　（３）気流制御システムの動作
　（３．１）気流吹出装置の動作
　気流吹出装置１では、ファン３の回転体３１及び複数の羽根３２が所定の回転方向Ｒ１（図３Ａ参照）に回転することにより、筒体２の流入口２３側からファン３に空気が吸い込まれ、筒体２内においてファン３の下流側に、筒体２内を筒体２の内周面２７に沿って旋回する気流Ｆ１（図３Ａ参照）が発生する。旋回する気流Ｆ１は、３次元の螺旋状に回転する気流である。 (3) Operation of Airflow Control System (3.1) Operation of Airflow Blowing Device In the airflow blowing device 1, the rotating body 31 and the plurality of blades 32 of the fan 3 rotate in a predetermined rotation direction R1 (see FIG. 3A). As a result, air is sucked into the fan 3 from the inlet 23 side of the cylindrical body 2, and the airflow swirls inside the cylindrical body 2 along the inner peripheral surface 27 of the cylindrical body 2 to the downstream side of the fan 3 in the cylindrical body 2. F1 (see FIG. 3A) occurs. The swirling airflow F1 is an airflow rotating in a three-dimensional spiral.
　気流吹出装置１では、ファン３の下流側に発生して筒体２の内周面２７の近くを内周面２７に沿って旋回する気流Ｆ１（図３Ａ参照）は、第１整流装置４において第１整流装置４の中心軸４０に近づく方向に転向される。より詳細には、第１整流装置４では、筒体２の内周面２７に沿って旋回していた気流Ｆ１（図３Ａ参照）がフィン４２に衝突することにより、第１整流装置４の中心軸４０に近づく気流Ｆ２（図３Ｂ参照）に転向される。言い換えれば、第１整流装置４は、ファン３により発生して筒体２の内周面２７に沿って旋回している気流Ｆ１を第１整流装置４の中心軸４０側に集めるので、第１整流装置４の下流側において第１領域の気流の速度が第２領域の気流の速度よりも速い流速分布を形成する。要するに、気流吹出装置１では、第１整流装置４によって、内側の気流の速度が相対的に速く外側の気流の速度が相対的に遅い速度分布を形成することができる。ここにおいて、気流の速度は、ファン３の軸方向Ｄ３に沿った方向の速度である。第１領域は、筒体２の中心軸２０と筒体２の内周面２７との間で中心軸２０に近い領域（内側領域）であり、第２領域は、筒体２の中心軸２０と筒体２の内周面２７との間で内周面２７に近い領域（外側領域）である。 In the airflow blowing device 1, the airflow F1 (see FIG. 3A) generated on the downstream side of the fan 3 and swirling along the inner peripheral surface 27 of the cylinder 2 near the inner peripheral surface 27 is It is turned in a direction approaching the central axis 40 of the first straightening device 4 . More specifically, in the first straightening device 4, the airflow F1 (see FIG. 3A) swirling along the inner peripheral surface 27 of the cylindrical body 2 collides with the fins 42, causing the center of the first straightening device 4 to It is turned into airflow F2 (see FIG. 3B) approaching axis 40 . In other words, the first straightening device 4 gathers the airflow F1 generated by the fan 3 and swirling along the inner peripheral surface 27 of the cylindrical body 2 toward the central axis 40 of the first straightening device 4. On the downstream side of the rectifier 4, a flow velocity distribution is formed in which the velocity of the airflow in the first area is higher than the velocity of the airflow in the second area. In short, in the airflow blowing device 1, the first rectifying device 4 can form a velocity distribution in which the velocity of the inner airflow is relatively high and the velocity of the outer airflow is relatively low. Here, the speed of the airflow is the speed in the direction along the axial direction D3 of the fan 3 . The first region is a region (inner region) near the central axis 20 between the central axis 20 of the cylindrical body 2 and the inner peripheral surface 27 of the cylindrical body 2, and the second region is the central axis 20 of the cylindrical body 2. and the inner peripheral surface 27 of the tubular body 2 (outer region) near the inner peripheral surface 27 .
　気流吹出装置１では、第１整流装置４の下流側の第２整流装置５により、第１整流装置４側からの気流の向きがファン３の軸方向Ｄ３に沿った方向に整流される。 In the airflow blowing device 1 , the direction of the airflow from the first straightening device 4 side is straightened along the axial direction D<b>3 of the fan 3 by the second straightening device 5 downstream of the first straightening device 4 .
　気流吹出装置１では、第２整流装置５により整流された気流が筒体２の流出口２４から流出する。 In the airflow blowing device 1 , the airflow rectified by the second rectifier 5 flows out from the outlet 24 of the cylinder 2 .
　気流吹出装置１では、ファン３が駆動されると、ファン３の下流側に流れる気流が、第１整流装置４及び第２整流装置５により整流され、筒体２の流出口２４から吹き出される。 In the airflow blowing device 1, when the fan 3 is driven, the airflow flowing downstream of the fan 3 is rectified by the first rectifier 4 and the second rectifier 5, and is blown out from the outlet 24 of the cylinder 2. .
　図５Ａは、気流吹出装置１の筒体２の流出口２４近傍での流速分布を示す。図５Ａは、実施形態１に係る気流制御システム１００における気流吹出装置１において、ファン３の風量を７０ｍ３／ｈとし、構造パラメータを下記の通りに設定した場合の流速分布を示す。また、図５Ｂは、第１整流装置４及び第２整流装置５を備えていない比較例に係る気流吹出装置での流速分布を示す。

　図５Ａ及び５Ｂの各々は、筒体２の中心軸２０を含む一断面での流速分布を示している。図５Ａ及び５Ｂの各々では、横軸が、筒体２の中心軸２０からの距離であり、縦軸が流速である。なお、横軸に関して、中心軸２０を中心として右側が「正」、左側が「負（－符号）」となっているが、「正」と「負（－符号）」は、中心軸２０の位置に対して右側の任意の位置までの距離か、左側の任意の位置までの距離かを区別するために付した符号である。 FIG. 5A shows the flow velocity distribution in the vicinity of the outlet 24 of the cylindrical body 2 of the airflow blowing device 1. FIG. FIG. 5A shows the flow velocity distribution when the air volume of the fan 3 is 70 m 3 /h and the structural parameters are set as follows in the airflow blowing device 1 in the airflow control system 100 according to the first embodiment. Also, FIG. 5B shows the flow velocity distribution in an airflow blowing device according to a comparative example that does not include the first straightening device 4 and the second straightening device 5 .
<Structural parameters>

Each of FIGS. 5A and 5B shows the flow velocity distribution in one section including the central axis 20 of the tubular body 2. FIG. 5A and 5B, the horizontal axis is the distance from the central axis 20 of the cylinder 2, and the vertical axis is the flow velocity. Regarding the horizontal axis, the right side of the central axis 20 is "positive" and the left side is "negative (- sign)". This is a code attached to distinguish between the distance to an arbitrary position on the right side of the position and the distance to an arbitrary position on the left side of the position.
　比較例に係る気流吹出装置では、図５Ｂに示すように、流出口２４の中心から離れるほど流速が速くなっている。これに対して、実施形態１に係る気流制御システム１００における気流吹出装置１では、図５Ａに示すように、流出口２４の内側領域での流速が外側領域での流速よりも速くなる流速分布を実現できている。気流吹出装置１では、流出口２４の内側領域から噴出する第１噴流と、流出口２４の外側領域から噴出する第２噴流と、を含む二重の噴流を吹き出すことが可能となる。 In the airflow blowing device according to the comparative example, as shown in FIG. 5B, the flow velocity increases with increasing distance from the center of the outflow port 24 . On the other hand, in the airflow blowing device 1 in the airflow control system 100 according to the first embodiment, as shown in FIG. It has been realized. The airflow blowing device 1 is capable of blowing out a double jet including a first jet from the inner region of the outlet 24 and a second jet from the outer region of the outlet 24 .
　気流吹出装置１では、筒体２の流出口２４から吹き出す気流（噴流）の指向性を高めることが可能となり、気流の拡散を抑制することが可能となる。よって、気流吹出装置１では、対象空間内の特定のエリアに、スポット的（局所的）に気流を搬送することが可能となる。 With the airflow blowing device 1, it is possible to increase the directivity of the airflow (jet flow) blown out from the outlet 24 of the cylindrical body 2, and to suppress the diffusion of the airflow. Therefore, with the airflow blowing device 1, it is possible to carry the airflow spotwise (locally) to a specific area in the target space.
　（３．２）制御部の動作
　制御部８は、例えば、流出口２４から吹き出す気流の速度（例えば、流出口２４の内側領域から噴出する第１噴流の速度）をゆらぎ制御し（図６参照）、気流の速度が閾値Ｖ１（図６参照）よりも大きいときに供給装置７から気流に機能成分を供給させる。「気流の速度をゆらぎ制御し」とは、気流の速度の時間変化がゆらぎ特性を有するように気流の速度を制御することを意味する。ゆらぎ特性は、例えば、１／ｆゆらぎ特性である。この場合、制御部８は、気流の速度の変化が１／ｆゆらぎの波形になるように気流の速度を制御することを意味する。「１／ｆゆらぎ」とは、パワースペクトル密度が周波数ｆに反比例するゆらぎを意味する。ゆらぎ特性は、１／ｆゆらぎに限らず、例えば、１／ｆ２ゆらぎであってもよい。また、ゆらぎ特性は、不規則なゆらぎ特性（例えば、１／ｆゆらぎ又は１／ｆ２ゆらぎ）に限らず、規則的なゆらぎであってもよい。 (3.2) Operation of Control Unit The control unit 8 controls the fluctuation of the speed of the airflow blown out from the outlet 24 (for example, the speed of the first jet flowed out from the inner region of the outlet 24) (see FIG. 6). ), causing the supply device 7 to supply the functional component to the airflow when the velocity of the airflow is greater than the threshold value V1 (see FIG. 6). The expression "fluctuation control of the airflow velocity" means controlling the airflow velocity such that the time change of the airflow velocity has fluctuation characteristics. The fluctuation characteristics are, for example, 1/f fluctuation characteristics. In this case, it means that the controller 8 controls the airflow velocity so that the change in the airflow velocity becomes a 1/f fluctuation waveform. "1/f fluctuation" means fluctuation in which the power spectral density is inversely proportional to the frequency f. The fluctuation characteristic is not limited to 1/f fluctuation, and may be, for example, 1/ f2 fluctuation. Moreover, the fluctuation characteristics are not limited to irregular fluctuation characteristics (for example, 1/f fluctuation or 1/ f2 fluctuation), and may be regular fluctuation.
　制御部８は、供給装置７から気流に機能成分を供給させる場合、気流に機能成分を一時的（瞬間的）に供給させる。 When supplying the functional component from the supply device 7 to the airflow, the control unit 8 temporarily (instantaneously) supplies the functional component to the airflow.
　制御部８は、流出口２４から吹き出す気流の速度が閾値Ｖ１である第１閾値Ｖ１よりも大きな第２閾値Ｖ２以下のときに供給装置７から気流へ機能成分を供給させることを許可する。図６は、流出口２４から吹き出す気流の速度の時間変化を示している。図６では、横軸が時間であり、縦軸が気流の速度である。制御部８は、気流の速度をゆらぎ制御することにより、例えば、気流の速度を第１速度ＶＬ以上第２速度ＶＨ以下の範囲で変化させる。第２速度ＶＨは、第１速度ＶＬよりも大きい。第１速度ＶＬは、例えば、０．０５ｍ／ｓｅｃである。第２速度ＶＨは、例えば、１．５ｍ／ｓｅｃである。第１閾値Ｖ１は、機能成分が気流に乗って対象空間に届くように決められており、例えば、１．０ｍ／ｓｅｃである。また、第２閾値Ｖ２は、例えば、１．６ｍ／ｓｅｃである。第１閾値Ｖ１及び第２閾値Ｖ２それぞれの値は、一例であり、特に限定されない。 The control unit 8 permits the supplying device 7 to supply the functional component to the airflow when the speed of the airflow blowing out from the outlet 24 is equal to or lower than the second threshold V2, which is larger than the first threshold V1, which is the threshold V1. FIG. 6 shows temporal changes in the speed of the airflow blowing out from the outlet 24 . In FIG. 6, the horizontal axis is time and the vertical axis is airflow velocity. The controller 8 changes the speed of the airflow, for example, within a range from a first speed VL to a second speed VH by controlling the fluctuation of the speed of the airflow. The second speed VH is greater than the first speed VL. The first speed VL is, for example, 0.05 m/sec. The second speed VH is, for example, 1.5 m/sec. The first threshold value V1 is determined so that the functional component reaches the target space on an air current, and is, for example, 1.0 m/sec. Also, the second threshold V2 is, for example, 1.6 m/sec. Each value of the first threshold V1 and the second threshold V2 is an example and is not particularly limited.
　また、制御部８は、機能成分を供給した時点ｔ１から所定時間Ｔ１が経過した時点ｔ２よりも後に気流の速度が第１閾値Ｖ１よりも大きく第２閾値Ｖ２以下となる時点ｔ３で供給装置７から気流へ機能成分を供給させる。制御部８は、時点ｔ１から所定時間Ｔ１が経過していない時点で気流の速度が第１閾値Ｖ１よりも大きく第２閾値Ｖ２以下となっても、供給装置７から気流へ機能成分を供給させない。所定時間Ｔ１は、例えば、３０秒であるが、３０秒に限定されない。 Further, the controller 8 controls the supply device 7 at time t3 when the airflow velocity becomes greater than the first threshold value V1 and equal to or less than the second threshold value V2 after time t2 when a predetermined time T1 has elapsed from time t1 when the functional component was supplied. supply functional ingredients to the air stream. The control unit 8 does not supply the functional component from the supply device 7 to the airflow even if the speed of the airflow is greater than the first threshold value V1 and equal to or less than the second threshold value V2 when the predetermined time T1 has not elapsed from the time point t1. . The predetermined time T1 is, for example, 30 seconds, but is not limited to 30 seconds.

Allow For example, when the driving voltage of the motor 36 is greater than the voltage value corresponding to the threshold value V1 and the driving voltage of the motor 36 is equal to or less than the voltage value corresponding to the second threshold value V2, the control method is such that from the supply device 7 to the airflow Allow to supply functional ingredients. As a result, the control method according to the first embodiment can suppress the amount of functional material used in the supply device 7, for example. Therefore, in the control method according to the first embodiment, for example, it is possible to reduce the frequency of exchanging the container containing the functional material in the generating unit 71 of the supply device 7 or the frequency of replenishing the container with the functional material. .
