
- Water Fall: Water flows downward through metering orifices, falling as sheets or droplets through the fill media.
- Air Induction: Fan at the top creates vacuum/suction, pulling ambient air horizontally inward through inlet louvers.
- Heat Exchange: Air moves perpendicularly across the falling water in the fill section, absorbing heat through evaporative cooling.
- Air Exhaust: Warm, moist air is drawn upward through drift eliminators and discharged vertically by the fan.
- Cool Water Collection: Cooled water collects in the basin for recirculation.
