Important Safety Instructions
The performance of evaporative systems deteriorates as the humidity
increases.
Consequently, evaporative systems are not suitable for the humid
northern, coastal regions of Western Australia. They are generally suitable for
areas with dry summers, such as inland and southern regions (including Perth),
although their effectiveness will be reduced during the occasional periods of
humid weather that these areas can experience
Evaporative air conditioners not only cool, but also humidify homes. This is why
they won’t do you much good if you live in a climate that’s 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.
Evaporative cooling is only suitable for temperatures up to 22 degrees Celsius.
It can also be used in more humid areas up to 25 degrees, (provided it is not as
humid most of the time).
If you live in a region where the summers are hot and dry, such as inland
Australia, 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 won’t 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.
