How do misting systems work?
Misting systems are most commonly defined as a series of specially mist nozzles placed in a line around the perimeter of an area. When connected to a high pressure misting system pump, water is forced through the specialty nozzles and quickly atomized to droplets as small as 5 millionths of a meter (5 microns).
Misting systems will produce billions of tiny droplets every second. If these droplets are introduced into an outdoor area, they quickly evaporate. This process of evaporation requires energy to be completed. The energy is taken from the air in the form of heat. The result is a temperature reduction of up to 35 degrees Fahrenheit, depending on the ambient temperature and the relative humidity of the air. This method of temperature reduction is the most common use for all misting systems.
When misting systems are placed inside an enclosed area (such as a greenhouse), the billions of droplets that are produced will initially provide cooling as the droplets evaporate. However, if the air exchange is limited, the misting system will continue to increase the humidity level within the structure. Humidity levels as high as 90+% are possible. This unique characteristic of all misting systems makes them ideal for both outdoor cooling and humidification.
