<p>PROBLEM TO BE SOLVED: To provide a dehumidifier that can supply air with a low dew point even when a regeneration temperature is low and that can easily correspond to conditions on an installation site.SOLUTION: A first dehumidification rotor 1 and a second dehumidification rotor 4 are installed. This dehumidification device includes: a blower 8 for making outside air that is cooled and dehumidified by a first cooler 7 pass through an adsorption zone 2 of the first dehumidification rotor 1, making air that has passed through the first dehumidification rotor adsorption zone 2 pass through an adsorption zone 5 of the second dehumidification rotor 4 to supply the air to a dry room 11 as supply air SA, mixing return air from the dry room 11 with air that has passed through the first dehumidification rotor adsorption zone 2, heating air that has passed through a second dehumidification rotor regeneration zone 6 by a regeneration heater 14 to make the air pass through a first dehumidification rotor regeneration zone 3, and sending outside air to the first dehumidification rotor adsorption zone 2; a blower 15 for discharging the air that has passed through the first dehumidification rotor regeneration zone 3 to outside; and a blower 9 for sending the air that has passed through the first dehumidification rotor adsorption zone 2 to the second dehumidification rotor adsorption zone 5. Return air from the dry room 11 is supplied to the suction side of the blower.</p> |
