Desert Cooler Trainer works on the principle of evaporative cooling. It is used mostly in the

dry hot regions; it consists of a fan which sucks the air from atmosphere through the pads

which are used in desert coolers very frequently. The difference in DBT & WBT at inlet and

outlet  can  be  measured  hence  the  RH  from  the  charts. Also  the  amount  of  water

evaporated can be calculated by knowing the water level difference in the reservoir.
