Abstract: There is provided a dehumidifying device for dew point temperature adjustment that adjusts a dew point temperature of air to a temperature of about ?20° C. or lower, the device including an adjusting unit that adjusts a dew point temperature by adjusting at least one driving operation that is selected from a rotational frequency of a supply fan for supplying air into the dehumidifying device for dew point temperature adjustment, a rotating speed of a dehumidifying rotor, an opening degree of a blow-out air volume adjustment damper, a rotational frequency of an exhaust fan for exhausting air, and an opening degree of an exhaust air volume adjustment damper.

Abstract: Provided is a coating device including a coating portion where coating treatment is performed, a partition portion covering the coating portion, and a humidity controller adjusting an amount of moisture in a work space partitioned by the partition portion.

Abstract: A dry room that controls a dew point temperature in a space to be managed, the room includes a plurality of exhaust units that exhaust air in the space to be managed, in which the plurality of exhaust units are disposed in different regions in the space to be managed, and individually adjust an exhaust amount of the air to be exhausted from each of the regions.

Abstract: A low-humidity air supply device which supplies low-humidity air into a dry room includes an intake portion that is connected to an inside of the dry room and through which air in the dry room is taken in, a cooling unit that cools the air taken in through the intake portion, a dehumidification unit that dehumidifies the air cooled by the cooling unit, and a supply unit that is connected to the inside of the dry room and through which the air dehumidified by the dehumidification unit is supplied into the dry room, in which at least one of the intake portion, the cooling unit, the dehumidification unit, and the supply unit is composed of a duct having a box shape through which the air is able to pass, and the duct is a portion of a casing that constitutes an outermost layer of the low-humidity air supply device.

Abstract: A booth including an ejecting unit that ejects air into an opening portion leading to an internal space partitioned from an external space. The ejecting unit forms a first airflow that suppresses introduction of a disturbance from the external space into the internal space and a second airflow that suppresses introduction of the first airflow into the internal space inside the first airflow.
