Claim:
1. An air-conditioning system comprising: at least one outdoor unit including a compressor, a flow switching device, and an outdoor heat exchanger; at least one indoor unit including a first expansion device and a first indoor heat exchanger; and at least one humidity control device including a second expansion device, a second indoor heat exchanger, a humidity control device air-sending device, a first water adsorption/desorption device, and a second water adsorption/desorption device, wherein the compressor, the flow switching device, the outdoor heat exchanger, the first expansion device, the first indoor heat exchanger, the second expansion device, and the second indoor heat exchanger are connected to each other with pipes so as to constitute a refrigerant circuit, wherein, in the humidity control device, the first water adsorption/desorption device and the second water adsorption/desorption device are disposed in an air path providing communication between an air inlet through which air flows in from a humidity controlled space and an air outlet through which air flows out into the humidity controlled space, the first water adsorption/desorption device and the second water adsorption/desorption device each comprising a dehumidification element including an adsorbent whose equilibrium adsorption capacity with respect to air having a relative humidity in a range of 40% through 100% increase with an increase in the relative humidity, the second indoor heat exchanger is disposed between the first water adsorption/desorption device and the second water adsorption/desorption device in the air path, wherein the humidity control device further includes a switching device that switches between a first channel in which the air that has flowed in through the air inlet is caused to pass through the first water adsorption/desorption device, the second indoor heat exchanger, and the second water adsorption/desorption device in this order, and a second channel in which the air that has flowed in through the air inlet is caused to pass through the second water adsorption/desorption device, the second indoor heat exchanger, and the first water adsorption/desorption device in this order, and wherein the humidity control device air-sending device is configured to vary a volume of air and send the varied volume of air to the first water adsorption/desorption device and the second water adsorption/desorption device, and wherein, during a cooling operation, the humidity control device is configured to dehumidify air inhaled from the humidity controlled space and supply the air which was dehumidified to the humidity controlled space from where the air was inhaled.
