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.
