HOW EVAPORATIVE COOLING WORKS
Evaporative cooling is nature’s way of cooling. When air is
moved over a wet surface, water is evaporated and heat is
absorbed. When stepping out of a swimming pool with the wind
blowing, evaporative cooling makes you feel cool, even though
the air may be warm. The human body itself is cooled primarily
by the evaporation of perspiration.
This unit works on the same principle. Air is drawn across
wet fi lter pads where the air is cooled by evaporation and then
circulated throughout the building. It is this combination of
cooled air and the movement of air over the skin which makes it
feel cool.
Unlike refrigeration systems which recirculate the air, an
evaporative cooler continually brings in fresh air while
exhausting old air. You are completely replacing the air every 2
to 4 minutes by opening windows or doors or a combination of
both. The air is always fresh, not stale, laden with smoke and
odors as happens with refrigerated air conditioning.
