How Does It Works??

- Hot water pump in from outside source and sprayed into the tower.

- Wind will moves air in and out of the tower. The tower is designed so that winds blow in horizontally, so the air moves in a crossflow direction. 

- The airflow rates are determine by the wind velocity.

- As the air becomes heated, it will travels up and the cool water will fall down.

- Location of this tower is important because wind velocities of 4.5 to 6.5 mph are required in order for it to function properly.

- These tower have a 30% to 55% efficiency rating for cooling water.

- Very cost effective because the system does not require a fan.

- Efficiency can fluctuate greatly because it depends on an uncontrollable factor (wind velocity).

- Heat transfer drops significantly with the loss of airflow.

Advantages & Disadvantages

• Low power requirement.
• Typically lower initial and long-term cost, mostly due to pump requirements
• Accepts variations in water flow without changing the distribution system
• Easy maintenance access to vital parts.

• Performance varies greatly due to its dependence on wind direction and velocity.
• Moss formation due to water is distributed through open ducts means that sunlight comes into the tower through louvers causing serious biological formation.
• Large air inlet surface makes icing difficult to control
• Tendency of uneven air distribution through the infill due to the large inlet surface
