FIG. 9A is a diagram viewed in a direction perpendicular to the depth direction, and FIG. 9B is a diagram viewed in a direction parallel to the depth direction. be.
　容器本体１０は、内部が垂直の仕切壁１１によって仕切られており、植物が栽培される栽培室１５と、栽培室１５に循環供給する気体を調節する空調室１７とを備えており、固定脚１０ａに支持されて地面に設置される。仕切壁１１には、栽培室１５から空調室１７に出入りするための扉である空調室出入扉１２が設置されている。 The container body 10 has an interior partitioned by a vertical partition wall 11, and includes a cultivation chamber 15 in which plants are cultivated, and an air conditioning chamber 17 for adjusting the gas circulating and supplied to the cultivation chamber 15. It is installed on the ground while being supported by 10a. The partition wall 11 is provided with an air-conditioned door 12 for entering and exiting the air-conditioned room 17 from the cultivation room 15 .
　また、容器本体１０は、床板１９を備え、栽培室１５及び空調室１７の床下には、床下気体循環往路２０を備えている。空調室１７で調節された調整気体は、床下気体循環往路２０を通って、栽培室１５全体へ徐々にゆっくりと均一に供給する。 In addition, the container body 10 is provided with a floor plate 19, and under the floors of the cultivation room 15 and the air conditioning room 17, an underfloor gas circulation outward path 20 is provided. The regulated gas adjusted in the air conditioning room 17 is gradually and uniformly supplied to the entire cultivation room 15 through the underfloor gas circulation outward path 20 .
　仕切壁１１の上部は開放されており、栽培室１５と空調室１７とがつながっている。したがって、床下気体循環往路２０から栽培室１５内へと送られた調整気体は、仕切壁１１の上方を通って空調室１７へと戻る。空調室１７内に戻った気体は、再度調節された後に、後述するエアコンディショナー７１によって再び床下気体循環往路２０へと送られ、圧力容器１０内を循環する。 The upper part of the partition wall 11 is open, and the cultivation room 15 and the air conditioning room 17 are connected. Therefore, the regulated gas sent into the cultivation room 15 from the outward underfloor gas circulation path 20 returns to the air conditioning room 17 through above the partition wall 11 . The gas that has returned to the air conditioning room 17 is again adjusted and sent to the underfloor gas circulation outbound path 20 again by the air conditioner 71 to be described later, and circulates inside the pressure vessel 10 .
　床下気体循環往路２０は、垂直壁である床下隔壁２４によって仕切られた、第一床下流路２１と、第二床下流路２２とを備えている。第一床下流路２１と第二床下流路２２は、空調室１７側から出入口扉５０側へと向かう奥行き方向に平行に延在して設置されている。図６や図８の断面図に示すように、第一床下流路２１が中央側に位置し、第二床下流路２２が第一床下流路２１の左右両側に分かれて位置している。 The outward underfloor gas circulation path 20 includes a first underfloor channel 21 and a second underfloor channel 22 partitioned by an underfloor partition wall 24, which is a vertical wall. The first underfloor channel 21 and the second underfloor channel 22 are installed so as to extend in parallel in the depth direction from the air conditioning room 17 side to the doorway door 50 side. As shown in the cross-sectional views of FIGS. 6 and 8 , the first underfloor channel 21 is located on the central side, and the second underfloor channel 22 is located on both left and right sides of the first underfloor channel 21 .
　第一床下流路２１は、中央に位置して左右を隔てる中央隔壁２５によって左側第一床下流路２１ａと右側第一床下流路２１ｂとの2つの部屋に分割されている。左側及び右側第一床下流路２１ａ，２１ｂは、栽培室１５の床下において、空調室１７側の上流側から出入口扉５０側の下流側まで奥行き方向全体がつながっており、それぞれ細長い1つの部屋となっている。 The first underfloor channel 21 is divided into two chambers, a left first underfloor channel 21a and a right first underfloor channel 21b, by a central partition 25 that separates the left and right in the center. The left and right first floor downstream channels 21a and 21b are connected in the entire depth direction under the floor of the cultivation room 15 from the upstream side of the air conditioning room 17 side to the downstream side of the entrance door 50 side, and are each a long and narrow room. It's becoming
　第二床下流路２２は、第一床下流路２１と第二床下流路２２との間に位置して奥行き方向に延在する流路隔壁２６によって、第一床下流路２１と仕切られている。左側第一床下流路２１ａの外側に左側第二床下流路２２ａ、右側第一床下流路２１ｂの外側に右側第二床下流路２２ｂが設置されている。 The second floor downstream channel 22 is separated from the first floor downstream channel 21 by a channel partition wall 26 positioned between the first floor downstream channel 21 and the second floor downstream channel 22 and extending in the depth direction. there is A left second underfloor channel 22a is provided outside the left first underfloor channel 21a, and a right second underfloor channel 22b is provided outside the right first underfloor channel 21b.
　第二床下流路２２は、奥行き方向において、所定の間隔毎に奥行き隔壁２７が設置されており、奥行き方向においてさらに小さな部屋に分割されている。奥行き隔壁２７によって仕切られた部屋同士はつながっておらず、分割された部屋の間で気体が移動することはできない。 The second floor underflow passage 22 is divided into smaller rooms in the depth direction by installing depth partitions 27 at predetermined intervals in the depth direction. The rooms partitioned by the depth partition 27 are not connected to each other, and gas cannot move between the partitioned rooms.
　流路隔壁２６には、第一床下流路２１と第二床下流路とを連通する通気穴２６ａが、奥行き方向において所定の間隔で形成されており、第一床下流路２１と第二床下流路２２との間で気体が移動可能である。第二床下流路２２の分割された1つの部屋あたり、2つの通気穴２６ａが形成されている。 In the channel partition wall 26, ventilation holes 26a that communicate the first floor downstream channel 21 and the second floor downstream channel are formed at predetermined intervals in the depth direction. Gas can move between the downstream channels 22 . Two ventilation holes 26a are formed for each divided room of the second floor downstream channel 22 .
　各通気穴２６ａには、ダンパー２９が設置されており、通気穴２６ａの開口の大きさを手動により調整自在である。ダンパー２９は、ダンパー回転ハンドル２９ａと、ダンパー回転軸２９ｂと、円板形状のダンパー本体２９ｃとを備えており、手動でダンパー回転軸２９ｂ周りにダンパー本体２９ｃを回動させることで、ダンパー２９の開度を調整し、通気穴２６ａの開口の大きさを調整することができる。 A damper 29 is installed in each ventilation hole 26a, and the size of the opening of the ventilation hole 26a can be manually adjusted. The damper 29 includes a damper rotating handle 29a, a damper rotating shaft 29b, and a disk-shaped damper main body 29c. By adjusting the degree of opening, the size of the opening of the ventilation hole 26a can be adjusted.
　このような構成の床下気体循環往路２０において、後述する空気調節システム７０の口調ダクト開口７５ａから送風される調節済みの調整気体は、まず、空調室１７側の端部から第一床下流路２１内の上流部に入り、内部を出入口扉５０側の下流側に向けて流れる。 In the outward underfloor gas circulation path 20 having such a configuration, the regulated gas blown from the tone duct opening 75a of the air conditioning system 70, which will be described later, first flows from the end on the side of the air conditioning room 17 to the first downfloor flow path 21. It enters the upstream part inside and flows toward the downstream side of the entrance door 50 inside.
　このとき、第一床下流路２１の外側に位置する流路隔壁２６に通気穴２６ａが形成されているため、下流側に向けて流れる調整気体のうちの一部は、各通気穴２６ａを通って水平方向に移動し、外側の第二床下流路２２内へと入る。 At this time, since ventilation holes 26a are formed in the channel partition wall 26 positioned outside the first floor under-floor channel 21, part of the adjustment gas flowing toward the downstream side passes through each of the ventilation holes 26a. and move horizontally to enter the second underfloor passage 22 on the outside.
　このように、第一床下流路２１内を上流側から下流側へ向けて奥行き方向に流れる調整気体は、下流側に進むにつれて、順次通気穴２６ａを通過し、徐々に第二床下流路２２内へと進む。 In this way, the adjustment gas flowing in the depth direction from the upstream side to the downstream side in the first floor downstream channel 21 sequentially passes through the ventilation holes 26a as it advances downstream, and gradually flows into the second floor downstream channel 22. proceed inside.
　ここで、上述したように、通気穴２６ａにはそれぞれダンパー２９が設置されており、各通気穴２６ａにおける第一床下流路２１から第二床下流路２２へ流入量を調整することができる。 Here, as described above, the damper 29 is installed in each ventilation hole 26a, and the amount of inflow from the first floor downstream channel 21 to the second floor downstream channel 22 in each ventilation hole 26a can be adjusted.
　本実施形態では、奥行き方向に所定の間隔で設置された通気穴２６ａに対して、気体循環の上流側の通気穴２６ａの開口を小さくし、下流側にいくにつれて、通気穴２６ａの開口が徐々に大きくなるように、各ダンパー２９の開度を調節している。 In this embodiment, the opening of the ventilation holes 26a on the upstream side of the gas circulation is made smaller than the ventilation holes 26a installed at predetermined intervals in the depth direction, and the openings of the ventilation holes 26a gradually increase toward the downstream side. The opening of each damper 29 is adjusted so that
　空気調節システム７０から調整気体が最初に供給される第一床下流路２１では、上流側の入口において気体の流れる速度である流速が大きく、下流側にいくに従って流速は小さくなる。したがって、通気穴２６ａの開口の大きさが上流側から下流側まで全て同じであると、上流側では多くの量の調整気体が通気穴２６ａを通過するのに対して、下流側では流速が小さい分、通気穴２６ａを通過する調整気体の量が少なくなってしまう。 In the first floor downstream channel 21 to which the regulated gas is initially supplied from the air conditioning system 70, the flow velocity, which is the velocity at which the gas flows, is high at the inlet on the upstream side, and the flow velocity decreases toward the downstream side. Therefore, if the opening sizes of the vent holes 26a are the same from the upstream side to the downstream side, a large amount of adjustment gas passes through the vent holes 26a on the upstream side, whereas the flow velocity is small on the downstream side. Accordingly, the amount of adjustment gas passing through the ventilation hole 26a is reduced.
　これでは、奥行き方向に複数の部屋に分割されている第二床下流路２２から栽培室１５内に流れ込む調整気体の量も上流側が多く、下流側が少なくなってしまい、結果として、栽培室１５内の全体に調整気体を均一に供給することができない。 In this case, the amount of regulated gas flowing into the cultivation chamber 15 from the second floor downstream channel 22 divided into a plurality of chambers in the depth direction is large on the upstream side and small on the downstream side. adjustment gas cannot be uniformly supplied to the entire
　これに対して、本実施形態のように、第一床下流路２１と第二床下流路２２との間の通気穴２６ａを上流側から下流側にいくに従って開口が大きくなるように調節することで、循環する調整気体の流速が小さくなる下流側においても、上流側と同量の調整気体を第二床下流路２２内に供給することができる。 On the other hand, as in the present embodiment, the ventilation hole 26a between the first floor downstream channel 21 and the second floor downstream channel 22 is adjusted so that the opening becomes larger from the upstream side to the downstream side. Therefore, even on the downstream side where the flow velocity of the circulating regulating gas is low, the same amount of regulating gas as on the upstream side can be supplied into the second floor downstream channel 22 .
　栽培室１５の床板１９は、第一床下流路２１の上面を含め、基本的に縞鋼板１９ａであり、栽培室１５等の床上と床下気体循環往路２０等の床下は遮断されている。しかし、第二床下流路２２の上には、複数の小孔１９ｃが形成されたパンチングメタル板１９ｂが設置されており、この小孔１９ｃにより、第二床下流路２２内と栽培室１５内とは、気体が移動可能につながっている。 The floor plate 19 of the cultivation room 15 is basically a checkered steel plate 19a, including the upper surface of the first floor downstream channel 21, and the floor of the cultivation room 15, etc. and the underfloor of the underfloor gas circulation outward path 20, etc. are blocked. However, above the second floor downstream channel 22, a punching metal plate 19b having a plurality of small holes 19c formed therein is installed. is movably connected to the gas.
　よって、通気穴２６ａから第二床下流路２２に入った調整気体は、パンチングメタル板１９ｂの小孔１９ｃを通って上昇し、栽培室１５内へと下方から流入する。第二床下流路２２は、奥行き隔壁２７によって、奥行き方向に複数の部屋に分割されており、第二床下流路２２の各部屋に入った調整気体は、奥行き方向には移動することなく、各部屋において、小孔１９ｃを通って、栽培室１５内へと上方向に流れる。 Therefore, the adjustment gas that has entered the second floor downstream channel 22 through the ventilation holes 26a rises through the small holes 19c of the punching metal plate 19b and flows into the cultivation chamber 15 from below. The second floor downstream channel 22 is divided into a plurality of chambers in the depth direction by the depth partition wall 27, and the adjustment gas entering each chamber of the second floor downstream channel 22 does not move in the depth direction, In each room, it flows upward into the cultivation room 15 through the small holes 19c.
　このように、第二床下流路２２を奥行き方向において奥行き隔壁２７によって分割することで、上流側から下流側にかけて開口の大きさが大きくなるように調整された通気穴２６ａを均等に通過した調整空気が第二床下流路２２内で奥行き方向に移動して混ざることなく、そのまま栽培室１５内全体に調整気体を均一に供給することができる。 In this way, by dividing the second floor underflow passage 22 in the depth direction by the depth partition wall 27, the ventilation holes 26a, which are adjusted so that the opening size increases from the upstream side to the downstream side, are evenly passed through. The adjustment gas can be uniformly supplied to the entire cultivation room 15 as it is without the air moving in the depth direction in the second underfloor channel 22 and being mixed.
　上述したように、仕切壁１１の上部は開放されており、第二床下流路２２から栽培室１５内に調整気体が流入すると、栽培室１５内の気体が順次仕切壁１１の上方を通って空調室１７内へと流れ込む。空調室１７に流れた気体は、空調室１７内で調整され、調整済みの調整気体が再びエアコンディショナー７１の空調ダクト開口７５ａから床下気体循環往路２０へと送り出される。 As described above, the upper portion of the partition wall 11 is open, and when the regulated gas flows into the cultivation chamber 15 from the second floor downstream channel 22, the gas in the cultivation chamber 15 sequentially passes above the partition wall 11. It flows into the air-conditioned room 17 . The gas that has flowed into the air conditioning room 17 is adjusted within the air conditioning room 17 , and the adjusted gas that has been adjusted is sent out again from the air conditioning duct opening 75 a of the air conditioner 71 to the outward underfloor gas circulation path 20 .
　このような容器本体１０内の気体の循環は、エアコンディショナー７１が備える送風ファンにより空調ダクト７５から送り出される調整気体の風圧によって実現される。風圧が弱く、気体が適切に循環しない場合には、別途、送風ファンを設置するようにしても良い。例えば、仕切壁１１の上方に、栽培室１５側から空調室１７へと向けて気体を送る送風ファンを設置することができる。 Such circulation of the gas in the container body 10 is realized by the wind pressure of the regulated gas sent out from the air conditioning duct 75 by the blower fan provided in the air conditioner 71 . If the wind pressure is weak and the gas does not circulate properly, a blower fan may be installed separately. For example, above the partition wall 11, a blower fan for sending gas from the cultivation room 15 side to the air conditioning room 17 can be installed.
　採光窓３０は、円形の窓であり、栽培室１５内に容器外から光を取り入れるために、容器本体１０の上部の所定の位置に複数設置されている。本実施形態では、容器本体１０の長手方向に平行に3列、合計16個の採光窓３０が規則的に配列されて設置されている。 The lighting windows 30 are circular windows, and a plurality of them are installed at predetermined positions on the top of the container body 10 in order to let light into the cultivation chamber 15 from outside the container. In this embodiment, a total of 16 lighting windows 30 are regularly arranged in three rows parallel to the longitudinal direction of the container body 10 .
　採光窓３０は、容器本体１０に固定される保持台３１と、保持台３１に固定保持される紫外線・赤外線カットガラス３５及び耐圧ガラス３７とを備えている。保持台３１は、略円筒形状であり、容器本体１０に溶接固定される土台３２を備えており、図１～図３においては、土台３２のみが描かれている。 The lighting window 30 includes a holding base 31 fixed to the container body 10 , and an ultraviolet/infrared cut glass 35 and a pressure-resistant glass 37 fixed and held on the holding base 31 . The holding base 31 has a substantially cylindrical shape and includes a base 32 welded and fixed to the container body 10. In FIGS. 1 to 3, only the base 32 is illustrated.
　保持台３１は、室内側から外側（下方から上方）に向けて、耐圧ガラス３７、紫外線・赤外線カットガラス３５を順次保持しており、外側端部である上端部に照明装置６０が設置される。 The holding table 31 sequentially holds the pressure-resistant glass 37 and the ultraviolet/infrared cut glass 35 from the indoor side to the outside (from the bottom to the top), and the lighting device 60 is installed at the upper end, which is the outer end. .
　出入口扉５０は、作業者が栽培室１５内に出入りするために設置されており、容器本体１０の端部の半球部に設置されている。出入口扉５０は、筒型補強枠５１と、筒型補強枠５１の開口を開閉する開閉扉である内開き扉５３と、扉引き締め部材９０とを備えている。 The entrance/exit door 50 is installed for the operator to enter and exit the cultivation room 15 and is installed in the hemispherical portion at the end of the container body 10 . The entrance/exit door 50 includes a cylindrical reinforcing frame 51 , an inward opening door 53 that opens and closes the opening of the cylindrical reinforcing frame 51 , and a door tightening member 90 .
　筒型補強枠５１は、容器本体１０の半球部に出入口を確保するために、容器本体１０の出入口用開口に固定設置される枠であり、枠内を人が通ることのできる長円形状（陸上競技のトラック形状）の筒型の枠である。 The cylindrical reinforcing frame 51 is a frame that is fixed to the entrance opening of the container body 10 in order to secure the entrance in the hemispherical portion of the container body 10, and has an oval shape ( It is a cylindrical frame in the shape of a track used in athletics.
　内開き扉５３は、板状の長円形状であり、筒型補強枠５１の内側（室内側）の端部開口を閉じるように、筒型補強枠５１に対して室内側に開く内開き構造で内側開口を開閉自在に構成されている。内開き扉５３は、筒型補強枠５１の内側端部に内開き扉５３を押し付けながら閉じるための密閉レバー５４を備えている。 The inward opening door 53 has a plate-like elliptical shape, and has an inward opening structure that opens toward the indoor side with respect to the tubular reinforcing frame 51 so as to close the end opening on the inner side (inside the room) of the tubular reinforcing frame 51. The inner opening is configured to be openable and closable. The inwardly opening door 53 has a sealing lever 54 for closing the inwardly opening door 53 while pressing it against the inner end of the cylindrical reinforcing frame 51 .
　本実施形態では、植物の栽培時に容器本体１０内が大気圧よりも高圧状態となるため、内開き扉５３を採用することで、閉じた状態では室内圧力により内開き扉５３が筒型補強枠５１の内側端部に押し付けられる。このとき、筒型補強枠５１の内側端部が内開き扉５３のパッキンに押し付けられるので、容器本体１０内を確実に密封することができる。 In this embodiment, since the pressure inside the container body 10 is higher than the atmospheric pressure during plant cultivation, the inwardly opening door 53 is employed, and when closed, the inwardly opening door 53 is opened by the pressure inside the cylindrical reinforcing frame. It is pressed against the inner end of 51 . At this time, the inner end of the cylindrical reinforcing frame 51 is pressed against the packing of the inwardly opening door 53, so that the inside of the container body 10 can be reliably sealed.

　以上、植物育成用圧力容器１の構成について説明したが、続いて、植物育成用圧力容器１の使用態様について説明する。植物の育成にあたっては、作業者が出入口扉５０を通って、所定の植物を容器本体１０内の栽培室１５内に運び込んで設置する。 The configuration of the plant-cultivating pressure vessel 1 has been described above. Next, the mode of use of the plant-cultivating pressure vessel 1 will be described. When growing a plant, an operator carries and installs a predetermined plant into the cultivation chamber 15 inside the container body 10 through the entrance door 50 .
　育成植物の設置作業後、作業者が容器本体１０の外に出て、出入口扉５０を閉めて容器本体１０内を密封した後、照明装置６０及び空気調節システム７０の駆動制御を行うことで、所定の気圧、所定の温度、所定の成分濃度の気体雰囲気、所定の照度及び照射時間の環境下で植物の育成を行うことができる。 After the installation work of the growing plant, the worker goes out of the container body 10, closes the entrance door 50 to seal the inside of the container body 10, and then controls the driving of the lighting device 60 and the air conditioning system 70. A plant can be grown under an environment of a predetermined atmospheric pressure, a predetermined temperature, a gaseous atmosphere with a predetermined component concentration, and a predetermined illuminance and irradiation time.
　例えば、気圧が2気圧、温度が20℃、成分比が酸素濃度約25％、二酸化炭素濃度約1,000ppm、窒素濃度約74.9％の環境下で植物の生育を行う場合には、エアコンディショナー７１の温度設定を栽培室１５内が20℃となるような所定の温度に設定すると共に、栽培室１５内の気圧が2気圧、気体の成分比が上記比率になるように気体成分・圧力調節装置８０を設定する。 For example, when growing plants in an environment with an atmospheric pressure of 2 atmospheres, a temperature of 20°C, and an oxygen concentration of approximately 25%, a carbon dioxide concentration of approximately 1,000 ppm, and a nitrogen concentration of approximately 74.9%, the air conditioner 71 The temperature is set to a predetermined temperature such that the inside of the cultivation room 15 is 20° C., the pressure inside the cultivation room 15 is 2 atm, and the gas component/pressure adjusting device 80 is operated so that the gas component ratio is the above ratio. set.
　そうすると、気体成分・圧力調節装置８０の駆動により、圧縮空気供給路８１、酸素供給路８２、二酸化炭素供給路８３及び窒素供給路８４から所定の量の圧縮空気、圧縮酸素、圧縮二酸化炭素及び圧縮窒素が空調室１７内に供給されると共に、排気路８５から所定の量の栽培室１５の気体が容器本体１０外に排出される。 Then, by driving the gas component/pressure adjusting device 80, a predetermined amount of compressed air, compressed oxygen, compressed carbon dioxide, and compressed Nitrogen is supplied into the air conditioning room 17 and a predetermined amount of gas in the cultivation room 15 is discharged from the container body 10 through the exhaust path 85 .
　平行して、エアコンディショナー７１が、空調室１７内の気体を取り入れて、所定の温度の調整気体に調節してから、空調ダクト７５を通して、調節済みの調整気体を床下気体循環往路２０に供給する。所定の時間経過すると、栽培室１５は、気圧が2気圧、室温が20℃、気体の成分比が所定の比率の環境に調節される。 In parallel, the air conditioner 71 takes in the gas in the air conditioning room 17, adjusts it to a regulated gas of a predetermined temperature, and then supplies the adjusted regulated gas to the underfloor gas circulation outbound path 20 through the air conditioning duct 75. . After a predetermined period of time has elapsed, the cultivation chamber 15 is adjusted to an environment in which the atmospheric pressure is 2 atm, the room temperature is 20° C., and the gas component ratio is a predetermined ratio.
　以上、本実施形態について説明したが、本実施形態によれば、床下気体循環往路２０を介して、栽培室１５と空調室１７との間で気体を循環させることで、栽培室１５内を所定の気圧、所定の温度、所定の成分濃度の気体雰囲気にすることができ、所望の環境下で植物の育成を行うことができる。 The present embodiment has been described above. According to the present embodiment, by circulating the gas between the cultivation room 15 and the air conditioning room 17 via the underfloor gas circulation outward path 20, the inside of the cultivation room 15 can be adjusted to a predetermined level. of atmospheric pressure, a predetermined temperature, and a predetermined concentration of components, and plants can be grown in a desired environment.
　また、本実施形態では、床下気体循環往路２０を栽培室１５の床下に設置すると共に、上流側が空調室１７と接続された第一床下流路２１と、通気穴２６ａが形成された流路隔壁２６を介して第一床下流路２１の隣に隣接設置された第二床下流路２２とを設置し、第二床下流路２２の天井に栽培室１５と連通する多数の小孔１９ｃを形成している。 In addition, in the present embodiment, the outward underfloor gas circulation path 20 is installed under the floor of the cultivation room 15, and the upstream side is connected to the air conditioning room 17, the first underfloor flow path 21, and the flow path partition in which the ventilation holes 26a are formed. A second floor downstream channel 22 is installed next to the first floor downstream channel 21 via 26, and a large number of small holes 19c communicating with the cultivation chamber 15 are formed in the ceiling of the second floor downstream channel 22. is doing.
　このため、空調室１７において調節された調整気体は、第一床下流路２１から通気穴２６ａを通って水平方向に移動し、その後、第二床下流路２２から小孔１９ｃを通って上方向に移動して栽培室１５内に入る。 Therefore, the regulated gas adjusted in the air-conditioning room 17 moves horizontally from the first floor underflow passage 21 through the ventilation holes 26a, and then moves upward from the second floor underflow passage 22 through the small holes 19c. to enter the cultivation room 15 .
　このように、床下気体循環往路２０において、調整気体が水平方向に移動してから垂直方向に移動して栽培室１５内に入ることで、調整気体の流れる速度が大幅に抑えられ、ゆっくりと栽培室１５内に入ることになる。 In this way, in the outward underfloor gas circulation path 20, the regulated gas moves in the horizontal direction and then in the vertical direction to enter the cultivation chamber 15, so that the flow speed of the regulated gas is greatly suppressed, and the cultivation can be performed slowly. You will enter the room 15.
　すなわち、エアコンディショナー７１から送風された調整気体が栽培室１５内の植物に直接当たることもなく、徐々に栽培室１５内の気体が調整気体に均一に置き換えられ、栽培室１５内に供給される調整気体の風圧により栽培室１５内の植物の生育に悪影響を及ぼすことを防ぐことができる。 That is, the regulated gas blown from the air conditioner 71 does not directly hit the plants in the cultivation room 15, and the gas in the cultivation room 15 is gradually uniformly replaced with the regulated gas and supplied into the cultivation room 15. It is possible to prevent the growth of plants in the cultivation chamber 15 from being adversely affected by the wind pressure of the regulated gas.
　また、本実施形態では、奥行き方向に所定の間隔で設置された通気穴２６ａに対して、気体循環の上流側の通気穴２６ａの開口を小さくし、下流側にいくにつれて、通気穴２６ａの開口が徐々に大きくなるように、各ダンパー２９の開度を調節しているため、上流側から下流側にかけて全ての通気穴２６ａを通過する調整気体の流量を均等にすることができ、栽培室１５内全体に均一に調整気体を循環させることができる。 Further, in this embodiment, the openings of the ventilation holes 26a on the upstream side of the gas circulation are made smaller with respect to the ventilation holes 26a installed at predetermined intervals in the depth direction, and the openings of the ventilation holes 26a become smaller toward the downstream side. Since the opening of each damper 29 is adjusted so that the is gradually increased, the flow rate of the adjustment gas passing through all the ventilation holes 26a from the upstream side to the downstream side can be made uniform, and the cultivation chamber 15 The adjustment gas can be uniformly circulated throughout the interior.
