Answer:
The water when evaporated from a desert cooler absorbs energy from the surrounding for compensating the loss of energy during evaporation making the surrounding cool. Evaporation is inversely proportional to humidity. So on a hot dry day, the evaporation is more so the surrounding is more cooled.
