Description

本発明は、ガス式給湯熱源機および電気式給湯熱源機を備えた給湯装置、および、給湯システムに関する。   The present invention relates to a hot water supply apparatus including a gas hot water supply heat source device and an electric hot water supply heat source device, and a hot water supply system.

近年、ガスを消費して給水を加熱するガス式給湯熱源機に加えて、電力を消費して給水を加熱する電気式給湯熱源機を備えたハイブリッド式の給湯装置が普及し始めている。   2. Description of the Related Art In recent years, hybrid hot water supply apparatuses including an electric hot water supply source that consumes electric power and heats water supply in addition to a gas hot water supply source that consumes gas and heats water supply have begun to spread.

このような給湯装置において、電気式給湯熱源機によって加熱された給水をガス式給湯熱源機でさらに加熱可能な構成とし、電気式給湯熱源機によって加熱された給水の温度が設定温度を超えた場合に、ガス式給湯熱源機の運転を停止する技術が開発されている（例えば、特許文献１）。   In such a hot water supply device, when the water heated by the electric hot water source is configured to be further heated by the gas hot water source, the temperature of the hot water heated by the electric hot water source exceeds the set temperature.

上記給湯装置で利用されるエネルギーとしてのガスや電力は、時間帯、外気温度、季節等によって需要が異なる。例えば、電力は、昼間の時間帯において相対的に需要が多くなり、深夜の時間帯において相対的に需要が少なくなる。したがって、ガス供給会社や電力供給会社といったエネルギー供給事業者は、需要が最も多くなる時間帯（ピーク時）に対応できる設備を保有する必要がある。   The demand for gas and electric power as energy used in the hot water supply device varies depending on the time of day, outside air temperature, season, and the like. For example, the demand for electric power is relatively high during daytime hours, and the demand is relatively low during late-night time periods. Therefore, an energy supply company such as a gas supply company or an electric power supply company needs to have equipment that can cope with a time zone (peak time) when demand is greatest.

そうすると、ピーク時より需要が少ない時間帯においては、設備の一部を停止させることになり、設備全体の稼働率が低下するという問題がある。   If it does so, in the time slot | zone when there is less demand than a peak time, a part of installation will be stopped and there exists a problem that the operation rate of the whole installation falls.

本発明は、このような課題に鑑み、エネルギー供給事業者の設備全体の稼働率の向上を促すことが可能な給湯装置、および、給湯システムを提供することを目的としている。   In view of such a problem, an object of the present invention is to provide a hot water supply device and a hot water supply system that can promote an improvement in the operating rate of the entire facility of an energy supplier.

図１は、第１の実施形態にかかる給湯装置１００を説明する図である。なお、図１中、ガス、電力の流れを白抜き矢印で示し、水（給水、湯水等）の流れを実線の矢印で示し、信号の流れを破線で示す。 (1st Embodiment: Hot-water supply apparatus 100)
FIG. 1 is a diagram illustrating a hot water supply apparatus 100 according to the first embodiment. In FIG. 1, the flow of gas and electric power is indicated by white arrows, the flow of water (water supply, hot water, etc.) is indicated by solid arrows, and the flow of signals is indicated by broken lines.

図１に示すように、給湯装置１００は、ガス式給湯熱源機１１０と、電気式給湯熱源機１２０と、貯湯タンク１３０と、中央制御部１５０とを含んで構成される。   As shown in FIG. 1, the hot water supply device 100 includes a gas hot water supply heat source 110, an electric hot water supply heat source 120, a hot water storage tank 130, and a central control unit 150.

ガス式給湯熱源機１１０は、例えば、温水ボイラ、温水ヒータ、瞬間湯沸器、ＧＨＰ（ガスヒートポンプ）給湯器等で構成され、ガスを消費して（燃焼させて）、貯湯タンク１３０から供給された給水を加熱し、湯水を生成する。   The gas-type hot water supply heat source device 110 includes, for example, a hot water boiler, a hot water heater, an instantaneous water heater, a GHP (gas heat pump) hot water heater, and the like, consumes (combusts) gas, and is supplied from the hot water storage tank 130. The hot water is heated to produce hot water.

電気式給湯熱源機１２０は、例えば、電気温水器、ＥＨＰ（電気モータヒートポンプ）給湯器等で構成され、電力を消費して、貯湯タンク１３０から供給された給水を加熱し、湯水を生成する。   The electric hot water supply heat source device 120 includes, for example, an electric water heater, an EHP (electric motor heat pump) water heater, and the like, consumes electric power, heats the water supplied from the hot water storage tank 130, and generates hot water.

貯湯タンク１３０には、給水が供給されるとともに、ガス式給湯熱源機１１０および電気式給湯熱源機１２０によって生成された湯水が供給される。したがって、貯湯タンク１３０は、給水と、ガス式給湯熱源機１１０および電気式給湯熱源機１２０によって生成された湯水とを貯湯（貯留）することとなる。こうして、貯湯タンク１３０に貯湯された湯水（給湯）は、供給先の要求に基づいて供給されることとなる。   Hot water is supplied to the hot water storage tank 130 and hot water generated by the gas hot water supply heat source 110 and the electric hot water supply heat source 120 is supplied. Therefore, the hot water storage tank 130 stores (stores) hot water and hot water generated by the gas hot water supply heat source 110 and the electric hot water supply heat source 120. Thus, the hot water (hot water supply) stored in the hot water storage tank 130 is supplied based on the request of the supply destination.

中央制御部１５０は、ＣＰＵ（中央処理装置）を含む半導体集積回路で構成され、ＲＯＭからＣＰＵ自体を動作させるためのプログラムやパラメータ等を読み出し、ワークエリアとしてのＲＡＭや他の電子回路と協働して給湯装置１００全体を管理および制御する。本実施形態において、中央制御部１５０は、装置通信部１５２、運転制御部１５４として機能する。   The central control unit 150 is composed of a semiconductor integrated circuit including a CPU (central processing unit), reads a program, parameters, and the like for operating the CPU itself from a ROM, and cooperates with a RAM as a work area and other electronic circuits. Thus, the entire hot water supply apparatus 100 is managed and controlled. In the present embodiment, the central control unit 150 functions as the device communication unit 152 and the operation control unit 154.

装置通信部１５２は、ガス供給会社の管理サーバと通信を確立し、ガス供給会社から、所定期間（例えば、１日）におけるガス目標供給量の推移を示すガス目標情報を取得する。ガス目標供給量の推移は、ガス供給会社が保有するガス供給設備の能力、季節、外気温度、給湯装置１００が設置される施設が属する地域（町、区、市、都、道、府、県等）等に基づいて設定される。また、装置通信部１５２は、１日毎に、該当するガス目標情報を取得してもよいし、数日おき、週毎、季節毎にガス目標情報を取得してもよい。   The apparatus communication unit 152 establishes communication with the management server of the gas supply company, and acquires gas target information indicating the transition of the gas target supply amount during a predetermined period (for example, one day) from the gas supply company. Trends in gas target supply volume are the capacity of gas supply facilities owned by the gas supply company, the season, the outside air temperature, and the area to which the facility where the water heater 100 is installed (town, ward, city, capital, road, prefecture, prefecture) Etc.) etc. Moreover, the apparatus communication part 152 may acquire applicable gas target information every day, and may acquire gas target information every several days, every week, and every season.

運転制御部１５４は、要求熱量を満たすように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０それぞれの運転負荷を決定し、決定した運転負荷でガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転を制御する。   The operation control unit 154 determines the operation loads of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 so as to satisfy the required heat amount, and the gas hot water supply heat source device 110 and the electric hot water supply heat source with the determined operation loads. The operation of the machine 120 is controlled.

具体的に説明すると、運転制御部１５４は、まず、要求熱量を満たすガス式給湯熱源機１１０および電気式給湯熱源機１２０それぞれの運転負荷（または運転比率）を仮決定する。ここで、要求熱量は、供給先から要求される湯水の量（要求湯水量）と、湯水の要求温度とを満たすために、貯湯タンク１３０に投入される熱量（ガス式給湯熱源機１１０が生成する湯水の熱量および電気式給湯熱源機１２０が生成する湯水の熱量の合計）である。例えば、要求熱量は、要求湯水量、要求湯温、貯湯タンク１３０の残量に基づいて決定される。   Specifically, the operation control unit 154 first temporarily determines the operation loads (or operation ratios) of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 that satisfy the required heat amount. Here, the required amount of heat is the amount of heat input to the hot water storage tank 130 in order to satisfy the amount of hot water required by the supplier (requested amount of hot water) and the required temperature of hot water (generated by the gas hot water supply heat source 110). And the total amount of hot water generated by the electric hot water supply heat source 120). For example, the required heat amount is determined based on the required hot water amount, the required hot water temperature, and the remaining amount of the hot water storage tank 130.

続いて、運転制御部１５４は、仮決定したガス式給湯熱源機１１０の運転負荷に基づいてガスデマンドを算出する。ガスデマンドは、仮決定した運転負荷でガス式給湯熱源機１１０を運転させるために必要なガス消費量である。また、運転制御部１５４は、仮決定した電気式給湯熱源機１２０の運転負荷に基づいて電力デマンドを算出する。電力デマンドは、仮決定した運転負荷で電気式給湯熱源機１２０を運転させるために必要な電力消費量である。   Subsequently, the operation control unit 154 calculates a gas demand based on the temporarily determined operation load of the gas hot water supply heat source apparatus 110. The gas demand is a gas consumption amount necessary for operating the gas hot water supply heat source device 110 with a temporarily determined operation load. In addition, the operation control unit 154 calculates a power demand based on the temporarily determined operation load of the electric hot water supply heat source machine 120. The electric power demand is the electric power consumption necessary for operating the electric hot water supply heat source machine 120 with the temporarily determined operation load.

そして、運転制御部１５４は、算出したガスデマンドと、上記ガス目標供給量とを所定時間間隔（例えば、ｎ分ごと、ｎ時間ごと等）で比較し、ガス式給湯熱源機１１０および電気式給湯熱源機１２０それぞれの運転負荷を決定し、決定した運転負荷でガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転を制御する。   Then, the operation control unit 154 compares the calculated gas demand with the gas target supply amount at predetermined time intervals (for example, every n minutes, every n hours, etc.), and the gas hot water supply heat source 110 and the electric hot water supply are compared. The operation load of each heat source device 120 is determined, and the operation of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 is controlled with the determined operation load.

図２は、第１の実施形態にかかる運転制御部１５４による運転負荷の決定処理を説明する図である。なお、図２中、ガスデマンドを実線で示し、ガス目標供給量を破線で示す。   FIG. 2 is a diagram for explaining operation load determination processing by the operation control unit 154 according to the first embodiment. In FIG. 2, the gas demand is indicated by a solid line, and the gas target supply amount is indicated by a broken line.

図２に示すように、ガスデマンドが、ガス目標供給量を基準とする所定のガス目標範囲の上限値を上回る場合（図２では、１時〜４時、８時〜１２時、１８時〜２４時）、運転制御部１５４は、ガスデマンドとガス目標供給量との差分を算出し、算出した差分でガス式給湯熱源機１１０が生成できる湯水の熱量（差分熱量Ｓ）を導出する。続いて、運転制御部１５４は、電力デマンドと、電気式給湯熱源機１２０の最大出力（現在の最大出力）とに基づいて、電気式給湯熱源機１２０が追加で生成できる湯水の熱量（以下、「電力余力熱量Ｄ」と称する）を算出する。そして、運転制御部１５４は、電力余力熱量Ｄと、差分熱量Ｓとを比較する。   As shown in FIG. 2, when the gas demand exceeds the upper limit value of a predetermined gas target range based on the gas target supply amount (in FIG. 2, 1 to 4 o'clock, 8 o'clock to 12 o'clock, 18 o'clock to 24 o'clock), the operation control unit 154 calculates the difference between the gas demand and the target gas supply amount, and derives the amount of hot water (difference heat amount S) that can be generated by the gas-type hot water supply heat source device 110 using the calculated difference. Subsequently, the operation control unit 154 determines the amount of hot water heat that can be additionally generated by the electric hot water supply heat source device 120 based on the power demand and the maximum output (current maximum output) of the electric hot water supply heat source device 120 (hereinafter, (Referred to as “power surplus heat D”). Then, the operation control unit 154 compares the power surplus heat quantity D with the differential heat quantity S.

電力余力熱量Ｄ＝差分熱量Ｓである場合、運転制御部１５４は、電気式給湯熱源機１２０の運転負荷を最大出力まで増加させるとともに、ガス式給湯熱源機１１０の運転負荷をガス目標供給量となる運転負荷まで低下させる。また、電力余力熱量Ｄ>差分熱量Ｓである場合、運転制御部１５４は、電気式給湯熱源機１２０の運転負荷を差分熱量Ｓに相当する運転負荷まで増加させるとともに、ガス式給湯熱源機１１０の運転負荷をガス目標供給量となる運転負荷まで低下させる。   When the power surplus heat amount D = the difference heat amount S, the operation control unit 154 increases the operation load of the electric hot water supply heat source device 120 to the maximum output, and the operation load of the gas hot water supply heat source device 110 as the gas target supply amount. To lower the operating load. In addition, when the power surplus heat amount D> the differential heat amount S, the operation control unit 154 increases the operation load of the electric hot water supply heat source device 120 to the operation load corresponding to the differential heat amount S and the gas hot water supply heat source device 110. The operating load is reduced to the operating load that is the target gas supply amount.

一方、電力余力熱量Ｄ<差分熱量Ｓである場合、運転制御部１５４は、電気式給湯熱源機１２０の運転負荷を最大出力まで増加させるとともに、ガス式給湯熱源機１１０の運転負荷を低下させる。電気式給湯熱源機１２０は、ガス式給湯熱源機１１０と比較して、応答性が低いため、瞬時に熱量を増加させることは困難である。したがって、電力余力熱量Ｄ<差分熱量Ｓである場合には、ガス式給湯熱源機１１０の運転負荷を低下させることで、実際のガスの消費量をガス目標供給量に近づける。   On the other hand, when the electric power surplus heat quantity D <the differential heat quantity S, the operation control unit 154 increases the operation load of the electric hot water supply heat source device 120 to the maximum output and reduces the operation load of the gas hot water supply heat source device 110. The electric hot water supply heat source device 120 is less responsive than the gas hot water supply heat source device 110, so it is difficult to increase the amount of heat instantaneously. Therefore, when the power surplus heat amount D <the difference heat amount S, the actual gas consumption amount is brought close to the gas target supply amount by reducing the operation load of the gas hot water supply heat source device 110.

また、電力余力熱量Ｄが０である場合、運転制御部１５４は、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷調整を行わない。これにより、給湯装置１００が供給する熱量が要求熱量未満となる事態を回避することができる。   Moreover, when the electric power surplus heat quantity D is 0, the operation control unit 154 does not adjust the operation load of the gas hot water supply heat source 110 and the electric hot water supply heat source 120. Thereby, the situation where the amount of heat supplied by hot water supply apparatus 100 is less than the required amount of heat can be avoided.

また、ガスデマンドがガス目標範囲の下限値未満である場合（図２では、４時〜８時）、運転制御部１５４は、ガス式給湯熱源機１１０の運転負荷をガス目標供給量となる運転負荷まで増加させるとともに、電気式給湯熱源機１２０の運転負荷を低下させる（または、電気式給湯熱源機１２０を停止させる）。   When the gas demand is less than the lower limit value of the gas target range (4 to 8 in FIG. 2), the operation control unit 154 performs an operation in which the operation load of the gas hot water supply heat source device 110 becomes the gas target supply amount. While increasing the load, the operation load of the electric hot water supply heat source 120 is reduced (or the electric hot water supply heat source 120 is stopped).

また、ガスデマンドがガス目標範囲内である場合（図２中、１２時〜１８時）、運転制御部１５４は、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷の調整は行わない。   When the gas demand is within the gas target range (12:00 to 18:00 in FIG. 2), the operation control unit 154 adjusts the operation load of the gas hot water supply heat source 110 and the electric hot water supply heat source 120. Absent.

以上説明したように、本実施形態にかかる給湯装置１００によれば、運転制御部１５４が、ガス供給会社が設定したガス目標供給量を過不足なく消費する運転負荷でガス式給湯熱源機１１０を運転させることができる。したがって、ガス供給会社が保有するガス供給設備の稼働率が所定値以上となるようにガス目標供給量を設定すれば、ガス供給設備全体の稼働率を向上させることができる。   As described above, according to the hot water supply apparatus 100 according to the present embodiment, the operation control unit 154 operates the gas hot water supply heat source 110 with an operation load that consumes the target gas supply amount set by the gas supply company without excess or deficiency. Can be driven. Therefore, if the target gas supply amount is set so that the operation rate of the gas supply facility owned by the gas supply company is equal to or higher than a predetermined value, the operation rate of the entire gas supply facility can be improved.

これにより、給湯装置１００を備えない地域のガス供給設備と比較して、ガス供給設備自体を縮小することが可能となる。例えば、ガスホルダを縮小できたり、ガスの導管を細くしたりすることができる。したがって、ガス供給設備の建設費用を削減でき、ガスの単価を安くすることが可能となる。そして、結果的に、給湯装置１００を備える需要家のガス料金を低下させることができる。   This makes it possible to reduce the gas supply facility itself as compared to a gas supply facility in an area that does not include the hot water supply device 100. For example, the gas holder can be reduced, or the gas conduit can be narrowed. Therefore, the construction cost of the gas supply facility can be reduced, and the unit price of gas can be reduced. As a result, the gas charge of a consumer who includes the hot water supply device 100 can be reduced.

また、本実施形態にかかる給湯装置１００の適用が増加するほど、ガス目標供給量の変動は小さくなり、最終的には、変動がなくなる（ガス目標供給量が全期間を通じて１の値に収束する）と考えられる。   In addition, as the application of the hot water supply apparatus 100 according to the present embodiment increases, the fluctuation of the gas target supply amount becomes smaller and eventually does not change (the gas target supply amount converges to a value of 1 throughout the entire period). )it is conceivable that.

（第２の実施形態）
上記第１の実施形態では、運転制御部１５４が、ガス目標供給量に基づいてガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定する構成を例に挙げた。しかし、運転制御部１５４は、ガス目標供給量に加えて、電力供給会社が提供する電力目標供給量に基づいて、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定してもよい。第２の実施形態では、ガス目標供給量および電力目標供給量に基づいて、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定する構成について説明する。 (Second Embodiment)
In the said 1st Embodiment, the operation control part 154 gave the example of the structure which determines the operation load of the gas type hot water supply heat source machine 110 and the electric hot water supply heat source machine 120 based on the gas target supply amount. However, the operation control unit 154 determines the operation loads of the gas hot water supply heat source 110 and the electric hot water supply heat source 120 based on the target power supply provided by the power supply company in addition to the target gas supply. Also good. 2nd Embodiment demonstrates the structure which determines the operation load of the gas type hot water supply heat source machine 110 and the electric hot water supply heat source machine 120 based on a gas target supply amount and an electric power target supply amount.

第２の実施形態において、装置通信部１５２は、ガス供給会社の管理サーバと通信を確立し、ガス供給会社から、所定期間（例えば、１日）におけるガス目標供給量の推移を示すガス目標情報を取得するとともに、電力供給会社の管理サーバと通信を確立し、電力供給会社から、所定期間（例えば、１日）における電力目標供給量の推移を示す電力目標情報を取得する。電力供給量の推移は、電力供給会社が保有する電力供給設備の能力、季節、外気温度、給湯装置１００が設置される施設が属する地域（町、区、市、都、道、府、県等）等に基づいて設定される。また、装置通信部１５２は、１日毎に、該当する電力目標情報を取得してもよいし、数日おき、週毎、季節毎に電力目標情報を取得してもよい。   In the second embodiment, the apparatus communication unit 152 establishes communication with the management server of the gas supply company, and gas target information indicating the transition of the gas target supply amount in a predetermined period (for example, one day) from the gas supply company. And establishing communication with the management server of the power supply company, and acquiring power target information indicating the transition of the power target supply amount during a predetermined period (for example, one day) from the power supply company. The change in the amount of power supply depends on the capacity of the power supply equipment owned by the power supply company, the season, the outside air temperature, the area to which the hot water supply device 100 is located (town, ward, city, capital, road, prefecture, prefecture, etc. ) And the like. Moreover, the apparatus communication part 152 may acquire applicable electric power target information for every day, and may acquire electric power target information for every several days, every week, and every season.

運転制御部１５４は、ガスデマンドと、上記ガス目標供給量とを所定時間間隔（例えば、ｎ分ごと、ｎ時間ごと等）で比較するとともに、電力デマンドと、上記電力目標供給量とを所定時間間隔（例えば、ｎ分ごと、ｎ時間ごと等）で比較し、ガス式給湯熱源機１１０および電気式給湯熱源機１２０それぞれの運転負荷を決定し、決定した運転負荷でガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転を制御する。以下に、具体的な制御処理について説明する。   The operation control unit 154 compares the gas demand with the gas target supply amount at a predetermined time interval (for example, every n minutes, every n hours, etc.), and compares the power demand with the power target supply amount for a predetermined time. Comparison is made at intervals (for example, every n minutes, every n hours, etc.), the operating loads of the gas hot water supply heat source 110 and the electric hot water supply heat source 120 are determined, and the gas hot water supply heat source 110 and the The operation of the electric hot water supply heat source machine 120 is controlled. Specific control processing will be described below.

図３〜図７は、第２の実施形態にかかる運転制御部１５４による運転負荷の決定処理を説明する図である。なお、図３〜図７中、ガスデマンドを実線で示し、ガス目標供給量を破線で示し、電力デマンドを一点鎖線で示し、電力目標供給量を二点鎖線で示す。   3-7 is a figure explaining the determination process of the driving load by the driving | operation control part 154 concerning 2nd Embodiment. 3 to 7, the gas demand is indicated by a solid line, the gas target supply amount is indicated by a broken line, the power demand is indicated by a one-dot chain line, and the power target supply amount is indicated by a two-dot chain line.

なお、ガスはガスホルダや導管内に一時的に溜めておくことができるため、負荷変動（要求熱量の変動）があっても、ガス供給設備の稼働率に対する影響は少ない。一方、電力は電線等に溜めておくことが不可能であるため、負荷変動に応じて、電力供給設備の稼働率を調整する必要がある。したがって、例えば、ガスデマンドとガス目標供給量との差分（以下、「ガス差分」と称する）と、電力デマンドと電力目標供給量との差分（以下、「電力差分」と称する）とが等しい場合（例えば、両方とも１ｋＷ）であっても、差分を調整しようとする供給元の設備の稼働率の変動（影響）は、電力の方がガスより数倍大きく、また、電力の方がガスより設備の稼働率の調整が難しい。   In addition, since gas can be temporarily stored in a gas holder or a conduit, even if there is a load change (change in required heat amount), there is little influence on the operating rate of the gas supply facility. On the other hand, since it is impossible to store electric power in an electric wire or the like, it is necessary to adjust the operating rate of the power supply facility according to load fluctuations. Therefore, for example, when the difference between the gas demand and the gas target supply amount (hereinafter referred to as “gas difference”) is equal to the difference between the power demand and the power target supply amount (hereinafter referred to as “power difference”). Even if (for example, both are 1 kW), the fluctuation (influence) of the operating rate of the equipment of the supplier trying to adjust the difference is several times larger than that of gas for power, and more than that of gas for power. It is difficult to adjust the operating rate of equipment.

そこで、本実施形態（図３〜図７を含む）では、電力デマンドに所定の係数を乗算した値を電力デマンドとして用い、電力目標供給量に所定の係数を乗算した値を電力目標供給量として用い、所定の係数を乗算した電力デマンドと、所定の係数を乗算した電力目標供給量との差分を補正電力差分として用いることとする。   Therefore, in the present embodiment (including FIGS. 3 to 7), a value obtained by multiplying the power demand by a predetermined coefficient is used as the power demand, and a value obtained by multiplying the power target supply amount by the predetermined coefficient is used as the power target supply amount. The difference between the power demand multiplied by the predetermined coefficient and the power target supply amount multiplied by the predetermined coefficient is used as the corrected power difference.

図３に示す時刻Ｔ１、Ｔ２、Ｔ３、Ｔ４では、ガスデマンドがガス目標供給量未満であり、電力デマンドが電力目標供給量を上回る。この際、運転制御部１５４は、ガス式給湯熱源機１１０の運転負荷を増加させるとともに、電気式給湯熱源機１２０の運転負荷を低下させる。また、図４に示す時刻Ｔ５、Ｔ６、Ｔ７、Ｔ８では、ガスデマンドがガス目標供給量を上回り、電力デマンドが電力目標供給量未満である。この際、運転制御部１５４は、ガス式給湯熱源機１１０の運転負荷を低下させるとともに、電気式給湯熱源機１２０の運転負荷を増加させる。   At times T1, T2, T3, and T4 shown in FIG. 3, the gas demand is less than the gas target supply amount, and the power demand exceeds the power target supply amount. At this time, the operation control unit 154 increases the operation load of the gas hot water supply heat source device 110 and decreases the operation load of the electric hot water supply heat source device 120. Also, at times T5, T6, T7, and T8 shown in FIG. 4, the gas demand exceeds the gas target supply amount, and the power demand is less than the power target supply amount. At this time, the operation control unit 154 decreases the operation load of the gas hot water supply heat source device 110 and increases the operation load of the electric hot water supply heat source device 120.

なお、図３に示す時刻Ｔ１〜時刻Ｔ４、図４に示す時刻Ｔ５〜時刻Ｔ８において、運転制御部１５４は、ガス差分と、補正電力差分とが所定の範囲内に収まるように（例えば、ガス差分の９５％〜１０５％の範囲内に補正電力差分が収まるように）、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定する。つまり、運転制御部１５４は、ガス目標供給量とガスデマンドとの乖離、および、電力目標供給量と電力デマンドとの乖離を按分するように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０を制御する。   Note that at time T1 to time T4 shown in FIG. 3 and from time T5 to time T8 shown in FIG. 4, the operation control unit 154 keeps the gas difference and the corrected power difference within a predetermined range (for example, gas The operating loads of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 are determined so that the corrected power difference falls within the range of 95% to 105% of the difference. That is, the operation control unit 154 distributes the difference between the gas target supply amount and the gas demand and the difference between the power target supply amount and the power demand to the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120. To control.

また、図５に示す時刻Ｔ９、Ｔ１０、Ｔ１１、Ｔ１２では、ガスデマンドがガス目標供給量を上回り、電力デマンドが電力目標供給量を上回る。ここで、時刻Ｔ９、Ｔ１０では、ガス差分が補正電力差分よりも小さい。そこで、運転制御部１５４は、時刻Ｔ９、Ｔ１０において、ガス式給湯熱源機１１０の運転負荷を増加させるとともに、電気式給湯熱源機１２０の運転負荷を低下させる。   In addition, at times T9, T10, T11, and T12 shown in FIG. 5, the gas demand exceeds the gas target supply amount, and the power demand exceeds the power target supply amount. Here, at times T9 and T10, the gas difference is smaller than the correction power difference. Therefore, the operation control unit 154 increases the operation load of the gas hot water supply heat source device 110 and decreases the operation load of the electric hot water supply heat source device 120 at times T9 and T10.

また、時刻Ｔ１１、Ｔ１２では、ガス差分が補正電力差分よりも大きい。そこで、運転制御部１５４は、時刻Ｔ１１、Ｔ１２において、ガス式給湯熱源機１１０の運転負荷を低下させ、電気式給湯熱源機１２０の運転負荷を増加させる。   Further, at times T11 and T12, the gas difference is larger than the correction power difference. Therefore, the operation control unit 154 reduces the operation load of the gas hot water supply heat source device 110 and increases the operation load of the electric hot water supply heat source device 120 at times T11 and T12.

また、図６に示す時刻Ｔ１３、Ｔ１４、Ｔ１５、Ｔ１６では、ガスデマンドがガス目標供給量未満であり、電力デマンドが電力目標供給量未満である。ここで、時刻Ｔ１３、Ｔ１４、Ｔ１５では、ガス差分が補正電力差分よりも大きい。そこで、運転制御部１５４は、時刻Ｔ１３、Ｔ１４、Ｔ１５において、ガス式給湯熱源機１１０の運転負荷を増加させるとともに、電気式給湯熱源機１２０の運転負荷を低下させる。   Also, at times T13, T14, T15, and T16 shown in FIG. 6, the gas demand is less than the gas target supply amount, and the power demand is less than the power target supply amount. Here, at times T13, T14, and T15, the gas difference is larger than the correction power difference. Therefore, the operation control unit 154 increases the operation load of the gas hot water supply heat source device 110 and decreases the operation load of the electric hot water supply heat source device 120 at times T13, T14, and T15.

また、時刻Ｔ１６では、ガス差分が補正電力差分よりも小さい。そこで、運転制御部１５４は、時刻Ｔ１６において、ガス式給湯熱源機１１０の運転負荷を低下させ、電気式給湯熱源機１２０の運転負荷を増加させる。   At time T16, the gas difference is smaller than the corrected power difference. Therefore, the operation control unit 154 reduces the operation load of the gas hot water supply heat source device 110 and increases the operation load of the electric hot water supply heat source device 120 at time T16.

なお、図５に示す時刻Ｔ９〜時刻Ｔ１２、図６に示す時刻Ｔ１３〜時刻Ｔ１６においても、運転制御部１５４は、ガス差分と補正電力差分とが実質的に等しくなるように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定する。   In addition, also from the time T9 to the time T12 shown in FIG. 5 and the time T13 to the time T16 shown in FIG. 6, the operation control part 154 is a gas-type hot water supply heat source so that a gas difference and a correction | amendment electric power difference may become substantially equal. The operating loads of the machine 110 and the electric hot water supply heat source machine 120 are determined.

運転制御部１５４が上記図３〜図６に示すように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０を制御すると、ガスデマンドおよび電力デマンドは、図７に示すようになる。具体的に説明すると、図７に示す時刻Ｔ１７において、運転制御部１５４は、ガス差分と補正電力差分とが実質的に等しくなるように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定し、決定した運転負荷でガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転を制御する。そうすると、例えば、図７に示す時刻Ｔ１８において、ガス差分と補正電力差分とが実質的に等しくなる。   When the operation control unit 154 controls the gas hot water supply heat source unit 110 and the electric hot water supply heat source unit 120 as shown in FIGS. 3 to 6, the gas demand and the power demand are as shown in FIG. 7. Specifically, at time T <b> 17 shown in FIG. 7, the operation control unit 154 sets the gas hot water supply heat source 110 and the electric hot water supply heat source 120 so that the gas difference and the corrected power difference are substantially equal. The operation load is determined, and the operation of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 is controlled with the determined operation load. Then, for example, at time T18 shown in FIG. 7, the gas difference and the correction power difference become substantially equal.

一方、図７に示す時刻Ｔ１９において、時刻Ｔ１８よりも要求熱量が増加したとする。この際、運転制御部１５４は、要求熱量を満たすように、ガス式給湯熱源機１１０の運転負荷を増加させるとともに、ガス差分と、補正電力差分とが等しくなるように、電気式給湯熱源機１２０の運転負荷を増加させる。そして、時刻Ｔ２０において、ガス差分と補正電力差分とが実質的に等しくなっていなければ、運転制御部１５４は、ガス差分と補正電力差分とが実質的に等しくなるまで制御を行う。   On the other hand, it is assumed that the required heat quantity is increased at time T19 shown in FIG. At this time, the operation control unit 154 increases the operation load of the gas hot water supply heat source device 110 so as to satisfy the required heat amount, and the electric hot water supply heat source device 120 so that the gas difference becomes equal to the correction power difference. Increase the operating load. If the gas difference and the corrected power difference are not substantially equal at time T20, the operation control unit 154 performs control until the gas difference and the corrected power difference are substantially equal.

以上説明したように、第２の実施形態では、運転制御部１５４が、ガス式給湯熱源機１１０へのガス供給量をガス供給会社が設定したガス目標供給量に近づけるとともに、電気式給湯熱源機１２０への電力供給量を電力供給会社が設定した電力目標供給量に近づけるように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定する。   As described above, in the second embodiment, the operation control unit 154 brings the gas supply amount to the gas hot water supply heat source device 110 closer to the gas target supply amount set by the gas supply company, and the electric hot water supply heat source device. The operating loads of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 are determined so that the power supply amount to 120 approaches the target power supply amount set by the power supply company.

したがって、ガス供給会社が保有するガス供給設備の稼働率が所定値以上となるようにガス目標供給量を設定すれば、ガス供給設備全体の稼働率を向上させることができる。また、電力供給会社が保有する電力供給設備の稼働率が所定値以上となるように電力目標供給量を設定すれば、電力供給設備全体の稼働率を向上させることができる。   Therefore, if the target gas supply amount is set so that the operation rate of the gas supply facility owned by the gas supply company is equal to or higher than a predetermined value, the operation rate of the entire gas supply facility can be improved. Moreover, if the power target supply amount is set so that the operation rate of the power supply facility owned by the power supply company is equal to or higher than a predetermined value, the operation rate of the entire power supply facility can be improved.

これにより、給湯装置１００を備えない地域の電力供給設備と比較して、電力供給設備自体を縮小することが可能となる。例えば、送電線を細くすることができる。したがって、電力供給設備の建設費用を削減でき、電力の単価を安くすることが可能となる。そして、結果的に、給湯装置１００を備える需要家の電気料金を低下させることができる。   As a result, the power supply facility itself can be reduced as compared with a power supply facility in an area where the hot water supply device 100 is not provided. For example, the transmission line can be made thin. Therefore, the construction cost of the power supply facility can be reduced, and the unit price of power can be reduced. As a result, it is possible to reduce the electricity bill of the customer who includes the hot water supply device 100.

また、給湯装置１００の適用地域が広がるほど、電力目標供給量の変動は小さくなり、最終的には、変動がなくなる（電力目標供給量が全期間を通じて１の値に収束する）と考えられる。   In addition, it is considered that as the application area of the hot water supply device 100 is expanded, the fluctuation of the power target supply amount becomes smaller and eventually does not change (the power target supply amount converges to a value of 1 throughout the entire period).

（第３の実施形態：給湯システム２００）
図８は、第３の実施形態にかかる給湯システム２００を説明する図である。なお、図８の給湯装置３００において、ガス、電力の流れを白抜き矢印で示し、水（給水、湯水等）の流れを実線の矢印で示し、信号の流れを破線で示す。 (Third embodiment: hot water supply system 200)
FIG. 8 is a diagram for explaining a hot water supply system 200 according to the third embodiment. In the hot water supply apparatus 300 of FIG. 8, the flow of gas and electric power is indicated by white arrows, the flow of water (water supply, hot water, etc.) is indicated by solid arrows, and the flow of signals is indicated by broken lines.

図８に示すように、給湯システム２００は、管理サーバ２１０と、１または複数の給湯装置３００とを含んで構成される。なお、上述した給湯装置１００と実質的に等しい構成要素については、同一の符号を付して重複説明を省略する。   As shown in FIG. 8, the hot water supply system 200 includes a management server 210 and one or more hot water supply apparatuses 300. In addition, about the component substantially equivalent to the hot-water supply apparatus 100 mentioned above, the same code | symbol is attached | subjected and duplication description is abbreviate | omitted.

管理サーバ２１０は、ガス供給会社に設けられ、所定の管理範囲（例えば、町、区、市、都、道、府、県等）全体のガス消費量等を管理する。管理範囲には、給湯装置３００を有する設備２０２と、給湯装置３００を有しないもののガスを消費する設備２０４とが設けられる。以下、管理サーバ２１０、給湯装置３００の具体的な構成について説明する。   The management server 210 is provided in the gas supply company and manages the gas consumption and the like of the entire predetermined management range (for example, town, ward, city, capital, road, prefecture, prefecture, etc.). The management range is provided with a facility 202 having the hot water supply device 300 and a facility 204 that does not have the hot water supply device 300 but consumes gas. Hereinafter, specific configurations of the management server 210 and the hot water supply apparatus 300 will be described.

管理サーバ２１０は、管理制御部２２０を含んで構成される。管理制御部２２０は、ＣＰＵ（中央処理装置）を含む半導体集積回路で構成され、ＲＯＭからＣＰＵ自体を動作させるためのプログラムやパラメータ等を読み出し、ワークエリアとしてのＲＡＭや他の電子回路と協働して管理サーバ２１０全体を管理および制御する。本実施形態において、管理制御部２２０は、管理通信部２２２、合計ガスデマンド導出部２２４、情報生成部２２６として機能する。   The management server 210 includes a management control unit 220. The management control unit 220 is composed of a semiconductor integrated circuit including a CPU (central processing unit), reads programs and parameters for operating the CPU itself from the ROM, and cooperates with the RAM as a work area and other electronic circuits. Thus, the entire management server 210 is managed and controlled. In the present embodiment, the management control unit 220 functions as a management communication unit 222, a total gas demand deriving unit 224, and an information generating unit 226.

管理通信部２２２は、管理範囲に設けられた全ての設備２０２、２０４それぞれと、通信を確立する。管理通信部２２２は、例えば、設備２０２、２０４のガス消費量を受信する。また、管理通信部２２２は、後述する運転促進情報（運転制御情報）および運転抑制情報（運転制御情報）を送信する。   The management communication unit 222 establishes communication with each of all the facilities 202 and 204 provided in the management range. For example, the management communication unit 222 receives gas consumption amounts of the facilities 202 and 204. In addition, the management communication unit 222 transmits driving promotion information (driving control information) and driving suppression information (driving control information) described later.

合計ガスデマンド導出部２２４は、管理通信部２２２が受信した設備２０２、２０４それぞれのガス消費量を合計して、合計ガスデマンド（管理範囲全体のガス消費量）を導出する。   The total gas demand deriving unit 224 adds up the gas consumption amounts of the facilities 202 and 204 received by the management communication unit 222 to derive the total gas demand (the gas consumption amount of the entire management range).

情報生成部２２６は、合計ガスデマンドと、ガス目標供給量とを、所定時間間隔（例えば、ｎ分ごと、ｎ時間ごと等）で比較する。情報生成部２２６は、合計ガスデマンドがガス目標供給量未満である場合、運転制御情報として運転促進情報を生成する。また、情報生成部２２６は、合計ガスデマンドがガス目標供給量を上回る場合、運転制御情報として運転抑制情報を生成する。そして、運転制御情報が生成されると、管理通信部２２２は、運転制御情報を給湯装置３００に送信する。   The information generation unit 226 compares the total gas demand with the target gas supply amount at predetermined time intervals (for example, every n minutes, every n hours, etc.). When the total gas demand is less than the target gas supply amount, the information generation unit 226 generates operation promotion information as operation control information. Moreover, the information generation part 226 produces | generates driving | operation suppression information as driving | operation control information, when a total gas demand exceeds a gas target supply amount. Then, when the operation control information is generated, the management communication unit 222 transmits the operation control information to the hot water supply device 300.

給湯装置３００は、ガス式給湯熱源機１１０と、電気式給湯熱源機１２０と、貯湯タンク１３０と、中央制御部３５０とを含んで構成される。   The hot water supply apparatus 300 includes a gas hot water supply heat source 110, an electric hot water supply heat source 120, a hot water storage tank 130, and a central control unit 350.

中央制御部３５０は、ＣＰＵ（中央処理装置）を含む半導体集積回路で構成され、ＲＯＭからＣＰＵ自体を動作させるためのプログラムやパラメータ等を読み出し、ワークエリアとしてのＲＡＭや他の電子回路と協働して給湯装置３００全体を管理および制御する。本実施形態において、中央制御部３５０は、装置通信部３５２、運転制御部３５４として機能する。   The central control unit 350 is composed of a semiconductor integrated circuit including a CPU (central processing unit), reads programs and parameters for operating the CPU itself from the ROM, and cooperates with the RAM as a work area and other electronic circuits. Thus, the entire hot water supply apparatus 300 is managed and controlled. In the present embodiment, the central control unit 350 functions as the device communication unit 352 and the operation control unit 354.

装置通信部３５２は、管理サーバ２１０と通信を確立し、例えば、ガス消費量を送信したり、運転制御情報を受信したりする。   The device communication unit 352 establishes communication with the management server 210, and transmits, for example, gas consumption or receives operation control information.

運転制御部３５４は、装置通信部３５２が運転制御情報を受信していない場合、要求熱量を満たすように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０それぞれの運転負荷を決定し、決定した運転負荷でガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転を制御する。   When the device communication unit 352 has not received the operation control information, the operation control unit 354 determines the operation loads of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 so as to satisfy the required heat amount. The operation of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 is controlled by the operating load.

一方、装置通信部３５２が運転制御情報として運転促進情報を受信すると、運転制御部３５４は、ガス式給湯熱源機１１０の運転負荷を増加させるとともに、要求熱量を満たすように電気式給湯熱源機１２０の運転負荷を低下させる。   On the other hand, when the device communication unit 352 receives the operation promotion information as the operation control information, the operation control unit 354 increases the operation load of the gas type hot water supply heat source device 110 and also satisfies the required heat amount. Reduce the operating load.

また、装置通信部３５２が運転制御情報として運転抑制情報を受信すると、運転制御部３５４は、ガス式給湯熱源機１１０の運転負荷を低下させるとともに、要求熱量を満たすように電気式給湯熱源機１２０の運転負荷を増加させる。   In addition, when the device communication unit 352 receives the operation suppression information as the operation control information, the operation control unit 354 reduces the operation load of the gas hot water supply heat source device 110 and also satisfies the required heat amount, so that the electric hot water supply heat source device 120 is satisfied. Increase the operating load.

以上説明したように、本実施形態にかかる給湯システム２００によれば、給湯装置３００の運転制御部３５４が、ガス供給会社に設けられた管理サーバ２１０が送信した運転制御情報に基づいて、ガス式給湯熱源機１１０の運転負荷を決定する。したがって、ガス供給会社が保有するガス供給設備の稼働率が所定値以上となるようにガス目標供給量を設定すれば、ガス供給設備全体の稼働率を向上させることができる。また、管理サーバ２１０が管理範囲全体のすべての給湯装置３００を一括して制御することができるため、合計ガスデマンドをガス目標供給量に容易に近づけることが可能となる。   As described above, according to the hot water supply system 200 according to the present embodiment, the operation control unit 354 of the hot water supply apparatus 300 is based on the operation control information transmitted from the management server 210 provided in the gas supply company. The operating load of the hot water supply heat source device 110 is determined. Therefore, if the target gas supply amount is set so that the operation rate of the gas supply facility owned by the gas supply company is equal to or higher than a predetermined value, the operation rate of the entire gas supply facility can be improved. Moreover, since the management server 210 can collectively control all the hot water supply apparatuses 300 in the entire management range, the total gas demand can be easily brought close to the target gas supply amount.

図９は、第４の実施形態にかかる給湯システム４００を説明する図である。なお、図９の給湯装置５００において、ガス、電力の流れを白抜き矢印で示し、水（給水、湯水等）の流れを実線の矢印で示し、信号の流れを破線で示す。 (4th Embodiment: Hot-water supply system 400)
FIG. 9 is a diagram illustrating a hot water supply system 400 according to the fourth embodiment. In the hot water supply apparatus 500 of FIG. 9, the flow of gas and electric power is indicated by white arrows, the flow of water (water supply, hot water, etc.) is indicated by solid arrows, and the flow of signals is indicated by broken lines.

図９に示すように、給湯システム４００は、管理サーバ４１０と、１または複数の給湯装置５００とを含んで構成される。なお、上述した給湯装置１００と実質的に等しい構成要素については、同一の符号を付して重複説明を省略する。   As shown in FIG. 9, the hot water supply system 400 includes a management server 410 and one or more hot water supply devices 500. In addition, about the component substantially equivalent to the hot-water supply apparatus 100 mentioned above, the same code | symbol is attached | subjected and duplication description is abbreviate | omitted.

管理サーバ４１０は、電力供給会社に設けられ、所定の管理範囲（例えば、町、区、市、都、道、府、県等）全体の電力消費量等を管理する。管理範囲には、給湯装置５００を有する設備４０２と、給湯装置５００を有しないものの電力を消費する設備４０４とが設けられる。以下、管理サーバ４１０、給湯装置５００の具体的な構成について説明する。   The management server 410 is provided in the power supply company and manages the power consumption of the entire predetermined management range (for example, town, ward, city, capital, road, prefecture, prefecture, etc.). In the management range, a facility 402 having the hot water supply device 500 and a facility 404 that does not have the hot water supply device 500 and consumes electric power are provided. Hereinafter, specific configurations of the management server 410 and the hot water supply apparatus 500 will be described.

管理サーバ４１０は、管理制御部４２０を含んで構成される。管理制御部４２０は、ＣＰＵ（中央処理装置）を含む半導体集積回路で構成され、ＲＯＭからＣＰＵ自体を動作させるためのプログラムやパラメータ等を読み出し、ワークエリアとしてのＲＡＭや他の電子回路と協働して管理サーバ４１０全体を管理および制御する。本実施形態において、管理制御部４２０は、管理通信部４２２、合計電力デマンド導出部４２４、情報生成部４２６として機能する。   The management server 410 includes a management control unit 420. The management control unit 420 is composed of a semiconductor integrated circuit including a CPU (Central Processing Unit), reads programs and parameters for operating the CPU itself from the ROM, and cooperates with the RAM as a work area and other electronic circuits. Thus, the entire management server 410 is managed and controlled. In the present embodiment, the management control unit 420 functions as a management communication unit 422, a total power demand derivation unit 424, and an information generation unit 426.

管理通信部４２２は、管理範囲に設けられた全ての設備４０２、４０４それぞれと、通信を確立する。管理通信部４２２は、例えば、設備４０２、４０４の電力消費量を受信する。また、管理通信部４２２は、後述する運転促進情報（運転制御情報）および運転抑制情報（運転制御情報）を送信する。   The management communication unit 422 establishes communication with each of all the facilities 402 and 404 provided in the management range. For example, the management communication unit 422 receives the power consumption of the facilities 402 and 404. In addition, the management communication unit 422 transmits driving promotion information (driving control information) and driving suppression information (driving control information) described later.

合計電力デマンド導出部４２４は、管理通信部４２２が受信した設備４０２、４０４それぞれの電力消費量を合計して、合計電力デマンド（管理範囲全体の電力消費量）を導出する。   The total power demand deriving unit 424 adds up the power consumption amounts of the facilities 402 and 404 received by the management communication unit 422 to derive the total power demand (the power consumption amount of the entire management range).

情報生成部４２６は、合計電力デマンドと、電力目標供給量とを、所定時間間隔（例えば、ｎ分ごと、ｎ時間ごと等）で比較する。情報生成部４２６は、合計電力デマンドが電力目標供給量未満である場合、運転制御情報として運転促進情報を生成する。また、情報生成部４２６は、合計電力デマンドが電力目標供給量を上回る場合、運転制御情報として運転抑制情報を生成する。そして、運転制御情報が生成されると、管理通信部４２２は、運転制御情報を給湯装置５００に送信する。   The information generation unit 426 compares the total power demand and the power target supply amount at predetermined time intervals (for example, every n minutes, every n hours, etc.). When the total power demand is less than the power target supply amount, the information generation unit 426 generates driving promotion information as driving control information. Moreover, the information generation part 426 produces | generates driving | operation suppression information as driving | operation control information, when a total electric power demand exceeds electric power target supply amount. Then, when the operation control information is generated, the management communication unit 422 transmits the operation control information to the hot water supply device 500.

給湯装置５００は、ガス式給湯熱源機１１０と、電気式給湯熱源機１２０と、貯湯タンク１３０と、中央制御部５５０とを含んで構成される。   The hot water supply device 500 includes a gas hot water supply heat source 110, an electric hot water supply heat source 120, a hot water storage tank 130, and a central control unit 550.

中央制御部５５０は、ＣＰＵ（中央処理装置）を含む半導体集積回路で構成され、ＲＯＭからＣＰＵ自体を動作させるためのプログラムやパラメータ等を読み出し、ワークエリアとしてのＲＡＭや他の電子回路と協働して給湯装置５００全体を管理および制御する。本実施形態において、中央制御部５５０は、装置通信部５５２、運転制御部５５４として機能する。   The central control unit 550 is composed of a semiconductor integrated circuit including a CPU (Central Processing Unit), reads programs and parameters for operating the CPU itself from the ROM, and cooperates with the RAM as a work area and other electronic circuits. Thus, the entire hot water supply apparatus 500 is managed and controlled. In the present embodiment, the central control unit 550 functions as the device communication unit 552 and the operation control unit 554.

装置通信部５５２は、管理サーバ４１０と通信を確立し、例えば、電力消費量を送信したり、運転制御情報を受信したりする。   The device communication unit 552 establishes communication with the management server 410, and transmits, for example, power consumption or receives operation control information.

運転制御部５５４は、装置通信部５５２が運転制御情報を受信していない場合、要求熱量を満たすように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０それぞれの運転負荷を決定し、決定した運転負荷でガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転を制御する。   When the device communication unit 552 has not received the operation control information, the operation control unit 554 determines the operation loads of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 so as to satisfy the required heat amount. The operation of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 is controlled by the operating load.

一方、装置通信部５５２が運転制御情報として運転促進情報を受信すると、運転制御部５５４は、電気式給湯熱源機１２０の運転負荷を増加させるとともに、要求熱量を満たすようにガス式給湯熱源機１１０の運転負荷を低下させる。   On the other hand, when the device communication unit 552 receives the operation promotion information as the operation control information, the operation control unit 554 increases the operation load of the electric hot water supply heat source device 120 and also satisfies the required heat amount with the gas hot water supply heat source device 110. Reduce the operating load.

また、装置通信部５５２が運転制御情報として運転抑制情報を受信すると、運転制御部５５４は、電気式給湯熱源機１２０の運転負荷を低下させるとともに、要求熱量を満たすようにガス式給湯熱源機１１０の運転負荷を増加させる。   In addition, when the device communication unit 552 receives the operation suppression information as the operation control information, the operation control unit 554 reduces the operation load of the electric hot water supply heat source device 120 and also satisfies the required heat amount with the gas hot water supply heat source device 110. Increase the operating load.

以上説明したように、本実施形態にかかる給湯システム４００によれば、給湯装置５００の運転制御部５５４が、電力供給会社に設けられた管理サーバ４１０が送信した運転制御情報に基づいて、電気式給湯熱源機１２０の運転負荷を決定する。したがって、電力供給会社が保有する電力供給設備の稼働率が所定値以上となるように電力目標供給量を設定すれば、電力供給設備全体の稼働率を向上させることができる。また、管理サーバ４１０が管理範囲全体のすべての給湯装置５００を一括して制御することができるため、合計電力デマンドを電力目標供給量に容易に近づけることが可能となる。   As described above, according to the hot water supply system 400 according to the present embodiment, the operation control unit 554 of the hot water supply apparatus 500 is based on the operation control information transmitted from the management server 410 provided in the power supply company. The operating load of the hot water supply heat source unit 120 is determined. Therefore, if the power target supply amount is set so that the operation rate of the power supply equipment owned by the power supply company is equal to or greater than a predetermined value, the operation rate of the entire power supply facility can be improved. In addition, since the management server 410 can collectively control all the hot water supply apparatuses 500 in the entire management range, the total power demand can be easily brought close to the power target supply amount.

以上、添付図面を参照しながら本発明の好適な実施形態について説明したが、本発明はかかる実施形態に限定されないことは言うまでもない。当業者であれば、特許請求の範囲に記載された範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。   As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

例えば、上記第１の実施形態において、運転制御部１５４は、ガスデマンドがガス目標供給量となるように、ガス式給湯熱源機１１０の運転負荷を調整する構成を例に挙げて説明した。しかし、運転制御部１５４は、ガス式給湯熱源機１１０が消費するガスの消費量（ガス式給湯熱源機１１０へのガスの供給量）がガス目標供給量となるように、ガス式給湯熱源機１１０の運転負荷を制御してもよい。   For example, in the first embodiment, the operation control unit 154 has been described with an example of a configuration in which the operation load of the gas hot water supply heat source device 110 is adjusted so that the gas demand becomes the gas target supply amount. However, the operation control unit 154 is configured so that the gas consumption amount of the gas consumed by the gas-type hot water supply heat source device 110 (the gas supply amount to the gas-type hot water supply heat source device 110) becomes the gas target supply amount. 110 operating loads may be controlled.

また、上記第１、第２の実施形態において、給湯装置１００が装置通信部１５２を備える構成を例に挙げて説明した。しかし、ガス目標情報、電力目標情報が、給湯装置１００の不図示のメモリに予め保持されている場合、装置通信部１５２を備えずともよい。   Moreover, in the said 1st, 2nd embodiment, the hot water supply apparatus 100 demonstrated and demonstrated the structure provided with the apparatus communication part 152 as an example. However, when the gas target information and the power target information are stored in advance in a memory (not shown) of the hot water supply apparatus 100, the apparatus communication unit 152 may not be provided.

また、上記第２の実施形態において、運転制御部１５４が、ガス差分と、補正電力差分とが所定の範囲内に収まるように（例えば、ガス差分の９５％〜１０５％の範囲内に補正電力差分が収まるように）、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定する構成を例に挙げて説明した。しかし、運転制御部１５４は、ガス差分と、補正電力差分とが実質的に等しくなるように、ガス式給湯熱源機１１０および電気式給湯熱源機１２０の運転負荷を決定するとしてもよい。   In the second embodiment, the operation control unit 154 causes the correction power to be within a predetermined range between the gas difference and the correction power difference (for example, 95% to 105% of the gas difference). The configuration for determining the operation loads of the gas hot water supply heat source 110 and the electric hot water supply heat source 120 has been described as an example so that the difference is settled. However, the operation control unit 154 may determine the operation loads of the gas hot water supply heat source device 110 and the electric hot water supply heat source device 120 so that the gas difference and the corrected power difference are substantially equal.

また、上記第３の実施形態において、装置通信部３５２が運転抑制情報を受信した場合、運転制御部３５４が、必ず、ガス式給湯熱源機１１０の運転負荷を低下させる構成を例に挙げて説明した。しかし、装置通信部３５２が運転抑制情報を受信したとしても、運転制御部３５４は、ガス式給湯熱源機１１０の運転負荷を低下させずともよい。例えば、運転抑制情報を受信した場合に、ガス式給湯熱源機１１０の運転負荷を低下させると、インセンティブ（例えば、ガス料金の低減、対価）を得ることができるように構成し、ガス式給湯熱源機１１０の運転負荷を低下させないと、ペナルティ（例えば、ガス料金の増額）が課されるように構成してもよい。そして、給湯装置３００は、インセンティブとペナルティとに基づいて、ガス式給湯熱源機１１０と電気式給湯熱源機１２０の運転負荷を決定するとしてもよい。   Moreover, in the said 3rd Embodiment, when the apparatus communication part 352 receives driving | running | working suppression information, it demonstrates and mentions as an example the structure by which the driving | running control part 354 always reduces the driving | running load of the gas type hot water supply heat source machine 110. did. However, even if the device communication unit 352 receives the operation suppression information, the operation control unit 354 may not reduce the operation load of the gas hot water supply heat source unit 110. For example, when the operation suppression information is received, if the operation load of the gas hot water supply heat source device 110 is reduced, an incentive (for example, reduction in gas charge, consideration) can be obtained, and the gas hot water supply heat source is configured. If the operating load of the machine 110 is not reduced, a penalty (for example, an increase in gas charge) may be imposed. And hot water supply apparatus 300 may determine the operation load of gas type hot water supply heat source machine 110 and electric type hot water supply heat source machine 120 based on an incentive and a penalty.

また、管理サーバ２１０の情報生成部２２６が、合計ガスデマンドおよびガス目標供給量に基づいて、給湯装置３００が有するガス式給湯熱源機１１０の運転負荷を決定し、運転負荷を示す情報を運転制御情報として生成してもよい。この場合、給湯装置３００の装置通信部３５２が運転制御情報を受信すると、運転制御部３５４は、運転制御情報に示された運転負荷に基づいてガス式給湯熱源機１１０の運転を制御するとしてもよい。   In addition, the information generation unit 226 of the management server 210 determines an operation load of the gas hot water supply heat source device 110 included in the hot water supply device 300 based on the total gas demand and the gas target supply amount, and controls information indicating the operation load. It may be generated as information. In this case, when the device communication unit 352 of the hot water supply device 300 receives the operation control information, the operation control unit 354 may control the operation of the gas hot water supply heat source 110 based on the operation load indicated in the operation control information.

また、上記第４の実施形態において、装置通信部５５２が運転抑制情報を受信した場合、運転制御部５５４が、必ず、電気式給湯熱源機１２０の運転負荷を低下させる構成を例に挙げて説明した。しかし、装置通信部５５２が運転抑制情報を受信したとしても、運転制御部５５４は、電気式給湯熱源機１２０の運転負荷を低下させずともよい。例えば、運転抑制情報を受信した場合に、電気式給湯熱源機１２０の運転負荷を低下させると、インセンティブ（例えば、電気料金の低減、対価）を得ることができるように構成し、電気式給湯熱源機１２０の運転負荷を低下させないと、ペナルティ（例えば、電気料金の増額）が課されるように構成してもよい。そして、給湯装置５００は、インセンティブとペナルティとに基づいて、ガス式給湯熱源機１１０と電気式給湯熱源機１２０の運転負荷を決定するとしてもよい。   Moreover, in the said 4th Embodiment, when the apparatus communication part 552 receives driving | running | working suppression information, it demonstrates and mentions as an example the structure by which the driving | running control part 554 always reduces the driving load of the electric hot water supply heat source machine 120. did. However, even if the device communication unit 552 receives the operation suppression information, the operation control unit 554 does not need to reduce the operation load of the electric hot water supply heat source unit 120. For example, when the operation suppression information is received, if the operation load of the electric hot water supply heat source unit 120 is reduced, an incentive (e.g., reduction in electric charges, consideration) can be obtained, and the electric hot water supply heat source is configured. If the operation load of the machine 120 is not reduced, a penalty (for example, an increase in the electricity bill) may be imposed. And hot water supply apparatus 500 may determine the operation load of gas type hot water supply heat source machine 110 and electric type hot water supply heat source machine 120 based on an incentive and a penalty.

また、管理サーバ４１０の情報生成部４２６が、合計電力デマンドおよび電力目標供給量に基づいて、給湯装置５００が有する電気式給湯熱源機１２０の運転負荷を決定し、運転負荷を示す情報を運転制御情報として生成してもよい。この場合、給湯装置５００の装置通信部５５２が運転制御情報を受信すると、運転制御部５５４は、運転制御情報に示された運転負荷に基づいて電気式給湯熱源機１２０の運転を制御するとしてもよい。   In addition, the information generation unit 426 of the management server 410 determines an operation load of the electric hot water supply heat source device 120 included in the hot water supply device 500 based on the total power demand and the target power supply amount, and controls the information indicating the operation load. It may be generated as information. In this case, when the device communication unit 552 of the hot water supply device 500 receives the operation control information, the operation control unit 554 controls the operation of the electric hot water supply heat source device 120 based on the operation load indicated in the operation control information. Good.

また、上記実施形態において、運転負荷を低下させる構成を例に挙げて説明したが、運転負荷の低下には、運転停止も含まれる。   Moreover, in the said embodiment, although the structure which reduces driving | running load was mentioned as an example, the stop of driving | running | working is also included in the fall of driving | running load.
