Cooling Efficiency Relative Humidity is the amount of moisture in the air compared to the amount of moisture the air could absorb at the same temperature. This is a crucial factor in determining the cooling potential of the environment in the presence of humidity. The lower the relative humidity the greater the amount of water that can be vaporized, resulting in a greater amount of heat that is removed from the air.
So…can mist cooling work in humid environments? YES, it does work, but not as effectively as in a drier environment. To get the most effectiveness in both environments high pressure (600-1200 psi) pumps must be used.
