The special nozzles with winch the cooling system are equipped, convert  the water into micro drops, 3 microns in size. Those micro drops absorb the heat from the air and are vaporized. In course of this process, the temperature decreases up to 10 degrees, and the cooling breeze is generated. Therefore, the hotter and drier the air is, the more intense the evaporation, and consequently the cooling process is, which regulates temperature naturally at the place of evaporation.
