A first embodiment of the present invention will be described. The humidity control device (10) of this embodiment is configured to be capable of performing a dehumidification operation for supplying dehumidified air to the room and a humidification operation for supplying humidified air to the room.
[0051] The humidity regulating device (10) includes a refrigerant circuit (50). As shown in Figure 1, the refrigerant circuit (50) is a closed circuit, provided with a first adsorption heat exchanger (51), a second adsorption heat exchanger (52), a compressor (53), a four-way reversing valve (54) and electric expansion valve (55). The refrigerant circuit (50) performs a vapor compression refrigeration cycle by circulating the refrigerant filled therein. The refrigerant circuit (50) constitutes a heat source mechanism.
[0052] In the refrigerant circuit (50), the discharge side of the compressor (53) is connected to the first valve port of the four-way reversing valve (54), an...

[0104] The action of the controller (90) in this embodiment in state S3 is different from that of the first embodiment. Other actions of the controller (90) are the same as those of the first embodiment. In state S3, the controller (90) shortens the time interval for switching between the first action and the second action. For example, the controller (90) shortens the switching interval, which was three minutes until then, to two minutes. In this example, in the refrigerant circuit (50), the switching interval between the first refrigeration cycle operation and the second refrigeration cycle operation is shortened from three minutes to two minutes.
[0105] Here, the amount of moisture exchanged between the adsorption heat exchangers (51, 52) and the air flowing through the adsorption heat exchangers (51, 52) is immediately after the operation of the first refrigeration cycle and the operation of the second refrigeration cycle are switched to each other. There are more in t...

A fifth embodiment of the present invention will be described. In this embodiment, the operation of the controller (90) is changed in the first embodiment. Here, the operation of the controller (90) of this embodiment will be described.
[0109] During the operation of the humidity control device (10), the controller (90) compares the actual measured value of the indoor temperature with the set value of the indoor temperature, for example, every few minutes. During the dehumidification operation, when the actual measured value of the indoor temperature is higher than the set value, and during the humidification operation, when the actual measured value of the indoor temperature is lower than the set value, the controller (90) extends the mutual Toggles the time interval between the first action and the second action. For example, the controller (90) extends the switching interval, which was three minutes at the time, to four minutes. In this example, in the refrigerant circu...
