PROBLEM TO BE SOLVED: To provide a dehumidification system improved in moisture absorption capacity by combining an indirect evaporative cooling device of a simple construction with a desiccant humidity control device.SOLUTION: A dehumidification system includes: an indirect evaporative cooling device 1 including a dry flow passage 11, a wet flow passage 12, which can exchange heat with each other, and a liquid supply means 13, and cooling a gas flowing in the dry flow passage 11 without humidifying the same by drawing heat from the surroundings as evaporation heat when liquid supplied to the wet flow passage 12 is evaporated by a gas flowing in the wet flow passage 12; and a desiccant humidity control device 2 including a moisture absorption flow passage 21, a moisture desorption flow passage 22 and a desiccant rotor 20, and performing moisture absorption to a gas flowing in the moisture absorption flow passage 21 and moisture desorption in the moisture desorption flow passage 22. An inlet of the dry flow passage 11 and an outlet of the wet flow passage 12 are brought in communication with the outdoors, a connection flow passage is connected between an outlet of the dry flow passage 11 and an inlet of the moisture absorption flow passage 21, a connection flow passage is connected between an outlet of the moisture desorption flow passage 22 and an inlet of the wet flow passage 12, and an inlet of the moisture desorption flow passage 22 and an outlet of the moisture absorption flow passage 21 are brought in communication with the interior. |
