Cooling Tower Energy Trade-off Optimization:
Fans vs. Pump
Propeller Fan vs. Blower Fan
Blower Fans require at least twice the applied horsepower of
Propeller Fans to deliver equivalent air flow
A 10% increase in flow will require about 21% greater pressure. A 10% decrease in flow will decrease the required pressure by about 19%.
Manipulation of air rate (and fan power) is a far more energy-effective means of regulating thermal capacity than control of water rate
