How air-cooling takes place
◊ Air-cooling through misting uses the laws of physics in a process known as adiabatic process. This method converts liquid into gas ( vapor) which results in temperature reduction.
◊ In this case, the energy necessary for the water to evaporate comes from the temperature of the surrounding environment, which means that the cooling becomes more intense as the evaporation increases. In order to achieve this, the water must be diffused into small particles /micro drops/ which need to be quickly vaporized.
◊ The pumps and special nozzles with which our cooling systems are equipped convert the water into mist of micro drops 3 microns in size. These micro drops absorb the heat from the air and are vaporized. In the course of this process the temperature decreases up to 10�C and a cooling breeze is generated. Therefore, the hotter and drier the air the more intense the evaporation, and consequently the cooling, process is, which regulates temperature naturally at the place of evaporation.
◊ The mist cooling systems are much more effective than other conventional open-air cooling systems. In addition, they ensure lower costs and greater energy saving as well as easy assembly and maintenance.
◊ An important factor here is also the psychological and visual effects created by the falling mist.
◊ Another beneficial effect of the mist cooling system is the filtration of the surrounding air. The free fall of the micro drops attract and pull the surrounding air particles to the ground. This also applies to flying insects whose wings become laden with the water drops, thus creating a natural filtration wall, which blocks hot air, dust, and insects.
Everyday examples showing the principles of misting and cooling
◊ The Wet T-shirt phenomenon
When you put on a wet T-shirt you become cold instantly. This is due to the fact that the water starts to evaporate which cools you down and reduces your body temperature.
Sweating is a natural process, which cools the human body and regulates temperature on hot days. The hotter your body becomes the more intense the sweating process is.
Have you noticed that the air is always cooler around fountains and/or equipment creating water effects? This is due to the intense diffusion and evaporation of water.
◊ Cooling your drink through high temperature
Just take a wet towel and wrap it around your drinking glass or bottle, then leave it in the sun. In a moment your drink will be a few degrees cooler.
