Warm air is drawn through wetted filter pads. The outside air temperature is lowered by the evaporative process and the cool air is directed into your home.
When sensing a breeze we feel cooler, even though the air stream produced by the breeze is the same temperature as the air. The cooling effect of air in motion is due to increased skin surface evaporation. Heat is removed from the body so you feel cooler. The effective temperature drop can be from 2 - 4 degrees below the still air temperature.
In your home, under normal temperature conditions, heat is radiated from the human body to surrounding walls and ceilings. However, as the temperature approaches 34-35 deg the heat is radiated back to the human body. Evaporative air conditioning prevents this by absorbing heat from the walls and ceilings with a constant flow fo cool air-which ensures that people occupying your home can radiate heat a a faster rate and therefore remain much cooler.
With evaporative air conditioning there is a continuous flow of air into your home. Fresh and cool, this air forces out stale air. Outside air often contains dust, pollen and pollutants, these are prevented from entering your home by filtering outside air through wet filter pads, flushing out all airborne material from the air. Great for allergy sufferers. |
