産業上の利用分野
本発明は、住宅などにおける太陽熱利用システムにおけ
る集蓄熱器に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat collector and storage device in a solar heat utilization system in a house or the like.
従来の技術
従来、住宅における太陽熱利用システムは、強制循環型
と自然循環型があった。どちらも、太陽熱を集熱する部
分と、蓄熱する部分に分かれており、強制循環型は熱媒
の搬送を強制循環ポンプで行い、自然循環型は熱媒の温
度差による自然対流で行なっていた。Conventional technology Conventionally, solar heat utilization systems for homes have been of forced circulation type or natural circulation type. Both types are divided into a part that collects solar heat and a part that stores heat.The forced circulation type uses a forced circulation pump to transport the heat medium, while the natural circulation type uses natural convection due to the temperature difference in the heat medium. .
強制循環型は第６図のように、集熱可能時に強制循環ポ
ンプ６２で送り管６３を通って、集熱部に熱媒を送り、
返り管６４で蓄熱部６５へ返り。As shown in FIG. 6, in the forced circulation type, when heat collection is possible, a forced circulation pump 62 sends the heat medium to the heat collection part through a feed pipe 63.
It returns to the heat storage section 65 through the return pipe 64.
集熱部６１で集熱された熱を蓄熱していた。蓄熱した熱
を負荷側への送り管６６と負荷側からの返り管６７で、
給湯や空調に利用していた。The heat collected by the heat collecting section 61 was stored. The stored heat is transferred to the load side through a feed pipe 66 and a return pipe 67 from the load side.
It was used for hot water supply and air conditioning.
また、自然循環型は第７ｒｘｉのように、集熱部７１で
集熱された熱により、集熱板７９付近の熱媒の温度が上
昇し、比重が小さくなり浮力が生じる。Further, in the natural circulation type, as in the seventh rxi, the heat collected by the heat collecting portion 71 increases the temperature of the heat medium near the heat collecting plate 79, and the specific gravity becomes smaller, resulting in buoyancy.
これにより、集熱部７１の上層部から蓄熱部７５への返
り管７４を通る流れが生じる。それと同時に、蓄熱部７
５からの送り管７３から流路７８を通って集熱部７１の
下層部にも同量が流れる。このように、集熱中は、比重
差による圧力差で対流が生じ、蓄熱部への熱移動が可能
となる。This causes a flow from the upper layer of the heat collecting section 71 to the heat storage section 75 through the return pipe 74. At the same time, the heat storage section 7
The same amount flows from the feed pipe 73 from 5 to the lower layer of the heat collecting section 71 through the flow path 78. In this way, during heat collection, convection occurs due to the pressure difference due to the difference in specific gravity, and heat transfer to the heat storage section becomes possible.
発明が解決しようとする問題点
従来の上記のようなシステムにおいて、まず強制循環型
のシステムでは、集熱部と蓄熱部の位置は自由であるが
太陽熱を集熱するのに熱媒の搬送動力を必要とし、必ず
しも省エネルギーのシステムではない、また、自然循環
式のシステムは、集熱時は動力を必要とせず省エネルギ
ーではあるが、日射が終了し、大気に対しての放熱が始
まると、集熱時とは逆方向の流れが生じ、蓄熱部の熱を
放熱するように働く。Problems to be Solved by the Invention In the conventional systems as described above, firstly, in forced circulation systems, the positions of the heat collecting part and the heat storage part are free, but the transport power of the heat medium is required to collect solar heat. In addition, natural circulation systems do not require power when collecting heat and are energy saving, but once the solar radiation ends and heat radiation to the atmosphere begins, the natural circulation system A flow occurs in the opposite direction to when it is hot, and works to radiate heat from the heat storage area.
これを阻止しようとすると、第３図のように蓄熱部５は
集熱部１の上方に設置しなければならない。To prevent this, the heat storage section 5 must be installed above the heat collection section 1 as shown in FIG.
建物への設置を考えた場合、蓄熱部、と集熱部は一体化
することが、意匠上の大きな訴求点となるが、従来の自
然循環式では、これが、不可能であった。When considering installation in a building, a major design appeal is to integrate the heat storage section and the heat collection section, but this was not possible with conventional natural circulation systems.
本発明は、これらの問題点を解決し、搬送動力を必要と
せず省エネルギーで、なおかつ建物に対して納まりのい
い太陽熱利用システムを提供しようとするものである。The present invention aims to solve these problems and provide a solar heat utilization system that does not require transport power, is energy saving, and can be easily accommodated in buildings.
問題点を解決するための手段
この目的を達成するために、集蓄熱器の蓄熱槽内部に断
熱性のある仕切りを設置し、その上方と下方に開口部を
設け、下方の開口部に、仕切りと集熱板の闇に設置され
た形状記憶合金で開閉する弁を設置する。また、仕切ら
れた二つの空間を集熱部と蓄熱部にわけ、仕切りの位置
を集熱部側に寄せることにより集熱部の熱容量を蓄熱部
の熱容量より小さくする。Means for solving the problem In order to achieve this objective, a heat insulating partition is installed inside the heat storage tank of the heat collector, openings are provided above and below the partition, and a partition is placed in the bottom opening. A valve that opens and closes using a shape memory alloy is installed in the darkness of the heat collecting plate. Furthermore, by dividing the two partitioned spaces into a heat collecting section and a heat storage section, and moving the partition closer to the heat collecting section, the heat capacity of the heat collecting section is made smaller than that of the heat storage section.
作用
これにより、集熱中は搬送動力を必要とせず集熱部から
蓄熱部への熱移動が可能となり、又、集熱部の熱容量が
小さいため、仕切りが無い場合と比較して効率が良く、
夜間の放熱が少なく、なおかつ建物に対して納まりのい
い太陽熱利用システムを提供しようとするものである。As a result, during heat collection, heat can be transferred from the heat collection part to the heat storage part without the need for conveyance power, and since the heat capacity of the heat collection part is small, it is more efficient than when there is no partition.
The objective is to provide a solar heat utilization system that radiates less heat during the night and that can be easily accommodated in buildings.

A heat storage tank filled with water is placed in contact with the back side of the heat collecting plate 9. This liquid may be an antifreeze solution to prevent freezing.

ー１５を設ける。この図の弁は開いた状態である。A partition 1 having heat insulation properties is provided inside the heat storage tank near the heat collecting plate 9.
1 will be provided. This partition 11 divides the heat storage tank into a heat collection section 1 and a heat storage section 5, and has openings at the top and bottom, and a valve 12 is installed in the opening at the bottom. The shape memory alloy 13 is installed above the opening at the bottom of the heat collecting section 1 and connected to the valve 12 . This shape memory alloy undergoes memory treatment in a flexed state, and uses a compression coil spring that contracts at low temperatures and expands at high temperatures. It is made of Tl-N1 alloy and has a hysteresis of 5 degrees, with a valve opening temperature of 30°C and a closing temperature of 25°C. If you want to collect heat at a low temperature and use it every day, set these temperature settings lower than the above temperature. If you need a high temperature, increase the hysteresis and set each temperature higher. do. To utilize the heat storage section, a heat exchanger 16 is installed in the heat storage section 5, and a feed pipe 6 to the load and a return pipe 7 from the load are connected. A detailed sectional view of the lower part of the heat collector is shown in Figure 2. Valve 12 is 1
It is connected to 1. Further, a stopper 15 is provided at the bottom of the opening. The valve in this figure is in the open position.

押し、下方の開口部が開放となる。このときの流れを第
３図に示す。Hereinafter, the operation of the heat collector and storage device of the present invention will be explained. At night, the temperature of the heat collecting section 1 drops to near the outside air temperature due to radiation into the atmosphere. Therefore, the temperature near the shape memory alloy 13 is lower than the set value of 25°C, and as it contracts as shown in Fig. 1 and closes the valve 12t, water does not flow from the heat collecting section 1 to the heat storage section 5. When very low solar radiation starts, the heat collecting plate 9 collects heat. At this time, the temperature of the water near the heat collecting plate 9 in the heat collecting section 1 rises and its specific gravity decreases, creating a pressure difference and generating a flow flowing through the heat collecting section 1 from the bottom to the top. With this flow, the temperature near the shape memory alloy 13 increases. When the ambient temperature rises to 30° C., the temperature at which the shape memory alloy 13 stretches, the shape memory alloy 13 stretches and pushes the valve 12, opening the lower opening, as shown in FIG. The flow at this time is shown in FIG.
開放となった当初は蓄熱部５の下層部の低温度の水が流
れこんでくるため、一時的に形状記憶合金１３付近の温

、形状記憶合金１３は下部の開口部より上方に設置して
いるため、蓄熱部５からの水は加熱されて形状記憶合金
１３付近に達する。このため一時的な温度低下は５ ｄ
ｅｇ以上になりにくい。When the heat storage section 5 is first opened, low-temperature water from the lower layer of the heat storage section 5 flows in, so that the temperature near the shape memory alloy 13 temporarily decreases. Hunting of the shape memory alloy 13 is prevented by the hysteresis of 5 degrees of the set temperature. Further, since the shape memory alloy 13 is installed above the opening at the bottom, water from the heat storage section 5 is heated and reaches the vicinity of the shape memory alloy 13. Therefore, the temporary temperature drop is 5 d
It is difficult to become more than EG.
弁１２が開となったことにより、集熱部１の中で循環し
ていた流れが、蓄熱部５までまわり、蓄熱部５を加熱し
ていく、これにより、蓄熱部５に、太陽熱が蓄えられて
いく、また、集熱部１から蓄熱部５への流れの速さは、
集熱部１の熱容量が小さいほど、温度上昇が大きくなり
、比重差が大きくなるため、流れも速くなる。これによ
り、集熱板９付近の熱伝達が促進され効率が上がる。When the valve 12 is opened, the flow circulating in the heat collecting section 1 reaches the heat storage section 5 and heats the heat storage section 5. As a result, solar heat is stored in the heat storage section 5. Also, the speed of the flow from the heat collecting section 1 to the heat storage section 5 is
The smaller the heat capacity of the heat collecting part 1, the larger the temperature rise, the larger the difference in specific gravity, and the faster the flow. This promotes heat transfer near the heat collecting plate 9 and increases efficiency.
一方、集熱が終わると、集熱板９が大気への放射で冷や
され集熱部１の中を冷却された水が上方から下方へ流れ
、再び形状記憶合金１３の周辺の温度が２５℃以下に低
下し、第１図のように形状記憶合金１３が縮み弁１２を
動かす、ストッパー１５と、弁１２で下方の開口部は閉
じられる。さらに、冷却がすすむと、第４図のように集
熱部１内の水のみが循環し蓄熱部５の温度低下は防止さ
れる。仕切り１１は、断熱性があるため、仕切り１１を
通じての伝達による熱損失は少ない。On the other hand, when the heat collection is finished, the heat collection plate 9 is cooled by radiation to the atmosphere, and the cooled water inside the heat collection part 1 flows from above to below, and the temperature around the shape memory alloy 13 increases to 25°C again. The shape memory alloy 13 contracts and moves the valve 12 as shown in FIG. 1, and the lower opening is closed by the stopper 15 and the valve 12. Further, when the cooling progresses, only the water in the heat collecting section 1 is circulated as shown in FIG. 4, and the temperature of the heat storage section 5 is prevented from decreasing. Since the partition 11 has heat insulating properties, heat loss due to transmission through the partition 11 is small.

交換器２９に送るシステム例である。An example of using the stored heat in this way is shown in Figure 1. Put the heat exchanger 16 directly into the heat storage section 5,
It exchanges heat with the water in the heat storage section 5. The load is sent through a feed pipe 6 and returned through a return pipe 7. We will also give an example of the application of this heat collector to an air conditioning system. Figure 5 shows
In a heat pump air conditioner consisting of a compressor 24, a four-way valve 25, a condenser 27, an expansion valve 28, and an evaporator 26, a circulation pump is installed to prevent a decrease in heating capacity and defrost operation at low outside temperatures. 30 is an example of a system in which water in the heat storage section 5 is directly sent to the preheating heat exchanger 29.

In winter, when the outside temperature is low, heating capacity decreases and frost builds up on the evaporator 21. At this time, in order to perform defrosting operation, the refrigeration cycle must be reversed, and conventionally heating operation was not possible.

The temperature of the outside air flowing into the evaporator 26 increases, preventing a decrease in heating capacity and increasing the efficiency of the entire system.
