Report: Analysis of Potential for Minimum Energy Performance Standards for Evaporative Air Conditioners

Category: Space Heating and Cooling

Date: 03/03/2001

The scope of this report includes all domestic and commercial evaporative air conditioners, also known as evaporative air conditioners, evaporative air coolers and 'swampies'. They generally draw in warm outside air and pass it through a series of wetted filter pads that cool it through evaporation before discharging the air into the space to be cooled. Evaporation of water in the filter pads lowers the temperature of the air and increases its humidity.Evaporative coolers are more effective in climates where the temperature is high and the humidity is low. In Australia, this generally means the southern coastal areas plus most of the inland areas. In terms of capital cities, Perth, Adelaide, Melbourne, Canberra and Hobart would be suitable for evaporative coolers. Sydney's climate is marginal and Brisbane and Darwin are too humid for most of the cooling season.An extensive range of evaporative coolers is available, from small portable units for domestic use to large ducted systems for commercial and industrial use.
