    • So as long as the ambient air isn't already saturated, 100% relative humidity, you can actually cool water below the dry bulb temperature using evaporation.

      So as long as the ambient air isn't already saturated, 100% relative humidity, you can actually cool water below the dry bulb temperature using evaporation.

    • And the lower the humidity of the air, the more evaporation can take place, so the bigger the difference in wet and dry bulb temperatures.
