Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、プラスチックフィルム等よりなる簡易ダク
ト式熱交換装置に関するものである。TECHNICAL FIELD The present invention relates to a simple duct heat exchange device made of a plastic film or the like.
（従来の技術及び解決すべき課題） 従来、熱交換装置はその熱効率の点から熱伝導率の良
い金属で作られている。しかして、金属製のものは装置
自体が重く、また変形しにくいことから、取付け、取外
しが困難で、半永久的な装置となっている。(Prior Art and Problems to be Solved) Conventionally, a heat exchange device is made of a metal having a high thermal conductivity in view of its thermal efficiency. However, since the device made of metal is heavy and is not easily deformed, it is difficult to mount and remove, and it is a semi-permanent device.
使用目的によっては取付け、取外しが容易であればよ
く、熱効率もそれほど重視しなくてもよい場合もある
が、従来は殆どが従来からの考えにとらわれ金属で作ら
れていた。Depending on the purpose of use, it may be easy to attach and detach, and in some cases it is not necessary to give much importance to thermal efficiency, but in the past, most of them have been made of metal by the conventional idea.
例えば、温室やビニールハウスなどのように栽培室内
の温度を冷暖房によって温度調節して野菜を生産する場
合には、空調システムに要するイニシャルコスト、ラン
ニングコストがそれぞれ大きなコストを占めている。特
に、ビニールハウスなどの場合、高価な空調装置を設備
しても建物自体が安価で、永久的のものでないため全く
不経済である。そのため、現在ではプロパンガス等を直
接焚いて暖をとっているが、この方法では室内の空気の
質を調節できない。また、冷房には適切な方法がないの
が現状である。For example, in the case where vegetables are produced by adjusting the temperature in the cultivation room by heating and cooling, such as in greenhouses and greenhouses, the initial cost and running cost required for the air conditioning system occupy large costs. In particular, in the case of a vinyl house or the like, even if an expensive air conditioner is installed, the building itself is inexpensive and not permanent, which is completely uneconomical. Therefore, at present, propane gas or the like is directly heated for warming, but this method cannot control the quality of indoor air. In addition, there is currently no suitable method for cooling.
本発明は、これらの要望に応えるためのものである。 The present invention addresses these needs.
（課題を解決するための手段） 本発明のダクト式熱交換装置は、 プラスチックフィルム等のフィルムからなる外筒と内筒
とで構成される二重ダクトと、 該ダクトの外筒と内筒の間に挿通される適当な間隔で給
水孔を設けた給水パイプと、 該ダクトの内筒内に送風するための送風機 とからなることを特徴とする。(Means for Solving the Problems) A duct heat exchange device of the present invention is a dual duct composed of an outer cylinder and an inner cylinder made of a film such as a plastic film, and an outer cylinder and an inner cylinder of the duct. It is characterized by comprising a water supply pipe having water supply holes provided at appropriate intervals, and a blower for blowing air into the inner cylinder of the duct.
本発明において、二重ダクトは、その長さ方向に送風
機からの風が吹き抜ける構造でもよいし、またその長さ
方向に適当な間隔で内筒と外筒を貫通する複数個の通気
孔を設け、該通気孔の周縁は内筒と外筒との間を流れる
冷暖房水がこの通気孔から流出しないように、接合シー
ルされた構造としてもよい。このように、ダクトに通気
孔を設けた場合には、ダクトの一端を閉止して送風機か
らの風が全て通気孔から出るようにしてもよい。通気孔
の大きさ、設ける間隔は任意に設定できる。In the present invention, the double duct may have a structure in which the wind from the blower blows through in the lengthwise direction, or a plurality of ventilation holes penetrating the inner cylinder and the outer cylinder at appropriate intervals in the lengthwise direction are provided. The periphery of the ventilation hole may have a joint-sealed structure so that the cooling / heating water flowing between the inner cylinder and the outer cylinder does not flow out from the ventilation hole. As described above, when the duct is provided with the ventilation hole, one end of the duct may be closed so that all the air from the blower exits from the ventilation hole. The size of the vent holes and the intervals at which they are provided can be set arbitrarily.
ダクトは、単に内筒と外筒とで形成してもよい。ダク
トは通常、ポリエチレン、ポリプロピレン等の安価なプ
ラスチックフィルムで作るが、これらは撥水性であるた
め、内・外筒の間を水が均一に流れダクトを一様に濡ら
すように、織布、不織布等の親水性シートを介在させる
とよい。親水性シートは内筒または外筒の何れかに貼り
合わせてもよい。なお、フィルム自体を親水性処理して
もよく、またダクト材として親水性フィルムを使用して
もよい。The duct may be formed simply by the inner cylinder and the outer cylinder. Ducts are usually made of inexpensive plastic films such as polyethylene and polypropylene, but since they are water repellent, woven or non-woven fabric is used so that water flows evenly between the inner and outer cylinders to evenly wet the ducts. It is advisable to interpose a hydrophilic sheet such as. The hydrophilic sheet may be attached to either the inner cylinder or the outer cylinder. The film itself may be subjected to a hydrophilic treatment, or a hydrophilic film may be used as the duct material.
ダクトの構成材料としては上記フィルムのほか、目的
に応じてポリエステル、ナイロン等の強度のある高価な
フィルムを使用してもよい。また、必要に応じてアルミ
箔、発泡シート等を貼り合わせて熱伝導性を改良したラ
ミネートフィルムを使用してもよい。As the constituent material of the duct, besides the above-mentioned film, a strong and expensive film such as polyester or nylon may be used depending on the purpose. If necessary, a laminate film having improved thermal conductivity by bonding aluminum foil, a foamed sheet or the like may be used.
ダクトの構成材料としてのフィルムの厚さは特に限定
されないが、通常0.1〜0.2mm程度のものを用いるとよ
い。The thickness of the film as a constituent material of the duct is not particularly limited, but it is usually preferable to use a film having a thickness of about 0.1 to 0.2 mm.
ダクトは、通常軟質プラスチックフィルムで作成する
が、場合によってはポリカーボネート、硬質ポリ塩化ビ
ニル等の硬質プラスチックで作成してもよい。軟質フィ
ルムの場合には、不使用時にはフィルムが板状に垂れ下
がり場所を取らないため有利である。The duct is usually made of a soft plastic film, but in some cases, it may be made of a hard plastic such as polycarbonate or hard polyvinyl chloride. In the case of a soft film, it is advantageous because the film does not hang down like a plate and occupies no space when not in use.
給水パイプは、金属製でもプラスチック製でも使用で
きる。The water supply pipe can be made of metal or plastic.
また、送風機は通常のものを使用してよい。 Further, a normal blower may be used.

内を空調できる。(Operation) Since the device of the present invention is made of a plastic film which is inexpensive and easy to carry, it can be easily attached and detached and installed in any place. Since air conditioning can be performed with cold water and hot water, the room can be air-conditioned without polluting the air in the room.
