In addition, the fourth opening 35d is shielded by the third lower portion 32c of the partition portion 32. Therefore, the inner wall portion 36 communicates with the first opening 35a on the upper side and communicates with the third opening 35c on the lower side, thereby connecting the inside of the second switching portion casing 34 and the first intake / exhaust hose 6a. Therefore, the intake / exhaust duct 58 and the first intake / exhaust hose 6a communicate with each other. Thus, in the air supply state, as shown in FIG. 8B, the air that has passed through the intake / exhaust duct 58 passes through the inside of the first switching portion casing 33 and the inside of the second switching portion casing 34. The first intake / exhaust hose 6a is supplied from the third opening 35c. In the exhaust state, as shown in FIG. 8 (c), the air that has passed through the first intake / exhaust hose 6a passes through the third opening 35c and the first switching portion casing 34 and the first switching portion.

<Control unit>
As shown in FIG. 10, the control unit 60 is connected to various devices such as the indoor units 2a and 2b, the outdoor air conditioning unit 5 and the humidifying unit 4, and receives an operation command from the air conditioning target person via the remote controller 80 or the like. Based on this, operation control of various devices can be performed according to each operation mode such as normal operation, humidification operation, air supply operation, and exhaust operation.

  Hereinafter, the operation of the air conditioner 1 during each air conditioning operation will be described.

<Operation of air conditioner>
(1) Normal operation When the control unit 60 receives a normal operation instruction from a remote controller (hereinafter referred to as a remote controller) 80, the control unit 60 controls the operation of the air conditioner 1 so that the normal operation is performed.

  During normal operation, the compressor 21 is driven, and the outdoor expansion valves 25a and 25b are throttled to a predetermined opening, whereby the refrigerant circulates through the refrigerant circuit and the indoor heat exchangers 11a and 11b are evaporators or condensers. It functions as a vessel. Further, when the indoor fans 12a and 12b are driven, the indoor fans 12a and 12b are sucked into the indoor units 2a and 2b from the air intake port, and then blown into the room through the indoor heat exchangers 11a and 11b. An air flow is generated. Thereby, cooling or heating in the rooms 1a and 1b can be performed.

(2) Humidification operation When receiving a humidification command from the remote controller 80, the control unit 60 controls the operation of the air conditioner 1 so that the humidification operation is performed. This humidification operation is often performed together with the heating operation. When the humidifying operation is performed in both the first indoor unit 2a and the second indoor unit 2b, the control unit 60 drives the partition unit driving motor 42 so that the air flow path switching unit 30 is in the first state. Let When the humidifying operation is performed only with the first indoor unit 2a, the control unit 60 drives the partition unit driving motor 42 so that the air flow path switching unit 30 is in the second state. Further, when the humidifying operation is performed only by the second indoor unit 2b, the control unit 60 drives the partition unit driving motor 42 so that the air flow path switching unit 30 is in the third state.

  Hereinafter, a case where the humidifying operation is performed in both the first indoor unit 2a and the second indoor unit 2b will be described as an example.

The control unit 60 controls the heating device 52 to be energized.

  When the suction fan motor 59 is driven, outdoor air is taken into the humidifying unit 4 and discharged outside. That is, the air from the outside is taken into the humidification unit casing 7 from the adsorption air intake port 7b. The air that has entered the humidifying unit casing 7 passes through a portion of the humidifying rotor 51 that does not face the heating device 52. At this time, the humidification rotor 51 adsorbs moisture from the air passing through the adsorption position of the humidification rotor 51. The air that has passed through the humidification rotor 51 is folded downward and discharged from the adsorption air outlet 7a to the outside of the outdoor unit.

  On the other hand, when the humidifying fan 54 is driven, outdoor air is taken into the humidifying unit 4 and supplied into the rooms 1a and 1b through the intake / exhaust hoses 6a and 6b and the indoor units 2a and 2b. That is, outdoor air is taken into the humidification unit casing 7 from the intake / exhaust port 7c, passes through the humidification rotor 51 from the lower side to the upper side, is heated by the heating device 52, and then passes through the humidification rotor 51 from the upper side to the lower side. To pass through. At this time, the moisture adsorbed on the humidification rotor 51 is excited and is released from the humidification rotor 51 into the air. The air that has passed through the humidification rotor 51 passes through the humidification fan 54, the intake / exhaust switching damper 53, and the air flow path switching unit 30, and is sent to the intake / exhaust hoses 6a and 6b. The air sent to the intake / exhaust hoses 6a and 6b passes through the indoor heat exchangers 11a and 11b and is blown out into the rooms 1a and 1b from the air outlet. The air sent to the indoor units 2a and 2b contains the moisture adsorbed by the humidification rotor 51, thereby enabling humidification of the room without water supply.

  In this humidification operation, the moisture contained in the air introduced into the humidification unit 4 from the outside by the rotation of the adsorption fan 61 is adsorbed to the humidification rotor 51, and the air heated by the heating device 52 is rotated by the rotation of the humidification fan 54. The air containing moisture separated from the humidification rotor 51 is supplied to the indoor units 2a and 2b via the intake / exhaust duct 58, the air flow path switching unit 30, and the intake / exhaust hoses 6a and 6b. is doing.

(3) Air Supply Operation When the control unit 60 receives an instruction for the air supply operation from the remote controller 80, the control unit 60 controls the operation of the air conditioner 1 so that the air supply operation is performed.

  When the air supply operation is performed, the suction fan motor 59 is not operated, and the heating device 52 is not energized, and the same operation as the humidification operation described above is performed. Thereby, the air taken in from the outside is sent to the indoor units 2a and 2b through the same path as described above without being humidified.

(4) Exhaust operation When receiving an exhaust operation instruction from the remote controller 80, the control unit 60 controls the operation of the air conditioner 1 so that the exhaust operation is performed. When exhaust operation is performed in both the first indoor unit 2a and the second indoor unit 2b, the control unit 60 drives the partition unit drive motor 42 so that the air flow path switching unit 30 is in the first state. Let When the exhaust operation is performed only with the first indoor unit 2a, the control unit 60 drives the partition unit drive motor 42 so that the air flow path switching unit 30 is in the second state. Further, when the exhaust operation is performed only by the second indoor unit 2b, the control unit 60 drives the partition unit drive motor 42 so that the air flow path switching unit 30 is in the third state.

  Hereinafter, a case where the exhaust operation is performed in both the first indoor unit 2a and the second indoor unit 2b will be described as an example.

  The control unit 60 controls the intake / exhaust switching damper 53 to switch to the exhaust state and the air flow path switching unit 30 to switch to the first state, and drives the motor that rotates the humidifying fan 54. During the exhaust operation, the suction fan motor 59 is not driven and the heating device 52 is not energized.

  When the humidifying fan 54 is driven, the air in the rooms 1a and 1b taken in from the indoor units 2a and 2b is taken into the humidifying unit 4 through the intake and exhaust hoses 6a and 6b, and during the humidification operation described above. Is discharged outside by flowing in the opposite direction. That is, the air taken into the humidifying unit main body 6 from the intake / exhaust duct 58 passes through the air flow switching unit 30, the intake / exhaust switching damper 53, the humidifying fan 54, and passes through the humidifying rotor 51 from below to above. It is discharged from the intake / exhaust port 7c to the outside.

When the humidifying operation is performed only with the first indoor unit 102a, the control unit 160 drives the damper drive motor 142 so that the air flow path switching unit 130 is in the second state. Furthermore, when the humidifying operation is performed only by the second indoor unit 102b, the control unit 160 drives the damper drive motor 142 so that the air flow path switching unit 130 is in the third state.

  Hereinafter, a case where the humidifying operation is performed in both the first indoor unit 102a and the second indoor unit 102b will be described as an example.

  The control unit 160 controls the intake / exhaust switching damper 153 to switch to the air supply state and the air flow path switching unit 130 to switch to the first state, and drives the motor that rotates the humidifying fan 154 and the suction fan motor 159. . In addition, the control unit 160 controls the heating device 152 to be energized.

  When the suction fan motor 159 is driven, outdoor air is taken into the humidifying unit 104 and discharged outside. That is, the air from the outside is taken into the humidification unit casing 107 from the adsorption air intake 107b. The air that has entered the humidifying unit casing 107 passes through a portion of the humidifying rotor 151 that does not face the heating device 152. At this time, the humidification rotor 151 adsorbs moisture from the air passing through the adsorption position of the humidification rotor 151. The air that has passed through the humidifying rotor 151 is folded downward and discharged from the adsorption air outlet 107a to the outside of the outdoor unit.

  On the other hand, when the humidifying fan 154 is driven, outdoor air is taken into the humidifying unit 104 and supplied to the rooms 101a and 101b through the intake / exhaust hoses 106a and 106b and the indoor units 102a and 102b. That is, outdoor air is taken into the humidifying unit casing 107 from the intake / exhaust port 107c, passes through the humidifying rotor 151 from below to above and heated by the heating device 152, and then passes through the humidifying rotor 151 from above. To pass through. At this time, the moisture adsorbed on the humidification rotor 151 is excited and desorbs from the humidification rotor 151 into the air. The air that has passed through the humidifying rotor 151 passes through the humidifying fan 154, the intake / exhaust switching damper 153, and the air flow path switching unit 130, and is sent to the intake / exhaust hoses 106a and 106b. The air sent to the intake / exhaust hoses 106a, 106b passes through the indoor heat exchangers 111a, 111b and is blown out into the rooms 101a, 101b from the air outlets. The air sent to the indoor units 102a and 102b includes the moisture adsorbed by the humidification rotor 151, thereby enabling humidification in the room without supplying water.

  In this humidification operation, moisture contained in the air introduced into the humidification unit 104 from the outside by the rotation of the adsorption fan 161 is adsorbed to the humidification rotor 151 and the air heated by the heating device 152 is rotated by the rotation of the humidification fan 154. The air containing moisture separated from the humidification rotor 151 is supplied to the indoor units 102a and 102b via the intake / exhaust duct 158, the air flow path switching unit 130, and the intake / exhaust hoses 106a and 106b. is doing.

(3) Air Supply Operation When the controller 160 receives an instruction for the air supply operation from the remote controller 180, the controller 160 controls the operation of the air conditioner 100 so that the air supply operation is performed.

  When the air supply operation is performed, the suction fan motor 159 is not operated, and the heating device 152 is not energized, and the same operation as the humidification operation described above is performed. Thereby, the air taken in from the outside is sent to the indoor units 102a and 102b through the same path as described above without being humidified.

(4) Exhaust operation When receiving an exhaust operation instruction from the remote controller 180, the control unit 160 controls the operation of the air conditioner 100 so that the exhaust operation is performed. When the exhaust operation is performed in both the first indoor unit 102a and the second indoor unit 102b, the control unit 160 drives the damper drive motor 142 so that the air flow path switching unit 130 is in the first state. . When the exhaust operation is performed only by the first indoor unit 102a, the control unit 160 drives the damper drive motor 142 so that the air flow path switching unit 130 is in the second state. Further, when the exhaust operation is performed only by the second indoor unit 102b, the control unit 160 drives the damper drive motor 142 so that the air flow path switching unit 130 is in the third state.

  Hereinafter, a case where the exhaust operation is performed in both the first indoor unit 102a and the second indoor unit 2b will be described as an example.

  The control unit 160 controls the intake / exhaust switching damper 153 to switch to the exhaust state and the air flow path switching unit 130 to switch to the first state, and drives the motor that rotates the humidifying fan 154. During the exhaust operation, the suction fan motor 159 is not driven and the heating device 152 is not energized.

  When the humidifying fan 154 is driven, the air in the rooms 101a and 101b taken in from the indoor units 102a and 102b is taken into the humidifying unit 104 via the intake and exhaust hoses 106a and 106b, and during the humidifying operation described above. Is discharged outside by flowing in the opposite direction. That is, the air taken into the humidifying unit main body 106 from the intake / exhaust duct 158 passes through the air flow switching unit 130, the intake / exhaust switching damper 153, the humidifying fan 154, and passes through the humidifying rotor 151 from below to above. It is discharged from the intake / exhaust port 107c to the outside.

  In the present embodiment, the air supply operation or the exhaust operation is performed on the two rooms 101a and 101b, but the air supply operation and the exhaust operation are performed on two or more rooms. An air flow path switching unit may be configured.

<Features>
(1)
In the above embodiment, the air flow path switching unit 130 is disposed outside the humidification unit casing 107. For this reason, compared with the case where the air flow path switching part 130 is arrange | positioned in the humidification unit casing 107, the size of the humidification unit 104 can be made small.

  Thereby, the size of the outdoor unit 103 can be reduced.

(2)
In the above embodiment, a pipe having a pipe diameter larger than the pipe diameter of the pipe applied to the intake / exhaust hoses 106a and 106b is applied to the intake / exhaust duct 158. For this reason, the pressure loss in the intake / exhaust duct 158 can be suppressed.

  Further, during the humidification operation, the humid air passes through the intake / exhaust duct 158. In this air conditioner 100, since the pressure loss in the intake / exhaust duct 158 is reduced, humidified air can hardly be condensed in the intake / exhaust duct 158.

  Since the present invention can realize air supply into a plurality of rooms by one air supply unit, application to an air conditioner is effective.
