ADIABATIC FLUID COOLERS AND CONDENSERS: IMPACT OF PAD SYSTEM DESIGN ON SATURATION EFFICIENCY _AND UNIT OPERATION_

摘要

1. What are adiabatic pads and what do they do?2. What variables affect adiabatic pad performance?3. Is saturation efficiency all that matters to adiabatic fluid cooler or adiabatic condenser thermal capability? Closed circuit coolers and refrigerant condensers which utilize air-cooled heat exchange are growing in popularity for various reasons, but mainly to conserve water. However, in climates with high ambient temperatures, air-cooled heat exchangers require too much capital cost, consume too much energy and/or require too much plan area. In many cases, incorporating adiabatic pads on an air-cooled heat exchanger (a.k.a., an adiabatic fluid cooler or refrigerant condenser) is the best solution to balance costs, energy consumption and the size or number of units required.
