The evaporative cooling system is a process that reduces air flow temperature by water evaporation.
Maximum efficiency is achieved by directing the air to be cooled through wet pads placed at the inlets of the air ventilation system.
As the air passes through the pads it absorbs water, which provides a higher capacity for heat removal.
The larger the amount of water evaporated from air, the higher the temperature reduction shall be. Also, the dryer the air or the lower the relative humidity, the greater the possibility of evaporation will be.
This way, by air humidification together with an appropriate ventilation design achieving adequate circulation and renovation rates, it’s possible to reduce the temperature inside the house between 5 and 14ºC.
