cooling
works on the principle of
heat
absorption
by
moisture
evaporation.
Simply
put,
heat
is
removed from the air as
water evaporates. You
feel this principle in
action when you step out
of a swimming pool or
shower and feel cool as
water evaporates from
the surface of your skin.
Your evaporative cooler
works
on
the
same
principle. The fan pulls
hot outside air through
the wet cooling pads,
where the air is cooled by
evaporation
and
then
discharged
from
the
