　（実施の形態）
　［概要］
　まず、実施の形態に係る気流形成システムの概要について説明する。図１は、実施の形態に係る気流形成システムの概要を説明するための図である。図２は、実施の形態における送風装置の構成を説明するための図である。 (Embodiment)
[overview]
First, an overview of the airflow forming system according to the embodiment will be explained. FIG. 1 is a diagram for explaining an overview of an airflow forming system according to an embodiment. FIG. 2 is a diagram for explaining the configuration of the air blower in the embodiment.
　実施の形態に係る気流形成システムは、部屋８０に設置された送風装置１００によって実現される気流発生システムである。従来、部屋８０などの壁及び天井で囲まれた閉空間では、下方空間８５から上方空間８３への空気の還流が滞りやすくなり、安定したダウンフローを提供することが難しい。そのため、本実施の形態に係る気流発生システムでは、部屋８０などの閉空間において、部屋８０内の空気が下方空間から上方空間へ還流しやすくなるように、空気が還流する経路を確保する。 The airflow generation system according to the embodiment is an airflow generation system realized by a blower device 100 installed in a room 80. Conventionally, in a closed space such as the room 80 surrounded by walls and a ceiling, the return flow of air from the lower space 85 to the upper space 83 tends to become stagnant, making it difficult to provide a stable downflow. Therefore, in the airflow generation system according to the present embodiment, in a closed space such as the room 80, a path for air circulation is secured so that the air in the room 80 can easily circulate from the lower space to the upper space.
　送風装置１００は、天井８１と離間して並列に配置された複数のダクト１０と、複数のダクト１０のそれぞれの内部へ送風を行う第一送風機２０とを備える。複数のダクト１０は、それぞれ、天井８１と反対側にダクト１０の長手方向に沿う長尺状の吹き出し口１１を備えている。例えば、図２に示されるように、複数のダクト１０のそれぞれの吹き出し口１１は、第一送風機２０によって送風された空気を吹き出す。これにより、例えば、図２のＩＩ－ＩＩ断面線で切断された断面図に示されるように、複数のダクト１０と天井８１との間の上方空間８３に存在する空気が複数のダクト１０の間のそれぞれの空間に誘引され、複数のダクト１０の下方の空間（言い換えると、下方空間８５）へと向かう誘引気流（図中の白抜き矢印）が発生する。この空間を誘引空間８４と呼ぶ。送風装置１００は、複数のダクト１０のそれぞれの吹き出し口１１から空気を吹き出すことにより、吹き出された空気（吹出気流）と誘引気流とで形成される面空気（ダウンフローという）を発生させる。 The air blower 100 includes a plurality of ducts 10 arranged in parallel and spaced apart from the ceiling 81, and a first air blower 20 that blows air into each of the plurality of ducts 10. Each of the plurality of ducts 10 is provided with an elongated air outlet 11 along the longitudinal direction of the duct 10 on the side opposite to the ceiling 81. For example, as shown in FIG. 2, each air outlet 11 of the plurality of ducts 10 blows out air blown by the first blower 20. As a result, for example, as shown in the cross-sectional view taken along the II-II cross-sectional line in FIG. Attracted air currents (white arrows in the figure) are generated that are attracted to the respective spaces and move toward the spaces below the plurality of ducts 10 (in other words, the lower spaces 85). This space is called an attraction space 84. The blower device 100 blows air out of the air outlet 11 of each of the plurality of ducts 10, thereby generating surface air (referred to as downflow) formed by the blown air (blowout airflow) and the induced airflow.
　なお、誘引空間８４は、周囲に比べて気圧が低い状態（陰圧状態）であるため、気圧が低い状態を解消しようとする力が働く。その結果、複数のダクト１０の周囲の空気（ここでは、上方空間８３に存在する空気）が誘引空間８４に引き寄せられる（誘引されるともいう）。誘引空間８４が陰圧状態になるのは、複数のダクト１０に設けられた吹き出し口１１から空気が吹き出されることにより、吹き出された空気（吹出気流）の周囲の空間の空気が吹出気流に引き寄せられるためである。第一送風機２０の具体的な構成については、後述する。 Note that, since the attraction space 84 is in a state where the atmospheric pressure is lower than the surroundings (negative pressure state), a force acts to eliminate the low atmospheric pressure state. As a result, the air around the plurality of ducts 10 (here, the air existing in the upper space 83) is attracted (also referred to as being attracted) to the attraction space 84. The reason why the induced space 84 becomes a negative pressure state is because air is blown out from the air outlets 11 provided in the plurality of ducts 10, and the air in the space around the blown air (airflow) is turned into the airflow. This is because you are drawn to it. The specific configuration of the first blower 20 will be described later.
　以上により、本実施の形態に係る気流発生システムは、壁８２と天井８１とで囲まれた部屋８０のような閉空間において、部屋８０内の空気が下方空間８５から上方空間８３へ還流されやすいように空気が還流する経路を確保することで、部屋８０に設置された送風装置１００に安定したダウンフローを発生させることが可能となる。 As described above, in the airflow generation system according to the present embodiment, in a closed space such as the room 80 surrounded by the wall 82 and the ceiling 81, the air in the room 80 is easily returned from the lower space 85 to the upper space 83. By securing a path for the air to circulate in this way, it becomes possible to generate a stable downflow in the blower device 100 installed in the room 80.
　［構成］
　続いて、送風装置１００によって実現される気流発生システムの構成について図１及び図２を参照しながら説明する。 [composition]
Next, the configuration of the airflow generation system realized by the air blower 100 will be described with reference to FIGS. 1 and 2.
　送風装置１００は、複数のダクト１０と、第一送風機２０とを備える。 The blower device 100 includes a plurality of ducts 10 and a first blower 20.
　複数のダクト１０のそれぞれは、Ｙ軸方向を長手方向とする長尺状である。複数のダクト１０は、Ｙ軸方向と交差するＸ軸方向に並んで配置される。つまり、複数のダクト１０は、並列に配置される。複数のダクト１０の間には、隙間が設けられている。複数のダクト１０は、１つのＸＹ平面上に配置されている。 Each of the plurality of ducts 10 has an elongated shape whose longitudinal direction is in the Y-axis direction. The plurality of ducts 10 are arranged in parallel in the X-axis direction that intersects the Y-axis direction. That is, the plurality of ducts 10 are arranged in parallel. A gap is provided between the plurality of ducts 10. The plurality of ducts 10 are arranged on one XY plane.
　ダクト１０は、より具体的には、中空の直方体状である。ダクト１０の上面（Ｚ軸マイナス側の面）及び２つの側面（Ｘ軸プラス側及びマイナス側の面）は、閉鎖されている。つまり、ダクト１０の上面及び２つの側面には、開口が設けられていない。ダクト１０は、例えば、樹脂材料によって形成されるが、アルミニウムなどの軽量の金属材料によって形成されてもよい。 More specifically, the duct 10 has a hollow rectangular parallelepiped shape. The top surface (Z-axis negative side surface) and two side surfaces (X-axis positive side and negative side) of the duct 10 are closed. That is, no opening is provided on the top surface and two side surfaces of the duct 10. The duct 10 is made of, for example, a resin material, but may also be made of a lightweight metal material such as aluminum.
　ダクト１０の下面（Ｚ軸プラス側の面）には、吹き出し口１１が設けられている。吹き出し口１１は、ダクト１０の長手方向（Ｙ軸方向）に沿う長尺状の開口であって、第一送風機２０がダクト１０の内部に送風を行うと、吹き出し口１１からは、下方（Ｚ軸プラス方向）へ空気が吹き出される。吹き出し口１１は、例えば、図２のＩＩ－ＩＩ断面線で示される断面図のように、吹き出し口１１の幅（Ｘ軸方向の長さ）は、下方へ向かうほど狭くなる。吹き出し口１１の幅は、例えば、下方へ向かうほど指数関数的に狭くなる。 An air outlet 11 is provided on the lower surface (Z-axis positive side surface) of the duct 10. The air outlet 11 is an elongated opening along the longitudinal direction (Y-axis direction) of the duct 10, and when the first blower 20 blows air into the duct 10, the air outlet 11 opens downward (Z-axis direction). Air is blown out in the positive direction of the shaft. The width (length in the X-axis direction) of the air outlet 11 becomes narrower as it goes downward, as shown in the cross-sectional view taken along the line II-II in FIG. 2, for example. For example, the width of the air outlet 11 becomes exponentially narrower as it goes downward.
　ダクト１０は、正面（Ｙ軸プラス側）には開口が設けられていないが、背面（Ｙ軸マイナス側）に第一送風機２０から送風される空気がダクト１０の内部へ送風される通気口（図１、図２で不図示）が設けられている。通気口は、第一送風機２０の筐体内部につながっており、第一送風機２０は通気口を介して複数のダクト１０のそれぞれの内部に送風を行う。第一送風機２０の送風による空気の流れは、図２の破線矢印で示されている。 The duct 10 is not provided with an opening on the front (Y-axis positive side), but has a ventilation hole ( (not shown in FIGS. 1 and 2) is provided. The vent is connected to the inside of the casing of the first blower 20, and the first blower 20 blows air into each of the plurality of ducts 10 through the vent. The flow of air caused by the first blower 20 is indicated by the dashed arrow in FIG. 2 .
　続いて、第一送風機２０について説明する。第一送風機２０は、複数のダクト１０の長手方向の一方の端部（Ｙ軸マイナス側の端部）に位置し、複数のダクト１０のそれぞれの内部へ送風を行う。第一送風機２０は、例えば、部屋８０の壁８２の内部空間に設置される。第一送風機２０は、壁８２の下部に設けられた開口から、送風装置１００によって下方空間８５に吹き出された空気を吸引し、上方へ向けて送出する。第一送風機２０は、ファン２１と、配管２２と、フィルタユニット２３とを備える。ファン２１は、高圧空気を発生させるための羽車（不図示）と羽車を駆動するモータ（不図示）とを含む。フィルタユニット２３には、例えばＨＥＰＡ（Ｈｉｇｈ　Ｅｆｆｉｃｉｅｎｃｙ　Ｐａｒｔｉｃｕｌａｔｅ　Ａｉｒ）フィルタが内設されている。フィルタユニット２３の正面（Ｙ軸プラス側の面）は、複数のダクト１０のそれぞれの背面側の通気口（不図示）と連通する送風口（不図示）が設けられる。フィルタユニット２３の下方（Ｚ軸プラス側）に開口（不図示）が設けられており、配管２２と連結されている。フィルタユニット２３の筐体は、例えば、樹脂材料によって形成されるが、アルミニウムなどの軽量の金属材料によって形成されてもよい。なお、ファン２１の配置は一例である。ファン２１は、複数のダクト１０のそれぞれの内部へ空気を送り込むことができるのであれば、どのように配置されてもよい。 Next, the first blower 20 will be explained. The first blower 20 is located at one end of the plurality of ducts 10 in the longitudinal direction (the end on the negative side of the Y-axis), and blows air into the inside of each of the plurality of ducts 10. The first blower 20 is installed, for example, in the interior space of the wall 82 of the room 80. The first blower 20 sucks air blown into the lower space 85 by the blower 100 from an opening provided in the lower part of the wall 82, and sends it upward. The first blower 20 includes a fan 21, piping 22, and a filter unit 23. The fan 21 includes an impeller (not shown) for generating high-pressure air and a motor (not shown) that drives the impeller. The filter unit 23 includes, for example, a HEPA (High Efficiency Particulate Air) filter. The front surface (Y-axis positive side surface) of the filter unit 23 is provided with an air outlet (not shown) that communicates with the air vents (not shown) on the back side of each of the plurality of ducts 10 . An opening (not shown) is provided below the filter unit 23 (on the Z-axis positive side) and is connected to the pipe 22. The housing of the filter unit 23 is made of, for example, a resin material, but may also be made of a lightweight metal material such as aluminum. Note that the arrangement of the fan 21 is an example. The fan 21 may be arranged in any manner as long as it can send air into each of the plurality of ducts 10.
　以上説明したように、送風装置１００は、第一送風機２０の送風によって送風された空気が複数のダクト１０のそれぞれの長手方向に沿う吹き出し口１１から吹き出されると、複数のダクト１０のうち隣り合う２つのダクト１０の間のそれぞれの空間（いわゆる、誘引空間８４）に、複数のダクト１０の上方空間８３の空気が引き寄せられる（言い換えると、誘引される）。これにより、複数のダクト１０のうち隣り合う２つのダクト１０の間のそれぞれの誘引空間８４から下方空間８５へ向かう誘引気流（図２の白拭き矢印）が発生するため、送風装置１００は、複数のダクト１０の吹き出し口１１から下方空間８５へ向かって吹き出される吹出気流と、当該複数のダクト１０の間の誘引空間８４から下方空間８５へ向かう誘引気流とで形成されるダウンフローを発生することができる。 As described above, when the air blown by the first blower 20 is blown out from the outlet 11 along the longitudinal direction of each of the plurality of ducts 10, the air blower 100 is configured to The air in the space 83 above the plurality of ducts 10 is drawn (in other words, attracted) to each space (so-called attraction space 84) between two matching ducts 10. As a result, an induced airflow (indicated by the white wiping arrow in FIG. 2) from each of the induced spaces 84 between two adjacent ducts 10 of the plurality of ducts 10 toward the lower space 85 is generated. A downflow is generated by a blowout airflow blown out from the outlet 11 of the duct 10 toward the lower space 85 and an induced airflow directed from the attraction space 84 between the plurality of ducts 10 toward the lower space 85. be able to.
　続いて、部屋８０に形成される領域について説明する。 Next, the area formed in the room 80 will be explained.
　部屋８０には、複数のダクト１０が並列に配置される仮想面９０（図４参照）において、下方空間８５から上方空間８３へ還流する空気が通過する還流通過領域９１が形成される。 In the room 80, a reflux passage area 91 through which air flowing back from the lower space 85 to the upper space 83 passes is formed in a virtual plane 90 (see FIG. 4) where a plurality of ducts 10 are arranged in parallel.
　部屋８０内の空気が下方空間８５から上方空間８３へ還流されやすいように空気が還流する経路を確保するためには、天井８１から見た部屋８０の上面視において、誘引空間８４の面積の合計が還流通過領域９１の面積の合計よりも小さいとよい。上面視における誘引空間８４の面積は、誘引空間８４の仮想面９０上の領域（以下、誘引領域という）の面積である。 In order to secure an air circulation path so that the air in the room 80 is easily returned from the lower space 85 to the upper space 83, the total area of the attraction space 84 must be is preferably smaller than the total area of the reflux passage region 91. The area of the attraction space 84 when viewed from above is the area of the area on the virtual plane 90 of the attraction space 84 (hereinafter referred to as attraction area).
　以下、第１例～第３例を挙げて、これらの領域についてより具体的に説明する。 Hereinafter, these areas will be explained in more detail using the first to third examples.
　［第１例］
　第１例では、全てのダクト１０の吹き出し口１１から空気が吹き出されている場合に形成される領域ついて説明する。図３は、実施の形態に係る気流形成システムにおいて部屋８０内に形成される領域の第１例を示す図である。図４は、図３に示される気流形成システムにおける空気の還流を模式的に示す図である。 [First example]
In the first example, a region formed when air is blown out from the air outlets 11 of all the ducts 10 will be described. FIG. 3 is a diagram showing a first example of a region formed within the room 80 in the airflow forming system according to the embodiment. FIG. 4 is a diagram schematically showing air recirculation in the airflow forming system shown in FIG. 3. FIG.
　図３に示されるように、第１例では、誘引空間８４は、部屋８０に設置された４つのダクト１０のうち隣り合う２つのダクト１０の間の空間であり、部屋８０には３つの誘引空間８４が形成される。このとき、部屋８０には、２つの還流通過領域９１が形成される。具体的には、２つの還流通過領域９１は、４つのダクト１０のうち壁８２と直接対向する２つのダクト１０のそれぞれについて、仮想面９０上で当該ダクト１０と壁８２との間に形成される領域である。ここで、壁８２と直接対向するダクト１０とは、一方側に対となるダクト１０が存在し、他方側に対となるダクト１０が存在せず、かつ、壁８２が存在するダクト１０である。 As shown in FIG. 3, in the first example, the attraction space 84 is a space between two adjacent ducts 10 among the four ducts 10 installed in the room 80; A space 84 is formed. At this time, two reflux passage areas 91 are formed in the chamber 80. Specifically, two reflux passage areas 91 are formed between the duct 10 and the wall 82 on the virtual plane 90 for each of the two ducts 10 that directly oppose the wall 82 among the four ducts 10. This is an area where Here, the duct 10 that directly faces the wall 82 is a duct 10 that has a paired duct 10 on one side, does not have a paired duct 10 on the other side, and has the wall 82. .
　第１例では、図４において矢印で示されるように、下方空間８５の空気は、壁８２と直接対向するダクト１０と、壁８２との間の空間を通って上方空間８３へ還流する。当該空間の仮想面９０上の領域が還流通過領域９１である。 In the first example, as shown by the arrow in FIG. 4, the air in the lower space 85 flows back into the upper space 83 through the space between the wall 82 and the duct 10 that directly faces the wall 82. A region on the virtual plane 90 of the space is a reflux passage region 91.
　第１例では、天井８１から見た部屋８０の上面視において、誘引空間８４の面積の合計が還流通過領域９１の面積の合計よりも小さくなるように、隣り合うダクト１０同士の距離（言い換えると、配置間隔）よりも、４つのダクト１０の並び方向において最も壁８２側に配置されたダクト１０と壁８２との距離を大きくするとよい。 In the first example, in a top view of the room 80 from the ceiling 81, the distance between adjacent ducts 10 (in other words, , arrangement interval), the distance between the duct 10 placed closest to the wall 82 in the direction in which the four ducts 10 are lined up and the wall 82 may be made larger.
　［第１例の変形例］
　図４では、図３に示される２つの還流通過領域９１のうち一方の（Ｘ軸プラス側の）還流通過領域９１について、当該還流通過領域９１を通過した還流空気が複数のダクト１０の上方空間８３へ流入する流入面９２を示している。例えば、第１例の変形例では、流入面９２の縦幅Ｈ２は、還流通過領域９１の横幅Ｗ１以上であってもよい。これにより、下方空間８５の空気が複数のダクト１０と天井８１との間の上方空間８３へ流入するときの抵抗を軽減することができるため、空気が還流しやすくなる。このとき、還流通過領域９１の面積Ｓ１と流入面９２の面積Ｓ２との関係は、特に限定されないが、Ｓ２≧Ｓ１であってもよい。 [Modification of the first example]
In FIG. 4, for one of the two reflux passage areas 91 (on the positive side of the X axis) shown in FIG. An inflow surface 92 into 83 is shown. For example, in a modification of the first example, the vertical width H2 of the inflow surface 92 may be equal to or greater than the horizontal width W1 of the reflux passage area 91. This can reduce resistance when air in the lower space 85 flows into the upper space 83 between the plurality of ducts 10 and the ceiling 81, making it easier for the air to circulate. At this time, the relationship between the area S 1 of the reflux passage region 91 and the area S 2 of the inflow surface 92 is not particularly limited, but may be S 2 ≧S 1 .
　［第２例］
　第１例では、全てのダクト１０の吹き出し口１１から空気が吹き出される場合に形成される領域について説明した。第２例では、複数のダクト１０のうち隣り合うダクト１０の一方のダクト１０の吹き出し口１１が閉じられている場合の一例として、壁８２とそれぞれ直接対向する２つのダクト１０のどちらかのダクト１０の吹き出し口１１が閉じられている場合に形成される領域について説明する。図５は、実施の形態に係る気流形成システムにおいて部屋８０内に形成される領域の第２例を示す図である。 [Second example]
In the first example, the region formed when air is blown out from the air outlets 11 of all the ducts 10 has been described. In the second example, as an example of a case where the outlet 11 of one of the ducts 10 adjacent to each other among the plurality of ducts 10 is closed, one of the two ducts 10 directly facing the wall 82 The area formed when the 10 air outlets 11 are closed will be described. FIG. 5 is a diagram showing a second example of a region formed within the room 80 in the airflow forming system according to the embodiment.
　図５に示されるように、第２例では、壁８２とそれぞれ直接対向する２つのダクト１０のうち紙面の右端に位置するダクト１０の吹き出し口１１が閉じられている（言い換えると、閉じられた部分１２を有する）場合、当該ダクト１０（紙面の右端のダクト１０）と、その隣に配置されたダクト１０（紙面の右端から２つめのダクト１０）との間の空間も空気が還流する経路に含まれる。このように、複数のダクト１０のうち隣り合うダクト１０の一方のダクト１０の吹き出し口１１が閉じられている場合、当該隣り合うダクト１０の間の空間の仮想面９０上の領域も還流通過領域９１に含まれる。第２例では、３つの還流通過領域９１と２つの誘引空間８４とが形成される。なお、図１、図２に示されていないが、吹き出し口１１は、吹き出し口１１に沿う複数のルーバを備えてもよい。複数のルーバが吹き出し口１１を覆うことで吹き出し口１１の一部又は全部が閉じられてもよい。 As shown in FIG. 5, in the second example, the air outlet 11 of the duct 10 located at the right end of the paper of the two ducts 10 directly facing the wall 82 is closed (in other words, the air outlet 11 is closed). 12), the space between the duct 10 (the duct 10 at the right end in the paper) and the duct 10 placed next to it (the second duct 10 from the right end in the paper) is also a path for air to return. include. In this way, when the outlet 11 of one of the adjacent ducts 10 among the plurality of ducts 10 is closed, the area on the virtual plane 90 of the space between the adjacent ducts 10 is also a reflux passage area. Included in 91. In the second example, three reflux passage areas 91 and two attraction spaces 84 are formed. Although not shown in FIGS. 1 and 2, the air outlet 11 may include a plurality of louvers along the air outlet 11. A part or all of the air outlet 11 may be closed by covering the air outlet 11 with a plurality of louvers.
　第２例では、部屋８０には、３つの還流通過領域９１と２つの誘引空間８４とが形成されるため、天井８１から見た部屋８０の上面視において、誘引空間８４の面積の合計が還流通過領域９１の面積の合計よりも小さくなる。 In the second example, three reflux passage areas 91 and two attraction spaces 84 are formed in the room 80, so that when viewed from the top of the room 80 from the ceiling 81, the total area of the attraction spaces 84 is It is smaller than the total area of the passage area 91.
　なお、第２例では、複数のダクト１０のうち隣り合うダクト１０の一方のダクト１０の吹き出し口１１が閉じられている場合の一例として、壁８２とそれぞれ直接対向する２つのダクト１０のどちらかのダクト１０の吹き出し口１１が閉じられている例を示したが、これに限られない。例えば、両隣に他のダクト１０が配置されているダクト１０（図５の４つのダクト１０のうち真ん中の２つのダクト）のうちの１つのダクト１０の吹き出し口１１が閉じられてもよい。この場合、当該ダクト１０の両側に位置する他のダクト１０との間の空間も空気が還流する経路に含まれるため、部屋８０には、４つの還流通過領域９１と１つの誘引空間８４とが形成される。このように、４つのダクト１０のいずれか１つのダクト１０の吹き出し口１１を閉じると、天井８１から見た部屋８０の上面視において、誘引空間８４の面積の合計が還流通過領域９１の面積の合計よりも小さくなる。 In addition, in the second example, as an example of a case where the air outlet 11 of one of the adjacent ducts 10 among the plurality of ducts 10 is closed, either of the two ducts 10 directly facing the wall 82 Although the example is shown in which the outlet 11 of the duct 10 is closed, the present invention is not limited to this. For example, the air outlet 11 of one of the ducts 10 (the middle two ducts of the four ducts 10 in FIG. 5) that have other ducts 10 arranged on both sides thereof may be closed. In this case, the space between the duct 10 and other ducts 10 located on both sides is also included in the air return path, so the room 80 has four return flow passage areas 91 and one attraction space 84. It is formed. In this way, when the air outlet 11 of any one of the four ducts 10 is closed, the total area of the attraction space 84 is equal to the area of the reflux passage area 91 in the top view of the room 80 seen from the ceiling 81. less than the sum.
　［第３例］
　第２例では、複数のダクト１０のうち隣り合うダクト１０の一方のダクト１０の吹き出し口１１が閉じられている場合の一例として、部屋８０に設置された４つのダクト１０のうちの１つのダクト１０の吹き出し口１１を閉じた場合に形成される領域について説明した。第３例では、複数のダクト１０のうち隣り合うダクト１０の少なくとも一方のダクト１０の吹き出し口１１の一部が閉じられている場合の一例として、壁８２とそれぞれ直接対向する２つのダクト１０のどちらかのダクト１０の吹き出し口１１の一部が閉じられている場合に形成される領域について説明する。図６は、実施の形態に係る気流形成システムにおいて部屋８０内に形成される領域の第３例を示す図である。図７は、図６に示される気流形成システムにおける空気の還流を模式的に示す図である。 [Third example]
In the second example, as an example of a case where the air outlet 11 of one of the ducts 10 adjacent to each other among the plurality of ducts 10 is closed, one of the four ducts 10 installed in the room 80 The area formed when the 10 air outlets 11 are closed has been described. In the third example, as an example of a case where a part of the air outlet 11 of at least one of the adjacent ducts 10 among the plurality of ducts 10 is closed, two ducts 10 each directly facing the wall 82 are A region formed when a part of the air outlet 11 of either duct 10 is closed will be described. FIG. 6 is a diagram showing a third example of a region formed within the room 80 in the airflow forming system according to the embodiment. FIG. 7 is a diagram schematically showing air recirculation in the airflow forming system shown in FIG. 6.
　図６に示されるように、第３例では、壁８２とそれぞれ直接対向する２つのダクト１０のうち紙面の右端に位置するダクト１０の吹き出し口１１の一部が閉じられている（言い換えると、吹き出し口１１の一部に閉じられた部分１２を有する）場合、当該ダクト１０（紙面の右端のダクト１０）と、その隣に配置されたダクト１０（紙面の右端から２つめのダクト１０）との間の空間のうち、閉じられた部分１２に対応する空間も空気が還流する経路に含まれる。このように、複数のダクト１０のうち隣り合うダクト１０の一方のダクト１０の吹き出し口１１の一部が閉じられている場合、当該隣り合うダクト１０の間の空間のうち吹き出し口１１が閉じられた部分１２に対応する空間の仮想面９０上の領域も還流通過領域９１に含まれる。 As shown in FIG. 6, in the third example, of the two ducts 10 directly facing the wall 82, the outlet 11 of the duct 10 located at the right end of the paper is partially closed (in other words, When the air outlet 11 has a closed part 12), the duct 10 (the duct 10 on the right end of the paper) and the duct 10 placed next to it (the second duct 10 from the right end of the paper) Among the spaces between them, the space corresponding to the closed portion 12 is also included in the air circulation path. In this way, when a part of the air outlet 11 of one of the adjacent ducts 10 among the plurality of ducts 10 is closed, the air outlet 11 in the space between the adjacent ducts 10 is closed. The area on the virtual plane 90 of the space corresponding to the portion 12 is also included in the reflux passage area 91.
　図７の（ａ）は、図６に示される空間Ａの還流通過領域９１を通過する還流空気が複数のダクト１０の誘引空間８４上の上方空間８３へ流入する例を模式的に示す図である。第３例では、図７の（ａ）において矢印で示されるように、下方空間８５の空気は、壁８２と直接対向するダクト１０と壁８２との間の空間のうち図６の空間Ａを通って上方空間８３へ還流する。 FIG. 7A is a diagram schematically showing an example in which the recirculation air passing through the recirculation passage area 91 of the space A shown in FIG. 6 flows into the upper space 83 above the attraction spaces 84 of the plurality of ducts 10. be. In the third example, as shown by the arrow in FIG. 7(a), the air in the lower space 85 flows through the space A in FIG. The water flows through the air and flows back into the upper space 83.
　また、図７の（ｂ）は、図６に示される空間Ｂの還流通過領域９１を通過する還流空気が還流通過領域９１と隣接する複数のダクト１０の上方空間８３へ流入する例を模式的に示す図である。第３例では、図７の（ｂ）において矢印で示されるように、下方空間８５の空気は、吹き出し口１１の一部が閉じられたダクト１０両側の空間であって、吹き出し口１１が閉じられた部分１２に対応する２つの空間（図６の空間Ｂ）を通って上方空間８３へ還流する。なお、図７の（ｂ）では、図６の紙面右端の１つのダクト１０のみ記載している。 7B schematically shows an example in which the recirculation air passing through the recirculation passage area 91 of the space B shown in FIG. 6 flows into the space 83 above the plurality of ducts 10 adjacent to the recirculation passage area 91. FIG. In the third example, as shown by the arrow in FIG. 7(b), the air in the lower space 85 is a space on both sides of the duct 10 where the outlet 11 is partially closed. It flows back to the upper space 83 through two spaces (space B in FIG. 6) corresponding to the separated portion 12. Note that, in FIG. 7(b), only one duct 10 at the right end of the paper in FIG. 6 is illustrated.
　第３例では、天井８１から見た部屋８０の上面視において、誘引空間８４の面積の合計が還流通過領域９１の面積の合計よりも小さくなるように、吹き出し口１１が閉じられる部分１２を増やしてもよいし、隣り合うダクト１０同士の距離（いわゆる配置間隔）よりも４つのダクト１０の並び方向において最も壁８２側に配置されたダクト１０と壁８２との距離を大きくしてもよい。 In the third example, the portion 12 where the air outlet 11 is closed is increased so that the total area of the attraction space 84 is smaller than the total area of the reflux passage area 91 in a top view of the room 80 seen from the ceiling 81. Alternatively, the distance between the duct 10 disposed closest to the wall 82 in the direction in which the four ducts 10 are arranged and the wall 82 may be greater than the distance between adjacent ducts 10 (so-called arrangement interval).
　［第３例の変形例］
　例えば、第３例の変形例では、流入面９２の縦幅Ｈ２１は、還流通過領域の横幅Ｗ１１以上であってもよい。これにより、下方空間８５の空気が複数のダクト１０と天井８１との間の上方空間８３へ流入するときの抵抗を軽減することができるため、空気が還流しやすくなる。このとき、還流通過領域９１の面積Ｓ１１と流入面９２の面積Ｓ２１との関係は、特に限定されないが、Ｓ２１≧Ｓ１１であってもよい。 [Variation of the third example]
For example, in a modification of the third example, the vertical width H21 of the inflow surface 92 may be equal to or greater than the horizontal width W11 of the reflux passage area. This can reduce resistance when air in the lower space 85 flows into the upper space 83 between the plurality of ducts 10 and the ceiling 81, making it easier for the air to circulate. At this time, the relationship between the area S 11 of the reflux passage region 91 and the area S 21 of the inflow surface 92 is not particularly limited, but may be S 21 ≧S 11 .
　また、第３例の変形例では、流入面９２の縦幅Ｈ２２は、還流通過領域の横幅Ｗ１２以上であってもよいし、図示されていないが、隣り合うダクト１０同士の距離（いわゆる、配置間隔）以上であってもよい。これにより、下方空間８５の空気が複数のダクト１０と天井８１との間の上方空間８３へ流入するときの抵抗を軽減することができるため、空気が還流しやすくなる。このとき、還流通過領域９１の面積Ｓ１２と流入面９２の面積Ｓ２２との関係は、特に限定されないが、Ｓ２２≧Ｓ１２であってもよい。 In a modification of the third example, the vertical width H 22 of the inflow surface 92 may be equal to or greater than the width W 12 of the return flow passage area, and although not shown, the distance between adjacent ducts 10 (so-called , arrangement interval) or more. This can reduce resistance when air in the lower space 85 flows into the upper space 83 between the plurality of ducts 10 and the ceiling 81, making it easier for the air to circulate. At this time, the relationship between the area S 12 of the reflux passage region 91 and the area S 22 of the inflow surface 92 is not particularly limited, but may be S 22 ≧S 12 .
　（変形例１）
　上記実施の形態において、送風装置１００は、複数のダクト１０が部屋８０の天井８１から離間して天井８１と平行な仮想面９０上に並列に設置され、複数のダクト１０の長手方向に沿う吹き出し口１１から下方に向けて空気を吹き出す例を説明したが、この例に限られない。例えば、送風装置１００は、複数のダクト１０が壁８２から離間して壁８２と平行な仮想面９０上に並列に配置され、複数のダクト１０の長手方向に沿う吹き出し口１１から部屋８０の側方（例えば、前後左右方向）に向けて空気を吹き出してもよい。このように、送風装置１００は、設置状態に応じて任意の方向に向けて吹き出し口１１から空気を吹き出すことにより、複数のダクト１０の間の空間に空気を誘引し、誘引された空気を吹き出し口１１から吹き出される空気と同じ任意の方向へ提供することができる。 (Modification 1)
In the embodiment described above, the blower device 100 has a plurality of ducts 10 spaced apart from the ceiling 81 of the room 80 and installed in parallel on a virtual plane 90 parallel to the ceiling 81, and blows air out along the longitudinal direction of the plurality of ducts 10. Although an example in which air is blown downward from the mouth 11 has been described, the present invention is not limited to this example. For example, in the blower device 100, a plurality of ducts 10 are spaced apart from a wall 82 and arranged in parallel on a virtual plane 90 parallel to the wall 82, and from the air outlet 11 along the longitudinal direction of the plurality of ducts 10 to the side of the room 80. Air may be blown out in a direction (for example, front, rear, left, and right directions). In this way, the blower device 100 attracts air into the space between the plurality of ducts 10 by blowing air out of the outlet 11 in an arbitrary direction depending on the installation state, and blows out the attracted air. It can be provided in the same arbitrary direction as the air blown out from the mouth 11.
　（変形例２）
　上記の実施の形態において、気流発生システムは、部屋８０に設置された送風装置１００によって実現され、部屋８０内の空気を自然還流により還流させる例を説明したが、この例に限られない。例えば、気流発生システムは、さらに、下方空間８５に設置され、かつ、下方空間８５から上方空間８３へ向けて送風を行う第二送風機（不図示）を備えてもよい。例えば、第二送風機は、床面から所定の高さに設置されたファンでもよいし、空気を吸引する吸引口とファンとフィルタとを備えるユニットであってもよい。 (Modification 2)
In the above embodiment, an example has been described in which the airflow generation system is realized by the blower device 100 installed in the room 80, and the air in the room 80 is recirculated by natural recirculation, but the system is not limited to this example. For example, the airflow generation system may further include a second blower (not shown) that is installed in the lower space 85 and blows air from the lower space 85 to the upper space 83. For example, the second blower may be a fan installed at a predetermined height from the floor surface, or may be a unit including a suction port for sucking air, a fan, and a filter.
　これにより、気流発生システムは、第二送風機の送風により部屋８０の下方空間８５から上方空間８３への空気の還流を促すことができるため、部屋８０などの閉空間において安定したダウンフローを提供することができる。 Thereby, the airflow generation system can promote the circulation of air from the lower space 85 of the room 80 to the upper space 83 by the air blowing from the second blower, thereby providing a stable downflow in a closed space such as the room 80. be able to.
　［効果等］
　以上説明したように、気流形成システムは、部屋８０に設置された送風装置１００によって実現される気流形成システムであって、送風装置１００は、天井８１から離間して並列に配置された長尺状の複数のダクト１０と、複数のダクト１０のそれぞれの内部へ送風を行う第一送風機２０と、を備え、複数のダクト１０のそれぞれには、天井８１と反対側に当該ダクト１０の長手方向に沿う長尺状の吹き出し口であって、送風により空気が吹き出される吹き出し口１１が設けられ、部屋８０には、複数のダクト１０が並列に配置される仮想面９０において、複数のダクト１０の下方空間８５から複数のダクト１０と天井８１との間の上方空間８３へ還流する空気が通過する還流通過領域９１が形成される。 [Effects etc.]
As explained above, the airflow forming system is an airflow forming system realized by the air blower 100 installed in the room 80, and the air blower 100 is a long airflow forming system that is spaced apart from the ceiling 81 and arranged in parallel. a plurality of ducts 10 , and a first blower 20 that blows air into the inside of each of the plurality of ducts 10 , and each of the plurality of ducts 10 includes a plurality of ducts 10 on the side opposite to the ceiling 81 in the longitudinal direction of the duct 10 . In the room 80, a plurality of ducts 10 are arranged in a virtual plane 90 in which a plurality of ducts 10 are arranged in parallel. A recirculation passage region 91 is formed through which air flowing back from the lower space 85 to the upper space 83 between the plurality of ducts 10 and the ceiling 81 passes.
　このような気流形成システムは、部屋８０などの閉鎖空間において、複数のダクト１０の上方空間８３へ空気を還流させることができるため、安定したダウンフロー気流を提供することができる。 Such an airflow forming system can return air to the space 83 above the plurality of ducts 10 in a closed space such as the room 80, and therefore can provide a stable downflow airflow.
　また、例えば、還流通過領域９１は、複数のダクト１０のうち隣り合う２つのダクト１０の少なくとも一方のダクト１０の吹き出し口１１の一部１２が閉じられている場合、隣り合う２つのダクト１０の間の空間のうち一部１２の吹き出し口１１に対応する空間の仮想面９０上の領域を含む。 Further, for example, when a part 12 of the outlet 11 of at least one of the two adjacent ducts 10 among the plurality of ducts 10 is closed, the reflux passage area 91 is It includes a region on the virtual surface 90 of the space corresponding to the air outlet 11 of part 12 of the space between.
　このような気流形成システムは、複数のダクト１０のうち隣り合う２つのダクト１０の少なくとも一方のダクト１０の吹き出し口１１の一部１２を閉じることで、隣り合う２つのダクト１０の間に還流通過領域９１を形成することができる。そのため、気流形成システムは、必要に応じて、複数のダクト１０の上方空間８３への空気の還流を調整することができる。 Such an airflow forming system allows return flow to pass between two adjacent ducts 10 by closing a part 12 of the outlet 11 of at least one of the two adjacent ducts 10 among the plurality of ducts 10. Region 91 can be formed. Therefore, the airflow forming system can adjust the return of air to the upper space 83 of the plurality of ducts 10 as necessary.
　また、例えば、天井８１から見た部屋８０の上面視において、複数のダクト１０の間の空間であって、上方空間８３から空気が引き寄せられる誘引空間８４の面積の合計は、還流通過領域９１の面積の合計よりも小さい。 Further, for example, in a top view of the room 80 from the ceiling 81, the total area of the attraction space 84, which is a space between the plurality of ducts 10 and from which air is drawn from the upper space 83, is equal to the total area of the reflux passage area 91. less than the sum of the areas.
　このような気流発生システムは、部屋８０内の空気をより多く上方空間８３へ還流させることができる。そのため、気流発生システムは、安定したダウンフロー気流を提供することができる。 Such an airflow generation system can circulate more of the air in the room 80 to the upper space 83. Therefore, the airflow generation system can provide a stable downflow airflow.
　また、例えば、還流通過領域９１を通過した空気が複数のダクト１０のそれぞれの上方空間８３に流入する流入面９２の面積の合計は、天井８１から見た部屋８０の上面視における還流通過領域９１の面積の合計以上である。 Further, for example, the total area of the inflow surface 92 through which the air that has passed through the reflux passage area 91 flows into the upper space 83 of each of the plurality of ducts 10 is the sum of the area of the reflux passage area 91 in the top view of the room 80 seen from the ceiling 81. is greater than or equal to the sum of the areas of
　このような気流発生システムは、下方空間８５の空気が複数のダクト１０と天井８１との間の上方空間８３へ流入するときの抵抗を軽減することができるため、部屋８０内の空気をより多く上方空間８３へ還流させることができる。そのため、気流発生システムは、安定したダウンフロー気流を提供することができる。 Such an airflow generation system can reduce the resistance when the air in the lower space 85 flows into the upper space 83 between the plurality of ducts 10 and the ceiling 81, so it can increase the amount of air in the room 80. It can be refluxed to the upper space 83. Therefore, the airflow generation system can provide a stable downflow airflow.
　また、例えば、気流形成システムは、さらに、下方空間８５に設置され、かつ、下方空間８５から上方空間８３へ向けて送風を行う第二送風機（不図示）を備える。 For example, the airflow forming system further includes a second blower (not shown) that is installed in the lower space 85 and blows air from the lower space 85 to the upper space 83.
　このような気流発生システムは、第二送風機により部屋８０内の空気を下方空間８５から上方空間８３へ還流させることができる。そのため、気流発生システムは、安定したダウンフロー気流を提供することができる。 Such an airflow generation system can circulate the air in the room 80 from the lower space 85 to the upper space 83 using the second blower. Therefore, the airflow generation system can provide a stable downflow airflow.
