What's evaporative cooler?
Evaporative coolers, often called "swamp coolers", are cooling
systems that use only water and a blower to circulate air. When
warm, dry (unsaturated) air is pulled through a watersoaked pad,
water is evaporated and is absorbed as water vapor into the air.
The air is cooled in the process and the humidity is increased. The
evaporator cooling technology is an energy-efficient alternative to
compressor-based cooling. In dry and arid regions, evaporative
cooling can meet most or all building cooling loads using
one-fourth the energy of conventional equipment. It can also be
applied costeffectively when integrated with conventional chiller
systems, which can greatly improve a facility's load profile.
