Evaporative Cooling vs. Air Conditioning

Evaporative Cooling Air Conditioning
Description
1
  • Uses a fan and pads saturated with water
  • Open system requires exhaust locations such as doors and windows
  • Air is pulled in, cooled, then through duct or rooms, then exhausted through locations such as open doors and windows
Description
2
  • Compressor and refrigerant used
  • System must be closed
  • Cooled air is pushed through ducting in the home and recirculates
 Advantages

  • 75% less cost to operate than refrigerated AC and the installation cost is 25%-50% less
  • No harmful chemicals, so no potential for links
  • Cool, clean air created without chemical refrigeration
  • Air is purified and cooled as it passes through water soaked pads
  • Adds humidity to dry air
  • Fresh air from the outdoors is always circulating
 Advantages

  • Air produced is generally cooler than that of Evaporative coolers
  • Air is cleaned as it passes through a filter
  • Decreases humidity
  • Airborne particles and allergens are reduced
 Disadvantages

  • Not as much cooling as refrigerated AC systems
  • Most effective in areas with high heat and low humidity
  • Air must be exhausted so windows and doors must be open
 Disadvantages

  • Significantly higher operating costs
  • First time installation costs are much higher than Evaporative Cooling
  • Licensed contractors must perform maintenance
  • Air is recycled rather than bringing in fresh outdoor air
  • Uses refrigerant, which is dangerous and harmful to the environment
