Evaporative Air Cooler Positive Pressure System

Evaporative Air Cooler is a positive pressure ventilation system device that have the ability to cools air through the evaporation of water. Different from typical air conditioning systems, water evaporative cooling uses water to absorb a relatively large amount of heat from dry buld in order to evaporate.The temperature in dry buld (Dry air in the ambiance) can be dropped significantly through the phase transition from liquid water to water vapor (gas / steam). This can cool air with much less energy compare to typical refrigeration system, but with certain temperature limitation (lowest at water temperature at particular ambiance condition).
This evaporative temperature drop chart is based on 85% saturation efficiency

This mode of installation mostly apply at general area cooling which the ground operation does not affected by its high velocity air supply (air travel speed).

It also required minimal fabrication cost (ducting).

The ventilation calculate based on air changes per hour to the general area contain. 

Air velocity and temperature from point A to B may vary due to air barrier loss.

This mode of installation can distribute effectively required air volume to particular cooling spot. 

With proper insulation, the temperature from point A to B may maintain in good manner.

This mode require certain amount of duct fabrication, but better cool air distribution to the needed spot.
