Benefits of humidification using evaporative cooling.

For more on benefits and effects of humidification using evaporative cooling see https://vpdcalc.blogspot.com
For information on evaporative cooling see https://en.wikipedia.org/wiki/Evaporative_cooler
Example: The air temperature is 25 deg C and the wet bulb temperature is 15 deg C. If the efficiency of evaporative cooling is 20% then the air will be cooled (20/100)(25-15) = 2 deg C See https://en.wikipedia.org/wiki/Evaporative_cooler#Performance
