Outdoor Cooling in hot climates like Dubai and Abu Dhabi is a very hard mission to be achieved and its almost impossible to be done with traditional air conditioners and AC, since current AC designed to circulate and re-cool the same air, in outdoor AC case there is no way to circulate the same air. So need 100% fresh air supply all the time, and the Air conditioner must handle high Delta temperature.
The other thing is necessary in outdoor cooling is the amount if air, since outdoor cooling needs 5 to 10 times more air with high velocity.
The first option for outdoor cooling is using outdoor AC and spot air conditioners.
This particular type of industrial air conditioners designed to work outdoor and can handle high temperature with no air circulation.
The other option is using outdoor coolers (Evaporative coolers)
Air Coolers using water evaporation for cooling, similar. This evaporation process lowers the temperature. Evaporation of water consumes latent heat that taken from the air causing lower temperature of the air.
When dry air enters into an Air Cooler, throw this air throws the wet evaporative pad Cooling Media where it evaporates faster with the large surface. Then the cold air sucked by a powerful fan.
An evaporative air cooler works best in outdoor spaces and open areas. The massive high-pressure amount of air produced by the cooler will increase the people comfort level. And can help people to enjoy outdoor events and parties.
