- step S122 the controller 150 specifies the required humidification amount of the living room 102a as the humidity difference between the living room humidity obtained from the living room humidity sensor 112a and the living room set humidity set for the living room 102a.
- the room set humidity and the room humidity are each converted into absolute humidity, and the value obtained by subtracting the room absolute humidity from the room set absolute humidity is defined as the required humidification amount. This means that the larger the positive value of the required humidification amount, the more humidification is required in the living room 102a.

- the controller 150 sets the required rotational speed higher as the required humidification amount is higher, the suction temperature is lower, or the total air volume of the transfer fan 103 is smaller.
- the controller 150 identifies the required rotation speed based on the humidification performance data of the humidifier 116 shown in FIG.
- the humidification performance data is data obtained in advance by experiments, and the humidification performance data generated by the humidification device 116 when the humidification operation is performed under the conditions of the suction temperature T, the rotation speed R of the pumping pipe 137, and the total air volume Q of the transfer fan 103.
- Quantity X is shown.
- the amount of humidification X produced by the humidifier 116 corresponds to the amount of water contained in the air flowing through the humidifier 116 . Due to the characteristics of the humidifier 116, the suction temperature T, the number of revolutions R, and the total air volume Q have a positive correlation with the humidification amount X, respectively. For example, when the total air volumes Q1 and Q2 are in the relationship of Q1 ⁇ Q2, and the temperature is T1 and the rotational speed is R1, the relative magnitude of the humidification amounts X1 and X2 is X1 ⁇ X2.
- the regression formula of formula (1) is a combination of linear terms of the rotation speed R, the suction temperature T, and the total air volume Q, in order to improve the accuracy of the regression, the rotation speed R, the suction temperature T, and the total air volume Q any second or higher term may be included.

- the lower limit number of rotations is specified as the number of rotations of the pumping pipe 137 (step S127).
- the required rotation speed exceeds the upper limit rotation speed, it means that the amount of humidification that can be output at the upper limit rotation speed is insufficient for the required humidification amount. Further, when the required rotation speed is lower than the lower limit rotation speed, it means that the amount of humidification that can be output at the lower limit rotation speed is excessive with respect to the required humidification amount.
- FIG. 16 is a flow chart showing the conveying fan air volume correction processing of the controller 150 .
- step S132 the controller 150 increases the total air volume Q of the transfer fan 103 by a predetermined rate (eg, 1.1 times) (step S132). If the required rotation speed is equal to or lower than the upper limit rotation speed (NO in step S131), it is determined whether the required rotation speed is lower than the lower limit rotation speed (step S133). If the required rotation speed is lower than the lower limit rotation speed (YES in step S133), the total air volume Q of the carrier fan 103 is decreased by a predetermined rate (for example, 0.9 times) (step S134).
- a predetermined rate eg, 1.1 times
- the air volume blown by the air conditioner 113 is adjusted according to the air volume correction of the carrier fan 103. Increase or decrease to equal the total airflow of fan 103 . By doing so, the amount of air flowing into the humidifier 116 can be changed without changing the temperature of the air sucked into the humidifier 116 . As a result, when the amount of humidification that can be output at the upper limit rotation speed is lower than the required amount of humidification, the amount of air to be conveyed to each living room 102 is increased.
- the total air volume Q of the carrier fan 103 after correction is obtained by solving the equation (1) for the total air volume Q, the humidification amount X being the required humidification amount of the general house 101, the rotation speed R being the upper limit rotation speed, and the suction temperature T being the suction temperature. You may specify by substituting and calculating as the suction temperature from the temperature sensor 114, respectively.

加湿制御を開始すると、図5に示すように、コントローラ50は、被空調空間である居室2の室数分のループを開始する(ステップS21)。そして、コントローラ50は、被空調空間である居室2a~2dのそれぞれに対する要求加湿量を算出する(ステップS22)。そして、コントローラ50は、すべての居室2の要求加湿量の算出が完了したらループを終了する(ステップS23)。
次に、図6~図9を参照して、居室湿度センサ12a~12dが外乱により急激な湿度変化が発生した場合のコントローラ50の処理動作を説明する。図6は、外乱による湿度変化を検出した時のコントローラ50の第一処理動作を示すフローチャート図である。図7は、外乱による湿度変化を検出した時のコントローラ50の第二処理動作を示すフローチャート図である。図8は、外乱による湿度変化を検出した時のコントローラ50の第三処理動作を示すフローチャート図である。図9は、外乱による湿度変化を検出した時のコントローラ50の第四処理動作を示すフローチャート図である。
