Description
本発明は食品室の結露防止構造に関する。 The present invention relates to a dew condensation prevention structure of a food room.
結露は室内外の寒暖の差により発生する事は公知の事実であることから、従来の技術は外気温度を食品部屋に侵入させないために発泡系断熱材や繊維系断熱材を屋根又は壁面内に取り入れてきた。 Since it is a known fact that dew condensation occurs due to the difference in temperature between indoors and outdoors, the conventional technology puts a foam-based heat insulating material or a fiber-based heat insulating material inside the roof or the wall surface in order to prevent the outside air temperature from entering the food room. I have taken it in.
また、前記断熱材は、強度が弱く又は水分が吸い込みやすいと云う問題点から剥き出し状態には出来ないため石膏ボードや塩化ビニルクロス等の表面材が必要であった。 Further, since the heat insulating material cannot be exposed due to the problem of weak strength or easy absorption of moisture, a surface material such as gypsum board or vinyl chloride cloth is required.
更に、食品部屋は在庫している食品の鮮度保持のためにエアコン等で冷やすことが通例である。 Furthermore, it is customary to cool the food room with an air conditioner or the like in order to maintain the freshness of the food in stock.
以上に述べた従来の構造体では、断熱材も表面材も分厚い物質（以下「蓄冷物質」という）であることから、入出庫口のシャッターを開放し食品部屋に暖気が入った場合でも一度冷え切った蓄冷物質は中々温度が上がらず外気温と一体化するまでは時間を要し高い温度の外気温と中々冷えない蓄冷物質が衝突するために結露が発生する。 In the conventional structure described above, both the heat insulating material and the surface material are thick substances (hereinafter referred to as "cold storage substances"), so even if the shutter of the entrance / exit is opened and warm air enters the food room, it cools once. Condensation occurs because the temperature of the cut cold storage material does not rise and it takes time to integrate with the outside air temperature, and the high temperature outside air temperature collides with the cold storage material that does not cool down.
本発明は、従来の構造体が有していた問題を解決しようとするものであり食品部屋に生ずる結露を発生させる事がない構造体を提供することを目的とするものである。 An object of the present invention is to solve a problem that a conventional structure has, and to provide a structure that does not cause dew condensation to occur in a food room.
そして、本発明は上記目的を達成するために、食品部屋の構造体表面に対流熱に極めて弱く熱伝導しやすいアルミ箔を表面材とした。 In order to achieve the above object, the present invention uses an aluminum foil as a surface material on the surface of the structure of the food room, which is extremely weak against convection heat and easily conducts heat.
また、表面材のアルミ箔は、表裏２枚のアルミ箔７．２ミクロン極薄タイプと３層のポリエチレンシートと２層のバブル型ポリエチレンシートの７層構造体シート（以下「遮熱シート」という）を使用した。 The aluminum foil as the surface material is a 7-layer structure sheet consisting of two aluminum foils on the front and back, an ultra-thin 7.2 micron type, a three-layer polyethylene sheet, and a two-layer bubble type polyethylene sheet (hereinafter referred to as "heat shield sheet"). )It was used.
更に、衝撃を受けやすい床から上方向に１ｍ前後には、表のアルミ箔７６ミクロンの厚
手タイプと裏面のアルミ箔は７．２ミクロン厚であり、内部には３層のポリエチレンシートと２層のバブル型ポリエチレンシートの７層構造体シート（以下「片厚遮熱シート」という）を使用する。
Furthermore, about 1 m upward from the floor, which is susceptible to impact, the aluminum foil on the front side is 76 microns thick and the aluminum foil on the back side is 7.2 microns thick. Inside, there are three layers of polyethylene sheets and two layers. 7-layer structure sheet of bubble type polyethylene sheet (hereinafter referred to as "single-thickness heat shield sheet") is used.
本発明の構造体には前記遮熱シート又は片厚遮熱シートを使用するが、それ以外の金属等の物質であっても対流熱に素早く影響される素材なら使用しても良い結果が生ずる。 The above-mentioned heat shield sheet or single-thickness heat shield sheet is used for the structure of the present invention, but other substances such as metals may be used as long as they are materials that are quickly affected by convection heat. ..
構造体表面に使用する遮熱シートと片厚遮熱シートは出荷時入出庫口が開放されたとき熱力学記載通り暖かい外気の熱は暖かい方から低い方へ移動し食品部屋に侵入するが侵入と同時に対流熱に極度に弱いアルミ箔にぶつかり、外気温とアルミ箔温度が素早く一体化してしまう。 The heat shield sheet and single-thickness heat shield sheet used for the surface of the structure are shipped. When the entrance / exit port is opened, the heat of the warm outside air moves from the warm side to the lower side and invades the food room as described in thermodynamics. At the same time, it hits the aluminum foil, which is extremely sensitive to convection heat, and the outside air temperature and the aluminum foil temperature are quickly integrated.
以上の通り、外気温と食品部屋の壁天井に貼られた遮熱シート又は片厚遮熱シートは、ほぼ同温度に成る事から結露の発生を防ぐ事が可能である。 As described above, the heat shield sheet or the single-thickness heat shield sheet attached to the wall ceiling of the food room has almost the same temperature as the outside air temperature, so that it is possible to prevent the occurrence of dew condensation .
つまり、本特許は、本来なら対流熱に極めて弱いと云う問題物質を逆手に取り、この弱点を有効利用して結露防止対策とした独自の発想構造である。 In other words, this patent is a unique idea structure that takes advantage of the problematic substance, which is originally extremely weak against convection heat, and effectively utilizes this weakness to prevent dew condensation .
上述したように本発明の工法は、食品部屋から商品の搬出時、結露が発生させる事の無い構造を提供できる。 As described above, the construction method of the present invention can provide a structure in which dew condensation does not occur when the product is carried out from the food room.
更に結露が発生すれば必ずカビが発生する。カビはトリコスポロン種であり目に見えない胞子が乱舞し食品に付着してしまう。近年この胞子を吸引するとトリコスポロン病と云う急性肺炎を誘発することが分かった。従って本発明によりカビによる健康障害を防ぐ事ができる。 Furthermore, if dew condensation occurs, mold will always occur. Mold is a trichosporon species, and invisible spores dance and attach to food. In recent years, it has been found that inhalation of these spores induces acute pneumonia called trichosporon disease. Therefore, according to the present invention, it is possible to prevent health problems caused by mold.
以下、本発明の実施の形態を図１〜図３に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.
食品部屋図２の６は図１で示す遮熱シートを下地材４にスペーサー５を設けその上に施工した食品部屋の本考案施工後の壁面と天井の断面図である。
6 of FIG. 2 is a cross-sectional view of the wall surface and ceiling of the food room after the present invention is constructed, in which the heat shield sheet shown in FIG. 1 is provided with a
下地材４と図１の遮熱シート間にはスペーサー５を設けた事で静止空気層７を得た。静止空気層が有る事で表面のアルミ箔１の暖冷変化を裏面の下地材に伝導型熱移動を伝えることが緩和される。
A
図１の遮熱材は、表裏表面ともアルミ箔厚が７．２ミクロン付近であるが、衝撃の可能性を考慮し表面だけ７６ミクロン付近にしてそれに耐えうる遮熱シートを用意した。床から１ｍ前後はこの片厚遮熱シートが
好適に用いられる。
The heat shield material in FIG. 1 has an aluminum foil thickness of about 7.2 microns on both the front and back surfaces, but in consideration of the possibility of impact, a heat shield sheet capable of withstanding it was prepared by setting only the surface to about 76 microns. This single-thickness heat shield sheet is preferably used for about 1 m from the floor.
本来、建物の表面には合板や石膏ボードやビニルクロス等の内装材と称する材料を施工するが、その物体はホリュームが有るため、暑いときは蓄熱体、寒いときには蓄冷体と化
すことで問題を多発してきた。
従って本発明はそれらの部材を排除したのも特徴である。
Originally, materials called interior materials such as plywood, gypsum board, and vinyl cloth are applied to the surface of the building, but since the object has a volume, it becomes a heat storage body when it is hot and a cold storage body when it is cold. It has occurred frequently.
Therefore, the present invention is also characterized by eliminating those members.
以上に説明の通り食品部屋の壁天井を構成すれば、結露とその後のカビ発生の心配の無い空間が得られるものである。
本明細書は下記の構成を開示する。
（１） 対流型熱移動に弱い７．２ミクロンの極薄なアルミ箔シートを出荷用食品室又は出入り口付近の壁天井の表面材に用いる事で結露を防ごうとした施工方法。
（２） 衝撃を受けやすい床から１ｍ前後の壁面には片面のみ７６ミクロン付近厚の遮熱シートを使った出荷用食品室又は出入り口付近の施工方法。
（３） 遮熱シートと下地材の空間にはスペーサーを設けた事で得られる静止空気層を持つ出荷用食品室又は出入り口付近の壁天井の施工方法。
As described above, if the wall ceiling of the food room is constructed, a space without worrying about dew condensation and subsequent mold formation can be obtained.
The present specification discloses the following configurations.
(1) A construction method in which dew condensation is prevented by using a 7.2 micron ultra-thin aluminum foil sheet, which is vulnerable to convection heat transfer, as a surface material for a wall ceiling near a food room for shipping or a doorway.
(2) A construction method near the food room for shipping or the doorway using a heat shield sheet with a thickness of about 76 microns on only one side of the wall surface about 1 m from the floor that is susceptible to impact.
(3) A method of constructing a wall ceiling near a shipping food room or an entrance / exit having a static air layer obtained by providing a spacer in the space between the heat shield sheet and the base material.
