Air coolers in China

Versatile, lightweight, and economical, this evaporative air cooler easily rolls from room to room for use anywhere in the home or office.

Unlike a fan that blows hot air and more energy efficient than an air conditioner, the appliance uses water to cool a personal space up to 12 degrees lower than the ambient temperature.

The air cooler works by endothermic reaction (a reaction that consumes heat). The unit sucks air through a wick saturated with water; as the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air.

A cool air stream then gets blown out the front of the unit through oscillating louvers for even distribution.
