Description

本発明は、日射の無い夜間や日射の少ない悪天候時にも使用を可能とする、電気ヒーターを内蔵する空気熱媒の太陽熱集熱装置に関するものである。  The present invention relates to a solar heat collecting apparatus of an air heating medium incorporating an electric heater that can be used at night when there is no solar radiation or in bad weather with little solar radiation.

従来の空気を媒体とする太陽熱集熱装置は、例えば、特開2002−340418公報の記載にあるように、多数孔からなる集熱板が箱型筐体内に配置されており、空気がこの集熱板の孔および表層を通過する際、太陽熱により加熱された集熱板から効率よく熱を吸収する構造になっている(特許文献1)。  In a conventional solar heat collecting apparatus using air as a medium, for example, as described in Japanese Patent Application Laid-Open No. 2002-340418, a heat collecting plate composed of a large number of holes is arranged in a box-shaped housing, and the air is collected in this box. When passing through the holes and the surface layer of the hot plate, the heat collecting plate efficiently absorbs heat from the heat collecting plate heated by solar heat (Patent Document 1).

また、特開2005−337615公報に記載の太陽熱集熱装置は、筐体内に蓄熱材を配備し、日射が少なくなった時の補助熱源として、空気の加熱時間を延長させる機能を有する構造である(特許文献2)。  Further, the solar heat collecting apparatus described in Japanese Patent Application Laid-Open No. 2005-337615 has a structure having a function of extending a heating time of air as an auxiliary heat source when a heat storage material is provided in a housing and solar radiation is reduced. (Patent Document 2).

さらに、実登3112663公報に記載の太陽熱集熱装置は、筐体内に蓄熱材と電気ヒーターを配備し、悪天候時や夜間でも空気を加熱できる構造のものである(特許文献3)。

しかしながら、上記特許文献1に記載の発明は、太陽熱のみを熱源としているため夜間や悪天候時には加熱できない。また、上記特許文献2に記載の発明は、日照時間が短い時に蓄熱量が十分確保できず加熱できる時間が短くなり、その結果、太陽熱以外の加熱機器を別途設備させる必要があった。さらに、上記特許文献3に記載の蓄熱材と電気ヒーターを内蔵したタイプでは、日射量の少ないとき、電気加熱によって空気と蓄熱材を同時に加熱することになり、本来暖めるべき空気への熱エネルギーの一部が蓄熱材を暖めることに使用され、エネルギーロスを招くという課題を有していた。  However, since the invention described in Patent Document 1 uses only solar heat as a heat source, it cannot be heated at night or in bad weather. Further, the invention described in the above-mentioned Patent Document 2 requires a sufficient amount of heat storage when the sunshine time is short, shortening the time for heating, and as a result, it is necessary to separately provide heating equipment other than solar heat. Furthermore, in the type having the built-in heat storage material and electric heater described in Patent Document 3, when the amount of solar radiation is small, the air and the heat storage material are simultaneously heated by electric heating, and the heat energy to the air to be originally warmed Some were used to warm the heat storage material, and had the problem of incurring energy loss.

太陽光に対して、多数孔を有した太陽熱集熱板3の背部に蓄熱性の高い無孔板4を配置することにより、多数孔を通過した太陽光も無孔板4で受け止め集熱することでき、太陽熱を効率よく集熱と蓄熱ができる。  By disposing the highly heat-retaining non-perforated plate 4 on the back of the solar heat collecting plate 3 having a large number of holes with respect to sunlight, the non-perforated plate 4 also receives and collects the sunlight that has passed through the large number of holes. The solar heat can be collected and stored efficiently.

無孔板4の背部に背部空間12を設ける。無孔板4も上部には、背部空間12に空気を搬送するための隙間を設ける。  A back space 12 is provided on the back of the non-perforated plate 4. A gap for conveying air to the back space 12 is also provided at the upper part of the non-perforated plate 4.

背部空間12の上方から筐体1の背部まで貫通する空気排出口9を設ける。  An air discharge port 9 penetrating from above the back space 12 to the back of the housing 1 is provided.

背部空間12内部の空気排出口9の上部に、空気流路調整用板7を配備、また下部には電気ヒーター6を配備する。  An air flow path adjusting plate 7 is provided above the air discharge port 9 inside the back space 12, and an electric heater 6 is provided below.

背部空間12の下方から筐体1の背部まで貫通する空気吸入口10を設け、太陽熱集熱装置外側の入口にシロッコファン等の送風機11を配備する。  An air suction port 10 penetrating from the lower part of the back space 12 to the back part of the housing 1 is provided, and a blower 11 such as a sirocco fan is provided at an entrance outside the solar heat collecting apparatus.

送風機11で太陽熱集熱装置に空気を押し込むことによって、装置内部の気圧は外気よりも高くなり、低温外気の侵入を防ぐ効果がある。  By pushing the air into the solar heat collecting device with the blower 11, the air pressure inside the device becomes higher than the outside air, and there is an effect of preventing the low temperature outside air from entering.

また、太陽熱集熱板3と無孔板4の下部に空気流路を切り替える為のクロスフローファン等の平面空気流を発生する送風装置8を配備する。  Moreover, the air blower 8 which generate | occur | produces planar airflows, such as a crossflow fan for switching an air flow path, is arrange | positioned in the lower part of the solar-heat collecting plate 3 and the non-porous board 4.

Air deprives the heat of the solar heat collecting plate 3, rises while raising the temperature, and is pushed out from the air outlet 9.

先述した空気流路調整用板7を配備することにより、太陽熱集熱装置内上方に昇温された空気が集まり停滞すること無く、空気排出口9から排出されるように最適な空気流路に導くことができる。  By arranging the air flow path adjusting plate 7 as described above, the air flow temperature is raised upward in the solar heat collecting apparatus so that the air flow is optimally discharged from the air discharge port 9 without stagnation. Can lead.

図3で示す実施例は、日射量が不十分の状態での太陽熱集熱装置の動作状態を示している。  The embodiment shown in FIG. 3 shows the operating state of the solar heat collecting apparatus in a state where the amount of solar radiation is insufficient.

太陽熱集熱板3と無孔板4の周辺気温を感知できるように取り付けられた温度センサー5で、太陽熱集熱状況を温度で感知し、所定の温度以下になったとき、下部に配備された送風装置8が停止し、透光板2と太陽熱集熱板3の間を流れようとする空気の抵抗となる。空気吸入口10から送り込まれた空気は、空気抵抗の少ない無孔板4の背部に設けられた背部空間12へ流路を変更させられる。同時に電気ヒーター6が稼動して背部空間12に流入した空気を加熱、昇温した空気が空気排出口9から押し出される。  The temperature sensor 5 attached so as to detect the ambient temperature of the solar heat collecting plate 3 and the non-porous plate 4 senses the solar heat collecting state by temperature, and when the temperature falls below a predetermined temperature, it is installed in the lower part. The air blower 8 stops and it becomes the resistance of the air which is going to flow between the translucent plate 2 and the solar heat collecting plate 3. The air sent from the air suction port 10 is changed in the flow path to the back space 12 provided on the back of the non-perforated plate 4 having a low air resistance. At the same time, the electric heater 6 is operated to heat the air flowing into the back space 12, and the heated air is pushed out from the air outlet 9.

背部空間12内の空気排出口9の上部に配備された空気流路調整用板7は、電気ヒーターで昇温した空気を所定の位置でせき止め、昇温した空気を空気排出口9へ導く。  The air flow path adjusting plate 7 disposed above the air discharge port 9 in the back space 12 blocks the air heated by the electric heater at a predetermined position and guides the heated air to the air discharge port 9.

断熱性の高い無孔板4で太陽熱集熱装置の前方と背部空間12を遮断することにより背部空間12を上昇する空気の熱が装置の前方へ熱伝導するのを防止し、結果、装置外部への放熱を防ぐ効果がある。By blocking the front of the solar heat collector and the back space 12 with the highly heat-insulating non-perforated plate 4, the heat of the air rising up the back space 12 is prevented from conducting heat to the front of the device. It has the effect of preventing heat dissipation.
