Abstract

A dehumidification system configured from a first dehumidification unit (60) having an outside-air-cooled heat exchanger (61), a second dehumidification unit (20) that uses two adsorption heat exchangers (22, 24) by switching air channels, and a third dehumidification unit (30) having an adsorption rotor (31), wherein it is possible to reduce regeneration energy for the third dehumidification unit (30), and to conserve energy and reduce costs in the dehumidification system, by supplying the third dehumidification unit (30) with low-temperature and low-humidity air that was cooled and dehumidified by the second dehumidification unit (20).
