How Misters Cool You Down
When water molecules evaporate into the air, the water changes from a liquid to a gas state. A certain amount of energy or heat is needed to assist this process of changing water from a liquid to a gas, which is automatically drawn from the surrounding air – thus, evaporationlowering the ambient temperature around the misted area.
This is essentially the same way your body cools itself off. You sweat, the sweat evaporates, and your body temperature lowers. When installed and used properly, mist cooling systems can reduce temperatures by as much as 30°F depending on the efficiency of the misting system, relative humidity, and outdoor temperature.
