An evaporative cooling system is eco friendly. Evaporative cooling uses the same cooling principles as found in nature. Evaporative cooling is close to the same effect you feel of cool air when you stand near a waterfall.
The evaporative cooling system uses up to 90% lower peak energy, which implies lower wiring costs. It can be easily used with solar energy and lower requirements of additional power systems.
Evaporative coolers cool the air without the use of refrigerants which can harm the ozone layer. It implies 80% less production of green house gases.
It is the best solution for cooling the drier areas, such as Colorado, with higher humidity. Using an air conditioning system will tend to dehydrate the air.
The wet filters used in evaporative cooling method helps filter the air.
People with severe allergies enjoy evaporative cooling system as they feel wet air less irritating.
Evaporative cooling lowers actual temperature and will nearly always deliver cooler air under a wide variety of typical summertime climatic conditions.
Evaporative cooling 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.
Evaporative cooling 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.
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."
Are evaporative coolers expensive to operate?
Evaporative coolers use 70% less power than air conditioning.
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 72 ½% 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.
