Description
【発明の詳細な説明】 この発明は太陽熱給湯蓄熱装置に関するものである。[Detailed description of the invention] The present invention relates to a solar water heating and storage device.
飲用可能な清潔な高温湯を供給できる従来の太陽熱給湯
蓄熱装置を第１図に示す。FIG. 1 shows a conventional solar hot water storage device that can supply clean, hot water that is drinkable.
図にお（・て、太陽熱コレクタ１内で加熱された熱媒体

クタ１に還元される。In the figure, the temperature of the heat medium heated in the solar collector 1 is detected by the temperature sensor 2, and the temperature is higher than the temperature of the hot water in the hot water tank 4 detected by the temperature sensor 3. , the heat medium heated by the solar collector 1 is transferred to the heat exchanger 6 in the hot water tank 4 by the solenoid valve 5.
After heating the hot water, it is returned to the solar collector 1 via a solenoid valve I.

暖房用蓄熱槽９内の暖房用熱媒体の温度より高〜・場合
には、熱媒体が電磁弁１０を経て暖房用蓄熱槽９内の熱
交換器１１へ送られる。If the temperature of the heat medium heated in the solar collector 1 is lower than the temperature in the hot water tank 4 and higher than the temperature of the heating heat medium in the heating heat storage tank 9 detected by the temperature sensor 8, The heat medium is sent to the heat exchanger 11 in the heating heat storage tank 9 via the electromagnetic valve 10.
そして、太陽熱コレクタ１で加熱された熱媒体の温度が
暖房用蓄熱槽９内の暖房用熱媒体の温度以下のときは熱
媒体が熱交換器６，１１へ送られず太陽熱コレクタ１で
さらに加熱されるようになってＬ・る。When the temperature of the heat medium heated by the solar heat collector 1 is lower than the temperature of the heating heat medium in the heating heat storage tank 9, the heat medium is not sent to the heat exchangers 6 and 11 and is further heated by the solar heat collector 1. L・ru started to be treated.

・ため熱効率が悪かった。Note that 4a is distane. A solar hot water heat storage device having such a structure does not directly exchange heat (using heat exchangers 6 and 11), but also uses the heat exchanger 6 in the hot water tank 4 to finish the heat exchange. The heated heat medium is further led to the heat exchanger 11 for heat exchange to a temperature of °C.
・Thermal efficiency was poor.
この欠点を解消するために第２図に示すような太陽熱給
湯蓄熱装置が提案された。In order to solve this drawback, a solar hot water storage device as shown in FIG. 2 was proposed.
この装置は、熱交換槽１２を新たに設は太陽熱コレクタ

槽１４の温湯を熱交換器１５に自然循環させて加熱する
。In this device, a heat exchange tank 12 is newly installed, and when the temperature of the heat medium heated by the solar heat collector 13 is higher than the temperature of the heat medium in the heat exchange tank 12, the heat medium is transferred from the solar heat collector 13 to the heat exchange tank 12. This heat exchange tank 12
A heat exchanger 15 communicating with the hot water supply tank 14 is disposed inside the hot water supply tank 14, and hot water from the hot water supply tank 14 is naturally circulated through the heat exchanger 15 to be heated.

高Ｌ・場合には、太陽熱コレクタ１３から熱媒体が暖房
用蓄熱槽１６内へ直接送られるようになってＬ・る。In addition, when the temperature of the heat medium heated by the solar heat collector 13 is lower than the temperature of the heat medium in the heat exchange tank 12 and higher than the temperature of the heat medium in the heating heat storage tank 16, In this case, the heat medium is directly sent from the solar heat collector 13 into the heating heat storage tank 16.
そのほかの部分は第１図と同じである。この装置は、熱
交換槽１２が小さく設定されかつ熱交換器を用いること
なく直接熱交換をするため熱効率が向上する。Other parts are the same as in Figure 1. This device improves thermal efficiency because the heat exchange tank 12 is set small and heat exchange is performed directly without using a heat exchanger.
ところが、このようにすると、熱交換槽１２を新たに設
けなげればならなＬ・ためコストが高くなるという問題
が生じた。However, in this case, a problem arises in that a new heat exchange tank 12 must be provided, resulting in increased costs.
したがって、この発明の目的は、熱効率がよくしかもコ
ストが高くなることのなＬ・太陽熱給湯蓄熱装置を提供
することである。Therefore, an object of the present invention is to provide an L/solar hot water heating and storage device that has good thermal efficiency and does not increase cost.
この発明の一実施例の構成図を第３図に示す。A configuration diagram of an embodiment of the present invention is shown in FIG.

熱槽９内に直接供給するようにしたことである。The difference between this device and the device shown in FIG. 1 is that a discharge pipe 20 of a heat exchanger 6 disposed in a hot water tank 4 is connected to a branch pipe that connects a temperature sensor 21 and a heat exchanger 6 to a heating heat storage tank 9. 22 and a solenoid valve 23 that switches the flow path of the heat medium flowing through the discharge pipe 20 in response to the temperature sensor 21, so that the temperature of the heat medium that has finished heat exchange in the heat exchanger 6 is adjusted to the heating heat storage tank 9.
When the temperature is higher than the temperature of the heat medium inside the tank, the solenoid valve 23 is used to send the heat medium from the heat exchanger 6 to the heating heat storage tank 9. The idea was to supply it directly to the inside.
なお、２４ａは給湯用カラン、２５ｂはポンプである。Note that 24a is a hot water supply pot, and 25b is a pump.
このように構成した結果、給湯槽４内の熱交換器６で熱
交換を終えた熱媒体を有効に使用することができ、かつ
暖房用蓄熱槽９内の熱媒体を太陽熱コレクタ１によって
直接加熱できるため熱効率が極めてよくなる。As a result of this configuration, the heat medium that has undergone heat exchange in the heat exchanger 6 in the hot water tank 4 can be effectively used, and the heat medium in the heating heat storage tank 9 can be directly heated by the solar heat collector 1. As a result, thermal efficiency is extremely improved.

高温の温湯を供給できるとＬ・う効果をもつ。This embodiment has the same functions and effects as the above-mentioned embodiment, and also has an additional advantage of being able to supply high-temperature hot water by driving the electric heater 25 when sunlight is weak.
