　［第１実施形態］
　図１は、本実施形態に係る栽培ハウス１００の一例を示す正面図である。図２は、栽培ハウス１００の一例を示す側面図である。図１及び図２に示す栽培ハウス１００は、例えば屋外の地表Ｇ上に建てられ、主として太陽光等の自然光を取り入れることで植物Ｐの栽培を行う。植物Ｐとしては、例えばイチゴ等が挙げられるが、イチゴに限定されず、他の種類の植物であってもよい。栽培ハウス１００は、建屋１０と、栽培棚２０と、温調装置３０とを備える。 [First embodiment]
FIG. 1 is a front view showing an example of a cultivation house 100 according to this embodiment. FIG. 2 is a side view showing an example of the cultivation house 100. As shown in FIG. The cultivation house 100 shown in FIGS. 1 and 2 is built, for example, outdoors on the ground surface G, and cultivates plants P mainly by taking in natural light such as sunlight. Examples of the plant P include strawberries, but are not limited to strawberries and may be other types of plants. A cultivation house 100 includes a building 10 , a cultivation shelf 20 and a temperature controller 30 .
　建屋１０は、栽培対象となる植物Ｐを収容する。建屋１０は、植物Ｐが光合成を行うことが可能な波長の光を透過する。建屋１０は、例えばビニール、ガラス等の透明な材料を用いて形成される。建屋１０を構成する材料としては、上記に限定されず、植物Ｐが光合成を行うことが可能な波長の光を透過する材料であれば、他の材料が用いられてもよい。建屋１０は、骨組みとなるフレーム１１に展張された状態で配置される。建屋１０は、妻面となる正面部１０ａ及び背面部１０ｂと、側面部１０ｃ、１０ｄと、天井部１０ｅとを有する。建屋１０の正面部１０ａ、背面部１０ｂ又は側面部１０ｃ、１０ｄには、不図示の扉が配置される。 The building 10 houses plants P to be cultivated. The building 10 transmits light having a wavelength that allows the plants P to perform photosynthesis. The building 10 is formed using a transparent material such as vinyl or glass. The material constituting the building 10 is not limited to the above, and other materials may be used as long as the material transmits light having a wavelength that enables the plants P to perform photosynthesis. The building 10 is arranged in a stretched state on a frame 11 serving as a framework. The building 10 has a front portion 10a and a rear portion 10b, side portions 10c and 10d, and a ceiling portion 10e. Doors (not shown) are arranged on the front portion 10a, the rear portion 10b, or the side portions 10c and 10d of the building 10. FIG.
　建屋１０には、換気装置１２、遮光シート１３及び断熱カーテン１４が設けられる。換気装置１２は、建屋１０の外部の空気を内部に取り込み、建屋１０の内部の空気を外部に排出する。なお、建屋１０は、換気装置１２の下方の位置に天井部１０ｅに沿った内張が設けられた構成であってもよい。内張は、植物Ｐを収容する空間と、天井部１０ｅに沿った天井部分の空間とを仕切るように配置される。また、換気装置１２は、天井部分の空間に空気を取り込み、当該空間の空気を排出する。この構成により、換気装置１２が天井部分の空間に外気を取り込むことで、内張を介して植物Ｐを収容する空間の温調を行うことができる。 The building 10 is provided with a ventilation device 12, a light shielding sheet 13 and a heat insulating curtain 14. The ventilation device 12 takes in the air outside the building 10 and discharges the air inside the building 10 to the outside. In addition, the building 10 may have a configuration in which a lining along the ceiling 10 e is provided below the ventilation device 12 . The lining is arranged so as to separate the space for housing the plant P from the space of the ceiling portion along the ceiling portion 10e. In addition, the ventilator 12 draws air into the space of the ceiling portion and exhausts the air from the space. With this configuration, the ventilator 12 takes in outside air into the space of the ceiling portion, so that the temperature of the space in which the plant P is accommodated can be controlled via the lining.
　遮光シート１３は、例えば建屋１０の天井部１０ｅの下方に配置することができる。遮光シート１３は、太陽光等の光の少なくとも一部を反射又は吸収する。遮光シート１３は、例えば天井部１０ｅの下方の少なくとも一部を覆った被覆状態と、天井部１０ｅの下方を覆っていない開放状態とを切り替え可能であってもよい。 The light shielding sheet 13 can be arranged, for example, under the ceiling part 10e of the building 10. The light shielding sheet 13 reflects or absorbs at least part of light such as sunlight. The light shielding sheet 13 may be switchable, for example, between a covered state covering at least a portion of the lower portion of the ceiling portion 10e and an open state not covering the lower portion of the ceiling portion 10e.
　断熱カーテン１４は、例えば建屋１０の側面部１０ｃ、１０ｄの外側に配置することができる。断熱カーテン１４は、太陽光等の光の少なくとも一部を反射又は吸収する。断熱カーテン１４は、例えば側面部１０ｃ、１０ｄの少なくとも一部を覆った被覆状態と、側面部１０ｃ、１０ｄを覆っていない開放状態とを切り替え可能であってもよい。また、断熱カーテン１４は、太陽光が照射されない場合又は太陽光が弱い場合に、遮熱の役割を果たすことで、建屋１０の内外の熱の出入りを小さくすることができる。これにより、例えば夏季には建屋１０内の温度が高くなることを抑制でき、冬季には建屋１０内の温度が低くなることを抑制できる。 The heat insulating curtain 14 can be arranged outside the side parts 10c and 10d of the building 10, for example. The insulating curtain 14 reflects or absorbs at least a portion of light, such as sunlight. The heat-insulating curtain 14 may be switchable, for example, between a covered state covering at least a portion of the side portions 10c and 10d and an open state not covering the side portions 10c and 10d. In addition, the thermal insulation curtain 14 plays a role of a heat shield when the sunlight is not irradiated or when the sunlight is weak, so that the heat transfer between the inside and outside of the building 10 can be reduced. As a result, for example, it is possible to prevent the temperature inside the building 10 from rising in summer, and it is possible to prevent the temperature inside the building 10 from falling in winter.
　栽培棚２０は、建屋１０の内部に配置される。栽培棚２０は、植物Ｐを収容する収容空間Ｋを形成する。収容空間Ｋは、栽培棚２０により、建屋１０の内部に対して空気の流通が規制されるように区画された空間である。図３は、栽培棚２０の一例を示す図である。栽培棚２０は、植物Ｐが光合成を行うことが可能な波長の光を透過する。栽培棚２０は、例えばビニール、ガラス等の透明な材料を用いて形成される。栽培棚２０を構成する材料としては、上記に限定されず、植物Ｐが光合成を行うことが可能な波長の光を透過する材料であれば、他の材料が用いられてもよい。栽培棚２０は、天井部分２０Ｃに遮光シート２６が配置されてもよい。遮光シート２６は、太陽光等の光の少なくとも一部を反射又は吸収する。遮光シート２６は、栽培棚２０の天井部分を覆った被覆状態と、覆っていない開放状態とを切り替え可能であってもよい。 The cultivation shelf 20 is arranged inside the building 10 . Cultivation shelf 20 forms accommodation space K in which plants P are accommodated. The accommodation space K is a space partitioned by the cultivation shelf 20 so that air circulation to the interior of the building 10 is restricted. FIG. 3 is a diagram showing an example of the cultivation shelf 20. As shown in FIG. The cultivation shelf 20 transmits light having a wavelength that allows the plants P to perform photosynthesis. The cultivation shelf 20 is formed using a transparent material such as vinyl or glass. The material constituting the cultivation shelf 20 is not limited to the above, and other materials may be used as long as the material transmits light having a wavelength that enables the plants P to perform photosynthesis. A light shielding sheet 26 may be arranged on the ceiling portion 20C of the cultivation shelf 20 . The light shielding sheet 26 reflects or absorbs at least part of light such as sunlight. The light shielding sheet 26 may be switchable between a covering state covering the ceiling portion of the cultivation shelf 20 and an open state not covering the ceiling portion.
　栽培棚２０は、第１方向Ｄ１に長手となるように形成される。栽培棚２０は、１つの建屋１０内において、第１方向Ｄ１に対して水平面に沿って直交する第２方向Ｄ２に複数配置される。なお、第１方向Ｄ１及び第２方向Ｄ２は、それぞれ上下方向Ｄ３に直交する。栽培棚２０は、それぞれ第２方向Ｄ２に移動可能に設けられる。 The cultivation shelf 20 is formed so as to be longitudinal in the first direction D1. A plurality of cultivation racks 20 are arranged in one building 10 in a second direction D2 perpendicular to the first direction D1 along the horizontal plane. Note that the first direction D1 and the second direction D2 are orthogonal to the vertical direction D3. The cultivation shelves 20 are provided movably in the second direction D2.
　栽培棚２０には、脚部２０ａが設けられる。脚部２０ａの底部には、車輪２０ｂが設けられる。建屋１０の地面には、当該車輪２０ｂを第２方向Ｄ２に案内する不図示のレールが設けられる。車輪２０ｂを当該レールに沿って移動させることで、栽培棚２０が第２方向Ｄ２に移動可能となる。栽培棚２０を第２方向Ｄ２に移動させることにより、作業者が栽培棚２０の間に入るためのスペースを確保することができる。このため、建屋１０内の第２方向Ｄ２に栽培棚２０を効率的に配置することができる。 The cultivation shelf 20 is provided with legs 20a. A wheel 20b is provided at the bottom of the leg 20a. A rail (not shown) is provided on the ground of the building 10 to guide the wheel 20b in the second direction D2. By moving the wheel 20b along the rail, the cultivation shelf 20 can be moved in the second direction D2. By moving the cultivation racks 20 in the second direction D2, a space for the operator to enter between the cultivation racks 20 can be secured. Therefore, the cultivation shelf 20 can be efficiently arranged in the second direction D2 inside the building 10 .
　収容空間Ｋには、植栽容器２１が配置される。植栽容器２１は、植物Ｐ及び当該植物Ｐを植えるための土壌等が配置される。植栽容器２１は、例えば矩形状の箱型であり、栽培棚２０の長手方向（第１方向Ｄ１）に沿って配置される。植栽容器２１は、栽培棚２０において例えば第２方向Ｄ２の中央に配置される。 A planting container 21 is arranged in the housing space K. The planting container 21 is arranged with a plant P, soil for planting the plant P, and the like. The planting container 21 is, for example, a rectangular box shape, and is arranged along the longitudinal direction (first direction D1) of the cultivation shelf 20 . The planting container 21 is placed, for example, in the center of the cultivation shelf 20 in the second direction D2.
　栽培棚２０内には、気流形成装置２２、湿度調整装置２３、二酸化炭素濃度調整装置２４及び排水管２５が配置される。気流形成装置２２については、後述する。湿度調整装置２３は、収容空間Ｋの湿度を調整する。湿度調整装置２３は、収容空間Ｋの湿度を検出し、検出結果に応じて、収容空間Ｋに例えば噴霧上の水であるミストを供給する。二酸化炭素濃度調整装置２４は、収容空間Ｋの二酸化炭素の濃度を調整する。二酸化炭素濃度調整装置２４は、収容空間Ｋの二酸化炭素濃度を検出し、検出結果に応じて収容空間Ｋに二酸化炭素ガスを供給する。排水管２５は、収容空間Ｋに溜まった水を外部に排出する。 An air flow forming device 22, a humidity adjusting device 23, a carbon dioxide concentration adjusting device 24, and a drain pipe 25 are arranged in the cultivation shelf 20. The airflow forming device 22 will be described later. The humidity adjustment device 23 adjusts the humidity of the housing space K. The humidity adjusting device 23 detects the humidity of the accommodation space K, and supplies mist, which is sprayed water, to the accommodation space K according to the detection result. The carbon dioxide concentration adjusting device 24 adjusts the concentration of carbon dioxide in the accommodation space K. The carbon dioxide concentration adjustment device 24 detects the carbon dioxide concentration in the accommodation space K, and supplies carbon dioxide gas to the accommodation space K according to the detection result. The drain pipe 25 discharges the water accumulated in the housing space K to the outside.
　温調装置３０は、配管３１と、温調水供給装置３２とを有する。配管３１は、収容空間Ｋに配置される。温調装置３０は、配管３１に媒体である温調水を流通させて収容空間Ｋを温調する。なお、媒体としては、温調水に限定されず、空気よりも熱容量の大きい物質であれば、他の物質を用いることができる。 The temperature control device 30 has a pipe 31 and a temperature control water supply device 32 . The pipe 31 is arranged in the accommodation space K. As shown in FIG. The temperature control device 30 regulates the temperature of the accommodation space K by circulating temperature control water as a medium through the pipe 31 . The medium is not limited to temperature-controlled water, and other substances can be used as long as they have a larger heat capacity than air.
　配管３１は、第１方向Ｄ１に延びた状態で配置される。配管３１は、収容空間Ｋを温調するための温調水を流通させる。配管３１は、例えばアルミニウム、ステンレス等の金属又は合金を用いて形成されてもよいし、熱伝導率が高い樹脂材料を用いて形成されてもよい。配管３１は、植栽容器２１に対して第２方向Ｄ２の側方に配置される。配管３１は、植物Ｐに照射される光を遮らないように、例えば植物Ｐの高さを超えない高さ位置に配置される。 The pipe 31 is arranged while extending in the first direction D1. The piping 31 circulates temperature-controlled water for temperature-controlling the housing space K. As shown in FIG. The pipe 31 may be formed using a metal such as aluminum or stainless steel or an alloy, or may be formed using a resin material with high thermal conductivity. The pipe 31 is arranged on the side of the planting container 21 in the second direction D2. The pipe 31 is arranged at a height position not exceeding the height of the plant P, for example, so as not to block the light irradiated to the plant P.
　配管３１は、１つの栽培棚２０において複数設けられる。なお、配管３１は、１つの栽培棚２０に１つ設けられた構成であってもよい。本実施形態では、例えば５本の配管３１が設けられた構成であるが、これに限定されず、４本以下又は６本以上であってもよい。以下、５本の配管を区別する場合、それぞれ配管３１ａ、３１ｂ、３１ｃ、３１ｄと表記する。 A plurality of pipes 31 are provided on one cultivation shelf 20 . In addition, the structure provided one piping 31 in one cultivation shelf 20 may be sufficient. In this embodiment, for example, five pipes 31 are provided. Hereinafter, when distinguishing five pipes, they are described as pipes 31a, 31b, 31c, and 31d, respectively.
　配管３１ａ、３１ｂは、植栽容器２１に対して第２方向Ｄ２の一方側に配置される。配管３１ａ、３１ｂは、栽培棚２０に対して第２方向Ｄ２に離れた位置に配置される。配管３１ａ、３１ｂは、例えば上下に並んだ状態で配置される。 The pipes 31a and 31b are arranged on one side of the planting container 21 in the second direction D2. The pipes 31a and 31b are arranged at positions separated from the cultivation shelf 20 in the second direction D2. The pipes 31a and 31b are arranged vertically, for example.
　配管３１ｃ、３１ｄは、植栽容器２１に対して第２方向Ｄ２の他方側に配置される。配管３１ｃ、３１ｄは、栽培棚２０に対して第２方向Ｄ２に離れた位置に配置される。配管３１ｃ、３１ｄは、例えば上下に並んだ状態で配置される。 The pipes 31c and 31d are arranged on the other side of the planting container 21 in the second direction D2. The pipes 31c and 31d are arranged at positions separated from the cultivation shelf 20 in the second direction D2. The pipes 31c and 31d are arranged vertically, for example.
　配管３１は、例えばフィン３１ｆを有する構成であってもよい。フィン３１ｆは、配管３１からの放熱を促進させる。フィン３１ｆが設けられることにより、収容空間Ｋの温調をより効率的に行うことができる。 The pipe 31 may be configured to have fins 31f, for example. The fins 31 f promote heat dissipation from the pipe 31 . By providing the fins 31f, the temperature control of the accommodation space K can be performed more efficiently.
　気流形成装置２２は、配管３１ａ、３１ｃの下方にそれぞれ配置される。気流形成装置２２は、例えば植物Ｐに照射される光を遮らないように、植物Ｐよりも下側の高さ位置に配置される。気流形成装置２２は、配管３１ａ、３１ｃに向けて空気の流れを形成する。気流形成装置２２としては、例えばファン等が用いられる。気流形成装置２２は、収容空間Ｋにおいて配管３１ａ、３１ｂ、３１ｃ、３１ｄに空気を吹き付けることで、配管３１ａ、３１ｂ、３１ｃ、３１ｄと収容空間Ｋの空気と間で積極的に熱交換を行わせる。これにより、収容空間Ｋの温調効率が向上する。 The airflow forming devices 22 are arranged below the pipes 31a and 31c. The airflow forming device 22 is arranged at a height position lower than the plant P so as not to block the light irradiating the plant P, for example. The airflow forming device 22 forms airflow toward the pipes 31a and 31c. For example, a fan or the like is used as the airflow forming device 22 . The airflow forming device 22 blows air onto the pipes 31a, 31b, 31c, and 31d in the accommodation space K, thereby actively exchanging heat between the pipes 31a, 31b, 31c, and 31d and the air in the accommodation space K. . Thereby, the temperature control efficiency of the accommodation space K is improved.
　図４は、温調装置３０の一例を模式的に示す平面図である。図４では、各栽培棚２０に配置される複数の配管３１を１本として示している。温調水供給装置３２は、温調水の温度を調整し、基管３５及び供給ヘッダー管３３を介して配管３１に供給する。また、温調水供給装置３２は、配管３１を流通した温調水を、回収ヘッダー管３４及び合流管３６を介して回収する。温調水供給装置３２は、回収した温調水を温調し、再び供給ヘッダー管３３を介して配管３１に供給する。このように、温調水供給装置３２は、供給ヘッダー管３３及び回収ヘッダー管３４を介して、配管３１を循環するように温調水を流通させる。温調水供給装置３２としては、例えばターボ冷凍機等を用いることができる。温調水供給装置３２は、例えば不図示の温調水貯留部等に貯留される温調水を取り込んで使用する構成とすることができる。 FIG. 4 is a plan view schematically showing an example of the temperature control device 30. FIG. In FIG. 4, the plurality of pipes 31 arranged on each cultivation shelf 20 are shown as one. The temperature-controlled water supply device 32 adjusts the temperature of the temperature-controlled water and supplies it to the pipe 31 via the base pipe 35 and the supply header pipe 33 . The temperature-controlled water supply device 32 also collects the temperature-controlled water that has flowed through the pipe 31 via a collection header pipe 34 and a junction pipe 36 . The temperature-controlled water supply device 32 temperature-controls the collected temperature-controlled water and supplies it to the pipe 31 through the supply header pipe 33 again. Thus, the temperature-controlled water supply device 32 circulates the temperature-controlled water through the pipes 31 via the supply header pipe 33 and the recovery header pipe 34 . As the temperature-controlled water supply device 32, for example, a centrifugal chiller or the like can be used. The temperature-controlled water supply device 32 can be configured to take in and use temperature-controlled water stored in, for example, a temperature-controlled water storage unit (not shown).
　温調水供給装置３２は、例えば栽培棚２０の外部に配置される。供給ヘッダー管３３は、基管３５を介して温調水供給装置３２に接続される。回収ヘッダー管３４は、合流管３６を介して温調水供給装置３２に接続される。供給ヘッダー管３３及び回収ヘッダー管３４は、栽培棚２０の内部に配置されてもよいし、栽培棚２０の外部に配置されてもよい。本実施形態では、供給ヘッダー管３３及び回収ヘッダー管３４が複数の栽培棚２０を第１方向Ｄ１に貫通して配置された構成を例に挙げているが、この構成に限定されず、栽培棚２０の外部に配置された構成であってもよい。 The temperature-controlled water supply device 32 is arranged outside the cultivation shelf 20, for example. The supply header pipe 33 is connected to the temperature-controlled water supply device 32 via the base pipe 35 . The recovery header pipe 34 is connected to the temperature-controlled water supply device 32 via a junction pipe 36 . The supply header pipe 33 and the recovery header pipe 34 may be arranged inside the cultivation shelf 20 or may be arranged outside the cultivation shelf 20 . In the present embodiment, a configuration in which the supply header pipes 33 and the recovery header pipes 34 are arranged to penetrate the plurality of cultivation shelves 20 in the first direction D1 is taken as an example, but the present invention is not limited to this configuration. 20 may be arranged outside.
　温調水供給装置３２は、例えば各配管３１に対して、第１方向Ｄ１の同一方向（図４では上方向）に温調水を流通させることができる。この構成では、熱媒体として空気よりも熱容量の大きい温調水が用いられるため、温調水が第１方向Ｄ１に配管を流通する場合において、収容空間Ｋを十分に温調可能である。なお、温調水供給装置３２は、例えば複数の配管３１のうち少なくとも２つの配管３１の間で第１方向Ｄ１の反対方向に温調水を流通させる構成であってもよい。温調水供給装置３２は、例えば図３等に示す配管３１ａと配管３１ｂとで第１方向Ｄ１の反対方向に温調水を流通させる構成であってもよい。また、温調水供給装置３２は、例えば配管３１ｃと配管３１ｄとで第１方向Ｄ１の反対方向に温調水を流通させる構成であってもよい。 The temperature-controlled water supply device 32 can circulate the temperature-controlled water in the same direction as the first direction D1 (upward in FIG. 4) to each pipe 31, for example. In this configuration, temperature-controlled water, which has a larger heat capacity than air, is used as the heat medium, so that the accommodation space K can be sufficiently temperature-controlled when the temperature-controlled water flows through the pipe in the first direction D1. Note that the temperature-controlled water supply device 32 may be configured to circulate the temperature-controlled water in the direction opposite to the first direction D1, for example, between at least two pipes 31 among the plurality of pipes 31 . The temperature-controlled water supply device 32 may have a configuration in which the temperature-controlled water is circulated in the direction opposite to the first direction D1, for example, by pipes 31a and 31b shown in FIG. 3 and the like. Further, the temperature-controlled water supply device 32 may be configured to circulate the temperature-controlled water in the direction opposite to the first direction D1, for example, by the pipes 31c and 31d.
　上記のように構成された栽培ハウス１００においては、植栽容器２１に土壌及び植物Ｐを配置して収容空間Ｋに収容する。温調水供給装置３２は、温調水を取り込んで所定の温度に温調しておく。この状態で、栽培棚２０に配置される配管３１に対して温調水供給装置３２から温調水を流通させる。配管３１の内部を温調水が流通すると、配管３１を介して温調水と収容空間Ｋの空気との間で熱交換が行われ、収容空間Ｋが温調される。このように、温調媒体として温調水が用いられるため、収容空間Ｋが効率的に温調される。 In the cultivation house 100 configured as described above, the soil and the plant P are arranged in the planting container 21 and housed in the housing space K. The temperature-controlled water supply device 32 takes in the temperature-controlled water and adjusts the temperature to a predetermined temperature. In this state, temperature-controlled water is circulated from the temperature-controlled water supply device 32 to the pipe 31 arranged on the cultivation shelf 20 . When the temperature-controlled water flows through the pipe 31, heat is exchanged between the temperature-controlled water and the air in the accommodation space K via the pipe 31, and the temperature of the accommodation space K is adjusted. Since the temperature control water is used as the temperature control medium in this manner, the temperature of the accommodation space K is efficiently controlled.

　［第２実施形態］
　図５は、第２実施形態に係る栽培ハウス２００の一例を示す図である。栽培ハウス２００は、収容空間Ｋにおける配管３１の配置が第１実施形態とは異なるため、当該相違点を中心に説明する。 [Second embodiment]
FIG. 5 is a diagram showing an example of a cultivation house 200 according to the second embodiment. Since the cultivation house 200 differs from the first embodiment in the arrangement of the pipes 31 in the housing space K, the difference will be mainly described.
　図５に示すように、本実施形態において、配管３１は、植栽容器２１に対して第２方向Ｄ２の一方側（図５の左側）であって、植栽容器２１に近接する位置に配置される配管３１ｅを有する。配管３１ｅは、植栽容器２１に対して第２方向Ｄ２の他方側に配置されてもよい。また、配管３１ｅは、平面視において植栽容器２１に重なる位置に配置されてもよい。 As shown in FIG. 5, in the present embodiment, the pipe 31 is arranged on one side of the planting container 21 in the second direction D2 (the left side in FIG. 5) and at a position close to the planting container 21. It has a pipe 31e to be connected. The pipe 31e may be arranged on the other side of the planting container 21 in the second direction D2. Further, the pipe 31e may be arranged at a position overlapping the planting container 21 in plan view.
　配管３１ｅには、植物Ｐとの間に熱伝導シート（熱伝導部材）４０が掛け渡される。この構成により、配管３１ｅから熱伝導シート４０を介した熱伝達により植物Ｐの温調を行うことができる。また、例えば植物Ｐが成長して熱伝導シート４０の巻き掛け位置がずれた場合でも、容易に巻き掛け位置を調整することができる。熱伝導シート４０は、例えば面ファスナーで固定することにより、配管３１に対して容易に着脱可能となる。なお、配管３１ｅと植物Ｐとの間に掛け渡される熱伝導部材としては、熱伝導シート４０等のシート状の構成には限定されず、例えば紐状の構成等のようにフレキシブル性を有する他の構成であってもよいし、剛体であってもよい。 A heat-conducting sheet (heat-conducting member) 40 is stretched between the pipe 31e and the plant P. With this configuration, the temperature of the plant P can be controlled by heat transfer from the pipe 31e through the heat conductive sheet 40. As shown in FIG. In addition, for example, even if the plant P grows and the wrapping position of the heat conductive sheet 40 shifts, the wrapping position can be easily adjusted. The heat conductive sheet 40 can be easily attached to and detached from the pipe 31 by fixing it with, for example, a hook-and-loop fastener. Note that the heat-conducting member that is stretched between the pipe 31e and the plant P is not limited to a sheet-like configuration such as the heat-conducting sheet 40, and may have flexibility such as a string-like configuration. or a rigid body.
　図６は、本実施形態に係る栽培ハウス２００の一例を模式的に示す平面図である。図６に示すように、植栽容器２１には、植物Ｐが第１方向Ｄ１に並んだ状態で配置される。配管３１ｅは、植栽容器２１の長手方向である第１方向Ｄ１に沿って配置される。配管３１ｅは、複数の植物Ｐのそれぞれとの距離ｄが均一になるように配置される。この場合、複数の植物Ｐに対して均一な長さの熱伝導シート４０を用いることができる。 FIG. 6 is a plan view schematically showing an example of the cultivation house 200 according to this embodiment. As shown in FIG. 6, in the planting container 21, plants P are arranged in a row in the first direction D1. The pipe 31 e is arranged along the first direction D<b>1 that is the longitudinal direction of the planting container 21 . The pipe 31e is arranged so that the distance d from each of the plurality of plants P is uniform. In this case, a heat conductive sheet 40 having a uniform length can be used for a plurality of plants P.
　図７は、熱伝導シート４０の一例を模式的に示す図である。図７に示すように、熱伝導シート４０は、接触部材４１及び被覆部材４２を有する。接触部材４１は、熱伝導シート４０を配管３１ｅと植物Ｐとの間に掛け渡した場合に、内周側に配置されて植物Ｐ及び配管３１ｅに接触する。接触部材４１は、例えば熱伝導率の高い材料を用いて形成される。被覆部材４２は、熱伝導シート４０を配管３１ｅと植物Ｐとの間に掛け渡した場合に、外周側に配置されて接触部材４１を覆う。被覆部材４２は、接触部材４１よりも熱伝導率が低くなるように形成される。被覆部材４２は、接触部材４１の外周側において収容空間Ｋの空気との間で熱交換が行われることを抑制する。 FIG. 7 is a diagram schematically showing an example of the heat conductive sheet 40. FIG. As shown in FIG. 7, the heat conductive sheet 40 has contact members 41 and covering members 42 . The contact member 41 is arranged on the inner peripheral side and comes into contact with the plant P and the pipe 31e when the heat conductive sheet 40 is stretched between the pipe 31e and the plant P. As shown in FIG. The contact member 41 is formed using, for example, a material with high thermal conductivity. The covering member 42 is arranged on the outer peripheral side to cover the contact member 41 when the heat conductive sheet 40 is stretched between the pipe 31e and the plant P. The covering member 42 is formed to have lower thermal conductivity than the contact member 41 . The covering member 42 suppresses heat exchange with the air in the accommodation space K on the outer peripheral side of the contact member 41 .
　配管３１ｅと植物Ｐとの間が熱伝導シート４０により接続されるため、熱伝導シート４０を介した熱伝導により植物Ｐの温調を行うことができる。例えば植物Ｐのうち土壌から延び出す根元部ＰＣと、配管３１ｅとの間に熱伝導シート４０を巻き付けることにより、根元部ＰＣの温調を効率的に行うことができる。本実施形態において、根元部ＰＣは、例えばクラウンを含む部分である。このため、クラウンを含む根元部ＰＣの温調を効率的に行うことができる。 Since the pipe 31e and the plant P are connected by the heat conductive sheet 40, the temperature of the plant P can be controlled by heat conduction through the heat conductive sheet 40. For example, by wrapping the heat conductive sheet 40 between the root portion PC of the plant P that extends from the soil and the pipe 31e, the temperature of the root portion PC can be efficiently controlled. In this embodiment, the base portion PC is a portion including, for example, a crown. Therefore, it is possible to efficiently control the temperature of the base portion PC including the crown.
　以上のように、本実施形態に係る栽培ハウス２００は、植物Ｐと配管３１との間に掛け渡される熱伝導シート４０を更に備える。したがって、収容空間Ｋの温調を行うための配管３１を用いて植物Ｐの温調を行うことができる。このため、植物Ｐの温調を効率的に行うことができる。 As described above, the cultivation house 200 according to the present embodiment further includes the heat conductive sheet 40 that spans between the plants P and the pipes 31. Therefore, the temperature of the plant P can be controlled using the piping 31 for controlling the temperature of the accommodation space K. Therefore, the temperature control of the plant P can be efficiently performed.
　本実施形態に係る栽培ハウス２００において、熱伝導シート４０は、接触部材４１と被覆部材４２との二重構造を有している。接触部材４１は、植物Ｐ及び配管３１に接する接触部材４１と、接触部材４１よりも熱伝導率が低い被覆部材４２とで覆われる。したがって、接触部材４１の外周側において、収容空間Ｋの空気との間で熱交換が行われることを抑制することができる。 In the cultivation house 200 according to this embodiment, the heat conductive sheet 40 has a double structure of the contact member 41 and the covering member 42 . The contact member 41 is covered with the contact member 41 that contacts the plant P and the pipe 31 and the covering member 42 that has lower thermal conductivity than the contact member 41 . Therefore, heat exchange with the air in the housing space K can be suppressed on the outer peripheral side of the contact member 41 .
　本実施形態に係る栽培ハウス２００において、配管３１ｅは、複数の植物Ｐのそれぞれとの距離が均一になるように配置される。したがって、複数の植物Ｐに対して均一な長さの熱伝導シート４０を用いることができる。 In the cultivation house 200 according to the present embodiment, the pipes 31e are arranged so that the distances from each of the plurality of plants P are uniform. Therefore, the thermally conductive sheet 40 having a uniform length can be used for a plurality of plants P.
　本実施形態に係る栽培ハウス２００において、熱伝導部材４０は、植物Ｐのうち土壌から延び出す根元部ＰＣと配管３１ｅとの間に掛け渡される。したがって、根元部ＰＣの温調を効率的に行うことができる。例えば、根元部ＰＣがクラウンを含む場合、クラウンを含む根元部ＰＣの温調を効率的に行うことができる。 In the cultivation house 200 according to the present embodiment, the heat conducting member 40 is spanned between the root portion PC of the plant P extending from the soil and the pipe 31e. Therefore, it is possible to efficiently control the temperature of the base portion PC. For example, when the root PC includes a crown, the temperature of the root PC including the crown can be efficiently controlled.

With this configuration, water droplets and the like condensed on the surface of the pipe 31 can be collected at the end of the housing space K in the first direction D1. For example, by arranging the drain pipe 25 at the end, the water droplets condensed in the accommodation space K are efficiently discharged to the outside of the accommodation space K.
　以上のように、第１実施形態に係る栽培ハウス１００は、光を透過する建屋１０と、建屋１０の内部に配置され、栽培対象となる植物Ｐを収容し建屋１０の内部に対して空気の流通が規制されるように区画された収容空間Ｋを形成する栽培棚２０と、収容空間Ｋに配置される配管３１を有し、配管３１に空気よりも熱容量の大きい温調水を流通させて収容空間Ｋを温調する温調装置３０とを備える。したがって、温調媒体として温調水を用いることにより、温調空気を用いる場合に比べて効率的に収容空間Ｋを温調することができる。これにより、温調効率を高めることが可能な栽培ハウス１００を提供することができる。 As described above, the cultivation house 100 according to the first embodiment includes the building 10 that transmits light, and the plant P to be cultivated, which is placed inside the building 10, and air is supplied to the inside of the building 10.

Therefore, by using the temperature-controlled water as the temperature-controlled medium, the temperature of the housing space K can be controlled more efficiently than when the temperature-controlled air is used. Accordingly, it is possible to provide the cultivation house 100 capable of improving temperature control efficiency.
