The flow path opening / closing means 82 is configured to be able to open and close the installation space for the B-side discharge path 75 and the outdoor fan 29.

When the flow path opening / closing means 82 is in the open state, the suction side discharge path 75 is opened in the negative pressure space generated by the outdoor fan 29, and the outdoor unit casing 8 is opened. An airflow is generated that passes through the humidification port 58 from the outside of the air conditioning unit 0 and is exhausted to the front of the outdoor air conditioning unit 5 through the adsorption-side discharge passage 75.

The peripheral surface of the nut member 96 constitutes a gear meshing with a gear 97 fixed to the rotating shaft 97 of the driving motor 98. The driving motor 98 is driven to rotate in one direction. As a result, the nut member 96 rotates via the gear 97, and the screw shaft 94 moves in the minus direction. At this time, the slide plate 92 to which one end of the screw shaft 94 is fixed is guided by the guide members 93, 93, and moves, for example, from a position where the opening 91 is closed to a position where it is opened. Similarly, by driving the drive motor 98 in the other direction, the screw shaft 94 moves in multiple directions. At this time, the slide plate 92 to which one end of the screw shaft 94 is fixed moves together with the screw shaft 94, and moves from a position where the opening 91 is opened to a position where it is closed.

[Other examples of channel opening / closing means]

(A) Another example of the flow path opening / closing means 82 is shown in FIG. Here, a slide plate 101 capable of opening and closing an opening 91 provided in the partition plate 81 is supported rotatably about a rotation shaft 102.

In this case, the amount by which the slide plate 101 opens the opening 91 can be adjusted by the driving amount of the driving mode.

(Humidification operation control)

(A) Opening control of channel opening / closing means by mode

When the flow path opening / closing means 82 capable of adjusting the opening degree is used, the opening degree can be controlled by the operation mode. Figure 9 shows the control method in this case.

As shown in FIG. 9, when the operation mode is the cooling operation or the heating operation, the channel opening / closing means 82 is set to the fully closed state. At this time, since the air flow passing through the humidification port 58 is shut off, the air flow generated by the outdoor fan 29 is only for the outdoor heat exchanger 24.

When the operation mode is the heating and humidification operation, the channel opening / closing means 82 is set to a half-open state. In this case, the airflow passing through the humidification port 58 is limited to half of that in the fully open state, and the airflow to the outdoor heat exchanger 24 is sufficiently ensured to improve the efficiency of the heating operation. Humidification operation by the humidification unit 3 can be performed without deteriorating the performance. Further, when the operation mode is the humidification operation, the opening degree of the flow path opening / closing means 82 is set to the fully open state. In this case, the air flow passing through the humidification flow path is maximized, and it becomes possible to efficiently adsorb moisture in the humidification operation.

(B) Humidifying operation control by outdoor fan control

In the humidification operation mode, it is conceivable to control the rotation speed of the outdoor fan 29 in accordance with the humidity of the outside air to adjust the amount of moisture adsorbed from the introduced air. A flowchart in this case is shown in FIG.

In step S11, the outside air humidity is detected. If the outdoor unit 3 is provided with a humidity sensor, the humidity sensor can detect the outside air humidity. If an outside air temperature sensor for detecting the outside air temperature and a temperature sensor for detecting the air temperature after passing through the humidifying low and evening are provided, the outside air temperature sensor and the low It can be configured to detect the outside air humidity from the detection value of the temperature sensor after the evening passage.

In step S12, it is determined whether the outside air humidity is lower than a first predetermined value. When it is determined that the outside air humidity is lower than the first predetermined value, the process proceeds to step S13. In step S13, the number of revolutions of the outdoor fan 29 is set high. Here, the outdoor fan motor 30 for driving the outdoor fan 29 is constituted by a DC motor, and the number of revolutions can be set high by increasing the power supply frequency supplied to the outdoor fan motor 30. It becomes possible.

In step S14, it is determined whether or not the outside air humidity is higher than a second predetermined value. The second predetermined value is set to a value larger than the first predetermined value. If the detected outside air humidity is higher than the second predetermined value, the process proceeds to step S15. In step S15, the rotation speed of the outdoor fan 29 is set low. Here, by setting the power supply frequency supplied to the outdoor fan motor 30 low, it is possible to set the rotation speed low.

(C) Humidification operation control by adjusting the degree of opening of the channel opening / closing means

If the channel opening / closing means 82 can be adjusted, in the humidification operation mode, it is conceivable to adjust the opening in accordance with the humidity of the outside air and change the amount of air introduced to adjust the amount of adsorbed moisture. Can be FIG. 11 shows a flowchart in this case. In step S21, the outside air humidity is detected. In the same manner as described above, it is possible to detect the outside air humidity by the humidity sensor installed in the outdoor unit 3, and to detect the outside air humidity from the detection values of the outside air temperature sensor and the temperature sensor after passing through the lowway. Can be configured.

In step S22, it is determined whether or not the outside air humidity is lower than a first predetermined value. When it is determined that the outside air humidity is lower than the first predetermined value, the process proceeds to step S23. In step S23, the opening degree of the flow path opening / closing means 82 is set large.

In step S24, it is determined whether or not the outside air humidity is higher than a second predetermined value. The second predetermined value is set to a value larger than the first predetermined value. If the detected outside air humidity is higher than the second predetermined value, the process proceeds to step S25. In step S25, the degree of enclosing of the channel enclosing means 82 is set small. The casing member and each component around the air outlet of the indoor unit 2 can be made of a synthetic resin mixed with tourmaline powder. In addition, a composition containing tourmaline powder may be applied to the casing member and each component. Furthermore, the inside of the humidification air pipe 7 from the humidification unit 4 to the indoor unit 2 and each component of the humidification unit 4 are made of synthetic resin containing tourmaline powder or coated with paint containing tourmaline powder. Is used.

Tourmaline generates negative ions by discharging when exposed to moisture. For this reason, a large amount of negative ions can be contained in the air blown from the indoor unit 2 of the indoor unit 2, thereby reducing the generation of active oxygen harmful to the human body and preventing adult diseases such as hypertension. be able to.
