PROBLEM TO BE SOLVED: To expand a capacity control range, in a humidity controller including a refrigerant circuit to which an adsorption heat exchanger is connected. SOLUTION: An air-conditioning system 10 as the humidity controller is provided with: an outdoor unit 11; a humidity control unit 12; an air-conditioning unit 14; and a connection unit 16. In the refrigerant circuit 20 of the air-conditioning system, an outdoor circuit 30 is connected to humidity control circuits 40, 50 and air-conditioning circuits 60, 70 through high pressure gas piping 21, low pressure gas piping 22 and high pressure liquid piping 23. In the humidity control circuits, first expansion valves 43, 53 and second expansion valves 44, 54 are respectively disposed between first adsorption heat exchangers 41, 51 and second adsorption heat exchangers 42, 52. Four-way switch valves 45, 55 of the humidity control circuits are connected to the high pressure gas piping and the low pressure gas piping. In the humidity control circuits, parts respectively between the first expansion valve and the second expansion valve are connected to the high pressure liquid piping through liquid circulation pipes 46, 56.
