Designed with the system of micro-computer control, this fresh air for evaporation can lower the temperature and humidify the air through the principle of evaporation. Provides flexible and economical way to cool and humidify the surrounding environment immediately. Features 3-D Cooling Pad and rotating shutters for added cooling and air distribution. The Cooler easily rolls from room to room and can also be used as a fan or humidifier if temperature is not a problem. The remote allows you to change your settings. Fresh air works by endothermic reaction (a reaction that consumes heat), which draws air through it in 3-D Cooling Pad (waterlogged). Air flows through the pad, a part of the water evaporates into the air, consuming the heat that was in the air. A flow of air is blown out the front of the unit and is considerably cooler than the room temperature is running! This is not an air conditioner and therefore uses much less energy.
