1. A water-cooled fan is an electrical appliance that combines the advantages of a regular fan and air conditioning, and can also bring a refreshing feeling to indoor residents. It is mainly used for indoor cooling in hot summer. The water-cooled fan is mainly composed of water absorbing fan blades or fan blade surfaces, as well as water supply devices. Its obvious advantage is that it has a large water evaporation capacity and brings a large air volume, and the cooling effect in summer is very obvious.

2. The water-cooled fan uses a circulating water pump to continuously extract water from the water tank and spray it evenly on the evaporative filter layer through a water distribution system. Outdoor hot air enters the evaporative cooling medium and exchanges heat with water in the evaporative cooling medium. The cool and clean air that is cooled by adding water for evaporation and heat absorption is pressurized by a low noise fan and sent indoors, allowing the indoor hot air to be discharged outdoors, thereby achieving the goal of indoor cooling.

3. Water cooled fans are very economical. Ordinary air conditioners cost thousands of yuan per unit, while water-cooled fans cost only a few hundred yuan per unit. In addition, ordinary air conditioners consume a lot of electricity, requiring 1 or even a few kilowatt hours of power in an hour, while water-cooled air fans are very energy-efficient and energy-efficient.
