Fuzhou JINGHUI evaporative cooler produces effective cooling by combining a natural process -- water evaporation -- with a simple, reliable air-moving system. Fresh outside air is filtered through the saturated evaporative media, cooled by evaporation, and circulated by a blower wheel.
Water from the bottom pan of the unit is pumped to the top and allowed to flow down over the evaporation cooling pads of the spot cooler, evenly saturating the pads. Then, a powerful blower pulls air through the pads, forcing the water to evaporate which lowers the ambient temperature. The cooler air is then blown by the unit at a high velocity where you direct the cool air to go.
