The ability to cool outdoor areas with misting fans depends on one major factor – the wind. With a prevailing wind, light wind or no wind you can achieve some remarkable results with water misting fans(see potential temperature drop chart and add 5 to 10 degrees for the wind chill factor). Normally speaking in outdoor areas it is advisable to use .012″ nozzles. (The exception being areas with extremely high humidity-60% and above where you would use .008″ or .006″ nozzles) Cooling outdoor areas with water misting fans is relatively straight forward and can be broken into 2 different types:
- Athletic Sideline and Amusement Outdoor Misting Fans
In this type of cooling, the people don’t mind getting damp, and more often than not prefer to. Generally, the misting fans are placed at head height, so people can stand directly in front of the misting fans and get wet or stand a few feet back and stay dry. - Restaurant & Back Yard Patio Water Misting Fans
When mist cooling large outdoor areas where the people do not want to notice the moisture. The misting fans should be set at their highest level with the misting fan, aimed slightly above the horizon with the oscillation set to match the area being cooled. If possible place the misting fans 10-20′ behind the area to be cooled. This will allow the cooled air to settle and keep the misting fans sound less noticeable.
