In addition, an air conditioner is installed in a machine room provided in the back space of the building, and air supplied from the air conditioner is supplied to the blowout duct 1 via an underfloor pit (air supply duct). . Further, as shown in FIG. 14, the indoor stadium (air-conditioning target space) G is divided into a spectator seat (high density space) G1 having a high personnel density and a competition ground (low density space) G2 having a low personnel density. Shall.

  First, concrete is placed in a state in which cylindrical sleeves (not shown) having an inner diameter larger than the outer diameters of the units 2 to 8 are arranged at positions passing through the first step S1 and the second step S2. To form a floor and a through hole. Next, the units 2 to 8 are stacked, and the units 2 to 8 are connected. That is, the damper unit 8 is installed on the underfloor pit, and the fourth cavity unit 7 is stacked on the damper unit 8 while inserting the fourth cavity unit 7 into the sleeve of the first step S1. Then, the lower coupling ring of the fourth cavity unit 7 and the upper coupling ring 83 of the damper unit 8 are connected as described above.

  Similarly, the third cavity unit 6, the intermediate blowing unit 5, the second cavity unit 4, the first cavity unit 3 and the top blowing unit 2 are sequentially stacked and connected, and the blowing duct 1 is assembled. At this time, the second cavity unit 4 is stacked while being inserted into the sleeve of the second step S2. Subsequently, mortar is filled in the gap between the sleeve of the first step S1 and the fourth cavity unit 7 and the gap between the sleeve of the second step S2 and the second cavity unit 4. Then, the steady rest metal hardware welded to the upper side of the blowout duct 1 (on the top blowout unit 2 side) is welded to the hardware of the indoor stadium (for example, the hardware under the third step S3), and the blowout duct 1 is fixed. is there.

  In the state where the blowout duct 1 is installed in this manner, the intermediate blowout unit 5 is located immediately below the second staircase S2, and the top blowout unit 2 is located directly below the third staircase S3. That is, the intermediate blowing unit 5 is located above the first floor room F1, and the top blowing unit 2 is located above the second floor room F2. In other words, the first cavity unit 3, the second cavity unit 4, the intermediate outlet unit 5, the third cavity unit 6, and the fourth cavity so that the intermediate outlet unit 5 and the top outlet unit 2 are positioned in this way. The height of the cavity unit 7 is set (selected). Moreover, the upper part of the cylindrical body 21 of the partial blowout unit 2 is located in the ceiling board S3a disposed immediately below the third staircase S3, so that no gap is generated between the ceiling board S3a and the ceiling board S3a. In addition, you may make it the upper end part (entire upper cover 24) of the cylinder 21 contact | connect the ceiling board S3a.

  Further, the inspection ports of the first cavity unit 3 and the third cavity unit 6 are positioned above the second staircase S2 and the first staircase S1 at heights that are easy to inspect, respectively. The height is set. Further, the construction around the air supply duct connected to the damper unit 8 is performed as follows. That is, the air supply duct connected to the air conditioner is previously extended to the vicinity of the connection portion (lower end portion) of the damper unit 8, and the gap between the air supply duct and the connection portion is connected by a short pipe.

  As described above, a plurality of outlet ducts 1 are erected to construct an air conditioning facility. Here, as shown in FIG. 14, the opening 51A of the intermediate blowing unit 5 and the opening 21A of the top blowing unit 2 are directed to the spectator seat G1, and the air supply from the openings 51A, 21A is substantially horizontal radially toward the spectator seat G1. The blowout duct 1 is installed so that the blowout and the hollow spaces 51C and 21C are opposed to the wall portion in the indoor stadium. Furthermore, it is configured such that excess air from the spectator seat G1 flows into the competition ground G2. For example, an exhaust port is provided in the ceiling part of the competition ground G2, and air inside the competition ground G2 is directed to the exhaust port by a blower, and a part of the supply air supplied toward the spectator seat G1 flows into the competition ground G2. Let

  Next, the effect | action of the blowing duct 1 is demonstrated.

  First, the air supply from the air conditioner is supplied from the lower end side of the damper unit 8 to the hollow space 81A side via the underfloor pit, and according to the degree of opening and closing of the damper blade 84A of each air supply amount adjusting device 84. The supply air circulates in each hollow space 81A. Subsequently, the air that has circulated through each of the hollow spaces 81A sequentially flows through the fourth hollow unit 7 and the third hollow unit 6, and flows into the blowout space 51B and the hollow space 51C from the lower end of the intermediate blowout unit 5. To do. Here, since the inside of the fourth cavity unit 7 and the third cavity unit 6 is partitioned, the air supplied from each cavity space 81A is independently (separately) the fourth cavity unit. 7 and the third cavity unit 6 are circulated.

  Next, the supply air that has flowed into the blowing space 51 </ b> B is guided and direction-controlled by the guide plate 55, and blown out through the opening 51 </ b> A and the blowing shutter 53. Further, the supply air flowing into the cavity space 51C flows into the cavity space 41A of the second cavity unit 4 from the upper end of the cavity space 51C. Subsequently, the air supplied through the hollow space 41A flows into each hollow space 31A from the lower end side of the first hollow unit 3 and flows through each hollow space 31A from the lower end of the top blowing unit 2 to the blowing space 21B and It flows into the hollow space 21C. The supply air flowing into the blowing space 21B is guided and direction controlled by the guide plate 26, and blown out through the opening 21A and the blowing shutter 23. On the other hand, the flow of the supply air flowing into the hollow space 21 </ b> C is stopped by the partial upper lid 25.

  As described above, according to the blowout duct 1, the blowout duct 1 can be easily assembled and installed by simply stacking the units 2 to 8. Further, by arbitrarily combining the units 2 to 8 or selecting the hollow units 3 to 7 having an arbitrary height, the blowing duct 1 having a desired height is installed, or an opening is disposed at a desired position. It becomes possible to do. Moreover, by adjusting the units 2 to 8 after stacking, or by replacing some of the units 2 to 8 with other types or types (heights) of units 2 to 8, Etc. can be easily adjusted. In this way, the height and direction of the blowout can be adjusted arbitrarily, making it possible to deal with a wide variety of buildings. In other words, it is versatile, and mass production of units 2 to 8 can reduce costs. It becomes possible to plan.

  In addition, since the internal space of the blowout duct 1 is partitioned into the blowout space 1A and the hollow space 1B, it is possible to independently feed the air supply to each of the first floor room F1 and the second floor room F2 independently. Become. That is, when the internal space is not partitioned, if the blowing amount on the lower floor is reduced or blocked, the blowing amount on the upper floor is also reduced or blocked. On the other hand, in this blowout duct 1, even if the blowout amount blown out from the blowout space 1A to the lower floor is restricted or blocked, the air supply amount (air supply amount) to the hollow space 1B is not affected, and the upper floor is It becomes possible to feed the air supply well. For this reason, for example, even when the damper blade 84A of the air supply amount adjusting device 84 on the blowing space 1A side is closed and the third cavity unit 6 or the like is inspected, by supplying air to the cavity space 1B, The air supply to the second floor room F2 can be continued. In addition, since the air supply amount adjusting device 84 is provided on each of the blowing space 1A side and the hollow space 1B side, it is optional depending on the environment (temperature, humidity) of the first floor room F1 and the second floor room F2. The air supply amount can be blown out independently.
