Description

本発明は、自然エネルギーを利用した２４時間換気システムに関する。   The present invention relates to a 24-hour ventilation system using natural energy.

住宅等の建物において、屋内を毎日２４時間換気することが行われる、あるいは求められるようになってきているが、２４時間換気システムにおいて、換気用のファンの駆動は、商用電源からの電気を用いることで行われている。   In a building such as a house, indoor ventilation is being or is required every day for 24 hours. In a 24-hour ventilation system, a fan for ventilation uses electricity from a commercial power source. It is done by that.

しかしながら、この換気システムでは、換気用ファンを毎日２４時間絶え間なく駆動し続けなければならないため、ひと月の電気代が高くついてしまうという問題がある。   However, with this ventilation system, the ventilation fan must be continuously driven for 24 hours every day, so that there is a problem that the electricity bill for one month is high.

本発明は、上記のような問題点に鑑み、換気用ファンを毎日２４時間安定して駆動し続けることができ、しかも、電気代を低く抑えることができる２４時間換気システムを提供することを課題とする。   SUMMARY OF THE INVENTION In view of the above problems, the present invention is to provide a 24-hour ventilation system that can continuously drive a ventilation fan for 24 hours every day and that can keep the electricity bill low. And

上記の課題は、自然エネルギーで発電を行う発電機と、該発電機で発電した電気を蓄電するバッテリーとが備えられ、該バッテリーの電気で２４時間換気用のファンが駆動するようになされていることを特徴とする自然エネルギーを利用した２４時間換気システムによって解決される。なお、自然エネルギーは、例えば、風力、太陽光などからなる。   The above-described problem includes a generator that generates power using natural energy, and a battery that stores electricity generated by the generator, and the fan for ventilation for 24 hours is driven by the electricity of the battery. This is solved by a 24-hour ventilation system using natural energy. In addition, natural energy consists of a wind force, sunlight, etc., for example.

このシステムでは、自然エネルギーを利用して発電が行われ、その電気で換気用のファンが駆動するようになされているので、商用電力の消費が抑えられて、電気代を低くすることができる。   In this system, power is generated using natural energy, and the ventilation fan is driven by the electricity. Therefore, the consumption of commercial power can be suppressed and the electricity bill can be reduced.

しかも、発電した電気を蓄電するバッテリーが備えられ、該バッテリーに蓄えられた電気で換気用のファンを駆動するようになされているので、自然エネルギーによる発電が行われている時間帯であるか否かを問わず、換気用ファンをバッテリーに蓄電された電気で駆動し続けることができて、換気用ファンを毎日２４時間安定して駆動し続けることができる。   Moreover, since a battery for storing the generated electricity is provided and the fan for ventilation is driven by the electricity stored in the battery, whether or not it is a time zone in which electricity is generated by natural energy Regardless of this, the ventilation fan can be continuously driven by the electricity stored in the battery, and the ventilation fan can be stably driven for 24 hours every day.

特に、自然エネルギーから得られる電気によって駆動しようとする対象が、２４時間換気システムにおける換気用ファンであるので、バッテリーの併用のもとで、発電機として、発電量の小さい小型発電機を用いて２４時間換気を実現でき、自然エネルギーを利用した小型発電機の普及を促進することができる。   In particular, since the target to be driven by electricity obtained from natural energy is a ventilation fan in a 24-hour ventilation system, a small generator with a small amount of power generation is used as a generator under the combined use of a battery. 24 hours ventilation can be realized, and the spread of small generators using natural energy can be promoted.

上記の換気システムにおいて、バッテリーの蓄電量が所定の蓄電量を下回ったとき、換気用ファンが商用電源からとりだされた電気で駆動するようになされているのもよい。この場合は、自然エネルギーによる発電が不足し、バッテリーの蓄電量が少なくなったときであっても、商用電力からの電気で換気用ファンが駆動され、換気用ファンのより安定した駆動を実現することができる。しかも、自然エネルギーから得られる電気と商用電源からの電気を併用する構成であるので、商用電力の消費量を抑えて電気代を低くすることができる。   In the ventilation system, the ventilation fan may be driven by electricity extracted from a commercial power source when the amount of electricity stored in the battery falls below a predetermined amount of electricity stored. In this case, even when the amount of electricity generated by natural energy is insufficient and the amount of electricity stored in the battery is low, the ventilation fan is driven by electricity from commercial power, realizing a more stable drive of the ventilation fan. be able to. And since it is the structure which uses together the electricity obtained from natural energy and the electricity from a commercial power supply, the consumption of commercial power can be suppressed and an electricity bill can be made low.

この換気システムにおいて、商用電源からの電気はバッテリーに蓄電され、その電気で換気用ファンが駆動するようになされており、かつ、商用電源によるバッテリーの充電は深夜電力の時間帯において行われるようになされているのもよい。この場合は、換気用ファンの駆動に商用電力を用いるものでありながら、バッテリーと安価な深夜電力の併用によって電気代を効果的に低く抑えることができる。   In this ventilation system, electricity from the commercial power source is stored in the battery, the ventilation fan is driven by the electricity, and charging of the battery by the commercial power source is performed in the time zone of midnight power. It is good to have been made. In this case, although the commercial power is used to drive the ventilation fan, the electricity cost can be effectively reduced by the combined use of the battery and inexpensive midnight power.

この換気システムにおいて、バッテリーの蓄電容量が、換気用ファンを概ね一日駆動するのに要する電力量よりも大きく、かつ、
商用電源によるバッテリーへの充電量は、バッテリーの蓄電量が換気用ファンを概ね一日駆動するのに要する量となる量であるとよい。 In this ventilation system, the storage capacity of the battery is greater than the amount of power required to drive the ventilation fan for approximately one day, and
The amount of charge to the battery by the commercial power source may be an amount that the amount of electricity stored in the battery is an amount required to drive the ventilation fan for approximately one day.

このシステムでは、商用電源によるバッテリーへの充電量は、バッテリーの蓄電量が換気ファンを概ね一日駆動するのに要する量となる量であるので、この充電が行われた後、仮に、まる一日程度、自然エネルギーによる発電が行われなかったとしても、換気用ファンが停止してしまうことはなく、しかも、商用電源による充電は充電開始時の蓄電残量に応じて必要最小限度であるので、深夜電力といえども、その電力消費を少なく抑えて電気代を低くすることができる。加えて、まる一日程度経過すると再度深夜電力の時間帯が訪れるので、その時間帯にバッテリーの充電をコスト的に有利に行うことができる。更に、バッテリーの蓄電容量は、換気ファンを概ね一日駆動するのに要する電力量よりも大きいので、深夜電力による充電後に自然エネルギーによる発電が行われた場合であっても、その電気がバッテリーに蓄電され、自然エネルギーの効率の良い利用を実現することができる。   In this system, the amount of charge to the battery by the commercial power source is an amount that the amount of electricity stored in the battery is the amount required to drive the ventilation fan for approximately one day. Even if power generation by natural energy is not performed for about a day, the ventilation fan will not stop, and charging by the commercial power supply is the minimum necessary depending on the remaining power storage at the start of charging Even in the case of midnight power, the electricity cost can be reduced by reducing the power consumption. In addition, after about a whole day, the midnight power time period comes again, so that the battery can be charged advantageously in that time period. In addition, the battery's storage capacity is greater than the amount of power required to drive the ventilation fan for approximately one day, so even if the power is generated by natural energy after charging with midnight power, the electricity is transferred to the battery. Electric power is stored and efficient use of natural energy can be realized.

本発明は、以上のとおりのものであるから、換気用ファンを毎日２４時間安定して駆動し続けることができ、しかも、電気代を低く抑えることができる。   Since the present invention is as described above, the ventilation fan can be driven stably for 24 hours every day, and the electricity bill can be kept low.

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に示す実施形態の２４時間換気システムにおいて、１は換気用ファン、２は自然エネルギーで発電を行う発電機、３はバッテリー、４はインバーター等を含むパワーコンディショナーである。   In the 24-hour ventilation system of the embodiment shown in FIG. 1, 1 is a ventilation fan, 2 is a generator that generates power using natural energy, 3 is a battery, 4 is a power conditioner including an inverter and the like.

自然エネルギー発電機２は、風車５と風車用発電部６と太陽電池７とを備え、風力と太陽光で発電を行うハイブリッド形の発電機からなり、該発電機２の発電によって得られる電気がバッテリー３に蓄えられ、バッテリー３に蓄えられた電気で換気用ファン１が駆動するようになされている。   The natural energy generator 2 includes a wind turbine 5, a wind turbine generator 6, and a solar battery 7, and includes a hybrid generator that generates power using wind and sunlight. The ventilation fan 1 is driven by the electricity stored in the battery 3 and the electricity stored in the battery 3.

また、自然エネルギーによる発電が不足した場合のアシストのため、バッテリー３は商用電源８からの電気によっても充電されるようになされており、バッテリー３の蓄電量が所定の蓄電量を下回ったときに、バッテリー３の充電が商用電源８によって行われ、その電気で換気用ファン１が駆動を続けられるようになされている。   In addition, the battery 3 is also charged by electricity from the commercial power source 8 for assisting in the case where power generation by natural energy is insufficient, and when the charged amount of the battery 3 falls below a predetermined charged amount. The battery 3 is charged by the commercial power source 8, and the ventilation fan 1 can be continuously driven by the electricity.

そして、本実施形態では、商用電源８は、例えば午後１１時から午前７時までの電力を割安で利用できる深夜電力利用契約のなされたものからなっていて、商用電源８によるバッテリー３の充電は、制御によって、この深夜電力の時間帯（図２及び図３に示す斜線ハッチング領域１０の時間帯）において行われるようになされている。   In the present embodiment, the commercial power source 8 is, for example, a contract for a late-night power usage that allows the power from 11:00 pm to 7:00 am to be used at a reasonable price. The control is performed in the time zone of this midnight power (the time zone of the hatched area 10 shown in FIGS. 2 and 3).

深夜電力によるバッテリー３への充電量は、バッテリー３の蓄電量が換気用ファン１を概ね一日駆動するのに要する量となる量に制御されるようになされており、仮に、自然エネルギー発電機２が何日かにわたって発電を行わない場合であっても、商用の深夜電力のみで換気用ファン１が駆動を続けられ、しかも、深夜電力といえども必要以上には商用電力を使用しないようになされている。   The amount of charge to the battery 3 by midnight power is controlled so that the amount of electricity stored in the battery 3 is approximately the amount required to drive the ventilation fan 1 for one day. Even if the power generator 2 does not generate power for several days, the ventilation fan 1 can continue to be driven only by commercial late-night power, and even if it is late-night power, do not use commercial power more than necessary. Has been made.

また、バッテリー３の充電容量は、換気用ファン１を概ね一日駆動するのに要する電力量よりも大きく設定されていて、商用電力でバッテリー３が充電された直後であっても、自然エネルギーによる発電が行われれば、その電気でバッテリー３が充電されるようになされている。   Further, the charging capacity of the battery 3 is set to be larger than the amount of electric power required to drive the ventilation fan 1 for approximately one day, and even after the battery 3 is charged with commercial power, it depends on natural energy. When power generation is performed, the battery 3 is charged with the electricity.

上記の２４時間換気システムでは、バッテリー３は、換気用ファン１の駆動によって常時放電を行っていく一方で、自然エネルギー発電機２で発電が行われればその充電を行い、また、必要に応じて商用電源８から深夜電力で充電を行う。具体的には、図２に白抜き矢印９で示すように、自然エネルギー発電機２での発電が日々活発に行われる場合には、その電気だけで換気用ファン１は駆動を続け、２４時間換気がコスト的に有利に実現される。   In the 24-hour ventilation system described above, the battery 3 is always discharged by driving the ventilation fan 1, while it is charged if the natural energy generator 2 generates power, and if necessary, the battery 3 is charged. Charging is performed from commercial power supply 8 with late-night power. Specifically, as shown by the white arrow 9 in FIG. 2, when the natural energy generator 2 is actively generating power every day, the ventilation fan 1 continues to be driven only by that electricity for 24 hours. Ventilation is realized cost-effectively.

また、図３に示すように、自然エネルギー発電機２による発電が天候等との関係であまり活発ではなく、バッテリー３の蓄電量が、深夜電力の時間帯１０における特定の設定時刻１１において、換気用ファン１を概ね一日駆動するのに要する量を下回っている場合には、バッテリー３は、実線矢印範囲１２で示すように、商用電源８による充電によって、蓄電量が換気用ファン１を概ね一日駆動するのに要する量となるまで充電される。   Further, as shown in FIG. 3, the power generation by the natural energy generator 2 is not very active in relation to the weather and the like, and the amount of power stored in the battery 3 is changed to ventilation at a specific set time 11 in the time zone 10 of midnight power. When the battery 3 is less than the amount required to drive the general fan 1 for a day, the battery 3 is charged by the commercial power source 8 as shown by the solid arrow range 12, so that the amount of charge is approximately equal to that of the ventilation fan 1. The battery is charged until it reaches the amount required to drive for a day.

従って、図３の第４日目の前後の状態から明らかなように、自然エネルギーによる電気の蓄電量が少なく、しかも、自然エネルギーによる発電がなされない場合であっても、商用の深夜電力による充電のみで、換気用ファン１は毎日２４時間換気を続けることができる。   Therefore, as is clear from the state before and after the fourth day in FIG. 3, even if the amount of electricity stored by natural energy is small and power generation by natural energy is not performed, charging by commercial late-night power is possible. As a result, the ventilation fan 1 can continue ventilation for 24 hours every day.

また、図３の第６日目から第７日目にかけての状態から明らかなように、深夜電力による充電完了直後から自然エネルギーによる発電が始まったような場合でも、その電気は、バッテリー３を更に充電していくのに使われ、自然エネルギーと商用電源の併用という構成のなかで自然エネルギーによって得られる電気を有効利用していくことができる。   In addition, as is apparent from the state from the sixth day to the seventh day in FIG. 3, even when the generation of natural energy starts immediately after the completion of charging by midnight power, the electricity further It is used for charging and can effectively use electricity obtained from natural energy in a combination of natural energy and commercial power.

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、商用電源８として、深夜電力利用契約のなされた商用電源を使用し、そこから得られる電気を深夜電力の時間帯においてバッテリー３に充電する場合について示しているが、商用電源は深夜電力の契約をしていない通常の商用電源であってもよいし、商用電源８によるバッテリーの充電開始時刻はいつに設定されていてもよいし、商用電源８によるバッテリー３への充電量は、バッテリー３の蓄電量が換気用ファン１を概ね一日駆動するのに要する量となる量でなくてもよく、例えば二日あるいは三日等に複数日にわたって駆動するのに要する量となる量であってもよいことはいうまでもない。   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, the commercial power source 8 is a commercial power source with a midnight power usage contract, and the battery 3 is charged with electricity obtained from the commercial power source in the midnight power time zone. The commercial power source may be a normal commercial power source that does not have a midnight power contract, the battery charging start time of the commercial power source 8 may be set at any time, and the commercial power source 8 may be connected to the battery 3. The amount of charge does not have to be the amount that the amount of electricity stored in the battery 3 is required to drive the ventilation fan 1 for approximately one day. For example, the amount that is required to drive the ventilation fan 1 over a plurality of days such as two or three days. Needless to say, the amount may be as follows.

また、上記の実施形態では、商用電源をバッテリー３の充電に用いた場合を示しているが、バッテリー３の蓄電量が不足したとき、換気用ファンが商用電源からの電気で直接駆動されるようにしてもよい。もちろん、自然エネルギーによる発電電気のみでバッテリーを充電し、その電気だけで換気用ファンを駆動する構成としてもよい。   Moreover, although the case where the commercial power source is used for charging the battery 3 is shown in the above embodiment, the ventilation fan is directly driven by electricity from the commercial power source when the storage amount of the battery 3 is insufficient. It may be. Of course, the battery may be charged only with the electricity generated by natural energy, and the ventilation fan may be driven only with the electricity.
