2 Guide to Evaporative Air Coolers

The performance of evaporative systems deteriorates as the humidity increases.
Consequently, evaporative systems are not suitable for high humid regions. They
are generally suitable for areas with dry summers, although their effectiveness will
be reduced during the occasional periods of humid weather that these areas can
experience.
Evaporative air Coolers not only cool, but also humidify homes. This is why they will
not do you much good if you live in a climate that is already very humid.
Evaporative cooling is not suitable in areas that have both a high temperature and a
high moisture content simultaneously.
Evaporative coolers suit only dry climates where humidity is low. If you live in a very
humid place, your evaporative cooler may not work as effectively as it does in dry
areas.
Using an evaporative air cooler in a humid area causes only a small amount of water
to evaporate, so the cooling ability may be poor. Also, higher humidity level speeds
up corrosion, which in turn causes the parts of the air cooler to deteriorate.
If you live in a region where the summers are hot and dry, a portable evaporative
cooler can be a cheap and effective way to keep you cool over those long sunny
days. However, if you live in a humid area, they will not be the most effective option.
Because evaporative coolers need a constant source of hot dry air to work
effectively, you need to leave a door or window open and position the unit near it.
The open door or window also helps keep down the overall humidity in the room.
The more humid the room, the less effective the cooler.
