The cooling principle of JHCOOL evaporative air cooler
Getting out of a pool and standing in a breeze will help you feel cool, even on a hot summer day. This is the principle behind evaporative cooling. Evaporative coolers are cooling systems that only use only water and blower to circulate air. In this system, warm, dry air is pulled through a water-soaked pad. As the water evaporates, a cooling effect on the surrounding air occurs.
