Evaporative air conditioning uses evaporation to cool the air. In an evaporative cooler, a pump circulates water from the reservoir on to a cooling pad, which in turn becomes very wet. A fan draws air from outside the unit through the moistened pad. As it passes through the pad the air is cooled by evaporation. The key to effective evaporative cooling is ensuring that each of the cooling pads is completely saturated at all times during operation and that the systems fan & motor are sized and designed to deliver the appropriate airflow for the required environment.
• Estimated cost for professional installation is about half or less that of central refrigerated air conditioning.
• Estimated cost of operation is 1/8 that of refrigerated air conditioning.
• No power spike when turned on due to lack of a compressor.
• Power consumption is limited to the fan and water pump, which have a relatively low current draw at start-up.
• The working fluid is water. No special refrigerants, such as ammonia or CFCs, are used that could be toxic, expensive to replace, contribute to ozone depletion and/or be subject to stringent licensing and environmental regulations.
