The control unit (93) is provided in the air handling unit (2).
　　－運転動作－
　　　〈通常運転動作〉
　次に、空気調和システム（1）の通常の運転動作について説明する。 -Driving operation-
<Normal operation operation>
Next, the normal operation operation of the air conditioning system (1) will be described.
　エアハンドリングユニット（2）のファン（25）が駆動すると、空気通路（P）に空気の流れが生じる。空気通路（P）に空気の流れが生じると、集塵ユニット（3）の吸込口（31）から室外空気（OA）が吸い込まれる（図２における黒矢印を参照）。吸い込まれた空気は、フィルタユニット（40）の下側へ流入し、フィルタユニット（40）を通過して、第１流出口（32）へ流れる。 When the fan (25) of the air handling unit (2) is driven, an air flow is generated in the air passage (P). When an air flow occurs in the air passage (P), outdoor air (OA) is sucked in from the suction port (31) of the dust collecting unit (3) (see the black arrow in FIG. 2). The sucked air flows into the lower side of the filter unit (40), passes through the filter unit (40), and flows to the first outlet (32).
　具体的には、第１吸込口（31a）及び第２吸込口（31b）から吸い込まれた室外空気（OA）は、フィルタユニット（40）に向かって流れる。この空気は、フィルタ（41）の各平面部（41a）、各側面部（41b）、及び連続部（41c）を通過する。室外空気（OA）がフィルタ（41）を通過する際に、室外空気（OA）に含まれる被捕集物がフィルタ（41）に捕集されて、被捕集物と清浄化された空気とに分離される。フィルタ（41）を通過して清浄化された空気は、フィルタ（41）の内部空間を上方に流れ、保持部材（42）の貫通孔（43）から第２ケーシング（30）の上方空間に流出する。第２ケーシング（30）の上方空間に流出した空気は、第１流出口（32）を通過して、第１ダクト（4）に流入する。 Specifically, the outdoor air (OA) sucked from the first suction port (31a) and the second suction port (31b) flows toward the filter unit (40). This air passes through each flat portion (41a), each side portion (41b), and continuous portion (41c) of the filter (41). When the outdoor air (OA) passes through the filter (41), the collected material contained in the outdoor air (OA) is collected by the filter (41), and the collected material and the purified air are combined. Is separated into. The purified air that has passed through the filter (41) flows upward through the internal space of the filter (41) and flows out from the through hole (43) of the holding member (42) to the space above the second casing (30). do. The air flowing out to the space above the second casing (30) passes through the first outlet (32) and flows into the first duct (4).
　第１ダクト（4）を通過した空気は、エアハンドリングユニット（2）の第２流入口（21）から流入し、熱交換器（24）を通過する。空気が熱交換器（24）を通過する際に、その空気の温度が調節される。温度調節された空気は、ファン（25）を通過し、エアハンドリングユニット（2）の第２流出口（23）から第３ダクト（6）へ流入する。第３ダクト（6）へ流入した空気は、供給空気（SA）として各室内空間に搬送される。 The air that has passed through the first duct (4) flows in from the second inflow port (21) of the air handling unit (2) and passes through the heat exchanger (24). As the air passes through the heat exchanger (24), the temperature of the air is regulated. The temperature-controlled air passes through the fan (25) and flows into the third duct (6) from the second outlet (23) of the air handling unit (2). The air flowing into the third duct (6) is conveyed to each indoor space as supply air (SA).
　各室内空間の室内空気（RA）は、第２ダクト（5）に流入し、第２ダクト（5）を通過する。第２ダクト（5）を通過した空気は、エアハンドリングユニット（2）の第３流入口（22）から流入し、第２流入口（21）から流入した空気と混合されて、熱交換器（24）を通過する。その後の動作は、上述した通りである。 The indoor air (RA) in each indoor space flows into the second duct (5) and passes through the second duct (5). The air that has passed through the second duct (5) flows in from the third inlet (22) of the air handling unit (2), is mixed with the air that has flowed in from the second inlet (21), and is mixed with the air that has flowed in from the second inlet (21) to the heat exchanger ( 24) Pass. Subsequent operations are as described above.
　　　〈フィルタから被捕集物を除去する作業〉
　次に、フィルタユニット（40）に捕集された被捕集物を除去する作業について説明する。 <Work to remove the collected material from the filter>
Next, the work of removing the collected material collected by the filter unit (40) will be described.
　通常の運転動作中に、フィルタ（41）に多量の被捕集物が付着した場合、集塵ユニット（3）の差圧計（39）の計測値が大きくなる。差圧計（39）の計測値が大きい場合、あるいは所定の頻度（例えば、1日に1回）で、作業者はフィルタ（41）から被捕集物を除去する作業を行う。 If a large amount of collected material adheres to the filter (41) during normal operation, the measured value of the differential pressure gauge (39) of the dust collecting unit (3) becomes large. When the measured value of the differential pressure gauge (39) is large, or at a predetermined frequency (for example, once a day), the operator performs the work of removing the collected material from the filter (41).
　具体的には、作業者は集塵ユニット（3）のカバー（70）を取り外す。カバー（70）が取り外されると、第１リミットスイッチ（91）の接点が切れる。制御部（93）は、第１リミットスイッチ（91）の接点が切れたことに連動して、エアハンドリングユニット（2）のファン（25）を停止させる。言い換えると、停止装置（90）の制御部（93）は、除去機構（50）を作動させるための作業に連動して、ファン（25）を停止させる。 Specifically, the operator removes the cover (70) of the dust collecting unit (3). When the cover (70) is removed, the contact of the first limit switch (91) is cut off. The control unit (93) stops the fan (25) of the air handling unit (2) in conjunction with the disconnection of the contact of the first limit switch (91). In other words, the control unit (93) of the stop device (90) stops the fan (25) in conjunction with the work for operating the removal mechanism (50).
　ファン（25）が停止すると、空気通路（P）の空気の流れがなくなる。これにより、集塵ユニット（3）の吸込口（31）から室外空気（OA）が吸い込まれなくなる。 When the fan (25) stops, the air flow in the air passage (P) stops. As a result, the outdoor air (OA) is not sucked from the suction port (31) of the dust collecting unit (3).
　空気通路（P）の空気の流れがない状態で、作業者は操作部（60）を握り、手動で前後方向に操作部（60）を往復させる。操作部（60）の操作に伴って、連結部材（51）を介して、接触部材（52）が前後方向に移動する。このとき、移動した接触部材（52）は、フィルタ（41）の平面部（41a）に断続的に接触する。接触部材（52）がフィルタ（41）の平面部（41a）に接触すると、その衝撃でフィルタ（41）に付着した被捕集物が落下する（図２における白抜き矢印を参照）。落下した被捕集物は、受け部（80）に溜まる。 With no air flow in the air passage (P), the operator grasps the operation unit (60) and manually reciprocates the operation unit (60) in the front-rear direction. Along with the operation of the operation unit (60), the contact member (52) moves in the front-rear direction via the connecting member (51). At this time, the moved contact member (52) intermittently contacts the flat surface portion (41a) of the filter (41). When the contact member (52) comes into contact with the flat surface portion (41a) of the filter (41), the impact causes the collected material attached to the filter (41) to fall (see the white arrow in FIG. 2). The fallen collected material collects in the receiving part (80).
　作業者は、操作部（60）を前後方向に往復させる操作を数回繰り返した後、カバー（70）を第２ケーシング（30）に取り付ける。カバー（70）が取り付けられると、第１リミットスイッチ（91）の接点が繋がる。制御部（93）は、第１リミットスイッチ（91）の接点が繋がったことを示す信号を受信した後、所定時間経過後に、エアハンドリングユニット（2）のファン（25）を駆動させる。第１リミットスイッチ（91）の接点が繋がった後ファン（25）が駆動するまでに、所定の時間を空けることにより、集塵ユニット（3）の内部空間に巻き上がった被捕集物を受け部（80）へ完全に落下させることができる。 The operator repeats the operation of reciprocating the operation unit (60) in the front-rear direction several times, and then attaches the cover (70) to the second casing (30). When the cover (70) is attached, the contacts of the first limit switch (91) are connected. The control unit (93) drives the fan (25) of the air handling unit (2) after a predetermined time has elapsed after receiving the signal indicating that the contacts of the first limit switch (91) are connected. After the contacts of the first limit switch (91) are connected and the fan (25) is driven, a predetermined time is allowed to receive the collected material that has been rolled up in the internal space of the dust collecting unit (3). It can be completely dropped to the part (80).
　エアハンドリングユニット（2）のファン（25）が駆動すると、空気通路（P）に空気の流れが生じる。そして、集塵ユニット（3）の吸込口（31）から室外空気（OA）が再び吸い込まれる。 When the fan (25) of the air handling unit (2) is driven, an air flow is generated in the air passage (P). Then, the outdoor air (OA) is sucked in again from the suction port (31) of the dust collecting unit (3).
　　　〈受け部の清掃作業〉
　次に、受け部（80）の清掃作業について説明する。 <Cleaning work of receiving part>
Next, the cleaning work of the receiving portion (80) will be described.
　作業者は、所定の期間（例えば、１４日）経過後に、フィルタ（41）から除去されて受け部（80）に溜まった被捕集物を取り除く作業を行う。具体的には、作業者は、受け部（80）の取手部（81）を握り、受け部（80）を前方に引き出す。受け部（80）が移動すると、第２リミットスイッチ（92）の接点が切れる。制御部（93）は、第２リミットスイッチ（92）の接点が切れたことに連動して、エアハンドリングユニット（2）のファン（25）を停止させる。ファン（25）が停止すると、空気通路（P）の空気の流れがなくなる。これにより、集塵ユニット（3）の吸込口（31）から室外空気（OA）が吸い込まれなくなる。 After a predetermined period (for example, 14 days) has elapsed, the worker performs the work of removing the collected material that has been removed from the filter (41) and accumulated in the receiving portion (80). Specifically, the operator grasps the handle portion (81) of the receiving portion (80) and pulls out the receiving portion (80) forward. When the receiving portion (80) moves, the contact of the second limit switch (92) is cut off. The control unit (93) stops the fan (25) of the air handling unit (2) in conjunction with the disconnection of the contact of the second limit switch (92). When the fan (25) is stopped, the air flow in the air passage (P) is cut off. As a result, the outdoor air (OA) is not sucked from the suction port (31) of the dust collecting unit (3).
　空気通路（P）の空気の流れがない状態で、作業者は受け部（80）をさらに前方に引き出す。受け部（80）を引き出す際に、空気通路（P）の空気の流れがないので、受け部（80）に溜まった被捕集物が巻き上がることを抑制できる。作業者は、受け部（80）に溜まった被捕集物を取り除く。その後作業者は、被捕集物が取り除かれた受け部（80）を、再び集塵ユニット（3）に差し込む。 With no air flow in the air passage (P), the operator pulls out the receiving part (80) further forward. Since there is no air flow in the air passage (P) when the receiving portion (80) is pulled out, it is possible to prevent the collected material accumulated in the receiving portion (80) from being rolled up. The worker removes the collected material accumulated in the receiving part (80). After that, the worker inserts the receiving part (80) from which the collected object has been removed into the dust collecting unit (3) again.
　受け部（80）が集塵ユニット（3）に完全に収容されると、第２リミットスイッチ（92）の接点が繋がる。制御部（93）は、第２リミットスイッチ（92）の接点が繋がった後、エアハンドリングユニット（2）のファン（25）を駆動させる。具体的には、制御部（93）は、第２リミットスイッチ（92）の接点が繋がると、直ぐにエアハンドリングユニット（2）のファン（25）を駆動させる。ファン（25）が駆動すると、空気通路（P）に空気の流れが生じる。そして、集塵ユニット（3）の吸込口（31）から室外空気（OA）が再び吸い込まれる。 When the receiving part (80) is completely housed in the dust collecting unit (3), the contacts of the second limit switch (92) are connected. The control unit (93) drives the fan (25) of the air handling unit (2) after the contacts of the second limit switch (92) are connected. Specifically, the control unit (93) drives the fan (25) of the air handling unit (2) as soon as the contact of the second limit switch (92) is connected. When the fan (25) is driven, an air flow is created in the air passage (P). Then, the outdoor air (OA) is sucked in again from the suction port (31) of the dust collecting unit (3).

The air conditioning system (1) of the present embodiment includes a removal mechanism (50) for removing the collected material collected by the filter (41) from the filter (41).
　室外空気を調和する空気調和システムでは、室外空気中の被捕集物がフィルタに多量に付着することで、フィルタが詰まりやすい。特に、室外空気中に多くの被捕集物を含む地域では、短期間でフィルタが詰まってしまう。その結果、このような地域では、フィルタの交換頻度が高くなり、空気調和システムを維持するためのコストが高くなってしまう。 In an air conditioning system that harmonizes outdoor air, a large amount of collected material in the outdoor air adheres to the filter, which makes it easy for the filter to become clogged. Especially in areas where the outdoor air contains a large amount of collected material, the filter becomes clogged in a short period of time. As a result, filters are replaced more frequently in such areas, resulting in higher costs for maintaining an air conditioning system.
　本実施形態の空気調和システム（1）では、除去機構（50）によって、フィルタ（41）に付着した室外空気（OA）中の被捕集物が除去される。これにより、フィルタ（41）の集塵能力を速やかに回復できるので、フィルタ（41）の交換頻度を低減できる。その結果、空気調和システム（1）を維持するためのコストを低減できる。 In the air conditioning system (1) of the present embodiment, the collection mechanism (50) removes the collected material in the outdoor air (OA) adhering to the filter (41). As a result, the dust collecting capacity of the filter (41) can be quickly restored, so that the frequency of replacement of the filter (41) can be reduced. As a result, the cost for maintaining the air conditioning system (1) can be reduced.

　本実施形態の空気調和システム（1）では、接触部材（52）とフィルタ（41）とを接触させることにより、フィルタ（41）に衝撃を付与できる。この衝撃でフィルタ（41）に付着した被捕集物をフィルタ（41）から除去できる。具体的には、接触部材（52）とフィルタ（41）とを断続的に接触させることにより、フィルタ（41）に衝撃を付与する。 In the air conditioning system (1) of the present embodiment, an impact can be applied to the filter (41) by bringing the contact member (52) into contact with the filter (41). By this impact, the collected material adhering to the filter (41) can be removed from the filter (41). Specifically, an impact is applied to the filter (41) by intermittently contacting the contact member (52) and the filter (41).

In the modified example 1 of the first embodiment shown in FIG. 5, the structure of the filter (41) of the filter unit (40) is different from that of the above embodiment. The filter (41) in the first modification of the first embodiment has two flat portions (41a) and one continuous portion (41c). In other words, the filter (41) of the present modification does not have the side surface portion (41b) of the filter (41) of the first embodiment. The basic configuration and arrangement of the filter unit (40) of this modification is the same as that of the first embodiment.
　フィルタ（41）は、前側の平面部（41a）の右側端部（41d）と、後側の平面部（41a）の右側端部（41d）とが接合されている。フィルタ（41）は、前側の平面部（41a）の左側端部（41d）と、後側の平面部（41a）の左側端部（41d）とが接合されている。言い換えると、フィルタ（41）の各平面部（41a）は、左右方向において対応する端部（41d）同士が接合されている。各平面部（41a）の端部（41d）同士は、熱による溶着又は縫製によって接合されている。 In the filter (41), the right end portion (41d) of the front flat portion (41a) and the right end portion (41d) of the rear flat portion (41a) are joined. In the filter (41), the left end portion (41d) of the front flat portion (41a) and the left end portion (41d) of the rear flat portion (41a) are joined. In other words, each flat surface portion (41a) of the filter (41) is joined to the corresponding end portions (41d) in the left-right direction. The ends (41d) of the flat surfaces (41a) are joined by heat welding or sewing.
　フィルタ（41）の内部には、２つの平面部（41a,41a）と、１つの連続部（41c）との間に、内部空間（S）が形成される。各フィルタ（41）の２つの平面部（41a）の端部（41d）同士を接合することで内部空間（S）が形成されるので、各フィルタ（41）を簡単に製造することができる。 Inside the filter (41), an internal space (S) is formed between two flat portions (41a, 41a) and one continuous portion (41c). Since the internal space (S) is formed by joining the ends (41d) of the two flat surfaces (41a) of each filter (41), each filter (41) can be easily manufactured.
　　　〈変形例２〉
　図６に示す実施形態１の変形例２は、上記実施形態と除去機構（50）の構成が異なる。実施形態１の変形例２における除去機構（50）の接触部材（52）は、環状の部材である。本変形例の除去機構（50）の基本的な構成及び配置は、実施形態１と同様である。 <Modification 2>
The second modification of the first embodiment shown in FIG. 6 has a different configuration of the removal mechanism (50) from the above embodiment. The contact member (52) of the removal mechanism (50) in the second modification of the first embodiment is an annular member. The basic configuration and arrangement of the removal mechanism (50) of this modification is the same as that of the first embodiment.
　接触部材（52）は、丸棒を楕円形の環状になるように曲げて成形されている。接触部材（52）は、鉄などの金属材料で構成される。接触部材（52）は、左右方向を長径とし、上下方向を短径とする楕円形状である。接触部材（52）には、その前側と後側とにそれぞれ曲面状の接触部（52b）が形成される。接触部材（52）の前側及び後側の接触部（52b）は、フィルタ（41）の各平面部（41a）にそれぞれ対向する。接触部材（52）の各接触部（52b）は、対応するフィルタ（41）の各平面部（41a）と相対的な位置が変化する。接触部材（52）の各接触部（52b）は、対応するフィルタ（41）の各平面部（41a）と断続的に接触するように配置されている。 The contact member (52) is formed by bending a round bar into an elliptical ring shape. The contact member (52) is made of a metal material such as iron. The contact member (52) has an elliptical shape with a major axis in the left-right direction and a minor axis in the vertical direction. The contact member (52) is formed with curved contact portions (52b) on the front side and the rear side, respectively. The front and rear contact portions (52b) of the contact member (52) face each plane portion (41a) of the filter (41), respectively. Each contact portion (52b) of the contact member (52) changes its position relative to each planar portion (41a) of the corresponding filter (41). Each contact portion (52b) of the contact member (52) is arranged to be in intermittent contact with each planar portion (41a) of the corresponding filter (41).
　接触部材（52）は環状の部材なので、接触部材（52）が板状の部材である場合と比べて、除去機構（50）が軽い。このため、除去機構（50）を作動させる際、作業者の操作性が向上する。 Since the contact member (52) is an annular member, the removal mechanism (50) is lighter than when the contact member (52) is a plate-shaped member. Therefore, when the removal mechanism (50) is operated, the operability of the operator is improved.
　　　〈変形例３〉
　図７に示す実施形態１の変形例３は、上記実施形態と除去機構（50）の構成が異なる。実施形態１の変形例３の除去機構（50）は、１つの連結部材（51）と、複数の揺動部材（56）とを有する。実施形態１の変形例３の連結部材（51）の基本的な構成及び配置は、実施形態１と同様である。 <Modification example 3>
The modification 3 of the first embodiment shown in FIG. 7 has a different configuration of the removal mechanism (50) from the above embodiment.

The diameter of the cross section of the rocking member (56) is smaller than the diameter of the cross section of the connecting member (51). The length of the rocking member (56) in the left-right direction is longer than the length of the continuous portion (41c) of the filter (41) in the filter unit (40). The right end of each swing member (56) is connected to the connecting member (51). The rocking member (56) is attached to the outer peripheral surface of the continuous portion (41c) of the filter (41). The swinging member (56) is configured to be swingable via the connecting member (51).

In other words, the quantity of the rocking member (56) is the same as the quantity of the filter (41). The number of rocking members (56) is merely an example. The rocking member (56) corresponds to the second member.
　操作部（60）の操作に伴って、連結部材（51）を介して、揺動部材（56）は前後方向に揺動する。このとき、揺動部材（56）はフィルタ（41）の連続部（41c）に取り付けられているので、揺動部材（56）の前後方向の揺動に連動して、フィルタ（41）が揺動する。揺動部材（56）の動きに連動して、フィルタ（41）が揺動すると、その振動でフィルタ（41）に付着した被捕集物が落下する。 With the operation of the operation unit (60), the swing member (56) swings in the front-rear direction via the connecting member (51). At this time, since the swing member (56) is attached to the continuous portion (41c) of the filter (41), the filter (41) swings in conjunction with the swing in the front-rear direction of the swing member (56). Move. When the filter (41) swings in conjunction with the movement of the swing member (56), the collected material adhering to the filter (41) falls due to the vibration.

　　　〈変形例４〉
　図８に示す実施形態１の変形例４は、上記実施形態と複数のダクトの構成が異なるとともに、停止装置（90）の換わりに切替機構（10）を有する。実施形態１の変形例４における空気調和システム（1）の基本的な構成は、実施形態１と同様である。 <Modification example 4>

The basic configuration of the air conditioning system (1) in the fourth modification of the first embodiment is the same as that of the first embodiment.
　　　（ダクト）
　複数のダクト（4,5,6,7）は、第４ダクト（7）をさらに含む。第４ダクト（7）の流入端には、第３吸込口（7a）が形成される。第３吸込口（7a）は、室外に開口している。第３吸込口（7a）は、室外空気（OA）を吸い込む。第４ダクト（7）の流出端には、第３流出口（7b）が形成される。第３流出口（7b）は、第１ダクト（4）に連結されている。第４ダクト（7）は、室外空気（OA）を、集塵ユニット（3）を介さずに直接エアハンドリングユニット（2）に送る通路を構成する。 (duct)
The plurality of ducts (4,5,6,7) further include a fourth duct (7). A third suction port (7a) is formed at the inflow end of the fourth duct (7). The third suction port (7a) is open to the outside of the room. The third suction port (7a) sucks in outdoor air (OA). A third outlet (7b) is formed at the outflow end of the fourth duct (7). The third outlet (7b) is connected to the first duct (4). The fourth duct (7) constitutes a passage for sending the outdoor air (OA) directly to the air handling unit (2) without passing through the dust collecting unit (3).
　第３吸込口（7a）は、室内空気（RA）を吸い込む構成であってもよい。例えば、第３吸込口（7a）は、１つ又は複数の室内空間に開口してもよい。第４ダクト（7）は、室内空間と第１ダクト（4）とを連通させる。このとき、第４ダクト（7）は、室内空間の室内空気（RA）をエアハンドリングユニット（2）に戻す通路を構成する。 The third suction port (7a) may be configured to suck in indoor air (RA). For example, the third suction port (7a) may be opened in one or more indoor spaces. The fourth duct (7) communicates the indoor space with the first duct (4). At this time, the fourth duct (7) constitutes a passage for returning the indoor air (RA) in the indoor space to the air handling unit (2).
　　　（切替機構）
　切替機構（10）は、第１状態と第２状態とに切り替わる。切替機構（10）が第１状態であるとき、集塵ユニット（3）を経由した空気がエアハンドリングユニット（2）に送られる。具体的には、第１状態は、第１ダクト（4）と集塵ユニット（3）とを連通させるとともに第１ダクト（4）と室外とが遮断された状態である。切替機構（10）が第２状態であるとき、室外空気（OA）が直接エアハンドリングユニット（2）に送られる。具体的には、第２状態は、第１ダクト（4）と集塵ユニット（3）とが遮断されるとともに第１ダクト（4）と室外とを連通させた状態である。 (Switching mechanism)
The switching mechanism (10) switches between the first state and the second state. When the switching mechanism (10) is in the first state, the air that has passed through the dust collecting unit (3) is sent to the air handling unit (2). Specifically, the first state is a state in which the first duct (4) and the dust collecting unit (3) are communicated with each other and the first duct (4) and the outside are cut off. When the switching mechanism (10) is in the second state, outdoor air (OA) is sent directly to the air handling unit (2). Specifically, the second state is a state in which the first duct (4) and the dust collecting unit (3) are cut off and the first duct (4) and the outdoor are communicated with each other.
　切替機構（10）は、第１ダンパ（8）と第２ダンパ（9）とを有する。第１ダンパ（8）は、第１ダクト（4）に配置される。具体的には、第１ダンパ（8）は、第１空気通路（P1）の流出端（第１流出口（32））と第４ダクト（7）の流出端（第３流出口（7b））との間に配置される。第１ダンパ（8）は、第１ダクト（4）を開閉する。第１ダンパ（8）を開くと、第１空気通路（P1）の流出端（第１流出口（32））から第４ダクト（7）の流出端（第３流出口（7b））へ空気が流れる。第１ダンパ（8）を閉じると、第１空気通路（P1）の流出端（第１流出口（32））と第４ダクト（7）の流出端（第３流出口（7b））との間が遮断され、第１ダンパ（8）に空気が流れなくなる。 The switching mechanism (10) has a first damper (8) and a second damper (9). The first damper (8) is arranged in the first duct (4). Specifically, the first damper (8) is the outflow end (first outlet (32)) of the first air passage (P1) and the outflow end (third outlet (7b)) of the fourth duct (7). ) Is placed between. The first damper (8) opens and closes the first duct (4). When the first damper (8) is opened, air is blown from the outflow end (first outlet (32)) of the first air passage (P1) to the outflow end (third outlet (7b)) of the fourth duct (7). Flows. When the first damper (8) is closed, the outflow end (first outflow port (32)) of the first air passage (P1) and the outflow end (third outflow port (7b)) of the fourth duct (7) are connected. The space is cut off and air does not flow to the first damper (8).
　第２ダンパ（9）は、第４ダクト（7）に配置される。具体的には、第２ダンパ（9）は、第４ダクト（7）の第３吸込口（7a）と第３流出口（7b）との間に配置される。第２ダンパ（9）は、第４ダクト（7）を開閉する。第２ダンパ（9）を開くと、第４ダクト（7）の第３吸込口（7a）から第３流出口（7b）へ空気が流れる。第２ダンパ（9）を閉じると、第４ダクト（7）の第３吸込口（7a）と第３流出口（7b）との間が遮断され、第２ダンパ（9）に空気が流れなくなる。 The second damper (9) is arranged in the fourth duct (7). Specifically, the second damper (9) is arranged between the third suction port (7a) and the third outlet (7b) of the fourth duct (7). The second damper (9) opens and closes the fourth duct (7). When the second damper (9) is opened, air flows from the third suction port (7a) of the fourth duct (7) to the third outlet (7b). When the second damper (9) is closed, the space between the third suction port (7a) and the third outlet (7b) of the fourth duct (7) is cut off, and air does not flow to the second damper (9). ..
　なお、本変形例では、集塵ユニット（3）は、停止装置（90）を有しない。具体的には、集塵ユニット（3）は、カバー（70）、第１リミットスイッチ（91）、及び第２リミットスイッチ（92）を有しない。言い換えると、集塵ユニット（3）は、受け部（80）と制御部（93）とを有している。 In this modified example, the dust collecting unit (3) does not have a stop device (90). Specifically, the dust collecting unit (3) does not have a cover (70), a first limit switch (91), and a second limit switch (92). In other words, the dust collecting unit (3) has a receiving unit (80) and a control unit (93).
　　　（通常運転動作）
　通常の運転動作では、第１ダクト（4）の第１ダンパ（8）の開度が最大の状態であるとともに、第４ダクト（7）の第２ダンパ（9）が完全に閉じられた状態である。 (Normal operation operation)
In normal operation, the opening degree of the first damper (8) of the first duct (4) is the maximum, and the second damper (9) of the fourth duct (7) is completely closed. Is.
　室外空気（OA）が第１ダクト（4）に流入するまでの空気の流れは、実施形態１と同様である。第１ダクト（4）へ流入した空気は、第１ダンパ（8）を通過する。第１ダンパ（8）を通過した空気は、第４ダクト（7）の第２ダンパ（9）を通過することなく、第１ダクト（4）内をエアハンドリングユニット（2）に向かって流れる。エアハンドリングユニット（2）の第２流入口（21）に到達した後の空気の流れは、実施形態１と同様である。 The air flow until the outdoor air (OA) flows into the first duct (4) is the same as in the first embodiment. The air flowing into the first duct (4) passes through the first damper (8). The air that has passed through the first damper (8) flows in the first duct (4) toward the air handling unit (2) without passing through the second damper (9) of the fourth duct (7). The air flow after reaching the second inflow port (21) of the air handling unit (2) is the same as that in the first embodiment.
　　　（フィルタから被捕集物を除去する作業及び受け部の清掃作業）
　フィルタユニット（40）に捕集された被捕集物を除去する作業及び受け部（80）の清掃作業では、通常の運転動作中に、作業者は切替機構（10）を切り替える。具体的には、作業者は、第２ダンパ（9）の開度を最大にした後、第１ダンパ（8）を閉じる。これにより、ファン（25）が作動した状態で、第１空気通路（P1）の空気の流れがなくなり、集塵ユニット（3）の吸込口（31）から室外空気（OA）が吸い込まれなくなる。この後の第１空気通路（P1）の空気の流れがない状態で作業者が行う作業は、実施形態１と同様である。 (Work to remove the collected object from the filter and work to clean the receiving part)
In the work of removing the collected object collected by the filter unit (40) and the work of cleaning the receiving portion (80), the operator switches the switching mechanism (10) during the normal operation operation. Specifically, the operator closes the first damper (8) after maximizing the opening degree of the second damper (9). As a result, with the fan (25) operating, the air flow in the first air passage (P1) is eliminated, and the outdoor air (OA) is not sucked from the suction port (31) of the dust collecting unit (3). Subsequent work performed by the operator in the absence of air flow in the first air passage (P1) is the same as in the first embodiment.
　作業者は、操作部（60）を前後方向に往復させる操作を数回繰り返した後又は受け部（80）が集塵ユニット（3）に完全に収容された後、第１ダンパ（8）の開度を最大にする。その後、作業者は第２ダンパ（9）を閉じる。これにより、第１空気通路（P1）に空気の流れが生じ、集塵ユニット（3）の吸込口（31）から室外空気（OA）が再び吸い込まれる。 The operator of the first damper (8) after repeating the operation of reciprocating the operation unit (60) in the front-rear direction several times or after the receiving unit (80) is completely housed in the dust collecting unit (3). Maximize the opening. After that, the worker closes the second damper (9). As a result, an air flow is generated in the first air passage (P1), and the outdoor air (OA) is sucked in again from the suction port (31) of the dust collecting unit (3).
　切替機構（10）によって、集塵ユニット（3）の第１空気通路（P1）の空気の流れを止めることで、空気がフィルタ（41）を流れなくなる。このため、除去機構（50）を動作させる際、フィルタ（41）に捕集された被捕集物が空気によって巻き上げられることを抑制できる。ファン（25）が作動した状態で、フィルタから被捕集物を除去する作業及び受け部の清掃作業を行うことができる。集塵ユニット（3）のフィルタユニット（40）を交換する際においても、切替機構（10）を切り替えることで、ファン（25）を作動させた状態でフィルタユニット（40）の交換作業を行うことができる。 By stopping the air flow in the first air passage (P1) of the dust collecting unit (3) by the switching mechanism (10), the air does not flow through the filter (41). Therefore, when the removal mechanism (50) is operated, it is possible to prevent the collected object collected by the filter (41) from being wound up by air. With the fan (25) operating, the work of removing the collected object from the filter and the work of cleaning the receiving portion can be performed. Even when replacing the filter unit (40) of the dust collection unit (3), the filter unit (40) should be replaced while the fan (25) is operating by switching the switching mechanism (10). Can be done.
