施設園芸農家では、温室や暖房設備等を用いて作物に最も適した環境や温度域を人工的に作り出すことにより、１年を通して多品種の作物を栽培することが可能である。しかし、燃料価格の上昇による生産コストの増加は、農家経営に大きな影響を与えている。また、地球温暖化防止策としての温室ガスの排出量の削減も重要な課題となっている。そのため、施設園芸農家においては、生産管理、生産設備の省エネルギ対策が非常に重要となっており、併せて、省エネルギ対策の実践による農家経営の改善も必要に迫られている。
特許文献１には、ボイラの排熱と土壌に埋設したヒートパイプにより集熱した熱源により温室内を暖房し、土壌を熱源パイプにより加熱する農業用熱暖房装置について開示されている。
特開２００３−１８５３６８公報 A horticultural horticultural farmer can cultivate a wide variety of crops throughout the year by artificially creating an environment and temperature range most suitable for the crops using a greenhouse or heating equipment. However, the increase in production costs due to rising fuel prices has had a major impact on farm management. In addition, reducing greenhouse gas emissions as a measure to prevent global warming has become an important issue. For this reason, energy management measures for production management and production facilities are very important for institutional horticultural farmers, and it is also necessary to improve farm management by implementing energy conservation measures.

また、特許文献１に開示されている従来技術は、エネルギ源として石油が使われるため、上記従来の施設園芸と同様の課題を抱えている。また、ヒートパイプや熱源パイプを使用することにより、暖房効率を高めることはできるが、熱源パイプを土壌に直接埋設しているため、熱の伝達速度が遅いといった問題がある。
本発明は、かかる課題に鑑みてなされたものであり、土壌中に埋設した空気ダクト内に温度制御管を配設すると共に、空気ダクトに空気放出孔を設け、温度制御された空気ダクト内の空気を、空気放出孔を介して土壌中に放出することにより、土壌内への温度制御を容易とすると共に、省エネルギを実現した温室内温度制御装置を提供することを目的とする。 However, in conventional facility horticulture, oil heaters are generally used as a heating means in the winter season. However, the energy efficiency is low and not only enormous fuel costs are required, but also the problem of reducing greenhouse gas emissions. There is a problem that the degree of contribution is low.
Moreover, since the prior art currently disclosed by patent document 1 uses petroleum as an energy source, it has the subject similar to the said conventional horticulture. Moreover, although the heating efficiency can be increased by using a heat pipe or a heat source pipe, there is a problem that the heat transfer speed is slow because the heat source pipe is directly embedded in the soil.
The present invention has been made in view of such a problem, and a temperature control pipe is provided in an air duct embedded in soil, and an air discharge hole is provided in the air duct, so that the temperature in the air duct is controlled.

以下、本発明を図に示した実施形態を用いて詳細に説明する。但し、この実施形態に記載される構成要素、種類、組み合わせ、形状、その相対配置などは特定的な記載がない限り、この発明の範囲をそれのみに限定する主旨ではなく単なる説明例に過ぎない。
図１は本発明の第１の実施形態に係る温室内温度制御装置の構成を示す図である。図１（ａ）は側断面図、（ｂ）は上面図である。この温室内温度制御装置５０は、土壌上に立設されて内部空間を外気と遮蔽する温室８と、温室８内の空気温度及び温室８内の土壌温度を制御する温度制御設備５２と、を備えた温室内温度制御装置５０であって、温度制御設備５２は、吸気口と排気口を夫々温室８内に位置させた状態で土壌中に埋設された空気ダクト５と、空気ダクト５内に配設されて加熱、又は冷却用の流体を搬送することにより空気ダクト５内の空気を加熱又は冷却する温度制御管６と、空気ダクト５内に温室８内の空気を吸引する吸気ファン４と、空気ダクト５の排気口に設置され温度制御管６の隔壁を通じて空気ダクト５内の空気と温度制御管６内の流体間で熱の授受を行わせて加熱又は冷却を行なう熱交換器７と、熱交換器７と密着して設置され空気ダクト５内の空気を温室８内に排気する排気ファン９と、を備え、本実施形態では、夜間電力により水を加熱して給湯するヒートポンプ給湯器１の温水を貯湯槽２に貯留して、必要時に温度制御管６に貯湯槽２の温水を供給する。また、空気ダクト５に温度制御管６により加熱された空気を土壌１１中に放出する空気放出孔１２を備えている。また、本温室内温度制御装置５０をシステムとして稼働するために、温度センサ１０（上部温度センサ１０ａ、下部温度センサ１０ｂ、土壌温度センサ１０ｃ）を備えている。また、温室８内の空気を攪拌するための循環ファン３を備えても構わない。尚、図示は省略するが、熱交換器７により熱交換された温水は再び貯湯槽２に戻されて使用される。 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely illustrative examples and not intended to limit the scope of the present invention only unless otherwise specified. .
FIG. 1 is a diagram showing a configuration of a greenhouse temperature control apparatus according to the first embodiment of the present invention. FIG. 1A is a side sectional view, and FIG. 1B is a top view. The greenhouse temperature control device 50 includes a greenhouse 8 that stands on the soil and shields the internal space from the outside air, and a temperature control facility 52 that controls the air temperature in the greenhouse 8 and the soil temperature in the greenhouse 8. A temperature control device 50 provided in the greenhouse, the temperature control facility 52 includes an air duct 5 embedded in the soil with the air inlet and the air outlet located in the greenhouse 8, and the air duct 5. A temperature control pipe 6 that heats or cools the air in the air duct 5 by conveying a fluid for heating or cooling, and an intake fan 4 that sucks air in the greenhouse 8 into the air duct 5; A heat exchanger 7 installed at the exhaust port of the air duct 5 and performing heating or cooling by transferring heat between the air in the air duct 5 and the fluid in the temperature control pipe 6 through the partition wall of the temperature control pipe 6; The air duct 5 is installed in close contact with the heat exchanger 7 And an exhaust fan 9 that exhausts air into the greenhouse 8. In this embodiment, the hot water of the heat pump water heater 1 that supplies water by heating water with nighttime power is stored in the hot water tank 2, and temperature control is performed when necessary. Hot water from the hot water tank 2 is supplied to the pipe 6. In addition, the air duct 5 is provided with an air discharge hole 12 through which air heated by the temperature control pipe 6 is discharged into the soil 11. Moreover, in order to operate this greenhouse temperature control apparatus 50 as a system, the temperature sensor 10 (the upper temperature sensor 10a, the lower temperature sensor 10b, and the soil temperature sensor 10c) is provided. Moreover, you may provide the circulation fan 3 for stirring the air in the greenhouse 8. FIG. In addition, although illustration is abbreviate | omitted, the hot water heat-exchanged by the heat exchanger 7 is returned to the hot water tank 2 again, and is used.

次に本実施形態に係る温室内温度制御装置５０の概略動作について説明する。給湯器１は夜間電力を使用して水道水（或いは地下水）をヒートポンプ給湯器１により加熱して所定の温度（７０℃〜９０℃）に加熱して貯湯槽２に貯留する。貯湯槽２には図示を省略するが、温水を温度制御管６に流すポンプが備えられ、そのポンプの圧力により、温度制御管６内に温水を循環させる。また、温度制御管６は空気ダクト５内に配設されているので、温度制御管６の表面の熱により温められる。また、温室８内の空気を暖めるために、吸気ファン４と排気ファン９を同時に動作させる。これにより、空気ダクト５内の暖められた空気１３が空気放出孔１２を介して土壌１１に放出されと共に、熱交換器７により更に暖められて温室８内に排気される。この動作を繰り返すことにより、土壌１１と温室８内の空気が暖められる。また、暖められた空気は、温室８の上部に溜まるため、循環ファン３により空気を攪拌することにより、より全体の温度分布を均一化することができる。
図１（ｂ）では、温度制御管６を２本に分離して、それぞれに空気ダクト５、吸気ファン４、排気ファン９、及び熱交換器７を備えているが、空気ダクト５を連結して、吸気口と排気口にそれぞれ吸気ファン４、排気ファン９、及び熱交換器７を備える構成でも構わない。 Next, schematic operation of the greenhouse temperature control apparatus 50 according to the present embodiment will be described. The hot water heater 1 uses nighttime electric power to heat tap water (or groundwater) with the heat pump water heater 1, heat it to a predetermined temperature (70 ° C. to 90 ° C.), and store it in the hot water tank 2. Although not shown in the figure, the hot water tank 2 is provided with a pump for flowing hot water to the temperature control pipe 6, and the hot water is circulated in the temperature control pipe 6 by the pressure of the pump. Further, since the temperature control pipe 6 is disposed in the air duct 5, it is heated by the heat of the surface of the temperature control pipe 6. In order to warm the air in the greenhouse 8, the intake fan 4 and the exhaust fan 9 are operated simultaneously. As a result, the heated air 13 in the air duct 5 is released to the soil 11 through the air discharge holes 12, and is further heated by the heat exchanger 7 and exhausted into the greenhouse 8. By repeating this operation, the air in the soil 11 and the greenhouse 8 is warmed. Moreover, since the warmed air accumulates in the upper part of the greenhouse 8, by stirring the air with the circulation fan 3, the entire temperature distribution can be made more uniform.
In FIG. 1 (b), the temperature control pipe 6 is divided into two, and each is provided with an air duct 5, an intake fan 4, an exhaust fan 9, and a heat exchanger 7. Thus, a configuration in which the intake fan 4, the exhaust fan 9, and the heat exchanger 7 are provided in the intake port and the exhaust port, respectively, may be used.

本発明の最も大きな特徴は、空気ダクト５内に温度制御管６を配設すると共に、空気ダクト５に温度制御管６により加熱された空気を土壌１１内に放出する空気放出孔１２を備えた点である。そして、温度制御管６から放出される温度により加熱された空気を排気ファン９により排気し、温室８内を循環して吸気ファン４により再び空気ダクト５に流入させる。このとき、吸気ファン４により吸入された空気は圧力が高いため、空気放出孔１２から土壌１１に放出される。これにより、土壌１１への熱伝達を早めて、且つ均一に伝達させることができる。   The most significant feature of the present invention is that a temperature control pipe 6 is disposed in the air duct 5 and an air discharge hole 12 is provided in the air duct 5 for discharging air heated by the temperature control pipe 6 into the soil 11. Is a point. Then, air heated by the temperature discharged from the temperature control pipe 6 is exhausted by the exhaust fan 9, circulated in the greenhouse 8, and again flows into the air duct 5 by the intake fan 4. At this time, since the air sucked by the intake fan 4 has a high pressure, it is discharged from the air discharge hole 12 to the soil 11. Thereby, heat transfer to the soil 11 can be accelerated and transmitted uniformly.

図２は本発明の第２の実施形態に係る温室内温度制御装置の構成を示す図である。同じ構成要素には図１と同じ参照番号を付して説明する。図２が図１と異なる点は、貯湯槽２と温度制御管６との間に、温水又は冷却水の何れかを選択的に切り替えて温度制御管６に流入させる切替器１４を備えたことである。切替器１４には、配管１５を介して地下水１６を汲み上げて温度制御管６に供給する図示しないポンプが備えられている。
即ち、空気ダクト５には空気が流れているため、温度制御管６の表面温度が空気に伝達して加熱又は冷却する。従って、温度制御管６の温度により空気の温度が左右される。本実施形態では、温水又は冷却水の何れかを選択的に切り替えて温度制御管６に流入させる切替器１４を備え、温室８の温度を上昇させるときは温水を流し、温室８の温度を低下させるときは冷却水を流すように作動させる。これにより、温室８の温度を広い範囲で制御することができる。 FIG. 2 is a diagram showing a configuration of a greenhouse temperature control apparatus according to the second embodiment of the present invention. The same components will be described with the same reference numerals as in FIG. 2 differs from FIG. 1 in that a switch 14 is provided between the hot water tank 2 and the temperature control pipe 6 to selectively switch either hot water or cooling water into the temperature control pipe 6. It is. The switch 14 is provided with a pump (not shown) that draws groundwater 16 through the pipe 15 and supplies it to the temperature control pipe 6.
That is, since air flows through the air duct 5, the surface temperature of the temperature control pipe 6 is transmitted to the air to be heated or cooled. Accordingly, the temperature of the air depends on the temperature of the temperature control pipe 6. In this embodiment, the switch 14 which selectively switches either warm water or cooling water and flows into the temperature control pipe 6 is provided. When the temperature of the greenhouse 8 is raised, warm water is flowed and the temperature of the greenhouse 8 is lowered. Operate the cooling water to flow. Thereby, the temperature of the greenhouse 8 can be controlled in a wide range.

図３は空気放出孔１２を開放又は閉止する放出孔開閉器（放出孔開閉手段）５３の一例を示す図である。図３（ａ）は断面図、図３（ｂ）は開閉動作を説明する図である。図３（ａ）のように、放出孔開閉器５３は、空気ダクト５に設けられた空気放出孔１２に取り付けられ、枠体２０と枠体２０内を回転する回転板２７と回転板２７を回転させるソレノイド２３から構成されている。回転板２７は軸２１によりソレノイド２３の軸２２に回動可能に取り付けられている。図３（ｂ）を参照して放出孔開閉器５３の概略動作について説明する。図３（ｂ）はソレノイド２３を動作させて放出孔開閉器５３を閉止した状態を示す図である。この状態では、枠体２０の開口部２４と回転板２７の開口部２５は位置が一致しないため、回転体２７により枠体２０の開口部２４は閉止されている。次に、ソレノイド２３の動作を停止すると、バネ２６の力で矢印Ｂの方向に軸２２が移動し、その結果、回転板２７の軸２１が回転して回転板２７が矢印Ａの方向に回転することにより、回転板２７の開口部２５と枠体２０の開口部２４が一致して放出孔開閉器５３を開放状態にする。
即ち、温室８では畝ごとに異なる作物を栽培することがある。作物は種類により土壌温度が同じとは限らない。そこで本発明では、空気放出孔１２を開放又は閉止する放出孔開閉器５３を備え、土壌１１の温度を畝ごとに制御する。これにより、作物ごと、或いは畝ごとに土壌温度をきめ細かく制御することができる。 FIG. 3 is a view showing an example of a discharge hole switch (discharge hole opening / closing means) 53 that opens or closes the air discharge hole 12. FIG. 3A is a cross-sectional view, and FIG. 3B is a diagram for explaining an opening / closing operation. As shown in FIG. 3A, the discharge hole switch 53 is attached to the air discharge hole 12 provided in the air duct 5, and includes the frame body 20, the rotating plate 27 that rotates in the frame body 20, and the rotating plate 27. The solenoid 23 is rotated. The rotating plate 27 is rotatably attached to the shaft 22 of the solenoid 23 by the shaft 21. The general operation of the discharge hole switch 53 will be described with reference to FIG. FIG. 3B is a diagram showing a state in which the solenoid 23 is operated to close the discharge hole switch 53. In this state, the opening 24 of the frame 20 and the opening 25 of the rotating plate 27 do not coincide with each other, and therefore the opening 24 of the frame 20 is closed by the rotating body 27. Next, when the operation of the solenoid 23 is stopped, the shaft 22 is moved in the direction of the arrow B by the force of the spring 26. As a result, the shaft 21 of the rotating plate 27 is rotated and the rotating plate 27 is rotated in the direction of the arrow A. As a result, the opening 25 of the rotating plate 27 and the opening 24 of the frame 20 are aligned to open the discharge hole switch 53.
That is, in the greenhouse 8, different crops may be cultivated for each basket. Depending on the type of crop, the soil temperature is not always the same. Therefore, in the present invention, a discharge hole switch 53 that opens or closes the air discharge hole 12 is provided, and the temperature of the soil 11 is controlled for each basket. Thereby, the soil temperature can be finely controlled for each crop or for each basket.

図４は本発明に係る温室内温度制御システムの構成を示すブロック図である。この温室内温度制御システム６０は、温室８内の空気温度を検出する上部温度センサ１０ａ、下部温度センサ１０ｂと、土壌温度を検出する土壌温度センサ１０ｃと、各温度センサにより検出された温度に基づいて図１又は図２に記載の温室内温度制御装置５０、５１に係る吸気ファン４、排気ファン９、及び放出孔開閉器５３を制御する制御部３０と、を備えて構成されている。尚、切替器は制御部３０を介して動作させてもよいし、制御部３０を介さずに手動にて動作させても構わない。
即ち、温室内温度制御設備５０、５１を制御するためには、温室８内と土壌１１の温度を検知する温度センサ１０（１０ａ〜１０ｃ）が必要である。これらの温度センサからの情報は制御部３０に入力され、制御部３０は各温度情報に基づいて吸気ファン４、排気ファン９、又は放出孔開閉器５３に係る動作を制御する。ここでいう動作とは、ファンの回転又は停止や放出孔開閉器５３の開閉動作をいう。これにより、温室全体の温度管理をシステムとして自動管理することができる。 FIG. 4 is a block diagram showing the configuration of the greenhouse temperature control system according to the present invention. The greenhouse temperature control system 60 is based on an upper temperature sensor 10a and a lower temperature sensor 10b that detect an air temperature in the greenhouse 8, a soil temperature sensor 10c that detects a soil temperature, and a temperature detected by each temperature sensor. 1 or 2, the control unit 30 that controls the intake fan 4, the exhaust fan 9, and the discharge hole switch 53 according to the greenhouse temperature control devices 50 and 51 shown in FIG. 1 or 2 is configured. The switch may be operated via the control unit 30 or may be manually operated without the control unit 30.
That is, in order to control the temperature control facilities 50 and 51 in the greenhouse, the temperature sensors 10 (10a to 10c) that detect the temperatures of the greenhouse 8 and the soil 11 are necessary. Information from these temperature sensors is input to the control unit 30, and the control unit 30 controls the operation related to the intake fan 4, the exhaust fan 9, or the discharge hole switch 53 based on each temperature information. The operation here refers to the rotation or stop of the fan or the opening / closing operation of the discharge hole switch 53. Thereby, the temperature management of the whole greenhouse can be automatically managed as a system.

In order to use nighttime electric power, when it becomes the time zone (YES in S1), the water heater 1 operates to heat tap water or groundwater (S2). The heated hot water is stored by the hot water storage device 2 and stored until the hot water storage device 2 is full (S3). When the water heater 2 is full (YES in S3), the water heater 1 is stopped (S4). At this time, hot water of 70 ° C. to 90 ° C. is stored in the hot water storage device 2. Next, when the water heater 2 is full, hot water supply to the temperature control pipe 6 is started (S5). Thereafter, the control unit 30 detects temperature information of the upper temperature sensor 10a and the lower temperature sensor 10b and verifies whether or not the temperature reaches a predetermined value (S6). If the predetermined temperature has not been reached (NO in S6), the intake fan 4 and the exhaust fan 9 are operated (S7). Thereby, warm air is circulated in the greenhouse 8. On the other hand, if the predetermined temperature has been reached in step S6 (YES in S6), the exhaust fan 9 is stopped and the supply of warm air to the greenhouse 8 is stopped (S10). Next, the temperature information of the soil temperature sensor 10c is detected and it is verified whether or not the temperature reaches a predetermined value (S8). If not reached (NO in S8), the process returns to step S5. If the predetermined value has been reached in step S8 (YES in S9), the intake fan 4 is stopped and the pressure at which the warm air is discharged into the soil 11 is reduced (S9).

In order to use nighttime electric power, when it is the time zone (YES in S20), the water heater 1 operates to heat tap water or groundwater (S21). The heated hot water is stored by the hot water storage device 2 and stored until the hot water storage device 2 is full (S22). When the water heater 2 is full (YES at S22), the water heater 1 is stopped (S23). At this time, hot water of 70 ° C. to 90 ° C. is stored in the hot water storage device 2. Next, when the water heater 2 is full, hot water supply to the temperature control pipe 6 is started (S24). Thereafter, the control unit 30 detects temperature information of the upper temperature sensor 10a and the lower temperature sensor 10b and verifies whether or not the temperature reaches a predetermined value (S25). If the predetermined temperature has not been reached (NO in S25), the intake fan 4 and the exhaust fan 9 are operated (S26). Thereby, warm air is circulated in the greenhouse 8. On the other hand, if the predetermined temperature has been reached in step S25 (YES in S25), the exhaust fan 9 is stopped and the blowing of warm air to the greenhouse 8 is stopped (S29). Next, the temperature information of the soil temperature sensor 10c is detected, and it is verified whether or not the temperature reaches a predetermined value (S27). If not reached (NO in S27), the process returns to step S24. If the predetermined value is reached in step S27 (YES in S27), the discharge hole switch 53 is operated to close the air discharge hole 12 and stop the air discharged into the soil 11 (S28).

図７は図６のフローチャートを更に詳細に説明するための説明図である。一般的には、温室では、各種の作物を畝毎に分けて栽培する場合がある。そのとき、作物によって土壌温度が異なる場合がある。そこで各畝に空気ダクト５ａ〜５ｄを配設し、夫々の畝に土壌温度センサ１０ｃを夫々配設する。当然、どの土壌温度センサがどの畝の土壌温度を検知するかは予め決定しておく。また、各畝に配設された空気ダクトにある空気放出孔１２に夫々放出孔開閉器５３を配置する。この放出孔開閉器５３も、当然どの放出孔開閉器５３がどの畝の空気ダクトに配置したかを予め決定しておく。また、放出孔開閉器５３ごとに制御してもよいし、畝ごとに放出孔開閉器５３を制御しても構わない。このように構成しておくことにより、図６のステップＳ２８で空気放出孔を閉止する場合に、制御部３０は各畝毎に最適な温度を土壌温度センサにより検知して、その温度情報に基づいて畝ごとの放出孔開閉器をきめ細かく制御することができる。   FIG. 7 is an explanatory diagram for explaining the flowchart of FIG. 6 in more detail. Generally, in a greenhouse, various crops may be cultivated separately for each basket. At that time, the soil temperature may differ depending on the crop.
