You will only get wet if you are standing within 6′ of the
Yes. The evaporative cooling concept will work any time you are able to achieve evaporation. The more complete the evaporation, the more effective the system will work. For areas with humidity above 80%, temperature reductions will be as high as 10 degrees. For humidity levels between 40% and 80%, temperature reductions will be as high as 20 degrees. Below 40% humidity, the temperature reductions may be as much as 35 degrees.
1. Low-Pressure Misting Systems
These systems operate between 40 and 100 psi of water pressure. The variance in pressure is because they operate on your household water pressure and not a pump. Normally built with PVC or poly plastic tubing and are connected to a water hose. Typically found on outdoor patios and the misting will get you wet but cool if you are standing nearby.
2. Mid-Pressure Misting Systems
The systems operate between 100 and 250 psi of water pressure. A Mid-Pressure Pump is utilized to increase the pressure of the water flow. It is perfectly suited for backyard and patio misting.
3. High Pressure Misting Systems
The systems operate between 800 and 1200 psi (pounds per square inch) of water pressure. The systems will work very effectively in both low and high levels of humidity. Even when the humidity exceeds 90%, the effects of the system will be felt with the rapid drop in temperature and make you feel cool and more comfortable. High-Pressure Systems create the most BTU’s because the systems produce smaller MIST and creating more cooling evaporation.
As the micron water droplets flash evaporate they pick up heat from the air, which significantly drops the temperature between 25 and 35 degrees Fahrenheit, without making you wet.
Most nozzles clog because hard water deposits accumulate in the nozzle (like the white residue left on a shower door). The best way to clean nozzles is to use a retail product like CLR -Calcium / Lime and Rust Remover which can be purchased at any grocery store.
Step 1: Scrap a knife across the small hole in the nozzle (don’t poke into the hole)
Step 2: Mix 1/2 warm water 1/2 CLR in a small jar – place the clogged nozzle in the jar and shake vigorously for 20 seconds, let sit for a few seconds and shake another 20 seconds.
Step 3: Remove nozzles from the jar and hold the nozzle by the threads and tap it on a hard surface (like a countertop)
Step 4: Rinse with fresh water and most nozzles will be unclogged
** If you have a jewelry cleaner (ultrasonic bath) use that instead of the jar.
Water temperature does not have a great effect on the cooling produced through evaporation. At 90º F (32º C) it takes 9,000 BTUs (2.268 kilocalories) to evaporate a gallon of 50° F (10º C) water and 8,700 BTU (2.192 kilocalories) to evaporate a gallon of 90º F. water. In this example, the water is 180% warmer and results in only a 3% reduction in the amount of heat absorbed.
