Evaporative Cooling Advantages
Evaporative coolers cost less to purchase, less to install and less to operate. Evaporative cooling technology does not use a compressor. The only parts that require electricity are a pump and motor. Studies of evaporative cooling versus typical air conditioning reflect between a 70% and 80% cost savings. Maintenance costs are relatively low as a homeowner with basic repair knowledge can make changes to the pads, motor and pump as well as periodic cleaning. Most residential evaporative systems use a 120-volt electrical supply which means they do not require a costly high voltage circuit.
Improved air quality is a major benefit to the occupants of the home as a constant volume of fresh air is introduced into the home. This repetitive exchange of air assists in removing odors and contaminates in the home. As outside air passes through the wet filter pads particles of pollution (smog, smoke, allergens, dust) are trapped in the filter fibers and do not enter the home. Most homes create their own indoor pollution through adhesives, carpeting, upholstery, manufactured wood products, pesticides, paints, tobacco smoke and cleaning agents. Many of these items create volatile organic compounds (VOC) and can be harmful to the health of people and pets. Evaporative cooling uses an open system to cool, meaning that windows must be open to effectively move air to cool the space. This allows for indoors contaminates to be expelled from the home. A typical air-conditioning system uses a closed system, meaning that windows and doors must be closed to cool the space.
This means that contaminates remain trapped in the home for extended periods. In especially dry climates the added humidity in the air prevents dry skin and promotes the health of animals and indoor plants. The technology of evaporative cooling is very simple and environmentally friendly. Since the system does not use a compressor no harmful chemical agents are introduced in the environment like Chlorofluorocarbons. Chlorofluorocarbon is an organic compound used in refrigeration units and air conditioners. They are also used as aerosol propellants. In the mid -1970's it was discovered that these chemical types contribute to the depletion of the upper atmosphere. Evaporative coolers use only small amounts of electricity and water. Evaporative cooling is not only a cost effective choice but a healthy environmentally friendly choice.
