A dehumidification type air system is configured such that a switching valve and an air-used device are connected through a dehumidifying member made of a polymer permeation membrane with moisture permeability, and by bringing a moisture emitting face of the dehumidifying member into contact with the atmosphere, supply air supplied from the switching valve through the dehumidifying member to the air-used device is dehumidified by the dehumidifying member, while the moisture permeating through the dehumidifying member is diffused from the moisture emitting face to the atmosphere through natural evaporation. |
