First, when a user wants to use the air conditioner in a humidification mode, as shown in FIG. 2, both ends of the first flow path 61 are connected to the outdoor duct 57, and the operation unit (not shown). When the humidification mode is input through the damper 70, the damper 70 opens the fourth passage 64 and shields the third passage 63.
Accordingly, outdoor air flows into the first flow passage 61, and outdoor air flowed into the first flow passage 61 passes through the adsorption portion 51 of the desiccant wheel 50. After the moisture is dehumidified in the 51, the water is discharged again through the outdoor duct 57.
In addition, indoor air is introduced into the second passage 62, and the indoor air introduced into the second passage 62 is heated to a high temperature by the heater 54 while passing through the heater 54. .
The heated air passes through the humidifying part 52 of the desiccant wheel 50, thereby drying the humidifying part 52, thereby absorbing moisture from the humidifying part 52 and being humidified.

Here, the humidified air is introduced into the heat exchanger 53 through the inlet 53a, but the first flow path 61 passes through the lower side of the heat exchanger 53, but the first flow path There is no heat exchange with air passing through 53.
Therefore, the humidified air is discharged directly to the indoor side, the humidification of the room is made.
As such, when the air conditioner is used in the humidification mode, since the humidified air is not directly heat-exchanged inside the heat exchanger 53 but is discharged directly to the room, condensed water is not generated inside the heat exchanger 53. The drain pan 58 may not be used.
On the other hand, when the user wants to use the air conditioner in the dehumidification mode, as shown in Figure 3, the both ends of the first passage 61 is separated from the outdoor duct 57, the heat exchanger 53 The drain pan 58 is mounted to the bottom of the drain pan 58.
Thereafter, when the dehumidification mode is input through the operation unit (not shown), the damper 70 opens the third passage 63 and shields the fourth passage 64.
In addition, indoor air flows into the first flow passage 61, and the indoor air flowed into the first flow passage 61 passes through the adsorption portion 51 of the desiccant wheel 50. Moisture is dehumidified by the 51 and then discharged back into the room.
Therefore, since the dehumidified air is discharged to the room, dehumidification of the room is achieved.
In addition, indoor air flows into the second passage 62, and the indoor air introduced into the second passage 62 is heated to a high temperature by the heater 54 while passing through the heater 54.
Thereafter, humidified air is introduced into the fourth flow path 64 opened by the damper 70, and heat exchange with air in the first flow path 61 passing through the outside of the heat exchanger 53. This is done.
At this time, the air in the third flow path 63 is hot and humid, and since the indoor air in the first flow path 61 is cooler than the air in the third flow path 63, the air in the third flow path 63. Is condensed in the heat exchanger (53).
Since the water contained in the air in the third flow path 63 is condensed in the heat exchanger 53, the indoor air in the third flow path 63 is removed, the heat exchanger 53 The condensed water condensed therein is discharged to the drain pan 58 through the condensate drain port 53d of the heat exchanger 53.
Therefore, since the air from which moisture is removed is discharged back into the room through the first outlet 53b, dehumidification of the room is achieved.
As such, when the air conditioner is used as a dehumidifying function, only indoor air is used, so that the first passage 61 may be separated into the outdoor duct 57, and the air conditioner may be located anywhere in the room. Ena installation is possible.
