Description

本発明は、農業用ハウスの温度調整システムに係り、特に、被覆フィルムを内外アーチ状に二重張りした農業用ハウスの温度調整システムに関する。   The present invention relates to a temperature control system for an agricultural house, and more particularly, to a temperature control system for an agricultural house in which a covering film is doubled in an inner and outer arch shape.

従来、いわゆるビニールハウスあるいは農業用ハウスと呼ばれる植物栽培用建物が知られており、温湿度を含む空調管理の下で例えば、野菜、果物、花等が育成される。農業用ハウスは、一般的には木材又は鋼材を躯体とし、合成樹脂のフィルムで外壁を被覆した農業用の小屋であり、被覆材料には、農業用ポリ塩化ビニルフィルム（農ビ）が使われることが多い。さらに、農業用ハウスの躯体として、あらかじめ湾曲させたパイプや鋼材を組み付けてアーチを構成し、このアーチを奥行き方向に延長したものが基本的な骨組みとなり、必要に応じて筋交いなどで補強されたものが知られている。近時、アーチ状の被覆フィルムの内側に間隔をあけて小型の被覆フィルムを設置した二重張り構造の農業用ハウスが公知であり、内外被覆フィルムの間隙の空気層を断熱層として外部の気候変動を緩衝しつつ内側の被覆フィルム内のかまぼこ状空間をハウス内空間として植物育成を行なわせるものが普及しつつある。二重張り構造の農業用ハウスは断熱層空間と保温空間とで冬季や寒冷時等での高い保温機能を有する点で優れる一方、夏季、高温時等では図１０に示すように内側フィルム９１の頂部付近やその周辺、断熱層空間９６での外側フィルム９２の頂部内側付近からその周辺部分では、加温あるいは加熱された空気の熱溜まり９３が生じ、排気されることなく滞留するために夏季高温時等ではハウス内が異常高温となり、育成植物に深刻なダメージを与えるおそれがあった。特に、二重張り構造の農業用ハウスでは、内側フィルムについてはフィルム開閉装置によるある程度大きな開口となる開閉範囲Ｊ−Ｊを確保できるものの、外側フィルムについては強風、突風、台風等の被害に耐える強度保持や降雨時の短時閉鎖復帰のために開閉範囲Ｋ−Ｋを狭くせざるを得ず、このため、断熱層に広範囲の熱だまりが生じ、さらにこのために内側フィルム内空間においても広がりのある熱溜まり域が生じ、冷房効率を著しく低下させたり、あるいは育成植物そのものに被害を生じさせる問題があった。さらには、近時の地球温暖化傾向が強まるなか、ハウス内の熱溜まり解消は早期の対応が望まれる問題であった。従来、二重張り構造の農業用ハウスについて特許文献１の提案がなされている。   Conventionally, a plant cultivation building called a so-called vinyl house or agricultural house is known, and vegetables, fruits, flowers, and the like are grown under air conditioning management including temperature and humidity. Agricultural houses are generally agricultural huts that are made of wood or steel and whose outer walls are covered with a synthetic resin film. Agricultural polyvinyl chloride film (agricultural bi) is used as the covering material. There are many cases. In addition, as the housing of an agricultural house, an arch is constructed by assembling pre-curved pipes and steel materials, and this arch is extended in the depth direction to form a basic framework, which is reinforced by bracing as necessary. Things are known. Recently, an agricultural house with a double tension structure in which a small covering film is installed inside an arched covering film with a space between them is known, and an external climate is formed using an air layer in the gap between the inner and outer covering films as a heat insulating layer. The thing which makes a plant upbringing by making the kamaboko-shaped space in an inner coating film into a space in a house while buffering a fluctuation is spreading. The double-stretched agricultural house is superior in that it has a high heat-retaining function in the winter and in cold weather, etc. in the heat insulation layer space and the heat insulation space, while in the summer and high temperatures, the inner film 91 is formed as shown in FIG. In the vicinity of the top and the periphery thereof, and in the vicinity of the top portion of the outer film 92 in the heat insulating layer space 96 from the vicinity thereof, a heat pool 93 of heated or heated air is generated and stays without being exhausted. At times, the inside of the house became extremely hot and could cause serious damage to the growing plant. In particular, in an agricultural house with a double-tension structure, the inner film can secure an opening / closing range JJ, which is a somewhat large opening by a film opening / closing device, but the outer film has strength to withstand damage from strong winds, gusts, typhoons, etc. The opening and closing range KK must be narrowed for holding and returning to the closed state in the event of rain, and this causes a wide range of heat accumulation in the heat insulating layer, which further spreads in the inner film space. There was a problem that a certain heat storage area was generated, and the cooling efficiency was remarkably lowered, or the growing plant itself was damaged. Furthermore, with the recent trend of global warming becoming stronger, the elimination of heat accumulation in the house has been a problem that requires an early response. Conventionally, the proposal of patent document 1 is made | formed about the agricultural house of a double tension structure.

実開昭６１−７４３５５号公報Japanese Utility Model Publication No. 61-74355

特許文献１は内外二重壁のビニールハウスの断熱構造について、二重壁間に温風を流通させて断熱気膜を構成するものが開示されているが、この構造においても内壁の内側の熱だまりは解消できないばかりか、ビニールフィルムの一部を開閉させる開閉装置の設置もないために、植物育成空間の内壁の内側空間内が異常高温となり良好な植物育成環境を提供することは困難であった。   Patent Document 1 discloses a heat insulation structure of an inner / outer double wall greenhouse that circulates warm air between the double walls to form a heat insulating air film. In this structure as well, heat inside the inner wall is disclosed. Not only can the stagnation be eliminated, but there is no installation of an open / close device that opens and closes a part of the vinyl film, so it is difficult to provide a good plant growth environment because the inside space of the inner wall of the plant growth space becomes abnormally hot. It was.

本発明は上記従来の課題に鑑みてなされたものであり、その一つの目的は、二重張り農業用ハウスについて、ハウス内空気を直接に外被体の外部に排気させることによりハウス内の天井部分の温熱溜まりを短時間で解消し、ハウス内空調効率の向上と異常高温時の保護を行なえる農業用ハウスの温度調整システムを提供することにある。また、本発明の他の目的は、熱溜まりの直接排気機能に加えて内被体の内側の天井部分に滞留しやすい加温空気を地面側に供給して冬季や寒冷時の加温効率を向上させ得る農業用ハウスの温度調整システムを提供することにある。   The present invention has been made in view of the above-described conventional problems, and one object of the present invention is a ceiling in a house for a double-tensioned agricultural house by exhausting the air in the house directly to the outside of the casing. An object of the present invention is to provide a temperature control system for an agricultural house that can eliminate heat accumulation in a part in a short time, improve the air conditioning efficiency in the house, and protect at an abnormally high temperature. In addition to the direct exhaust function of the heat reservoir, another object of the present invention is to supply warming air that tends to stay on the inner ceiling of the inner cover to the ground side to improve the heating efficiency in winter and cold. An object is to provide a temperature control system for an agricultural house that can be improved.

上記課題を解決するために本発明は、間隔Ｈを開けて内被体１０と外被体１２とをアーチ状に二重に張設した二重張り農業用ハウスの温度調整システムであり、内被体１０の一部を開閉する内被開閉装置１４と、外被体１２の一部を開閉する外被開閉装置１６と、を有し、内外被体１０，１２のそれぞれの一部の開閉を行ないつつ必要に応じて内被体１０内の空気であって内外被体１０，１２を法線Ｎ方向貫通状に直通排気させる直通排気手段（８）を有することを特徴とする農業用ハウスの温度調整システムから構成される。二重張り農業用ハウスの本体構造は種々の形態があり得る。外形形状は完全な円弧形状でなく、山形形状のものも含む。また、内外の被覆体の形状は一方が山形で他方がアーチ形状などの組み合わせとしてもよい。本発明の農業用ハウスの温度調整システムは、それを構成する要素の性質から農業用ハウスの温度調整装置としても構成し得る。   In order to solve the above-mentioned problems, the present invention is a temperature control system for a double-tensioned agricultural house in which an inner covering 10 and an outer covering 12 are doubled in an arch shape with an interval H. An inner cover opening / closing device 14 for opening and closing a part of the body 10 and an outer cover opening / closing device 16 for opening and closing a part of the outer body 12, and opening and closing each of the inner and outer bodies 10 and 12. Agricultural house characterized by having direct exhaust means (8) for directly exhausting the inner and outer coverings 10 and 12 in a normal N-direction through manner while performing It consists of a temperature control system. The body structure of a double-tensioned agricultural house can take various forms. The outer shape is not a complete arc shape, but includes a mountain shape. Moreover, the shape of the inner and outer coverings may be a combination such that one is a mountain and the other is an arch. The temperature control system for an agricultural house according to the present invention can also be configured as a temperature control device for an agricultural house due to the nature of the constituent elements.

その際、直通排気手段（８）は、内被体１０の内側に設けられ内被体アーチ面の法線Ｎ方向に向けて空気を吹き出す送風機４２と、外被体１２の固定被い部１２２に取り付けられ送風機４２からの風を通過させる天窓開口６２を開閉する天窓開口開閉装置６０と、を含むとよい。天窓開口開閉装置６０は断熱空間により離隔配置された送風機の風を効率よく受け得る位置に位置合わせされて設置されるとよく、例えば円形の送風機からの流路を設定するとその中心線上に天窓開口開閉装置６０側の例えば円形流路の中心が位置するように設置されるのが理想的である。しかし、ある程度それらの中心からそれた位置であっても直接に送風機からの風を受けて通過させ外部に直通排気させうる位置であればよい。天窓開口開閉装置は外被体に形成した天窓開口を開閉する機能を有すればよいが、降雨時の断熱空間側への降り込みを防止するためには開口より広い蓋部材を有し、開口に対して法線方向（上下方向）に移動しつつ開閉する構造であるのが好ましい。送風機はその設置場所周辺の空気を吸い込んで一方向に吹き出させる指向性のある構造の送風機であるとよい。送風機による風速、風量は大きいほうが内被体内の温熱空気の直通排気機能に資するが、すくなくとも送風機からの風が断熱空間を経由して直接に天窓開口開閉装置６０から排気される機能を有すればよい。   At that time, the direct exhaust means (8) is provided on the inner side of the inner covering 10 and blows air toward the normal N direction of the inner covering arch surface, and the fixed covering portion 122 of the outer covering 12. And a skylight opening opening / closing device 60 that opens and closes the skylight opening 62 that allows the wind from the blower 42 to pass therethrough. The skylight opening opening / closing device 60 is preferably positioned and installed at a position where it can efficiently receive the wind of the blower spaced apart by the heat insulation space. For example, when a flow path from a circular blower is set, the skylight opening is opened on the center line. Ideally, it is installed such that the center of, for example, a circular channel on the switchgear 60 side is located. However, even if it is a position deviated from the center to some extent, it may be a position where it can directly receive and pass the wind from the blower and exhaust it directly to the outside. The skylight opening / closing device only needs to have a function of opening / closing the skylight opening formed in the outer casing, but in order to prevent the entry into the heat insulation space side during rain, it has a lid member wider than the opening, On the other hand, it is preferable to open and close the structure while moving in the normal direction (vertical direction). The blower may be a blower having a directivity structure that sucks air around the installation location and blows it out in one direction. The larger the wind speed and air volume of the blower contributes to the direct exhaust function of the hot air in the inner casing, but at least the wind from the blower has the function of exhausting directly from the skylight opening / closing device 60 through the heat insulation space. Good.

また、送風機４２と天窓開口開閉装置６０はそれぞれ内外被体１０，１２のアーチ頂部又はアーチ頂部近傍に設置されているとよく、それぞれの被覆部材の内側天井部分において滞留して高温化した空気を直接に外部に排気させることができ、ハウス内の天井部分の温熱溜まりを短時間で解消し、異常高温時の保護を確実に行なえる。   Also, the blower 42 and the skylight opening / closing device 60 are preferably installed at the arch tops of the inner and outer coverings 10 and 12 or in the vicinity of the arch tops, respectively, so that the air staying at the inner ceiling portions of the respective covering members is heated. It can be exhausted directly to the outside, eliminating the heat accumulation on the ceiling in the house in a short time and ensuring protection at abnormally high temperatures.

また、送風機４２は、円筒ケース４６と円筒ケース内に回転羽根４８を設け天窓開口開閉装置６０の流路６１開口に向けて直接に風を送風させる指向形軸流ファンからなるとよい。遠心ファンを用いることもできるが、指向形軸流ファンとすることで、簡単な構造でしかも軽負荷であり同時に指向性のある風を吹き出させる機能を行える。   The blower 42 may be a cylindrical case 46 and a directional axial fan that is provided with a rotating blade 48 in the cylindrical case and directly blows air toward the opening of the channel 61 of the skylight opening / closing device 60. A centrifugal fan can also be used, but by using a directional axial flow fan, it is possible to perform a function of blowing a directional wind with a simple structure and a light load at the same time.

また、内外被体１０，１２の法線Ｎ方向に見て送風機４２のケース４６円形と天窓開口６２とが少なくとも一部で重複するように送風機４２と天窓開口開閉装置６０とが位置を決められて取り付けられているとよい。   Further, the blower 42 and the skylight opening opening / closing device 60 are positioned so that the circular case 46 of the blower 42 and the skylight opening 62 overlap at least partially when viewed in the normal N direction of the inner and outer jackets 10 and 12. It is good to be attached.

また、天窓開口開閉装置６０は、法線Ｎ方向に沿って上下動方向に移動し上から覆蓋状に流路６１開口を開閉する蓋部材６８を有するとよく、雨よけと共に内被体側からの直通排気機能を同時に行える。   Further, the skylight opening opening / closing device 60 may include a lid member 68 that moves in the vertical movement direction along the normal N direction and opens and closes the opening of the flow path 61 in the shape of a cover from above. The exhaust function can be performed simultaneously.

また、送風機４２は、正逆回転式送風機からなり、外向き法線方向に風を吹き出して天窓開口開閉装置６０の天窓開口６２から直接に内被体１０内側の高ハウス内温度空気を外部に排気する状態と、内向き法線方向に風を吹き出して地面側に向けて流す状態と、に選択駆動させるとなおよい。   The blower 42 is composed of a forward / reverse rotating blower, blows air in the outward normal direction, and directs the high-house temperature air inside the inner casing 10 directly from the skylight opening 62 of the skylight opening opening / closing device 60 to the outside. It is more preferable to selectively drive the exhaust state and the state in which the wind is blown in the inward normal direction to flow toward the ground side.

本発明の農業用ハウスの温度調整システムによれば、間隔を開けて内被体と外被体とをアーチ状に二重に張設した二重張り農業用ハウスの温度調整システムであり、内被体の一部を開閉する内被開閉装置と、外被体の一部を開閉する外被開閉装置と、を有し、内外被体のそれぞれの一部の開閉を行ないつつ必要に応じて内被体内の空気であって内外被体を法線方向貫通状に直通排気させる直通排気手段を有する構成であるから、内外二重張り農業用ハウスの内側のハウス内空気を直接に外被体の外部に排気させる結果、ハウス内の天井部分の温熱溜まりを短時間で解消し、ハウス内空調効率を向上させることができる。また、ハウス内の高温域の空気を直接に外部排気できるから、急激なハウス内温度上昇による異常高温化を防止し、育成植物の保護を図ることができる。   According to the temperature control system for an agricultural house of the present invention, there is provided a temperature control system for a double-tensioned agricultural house in which an inner covering and an outer covering are doubled in an arch shape at an interval, An inner cover opening and closing device that opens and closes a part of the body, and an outer cover opening and closing device that opens and closes a part of the outer body, and opens and closes each part of the inner and outer covers as needed. Since it is configured to have direct exhaust means for exhausting the inner and outer casings directly through the normal direction so as to pass through the inner casing, the inner casing air directly inside the inner and outer double-tensioned agricultural house As a result of exhausting to the outside, the heat accumulation in the ceiling portion in the house can be eliminated in a short time, and the air conditioning efficiency in the house can be improved. Moreover, since the air in the high temperature region in the house can be directly exhausted to the outside, an abnormally high temperature due to a sudden rise in the temperature in the house can be prevented, and the growing plant can be protected.

また、直通排気手段は、内被体の内側に設けられ内被体アーチ面の法線方向に向けて空気を吹き出す送風機と、外被体の固定被い部に取り付けられ送風機からの風を通過させる天窓開口を開閉する天窓開口開閉装置と、を含む構成とすることにより、内外二重張り被覆フィルムタイプの農業用ハウスについて内被体内側の温熱空気の直接排気をそれぞれの内外被開閉装置による内外被体の開閉を行いつつ具体的に実現することができる。また、ハウス内温熱空気の吸入吹き出し側と外部空間への排気側とでそれぞれに機能を行う装置を２個設置し、断熱空間を介して空間連結させることで、装置の小型、軽量化、低コスト化を図れ農業用ハウスの屋根部分に具体的に搭載設置することができる。さらに、天窓開口開閉装置による外部への排気時に断熱空間内の滞留温熱空気も巻き込んで同時に排気するから、ハウス内温度全体の換気を短時間で高効率に行える。   Further, the direct exhaust means is provided on the inner side of the inner casing and blows air toward the normal direction of the inner casing arch surface, and is attached to the fixed covering portion of the outer casing and passes the wind from the fan. And a skylight opening opening / closing device that opens and closes the skylight opening to allow direct exhaust of the hot air inside the inner casing for each of the inner and outer double-tensioned covering film type agricultural houses by each inner / outer opening / closing device This can be specifically realized while opening and closing the inner and outer casings. In addition, by installing two devices that perform functions on the intake / outlet side of the hot air in the house and on the exhaust side to the external space, and connecting them through a heat-insulating space, the device can be reduced in size, weight, and The cost can be reduced, and it can be installed on the roof of an agricultural house. Furthermore, since the hot air staying in the heat insulation space is also entrapped and exhausted at the time of exhausting to the outside by the skylight opening / closing device, the entire house temperature can be ventilated with high efficiency in a short time.

また、送風機と天窓開口開閉装置はそれぞれ内外被体のアーチ頂部又はアーチ頂部近傍に設置された構成とすることにより、内被体の内側並びに断熱空間においてそれぞれの天井部分に近い部分で滞留しやすい高温空気やそれらの周辺空気を効率よく直通排気させ得る。   Further, the blower and the skylight opening / closing device are each installed at the arch top of the inner / outer casing or in the vicinity of the arch apex, so that it is easy to stay inside the inner casing and in a portion near the ceiling in the heat insulating space. High-temperature air and surrounding air can be efficiently exhausted directly.

また、送風機は、円筒ケースと円筒ケース内に回転羽根を設け天窓開口開閉装置の流路開口に向けて直接に風を送風させる指向形軸流ファンからなる構成であるから、簡単な構造でしかも軽負荷であり同時に天窓開口開閉装置に向けて直接に送風させ指向性のある風を吹き出させることが可能である。   In addition, the blower has a simple structure because it is composed of a cylindrical case and a directional axial fan in which rotating blades are provided in the cylindrical case and air is blown directly toward the channel opening of the skylight opening / closing device. It is a light load, and at the same time, it is possible to blow directly toward the skylight opening / closing device to blow out directional wind.

また、内外被体の法線方向に見て送風機のケース円形と天窓開口とが少なくとも一部で重複するように送風機と天窓開口開閉装置とが位置を決められて取り付けられた構成とすることにより、内被体の内側の送風機から離隔して配置された天窓開口開閉装置に向けて内被体内あるいは断熱空気層の温熱空気を確実に送風させることができる。   In addition, by adopting a configuration in which the blower and the skylight opening opening / closing device are positioned and attached so that the case circular shape of the blower and the skylight opening overlap at least partially when viewed in the normal direction of the inner and outer covers The hot air in the inner casing or the heat insulating air layer can be surely blown toward the skylight opening / closing device arranged away from the blower inside the inner casing.

また、天窓開口開閉装置は、法線方向に沿って上下動方向に移動し上から覆蓋状に流路開口を開閉する蓋部材を有する構成であるから、通常は上下方向に落下する雨の雨よけと共に内被体側からの指向性を有する温熱空気直通排気機能を同時に行える。   Further, the skylight opening / closing device has a cover member that moves in the vertical movement direction along the normal direction and opens and closes the channel opening in a cover-like shape from above. At the same time, the hot air direct exhaust function having directivity from the inner body side can be performed simultaneously.

また、送風機４２は、正逆回転式送風機からなり、外向き法線方向に風を吹き出して天窓開口開閉装置６０の天窓開口６２から直接に内被体１０内側の高ハウス内温度空気を外部に排気する状態と、内向き法線方向に風を吹き出して地面側に向けて流す状態と、に選択駆動させる構成であるから、内外二重張り農業用ハウスの内側のハウス内空気を直接に外被体の外部に排気させる機能とともに、夜間や冬季において大気気温の低下時に積極的にハウス内空間の暖房を行う必要がある場合や、保温機能の強化を行う場合に微風暖気運転と対流によるハウス内全体の保温機能強化を図ることができる。   The blower 42 is composed of a forward / reverse rotating blower, blows air in the outward normal direction, and directs the high-house temperature air inside the inner casing 10 directly from the skylight opening 62 of the skylight opening opening / closing device 60 to the outside. Since it is configured to selectively drive between the exhaust state and the state where the wind is blown out in the direction of the inward normal and flows toward the ground side, the air inside the house inside and outside the double-tensioned agricultural house is directly removed. In addition to the function of exhausting outside the body, it is necessary to actively heat the space in the house at night or in the winter when the air temperature drops, or when the warming function is strengthened, the house is made by light wind warm-up operation and convection It is possible to enhance the heat insulation function of the whole.

本実施形態において、一つの特徴的なことは、内外二重張り農業用ハウスにおいて、必要に応じて内被体の内部、つまり、ハウス内空間３００の頂部近傍の内被体壁面近傍に分布する熱溜り空気を直接に外部に直通排気させる直通排気手段を設けたことである。すなわち、図１ないし図３において、内被体１０の内側と外被体１２とには中間の断熱層空間により連結された直通排気装置８が設けられている。直通排気装置８は、内外被体１０，１２のそれぞれの一部の開閉を行ないつつ必要に応じて内被体１０内の空気であって内外被体１０，１２を法線方向貫通状に直通排気させる直通排気手段であり、内被体１０の内側に設置されて排風機能を行う第１装置と、外被体に貫通状に設置されて外被体の天窓開口を開閉する機能を行う第２装置と、を有し、これらは中間の断熱空間を介して空気的に連結されている。すなわち、第１装置の排風駆動による空気流が直接に第２装置の天窓開口に到達し通過して外部に排出される位置にこれら第１、第２装置が設置される。   In the present embodiment, one characteristic feature is that the inner and outer double-stretched agricultural houses are distributed inside the inner covering as needed, that is, in the vicinity of the inner covering wall surface near the top of the inner space 300 of the house. A direct exhaust means for directly exhausting the heat accumulation air directly to the outside is provided. That is, in FIGS. 1 to 3, a direct exhaust device 8 connected by an intermediate heat insulating layer space is provided on the inner side of the inner casing 10 and the outer casing 12. The direct exhaust device 8 opens and closes a part of each of the inner and outer casings 10 and 12 and directly passes the inner and outer casings 10 and 12 in a normal direction through the air inside the inner casing 10 as necessary.

A second device, which are connected pneumatically via an intermediate insulating space. That is, the first and second devices are installed at a position where the airflow generated by the exhausting drive of the first device reaches the skylight opening of the second device, passes through, and is discharged to the outside.

本実施形態において、直通排気装置８の第１装置は、送風機４２で構成されるとともに、第２装置は、天窓開口開閉装置６０から構成されている。送風機４２は、内被体１０の内側に設けられ内被体のアーチ面ないしは円弧面の法線方向に向けてハウス内空間３００の空気を吹き出すハウス内空気の排気駆動手段であり、実施形態において、内被体１０のアーチ頂部又はその近傍に設置されてハウス内空間で最も高温域となる部分近くの空気を直接に排気させる。図１において、送風機４２は、複数のアーチ部材２４のいくつかに例えばワイヤなどの吊支部材４４に吊支されて本体が内被体１０の内側空間内に設置されている。本実施形態において、送風機４２は、内外被体の法線方向に向けて空気を吹き出すものであり、したがって、内被開閉装置１４の可動被い部１０３が巻き取られて最大開放位置に巻き取り杆３８が位置するときに送風機の吹き出し空気流が可動被い部１０３により遮られない位置に設置されている。送風機の内被体内部での取り付け位置については可動被い部の最大巻き取り位置の隣接位置でなく巻き取り移動範囲の途中位置であってもよく、要は送風機の設置位置を越えて内被体の可動巻上げ開放位置が設定された構成とすればよい。さらに、実施形態において、送風機４２は、図１、図３に示すように、円筒ケース４６と円筒ケース内に回転羽根４８を設け天窓開口開閉装置６０の天窓開口６２、すなわち詳細には天窓開口に取り付けた天窓開口開閉装置６０の流路６１の開口に向けて直接に風を送風させる指向形軸流ファンから構成されている。送風機４２には図示しない正逆駆動モータが設置されて、回転羽根４８を正逆回転させる。図に示すように、送風機４２の円筒ケース４６は、その円筒軸心が内被体の円弧面への円筒ケースの投影部分の法線と略一致するように位置合わせされて送風機４２が吊支固定されている。円筒ケースは両端を開放したある程度の長さを有する中空の直円筒部材からなり、プロペラ羽根により生成した軸流空気を直線状に送風案内する機能を有している。この送風機４２により駆動されて送風される空気は直線状に流れる指向性を付与されており、したがって、該送風機４２を昼間時等に正転駆動することにより、内被体１０内の天井側の温熱空気は吸引されて断熱空間２００を通り直接に天窓開口開閉装置６０の流路開口を通流し外部へ排気される。   In the present embodiment, the first device of the direct exhaust device 8 is configured by the blower 42, and the second device is configured by the skylight opening / closing device 60. The blower 42 is an exhaust driving means for in-house air that is provided inside the inner body 10 and blows out air in the inner space 300 toward the normal direction of the arch surface or arc surface of the inner body. The air in the vicinity of the highest temperature region in the space in the house installed at or near the arch top of the inner jacket 10 is directly exhausted. In FIG. 1, the blower 42 is suspended by some of a plurality of arch members 24 by a suspension member 44 such as a wire, and the main body is installed in the inner space of the inner jacket 10. In the present embodiment, the blower 42 blows out air in the normal direction of the inner and outer cover bodies, and therefore the movable cover portion 103 of the inner cover opening / closing device 14 is wound and wound to the maximum open position. It is installed at a position where the blown air flow of the blower is not obstructed by the movable covering portion 103 when the flange 38 is located. The installation position of the blower inside the inner casing may be not the position adjacent to the maximum winding position of the movable covering portion but the middle position of the winding movement range.

As shown in the figure, the cylindrical case 46 of the blower 42 is aligned so that its cylindrical axis is substantially coincident with the normal line of the projected portion of the cylindrical case onto the arc surface of the inner casing, and the blower 42 is suspended and supported. It is fixed. The cylindrical case is formed of a hollow straight cylindrical member having a certain length with both ends open, and has a function of guiding the axial air generated by the propeller blades in a straight line. The air that is driven and blown by the blower 42 is given directivity that flows in a straight line. Therefore, by driving the blower 42 to rotate forward at daytime or the like, The hot air is sucked, passes through the heat insulating space 200, directly flows through the flow path opening of the skylight opening opening / closing device 60, and is exhausted to the outside.

直通排気装置８の第１装置としての送風機４２は、夜間時等に逆回転駆動することにより内被体１０内の天井付近の温熱空気を地面側に送風しハウス内空間３００内で上下方向に循環する対流を生じさせる。このとき、植物側に風を吹きつけることになるので、微風による送風を行なわせるのが好ましい。   The blower 42 as the first device of the direct exhaust device 8 is driven in reverse rotation at night or the like to blow hot air near the ceiling in the inner casing 10 to the ground side and vertically in the interior space 300. This causes convection to circulate. At this time, since the wind is blown to the plant side, it is preferable to blow air by a slight wind.

図１ないし図３において、直通排気装置８の第２装置としての天窓開口開閉装置６０は、内被体内側に設置された第１装置としての送風機４２と協働して内被体１０内の温熱空気を内外被体法線方向貫通状に直通排気させる直通排気手段の一構成要素であり、具体的には、外被体１２の固定被い部１２２の頂部寄り位置であって、送風機４２の円筒ケースの取り付け位置での（円筒）軸線Ｆと同軸ないしは略同軸である軸線対応位置に中心ないしは中央位置を有して形成された天窓開口６２を貫通して設置されている。詳しくは、図４に示すように、内外被体１０、１２あるいはそれらの一部範囲の法線Ｎ方向に見て送風機４２のケース円形と天窓開口６２とが少なくとも一部で重複するように送風機４２と天窓開口開閉装置６０とが位置を決められて取り付けられている。したがって、送風機４２から吹き出される空気は直接に天窓開口開閉装置６０の流路開口を通過し外部に排気される。そして、天窓開口開閉装置６０は外被体１２から一部を貫通突出する状態で複数のアーチ部材２４を介して安定的に外被体１２の頂部付近に設置固定されている。天窓開口開閉装置６０は、図３に示すように、内部に空気流路６１を有しモータ６４、ウォームギヤ機構６６、図示しない軸方向移動機構、軸方向移動機構に支持されて天窓開口６２を上下方向移動により開閉する蓋部材６８と、を含む。蓋部材６８は、傘状の外形形状をしており、上下移動開閉構造とともに全方向からの降雨の侵入防止と、天窓開口の開放による温熱空気の排気の機能を同時に行なう。天窓開口開閉装置６０は、アーチ部材２４により支持された状態で固定被い部１２２の合成樹脂フィルムの天窓開口６２に接続部分を水密施工されて貫通状に設置される。天窓開口開閉装置６０の内部の空気流路６１は、外部空間１５０にも断熱空間２００にも連通し得る。なお、図１中７０は、石油暖房機等の暖房装置、７２はハウス内空間３００の温度センサである。なお、７０は石油暖房機の代わりに冷暖房機能を有する空調装置としてもよい。   In FIG. 1 thru | or FIG. 3, the skylight opening opening / closing apparatus 60 as the 2nd apparatus of the direct exhaust apparatus 8 cooperates with the air blower 42 as a 1st apparatus installed in the inner casing inside, and the inside of the inner casing 10 It is a constituent element of the direct exhaust means for exhausting the hot air directly through the inner and outer casings in the normal direction, and more specifically, at a position near the top of the fixed covering portion 122 of the outer casing 12 and the blower 42 Is installed through a skylight opening 62 having a center or center position at a position corresponding to the axis that is coaxial or substantially coaxial with the (cylindrical) axis F at the mounting position of the cylindrical case.

Therefore, the air blown out from the blower 42 directly passes through the flow path opening of the skylight opening opening / closing device 60 and is exhausted to the outside. The skylight opening / closing device 60 is installed and fixed in the vicinity of the top of the outer casing 12 stably via the plurality of arch members 24 in a state of partially protruding from the outer casing 12. As shown in FIG. 3, the skylight opening opening / closing device 60 has an air flow path 61 therein and is supported by a motor 64, a worm gear mechanism 66, an axial movement mechanism (not shown), and an axial movement mechanism to move the skylight opening 62 up and down.

次に、本実施形態の農業用ハウスの温度調整システムの作用について図５ないし図９を参照して説明する。図５は、主に昼間における本実施形態の農業用ハウスの温度調整システムの作用を示し、図６は、主に夜間における本実施形態の農業用ハウスの温度調整システムの作用を示す。図５の昼間時において大気温度は上昇し内被体内部空間すなわちハウス内空間３００の天井付近並びに、断熱空間２００は高温域となるため内外被開閉装置１４、１６ともに全開しそれぞれの巻き取り杆３８、４０は、巻き上げ最上位置まで駆動されてそれぞれの装置の最大開口を形成した状態となっている。この状態で、直通排気装置８の天窓開口開閉装置６０の蓋部材６８を開口して内部空気流路６１を開通状態とし、さらに送風機４２を駆動させると、内被体内の天井部分の高温空気を吸引しながら円筒ケース４６の一端開口から空気を法線方向に向けて吹き出し、断熱空間２００内部で法線方向の空気流れを生成させながら天窓開口開閉装置６０の流路開口に至り、その流路６１内を一気に通過して蓋部材６８と流路の出口開口側から外部空間１５０側に排気される。この際、断熱空間２００内に滞留している温熱空気も巻き込んで排気させる。したがって、内外被体の内側天井部分やその周辺に滞留している温熱空気は一気に外部に排出されるから、夏季高温季や異常高温時等において本装置を昼間時運転で駆動させることでハウス内での異常な温度上昇を抑制できる。また、断熱層空間部分も同時に換気されハウス内全体の異常高温化を防止する。これによって、適切な植物育成環境を保持させることができる。   Next, the operation of the temperature control system for an agricultural house according to the present embodiment will be described with reference to FIGS. FIG. 5 mainly shows the operation of the temperature adjustment system of the agricultural house of the present embodiment in the daytime, and FIG. 6 mainly shows the operation of the temperature adjustment system of the agricultural house of the present embodiment in the nighttime. At daytime in FIG. 5, the atmospheric temperature rises and the inner space of the inner casing 300, that is, the vicinity of the ceiling of the house space 300, and the heat insulating space 200 are in a high temperature range, so that both the inner and outer jacket switching devices 14 and 16 are fully opened. Reference numerals 38 and 40 are driven to the uppermost winding position to form a maximum opening of each device. In this state, when the lid member 68 of the skylight opening / closing device 60 of the direct exhaust device 8 is opened to open the internal air flow path 61 and the blower 42 is driven, the high-temperature air in the ceiling portion in the inner casing is removed. While sucking, air is blown out from the one end opening of the cylindrical case 46 in the normal direction, and the air flow in the normal direction is generated inside the heat insulating space 200 to reach the flow path opening of the skylight opening opening / closing device 60. It passes through the inside of 61 at a stretch and is exhausted from the lid member 68 and the outlet opening side of the flow path to the external space 150 side. At this time, hot air staying in the heat insulating space 200 is also entrapped and exhausted. Therefore, the hot air staying in and around the inner ceiling of the inner / outer casing is exhausted to the outside at once, so the device can be driven in the house during daytime operation in the hot summer season or abnormally high temperatures. Abnormal temperature rise at the can be suppressed. In addition, the heat insulating layer space is also ventilated at the same time to prevent abnormally high temperatures in the entire house. Thereby, an appropriate plant growing environment can be maintained.

図６の夜間時において、大気温度は一般に下降し、冷気や夜露からの植物の保護を考慮する必要が生じる。夜間時は、内外被開閉装置１４、１６ともに全閉し、それぞれの巻き取り杆３８、４０は、巻き戻し最下位置まで駆動されてそれぞれ内外被体１０、１２を全閉した状態となっている。そして、直通排気装置８の天窓開口開閉装置６０の蓋部材６８を閉鎖移動して内部空気流路６１を閉鎖させる。これによって、断熱空間２００は外部空間１５０及びハウス内空間３００とも遮断された独立の断熱空間を形成し外部天候条件の影響を緩衝する。この状態で、送風機４２を逆回転でしかも低速回転駆動させると、内被体内の天井部分の温められた空気が微風で地面側に吹き付けられる。地面側に向けた空気は上下方向に還流し図６のように対流Ｆを生じさせてハウス内空間全体を均一にしかも燃料や電力コストを節約した効率のよい保温機能を行なうことができる。   At nighttime in FIG. 6, the atmospheric temperature generally falls, and it is necessary to consider the protection of plants from cold air and night dew. At night time, both the inner and outer jacket opening / closing devices 14 and 16 are fully closed, and the winding rods 38 and 40 are driven to the lowest position for rewinding, and the inner and outer jacket bodies 10 and 12 are fully closed. Yes. Then, the lid member 68 of the skylight opening / closing device 60 of the direct exhaust device 8 is closed and moved to close the internal air flow path 61. Accordingly, the heat insulation space 200 forms an independent heat insulation space that is also cut off from the external space 150 and the in-house space 300 to buffer the influence of external weather conditions. In this state, when the blower 42 is driven to rotate in the reverse direction and at a low speed, the warmed air on the ceiling portion in the inner casing is blown to the ground side with a slight wind. The air directed toward the ground side recirculates in the vertical direction and generates convection F as shown in FIG. 6 to make the entire space in the house uniform and perform an efficient heat retaining function that saves fuel and power costs.

なお、夜間においても、昼間時や夏季ハイシーズン時のように外気温が高いときには昼間と同様に内外開閉装置１４、１６と連動して天窓開口開閉装置６０ならびに送風機４２を駆動させることにより異常高温状態を回避させることができる。   Even at night, when the outside air temperature is high, such as during the daytime or high season in summer, the skylight opening / closing device 60 and the blower 42 are driven in conjunction with the inside / outside opening / closing devices 14 and 16 in the same way as in the daytime. A state can be avoided.

次に、図７、図８の動作フロー図により本実施形態のシステムの稼動の一例を説明する。図９は、その際の農業用ハウスの温度調整システムの動作の流れを表にして示す流れ表図であり、図９において、内被開閉装置１４は昼夜、降雨の有無に関わらず例えば朝７：００に開放駆動して開放維持し、夕方４：００に閉鎖駆動して閉鎖維持するタイマ制御による定時運転を行なっている。雨からの植物保護は最外部の外被体１２により行なわせるようにしている。温度センサ７２によるハウス内空間温度の温度データを受けて例えば目標温度２５℃に向けた制御指示により暖房あるいは冷房装置が駆動される。外被開閉装置１６は、降雨時は必ず全閉し、植物育成空間側への雨の影響を遮断するとともに、降雨がないときには昼間時は通常開放し夜間時は通常閉鎖する。そして、その際のハウス内温度に対応して直通排気装置８の一部又は全部を駆動させる。   Next, an example of the operation of the system of this embodiment will be described with reference to the operation flowcharts of FIGS. FIG. 9 is a flow chart showing the flow of operation of the temperature control system for an agricultural house at that time. In FIG. 9, the inner cover 14 is, for example, 7 in the morning regardless of whether it rains or not. The timer is driven to open at 0:00 to maintain the opening, and at 4:00 in the evening, the timer is driven to be closed to maintain the closing. Plant protection from the rain is performed by the outermost casing 12. Upon receiving the temperature data of the house space temperature from the temperature sensor 72, for example, the heating or cooling device is driven by a control instruction for a target temperature of 25 ° C. The jacket opening / closing device 16 is always fully closed during rain, shuts off the influence of rain on the plant growing space side, and is normally open during the day and normally closed during the night. Then, part or all of the direct exhaust device 8 is driven in accordance with the house temperature at that time.

図９の流れ表図に基づく図７の本システムの一動作例のフロー図において、昼間時の動作例が示されている。制御装置７４は、内被開閉装置１４が昼夜、降雨の有無に関わらず朝７：００開放駆動、維持、夕方４：００閉鎖駆動、維持状態を認識する（Ｓ１）。午前中でハウス内空間温度が上昇し（Ｓ２）、ハウス内温度が２５℃以下、２５℃を越えて３０℃以内、３０℃を越えて３５℃以内、３５℃を超える温度かどうかを温度センサ７２のデータから判定（Ｓ３）し、さらにその際、降雨の有無が判定される（Ｓ４）。降雨時には天窓開口６２閉鎖（Ｓ５）が確認され、さらに、外被開閉装置１６が閉鎖駆動（Ｓ６）して外被体１２を閉鎖させる。Ｓ４の段階で降雨無しの場合には、外被開閉装置１６が開放駆動（Ｓ７）し、その際にハウス内温度が２５℃以下又は２５℃を越えて３０℃以内の場合には、天窓開口開閉装置６０の蓋部材６８が閉鎖駆動し（Ｓ８）、さらに外被開閉装置１６は閉鎖駆動する（Ｓ９）。一方、ハウス内温度が３０℃を越えて３５℃以内又は３５℃を超える温度の場合には、天窓開口開閉装置６０の蓋部材６８が開放駆動し（Ｓ１０）、さらにハウス内空間温度が３５℃を超えるかどうかが判定される（Ｓ１１）。３５℃を超えない場合には、天窓開口開閉装置６０の蓋部材６８が閉鎖駆動し（Ｓ１２）、さらに外被開閉装置１６は閉鎖駆動する（Ｓ１３）。３５℃を超える場合には、内被体１０の開放状態を確認し（Ｓ１４）、送風機４２を正転駆動させる（Ｓ１５）。   In the flowchart of one operation example of the system of FIG. 7 based on the flow chart of FIG. 9, an operation example at daytime is shown. The control device 74 recognizes the inner opening / closing device 14 day and night, whether or not it is raining, in the morning at 7:00 open drive, maintenance, at 4:00 in the evening drive, and the maintenance state (S1). The temperature in the house rises in the morning (S2), and whether the temperature in the house is below 25 ° C, over 25 ° C within 30 ° C, over 30 ° C within 35 ° C, over 35 ° C. A determination is made from the data 72 (S3), and at that time, the presence or absence of rainfall is determined (S4). When it rains, the skylight opening 62 is closed (S5), and the jacket opening / closing device 16 is driven to close (S6) to close the jacket body 12. When there is no rain at the stage of S4, the jacket opening / closing device 16 is driven to open (S7), and when the house temperature is below 25 ° C or above 25 ° C and within 30 ° C, the skylight opening The lid member 68 of the opening / closing device 60 is driven to close (S8), and the jacket opening / closing device 16 is further driven to close (S9). On the other hand, when the temperature in the house exceeds 30 ° C. and is within 35 ° C. or exceeds 35 ° C., the lid member 68 of the skylight opening / closing device 60 is driven to open (S10), and the space temperature in the house is 35 ° C. It is determined whether or not (S11). When the temperature does not exceed 35 ° C., the lid member 68 of the skylight opening / closing device 60 is driven to close (S12), and the jacket opening / closing device 16 is further driven to close (S13). When the temperature exceeds 35 ° C., the open state of the inner casing 10 is confirmed (S14), and the blower 42 is driven to rotate forward (S15).

次に、図８の本システムの一動作例のフロー図において、夜間時の動作例が示されている。制御装置７４は、内被開閉装置１４の定時運転により夕方４：００閉鎖駆動、閉鎖維持状態を認識する（Ｓ２１）。夜間時は、大気温度は下降し、冷気や夜露からの植物の保護の必要から、内外被開閉装置１４、１６ともに全閉し、それぞれの巻き取り杆３８、４０は、巻き戻し最下位置まで駆動されてそれぞれ内外被体１０、１２を全閉した状態となっている（Ｓ２２），（Ｓ２３）。そして、直通排気装置８の天窓開口開閉装置６０の蓋部材６８を閉鎖移動して内部空気流路６１を閉鎖させる（Ｓ２４）。これによって、断熱空間２００は外部空間１５０及びハウス内空間３００とも遮断された独立の断熱空間を形成し外部天候条件の影響を緩衝する。この状態で、ボイラ等の暖房装置７０をオンする（Ｓ２５）と、ハウス内温度は上昇する。そして、ハウス内温度を例えば２５℃を制御目標温度とし、ハウス内センサ温度Ｔｕと２５℃を比較して（Ｓ２６）センサ温度が２５℃を越えていれば送風機４２が逆回転により地面側あるいは内側に向けて微風を送風する（Ｓ２７）（ハウス内上部の空気をした方向へ送風する）。Ｓ２６で、ハウス内温度が２５℃を超えていなければ送風機４２の動作停止を確認し（Ｓ２８）暖房装置７０を介してハウス内を暖房させる。   Next, an operation example at night is shown in the flowchart of one operation example of the system of FIG. The controller 74 recognizes the evening 4:00 closing drive and the closed maintenance state by the scheduled operation of the inner cover device 14 (S21). At night, the air temperature drops, and the inner and outer cover devices 14 and 16 are fully closed to protect the plant from cold air and night dew, and the winding rods 38 and 40 reach the lowest unwinding position. The inner and outer jackets 10 and 12 are fully closed by being driven (S22) and (S23). Then, the lid member 68 of the skylight opening / closing device 60 of the direct exhaust device 8 is closed and moved to close the internal air flow path 61 (S24). Accordingly, the heat insulation space 200 forms an independent heat insulation space that is also cut off from the external space 150 and the in-house space 300 to buffer the influence of external weather conditions. When the heating device 70 such as a boiler is turned on in this state (S25), the temperature in the house rises. Then, for example, the house temperature is set to 25 ° C., and the house sensor temperature Tu is compared with 25 ° C. (S26). If the sensor temperature exceeds 25 ° C., the blower 42 rotates reversely to the ground side or inside. A small wind is blown toward the head (S27) (the air is blown in the direction of the air in the upper part of the house). If the house temperature does not exceed 25 ° C. in S26, the operation stop of the blower 42 is confirmed (S28), and the house is heated via the heating device 70.

すなわち、夜間時には、内被開閉装置１４並びに外被開閉装置１６を閉鎖状態とし、外気の低下に対して暖房装置によりハウス内を加温しながら一方で内被体の天井側の暖かい空気を微風により地面側へと送風する。このように、送風機４２は、正逆回転式送風機から構成し、外向き法線方向に風を吹き出して外被開口開閉装置の開口から直接に内被体内側の高ハウス内温度空気を外部に排気する状態と、内向き法線方向に風を吹き出して地面側に向けて流す状態と、に選択駆動される。これによって、例えば昼間時には常時内被体内側の天井部分や断熱空間内に対流する温熱空気を短時間で排気して換気させ、育成させる植物にとって最適の温湿度環境を維持させることができる上に、夜間時において第１装置の送風機は排気とともに温熱空気の対流駆動をも兼用運転できるから、保温効率を良好にして暖房やハウス内での循環扇数の削減、循環運転の節約等の効果を奏し得る。なお、上記したフローチャート図に示した温度調整システムの昼間、夜間時の動作例は一つの例にすぎず、本発明の農業用ハウスの温度調整システムは、上記の実施形態の動作例に限定されるものではない。例えば、夜間時においても異常高温が想定される現場での使用時には昼間時と同様に、高温時での内外被開閉装置１４、１６、天窓開口開閉装置６０、送風機４２の駆動を併せて、直通排気装置８を適宜駆動させるようにするとよい。   That is, at night, the inner cover device 14 and the outer cover device 16 are closed, and the warm air on the ceiling side of the inner cover is slightly blown while the inside of the house is heated by the heating device against a decrease in the outside air. To blow to the ground side. In this way, the blower 42 is constituted by a forward / reverse rotating blower, blows wind in the outward normal direction, and directs the high-house temperature air inside the inner casing directly from the opening of the outer jacket opening / closing device to the outside. It is selectively driven into a state of exhausting and a state of blowing out wind in the inward normal direction and flowing it toward the ground side. This makes it possible to maintain the optimum temperature and humidity environment for the plant to be cultivated by exhausting and ventilating the hot air convectively in the ceiling part and the heat insulation space inside the inner body at all times during the daytime, for example. The night blower of the first device can also be used for both hot air and convection drive at night, improving heat insulation efficiency, reducing the number of fans in the heating and circulation, and saving circulation operation. Can play. The operation example of the temperature adjustment system shown in the flowchart in the daytime and nighttime is only one example, and the temperature adjustment system of the agricultural house of the present invention is limited to the operation example of the above embodiment. It is not something. For example, at the time of use at a site where an abnormally high temperature is assumed even at night, as in the daytime, the inner and outer jacket opening and closing devices 14 and 16, the skylight opening and closing device 60, and the blower 42 are driven directly. The exhaust device 8 may be driven appropriately.
