Abstract

To provide an air conditioning system that offers superior efficiency in both the adsorption and regeneration modes of humidity control devices. [Solution] The air conditioning system comprises a flow path 10 through which indoor and / or outdoor air can flow, a humidity control device 20 disposed within the flow path 10 and capable of repeatedly performing an adsorption mode for adsorbing moisture and a regeneration mode for dewatering moisture, a control unit 40 capable of controlling the flow rate of air flowing through the flow path 10 and the humidity control device 20, and a humidity sensor 70 for measuring the relative humidity in the room. The control unit 40 monitors the relative humidity in the room using the humidity sensor 70 and controls at least one of the air flow rate and execution time in the regeneration mode and the adsorption mode according to changes in the relative humidity in the room.
