Patent ID: 7874174

Claim:
A humidity control system comprising a plurality of adsorption elements allowing respective adsorbents carried on the respective surfaces thereof to come into contact with air and a regenerator for regenerating the adsorbents of the adsorption elements by heating, the humidity control system being configured to allow each said adsorption element to repeatedly perform an adsorption action of adsorbing moisture in a first air on the associated adsorbent and a regeneration action of regenerating the adsorbent with the regenerator to humidify a second air, the humidity control system being capable of a humidification operation of supplying the humidified second air to a room and exhausting the dehumidified first air to the outside, the humidity control system performing, during the humidification operation, a cooling action of cooling the second air humidified by one said adsorption element performing the regeneration action by allowing the second air to pass through another said adsorption element having already performed the previous adsorption action but having not yet performed the next regeneration action.
