PROBLEM TO BE SOLVED: To prevent the deterioration in reliability of a device by restraining generation of a sound when switching the flowing direction of a refrigerant when adopting a method for carrying an adsorbent in heat exchangers 3 and 5 of a refrigerant circuit 1, and supplying adsorbing side or regenerating side air in a room while alternately switching the flowing direction of the refrigerant in a humidity controller for conditioning humidity of air by the adsorbent. SOLUTION: A plurality of opening closing valves 81, 83, 85 and 87 are used without using a four-way selector valve for switching the flowing direction of the refrigerant in the refrigerant circuit 1.
