Description
本考案は蓄熱保温構造に係り、特にパテ材を使用した高機能で低コストな蓄熱保温構造に関するものである。 The present invention relates to a heat storage and heat retention structure, and in particular to a highly functional and low cost heat storage and heat retention structure using putty material.
電気温水器などの大型機器は屋外に設置されることが多いが、屋外では電気温水器が外気に晒されて温水の熱が奪われやすい。このため、電気温水器の周囲に発泡スチロール製の断熱カバーを接着剤で固定することが通常行われている。 Large appliances such as electric water heaters are often installed outdoors, but when outdoors, electric water heaters are exposed to the outside air and the heat from the hot water is easily lost. For this reason, it is common practice to fix a heat insulating cover made of Styrofoam around the electric water heater with an adhesive.
しかし、発泡スチロール製の断熱カバーを製造するには発泡樹脂を射出成形する金型が必要であり、この金型は電気温水器の個々の複雑形状に対応した専用品になるため断熱カバーが高コスト化するという課題があった。また、断熱カバーの取り付けには接着剤の塗布など手間がかかるうえ、電気温水器と断熱カバーとの間には必然的に隙間ができてしまうので、この隙間に結露水が溜まって電気温水器が経時で腐食したり、カビが発生したりするといった課題もあった。 However, manufacturing a Styrofoam insulation cover requires a mold for injection molding the foamed resin, and this mold is a specialized product that corresponds to the complex shape of each electric water heater, making the insulation cover expensive. There was the issue of becoming a In addition, installing the insulation cover takes time and effort, such as applying adhesive, and there is inevitably a gap between the electric water heater and the insulation cover, so condensation water accumulates in this gap and the electric water heater There were also problems such as corrosion and mold growth over time.
一方、断熱カバーは熱の出入りを遮断する断熱性には優れているが、外部の熱を積極的に内側に取り込む作用はない。このため屋外において断熱カバーの外側に太陽熱が作用しても、この太陽熱は断熱カバーで遮断されるため電気温水器の保温にはまったく役に立っていない。 On the other hand, a heat insulating cover has excellent insulation properties that block heat from entering and exiting, but it does not have the effect of actively drawing outside heat into the inside. Therefore, even if solar heat acts on the outside of the insulating cover outdoors, this solar heat is blocked by the insulating cover and is of no use in keeping the electric water heater warm.
そこで本考案の目的は、発泡スチロール製の断熱カバーに代えて低コストなパテ材を電気温水器などの被保温体の周囲に塗布することで、太陽熱などの外部の熱を被保温体の保温に積極的に役立てることにある。 Therefore, the purpose of this invention is to apply a low-cost putty material around the object to be kept warm, such as an electric water heater, instead of using a heat-insulating cover made of polystyrene foam, so that external heat such as solar heat can be used to keep the object warm. The goal is to actively help.
前記課題を解決するため、本考案の蓄熱保温構造は、被保温体の外側に塗布される白色パテ材による内層と、当該内層の外側に塗布される黒色パテ材による外層とを有することを特徴とする。 In order to solve the above problems, the heat storage and heat retention structure of the present invention is characterized by having an inner layer made of a white putty material applied to the outside of the object to be kept warm, and an outer layer made of a black putty material applied to the outside of the inner layer. shall be.
本考案の蓄熱保温構造は、黒色パテ材による外層で太陽熱などの外部の熱を取り込んで蓄熱し、当該蓄熱を外層に保持して内側の被保温体からの放熱を抑制すると共に、白色パテ材による内層で被保温体からの放熱を反射・抑制することで、被保温体を効果的に保温することができる。 The heat storage and heat retention structure of the present invention captures and stores external heat such as solar heat in the outer layer made of black putty material, retains the heat storage in the outer layer, suppresses heat radiation from the inner heat insulation object, and uses white putty material to absorb and store heat. By reflecting and suppressing heat radiation from the object to be kept warm with the inner layer, the object to be kept warm can be effectively kept warm.
以下、本考案の実施形態を図面を参照して説明する。図１Ａは本考案の実施形態に係る蓄熱保温構造の断面図を示し、電気温水器などの被保温体Ａの表面に白色パテ材層Ｂによる内層が形成され、この内層の外側に黒色パテ材層Ｃによる外層が形成されている。内層と外層は吹付けにより塗布形成するのが最も簡単であるが、ヘラやスポンジローラなどを使用して塗布形成してもよいことは勿論である。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A shows a cross-sectional view of a heat storage and insulation structure according to an embodiment of the present invention, in which an inner layer made of a white putty material layer B is formed on the surface of an object A to be kept warm, such as an electric water heater, and a black putty material layer B is formed on the outside of this inner layer. An outer layer is formed by layer C. It is easiest to form the inner layer and the outer layer by spraying, but it goes without saying that they may also be formed by using a spatula, sponge roller, or the like.
白色パテ材層Ｂと黒色パテ材層Ｃに使用するパテ材は次のようにして作る。まず粉末状の白色パテ材と黒色パテ材を規定量の水を入れた別々の容器に少しずつ散布・追加し、ハンドミキサー等で撹拌・混練しながら適度な粘度になるように水または粉末パテを加えて混練・調整する。白色パテ材には白色顔料、黒色パテ材には黒色顔料をそれぞれ適量混入する。 The putty materials used for the white putty material layer B and the black putty material layer C are made as follows. First, sprinkle and add powdered white putty material and black putty material little by little into separate containers containing the specified amount of water, and mix and knead with a hand mixer etc. until the water or powdered putty material reaches the appropriate viscosity. Add and knead and adjust. Appropriate amounts of white pigment and black pigment are mixed into the white putty material and the black putty material, respectively.
白色パテ材と黒色パテ材には、ウレタン系マトリックス樹脂、アクリル系マトリックス樹脂又はエポキシ系マトリックス樹脂などを使用することができる。また白色顔料には酸化チタン等、黒色顔料にはカーボンブラック等を使用することができる。 For the white putty material and the black putty material, urethane matrix resin, acrylic matrix resin, epoxy matrix resin, or the like can be used. Furthermore, titanium oxide or the like can be used as a white pigment, and carbon black or the like can be used as a black pigment.
白色顔料の混入量は、白色パテ材層Ｂの反射率が波長範囲７８０ｎｍ～２５００ｎｍの太陽光近赤外領域で５０％以上、好ましくは６５％以上、より好ましくは８５％以上の高反射率が得られるように調整する。また黒色顔料の混入量は、黒色パテ材層Ｃの反射率が波長範囲７８０ｎｍ～２５００ｎｍの太陽光近赤外領域で３０％以下、好ましくは２０％以下、より好ましくは１０％以下の低反射率が得られるように調整する。 The amount of white pigment mixed is such that the white putty material layer B has a high reflectance of 50% or more, preferably 65% or more, more preferably 85% or more in the sunlight near-infrared wavelength range of 780 nm to 2500 nm. Adjust as desired. The amount of black pigment mixed is such that the black putty material layer C has a low reflectance of 30% or less, preferably 20% or less, more preferably 10% or less in the sunlight near-infrared wavelength range of 780 nm to 2500 nm. Adjust so that it is obtained.
白色と黒色のパテ材を用意できたら、最初に白色パテ材をスプレーガンで被保温体Ａの表面に吹き付けて内層を形成する。内層がある程度乾いたら、今度は黒色パテ材を同じようにして内層の表面に吹き付けて外層を形成する。被保温体Ａと内層Ｂは密着し、また内層Ｂと外層Ｃも密着するのでこれらの間に隙間が発生しない。したがって、被保温体Ａを屋外に配置しても、被保温体Ａの周囲に結露やカビが発生したりすることがない。 Once the white and black putty materials are prepared, first spray the white putty material onto the surface of the object A to be kept warm using a spray gun to form an inner layer. Once the inner layer has dried to some extent, spray black putty on the surface of the inner layer in the same way to form the outer layer. Since the body to be kept warm A and the inner layer B are in close contact with each other, and the inner layer B and the outer layer C are also in close contact with each other, there is no gap between them. Therefore, even if the heat-retaining object A is placed outdoors, dew condensation and mold will not form around the heat-retaining object A.
図１Ｂは、図１Ａの内層Ｂと外層Ｃを入れ替えて、黒色パテ材層Ｃで内層を形成し、白色パテ材層Ｂで外層を形成した比較例１である。また図１Ｃは、被保温体Ａの外側に発泡スチロール層Ｄ（ＦＶ５０）による断熱カバーを装着した比較例２である。また図１Ｄは、被保温体Ａの外側に黒色パテ材層Ｅだけを形成した参考例である。黒色パテ材層Ｅの厚みは図１Ａの白色パテ材層Ｂと黒色パテ材層Ｃの合計厚みにしてある。 FIG. 1B shows Comparative Example 1 in which the inner layer B and the outer layer C in FIG. 1A were exchanged, and the inner layer was formed with the black putty material layer C, and the outer layer was formed with the white putty material layer B. Further, FIG. 1C shows Comparative Example 2 in which a heat insulating cover made of a foamed polystyrene layer D (FV50) was attached to the outside of the heat insulated body A. Further, FIG. 1D is a reference example in which only a black putty material layer E is formed on the outside of the heat-retaining body A. The thickness of the black putty material layer E is the total thickness of the white putty material layer B and the black putty material layer C in FIG. 1A.
図２は蓄熱保温効果を調べる実験装置の概略図である。図１Ａの蓄熱保温構造を形成した矩形板状の被保温体Ａを基台Ｆの上に水平に配置し、黒色パテ材層Ｃの表面と白色パテ材層Ｂの裏面の温度を測定するためにサーモメータＴ１、Ｔ２（アンリツ製COMPACT THERMO
ROGGER AM-8000K）を配置する。被保温体Ａの真上の高さＨ（５５ｃｍ）の位置に配置した赤外線ランプヒータＬ（東芝製ビームランプＭＸ，１１０ｖ，１５０Ｗ）で黒色パテ材層Ｃを１２０分間照射した。
FIG. 2 is a schematic diagram of an experimental apparatus for examining the heat storage and heat retention effect. To measure the temperature of the surface of the black putty material layer C and the back surface of the white putty material layer B by placing the rectangular plate-shaped heat insulation object A formed with the heat storage and heat retention structure of FIG. 1A horizontally on the base F. Thermometers T1 and T2 (COMPACT THERMO manufactured by Anritsu)
ROGGER AM-8000K). The black putty material layer C was irradiated for 120 minutes with an infrared lamp heater L (beam lamp MX, manufactured by Toshiba, 110 V, 150 W) placed at a height H (55 cm) directly above the object A to be kept warm.
図３ＡはサーモメータＴ１、Ｔ２で測定した温度の推移を示したものである。ＲＴは室温（２５℃±１℃）を示す。図３Ａに示すように、黒色パテ材層Ｃの表面温度は照射開始後２０分程度で５５℃を超え、その後、緩やかに７０℃近くまで上昇する一方、白色パテ材層Ｂの裏面温度は照射開始後２０分程度経過して上昇しはじめ、その後、緩やかに５０℃近くまで上昇する。白色パテ材層Ｂの温度上昇は、黒色パテ材層Ｃに蓄熱された熱の一部が白色パテ材層Ｂに熱伝達したことによる。 FIG. 3A shows changes in temperature measured by thermometers T1 and T2. RT indicates room temperature (25°C±1°C). As shown in FIG. 3A, the surface temperature of the black putty material layer C exceeds 55°C in about 20 minutes after the start of irradiation, and then gradually rises to nearly 70°C, while the back surface temperature of the white putty material layer B increases. The temperature starts to rise about 20 minutes after the start, and then gradually rises to nearly 50°C. The temperature increase in the white putty material layer B is due to a portion of the heat stored in the black putty material layer C being transferred to the white putty material layer B.
このように白色パテ材層Ｂの裏面温度が５０℃近くまで上昇するので、被保温体Ａからの放熱を抑制することができ、また白色パテ材層Ｂで被保温体Ａから外側に向かう放熱を反射・抑制することもできるから、被保温体Ａを効果的に保温することができる。このように、本考案の蓄熱保温構造によれば、太陽熱などの外部の熱を被保温体Ａの保温に積極的に役立てることができる。 Since the temperature of the back surface of the white putty material layer B rises to nearly 50°C, it is possible to suppress the heat radiation from the heat-insulating object A, and the white putty material layer B dissipates heat outward from the heat-insulating object A. Since the heat can be reflected and suppressed, the body A to be kept warm can be kept warm effectively. In this way, according to the heat storage and heat retention structure of the present invention, external heat such as solar heat can be actively used to keep the body A to be kept warm.
図３Ｂは白色パテ材層Ｂと黒色パテ材層Ｃを上下反対に入れ替えた比較例１の保温効果を示すグラフである。この図３Ｂから、白色パテ材層Ｂと黒色パテ材層Ｃとも照射開始後１０分以降はほとんど温度上昇がなく、白色パテ材層Ｂは約４０℃、黒色パテ材層Ｃは約３０℃で一定であることがわかる。つまり、赤外線ランプヒータＬの熱が白色パテ材層Ｂで大部分反射されるため、白色パテ材層Ｂの内側に熱が蓄積されないのである。これでは太陽熱などの外部の熱を被保温体Ａの保温に積極的に役立てることはできない。 FIG. 3B is a graph showing the heat retention effect of Comparative Example 1 in which the white putty material layer B and the black putty material layer C were exchanged upside down. From FIG. 3B, there is almost no temperature rise in both white putty material layer B and black putty material layer C after 10 minutes after the start of irradiation, with white putty material layer B at about 40°C and black putty material layer C at about 30°C. It can be seen that it is constant. In other words, since most of the heat from the infrared lamp heater L is reflected by the white putty material layer B, no heat is accumulated inside the white putty material layer B. In this case, external heat such as solar heat cannot be actively used to keep the body A to be kept warm.
図３Ｃと図３Ｄは、厚さ５．０ｃｍと厚さ２．５ｃｍの発泡スチロール層Ｄ（ＦＶ５０）を図１Ｃのように被保温体Ａに装着した比較例２の保温効果を示すグラフであって、この比較例２でも図３Ｂとほぼ同じ結果になった。したがって、従来の発泡スチロール製の断熱カバーでは太陽熱などの外部の熱を被保温体Ａの保温に積極的に役立てることができないのである。 FIGS. 3C and 3D are graphs showing the heat retention effect of Comparative Example 2, in which a Styrofoam layer D (FV50) with a thickness of 5.0 cm and a thickness of 2.5 cm was attached to the heat insulation target A as shown in FIG. 1C. , Comparative Example 2 also gave almost the same results as FIG. 3B. Therefore, the conventional heat insulating cover made of polystyrene foam cannot actively utilize external heat such as solar heat to keep the body A to be kept warm.
なお、図１Ｄの参考例についてもサーモメータＴ１、Ｔ２で温度の推移を測定したが、黒色パテ材層Ｅの表面温度が図３Ａと同様に上昇するのに対して、黒色パテ材層Ｅの裏面温度は図３Ａの白色パテ材層Ｂの裏面温度（破線）の半分程度までしか上昇しなかった。また図１Ｄは黒色パテ材層Ｅの裏側に白色パテ材層がないので、被保温体Ａから外側に向かう放熱を反射・抑制することができず、被保温体Ａを効果的に保温することができない。したがって、黒色パテ材層Ｅの裏面温度が図３Ａの白色パテ材層Ｂの裏面温度と同等程度に上昇したとしても、被保温体Ａの保温効果は図１Ｄの参考例より図１Ａの実施形態の方が良好になる。 In addition, the temperature transition was also measured using thermometers T1 and T2 for the reference example in FIG. The back surface temperature rose only to about half of the back surface temperature (broken line) of the white putty material layer B in FIG. 3A. Furthermore, in FIG. 1D, since there is no white putty material layer on the back side of the black putty material layer E, it is not possible to reflect or suppress the heat dissipation from the heat-insulating object A toward the outside, and it is not possible to effectively insulate the heat-insulating object A. I can't. Therefore, even if the back surface temperature of the black putty material layer E rises to the same degree as the back surface temperature of the white putty material layer B in FIG. 3A, the heat retention effect of the heat insulating object A is lower than that in the embodiment in FIG. 1A than in the reference example in FIG. 1D. is better.
以上、本考案の実施形態について説明したが、本考案は前記実施形態に限定されることなく種々の変形が可能である。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be modified in various ways.
