How Mist Keeps You Cool
So how do misting systems work? The secret to your outdoor comfort lies in the science behind evaporative cooling. A misting system usually consists of a series of nozzles placed around the perimeter of your patio or outdoor entertaining space, connected through a series of stainless steel pipes.
A high-pressure pump is connected to the water source, which increases the water pressure by up to 10x its normal rate. By increasing the water pressure above 700 psi, the water molecules are atomized, pushing the smallest possible droplets through the nozzles.
As the water droplets are introduced to the hot outside air, they flash evaporate. The process of evaporation requires a source of energy: in this case, the hot air. The water particles absorb the heat, causing the molecule to evaporate. This process is repeated for each droplet and, as the misting system continues to spray, the surrounding air can be cooled by more than 30 degrees Fahrenheit.
