This outdoor cooler works best in places where the environment is hot and dry. Factories and workshops that have large area of which spot cooling is required in certain location can make use of this device. It is not able to work well in humid condition as the air has already been saturated with water moisture. In order for air to be cooled, it has evaporate some of the water.
The outdoor cooler has a fan that sucks in the hot and dry air from the room. This air is then passed through a layer of specially made damp pads. The pads are kept damped by the use of a water pump that continuously circulate water inside this equipment.
This conditioned cooled air is then discharged to the room by the same fan. As the air passes through the pads, it is filtered and contaminants such as dust, dirt and other pollutants are stuck on the surface of the pads. You will then get a cleaner and cooler air.
