<p>PROBLEM TO BE SOLVED: To obtain a small sized rotor for dehumidifier at a low cost by a method wherein a dehumidification air passage through which air to be dehumidified is ventilated is provided before and behind a rotor impregnated with a moisture absorbent, a regeneration air passage through which air for regeneration of the moisture absorbent is ventilated is provided, and the rotor is rotated via a friction part provided to an outer peripheral part. SOLUTION: A rotor 2 is provided by being impregnated with a moisture absorbent, and a toothed wheel 8 as a friction part is provided onto an outer peripheral edge surface. Further, a dehumidification air blower 9 and a dehumidification air passage 10 for ventilating air to be dehumidified, and a regeneration air blower 11 and a regeneration air passage 12 for ventilating air for regeneration of the moisture absorbent are provided before and behind a rotor 2, and a heater for regeneration 13 is arranged on the windward side of the rotor 2 in the regeneration air passage 12. Then, for the rotor 2, by providing a heat exchange surface so as to cross the dehumidification air passage 10 and the regeneration air passage 12, a shaft, a reinforcing material, a belt, a pulley, etc., become unnecessitated, and the rotor for dehumidifier can be on the whole constituted in a small size at a low cost.</p> |
