Common Questions About Mist Cooling
April 2, 2008
The most common question asked about mist cooling is: How much water and electricity is used? Being that the pumps are designed to run off of a standard outlet, just like plugging in a lamp, your pump will use about 4- 10 cents an hour. As for the water use, the average 12 nozzle system will use around 10 gallons of water an hour. Compared to the average shower that takes 10 minutes an consumes 35-40 gallons of water, it’s easy to see how efficiant a mist cooling system is.
The second most common question is: Won’t a misting system get everything wet? Being that we are in Florida and the humidity is high, this could be a concern. With a well designed and installed system, and a little education, this won’t be an issue for long. What you need to know is anything placed within 6 feet of a nozzle will collect moisture. The idea here is to let the mist evaporate. Water is feed through a high pressure pump, forced through a tiny oriface in the misting nozzle creating microscopic droplets of water or the mist. The mist then absorbs the energy in the air, which is the heat, causing the mist to evaporate and cool the air at the same time. An ideal situation is to have your mist lines and/or mist fans placed 8-10 feet up, use the natural winds, and let the mist fall. Remember, heat rises, so by the time the mist reaches you, all you feel is the desired cooler air.
