Evaporative Cooling

Evaporative cooling is a process that involves evaporating moisture into an air stream in order to lower the air’s temperature. The resulting air stream can be used to cool a building, other air streams, or the components of an air-conditioning system. The lower the relative humidity, the greater the possible cooling effect with the addition of moisture. This technology is a versatile and energy-efficient alternative or adjunct to compressor-based cooling. In favorable climates, which includes most of the western US and other dry-climate areas worldwide, evaporative cooling can meet most or all of a building’:s cooling load using as little as a quarter of the energy of conventional equipment. It can also be cost-effective to implement when integrated with conventional chiller systems. Using evaporative technology can also improve a facility’s load profile because it reduces the load associated with air-conditioning, which often sets demand peaks.
