<p>PROBLEM TO BE SOLVED: To reduce energy consumption in a system using a dry rotor to feed air of low dew point. SOLUTION: The ratioαof passing gas volume of a regeneration area 12b to a dehumidifying area 12a set in a freely rotatable rotor 12 is set to 0.2<=α<0.4 and also the ratioβof passing gas volume of a purge area 12c thereto is set to 0.09 <=β<0.2. Air that has been subjected to dehumidifying treatment by the dehumidifying area 12a is fed to a low dew point space R, and a part of mixed air of returned air RA and outdoor air OA is introduced into the dehumidifying area 12a, and a part of the remainder is introduced into the purge area 12c, and air that has passed through the purge area 12c is introduced into the regeneration area 12b.</p> |
