Description

本発明は、太陽熱利用システムに関する。   The present invention relates to a solar heat utilization system.

従来より種々の太陽熱利用システムが提供されているが、例えば、太陽熱を利用した給湯システムとして、熱媒循環回路に太陽熱集熱部とポンプと熱交換部とが介設され、ポンプを駆動することにより、太陽熱集熱部において循環回路内の熱媒を太陽熱で加温し、加温された熱媒の熱を熱交換部で貯湯槽内等の水に伝えて給湯用のお湯をつくるようになされた太陽熱利用給湯システムにおいて、日射検知器が備えられ、日射量が設定基準値以下であるときは、ポンプが停止状態となり、ポンプを駆動するための電力が節約されるようにしたものがある。
特開平１０−１８５３３２号公報 Various solar heat utilization systems have been provided so far. For example, as a hot water supply system using solar heat, a solar heat collection unit, a pump, and a heat exchange unit are interposed in a heat medium circulation circuit to drive the pump. Thus, the heating medium in the circulation circuit is heated by solar heat in the solar heat collecting part, and the heat of the heated heating medium is transmitted to the water in the hot water storage tank etc. in the heat exchange part to make hot water for hot water supply In the solar water heating system that has been made, a solar radiation detector is provided, and when the amount of solar radiation is less than a set reference value, the pump is stopped and power to drive the pump is saved. .
JP-A-10-185332

しかしながら、上記のようなシステムでは、日射量の基準値の設定のしかたによって、基準値を大きな値に設定すると、太陽熱集熱部で太陽熱を効率良く集熱することができるにもかかわらず、ポンプが停止して太陽熱を利用することができず、また、基準値を小さな値に設定すると、太陽熱集熱部における集熱効率が低いにもかかわらずポンプが駆動して電気を無駄に消費してしまうことから、太陽熱の効率の良い利用とポンプの節電効果の両方を満足する基準値に設定する必要があるが、そのような基準値では、得られる効果に限界がある。   However, in the system as described above, if the reference value is set to a large value by setting the reference value of the amount of solar radiation, the solar heat collecting unit can efficiently collect solar heat, but the pump Stops and solar heat cannot be used, and if the reference value is set to a small value, the pump is driven and wastes electricity even though the heat collection efficiency in the solar heat collection unit is low For this reason, it is necessary to set a reference value that satisfies both the efficient use of solar heat and the power saving effect of the pump, but such a reference value has a limit in the effect that can be obtained.

本発明は、上記のような問題点に鑑み、太陽熱の効率の良い利用と、ポンプ等の駆動源の消費エネルギー節約効果との両方を、より高いレベルで満足させることができる、太陽熱利用システムを提供することを課題とする。   In view of the above problems, the present invention provides a solar heat utilization system that can satisfy both the efficient use of solar heat and the energy saving effect of a drive source such as a pump at a higher level. The issue is to provide.

上記の課題は、流体通路部を備え、該通路部を通過する流体を太陽熱で加温する太陽熱集熱部と、
太陽熱集熱部の通路部入口に接続された流体送入管と、
太陽熱集熱部の通路部出口に接続された流体送出管と、
流体送入管側又は流体送出管側に設けられたポンプ等の駆動源と
が備えられ、駆動源の駆動により流体送入管から太陽熱集熱部の流体通路部に送り込まれた流体を太陽熱で加温し、流体送出管に送り出すようになされている太陽熱利用システムにおいて、
日射量を検知する日射センサーと、
該日射センサーが検知した日射量に基づき、日射量が多いとき太陽熱集熱部の流体通路部を通過する流体の流量を大きくし、日射量が少ないとき太陽熱集熱部の流体通路部を通過する流体の流量を小さくするように、駆動源の駆動力の大きさの可変制御を行う制御部と
が備えられていることを特徴とする太陽熱利用システムによって解決される。 Said subject is provided with a fluid passage part, a solar heat collecting part which heats fluid which passes through this passage part with solar heat,
A fluid inlet pipe connected to the passage inlet of the solar heat collector,
A fluid delivery pipe connected to the exit of the passage of the solar heat collector,
And a drive source such as a pump provided on the fluid feed pipe side or the fluid feed pipe side, and the fluid sent from the fluid feed pipe to the fluid passage section of the solar heat collecting section by driving the drive source is solar heat. In the solar heat utilization system that is heated and sent to the fluid delivery pipe,
A solar radiation sensor that detects the amount of solar radiation;
Based on the amount of solar radiation detected by the solar radiation sensor, when the amount of solar radiation is large, the flow rate of the fluid passing through the fluid passage portion of the solar heat collecting portion is increased, and when the amount of solar radiation is small, the fluid passage portion of the solar heat collecting portion is passed. This is solved by a solar heat utilization system including a control unit that performs variable control of the magnitude of the driving force of the driving source so as to reduce the flow rate of the fluid.

このシステムでは、日射量が多いときには、太陽熱集熱部の流体通路部を通過する流体の流量が大きくなって、駆動源で消費される駆動エネルギーが大きくなるが、駆動源で消費される駆動エネルギーに見合った効率の良い太陽熱の利用が行われ、また、日射量が少ないときは、太陽熱集熱部の流体通路部を通過する流体の流量が小さくなって、駆動源で消費される駆動エネルギーが節約されると共に、駆動源で消費される駆動エネルギーに見合った効率の良い太陽熱の利用が行われ、こうして、太陽熱の効率の良い利用と、ポンプ等の駆動源の消費エネルギー節約効果との両方を、より高いレベルで満足させることができる。   In this system, when the amount of solar radiation is large, the flow rate of the fluid passing through the fluid passage portion of the solar heat collector increases, and the drive energy consumed by the drive source increases, but the drive energy consumed by the drive source increases. When the solar heat is used efficiently and the amount of solar radiation is small, the flow rate of the fluid passing through the fluid passage of the solar heat collector is reduced, and the drive energy consumed by the drive source is reduced. In addition to saving, efficient use of solar heat corresponding to the drive energy consumed by the drive source is performed, and thus both the efficient use of solar heat and the energy consumption saving effect of the drive source such as a pump are achieved. Can be satisfied at a higher level.

即ち、従来のように駆動源を入切制御するのに対して、本発明のシステムでは、駆動源の駆動力の大きさが日射量に応じて可変制御されるようになされているものであり、この可変制御によって、太陽熱の効率の良い利用と、ポンプ等の駆動源の消費エネルギー節約効果との両方を、より高いレベルで満足させるようにするものである。   That is, on the other hand, the driving source is controlled to be turned on and off as in the prior art, but in the system of the present invention, the driving force of the driving source is variably controlled according to the amount of solar radiation. By this variable control, both the efficient use of solar heat and the energy saving effect of the driving source such as a pump are satisfied at a higher level.

また、上記の課題は、流体通路部を備え、該通路部を通過する流体を太陽熱で加温する太陽熱集熱部と、
太陽熱集熱部の通路部入口に接続された流体送入管と、
太陽熱集熱部の通路部出口に接続された流体送出管と、
流体送入管側又は流体送出管側に設けられたポンプ等の駆動源と
が備えられ、駆動源の駆動により流体送入管から太陽熱集熱部の流体通路部に送り込まれた流体を太陽熱で加温し、流体送出管に送り出すようになされている太陽熱利用システムにおいて、
太陽光発電部が備えられ、前記駆動源は、該太陽光発電部で発電した電気で駆動するようになされており、太陽光発電部の発電量に応じて、発電量が多いとき太陽熱集熱部の流体通路部を通過する流体の流量を大きくし、発電量が少ないとき太陽熱集熱部の流体通路部を通過する流体の流量を小さくするように、駆動力の大きさが可変制御されるようになされていることを特徴とする太陽熱利用システムによって解決される。 Moreover, said subject is provided with the fluid channel | path part, The solar-heat collection part which heats the fluid which passes this channel | path part with a solar heat,
A fluid inlet pipe connected to the passage inlet of the solar heat collector,
A fluid delivery pipe connected to the exit of the passage of the solar heat collector,
And a drive source such as a pump provided on the fluid feed pipe side or the fluid feed pipe side, and the fluid sent from the fluid feed pipe to the fluid passage section of the solar heat collecting section by driving the drive source is solar heat. In the solar heat utilization system that is heated and sent to the fluid delivery pipe,
A solar power generation unit is provided, and the driving source is configured to be driven by electricity generated by the solar power generation unit, and according to the power generation amount of the solar power generation unit, when the amount of power generation is large, solar heat collection The magnitude of the driving force is variably controlled so that the flow rate of the fluid passing through the fluid passage portion of the solar heat collecting portion is reduced when the flow rate of the fluid passing through the fluid passage portion is increased and the amount of power generation is small. It is solved by a solar heat utilization system characterized by being made.

このシステムにおいても、同様に、駆動源の駆動力の大きさが日射量に応じて可変制御されるようになされているものであり、この可変制御によって、太陽熱の効率の良い利用と、ポンプ等の駆動源の消費エネルギー節約効果との両方を、より高いレベルで満足させることができる。   Similarly, in this system, the magnitude of the driving force of the driving source is variably controlled in accordance with the amount of solar radiation. With this variable control, efficient use of solar heat, pumps, etc. Both of the energy saving effects of the driving source can be satisfied at a higher level.

のみならず、太陽熱集熱部での集熱力と、太陽光発電部での発電力とは、日射量との関係で、いずれも、日射量が多いときは大きくなり、日射量が少ないと小さくなる関係にあり、太陽光発電部での発電と日射との関係を利用して、駆動源の駆動力を、簡素な機構でうまい具合に可変制御することができる。   Not only that, the heat collecting power in the solar heat collector and the power generated in the solar power generator are related to the amount of solar radiation, and both increase when the amount of solar radiation is large, and decrease when the amount of solar radiation is small. Using the relationship between power generation and solar radiation in the solar power generation unit, the driving force of the driving source can be variably controlled with a simple mechanism.

もちろん、駆動源は、太陽光発電部で発電した電気で駆動するようになされているので、商用電源からの電気の使用量を抑えることができて、電気代を節約することができる。   Of course, since the drive source is driven by electricity generated by the solar power generation unit, the amount of electricity used from the commercial power source can be suppressed, and the electricity bill can be saved.

本発明は、以上のとおりのものであるから、太陽熱の効率の良い利用と、ポンプ等の駆動源の消費エネルギー節約効果との両方を、より高いレベルで満足させることができる。   Since the present invention is as described above, it is possible to satisfy both the efficient use of solar heat and the energy saving effect of a driving source such as a pump at a higher level.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１に示す第１実施形態の太陽熱利用システムは、給湯システムに適用した場合のもので、該太陽熱利用給湯システムは、水循環回路１に太陽熱集熱部２と、駆動源としてのポンプＰと、熱交換部４とが介設され、ポンプＰを駆動することにより、太陽熱集熱部２において循環回路１内の流体としての水を太陽熱で加温し、加温された水の熱を熱交換部４で貯湯槽５内の水に伝えて貯湯槽５の水を加温するようになされたもので、該水循環回路１によって、太陽熱集熱部２の流体通路部２ｃの入口２ａに接続された流体送入管部１ａと、同出口２ｂに接続された流体送出管部１ｂとが形成されている。   The solar heat utilization system of the first embodiment shown in FIG. 1 is applied to a hot water supply system. The solar heat utilization hot water supply system includes a solar heat collecting unit 2 in a water circulation circuit 1, a pump P as a drive source, By interfacing with the heat exchanging unit 4 and driving the pump P, the solar heat collecting unit 2 heats water as a fluid in the circulation circuit 1 with solar heat, and exchanges heat of the heated water. The water is transferred to the water in the hot water tank 5 by the section 4 to heat the water in the hot water tank 5, and is connected to the inlet 2a of the fluid passage 2c of the solar heat collecting section 2 by the water circulation circuit 1. In addition, a fluid delivery pipe section 1a and a fluid delivery pipe section 1b connected to the outlet 2b are formed.

太陽熱集熱部２は、例えば、シリカエアロゲル等の透明多孔質断熱材と選択吸収膜とを組み合わせて選択吸収膜に集熱された太陽熱を流体通路部２ｃ内の水に伝えるようになされたものなどが用いられるが、特に制限はなく、各種構造の太陽熱集熱部が用いられてよい。   The solar heat collecting part 2 is configured to transmit solar heat collected by the selective absorption film to the water in the fluid passage part 2c by combining a transparent porous heat insulating material such as silica airgel and the selective absorption film, for example. However, there is no particular limitation, and a solar heat collecting part having various structures may be used.

なお、貯湯槽５には水道管８と給湯管９が接続され、１３は混合弁で、該混合弁１３により、貯湯槽５で沸かされた高温水と水道水とが混合されて所定の温度の高温水に調整され、利用側には、この高温水と水道水とが混合されて利用温度の温水が供給されるようになされている。１０は膨張タンク、１１…は開閉バルブ、１２は逆止弁である。   A water pipe 8 and a hot water pipe 9 are connected to the hot water tank 5, 13 is a mixing valve, and the mixing valve 13 mixes hot water boiled in the hot water tank 5 with tap water to a predetermined temperature. The high-temperature water is adjusted, and the high-temperature water and tap water are mixed and supplied to the use side. 10 is an expansion tank, 11... Is an on-off valve, and 12 is a check valve.

そして、上記のシステムには、日射量を検知する日射センサー１４と、制御部１５とが備えられ、制御部１５は、日射センサー１４で検知された日射量に基づき、日射量が多いとき太陽熱集熱部２の流体通路部２ｃを通過する水の流量を大きくし、日射量が少ないとき太陽熱集熱部２の流体通路部２ｃを通過する水の流量を小さくすべく、ポンプＰの駆動力の大きさの可変制御を行うようになされている。なお、日射センサーとして、制御部の機能を果たすことができる日射計を用いるときは、日射計とは別に制御部を備えさせる必要はない。   The system includes a solar radiation sensor 14 that detects the amount of solar radiation, and a control unit 15. The control unit 15 collects solar heat when the solar radiation amount is large based on the amount of solar radiation detected by the solar radiation sensor 14. In order to increase the flow rate of water passing through the fluid passage portion 2c of the heat portion 2 and reduce the flow rate of water passing through the fluid passage portion 2c of the solar heat collecting portion 2 when the amount of solar radiation is small, the driving force of the pump P Variable size control is performed. In addition, when using the pyranometer which can fulfill | perform the function of a control part as a solar radiation sensor, it is not necessary to provide a control part separately from a pyranometer.

上記の太陽熱利用システムでは、日射量が多いときには、それを日射センサー１４が検知し、制御部１５による制御により、太陽熱集熱部２の流体通路部２ｃを通過する水の流量が大きくなって、ポンプＰで消費される駆動エネルギーが大きくなるが、ポンプＰで消費される電気エネルギーに見合った効率の良い太陽熱の利用が行われる。また、日射量が少ないときは、太陽熱集熱部２の流体通路部２ｃを通過する水の流量が小さくなって、ポンプＰで消費される駆動エネルギーが節約されると共に、ポンプＰで消費される電気エネルギーに見合った効率の良い太陽熱の利用が行われる。こうして、太陽熱の効率の良い利用と、ポンプＰの消費電気エネルギー節約効果との両方が、より高いレベルで満足される。   In the solar heat utilization system, when the amount of solar radiation is large, the solar radiation sensor 14 detects it, and the flow rate of water passing through the fluid passage part 2c of the solar heat collecting part 2 is increased by the control by the control part 15, The driving energy consumed by the pump P increases, but efficient use of solar heat corresponding to the electric energy consumed by the pump P is performed. Further, when the amount of solar radiation is small, the flow rate of water passing through the fluid passage portion 2c of the solar heat collecting portion 2 is reduced, so that driving energy consumed by the pump P is saved and consumed by the pump P. Efficient use of solar heat in accordance with electric energy is performed. Thus, both the efficient use of solar heat and the power consumption saving effect of the pump P are satisfied at a higher level.

なお、日射センサーは、日射量ないしは日射強度を検知することができるものであればよく、本来の日射計を用いたものからなっていてもよいし、温度センサーを用いたものからなっていてもよいし、光センサーを用いたものからなってもよいし、制限はない。   The solar radiation sensor is not limited as long as it can detect the amount of solar radiation or the intensity of solar radiation, and it may be composed of an original solar radiation meter or a temperature sensor. It may be a thing using an optical sensor, and there is no restriction | limiting.

図２に示す第２実施形態の太陽熱利用システムは、第１実施形態のシステムにおいて、日射計に替え、太陽光発電部１６を備えさせたもので、ポンプＰは、太陽光発電部１６で発電した電気で駆動するようになされており、太陽光発電部１６の発電量に応じて、発電量が多いとき、ポンプＰの駆動力が高まって太陽熱集熱部２の流体通路部を通過する水の流量を大きくし、発電量が少ないときポンプＰの駆動力が低下して太陽熱集熱部２の流体通路部を通過する水の流量を小さくするように、駆動力の大きさが可変制御されるようになされている。   The solar heat utilization system according to the second embodiment shown in FIG. 2 is the same as the system according to the first embodiment except that the solar power generation unit 16 is provided instead of the solar radiation meter. When the power generation amount is large according to the power generation amount of the solar power generation unit 16, the driving force of the pump P is increased and the water passing through the fluid passage portion of the solar heat collection unit 2 is driven. The driving force is variably controlled so that the driving force of the pump P decreases and the flow rate of the water passing through the fluid passage part of the solar heat collecting part 2 decreases when the power generation amount is small. It is made so that.

このシステムにおいても、第１実施形態のシステムと同様に、ポンプＰの駆動力の大きさが日射量に応じて可変制御されるようになされているので、この可変制御によって、太陽熱の効率の良い利用と、ポンプ等の駆動源の消費エネルギー節約効果との両方を、より高いレベルで満足させることができる。   Also in this system, similarly to the system of the first embodiment, the magnitude of the driving force of the pump P is variably controlled in accordance with the amount of solar radiation. Both the utilization and the energy saving effect of the driving source such as a pump can be satisfied at a higher level.

そして、本実施形態では、ポンプＰが、太陽光発電部１６で発電した電気で駆動するようになされているので、商用電源からの電気の使用量を抑えることができて、電気代を節約することができるのはもちろん、太陽熱集熱部２での集熱力も、太陽光発電部１６での発電力も、いずれも日射量との関係で、日射量が多いときは大きくなり、日射量が少ないと小さくなる関係を利用してポンプＰの駆動力の可変制御が行われるようになされているものであるから、ポンプＰの駆動力を簡素な制御機構でうまい具合に可変制御することができる。   In this embodiment, since the pump P is driven by the electricity generated by the solar power generation unit 16, the amount of electricity used from the commercial power source can be suppressed, and the electricity bill can be saved. Of course, both the heat collecting power in the solar heat collecting section 2 and the power generated in the solar power generation section 16 are large when the amount of solar radiation is large and the amount of solar radiation is small due to the amount of solar radiation. Thus, the variable control of the driving force of the pump P is performed using the relationship that becomes smaller, so that the driving force of the pump P can be variably controlled with a simple control mechanism.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、上記の実施形態では、水循環回路１に太陽熱集熱部２とポンプＰと熱交換部４とを介設し、太陽熱によって熱交換部４で貯湯槽５内の水を沸かせる循環式の給湯システムに適用した場合を示したが、水循環回路に太陽熱集熱部とポンプと貯湯槽とを介設し、貯湯槽内の水を水循環回路内で循環させて太陽熱で加温していく循環式の太陽熱利用給湯システムに適用することも可能であるし、また、非循環式の太陽熱利用給湯システムに適用することも可能であるし、また、給湯、暖房に限らず、各種の太陽熱利用システムに適用することも可能である。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, a solar heat collecting unit 2, a pump P, and a heat exchanging unit 4 are provided in the water circulation circuit 1, and the circulating type of boiling water in the hot water tank 5 by the heat exchanging unit 4 by solar heat. Although the case where it was applied to a hot water supply system was shown, the solar heat collection part, the pump and the hot water storage tank are interposed in the water circulation circuit, and the water in the hot water tank is circulated in the water circulation circuit and heated by solar heat. It can also be applied to solar hot water supply systems using solar heat, and can also be applied to non-circular solar hot water supply systems using solar heat. It is also possible to apply to.

また、上記の実施形態では、太陽熱によって加温する流体として、熱媒体として機能させた水を用いた場合を示したが、熱の受け渡しを行う熱媒体に限らないし、水にも限られないし、各種の液体や気体等が用いられてよく、それに応じて、ポンプに替わる各種の駆動源が用いられてよい。   Further, in the above embodiment, the case where water functioned as a heat medium is used as a fluid heated by solar heat, but is not limited to a heat medium that transfers heat, and is not limited to water, Various liquids, gases, and the like may be used, and various drive sources instead of the pumps may be used accordingly.
