Claim Text:
1. A dehumidifying system, comprising: a main body that includes an inlet port that sucks air from a dehumidification target space and an outlet port that supplies air to the dehumidification target space; an air passage provided in the main body, the air passage connecting the inlet port and the outlet port; a first moisture adsorption/desorption device including a first adsorbent in which a first equilibrium-adsorption capacity with respect to air with a relative humidity ranging from 40 to 100% increases in a substantially linear manner with respect to an increase in the relative humidity, the first adsorbent desorbs moisture to air with a low relative humidity, and absorbs moisture from air with a high relative humidity; a second moisture adsorption/desorption device disposed in the air passage and disposed so as to be spaced apart from the first moisture adsorption/desorption device, the second moisture adsorption/desorption device including a second adsorbent in which a second equilibrium-adsorption capacity with respect to air with a relative humidity ranging from 40 to 100% increases in a substantially linear manner with respect to an increase in the relative humidity, the second adsorbent desorbs moisture to air with a low relative humidity, and absorbs moisture from air with a high relative humidity; a cooling device disposed between the first moisture adsorption/desorption device and the second moisture adsorption/desorption device, the cooling device cooling air that has been humidified by desorption release of moisture from the first moisture adsorption/desorption device or the second moisture adsorption/desorption device; and switching devices disposed in the air passage, the switching devices switching between a first path in which the air sucked from the inlet port passes through the first moisture adsorption/desorption device, the cooling device, and the second moisture adsorption/desorption device in this order, and a second path in which the air sucked from the inlet port passes through the second moisture adsorption/desorption device, the cooling device, and the first moisture adsorption/desorption device in this order, wherein the first moisture adsorption/desorption device, the cooling device, and the second moisture adsorption/desorption device are disposed in series in an air flowing direction in the air passage so that sides through which air passes face each other, and during desorption, the air sucked from the inlet port directly flows into the first moisture adsorption/desorption device and the second moisture adsorption/desorption device without being heated to reduce relative humidity.
