For example, the processing device 37 has functions of a determination unit 371 and a control unit 372 described later.
　判断部３７１は、空調機器２が設定操作に応じて設定を変更してから、予め決められた一定時間、空調機器２の設定が一定である状態が継続したときに空調機器２が安定動作になったと判断する。本実施形態では、判断部３７１は、第２の通信部３２で状態変化情報が受信されてから当該一定時間が経過するまでに第２の通信部３２で新しい状態変化情報が受信されなかったときに、空調機器２が安定動作になったと判断する。 After the air conditioner 2 changes the setting according to the setting operation, the determination unit 371 causes the air conditioner 2 to operate stably when the state where the setting of the air conditioner 2 is constant is continued for a predetermined time. Judge that it became. In the present embodiment, when the second communication unit 32 does not receive new state change information from the time when the second communication unit 32 receives the state change information until the predetermined time elapses. In addition, it is determined that the air conditioner 2 has operated stably.

　ところで、処理装置３７は、状態変化情報を取得したときに、状態変化情報の内容（ユーザの設定操作）が非省エネルギー操作である場合、エネルギー状態を非省エネルギー状態に設定する。一方、状態変化情報の内容（ユーザの設定操作）が省エネルギー操作である場合、処理装置３７は、非省エネルギー状態を解除する。処理装置３７の制御部３７２は、エネルギー状態が非省エネルギー状態である場合に空調機器２が安定動作になったと判断部３７１で判断されると、省エネルギー制御を行う。 By the way, when the state change information is acquired and the content of the state change information (user setting operation) is a non-energy saving operation, the processing device 37 sets the energy state to the non-energy saving state. On the other hand, when the content of the state change information (user setting operation) is an energy saving operation, the processing device 37 cancels the non-energy saving state. The control unit 372 of the processing device 37 performs the energy saving control when the determination unit 371 determines that the air conditioner 2 is in a stable operation when the energy state is the non-energy saving state.
　省エネルギー操作と非省エネルギー操作は、例えば設定温度などで予め区分されている。例えば、省エネルギー操作には、冷房運転時の設定温度を２８度以上の範囲に設定する操作、暖房運転時の設定温度を２０度以下の範囲に設定する操作、送風に設定する操作などがある。非省エネルギー操作には、冷房運転時の設定温度を２８度未満の範囲にする操作、暖房運転時の設定温度を２０度より高い範囲に設定する操作などがある。 The energy saving operation and the non-energy saving operation are classified in advance by, for example, a set temperature. For example, the energy saving operation includes an operation for setting the set temperature during the cooling operation to a range of 28 degrees or more, an operation for setting the set temperature during the heating operation to a range of 20 degrees or less, and an operation for setting the air blowing. Non-energy saving operations include an operation for setting the set temperature during cooling operation to a range of less than 28 degrees, and an operation for setting the set temperature during heating operation to a range higher than 20 degrees.
　なお、コントローラ側記憶部３５には、コンピュータである省エネルギー装置３が各種の機能を実行するためのプログラムが格納されている。つまり、コントローラ側記憶部３５には、省エネルギー装置３の処理装置３７を、判断部３７１および制御部３７２として機能させるためのプログラムが格納されている。 The controller-side storage unit 35 stores programs for the energy saving device 3 that is a computer to execute various functions. That is, the controller-side storage unit 35 stores a program for causing the processing device 37 of the energy saving apparatus 3 to function as the determination unit 371 and the control unit 372.
　次に、本実施形態に係る省エネルギーシステム１の動作について図６を用いて説明する。ユーザは、空調機器２の付属リモコン２４により、空調機器２のオンオフ、モード（冷房運転、暖房運転、除湿運転など）および温度設定などの操作を行ったり、表示器５を用いて空調機器２の設定状態をモニタしたりしている。ここでは、冷房運転において、ユーザがオン操作および設定温度を２５度とする設定操作を行った場合について説明する。 Next, the operation of the energy saving system 1 according to the present embodiment will be described with reference to FIG. The user performs operations such as on / off of the air conditioner 2, mode (cooling operation, heating operation, dehumidifying operation, etc.) and temperature setting with the attached remote controller 24 of the air conditioner 2, and the display 5 is used to set the air conditioner 2. The setting status is monitored. Here, a case where the user performs an on operation and a setting operation for setting the set temperature to 25 degrees in the cooling operation will be described.
　空調機器２は、空調機器２の設定を変更するための設定操作（機器オン、設定温度２５度）を付属リモコン２４から受け付ける。当該設定操作を受け付けると、空調機器２は、設定操作の内容に応じて空調機器２の設定を変更する。当該設定操作によって空調機器２の設定を変更すると、空調機器２は、空調機器２の設定変更の内容（機器オン、設定温度２５度）を表わす状態変化情報を省エネルギー装置３に出力する。 The air conditioning device 2 receives a setting operation (device on, set temperature 25 degrees) for changing the setting of the air conditioning device 2 from the attached remote controller 24. When receiving the setting operation, the air conditioner 2 changes the setting of the air conditioner 2 according to the content of the setting operation. When the setting of the air conditioner 2 is changed by the setting operation, the air conditioner 2 outputs to the energy saving apparatus 3 state change information indicating the contents of the setting change of the air conditioner 2 (equipment on, set temperature 25 degrees).
　その後、省エネルギー装置３は、空調機器２から状態変化情報を受け取った場合（Ｓ１の「Ｙｅｓ」）、状態変化情報を空調状態格納エリア３５１に格納し、空調状態格納エリア３５１に格納されている状態変化情報ごとに、状態変化情報を格納した格納時刻（現在時刻）を表わす時刻情報を安定状態格納エリア３５２に格納する（Ｓ２）。必要に応じて、省エネルギー装置３は、状態変化情報を表示器５に出力し、表示器５は、状態変化情報の内容（空調機器２の設定状態）を表示する。 After that, when the energy saving apparatus 3 receives the state change information from the air conditioner 2 (“Yes” in S1), the state saving information is stored in the air conditioning state storage area 351 and is stored in the air conditioning state storage area 351. For each change information, time information indicating the storage time (current time) at which the state change information is stored is stored in the stable state storage area 352 (S2). If necessary, the energy saving device 3 outputs state change information to the display 5, and the display 5 displays the contents of the state change information (setting state of the air conditioner 2).
　ユーザの操作が非省エネルギー操作である場合（Ｓ３）、省エネルギー装置３は、エネルギー状態を非省エネルギー状態に設定する（Ｓ４）。一方、ユーザの操作が省エネルギー操作である場合（Ｓ３）、省エネルギー装置３は、非省エネルギー状態を解除する（Ｓ５）。ステップＳ４またはステップＳ５の実行後、ステップＳ１に戻る。なお、ユーザの操作が例えばオフ操作などである場合（Ｓ３）、動作を終了する。 When the user's operation is a non-energy saving operation (S3), the energy saving device 3 sets the energy state to a non-energy saving state (S4). On the other hand, when the user's operation is an energy saving operation (S3), the energy saving apparatus 3 cancels the non-energy saving state (S5). After executing step S4 or step S5, the process returns to step S1. If the user operation is an off operation, for example (S3), the operation is terminated.
　空調機器２の設定状態に変化がない場合（Ｓ１の「Ｎｏ」）、省エネルギー装置３は、空調状態格納エリア３５１に格納されている最新の設定状態を参照する。エネルギー状態が非省エネルギー状態である場合（Ｓ６の「Ｙｅｓ」）、現在時刻と、最新の設定状態に対応して安定状態格納エリア３５２に格納されている格納時刻との差分が、判定値格納エリア３５３に格納されている閾値を超えていると（Ｓ７の「Ｙｅｓ」）、省エネルギー装置３は、例えば空調機器２の設定温度を２８度に設定するように省エネルギー制御を行う（Ｓ８）。その後、省エネルギー装置３は、非省エネルギー状態を解除する（Ｓ９）。なお、ステップＳ６において、エネルギー状態が非省エネルギー状態ではない場合（Ｓ６の「Ｎｏ」）、ステップＳ７において、上記差分が閾値以下である場合（Ｓ７の「Ｎｏ」）、ステップＳ１に戻る。 When there is no change in the setting state of the air conditioner 2 (“No” in S1), the energy saving apparatus 3 refers to the latest setting state stored in the air conditioning state storage area 351. When the energy state is a non-energy saving state (“Yes” in S6), the difference between the current time and the storage time stored in the stable state storage area 352 corresponding to the latest set state is the determination value storage area. If the threshold stored in 353 is exceeded (“Yes” in S7), the energy saving apparatus 3 performs energy saving control so that, for example, the set temperature of the air conditioner 2 is set to 28 degrees (S8). Thereafter, the energy saving apparatus 3 cancels the non-energy saving state (S9). In step S6, if the energy state is not a non-energy saving state (“No” in S6), if the difference is equal to or less than the threshold value in step S7 (“No” in S7), the process returns to step S1.
　なお、冬季（暖房運転）の場合、２０度が一般的な省エネルギー温度であり、省エネルギー装置３は、上記温度を基準として省エネルギー制御を行う。 In the winter season (heating operation), 20 degrees is a general energy saving temperature, and the energy saving apparatus 3 performs energy saving control based on the above temperature.
　以上説明した本実施形態の省エネルギーシステム１では、ユーザの非省エネルギー操作に対して、空調機器２が安定動作になった後、空調機器２の負荷を緩和する方向へ空調機器２の設定を変更するので、ユーザの反感を招くことなく省エネルギー化を図ることができる。すなわち、空調機器２が安定動作になったことを、ユーザの設定操作に応じて空調機器２の設定を変更したことへの充足感の達成と判断することで、その後、空調機器２の設定の緩和（例えば冷房運転の場合に２５度から２８度に変更すること）を行っても、ユーザの反感を招くことがない。 In the energy saving system 1 of the present embodiment described above, after the air conditioner 2 becomes stable with respect to the user's non-energy saving operation, the setting of the air conditioner 2 is changed in a direction to ease the load on the air conditioner 2. Therefore, energy saving can be achieved without inviting the user's feeling. That is, by determining that the air conditioner 2 is in a stable operation as fulfillment of satisfaction with changing the setting of the air conditioner 2 according to the user's setting operation, the setting of the air conditioner 2 is thereafter performed. Even if mitigation (for example, changing from 25 degrees to 28 degrees in the case of cooling operation) is performed, the user will not feel dislike.
　また、本実施形態の省エネルギーシステム１では、空調機器２の安定動作を空調機器２の状態変更を表わす状態変化情報の受信によって判断するので、特別な装置（例えば室内温度計）が不要である。本実施形態では、空調機器２の状態監視に使用している表示器５への状態変化情報の通知が一定時間ないことをもって、空調機器２が安定動作になったと判断することができる。 Further, in the energy saving system 1 of the present embodiment, since the stable operation of the air conditioner 2 is determined by receiving the state change information indicating the state change of the air conditioner 2, no special device (for example, an indoor thermometer) is necessary. In the present embodiment, it is possible to determine that the air conditioner 2 has performed a stable operation when there is no notification of the state change information to the display 5 used for the status monitoring of the air conditioner 2 for a certain period of time.
　（実施形態２）
　実施形態２に係る省エネルギーシステム１は、空調機器２の使用電力の低下に応じて省エネルギー制御を行う点で、実施形態１に係る省エネルギーシステム１と相違する。なお、実施形態１の省エネルギーシステム１と同様の構成要素については、同一の符号を付して説明を省略する。 (Embodiment 2)
The energy saving system 1 according to the second embodiment is different from the energy saving system 1 according to the first embodiment in that energy saving control is performed in accordance with a decrease in power consumption of the air conditioner 2. In addition, about the component similar to the energy saving system 1 of Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　本実施形態の判断部３７１は、空調機器２が設定操作に応じて設定を変更してから、空調機器２の使用電力が低下した状態が一定時間継続したときに、空調機器２が安定動作になったと判断する。 The determination unit 371 according to the present embodiment causes the air conditioner 2 to operate stably when the state in which the power consumption of the air conditioner 2 is reduced continues for a certain time after the air conditioner 2 changes the setting according to the setting operation. Judge that it became.
　次に、本実施形態に係る省エネルギーシステム１の動作について説明する。ユーザは、空調機器２の付属リモコン２４により、空調機器２のオンオフ、モード（冷房運転、暖房運転、除湿運転など）および温度設定などの操作を行ったり、表示器５を用いて空調機器２の設定状態をモニタしたりしている。ここでは、冷房運転において、ユーザがオン操作および設定温度を２５度とする設定操作を行った場合について説明する。 Next, the operation of the energy saving system 1 according to this embodiment will be described. The user performs operations such as on / off of the air conditioner 2, mode (cooling operation, heating operation, dehumidifying operation, etc.) and temperature setting with the attached remote controller 24 of the air conditioner 2, and the display 5 is used to set the air conditioner 2. The setting status is monitored. Here, a case where the user performs an on operation and a setting operation for setting the set temperature to 25 degrees in the cooling operation will be described.
　まず、省エネルギー装置３は、電力計測ユニット４２から使用電力情報を受け取り、使用電力情報を電力計測値格納エリア３５４に格納する。必要に応じて、省エネルギー装置３は、使用電力情報を表示器５に出力し、表示器５は、使用電力を表示する。 First, the energy saving apparatus 3 receives power usage information from the power measurement unit 42 and stores the power usage information in the power measurement value storage area 354. If necessary, the energy saving apparatus 3 outputs power usage information to the display 5 and the display 5 displays the power usage.
　その後、空調機器２は、設定操作（機器オン、設定温度２５度）を付属リモコン２４から受け付けると、設定操作の内容に応じて空調機器２の設定を変更する。設定操作によって空調機器２の設定を変更すると、空調機器２は、設定変更の内容（機器オン、設定温度２５度）を表わす状態変化情報を省エネルギー装置３に出力する。 After that, when the air conditioning device 2 receives a setting operation (device on, set temperature 25 degrees) from the attached remote controller 24, the setting of the air conditioning device 2 is changed according to the content of the setting operation. When the setting of the air conditioner 2 is changed by the setting operation, the air conditioner 2 outputs state change information representing the contents of the setting change (device on, set temperature 25 degrees) to the energy saving device 3.
　省エネルギー装置３は、空調機器２から状態変化情報を受け取ると、状態変化情報をトリガとして、電力計測値格納エリア３５４の使用電力情報の監視を開始し、使用電力が一定量以上低下した状態が一定時間以上継続した場合、例えば空調機器２の設定温度を２８度に設定するように、空調機器２の負荷を緩和する方向へ空調機器２の設定を変更する。 When the energy saving device 3 receives the state change information from the air conditioner 2, it starts monitoring the power usage information in the power measurement value storage area 354 using the state change information as a trigger, and the state where the power usage has decreased by a certain amount is constant. When it continues for more than the time, for example, the setting of the air conditioner 2 is changed so as to reduce the load of the air conditioner 2 so that the set temperature of the air conditioner 2 is set to 28 degrees.
　一例として、図７の場合について説明する。省エネルギー装置３は、期間Ｔ１では継続時間が短いので、期間Ｔ１の後に省エネルギー制御を行わないが、期間Ｔ２では継続時間が一定時間以上であるため、期間Ｔ２の後に省エネルギー制御を行う。省エネルギー装置３は、使用電力（１分間の使用電力量）が下がったタイミング（時刻ｔ２）で安定状態格納エリア３５２に時刻ｔ２を格納し、一定の時間間隔で現在時刻と格納時刻（時刻ｔ２）との差分を求め、この差分が判定値格納エリア３５３の閾値よりも大きければ省エネルギー制御を行う。図７では、上記差分が閾値よりも大きくなる前に、時刻ｔ３で使用電力の低減があったので、省エネルギー装置３は、安定状態格納エリア３５２に時刻ｔ３を上書きし、現在時刻と格納時刻（時刻ｔ３）との差分が閾値（期間Ｔ２）を超えた時点（時刻ｔ４）で、省エネルギー制御を行う。 As an example, the case of FIG. 7 will be described. The energy saving apparatus 3 does not perform energy saving control after the period T1 because the duration is short in the period T1, but performs energy saving control after the period T2 because the duration is longer than a certain time in the period T2. The energy saving device 3 stores the time t2 in the stable state storage area 352 at the timing (time t2) when the power consumption (power consumption for one minute) decreases, and the current time and the storage time (time t2) at regular time intervals. If the difference is larger than the threshold value of the determination value storage area 353, energy saving control is performed. In FIG. 7, before the difference becomes larger than the threshold value, the power consumption has been reduced at time t3. Therefore, the energy saving apparatus 3 overwrites the stable state storage area 352 with time t3, and the current time and storage time ( Energy saving control is performed at the time (time t4) when the difference from time t3) exceeds the threshold value (period T2).
　以上説明した本実施形態の省エネルギーシステム１では、空調機器２の安定動作を空調機器２の使用電力の推移によって判断するため、特別な装置（例えば室内温度計）が不要である。本実施形態では、空調機器２の使用電力の見える化に用いられる電力計測ユニット４２からの使用電力情報の推移をもって空調機器２の安定動作を判断することができる。 In the energy saving system 1 of the present embodiment described above, a special device (for example, an indoor thermometer) is not necessary because the stable operation of the air conditioner 2 is determined based on the transition of the electric power used by the air conditioner 2. In the present embodiment, the stable operation of the air conditioner 2 can be determined based on the transition of the used power information from the power measurement unit 42 used for visualizing the power used by the air conditioner 2.
　なお、本実施形態の判断部３７１は、空調機器２の使用電力が低下した状態が一定時間継続したときに、空調機器２が安定動作になったと判断しているが、本実施形態の変形例として、判断部３７１は、空調機器２の使用電力が低下した時点で、空調機器２が安定動作になったと判断してもよい。 Note that the determination unit 371 of the present embodiment determines that the air conditioner 2 is in a stable operation when the state where the power consumption of the air conditioner 2 is reduced continues for a certain period of time. As such, the determination unit 371 may determine that the air conditioner 2 has performed a stable operation when the power used by the air conditioner 2 has decreased.
　（実施形態３）
　実施形態３に係る省エネルギーシステム１は、ユーザの合意を確認してから省エネルギー制御を行う点で、実施形態１に係る省エネルギーシステム１と相違する。なお、実施形態１の省エネルギーシステム１と同様の構成要素については、同一の符号を付して説明を省略する。 (Embodiment 3)
The energy saving system 1 according to the third embodiment is different from the energy saving system 1 according to the first embodiment in that energy saving control is performed after the user's agreement is confirmed. In addition, about the component similar to the energy saving system 1 of Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　本実施形態の省エネルギー装置３の処理装置３７は、空調機器２に対して省エネルギー制御を行うことについてユーザの合意を確認する確認部（図示せず）の機能をさらに有している。 The processing device 37 of the energy saving apparatus 3 of the present embodiment further has a function of a confirmation unit (not shown) that confirms the user's agreement about performing energy saving control on the air conditioner 2.
　確認部は、空調機器２が安定動作になったと判断部３７１で判断された場合に、図８に示すような問い合わせ画面５６を表示するように表示器５を制御する。表示器５は、確認部の指示に従って、問い合わせ画面５６をモニタ部５２に表示する。ユーザから合意の操作が行われると、表示器５は、合意操作が行われたことを示す合意情報を省エネルギー装置３に出力する。確認部は、合意情報を受け取って、ユーザの合意を確認する。 The confirmation unit controls the display 5 so as to display the inquiry screen 56 as shown in FIG. 8 when the determination unit 371 determines that the air conditioner 2 is in a stable operation. The display 5 displays an inquiry screen 56 on the monitor unit 52 in accordance with the instruction from the confirmation unit. When an agreement operation is performed by the user, the display 5 outputs agreement information indicating that the agreement operation has been performed to the energy saving apparatus 3. The confirmation unit receives the agreement information and confirms the user's agreement.
　本実施形態の制御部３７２は、空調機器２が安定動作になったと判断部３７１で判断された場合に、確認部でユーザの合意が確認されると、省エネルギー制御を行う。なお、実施形態１の制御部３７２と同様の機能については説明を省略する。 The control unit 372 according to the present embodiment performs energy saving control when the confirmation unit confirms the user's agreement when the determination unit 371 determines that the air-conditioning apparatus 2 is in a stable operation. Note that description of functions similar to those of the control unit 372 of the first embodiment is omitted.
　以上説明した本実施形態の省エネルギーシステム１では、空調機器２が安定動作になったことを判断した後、省エネルギー制御についてユーザの合意を確認することによって、空調機器２が勝手に制御されたという反感を抑えることができる。 In the energy saving system 1 of the present embodiment described above, after determining that the air conditioner 2 is in a stable operation, the user feels that the air conditioner 2 has been controlled without permission by confirming the user's agreement on the energy saving control. Can be suppressed.
　なお、本実施形態の変形例として、複数のユーザの合意が確認されたときに、省エネルギー装置３は、省エネルギー制御を行ってもよい。本変形例において、複数のユーザの合意は、ユーザ全員の合意であってもよいし、過半数のユーザの合意であってもよい。 As a modification of the present embodiment, the energy saving device 3 may perform energy saving control when the agreement of a plurality of users is confirmed. In this modification, the agreement of a plurality of users may be the agreement of all the users, or may be the agreement of a majority of users.
　（実施形態４）
　実施形態４に係る省エネルギーシステム１は、省エネルギー制御の実行回数を制限する点で、実施形態１に係る省エネルギーシステム１と相違する。なお、実施形態１の省エネルギーシステム１と同様の構成要素については、同一の符号を付して説明を省略する。 (Embodiment 4)
The energy saving system 1 according to the fourth embodiment is different from the energy saving system 1 according to the first embodiment in that the number of execution times of energy saving control is limited. In addition, about the component similar to the energy saving system 1 of Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　本実施形態の省エネルギー装置３の処理装置３７は、図９に示すように、省エネルギー制御の実行回数をカウントする回数カウント部３７３をさらに備えている。回数カウント部３７３は、空調機器２の電源がオンになった後からの省エネルギー制御の実行回数をカウントする
　本実施形態の制御部３７２は、空調機器２が安定動作になったと判断部３７１で判断された場合に、回数カウント部３７３でカウントされた実行回数が制限回数以下であると、省エネルギー制御を行う。一方、回数カウント部３７３でカウントされた実行回数が制御回数制限値を超えると、制御部３７２は、省エネルギー制御を行わない。制御部３７２で用いられる制限回数は、コントローラ側記憶部３５の制限回数格納エリア３５５に格納されている。なお、実施形態１の制御部３７２と同様の機能については説明を省略する。 As illustrated in FIG. 9, the processing device 37 of the energy saving device 3 of the present embodiment further includes a number counting unit 373 that counts the number of execution times of energy saving control. The number counting unit 373 counts the number of executions of energy saving control after the power supply of the air conditioner 2 is turned on. The control unit 372 according to the present embodiment determines that the air conditioner 2 has a stable operation by the determining unit 371 In such a case, if the number of executions counted by the number counting unit 373 is equal to or less than the limit number, energy saving control is performed. On the other hand, when the number of executions counted by the number counting unit 373 exceeds the control number limit value, the control unit 372 does not perform energy saving control. The limit number used by the control unit 372 is stored in the limit number storage area 355 of the controller-side storage unit 35. Note that description of functions similar to those of the control unit 372 of the first embodiment is omitted.
　次に、本実施形態に係る省エネルギーシステム１の動作について図１０を用いて説明する。省エネルギー装置３は、空調機器２から状態変化情報を受け取った場合（Ｓ１１の「Ｙｅｓ」）、状態変化情報を空調状態格納エリア３５１に格納し、空調状態格納エリア３５１に格納されている状態変化情報ごとに、状態変化情報を格納した格納時刻（現在時刻）を表わす時刻情報を安定状態格納エリア３５２に格納する（Ｓ１２）。必要に応じて、省エネルギー装置３は、状態変化情報を表示器５に出力し、表示器５は、状態変化情報の内容（空調機器２の設定状態）を表示する。 Next, the operation of the energy saving system 1 according to the present embodiment will be described with reference to FIG. When the energy saving device 3 receives the state change information from the air conditioner 2 (“Yes” in S11), the state change information is stored in the air conditioning state storage area 351, and the state change information stored in the air conditioning state storage area 351 is stored. Every time, the time information indicating the storage time (current time) at which the state change information is stored is stored in the stable state storage area 352 (S12). If necessary, the energy saving device 3 outputs state change information to the display 5, and the display 5 displays the contents of the state change information (setting state of the air conditioner 2).
　ユーザの操作が非省エネルギー操作である場合（Ｓ１３）、省エネルギー装置３は、エネルギー状態を非省エネルギー状態に設定する（Ｓ１４）。一方、ユーザの操作が省エネルギー操作である場合（Ｓ１３）、省エネルギー装置３は、非省エネルギー状態を解除する（Ｓ１５）。ステップＳ１４またはステップＳ１５の実行後、ステップＳ１１に戻る。なお、ユーザの操作が例えばオフ操作などである場合（Ｓ１６の「Ｙｅｓ」）、省エネルギー制御の実行回数をクリアにして（Ｓ１７）、動作を終了する。ユーザの操作がオフ操作以外である場合（Ｓ１６の「Ｎｏ」）、動作を終了する。 When the user's operation is a non-energy saving operation (S13), the energy saving apparatus 3 sets the energy state to a non-energy saving state (S14). On the other hand, when the user's operation is an energy saving operation (S13), the energy saving apparatus 3 cancels the non-energy saving state (S15). After executing step S14 or step S15, the process returns to step S11. If the user's operation is, for example, an off operation ("Yes" in S16), the number of execution times of energy saving control is cleared (S17), and the operation is terminated. When the user's operation is other than the off operation (“No” in S16), the operation is terminated.
　空調機器２の設定状態に変化がない場合（Ｓ１１の「Ｎｏ」）、省エネルギー装置３は、空調状態格納エリア３５１に格納されている最新の設定状態を参照する。エネルギー状態が非省エネルギー状態である場合（Ｓ１８の「Ｙｅｓ」）、現在時刻と、最新の設定状態に対応して安定状態格納エリア３５２に格納されている格納時刻との差分が、判定値格納エリア３５３に格納されている閾値を超えていると（Ｓ１９の「Ｙｅｓ」）、省エネルギー装置３は、省エネルギー制御の実行回数を１増やす（Ｓ２０）。その後、実行回数が制限回数未満である場合（Ｓ２１の「Ｙｅｓ」）、省エネルギー装置３は、例えば空調機器２の設定温度を２８度に設定するように省エネルギー制御を行う（Ｓ２２）。その後、省エネルギー装置３は、非省エネルギー状態を解除する（Ｓ２３）。一方、ステップＳ２１において、実行回数が制限回数以上である場合（Ｓ２１の「Ｎｏ」）、動作を終了する。なお、ステップＳ１８において、エネルギー状態が非省エネルギー状態ではない場合（Ｓ１８の「Ｎｏ」）、ステップＳ１９において、上記差分が閾値を超えていない場合（Ｓ１９の「Ｎｏ」）、ステップＳ１１に戻る。 When there is no change in the setting state of the air conditioner 2 (“No” in S11), the energy saving apparatus 3 refers to the latest setting state stored in the air conditioning state storage area 351. When the energy state is a non-energy saving state (“Yes” in S18), the difference between the current time and the storage time stored in the stable state storage area 352 corresponding to the latest set state is the determination value storage area. If the threshold stored in 353 is exceeded (“Yes” in S19), the energy saving apparatus 3 increases the number of executions of energy saving control by 1 (S20). Thereafter, when the number of executions is less than the limit number ("Yes" in S21), the energy saving apparatus 3 performs energy saving control so as to set the set temperature of the air conditioner 2 to 28 degrees, for example (S22). Thereafter, the energy saving apparatus 3 cancels the non-energy saving state (S23). On the other hand, if the number of executions is greater than or equal to the limit number in step S21 (“No” in S21), the operation is terminated. In step S18, if the energy state is not a non-energy saving state ("No" in S18), if the difference does not exceed the threshold value in step S19 ("No" in S19), the process returns to step S11.
　以上説明した本実施形態の省エネルギーシステム１では、省エネルギー制御の実行回数を一定回数以下に規制することによって、頻繁に省エネルギー制御が行われることへの反感を抑えることができる。 In the energy saving system 1 according to the present embodiment described above, by restricting the number of executions of the energy saving control to a predetermined number or less, it is possible to suppress a feeling of reluctance to frequently perform the energy saving control.
　なお、本実施形態の省エネルギー制御の実行回数を制限する機能を、実施形態１の省エネルギー装置３だけではなく、実施形態２，３の省エネルギー装置３に適用してもよい。 Note that the function of limiting the number of executions of the energy saving control of the present embodiment may be applied not only to the energy saving device 3 of the first embodiment but also to the energy saving device 3 of the second and third embodiments.

　本実施形態の省エネルギー装置３の処理装置３７は、図１１に示すように、省エネルギー制御を行ってからの経過時間が制限時間を超えたか否かを判断する第２の判断部３７４をさらに備えている。第２の判断部３７４で用いられる制限時間は予め決められた所定の時間であり、コントローラ側記憶部３５の制限時間格納エリア３５６に格納されている。 As shown in FIG. 11, the processing device 37 of the energy saving device 3 of the present embodiment further includes a second determination unit 374 that determines whether or not an elapsed time after performing the energy saving control has exceeded a time limit. Yes. The time limit used by the second determination unit 374 is a predetermined time determined in advance, and is stored in the time limit storage area 356 of the controller-side storage unit 35.
　本実施形態の制御部３７２は、空調機器２が安定動作になったと判断部３７１で判断された場合に、経過時間が制限時間を超えたと第２の判断部３７４で判断されると、省エネルギー制御を新たに行う。一方、空調機器２が安定動作になったと判断部３７１で判断された場合であっても、経過時間が制限時間を超えていないと第２の判断部３７４で判断されると、制御部３７２は、省エネルギー制御を行わない。なお、実施形態１の制御部３７２と同様の機能については説明を省略する。 When the determination unit 371 determines that the air conditioner 2 has performed a stable operation, the control unit 372 according to the present embodiment determines that the elapsed time has exceeded the time limit and the second determination unit 374 determines the energy saving control. Do a new. On the other hand, even if the determination unit 371 determines that the air conditioner 2 has become stable, if the second determination unit 374 determines that the elapsed time does not exceed the time limit, the control unit 372 Do not perform energy saving control. Note that description of functions similar to those of the control unit 372 of the first embodiment is omitted.
　次に、本実施形態に係る省エネルギーシステム１の動作について図１２を用いて説明する。省エネルギー装置３は、空調機器２から状態変化情報を受け取った場合（Ｓ３１の「Ｙｅｓ」）、状態変化情報を空調状態格納エリア３５１に格納し、空調状態格納エリア３５１に格納されている状態変化情報ごとに、状態変化情報を格納した格納時刻（現在時刻）を表わす時刻情報を安定状態格納エリア３５２に格納する（Ｓ３２）。必要に応じて、省エネルギー装置３は、状態変化情報を表示器５に出力し、表示器５は、状態変化情報の内容（空調機器２の設定状態）を表示する。 Next, the operation of the energy saving system 1 according to the present embodiment will be described with reference to FIG. When the energy saving device 3 receives the state change information from the air conditioner 2 (“Yes” in S31), the state change information is stored in the air conditioning state storage area 351, and the state change information stored in the air conditioning state storage area 351 is stored. Each time, the time information indicating the storage time (current time) at which the state change information is stored is stored in the stable state storage area 352 (S32). If necessary, the energy saving device 3 outputs state change information to the display 5, and the display 5 displays the contents of the state change information (setting state of the air conditioner 2).
　ユーザの操作が非省エネルギー操作である場合（Ｓ３３）、省エネルギー装置３は、エネルギー状態を非省エネルギー状態に設定する（Ｓ３４）。一方、ユーザの操作が省エネルギー操作である場合（Ｓ３３）、省エネルギー装置３は、非省エネルギー状態を解除する（Ｓ３５）。ステップＳ３４またはステップＳ３５の実行後、ステップＳ３１に戻る。なお、ユーザの操作が例えばオフ操作などである場合（Ｓ３３）、動作を終了する。 When the user's operation is a non-energy saving operation (S33), the energy saving device 3 sets the energy state to a non-energy saving state (S34). On the other hand, when the user's operation is an energy saving operation (S33), the energy saving apparatus 3 cancels the non-energy saving state (S35). After executing Step S34 or Step S35, the process returns to Step S31. If the user operation is, for example, an off operation (S33), the operation is terminated.
　空調機器２の設定状態に変化がない場合（Ｓ３１の「Ｎｏ」）、省エネルギー装置３は、空調状態格納エリア３５１に格納されている最新の設定状態を参照する。エネルギー状態が非省エネルギー状態である場合（Ｓ３６の「Ｙｅｓ」）、現在時刻と、最新の設定状態に対応して安定状態格納エリア３５２に格納されている格納時刻との差分が、判定値格納エリア３５３に格納されている閾値を超えていると（Ｓ３７）、省エネルギー装置３は、現在時刻と省エネルギー実行時刻との差分が制限時間より長い場合（Ｓ３８の「Ｙｅｓ」）、現在時刻を省エネルギー実行時刻として格納し（Ｓ３９）、例えば空調機器２の設定温度を２８度に設定するように、空調機器２の負荷を緩和する方向へ省エネルギー制御を行う（Ｓ４０）。その後、省エネルギー装置３は、非省エネルギー状態を解除する（Ｓ４１）。一方、ステップＳ３８において、現在時刻と省エネルギー実行時刻との差分が制限時間以下である場合（Ｓ３８の「Ｎｏ」）、動作を終了する。なお、ステップＳ３６において、エネルギー状態が非省エネルギー状態ではない場合（Ｓ３６の「Ｎｏ」）、ステップＳ３７において、上記差分が閾値を超えていない場合（Ｓ３７の「Ｎｏ」）、ステップＳ３１に戻る。 When there is no change in the setting state of the air conditioner 2 (“No” in S31), the energy saving apparatus 3 refers to the latest setting state stored in the air conditioning state storage area 351. When the energy state is the non-energy saving state (“Yes” in S36), the difference between the current time and the storage time stored in the stable state storage area 352 corresponding to the latest set state is the determination value storage area. If the threshold value stored in 353 is exceeded (S37), the energy saving apparatus 3 sets the current time to the energy saving execution time when the difference between the current time and the energy saving execution time is longer than the time limit ("Yes" in S38). (S39), for example, energy saving control is performed in a direction to reduce the load on the air conditioner 2 so that the set temperature of the air conditioner 2 is set to 28 degrees (S40). Thereafter, the energy saving device 3 cancels the non-energy saving state (S41). On the other hand, in step S38, when the difference between the current time and the energy saving execution time is equal to or shorter than the time limit (“No” in S38), the operation ends. In step S36, when the energy state is not a non-energy saving state (“No” in S36), in step S37, if the difference does not exceed the threshold value (“No” in S37), the process returns to step S31.
　以上説明した本実施形態の省エネルギーシステム１では、ユーザ操作後の省エネルギー制御の実行を所定時間空けることで、頻繁に省エネルギー制御が行われることへの反感を抑えることができる。 In the energy saving system 1 of the present embodiment described above, it is possible to suppress a sense of discomfort to frequently perform energy saving control by leaving the execution of energy saving control after a user operation for a predetermined time.
　なお、本実施形態の省エネルギー制御を行う時間間隔を制限する機能を、実施形態１の省エネルギー装置３だけではなく、実施形態２，３の省エネルギー装置に適用してもよい。 In addition, you may apply the function which restrict | limits the time interval which performs energy saving control of this embodiment not only to the energy saving apparatus 3 of Embodiment 1 but to the energy saving apparatus of Embodiment 2,3.
