Cooling Tower BALANCING side Water Flow SLOWER
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
approximately 1% reduction in Compressor Power for each degree that the Condenser Cooling Water Supply Temperature is lowered
Compressor Power reduction would have begun to exceed Propeller Fan power consumption at or below a wet-bulb temperature of approximately 72ยฐF, whereas equality on Blower Fan operation would not have been reached until about 64ยฐF wet bulb.
