FIG. 1 shows a configuration of an air conditioning control system of the present embodiment. The air conditioning control system includes an air conditioning control device 1, an air conditioning device 2, a power measurement unit 3, and a manual operation unit 4. In this system, the set temperature of the air conditioner 2 for a predetermined space area to be air-conditioned by the air conditioner 2 is set to a temperature within a predetermined temperature range (hereinafter referred to as “target temperature”). It is configured to control the air conditioner 2 so that the temperature (hereinafter referred to as “air-conditioned temperature”) matches the target temperature. In the present embodiment, the air conditioning control device 1 is configured to set the set temperature of the air conditioning equipment 2 to the target temperature, and the air conditioning equipment 2 is configured to drive to match the air-conditioned temperature with the target temperature. . Note that examples of the space area in which the air-conditioning environment is controlled by the air conditioner 2 include each dwelling unit of a housing complex, a single-family house, each room of an office, a factory, and the like, but are limited to the form of these space areas. It is not something.
　空調制御装置１は、空調機器２および電力計測部３との間で通信可能に構成される通信部１０を備える。通信部１０は、有線通信部または無線通信部のいずれでもよい。また、空調制御装置１は、制御部１１と、信号入力部１２と、学習記憶部１３と、タイミング決定部１４とを備える。 The air conditioning control device 1 includes a communication unit 10 configured to be able to communicate with the air conditioning device 2 and the power measurement unit 3. The communication unit 10 may be either a wired communication unit or a wireless communication unit. In addition, the air conditioning control device 1 includes a control unit 11, a signal input unit 12, a learning storage unit 13, and a timing determination unit 14.
　制御部１１は、例えば、プログラムやデータを記憶するための記憶装置およびプログラムを実行するためのマイクロコンピュータなどを含み、目標温度を示す目標温度データを含む温度制御信号を、通信部１０を介して空調機器２へ送信するように構成される。空調機器２は、空調制御装置１から送信された温度制御信号に基づいて当該空調機器２の設定温度を目標温度に設定する。つまり、空調機器２は、その設定温度を、温度制御信号から得られる目標温度に設定し、空間領域内の温度、即ち被空調温度がその目標温度に一致するように、空調制御を行うように構成される。すなわち、空調制御装置１の制御部１１が、空調機器２の設定温度を目標温度に自動設定している。 The control unit 11 includes, for example, a storage device for storing a program and data, a microcomputer for executing the program, and the like, and sends a temperature control signal including target temperature data indicating the target temperature via the communication unit 10. It is configured to transmit to the air conditioner 2. The air conditioning device 2 sets the set temperature of the air conditioning device 2 to the target temperature based on the temperature control signal transmitted from the air conditioning control device 1. That is, the air conditioner 2 sets the set temperature to the target temperature obtained from the temperature control signal, and performs the air conditioning control so that the temperature in the space area, that is, the air-conditioned temperature matches the target temperature. Composed. That is, the control unit 11 of the air conditioning control device 1 automatically sets the set temperature of the air conditioning equipment 2 to the target temperature.
　制御部１１は、空調機器２の設定温度を、予め決められた目標温度（以下「第１目標温度」という）に設定するための少なくとも１つの第１制御（モード）を有し、第１制御下で空調機器２の設定温度をその第１目標温度に設定するように構成される。本実施形態では、第１制御は、ユーザの快適性を確保するための快適制御であり、制御部１１は、複数（例えば２つ）の第１制御（モード）を有し、通常、快適制御を実行するように構成される。即ち、制御部１１は、予め決められた空調制御パターン（快適制御）にしたがって、空調機器２の設定温度を目標温度（第１目標温度）に設定する。例えば、冬季における空調機器２の暖房運転時、制御部１１は、ユーザの快適性を確保するために、空調機器２の設定温度を、一般に省エネルギー温度と称される「２０℃」より高い目標温度（第１目標温度）に設定する。また、夏季における空調機器２の冷房運転時、制御部１１は、ユーザの快適性を確保するために、空調機器２の設定温度を、一般に省エネルギー温度と称される「２８℃」より低い目標温度（第１目標温度）に設定する。 The control unit 11 has at least one first control (mode) for setting the set temperature of the air conditioner 2 to a predetermined target temperature (hereinafter referred to as “first target temperature”), and the first control Below, it is comprised so that the preset temperature of the air conditioning equipment 2 may be set to the 1st target temperature. In the present embodiment, the first control is a comfort control for ensuring the user's comfort, and the control unit 11 has a plurality of (for example, two) first controls (modes), and usually the comfort control. Configured to perform. That is, the control unit 11 sets the set temperature of the air conditioner 2 to the target temperature (first target temperature) according to a predetermined air conditioning control pattern (comfort control). For example, during the heating operation of the air conditioner 2 in winter, the control unit 11 sets the set temperature of the air conditioner 2 to a target temperature higher than “20 ° C.”, which is generally referred to as an energy saving temperature, in order to ensure user comfort. Set to (first target temperature). Further, during the cooling operation of the air conditioner 2 in summer, the control unit 11 sets the set temperature of the air conditioner 2 to a target temperature lower than “28 ° C.”, which is generally referred to as an energy saving temperature, in order to ensure user comfort. Set to (first target temperature).
　空調機器２は、上記のようにユーザの快適性を確保した目標温度が設定された場合、結果として、消費電力が大きくなる。以降、このユーザの快適性を確保した空調制御（第１制御）を通常制御とも称す。 When the target temperature that ensures the user's comfort is set as described above, the air conditioner 2 results in increased power consumption. Hereinafter, the air conditioning control (first control) that ensures the comfort of the user is also referred to as normal control.
　また、この目標温度設定は、制御部１１による自動制御だけでなく、手動操作部４を用いたユーザによる手動設定も可能である。即ち、空調機器２は、ユーザによって手動操作部４を通じて設定温度を上記温度範囲内の温度に設定ないしは変更することができるように構成される。例えば、手動操作部４は、空調機器２との間で通信可能に構成されており、ユーザ操作によって設定ないしは変更された目標温度を示す目標温度データを含む温度制御信号を、空調機器２へ送信するように構成される。空調機器２は、手動操作部４から送信された温度制御信号に基づいて設定温度を目標温度に設定する。つまり、空調機器２は、その設定温度を、温度制御信号から得られる目標温度に設定し、空間領域内の温度（被空調温度）がその目標温度に一致するように、空調制御を行うように構成される。この場合、手動操作部４を通じて、空調機器２の設定温度が目標温度に手動設定される。また、空調機器２は、手動操作部４を通じて設定された目標温度（例えばユーザによって設定ないしは変更された目標温度を示す目標温度データを含む温度制御信号）を空調制御装置１に送信するように構成される。 Further, the target temperature setting can be not only automatic control by the control unit 11 but also manual setting by the user using the manual operation unit 4. That is, the air conditioner 2 is configured such that the user can set or change the set temperature to a temperature within the above temperature range through the manual operation unit 4. For example, the manual operation unit 4 is configured to be communicable with the air conditioner 2, and transmits a temperature control signal including target temperature data indicating the target temperature set or changed by a user operation to the air conditioner 2. Configured to do. The air conditioner 2 sets the set temperature to the target temperature based on the temperature control signal transmitted from the manual operation unit 4. That is, the air conditioner 2 sets the set temperature to the target temperature obtained from the temperature control signal, and performs air conditioning control so that the temperature in the space region (temperature to be air conditioned) matches the target temperature. Composed. In this case, the set temperature of the air conditioner 2 is manually set to the target temperature through the manual operation unit 4. In addition, the air conditioner 2 is configured to transmit a target temperature set through the manual operation unit 4 (for example, a temperature control signal including target temperature data indicating target temperature set or changed by the user) to the air conditioning control device 1. Is done.
　また、制御部１１は、空調機器２の設定温度を、予め決められた目標温度（以下「第２目標温度」という）に設定するための少なくとも１つの第２制御（モード）を有し、第２制御下で空調機器２の設定温度をその第２目標温度に設定するように構成され、ここで、第２制御による空調機器２の消費エネルギーは、第１制御による空調機器２の消費エネルギーよりも低減される。例えば、第１制御プログラムおよび第２制御プログラムは、第２制御による空調機器２の消費エネルギーが第１制御による空調機器２の消費エネルギーよりも低減されるように作成される。本実施形態では、制御部１１は、複数（例えば２つ）の第２制御（モード）を有し、決まった時刻（制御開始時刻）において、空調機器２の消費電力（消費エネルギー）が低減する方向に、空調機器２の設定温度を変更する。空調機器２の暖房運転時には、制御部１１は、例えば、省エネルギー温度「２０℃」より低い温度（例えば「１８℃」）を示す目標温度データを含む温度制御信号を空調機器２に送信する。空調機器２の冷房運転時には、制御部１１は、例えば、省エネルギー温度「２８℃」より高い温度（例えば「３０℃」）を示す目標温度データを含む温度制御信号を空調機器２に送信する。以降、空調機器２の設定温度を強制的に省エネルギー方向に変更する空調制御（第２制御）を、省エネルギー制御とも称す。 The control unit 11 has at least one second control (mode) for setting the set temperature of the air conditioner 2 to a predetermined target temperature (hereinafter referred to as “second target temperature”). It is configured to set the set temperature of the air conditioner 2 to the second target temperature under the second control, where the energy consumption of the air conditioner 2 by the second control is more than the energy consumption of the air conditioner 2 by the first control. Is also reduced. For example, the first control program and the second control program are created so that the energy consumption of the air conditioner 2 by the second control is reduced than the energy consumption of the air conditioner 2 by the first control. In the present embodiment, the control unit 11 has a plurality of (for example, two) second controls (modes), and power consumption (energy consumption) of the air conditioner 2 is reduced at a fixed time (control start time). The set temperature of the air conditioner 2 is changed in the direction. During the heating operation of the air conditioner 2, the controller 11 transmits a temperature control signal including target temperature data indicating a temperature lower than the energy saving temperature “20 ° C.” (for example, “18 ° C.”) to the air conditioner 2. During the cooling operation of the air conditioner 2, the control unit 11 transmits to the air conditioner 2 a temperature control signal including target temperature data indicating a temperature (for example, “30 ° C.”) higher than the energy saving temperature “28 ° C.”, for example. Hereinafter, the air conditioning control (second control) for forcibly changing the set temperature of the air conditioner 2 in the energy saving direction is also referred to as energy saving control.
　このように、制御部１１は、空調機器２の設定温度を強制的に目標温度（省エネルギー方向）に変更することによって、空調機器２の消費電力を低減させる省エネルギー制御を、予め決められた制御開始時刻に実行する。 In this way, the control unit 11 forcibly changes the set temperature of the air conditioner 2 to the target temperature (energy saving direction), thereby starting energy saving control for reducing the power consumption of the air conditioner 2 in a predetermined control start. Run at time.
　図２は、空調機器２の暖房運転時における省エネルギー制御（第２制御）を示す。制御開始時刻ｔ１以前、制御部１１は、空調機器２の設定温度を省エネルギー温度「２０℃」より高い目標温度Ｔｍ１に設定して通常制御（第１制御）を行い、ユーザの快適性を確保している。そして、制御部１１は、予め決められた制御開始時刻ｔ１に、空調機器２の設定温度を省エネルギー温度「２０℃」より低い目標温度Ｔｍ２に変更して省エネルギー制御（第２制御）を行い、空調機器２の消費電力を低減させる。 FIG. 2 shows energy saving control (second control) during the heating operation of the air conditioner 2. Prior to the control start time t1, the control unit 11 performs normal control (first control) by setting the set temperature of the air conditioner 2 to a target temperature Tm1 higher than the energy saving temperature “20 ° C.” to ensure user comfort. ing. Then, the control unit 11 performs the energy saving control (second control) by changing the set temperature of the air conditioner 2 to the target temperature Tm2 lower than the energy saving temperature “20 ° C.” at a predetermined control start time t1. The power consumption of the device 2 is reduced.
　そして、制御開始時刻ｔ１以降、ユーザが省エネルギー制御に対して不快であると感じると、ユーザは、手動操作部４を通じて空調機器２の設定温度を目標温度Ｔｍ２から目標温度（指定温度）Ｔｍ３に引き上げる（ユーザ操作時刻ｔ２）。以降、制御開始時刻ｔ１からユーザ操作時刻ｔ２までの期間を省エネルギー制御期間（第２制御期間）Ｗ１と称し、ユーザ操作時刻ｔ２以降の期間をユーザ操作期間Ｗ２と称す。 When the user feels uncomfortable with respect to the energy saving control after the control start time t1, the user raises the set temperature of the air conditioner 2 from the target temperature Tm2 to the target temperature (designated temperature) Tm3 through the manual operation unit 4. (User operation time t2). Hereinafter, a period from the control start time t1 to the user operation time t2 is referred to as an energy saving control period (second control period) W1, and a period after the user operation time t2 is referred to as a user operation period W2.
　ユーザの手動操作によって引き上げられた目標温度Ｔｍ３は、省エネルギー制御時の目標温度Ｔｍ２より高いが、一般に、制御部１１による通常制御時の目標温度Ｔｍ１より低くなることが多い。なお、目標温度Ｔｍ３の引き上げ幅Ｔａは、ユーザの空調環境に対する好みによって異なる。 The target temperature Tm3 raised by the user's manual operation is higher than the target temperature Tm2 at the time of energy saving control, but is generally often lower than the target temperature Tm1 at the time of normal control by the control unit 11. In addition, raising range Ta of target temperature Tm3 changes with user's liking with respect to an air-conditioning environment.
　このような空調制御を行うことによって、省エネルギー制御期間Ｗ１およびユーザ操作期間Ｗ２における目標温度Ｔｍ２，Ｔｍ３は、制御部１１の通常制御時の目標温度Ｔｍ１より低くなる。したがって、制御開始時刻ｔ１以降における空調機器２の消費電力は、通常制御を行う場合に比べて低減する。 By performing such air conditioning control, the target temperatures Tm2 and Tm3 in the energy saving control period W1 and the user operation period W2 become lower than the target temperature Tm1 during the normal control of the control unit 11. Therefore, the power consumption of the air conditioner 2 after the control start time t1 is reduced compared to the case where normal control is performed.
　しかしながら、目標温度を変更して省エネルギー制御を行ったとしても、この省エネルギー制御によって快適性が損なわれたユーザは、省エネルギー制御に対して不快感を抱く場合がある。一般に、この省エネルギー制御に対するユーザの不快感は、ユーザの空調環境に対する好み、季節、天候、気温、湿度、空間領域内の人数等によって変動する。 However, even if energy saving control is performed by changing the target temperature, a user whose comfort is impaired by the energy saving control may be uncomfortable with the energy saving control. In general, the user's discomfort with respect to this energy saving control varies depending on the user's preference for the air-conditioning environment, season, weather, temperature, humidity, the number of people in the space region, and the like.
　例えば、冬季の昼間は、夜間に比べて暖かく、空調機器２の省エネルギー制御（第２制御）に対する不快感が小さい。また、冬季において、部屋内の人数が多い時間帯も、空調機器２の省エネルギー制御に対する不快感が小さい。また、夏季の夜間は、昼間に比べて涼しく、空調機器２の省エネルギー制御に対する不快感が小さい。また、夏季において、部屋内の人数が少ない時間帯も、空調機器２の省エネルギー制御に対する不快感が小さい。また、この不快感の感じ方には、ユーザによって個人差がある。 For example, winter daytime is warmer than nighttime, and the discomfort with respect to the energy saving control (second control) of the air conditioner 2 is small. Further, in winter, even during times when the number of people in the room is large, the discomfort with respect to the energy saving control of the air conditioner 2 is small. Moreover, it is cooler in the summer at night than in the daytime, and the discomfort for the energy saving control of the air conditioner 2 is small. Further, in the summer, even when the number of people in the room is small, the discomfort with respect to the energy saving control of the air conditioner 2 is small. Further, there are individual differences in how to feel this discomfort depending on the user.
　このように、省エネルギー制御の制御開始時刻ｔ１の時刻設定によって、省エネルギー制御に対してユーザが感じる不快感が変動する。そして、省エネルギー制御に対するユーザの不快感が大きいほど、ユーザ操作時刻ｔ２が早くなるので、省エネルギー制御期間Ｗ１の時間長さが短くなり、さらには目標温度Ｔｍ３の引き上げ幅Ｔａが大きくなる。つまり、ユーザの不快感が大きい場合、省エネルギー制御による消費電力の低減量が小さく、省エネルギー制御による省エネルギー効果は小さくなる。 As described above, the discomfort felt by the user with respect to the energy saving control varies depending on the time setting of the control start time t1 of the energy saving control. As the user's discomfort with respect to the energy saving control is larger, the user operation time t2 is earlier, so the time length of the energy saving control period W1 is shortened, and further, the raising width Ta of the target temperature Tm3 is increased. That is, when the user's discomfort is large, the amount of power consumption reduction by energy saving control is small, and the energy saving effect by energy saving control is small.
　そこで、空調制御装置１のタイミング決定部１４は、図３のフローチャートに示すように、省エネルギー制御（第２制御）によるユーザの不快感が小さく、省エネルギー効果が大きく（消費電力の低減量が大きく）なる制御開始時刻ｔ１を設定する（Ｓ１）。以降、制御部１１は、タイミング決定部１４によって設定された制御開始時刻ｔ１に、空調機器２の設定温度を目標温度Ｔｍ２に変更するための省エネルギー制御を行う（Ｓ２）。そして、このタイミング決定部１４による制御開始時刻ｔ１の設定処理を定期的に実行することにより、季節、天候、気温、湿度、空間領域内の人数等に応じて、ユーザの不快感が小さく、省エネルギー効果が大きくなる制御開始時刻ｔ１に随時更新することができる。 Therefore, as shown in the flowchart of FIG. 3, the timing determination unit 14 of the air conditioning control device 1 has less user discomfort due to energy saving control (second control), and has a large energy saving effect (a large reduction in power consumption). A control start time t1 is set (S1). Thereafter, the control unit 11 performs energy saving control for changing the set temperature of the air conditioner 2 to the target temperature Tm2 at the control start time t1 set by the timing determination unit 14 (S2). Then, by periodically executing the setting process of the control start time t1 by the timing determination unit 14, the user's discomfort is small and energy saving according to the season, weather, temperature, humidity, the number of people in the space area, and the like. It can be updated at any time at the control start time t1 when the effect becomes large.
　以下、ステップＳ１で実行される制御開始時刻ｔ１の決定処理について、図４のフローチャートを用いて説明する。 Hereinafter, the determination process of the control start time t1 executed in step S1 will be described with reference to the flowchart of FIG.
　まず、制御部１１は、所定時刻において、空調機器２の設定温度を通常制御時の目標温度Ｔｍ１に維持した状態から目標温度Ｔｍ２に変更するための省エネルギー制御の温度制御信号を送信する（Ｓ１１）。以降、制御開始時刻ｔ１の決定処理を行うために制御部１１が送信する省エネルギー制御の温度制御信号を、第１の学習信号と称す。 First, at a predetermined time, the control unit 11 transmits a temperature control signal for energy saving control for changing the set temperature of the air conditioner 2 from the state maintained at the target temperature Tm1 during normal control to the target temperature Tm2 (S11). . Hereinafter, the temperature control signal for energy saving control transmitted by the control unit 11 to perform the determination process of the control start time t1 is referred to as a first learning signal.
　そして、この第１の学習信号による制御開始時刻ｔ１から省エネルギー制御が行われた後、ユーザが省エネルギー制御に対して不快であると感じると、ユーザは、手動操作部４を通じて設定温度を目標温度Ｔｍ２から目標温度Ｔｍ３に引き上げる（ユーザ操作時刻ｔ２）。手動操作部４を通じて手動設定された目標温度Ｔｍ３のデータは、ユーザ操作時刻ｔ２のデータとともに、空調機器２から空調制御装置１の信号入力部１２へ送信される（Ｓ１２）。学習記憶部１３は、ユーザ操作時刻ｔ２および目標温度Ｔｍ３の各データを、制御開始時刻ｔ１のデータに対応付けて格納する（Ｓ１３）。 Then, after the energy saving control is performed from the control start time t1 based on the first learning signal, when the user feels uncomfortable with respect to the energy saving control, the user sets the set temperature to the target temperature Tm2 through the manual operation unit 4. To the target temperature Tm3 (user operation time t2). The data of the target temperature Tm3 manually set through the manual operation unit 4 is transmitted from the air conditioner 2 to the signal input unit 12 of the air conditioning control device 1 together with the data of the user operation time t2 (S12). The learning storage unit 13 stores each data of the user operation time t2 and the target temperature Tm3 in association with the data of the control start time t1 (S13).
　そして、タイミング決定部１４は、学習記憶部１３に格納している各データ（制御開始時刻ｔ１、ユーザ操作時刻ｔ２、目標温度Ｔｍ２，Ｔｍ３）に基づいて、省エネルギー制御期間Ｗ１の時間長さ、目標温度Ｔｍ３の引き上げ幅Ｔａを導出できる。したがって、タイミング決定部１４は、第１の学習信号によって実行された省エネルギー制御による省エネルギー効果を、省エネルギー制御期間Ｗ１の時間長さ、目標温度Ｔｍ３の引き上げ幅Ｔａに基づいて導出できる。この場合、省エネルギー制御期間Ｗ１の時間長さが長く、目標温度Ｔｍ３の引き上げ幅Ｔａが小さいほど、省エネルギー効果が大きくなる。 And the timing determination part 14 is based on each data (Control start time t1, User operation time t2, Target temperature Tm2, Tm3) stored in the learning memory | storage part 13, The time length of the energy saving control period W1, target The raising width Ta at the temperature Tm3 can be derived. Therefore, the timing determination unit 14 can derive the energy saving effect by the energy saving control executed by the first learning signal based on the time length of the energy saving control period W1 and the raising width Ta of the target temperature Tm3. In this case, as the time length of the energy saving control period W1 is longer and the raising width Ta of the target temperature Tm3 is smaller, the energy saving effect becomes larger.
　例えば、省エネルギー制御期間Ｗ１での省エネルギー効果は、Ｗ１×（Ｔｍ１－Ｔｍ２）で求めることができる。ユーザ操作期間Ｗ２での省エネルギー効果は、｛Ｗ２×（Ｔｍ１－Ｔｍ２）｝－｛Ｗ２×（Ｔｍ３－Ｔｍ２）｝＝｛Ｗ２×（Ｔｍ１－Ｔｍ２）｝－｛Ｗ２×Ｔａ｝で、求めることができる。したがって、第１の学習信号によって実行された省エネルギー制御による省エネルギー効果は、｛（Ｗ１＋Ｗ２）×（Ｔｍ１－Ｔｍ２）｝－｛Ｗ２×Ｔａ｝で求めることができる。なお、この第１の学習信号によって実行された省エネルギー制御による省エネルギー効果は、｛Ｗ１×（Ｔｍ１－Ｔｍ２）｝＋｛Ｗ２×（Ｔｍ１－Ｔｍ３）｝と展開することもできる。 For example, the energy saving effect in the energy saving control period W1 can be obtained by W1 × (Tm1−Tm2). The energy saving effect in the user operation period W2 can be obtained by {W2 × (Tm1−Tm2)} − {W2 × (Tm3−Tm2)} = {W2 × (Tm1−Tm2)} − {W2 × Ta}. it can. Therefore, the energy saving effect by the energy saving control executed by the first learning signal can be obtained by {(W1 + W2) × (Tm1−Tm2)} − {W2 × Ta}. The energy saving effect by the energy saving control executed by the first learning signal can also be expanded as {W1 × (Tm1−Tm2)} + {W2 × (Tm1−Tm3)}.
　タイミング決定部１４は、複数の開始時刻候補を生成し、その複数の開始時刻候補から予め設定された閾値よりも小さい省エネルギー効果をもたらす開始時刻候補を除外し、少なくとも１つの開始時刻候補が残れば、残った開始時刻候補から制御開始時刻を決定するように構成される。例えば、複数の開始時刻候補は、時間軸に沿って間隔を置いて配置される。本実施形態では、タイミング決定部１４は、上記第１の学習信号による省エネルギー制御を、上記複数の開始時刻候補に対応する回数行うように構成される。各省エネルギー制御は、他と異なる制御開始時刻ｔ１に実行され、各時刻に実行した省エネルギー制御による省エネルギー効果が導出される。そして、タイミング決定部１４は、予め設定された閾値より小さい省エネルギー効果をもたらす制御開始時刻ｔ１を、拒絶制御開始時刻に設定することにより複数の開始時刻候補から除外する。さらに、タイミング決定部１４は、図５に示すように、制御開始時刻ｔ１から予め設定された判断期間Ｗ１１が経過するまでに引き上げられた目標温度Ｔｍ３が、通常制御時の目標温度Ｔｍ１より高い場合、この制御開始時刻ｔ１も拒絶制御開始時刻に設定することにより複数の開始時刻候補から除外する。そして、以降の省エネルギー制御では、拒絶制御開始時刻に設定された制御開始時刻ｔ１を用いることを禁止した上で、省エネルギー効果が予め設定された閾値以上である制御開始時刻ｔ１のみ（即ち残った開始時刻候補）を、以降の制御開始時刻として用いる（Ｓ１４）。すなわち、制御部１１は、拒絶制御開始時刻では省エネルギー制御の開始を禁止され、大きな省エネルギー効果（詳しくは予め設定された閾値以上の省エネルギー効果）をもたらす制御開始時刻ｔ１のみを省エネルギー制御に用いる。 The timing determination unit 14 generates a plurality of start time candidates, excludes start time candidates that bring about an energy saving effect smaller than a preset threshold from the plurality of start time candidates, and if at least one start time candidate remains. The control start time is determined from the remaining start time candidates. For example, the plurality of start time candidates are arranged at intervals along the time axis. In the present embodiment, the timing determination unit 14 is configured to perform the energy saving control by the first learning signal a number of times corresponding to the plurality of start time candidates. Each energy saving control is executed at a control start time t1 different from the others, and an energy saving effect is derived by the energy saving control executed at each time. And the timing determination part 14 is excluded from a some start time candidate by setting the control start time t1 which brings about the energy saving effect smaller than the preset threshold value to rejection control start time. Further, as shown in FIG. 5, the timing determination unit 14 determines that the target temperature Tm3 that has been raised from the control start time t1 until the predetermined determination period W11 elapses is higher than the target temperature Tm1 during normal control. The control start time t1 is also excluded from a plurality of start time candidates by setting the rejection control start time. In the subsequent energy saving control, it is prohibited to use the control start time t1 set as the rejection control start time, and only the control start time t1 in which the energy saving effect is equal to or greater than a preset threshold (that is, the remaining start). Time candidate) is used as the subsequent control start time (S14). That is, the control unit 11 is prohibited from starting the energy saving control at the rejection control start time, and uses only the control start time t1 that provides a large energy saving effect (specifically, an energy saving effect equal to or greater than a preset threshold) for the energy saving control.
　このようにして決定された省エネルギー制御の制御開始時刻ｔ１は、省エネルギー制御を開始した後における空調機器２の消費電力に基づいて決定されており、ユーザの不快感が小さく、省エネルギー効果が大きいなる効果をもたらす時刻になる。したがって、本空調制御システムでは、快適性と省エネルギー効果とを両立させることができる。また、省エネルギー効果が小さい時刻は、拒絶制御開始時刻に設定し、制御開始時刻ｔ１として用いないので、不要な省エネルギー制御を抑制でき、ユーザの不満を抑えることができる。 The control start time t1 of the energy saving control determined in this way is determined based on the power consumption of the air conditioner 2 after starting the energy saving control, and the effect that the user's discomfort is small and the energy saving effect is large. It will be time to bring Therefore, this air conditioning control system can achieve both comfort and energy saving effect. In addition, since the time when the energy saving effect is small is set as the rejection control start time and is not used as the control start time t1, unnecessary energy saving control can be suppressed and user dissatisfaction can be suppressed.
　さらに、上記のように決定した制御開始時刻ｔ１を、省エネルギー効果がより高い時刻に変更することができる。以下、制御開始時刻ｔ１の変更処理について、図６、図７Ａ～７Ｃを用いて説明する。 Furthermore, the control start time t1 determined as described above can be changed to a time when the energy saving effect is higher. Hereinafter, the changing process of the control start time t1 will be described with reference to FIGS. 6 and 7A to 7C.
　まず、制御開始時刻ｔ１に設定温度を第２目標温度に変更して省エネルギー制御（第２制御）を行ったとしても、季節、天候、気温、湿度、空間領域内の人数等によっては、省エネルギー効果が相対的に小さい場合がある。例えば、昼間および夜間に設定温度を同一の目標温度に設定したとしても、冬季の昼間は、夜間に比べて暖かく、空調機器２の暖房に要する消費電力も夜間に比べて少ない状況にあり、冬季の昼間に空調機器２の設定温度を下げたとしても、省エネルギー効果は小さい。また、冬季において、部屋内の人数が多い時間帯は、部屋内の人数が少ない時間帯に比べて、空調機器２の暖房に要する消費電力が少ない状況にあり、部屋内の人数が多い時間帯に空調機器２の目標温度を下げたとしても、省エネルギー効果は小さい。 First, even if the set temperature is changed to the second target temperature at the control start time t1 and energy saving control (second control) is performed, the energy saving effect depends on the season, weather, temperature, humidity, number of people in the space region, and the like. May be relatively small. For example, even if the set temperature is set to the same target temperature during the daytime and at night, the wintertime is warmer than the nighttime and the power consumption required for heating the air conditioner 2 is less than that at night. Even if the set temperature of the air conditioner 2 is lowered during the daytime, the energy saving effect is small. In winter, when the number of people in the room is large, the power consumption required for heating the air conditioner 2 is less than when the number of people in the room is small, and the number of people in the room is large. Even if the target temperature of the air conditioner 2 is lowered, the energy saving effect is small.
　そこで、タイミング決定部１４は、上記のように第１の学習信号を用いて決定した制御開始時刻ｔ１を含む所定期間Ｗｓ内に複数（図７Ａ～７Ｃでは３つ）の制御開始時刻ｔ１１，ｔ１２，ｔ１３を設定する。制御部１１は、制御開始時刻ｔ１１，ｔ１２，ｔ１３のそれぞれより以前に設定温度を通常制御時の目標温度Ｔｍ１に維持しておく。そして、制御部１１は、制御開始時刻ｔ１１，ｔ１２，ｔ１３のそれぞれで、目標温度Ｔｍ２のデータを含む省エネルギー制御の温度制御信号を空調機器２に送信する（Ｓ２１）。以降、制御開始時刻ｔ１の変更処理のために、所定期間Ｗｓ内で制御部１１が送信する省エネルギー制御の温度制御信号を、第２の学習信号と称す。 Therefore, the timing determination unit 14 controls a plurality of (three in FIGS. 7A to 7C) control start times t11 and t12 within a predetermined period Ws including the control start time t1 determined using the first learning signal as described above. , T13. The control unit 11 maintains the set temperature at the target temperature Tm1 during normal control before each of the control start times t11, t12, and t13. And the control part 11 transmits the temperature control signal of the energy saving control containing the data of target temperature Tm2 to the air-conditioning equipment 2 at each control start time t11, t12, t13 (S21). Hereinafter, the temperature control signal for energy saving control transmitted by the control unit 11 within the predetermined period Ws for the change process of the control start time t1 is referred to as a second learning signal.
　本システムは、空調機器２の消費電力（消費エネルギー）を測定するように構成される電力計測部３を設けており、電力計測部３が測定した空調機器２の消費電力データは、空調制御装置１の信号入力部１２へ送信され、学習記憶部１３に格納される。タイミング決定部１４は、学習記憶部１３から、空調機器２の消費電力データを取得することができる。 This system is provided with a power measuring unit 3 configured to measure power consumption (energy consumption) of the air conditioner 2. The power consumption data of the air conditioner 2 measured by the power measuring unit 3 is stored in the air conditioning control device. 1 to the signal input unit 12 and stored in the learning storage unit 13. The timing determination unit 14 can acquire power consumption data of the air conditioner 2 from the learning storage unit 13.
　そして、タイミング決定部１４は、制御開始時刻ｔ１１，ｔ１２，ｔ１３より以前において、空調機器２の消費電力データを電力計測部３から取得している。さらに、タイミング決定部１４は、制御開始時刻ｔ１１，ｔ１２，ｔ１３それぞれの直後においても、空調機器２の消費電力データを電力計測部３から取得する。そして、タイミング決定部１４は、制御開始時刻ｔ１１，ｔ１２，ｔ１３のそれぞれにおいて、制御開始時刻後における消費電力の低減量を算出する（Ｓ２２）。すなわち、設定温度が目標温度Ｔｍ１から目標温度Ｔｍ２に変更される直前での消費電力（図７Ａ～７Ｃ中のＰ１ａ，Ｐ２ａ，Ｐ３ａ）と、設定温度が目標温度Ｔｍ１から目標温度Ｔｍ２に変更された直後での消費電力（図７Ａ～７Ｃ中のＰ１ｂ，Ｐ２ｂ，Ｐ３ｂ）との差を算出する。 And the timing determination part 14 has acquired the power consumption data of the air conditioner 2 from the electric power measurement part 3 before control start time t11, t12, t13. Furthermore, the timing determination unit 14 acquires the power consumption data of the air conditioner 2 from the power measurement unit 3 immediately after each of the control start times t11, t12, and t13. And the timing determination part 14 calculates the reduction amount of the power consumption after control start time in each of control start time t11, t12, t13 (S22). That is, power consumption (P1a, P2a, P3a in FIGS. 7A to 7C) immediately before the set temperature is changed from the target temperature Tm1 to the target temperature Tm2, and the set temperature is changed from the target temperature Tm1 to the target temperature Tm2. The difference from the power consumption immediately after (P1b, P2b, P3b in FIGS. 7A to 7C) is calculated.
　次に、タイミング決定部１４は、制御開始時刻ｔ１１，ｔ１２，ｔ１３のうち、その前後における消費電力の低減量が最も大きい制御開始時刻を、所定期間Ｗｓ内の新たな制御開始時刻ｔ１に設定する（Ｓ２３）。 Next, the timing determination unit 14 sets the control start time with the largest reduction in power consumption before and after the control start times t11, t12, and t13 as a new control start time t1 within the predetermined period Ws. (S23).
　このようにして変更された制御開始時刻ｔ１は、所定期間Ｗｓ内で省エネルギー制御による最も大きい省エネルギー効果をもたらす時刻になる。また、制御開始時刻ｔ１１，ｔ１２，ｔ１３直後の消費電力データを用いるので、制御開始時刻ｔ１の変更処理に要する時間が短くなる。 The control start time t1 changed in this way is the time that brings the greatest energy saving effect by the energy saving control within the predetermined period Ws. Further, since the power consumption data immediately after the control start times t11, t12, and t13 is used, the time required for changing the control start time t1 is shortened.
　なお、空調機器２の冷房運転時における空調制御では、制御開始時刻ｔ１に目標温度を上げて省エネルギー制御を行い、空調機器２の消費電力を低減させることによって、上記同様の効果を得ることができる。 In the air conditioning control during the cooling operation of the air conditioner 2, the same effect as described above can be obtained by increasing the target temperature at the control start time t1 to perform energy saving control and reducing the power consumption of the air conditioner 2. .

The present embodiment is another form of the process of changing the control start time t1 using the second learning signal in the first embodiment, and will be described with reference to FIGS. 8 and 9A to 9C.
　まず、タイミング決定部１４は、第１の学習信号を用いて決定した制御開始時刻ｔ１を含む所定期間Ｗｓ内に複数（図９Ａ～９Ｃでは３つ）の制御開始時刻ｔ２１，ｔ２２，ｔ２３を設定する。制御部１１は、制御開始時刻ｔ２１，ｔ２２，ｔ２３のそれぞれより以前に設定温度を通常制御時の目標温度Ｔｍ１に維持しておく。そして、制御部１１は、制御開始時刻ｔ２１，ｔ２２，ｔ２３のそれぞれで、目標温度Ｔｍ２のデータを含む省エネルギー制御の温度制御信号を空調機器２に送信する（Ｓ３１）。以降、制御開始時刻ｔ１の変更処理のために、所定期間Ｗｓ内で制御部１１が送信する省エネルギー制御の温度制御信号を、第２の学習信号と称す。 First, the timing determination unit 14 sets a plurality (three in FIGS. 9A to 9C) of control start times t21, t22, and t23 within a predetermined period Ws including the control start time t1 determined using the first learning signal. To do. The control unit 11 maintains the set temperature at the target temperature Tm1 during normal control before each of the control start times t21, t22, and t23. And the control part 11 transmits the temperature control signal of the energy saving control containing the data of target temperature Tm2 to the air-conditioning equipment 2 at each control start time t21, t22, t23 (S31). Hereinafter, the temperature control signal for energy saving control transmitted by the control unit 11 within the predetermined period Ws for the change process of the control start time t1 is referred to as a second learning signal.
　本システムは、空調機器２の消費電力（消費エネルギー）を測定する電力計測部３を設けており、電力計測部３が測定した空調機器２の消費電力データは、空調制御装置１の信号入力部１２へ送信され、学習記憶部１３に格納される。タイミング決定部１４は、学習記憶部１３から、空調機器２の消費電力データを取得することができる。 This system includes a power measurement unit 3 that measures power consumption (energy consumption) of the air conditioner 2, and power consumption data of the air conditioner 2 measured by the power measurement unit 3 is used as a signal input unit of the air conditioning control device 1. 12 and stored in the learning storage unit 13. The timing determination unit 14 can acquire power consumption data of the air conditioner 2 from the learning storage unit 13.
　そして、タイミング決定部１４は、制御開始時刻ｔ２１，ｔ２２，ｔ２３より以前において、空調機器２の消費電力データを電力計測部３から取得している。さらに、タイミング決定部１４は、制御開始時刻ｔ２１，ｔ２２，ｔ２３後の各積算期間Ｗ２１，Ｗ２２，Ｗ２３においても、空調機器２の消費電力データを電力計測部３から取得する。そして、タイミング決定部１４は、各積算期間Ｗ２１，Ｗ２２，Ｗ２３において、制御開始時刻後における消費電力の低減量を積算する（Ｓ３２）。すなわち、設定温度が目標温度Ｔｍ１から目標温度Ｔｍ２に変更される直前での消費電力と、設定温度が目標温度Ｔｍ１から目標温度Ｔｍ２に変更された後の各積算期間Ｗ２１，Ｗ２２，Ｗ２３における消費電力との差を積算する（図９Ａ～９Ｃ中のハッチング領域Ｐ２１，Ｐ２２，Ｐ２３における消費電力）。なお、各積算期間Ｗ２１，Ｗ２２，Ｗ２３は、互いに同じ時間長さに設定する。 And the timing determination part 14 has acquired the power consumption data of the air conditioner 2 from the electric power measurement part 3 before control start time t21, t22, t23. Further, the timing determination unit 14 acquires the power consumption data of the air conditioner 2 from the power measurement unit 3 also in each integration period W21, W22, W23 after the control start times t21, t22, t23. And the timing determination part 14 integrates the reduction amount of the power consumption after control start time in each integration period W21, W22, W23 (S32). That is, power consumption immediately before the set temperature is changed from the target temperature Tm1 to the target temperature Tm2, and power consumption in each integration period W21, W22, W23 after the set temperature is changed from the target temperature Tm1 to the target temperature Tm2. (The power consumption in the hatched areas P21, P22, P23 in FIGS. 9A to 9C). Each integration period W21, W22, W23 is set to the same time length.
　次に、タイミング決定部１４は、制御開始時刻ｔ２１，ｔ２２，ｔ２３のうち、各積算期間Ｗ２１，Ｗ２２，Ｗ２３における消費電力の低減量のうち最も大きな積算値をもたらす制御開始時刻を、所定期間Ｗｓ内の新たな制御開始時刻ｔ１に設定する（Ｓ３３）。 Next, the timing determination unit 14 sets the control start time that provides the largest integrated value among the reduction amounts of power consumption in the respective integration periods W21, W22, and W23 among the control start times t21, t22, and t23 for a predetermined period Ws. Is set to a new control start time t1 (S33).
　このようにして変更された制御開始時刻ｔ１は、所定期間Ｗｓ内で省エネルギー制御による最も大きい省エネルギー効果をもたらす時刻になる。また、制御開始時刻ｔ２１，ｔ２２，ｔ２３後の各積算期間Ｗ２１，Ｗ２２，Ｗ２３における消費電力データを用いるので、制御開始時刻ｔ２１，ｔ２２，ｔ２３における省エネルギー効果の推定精度が向上し、より適切な制御開始時刻ｔ１を設定することができる。 The control start time t1 changed in this way is the time that brings the greatest energy saving effect by the energy saving control within the predetermined period Ws. Further, since the power consumption data in each integration period W21, W22, W23 after the control start time t21, t22, t23 is used, the estimation accuracy of the energy saving effect at the control start time t21, t22, t23 is improved, and more appropriate control is performed. A start time t1 can be set.
　なお、他の構成は、実施形態１と同様であり、説明は省略する。 Other configurations are the same as those in the first embodiment, and a description thereof will be omitted.
　また、上述の各実施形態において、電力以外のガス、熱等を空調機器２の使用エネルギーとして用いてもよい。 Further, in each of the above-described embodiments, gas other than electric power, heat, or the like may be used as energy used for the air conditioner 2.
　本発明を幾つかの好ましい実施形態について記述したが、この発明の本来の精神および範囲、即ち請求の範囲を逸脱することなく、当業者によって様々な修正および変形が可能である。 While the invention has been described in terms of several preferred embodiments, various modifications and variations can be made by those skilled in the art without departing from the true spirit and scope of the invention, ie, the claims.
