How Mist Cool Systems Work

HOW A MIST COOLING SYSTEM WORKS?

Misting systems work by forcing water via a high pressure pump through a mist nozzle that has an orifice of about 5 micrometers (thickness of a human hair), thereby producing a micro-fine water vapor. The water droplets that create the mist are so small that they instantly flash evaporates. The water droplet when introduce to the hot air  turn into gasses which can reduce temperatures by as much as 25 degrees in just seconds.

A properly designed and installed mist cooling system can be used in both dry (arid) and humid climates, it is vital that you determine the climate conditions when using a mist system. Understanding the dynamics of evaporative cooling principals (water flow) in the design and application of a mist cooling system will enhance the effectiveness of your cooling application. In climates that are dry and hot, large amounts of water can be introduced into the environment for cooling purposes.  In climates that have high relative humidity less water is required for cooling.

The use of mist fans in a high humidity environment is strongly recommended as the fan (convection cooling) will create a wind-chill in which to move conditioned air about the area you are trying to cool. When measuring the cooling effects of a flash evaporative cooling system, the temperature drops are based on ambient temperature, and since a mist system does not refrigerate the air  and since the system is used in open-air or outdoor environments it is not possible to accurately measure the air temperature. A mist cooling system is used for applications such as patios, pets, livestock, warehouse and produce cooling in greenhouses.
 

  • In-expensive to install
  • Low estimated cost of operation
  • Low power and water consumption   (GREEN)
  • Ease of maintenance
  • The constant movement of air through the venue reduces pollutants and odors
