An evaporative cooler also called a swamp
cooler uses water to cool the air, drawing in warm air, which is
then cooled through evaporation before being recirculated into the
room. Using evaporation, swamp coolers can cool the air by as much
as 20 degrees and, when used together with a ceiling fan, can provide
significant cooling effects. Evaporative units consist of huge fans
housed by wet pad covered walls. In this way, these coolers provide
a humidifying function in addition to cooling and are therefore
more effective in dry, arid climates.
You may want to buy a swamp cooler if you live
in an area that has a very dry climate. You can shop online for
evaporative coolers, to compare prices and features. You may also
discuss different evaporative cooling options with the salesperson
in your local store, who may be able to sell you a unit at a great
deal, depending on the time of year.
A homeowner should keep in mind that swamp coolers
tend to require lower maintenance and less energy than refrigerant-based
cooling units. A homeowner should keep in mind that turning on
the water pump before the fan allows saturation of the pads, for
more efficient operation of the cooling unit.
Although generally less expensive than refrigerative
systems, portable swamp coolers have maintenance requirements
just like any other AC system. Proper maintenance of an evaporative
cooler includes keeping the unit clean, free from debris, and
making sure that the water is kept at the proper levels at all
time. Cooler pads should be replaced if they show signs of wear
and tear. The fan belt should be replaced if it is sagging. You
should carefully read and follow the user manual and instruction
that accompanies your unit to ensure proper maintenance and to
extend the life of your swamp cooler.
