- the suction rotor (24) is provided so as to cross the first passage (21) and the second passage (22). In the suction rotor (24), the adsorbent comes into contact with the first air in a portion crossing the first passage (21), and the adsorbent comes in contact with the second air in a portion crossing the second passage (22).
- the suction rotor (24) is driven and rotated by a motor (not shown).
- the rotation speed of the suction rotor (24) is adjustable. Adjusting the rotation speed of the suction rotor (24) changes the ability to exchange heat and moisture between the first air and the second air.
