  With the above configuration, the microcomputer (not shown) inside the motor / humidification control means 1 has a predetermined value of 40% humidity, and the bathroom humidity sensor 17 controls the humidity of the bathroom inside the motor / humidification control means 1 ( (Not shown) and the outdoor humidity is 40% or more, the water supply valve 3 is closed, the bathroom humidified air conveying means 15 operates, the humidified air in the bathroom is supplied to the room 112, and the humidity in the room 112 is Can be raised.

(Embodiment 11)
The same parts as those in the conventional example and the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 14, the air conditioner includes a suction air volume control means 18 that controls the blower air volume of the blower unit to be smaller than the suction air volume of the suction unit when the humidity in the room 112 reaches a predetermined value or more. ing.

  Next, a control flowchart of the suction air volume control means 18 will be described with reference to FIG.

  As shown in the figure, the suction air volume control means 18 inputs the blow air volume of the blow unit 109 and the suction air volume of the suction unit 108. The deviation between the input blown air volume and the intake air volume is calculated, and if the blown air volume is smaller than the intake air volume, the process is terminated. When the blown air volume is larger than the intake air volume, the deviation at that time is input to the proportional-plus-integral controller, and control is performed so as to decrease the rotational speed of the blower fan 106. When the rotational speed command value of the blower fan 106 is lower than a predetermined lower limit value, that is, 10% of the rated rotational speed, it is fixed at the lower limit value, and the opening degree of the damper BOX 6 is controlled to be lowered.

  With the above configuration, the overshoot control of the humidification amount in the room 112 can be returned at a higher speed.

  The predetermined lower limit value of the rotational speed is 10% of the rated rotational speed, but other rotational speeds that can maintain the accuracy of air flow control of the blower fan 106 may be used.

(Embodiment 12)
The same parts as those in the conventional example and the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 16, when the humidity in the room 112 is lower than a predetermined value, for example, relative humidity 40%, the air conditioner is controlled so as to switch the air path with priority given to the transfer of moisture from the bathroom to the room 112. The branch control means 19 is provided.

  Next, a control flowchart of the branch control means 19 will be described with reference to FIG.

  As shown in the figure, the branch control means 19 inputs the humidity in the room 112. The input humidity is stored in the storage unit 14a and processed as time series data. The moving average of the humidity of the room 112 acquired at 1 minute intervals as time series data is calculated, and the oldest data is overwritten when new data is input. The calculated moving average value of the humidity in the room 112 is stored in the average value storage unit 14b, and the processing is exited when the average value is higher than the threshold value as compared with the moving average value stored in time series and the humidity threshold value. When the average value is lower than the predetermined threshold value, the air path is controlled to be switched.

  With the above configuration, the room 112 can be controlled to an optimum humidity at a higher speed by using moisture in the bathroom.

  Although the time-series data is 1 minute intervals, other time intervals may be used.

  Further, although the moving average is calculated and the humidity threshold is determined based on the moving average, the humidity threshold may be determined from the instantaneous value.

  The present invention can also be applied to a system that air-conditions the entire building such as an air conditioner that branches off by a blower duct or a suction duct and that simultaneously air-conditions a plurality of rooms.
