【発明の属する技術分野】
この発明は、ビニールハウス内冷暖房及び消毒用土壌ベッドに関する。
【0002】
【従来の技術】
従来、ビニールハウス内の冷暖房設備は、例えば暖房設備としてボイラーを用い、ボイラーからの熱を、ビニールハウス内に敷設した熱風ホースから送風してビニールハウス内を加温する方法がとられていたり、冷房設備としては、クーラーからの冷風を冷風ホースを介してビニールハウス内に送風する方法等が採られていた。更には、ビニールハウス内の消毒は、消毒薬品を使用し、例えば、臭化メチルやクロロピリン等の猛毒薬品を使用していた。
【0003】
【発明が解決しようとする課題】
ところが、これらの方法は、ハウス内の空間のみを冷暖房する方法であり、土壌そのものの冷暖房化は、更に土壌中に冷暖房用のパイプを埋設したり敷設したりする必要が生起する。従って、ビニールハウス内の空間は勿論、土壌も同時に加温或は冷却する設備が求められていた。更には、猛毒薬品による消毒はハウス内の生態系に支障をきたすおそれがあった。
【0004】
【課題を解決するための手段】
この発明は、ビニールハウス内に土壌ケースを設置し、土壌ケースは熱伝導の良好な材質を用いており、土壌ケースの内底面には溝を形成し、溝中には伝熱粒子を充填し、伝熱粒子中にヒートパイプを埋設すると共に、ビニールハウスの天井部近傍に冷暖房用の伝熱パイプを配設してなる、ビニールハウス内冷暖房及び消毒用土壌ベッドを提供せんとするものである。
また、ビニールハウス内に設置される土壌ケースを有し、土壌ケースは熱伝導の良好な材質を用いており、土壌ケースの内底面には溝を形成し、溝中には伝熱粒子を充填し、伝熱粒子中にヒートパイプを埋設すると共に土壌ケースの内底面には放熱板を張設し、さらにビニールハウスの天井部近傍に冷暖房用の伝熱パイプを配設してなる、ビニールハウス内冷暖房及び消毒用土壌ベッドを提供せんとするものである。
【0005】
また、本発明は、伝熱パイプ中に、太陽熱利用による温水を通水すること、及び、伝熱パイプにヒートパイプ機能を保持させたことにも特徴を有する。
【0006】
【発明の実施の形態】
この発明では、ヒートパイプの真空パイプ中に挿貫した熱源パイプ中に冷却水或は温水を流入することにより、真空パイプ中の熱媒用流体を介して真空パイプを冷却或は加温し、土壌ケースを介して同ケース中の土壌を冷却・加温する。
【0007】
土壌中を冷却・加温すると同時に土壌ケースそのものが熱伝導率が良好なために、ヒートパイプからの熱は土壌ケースを伝導し、ビニールハウス内の空気そのものも冷却・加温することになり、ビニールハウス内の冷暖房機能も果すことができる。
【0008】
また、ヒートパイプにより土壌ケース内の土壌も加熱されることにより土壌消毒も可能となるものである。
【0009】
なお、ビニールハウスの天井にスプリンクラーを設置すれば、土壌や植栽植物への散水も可能となる。
【0010】
更には、ビニールハウスの天井部近傍に配設した冷暖房用の伝熱パイプには太陽熱利用による温水を通水し、或はヒートパイプ機能を保持させているので、省エネルギーでハウス内の加温、冷却が行える。
【0011】
【実施例】
この発明の実施例を図面にもとづき詳説すれば、図1はビニールハウス内冷暖房設備を示すものであり、Aはビニールハウスであり、ビニールハウスA内には、基台1を敷設しており、該基台1は発泡スチロール等を素材としている。
【0012】
基台1上には上方開口の熱伝導率の良好な土壌ケース2を載置している。
【0013】
土壌ケース2は、断面略凹状の形状に構成されており、コンクリート等の熱伝導の良好な材質を用いており、土壌ケース2の内底面には溝3を形成し、溝3中には砂やセラミックス粒子等の伝熱粒子4或は断熱素材を充填し、伝熱粒子4中にヒートパイプMを埋設している。
【0014】
ヒートパイプMは、図2に示すように、熱伝導率のよい銅製の真空パイプM-1中にアルコール系のエタノール、メタノール等、或はこれにシリカゲルを混入した熱媒用流体M-2 を封止しており、しかも真空パイプM-1 中には、熱源パイプM-3 を挿貫しており、熱源パイプM-3 の端部からは湯、油等を流入させてヒートパイプ中の熱媒用流体M-2 で熱交換するように構成されている。
【0015】
土壌ケース2の内底面には、銅板、アルミ板等の金属板よりなる放熱板5を張設し、その上面には耐酸性、耐久性のゴム板6を張設している。
【0016】
このように、内底面に放熱板5、ゴム板6を張設した土壌ケース2中には、植物栽培用の土壌aを充填し、植物bを栽培している。
【0017】
ビニールハウスAの天井近傍には冷暖房用の伝熱パイプNが配設されており、該伝熱パイプNは、ビニールハウスAの外部に設置した太陽熱利用による温水を通水可能に構成されている。
【0018】
すなわち、伝熱パイプNをソーラーシステムnと連通して、太陽熱により加温された温水を通水することにより暖房エネルギーを省力化するものである。
【0019】
かかるソーラーシステムnからの温水は、伝熱パイプN以外にも前述したヒートパイプM中に通水することもでき、更に省エネルギーを促進することができる。
【0020】
また、他の実施例は伝熱パイプNをヒートパイプにて構成してヒートパイプ機能をもたせるものである。
【0021】
ヒートパイプは、すでに前述した通りの構成と機能を有するものを使用する。
【0022】
ヒートパイプや太陽熱利用の温水による加温は、上記の実施例に記載した通りであるが、ヒートパイプMや伝熱パイプN中に冷却水を通水すれば、ビニールハウスの冷却も行えるものである。
【0023】
この発明の実施例は、上記のように構成されており、熱源パイプM-3 にソーラーシステムnからの熱湯を送管M-4 を介して流入させると、ヒートパイプMを介してその周辺の伝熱粒子4に伝熱し、放熱板5を介して土壌ケース2を全体的に加熱し、土壌aを加熱する。土壌aに吸湿された水分はゴム板6により遮断される。
【0024】
加熱された土壌aは熱消毒されており、しかも加温された土壌は、密封されたビニールハウスA内の空気も加熱することになり、効率的なビニールハウス温暖作用を果すことができる。同時に、天井部近傍の伝熱パイプNも空気を加熱することになり、更にビニールハウス中の暖房効率を向上する。
【0025】
特に、ヒートパイプから放熱板を介して土壌中に直接に伝熱するため、効率のよい加熱作用と消毒作用が果しうると共に、土壌ケースの伝熱性と土壌からの加温蒸気とによりビニールハウス内を効果的に加温、消毒し、従来のビニールハウスの加温技術にもとづく栽培とは全く異なる効率的なビニールハウス栽培が行える。更には必要に応じて冷却作用を果しうるため、植物の品質の向上も果しうる。
【0026】
【効果】
この発明によれば、ビニールハウス内の土壌ケースの内底面にヒートパイプを敷設し天井部近傍に伝熱パイプを配設しているので、土壌の加温による消毒効果を得ることができると共に、熱伝導率の良好な土壌ケースを介してビニールハウス内の冷暖房も行うことができる。特にヒートパイプの簡単な伝熱効率のよい構造によりビニールハウス内の冷暖房設備も簡単に設置することができる効果がある。更には、太陽熱利用による温水を使用することにより暖房コストも大幅に低減することができる効果がある。

However, these methods are methods for cooling and heating only the space in the house. In order to cool and heat the soil itself, it is necessary to embed or lay pipes for cooling and heating in the soil. Accordingly, there has been a demand for a facility for heating or cooling the soil as well as the space in the greenhouse. In addition, disinfection with highly toxic chemicals could interfere with the ecosystem in the house.
[0004]
[Means for Solving the Problems]
In this invention, a soil case is installed in a greenhouse, and the soil case is made of a material having good heat conductivity. A groove is formed on the inner bottom surface of the soil case, and the groove is filled with heat transfer particles. In addition, a heat pipe is embedded in the heat transfer particles, and a heat transfer pipe for cooling and heating is arranged near the ceiling of the greenhouse, and a soil bed for cooling and heating and disinfecting the greenhouse is provided. .
In addition, it has a soil case installed in the greenhouse, and the soil case is made of a material with good heat conduction. A groove is formed on the inner bottom surface of the soil case, and the groove is filled with heat transfer particles. A plastic greenhouse, in which heat pipes are embedded in the heat transfer particles, a heat sink is stretched on the inner bottom surface of the soil case, and a heat transfer pipe for cooling and heating is disposed near the ceiling of the plastic house. It is intended to provide soil cooling and heating and disinfecting soil beds.
[0005]
The present invention is also characterized in that hot water is passed through the heat transfer pipe by utilizing solar heat, and that the heat pipe function is maintained in the heat transfer pipe.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
In this invention, by flowing cooling water or hot water into the heat source pipe inserted into the vacuum pipe of the heat pipe, the vacuum pipe is cooled or heated via the heat medium fluid in the vacuum pipe, The soil in the case is cooled and warmed through the soil case.
