Industrial water-cooled fans, as the name suggests, are fans that use the principle of water evaporation to achieve cooling. It adopts efficient "direct evaporation" refrigeration technology, which absorbs heat energy during the evaporation process of water, thereby reducing the temperature of the air. Specifically, fresh air passes through the core component of an evaporative air conditioner - the interlocking and overlapping heat exchange moisture curtain filter, which removes wet dust from the air and lowers the temperature of the circulating water, which is equal to the wet bulb temperature of the air, to a temperature close to the wet bulb temperature.

The working principle of water evaporative cooling fan is based on the phenomenon of heat absorption through evaporation. When water evaporates, it changes from a liquid state to a gas state, which requires absorbing a large amount of heat to lower the temperature of the surrounding environment. The evaporative cooling fan extracts water through a circulating water pump and evenly sprays it onto the evaporative filter layer. When outdoor hot air enters the evaporative cooling medium, it undergoes sufficient heat exchange with water molecules, absorbs heat through water evaporation, and cools down. Finally, it is pressurized by a low-noise fan and sent indoors to achieve indoor cooling.
