“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 an environment in the presence of higher humidity. The lower the relative humidity the greater the amount of water that can be “flash evaporated,” 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.
