Abstract: A humidity control device (1) comprises: a processor (10) for dehumidifying air; a regenerator (30) for regenerating a hygroscopic liquid L used by the processor (10); a first hygroscopic-liquid pipe path (50) and a second hygroscopic-liquid pipe path (51) for circulating the hygroscopic liquid L between the processor (10) and the regenerator (30); and a heat pump (20) having an evaporator for cooling the hygroscopic liquid L to be used by the processor (10) and a condenser (22) for heating the hygroscopic liquid L flowing through the first hygroscopic-liquid pipe path (50). The regenerator (30) has: a first regeneration processing unit (31) and a second regeneration processing unit (34); a first tank (37) and a second tank (38) for containing the hygroscopic liquid L; and a heat source (44) for heating the hygroscopic liquid L to be supplied to the second regeneration processing unit (34).

Abstract: A humidity control device is for controlling the humidity of air in a target space, and the humidity control device comprises: a processor for controlling the humidity of air in the target space by passing air through a hygroscopic liquid L; a regenerator for regenerating the hygroscopic liquid L used for the process by the processor; a hygroscopic-liquid pipe path (50), provided so as to pass through a ventilation opening (70) intended for ventilating the target space, for transferring the hygroscopic liquid L from the processor to the regenerator; and a discharged-air-utilizing regeneration unit (60) for regenerating the hygroscopic liquid L by passing air to be discharged from the target space through the ventilation opening (70) through the hygroscopic liquid L flowing through the hygroscopic-liquid pipe path (50) toward the regenerator. A humidity control device whose energy utilization efficiency is improved is thus provided.
