Patent ID: 6959875

Claim:
A humidity control apparatus comprising: a plurality of adsorbing elements including a humidity-control-side passage for bringing circulating air into contact with an adsorbent; and a heater for heating air supplied to the humidity-control-side passage of the adsorbing elements for regenerating the adsorbent, the humidity control apparatus carrying out an adsorbing operation for introducing first air into the humidity-control-side passage of the adsorbing elements to cause the adsorbent to adsorb moisture in the first air and a regenerating operation for introducing second air which has been heated in the heater into the humidity-control-side passage of the adsorbing elements to desorb the moisture from the adsorbent, the second air being formed of a mixture of room air and outside air, and the adsorbing elements further including a cooling-side passage through which cooling fluid absorbs heat of adsorption generated in the humidity-control-side passage during the adsorbing operation.
