Guide to Evaporative Air Coolers
The performance of evaporative systems deteriorates as the humi-
dity 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 cau-
ses 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.
