The principle to lower the temperature The cooling process of this systemis is finished in its core – wet curtain Paper. There is a thin layer of water film in the corrugated fiber paper surface. When the dry outdoor air passes through wet curtain paper by the suction fan, the water of water film absorbs heat in the air and been evaporated then , carrying away lots of latent heat. This process makes the air temperature lower. The cooler air enters the room, then is exhausted to the outside through the fan after the mixture of indoor thermal turbidity air.
