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 72°F, whereas equality on Blower Fan operation would not have been reached until about 64°F wet bulb.
