Evaporative
Cooler Performance
Homeowners
can use the cooler index to decide when to switch between evaporative
cooling and air conditioning. As a general rule, if a cooler produces
air colder than 70°F, it will create a comfortable environment;
if
it produces air hotter than 75°F, it will not. Between
70°F and
75°F is a gray range in which some people are comfortable and
some
are not.
Evaporative
cooler
index for standard aspen-pad coolers.
Enter the table from
the left
with outside
air temperature and the top with outdoor humidity. Where the row and
column meet is the temperature of air a typical evaporative cooler will
produce. The cooler index can also be used to check the performance of
cooler pads.
An alternate way to
determine
pad
performance is to check the temperature of the air leaving the cooler
against the cooler index. The cooler index is the anticipated
temperature of the air leaving an aspen pad cooler and accounts for
heat added to the air by the pump and fan motors and a cabinet exposed
to the sun. The cooler index has the advantage of enabling the
homeowner to check cooler performance by watching the news and checking
the temperature of the air leaving the diffuser in the house.
If this
temperature is 3°F or more higher than the cooler index
indicates
as normal, the cooler is not operating as well as it should be,
probably due to a malfunctioning water distribution system, sagging
pads, or poorly manufactured aspen pads.
