WHAT IS EVAPORATIVE COOLING?
|
Evaporative cooling is a method of
converting hot air into a cool breeze using the process
of evaporating water. It is similar to the cool
refreshing effect you feel when you immediately step out
of a pool.
Evaporative coolers, or
swamp
coolers, utilize the
natural process of water evaporation along with an
air-moving system to create effective cooling. Fresh
outside air is pulled through wetted filters that cool
the air through water evaporation. A blower wheel then
circulates the cool air throughout a room, home, or
business.
We sell great products from
Champion, Essick and
Tradewinds along with all
replacement parts for
these coolers.

EVAPORATIVE COOLING = COOLER
TEMPERATURES!
|
Evaporative
air-cooling creates cooler temperatures a number of
ways:
|
- It lowers actual
temperature and will nearly always deliver
cooler air under a wide variety of typical
summertime climatic conditions.
|
- It lowers effective
temperature - the temperature you feel - by
at least an additional 4º to 6º. In some cases, the
temperature will be lowered more, depending on
relative humidity. The rapid motion of cool air
increases skin surface evaporation resulting in body
heat loss.
|
- It reduces radiated
heat. The constant flow of cool air absorbs
heat from all exposed surfaces and results in a
reduction of the heat radiated to the human body.

ENVIRONMENTAL BENIFITS OF USING EVAPORATIVE COOLERS
|
Evaporative
cooling provides 100% fresh, cool air continuously while
traditional refrigerated air conditioning utilizes a
closed system that recirculates the same stale dry air
over and over. Constant air movement of the evaporative
cooler pushes hot air out removing dust, pollen, smoke,
odor, and pollution and replaces it with cool fresh air.
Unlike air conditioning,
evaporative cooling does not require an airtight
structure to operate at maximum efficiency. In fact, you
need to allow your home to "breathe."
Opening doors and windows or
installing Up-dux™ vents to let air escape to the attic
properly ventilates your home.
Evaporative cooling is also an
environmentally-friendly alternative to air conditioning
since it has no CFC's or HCFC's.

ENERGY SAVINGS BY USING EVAPORATIVE
COOLERS
|
| Evaporative
coolers use 70% less power than air conditioning.
|
|
Example
A 1500 square foot home is located
in Phoenix, Arizona where the dry bulb temperature is
107, the wet bulb temperature is 71, and the wet bulb
depression is 36.
|
|
Air
Conditioner
Assuming air conditioning supplies
500 square feet of cooling per ton, 3 tons of air
conditioning would be required to cool a 1500 square
foot home. Since an air conditioner would probably run
most of the time in this climate, its electric usage
would be approximately 3.6 Kw per hour depending on your
utility.
|
|
Evaporative Cooler
Using an Essick, Champion or
Tradewinds cooler with a minimum of 5000 CFM and ¾
horsepower motor, total power consumption (motor and
pump combined) would be approximately 0.991 Kw per hour.
|
|
Results
If the air conditioner and the
evaporative cooler ran for a comparable period of time,
the ratio of energy for the evaporative cooler to the
air conditioner would be 0.991 Kw per hour to 3.6 Kw per
hour, or 0.275. This means the evaporative cooler would
use 72½% less power than an air conditioner to cool the
same area in the same environment.

|
Energy Cost Savings
Assuming a new energy cost of .14¢
per Kwh, this comparison would result in a possible net
savings of ($362.88 - $99.89) = $262.99 each month! With
this type of savings, evaporative coolers are a
significant cost effective alternative to air
conditioning.
