実施の形態１．
　図１は、実施の形態１に係る空気調和装置管理システムＡの構成を示す図である。図１に示すように、電気機器である空気調和装置管理システムＡは、集中管理システム１及び空気調和装置Ｂを有する。空気調和装置管理システムＡには、電力監視装置５が接続されている。 Embodiment 1.
FIG. 1 is a diagram showing a configuration of an air conditioner management system A according to the first embodiment. As shown in FIG. 1, the air conditioner management system A, which is an electric device, has a centralized control system 1 and an air conditioner B. A power monitoring device 5 is connected to the air conditioner management system A.
　空気調和装置Ｂは、室外機２並びに室外機２に接続された室内機３Ａ、室内機３Ｂ、室内機３Ｃ、室内機３Ｄ、室内機３Ｅ及び室内機３Ｆを有する。室内機３Ａ、室内機３Ｂ及び室内機３Ｃは、室外機２に直列に接続されている。室内機３Ｄ、室内機３Ｅ及び室内機３Ｆは、室外機２に直列に接続されている。なお、実施の形態１においては、６台の室内機３Ａ～３Ｆを示しているが、これに限られるものではない。室内機３Ａ～３Ｆを区別する必要がない場合、各室内機３Ａ～３Ｆを室内機３とも呼ぶ。実施の形態１においては、６つのエリアがある。６つのエリアには、室内機３Ａ～３Ｆがそれぞれ配置されている。室内機３Ａ～３Ｆには、起動の優先順位が設定される。優先順位は、事前に設定され、又は環境データにより動的に変更される。「環境データ」は、例えば、各室内機３Ａ～３Ｆが設置されたエリアの室内温度である。環境データは、各室内機３Ａ～３Ｆの吸込温度、各室内機３Ａ～３Ｆの設定温度と室内温度との差、又はこれらと風速との組み合わせを含みうる。環境データは、後述する状態データの内容データに含まれていても良い。 The air conditioner B includes an outdoor unit 2 and an indoor unit 3A, an indoor unit 3B, an indoor unit 3C, an indoor unit 3D, an indoor unit 3E, and an indoor unit 3F connected to the outdoor unit 2. The indoor unit 3A, the indoor unit 3B, and the indoor unit 3C are connected in series to the outdoor unit 2. The indoor unit 3D, the indoor unit 3E, and the indoor unit 3F are connected in series to the outdoor unit 2. In the first embodiment, six indoor units 3A to 3F are shown, but the present invention is not limited to this. When it is not necessary to distinguish between the indoor units 3A to 3F, each indoor unit 3A to 3F is also referred to as an indoor unit 3. In the first embodiment, there are six areas. Indoor units 3A to 3F are arranged in each of the six areas. The activation priority is set for the indoor units 3A to 3F. Priority is preset or dynamically changed by environmental data. The "environmental data" is, for example, the indoor temperature of the area where each indoor unit 3A to 3F is installed. The environmental data may include the suction temperature of each indoor unit 3A to 3F, the difference between the set temperature of each indoor unit 3A to 3F and the indoor temperature, or a combination of these and the wind speed. The environmental data may be included in the content data of the state data described later.
　室外機２は室内機３に対して冷媒を供給する。冷媒としては、例えばＲ４１０Ａなどを用いる。室外機２は、内部に、熱交換器を有する。室外機２の熱交換器は、内部に冷媒を流し、冷媒と室外の空気又は水との熱交換を行う。室内機３は、内部に、熱交換器を有する。室内機３の熱交換器は、内部に冷媒を流し、冷媒と室内の空気との熱交換を行う。また、室外機２は、各室内機３Ａ～３Ｆと通信可能に接続されている。 The outdoor unit 2 supplies the refrigerant to the indoor unit 3. As the refrigerant, for example, R410A or the like is used. The outdoor unit 2 has a heat exchanger inside. The heat exchanger of the outdoor unit 2 flows a refrigerant inside, and exchanges heat between the refrigerant and outdoor air or water. The indoor unit 3 has a heat exchanger inside. The heat exchanger of the indoor unit 3 flows a refrigerant inside, and exchanges heat between the refrigerant and the indoor air. Further, the outdoor unit 2 is communicably connected to each of the indoor units 3A to 3F.
　集中管理システム１は、空気調和装置Ｂの室外機２及び室内機３のそれぞれと通信を行う。集中管理システム１は、空気調和装置Ｂの室外機２から、室外機２の運態を示す状態データを取得する。集中管理システム１は、空気調和装置Ｂの室内機３Ａから室内機３Ａの運転状態を示す状態データ、室内機３Ｂから室内機３Ｂの運転状態を示す状態データ及び室内機３Ｃから室内機３Ｃの運転状態を示す状態データを取得する。また、集中管理システム１は、空気調和装置Ｂの室内機３Ｄから室内機３Ｄの運転状態を示す状態データ、室内機３Ｅから室内機３Ｅの運転状態を示す状態データ及び室内機３Ｆから室内機３Ｆの運転状態を示す状態データを取得する。 The centralized management system 1 communicates with each of the outdoor unit 2 and the indoor unit 3 of the air conditioner B. The centralized management system 1 acquires state data indicating the state of operation of the outdoor unit 2 from the outdoor unit 2 of the air conditioner B. The centralized management system 1 includes state data indicating the operating state of the indoor unit 3A from the indoor unit 3A of the air conditioner B, state data indicating the operating state of the indoor unit 3B to the indoor unit 3B, and operation of the indoor unit 3C from the indoor unit 3C. Acquires state data indicating the state. Further, the centralized management system 1 includes state data indicating the operating state of the indoor unit 3D from the indoor unit 3D of the air conditioner B, state data indicating the operating state of the indoor unit 3E from the indoor unit 3E, and indoor unit 3F to the indoor unit 3F. Acquires state data indicating the operating state of.
　「状態データ」は、内容項目と、データ内容とを含む。内容項目は、状態データの種別を示す情報であり、データ内容は運転状態の詳細を示す種々のデータである。状態データの種別には、「運転」、「停止」、室外機運転周波数が含まれる。 "Status data" includes content items and data content. The content item is information indicating the type of state data, and the data content is various data indicating the details of the operating state. The types of state data include "run", "stop", and outdoor unit operating frequency.
　集中管理システム１は、ユーザーからの操作入力を受け付け、必要に応じて、操作入力の内容を室外機２と室内機３とに送信する。集中管理システム１は、電力監視装置５と通信を行うことで、空気調和装置Ｂの室外機２及び室内機３の消費電力量の値を電力監視装置５から取得する。例えば、スマートメータのような電線を介して数値のやり取りを実施する方法、一定量消費された段階でステップ信号を出力し、集中管理システム１側でステップの回数を保存する等がある。なお、ここで、電力監視装置５が計測する消費電力量の値は、累計値である。そのため、或る期間に消費された消費電力量を求める場合には、当該期間の終了時の消費電力量の値から、当該期間の開始時の消費電力量の値を減算して、それらの消費電力量の値の差分を求める。 The centralized management system 1 receives operation input from the user and transmits the content of the operation input to the outdoor unit 2 and the indoor unit 3 as necessary. The centralized management system 1 acquires the value of the power consumption of the outdoor unit 2 and the indoor unit 3 of the air conditioner B from the power monitoring device 5 by communicating with the power monitoring device 5. For example, there is a method of exchanging numerical values via an electric wire such as a smart meter, a step signal is output when a certain amount is consumed, and the number of steps is stored on the centralized management system 1 side. Here, the value of the power consumption measured by the power monitoring device 5 is a cumulative value. Therefore, when calculating the amount of power consumption consumed in a certain period, the value of the amount of power consumption at the start of the period is subtracted from the value of the amount of power consumption at the end of the period, and those consumptions are obtained. Find the difference between the electric energy values.
　集中管理システム１は、室外機２及び室内機３のそれぞれから収集した状態データ、及び電力監視装置５から収集した空気調和装置Ｂの消費電力量の値を、後述する集中管理システム１のデータベース部１３（図２参照）に格納する。 The centralized management system 1 records the state data collected from each of the outdoor unit 2 and the indoor unit 3 and the value of the power consumption of the air conditioner B collected from the power monitoring device 5 in the database unit of the centralized management system 1, which will be described later. It is stored in 13 (see FIG. 2).
　電力監視装置５は、空気調和装置Ｂの消費電力量の値を測定する装置の集合体である。電力会社は、電気料金を請求するために１台以上の電力量計を設備毎に設置する。大規模な設備であれば、１００Ｖ、２００Ｖ、６６００Ｖ等の使用電圧毎に電力量計が設置される場合もある。電力監視装置５は、このような電力量計を含む。電力監視装置５は、空気調和装置Ｂの室外機２及び室内機３の消費電力量の値を、計量器などのセンサーで計測する。 The power monitoring device 5 is an aggregate of devices that measure the value of the power consumption of the air conditioner B. The electric power company installs one or more electricity meters for each facility in order to charge the electricity bill. If it is a large-scale facility, a watt-hour meter may be installed for each working voltage such as 100V, 200V, 6600V. The power monitoring device 5 includes such a power meter. The power monitoring device 5 measures the value of the power consumption of the outdoor unit 2 and the indoor unit 3 of the air conditioner B with a sensor such as a measuring instrument.
　図２は、実施の形態１に係る空気調和装置管理システムＡの集中管理システム１の機能ブロック図である。同図に示すように、集中管理システム１は、受信データ処理部１１、データ解析部１２、データベース部１３、優先順位計算部１４、通信部１５、送信データ処理部１６、状態監視部１７及び表示部１８を備えている。 FIG. 2 is a functional block diagram of the centralized management system 1 of the air conditioner management system A according to the first embodiment. As shown in the figure, the centralized management system 1 includes a received data processing unit 11, a data analysis unit 12, a database unit 13, a priority calculation unit 14, a communication unit 15, a transmission data processing unit 16, a status monitoring unit 17, and a display. The unit 18 is provided.
　通信部１５は、電力監視装置５から、空気調和装置Ｂの室外機２及び室内機３の消費電力量の値を受信する。また、通信部１５は、室外機２から、室外機２の状態を示す状態データを受信する。通信部１５は、室内機３から、室内機３の状態を示す状態データを受信する。通信部１５は、受信した状態データを受信データ処理部１１に送る。 The communication unit 15 receives the value of the power consumption of the outdoor unit 2 and the indoor unit 3 of the air conditioner B from the power monitoring device 5. Further, the communication unit 15 receives state data indicating the state of the outdoor unit 2 from the outdoor unit 2. The communication unit 15 receives state data indicating the state of the indoor unit 3 from the indoor unit 3. The communication unit 15 sends the received state data to the reception data processing unit 11.
　受信データ処理部１１は、通信部１５から受信した状態データを、内容項目とデータ内容とに分割したのち、データ解析部１２に送る。 The received data processing unit 11 divides the state data received from the communication unit 15 into content items and data contents, and then sends the status data to the data analysis unit 12.
　データ解析部１２は、受信データ処理部１１から受信した状態データの内容項目及びデータ内容を、データベース部１３に記憶させるための整形処理を行う。 The data analysis unit 12 performs formatting processing for storing the content items and data contents of the state data received from the received data processing unit 11 in the database unit 13.
　データベース部１３は、データ解析部１２によって整形処理された状態データの内容項目及びデータ内容を記憶する。また、データベース部１３は、通信部１５が受信した空気調和装置Ｂの消費電力量の値を記憶する。さらに、データベース部１３は、優先順位計算部１４で計算された空気調和装置Ｂの室内機３の優先順位を記憶する。 The database unit 13 stores the content items and data contents of the state data formatted by the data analysis unit 12. Further, the database unit 13 stores the value of the power consumption of the air conditioner B received by the communication unit 15. Further, the database unit 13 stores the priority of the indoor unit 3 of the air conditioner B calculated by the priority calculation unit 14.
　優先順位計算部１４は、空気調和装置Ｂの室内機３の優先順位を事前に設定し、又は、環境変化によって動的に再設定する。図１に示すように、１つの室外機２に複数の室内機３が接続されている場合、複数の室内機３の優先順位は、複数の室内機３の状態データの内容データに含まれる環境データに基づいて決定される。室外機２の故障は、接続される全ての室内機３の運転に影響を及ぼすからである。また、図１の室外機２及び室内機３の組み合わせが、さらに１セットある場合、この１セットの室内機３の優先順位を室内機３の優先順位よりも高くしても良い。 The priority calculation unit 14 sets the priority of the indoor unit 3 of the air conditioner B in advance, or dynamically resets it according to an environmental change. As shown in FIG. 1, when a plurality of indoor units 3 are connected to one outdoor unit 2, the priority of the plurality of indoor units 3 is included in the content data of the state data of the plurality of indoor units 3. Determined based on data. This is because the failure of the outdoor unit 2 affects the operation of all the connected indoor units 3. Further, when there is one set of combinations of the outdoor unit 2 and the indoor unit 3 in FIG. 1, the priority of the indoor unit 3 in this set may be higher than the priority of the indoor unit 3.
　室内機３の優先順位を事前に設定する場合とは、明らかに室内機３の優先順位が決まっている場合に相当する。例えば、空気調和装置Ｂの室内機３が配置される設備において、サーバー室、事務所、廊下のエリアがあったとすると設備を維持するためには、（高）サーバー室　＞　事務所　＞　廊下（低）のような順番で優先順位が設定される。ただし、エリアを細分化した場合、来客用廊下エリアを事務所より優先順位を高くする等、使用される環境により優先順位は異なる。 The case where the priority of the indoor unit 3 is set in advance corresponds to the case where the priority of the indoor unit 3 is clearly decided. For example, in the equipment where the indoor unit 3 of the air conditioner B is arranged, if there is an area of a server room, an office, and a corridor, in order to maintain the equipment, the (high) server room> office> corridor (low). ) Are set in order of priority. However, if the area is subdivided, the priority will differ depending on the environment in which it is used, such as giving the corridor area for visitors a higher priority than the office.
　環境によって優先順位を再設定する場合とは、優先順位計算部１４が、データベース部１３に格納されている状態データの内容データに含まれる環境データに基づいて、優先順位を再設定する場合である。例えば、室温と室内機３の設定温度との差がある場合に優先順位の再設定が行なわれる。優先順位計算部１４は、状態データに含まれる環境データに基づいて、室内機３の優先順位を再設定する。 The case of resetting the priority depending on the environment is a case where the priority calculation unit 14 resets the priority based on the environment data included in the content data of the state data stored in the database unit 13. .. For example, when there is a difference between the room temperature and the set temperature of the indoor unit 3, the priority is reset. The priority calculation unit 14 resets the priority of the indoor unit 3 based on the environmental data included in the state data.
　状態監視部１７は、データ解析部１２によって整形処理されてデータベース部１３に記憶された状態データの内容項目及びデータ内容に基づいて、空気調和装置Ｂの状態を監視する。状態監視部１７は、室外機２及び室内機３の状態を監視するために、定期的に、送信データ処理部１６に対して、状態データを要求するための指令を送信する。 The state monitoring unit 17 monitors the state of the air conditioner B based on the content items and data contents of the state data that have been shaped by the data analysis unit 12 and stored in the database unit 13. The status monitoring unit 17 periodically transmits a command for requesting status data to the transmission data processing unit 16 in order to monitor the status of the outdoor unit 2 and the indoor unit 3.
　状態監視部１７は、データベース部１３に格納された室内機３の優先順位に基づいて、制限付きでの運転指令を送信データ処理部１６及び通信部１５を介して室外機２及び室内機３に送信する。 The condition monitoring unit 17 sends a limited operation command to the outdoor unit 2 and the indoor unit 3 via the transmission data processing unit 16 and the communication unit 15 based on the priority of the indoor unit 3 stored in the database unit 13. Send.
　制限付きでの運転指令とは、例えば、室外機２においては暖房運転時に蒸発温度を上げる制御及び圧縮機の最大周波数制限があり、室内機３においては設定温度シフト及び強制サーモＯＦＦがある。 The operation command with restrictions includes, for example, the outdoor unit 2 has a control to raise the evaporation temperature during heating operation and the maximum frequency limit of the compressor, and the indoor unit 3 has a set temperature shift and forced thermo-off.
　状態監視部１７は、空気調和装置Ｂが運転を開始した段階でデータベース部１３に蓄積されている消費電力量の変化を求める。すなわち、状態監視部１７は、空気調和装置Ｂの現在の消費電力の値と前回の消費電力の値との差を求める。次に、求められた消費電力の値の差に基づいて今後の消費電力の値を計算する。そして、計算された今後の消費電力の値と規定値の電力の値との差（絶対値）が基準値以内の場合、優先順位計算部１４により空気調和装置Ｂの室内機３に決定された優先順位が最も高いのに対して、運転指令を出力する。ここで、規定値の電力とは、停電により制限される電力をいう。また、「基準値」とは、規定値の電力の所定パーセントである。 The condition monitoring unit 17 obtains a change in the amount of power consumption stored in the database unit 13 when the air conditioner B starts operation. That is, the condition monitoring unit 17 obtains the difference between the current power consumption value of the air conditioner B and the previous power consumption value. Next, the future power consumption value is calculated based on the difference between the obtained power consumption values. Then, when the difference (absolute value) between the calculated future power consumption value and the specified power value is within the reference value, the priority calculation unit 14 determines the indoor unit 3 of the air conditioner B. The operation command is output for the highest priority. Here, the specified value of electric power means the electric power limited by a power failure. The "reference value" is a predetermined percentage of the specified value of electric power.
　状態監視部１７は、消費電力量の値の変化が、決められた規定値の電力量に対して余力がある場合、次に高い優先順位の室内機３に対し、送信データ処理部１６、通信部１５を介して制御（Ａ）での運転指令を送信する。 The condition monitoring unit 17 communicates with the transmission data processing unit 16 to the indoor unit 3 having the next highest priority when the change in the power consumption value has a margin for the determined specified value of the power amount. The operation command in the control (A) is transmitted via the unit 15.
　一般的に室内機３の送風運転が最も消費電力量が少なく、冷房もしくは暖房で設定温度と室温との差が大きい場合、最も消費電力が多くなる傾向がある。室外機２の蒸発温度シフト及び圧縮機の最大周波数制限の強さにより消費電力量を抑えることが可能である。 In general, the ventilation operation of the indoor unit 3 has the lowest power consumption, and when the difference between the set temperature and the room temperature is large in cooling or heating, the power consumption tends to be the highest. It is possible to suppress the power consumption by shifting the evaporation temperature of the outdoor unit 2 and the strength of the maximum frequency limitation of the compressor.
　送信データ処理部１６は、状態監視部１７からの指令に応じて、通信部１５を介して、室外機２及び室内機３に対して、状態要求を送信する。室外機２及び室内機３は、通信部１５からの状態要求を受信すると、状態要求に応じて、自身の状態データを通信部１５に対して送信する。 The transmission data processing unit 16 transmits a status request to the outdoor unit 2 and the indoor unit 3 via the communication unit 15 in response to a command from the status monitoring unit 17. When the outdoor unit 2 and the indoor unit 3 receive the status request from the communication unit 15, the outdoor unit 2 and the indoor unit 3 transmit their own status data to the communication unit 15 in response to the status request.
　表示部１８は、ユーザーからの要求に応じて、優先順位計算部１４の優先順位結果及びデータベース部１３に記憶された種々のデータを、表示画面に表示する。表示部１８は、ディスプレイなどの表示機器を備えている。 The display unit 18 displays the priority result of the priority calculation unit 14 and various data stored in the database unit 13 on the display screen in response to a request from the user. The display unit 18 includes a display device such as a display.
　次に、集中管理システム１のハードウェア構成について簡単に説明する。実施の形態１に係る集中管理システム１における各機能は、処理回路によって実現される。各機能を実現する処理回路は、専用のハードウェアであってもよく、メモリに格納されるプログラムを実行するプロセッサであってもよい。 Next, the hardware configuration of the centralized management system 1 will be briefly explained. Each function in the centralized management system 1 according to the first embodiment is realized by a processing circuit. The processing circuit that realizes each function may be dedicated hardware or a processor that executes a program stored in the memory.
　処理回路が専用のハードウェアである場合、処理回路は、例えば、単一回路、複合回路、プログラム化したプロセッサ、並列プログラム化したプロセッサ、ＡＳＩＣ（Ａｐｐｌｉｃａｔｉｏｎ　Ｓｐｅｃｉｆｉｃ　Ｉｎｔｅｇｒａｔｅｄ　Ｃｉｒｃｕｉｔ）、ＦＰＧＡ（Ｆｉｅｌｄ　Ｐｒｏｇｒａｍｍａｂｌｅ　Ｇａｔｅ　Ａｒｒａｙ）、又はこれらを組み合わせたものが該当する。受信データ処理部１１、データ解析部１２、データベース部１３、優先順位計算部１４、通信部１５、送信データ処理部１６、状態監視部１７及び表示部１８の各部の機能それぞれを個別の処理回路で実現してもよいし、各部の機能をまとめて処理回路で実現してもよい。 When the processing circuit is dedicated hardware, the processing circuit may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array). , Or a combination of these. Each function of the received data processing unit 11, the data analysis unit 12, the database unit 13, the priority calculation unit 14, the communication unit 15, the transmission data processing unit 16, the status monitoring unit 17, and the display unit 18 is performed by an individual processing circuit. It may be realized, or the functions of each part may be collectively realized by a processing circuit.

　図３は、実施の形態１に係る空気調和装置管理システムＡの集中管理システム１のデータベース部１３に格納される室内機３の異常を判断するテーブル２０を示す図である。図３に示すように、設定温度と室温との差の変化が大きく、かつ室温の変化が小さい場合、判断対象となる室内機３は、ステージＳ＿１と判断される。ステージＳ＿１は、判断対象となる室内機３の能力不足又は機器異常の可能性があることを示す。設定温度と室温との差が大きく、かつ室温変化が大きい場合、判断対象となる室内機３は、ステージＳ＿２と判断される。ステージＳ＿２は、判断対象となる室内機３が正常であることを示す。設定温度と室温の差が小さく、かつ温度変化が小さい場合、判断対象となる室内機３は、ステージＳ＿３と判断される。ステージＳ＿３は、判断対象となる室内機３の温度変化から温度維持に制御をシフトすることから温度変化が小さくても異常とは判別しない。設定温度と室温との差が小さく、かつ温度変化が大きい場合、判断対象となる室内機３のステージＳ＿４と判断される。ステージＳ＿４は、判断対象となる室内機３が能力過多もしくは他の要因により温度制御ができていることを示す。判断対象がステージＳ＿４の室内機３については、使用電力を削除することが可能である。 FIG. 3 is a diagram showing a table 20 for determining an abnormality of the indoor unit 3 stored in the database unit 13 of the centralized management system 1 of the air conditioner management system A according to the first embodiment. As shown in FIG. 3, when the change in the difference between the set temperature and the room temperature is large and the change in the room temperature is small, the indoor unit 3 to be determined is determined to be the stage S_1. The stage S_1 indicates that there is a possibility that the capacity of the indoor unit 3 to be determined is insufficient or the equipment is abnormal. When the difference between the set temperature and the room temperature is large and the room temperature change is large, the indoor unit 3 to be determined is determined to be the stage S_2. The stage S_2 indicates that the indoor unit 3 to be determined is normal. When the difference between the set temperature and the room temperature is small and the temperature change is small, the indoor unit 3 to be determined is determined to be the stage S_3. Since the stage S_3 shifts control from the temperature change of the indoor unit 3 to be determined to the temperature maintenance, even if the temperature change is small, it is not determined to be abnormal. When the difference between the set temperature and the room temperature is small and the temperature change is large, it is determined that the stage S_4 of the indoor unit 3 to be determined. The stage S_4 indicates that the indoor unit 3 to be determined is capable of temperature control due to excessive capacity or other factors. For the indoor unit 3 whose determination target is stage S_4, it is possible to delete the power consumption.
　次に、実施の形態１に係る集中管理システム１の動作について説明する。図４は、実施の形態１に係る集中管理システム１の動作について説明するためのフローチャートである。 Next, the operation of the centralized management system 1 according to the first embodiment will be described. FIG. 4 is a flowchart for explaining the operation of the centralized management system 1 according to the first embodiment.
　ステップＳ１において、状態監視部１７は、データベース部１３に記憶された「現在の消費電力量の値」と「前回の消費電力量の値」との差を計算し、時間で割ることで、単位時間あたりに増加した消費電力の値（Ｗ）を求める。また、状態監視部１７は、各室内機３の「室温」の変化及び「室温と設定温度との差」の変化を求める。なお、状態監視部１７は、一般的に暖房のような温度を上げる制御の際は、設定温度－室温、一般的に冷房のような温度を下げる制御の際は、室温－設定温度とし、プラスとマイナスとの符号の意味を合わせておく。 In step S1, the state monitoring unit 17 calculates the difference between the "current power consumption value" and the "previous power consumption value" stored in the database unit 13, and divides by the time to unit. The value (W) of the increased power consumption per hour is obtained. Further, the condition monitoring unit 17 obtains a change in the "room temperature" of each indoor unit 3 and a change in the "difference between the room temperature and the set temperature". The condition monitoring unit 17 is generally set to a set temperature-room temperature when controlling to raise the temperature such as heating, and is generally set to room temperature-set temperature when controlling to lower the temperature such as cooling. Match the meanings of the signs of and minus.
　次に、状態監視部１７は、Ｓ１において算出された室温の差の変化及び各室内機３の室温と設定温度との差の変化に基づいて、図４のテーブル２０に従って、室内機３がステージＳ＿２にあるかを室内機３毎に判断する（ステップＳ２）。ステップＳ２において、判断対象となる室内機３のステージが「ステージＳ＿２」の場合（ステップＳ２のＹＥＳ）、ステップＳ３に移行する。判断対象となる室内機３のステージが「ステージＳ＿１」、「ステージＳ＿３」又は「ステージＳ＿４」の場合（ステップＳ２のＮＯ）、ステップＳ９に移行する。 Next, in the condition monitoring unit 17, the indoor unit 3 is staged according to the table 20 of FIG. 4 based on the change in the difference in room temperature calculated in S1 and the change in the difference between the room temperature and the set temperature of each indoor unit 3. It is determined for each indoor unit 3 whether it is in S_2 (step S2). In step S2, when the stage of the indoor unit 3 to be determined is “stage S_2” (YES in step S2), the process proceeds to step S3. When the stage of the indoor unit 3 to be determined is "stage S_1", "stage S_3" or "stage S_4" (NO in step S2), the process proceeds to step S9.
　ステップＳ３では、状態監視部１７は、今後の消費電力の値が規定値の電力量の値を超える可能性があるか否かを判断する（ステップＳ３）。具体的には、状態監視部１７は、ステップＳ１において求められた増加した消費電力の値に基づいて今後の消費電力の値を計算し、計算された今後の消費電力の値と、規定値の電力の値との差（絶対値）が基準値以内であるかを判断する。 In step S3, the condition monitoring unit 17 determines whether or not the value of future power consumption may exceed the value of the specified value of electric energy (step S3). Specifically, the state monitoring unit 17 calculates the future power consumption value based on the increased power consumption value obtained in step S1, and the calculated future power consumption value and the specified value. Judge whether the difference (absolute value) from the power value is within the reference value.
　今後の消費電力の値と、規定値の電力の値との差が基準値以内の場合、すなわち、今後の消費電力の値が規定値の電力の値を超える可能性がある場合（ステップＳ３のＹＥＳ）、ステップＳ５に移行する。今後の消費電力の値と、規定値の電力の値との差が基準値より大きい場合（ステップＳ３のＮＯ）、ステップＳ４に移行する。 When the difference between the future power consumption value and the specified value power value is within the reference value, that is, when the future power consumption value may exceed the specified value power value (step S3). YES), the process proceeds to step S5. When the difference between the future power consumption value and the specified power value is larger than the reference value (NO in step S3), the process proceeds to step S4.
　ステップＳ４では、集中管理システム１は、空気調和装置Ｂの運転を継続して実施する。 In step S4, the centralized management system 1 continuously operates the air conditioner B.
　ステップＳ５では、今後の消費電力の値と規定値の電力の値との差（絶対値）が基準値以内の場合、すなわち、今後の消費電力が設定値に対して十分に余裕がある場合、制御方式を変更するか否かを判断する。制御方式とは、前述の圧縮機の最大周波数制限及び室内機３の送風運転に相当する。ステップＳ５では、制御が瞬間的な電力超過の可能性がある制御の場合、例えば暖房２８℃で室外機２を動かす制御は、制御方式を変更する必要がない（ステップＳ５のＮＯ）として、ステップＳ７に移行する。瞬間的な電力超過の可能性が低い場合（ステップＳ５のＹＥＳ）、制御方式を変更する必要があるとしてステップＳ６に移行する。 In step S5, when the difference (absolute value) between the future power consumption value and the specified value power value is within the reference value, that is, when the future power consumption has a sufficient margin with respect to the set value. Determine whether to change the control method. The control method corresponds to the maximum frequency limitation of the compressor and the blowing operation of the indoor unit 3 described above. In step S5, when the control is a control in which there is a possibility of a momentary power excess, for example, the control for operating the outdoor unit 2 at a heating temperature of 28 ° C. does not need to change the control method (NO in step S5). Move to S7. When the possibility of momentary power overrun is low (YES in step S5), the process proceeds to step S6 because it is necessary to change the control method.
　ステップＳ６では、空気調和装置Ｂの室外機２及び室内機３の制御方式を変更する。ステップＳ７では、次の優先順位の室内機３の運転を行うかを判断する。次の優先順位の室内機３の運転は、判断対象となる室内機３が上記「ステージＳ＿３」になった場合に行われる。ステップＳ７において、次の優先順位の室内機３の運転を行うと判断された場合（ステップＳ７のＹＥＳ）、次の優先順位の室内機３に運転指令を送信する（ステップＳ８）。ステップＳ８において、運転開始（停止→運転）の場合、制限付き指令での運転を指示する。その後、次のループでステップＳ６になった際に、制限付き指令の度合いを弱くする。例えば、強制サーモＯＦＦ→温度シフト→制限なし、のように制御する。 In step S6, the control method of the outdoor unit 2 and the indoor unit 3 of the air conditioner B is changed. In step S7, it is determined whether to operate the indoor unit 3 having the next priority. The operation of the indoor unit 3 having the next priority is performed when the indoor unit 3 to be determined becomes the above-mentioned "stage S_3". When it is determined in step S7 that the indoor unit 3 having the next priority is to be operated (YES in step S7), an operation command is transmitted to the indoor unit 3 having the next priority (step S8). In step S8, when the operation is started (stop → operation), the operation with the restricted command is instructed. After that, when step S6 is reached in the next loop, the degree of the restricted command is weakened. For example, it is controlled as forced thermo OFF → temperature shift → no limit.
　ステップＳ９では、前述の「ステージＳ＿１」、「ステージＳ＿３」、「ステージＳ＿４」ごとに優先順位の入れ替えが行なわれる。各ステージの優先順位は、「ステージＳ＿１」＞「ステージＳ＿３」＞「ステージＳ＿４」となる。 In step S9, the priorities are exchanged for each of the above-mentioned "stage S_1", "stage S_3", and "stage S_4". The priority of each stage is "stage S_1"> "stage S_3"> "stage S_4".
　ステップＳ１０では、ステップＳ９での優先順位の入れ替えにより確定した順番に再度運転指令が送信される。 In step S10, the operation command is transmitted again in the order determined by the replacement of the priorities in step S9.
　従って、実施の形態１の空気調和装置Ｂの集中管理システム１によれば、今後の消費電力と規定値の電力の値との差が基準値以内の場合、決定された電気機器の優先順位に従って運転指令を出力する。これにより、限られた電力で空気調和装置Ｂの運転を維持することができる。 Therefore, according to the centralized management system 1 of the air conditioner B of the first embodiment, when the difference between the future power consumption and the specified power value is within the reference value, the priority of the determined electric equipment is followed. Output the operation command. As a result, the operation of the air conditioner B can be maintained with a limited electric power.
実施の形態２．
　実施の形態１では空気調和装置Ｂの一般的な機能である温度制御の観点で記述した。実施の形態２は、空気調和装置Ｂの代わりに電気機器である換気機器を管理する換気機器管理システムに関する。実施の形態２の換気機器管理システムの集中管理システム１は、換気機器が配置されたエリアの有害気体（例えば、二酸化炭素）濃度に基づいて、換気機器の起動の優先順位を決定する点が実施の形態１と異なる。また、集中管理システム１は、決定された優先順位に従って、換気機器の制御、例えば、風量の制御を行なう。 Embodiment 2.
In the first embodiment, it is described from the viewpoint of temperature control, which is a general function of the air conditioner B. The second embodiment relates to a ventilation equipment management system that manages a ventilation equipment which is an electric equipment instead of the air conditioner B. The centralized management system 1 of the ventilation equipment management system of the second embodiment is implemented in that the priority of starting the ventilation equipment is determined based on the concentration of harmful gas (for example, carbon dioxide) in the area where the ventilation equipment is arranged. Is different from Form 1. Further, the centralized management system 1 controls the ventilation equipment, for example, the air volume according to the determined priority.
　図５は、実施の形態２に係る換気機器管理システムＤの構成を示す図である。なお、図１と同一部分には、同一符号を付し、その説明を省略する。図５に示すように、換気機器管理システムＤは、換気機器４Ａ、換気機器４Ｂ、換気機器４Ｃ、換気機器４Ｄ、換気機器４Ｅ及び換気機器４Ｆを有する。換気機器４Ａ～４Ｆは、集中管理システム１に接続される。 FIG. 5 is a diagram showing the configuration of the ventilation equipment management system D according to the second embodiment. The same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. As shown in FIG. 5, the ventilation device management system D includes a ventilation device 4A, a ventilation device 4B, a ventilation device 4C, a ventilation device 4D, a ventilation device 4E, and a ventilation device 4F. The ventilation devices 4A to 4F are connected to the centralized management system 1.
　なお、実施の形態２においては、６台の換気機器４Ａ～４Ｆを示しているが、これに限られるものではない。換気機器４Ａ～４Ｆを区別する必要がない場合、各換気機器４Ａ～４Ｆを換気機器４とも呼ぶ。実施の形態２においては、６つのエリアがある。６つのエリアには、換気機器４Ａ～４Ｆがそれぞれ配置されている。換気機器４Ａ～４Ｆには、起動の優先順位が設定される。優先順位は、事前に設定され、又は環境データにより動的に変更される。 Note that, in the second embodiment, six ventilation devices 4A to 4F are shown, but the present invention is not limited to this. When it is not necessary to distinguish the ventilation devices 4A to 4F, each ventilation device 4A to 4F is also referred to as a ventilation device 4. In the second embodiment, there are six areas. Ventilation devices 4A to 4F are arranged in each of the six areas. The activation priority is set for the ventilation devices 4A to 4F. Priority is preset or dynamically changed by environmental data.
　換気機器４Ａ～４Ｆは、集中管理システム１に接続される。集中管理システム１は、換気機器４Ａから送信される換気機器４Ａのエリアの有害気体濃度に基づいて、換気機器４Ａの優先順位を決定する。また、集中管理システム１は、換気機器４Ｂから送信される換気機器４Ｂのエリアの有害気体濃度に基づいて、換気機器４Ｂの優先順位を決定する。集中管理システム１は、換気機器４Ｃから送信される換気機器４Ｃのエリアの有害気体濃度に基づいて、換気機器４Ｃの優先順位を決定する。集中管理システム１は、換気機器４Ｄから送信される換気機器４Ｄのエリアの有害気体濃度に基づいて、換気機器４Ｄの優先順位を決定する。集中管理システム１は、換気機器４Ｅから送信される換気機器４Ｅのエリアの有害気体濃度に基づいて、換気機器４Ｅの優先順位を決定する。集中管理システム１は、換気機器４Ｆから送信される換気機器４Ｆのエリアの有害気体濃度に基づいて、換気機器４Ｆの優先順位を決定する。そして、集中管理システム１は、実施の形態１と同様に、決定された優先順位に従って換気機器４Ａ～４Ｆを制御する。優先度は、エリアで検出された有害気体濃度と、そのエリアの有害気体濃度の目標値との差に基づいて決定されても良い。実施の形態２の集中管理システム１によれば、実施の形態１と同様に、今後の消費電力と規定値の電力の値との差が基準値以内の場合、決定された電気機器の優先順位に従って運転指令を出力する。これにより、限られた電力で換気機器４の運転を維持することができる。 Ventilation devices 4A-4F are connected to the centralized management system 1. The centralized control system 1 determines the priority of the ventilation device 4A based on the concentration of harmful gas in the area of the ventilation device 4A transmitted from the ventilation device 4A. Further, the centralized management system 1 determines the priority of the ventilation device 4B based on the concentration of harmful gas in the area of the ventilation device 4B transmitted from the ventilation device 4B. The centralized control system 1 determines the priority of the ventilation device 4C based on the concentration of harmful gas in the area of the ventilation device 4C transmitted from the ventilation device 4C. The centralized control system 1 determines the priority of the ventilation device 4D based on the concentration of harmful gas in the area of the ventilation device 4D transmitted from the ventilation device 4D. The centralized control system 1 determines the priority of the ventilation device 4E based on the concentration of harmful gas in the area of the ventilation device 4E transmitted from the ventilation device 4E. The centralized management system 1 determines the priority of the ventilation device 4F based on the concentration of harmful gas in the area of the ventilation device 4F transmitted from the ventilation device 4F. Then, the centralized management system 1 controls the ventilation devices 4A to 4F according to the determined priority, as in the first embodiment. The priority may be determined based on the difference between the harmful gas concentration detected in the area and the target value of the harmful gas concentration in the area. According to the centralized management system 1 of the second embodiment, as in the first embodiment, when the difference between the future power consumption and the specified power value is within the reference value, the determined priority of the electric equipment is obtained. The operation command is output according to the above. As a result, the operation of the ventilation device 4 can be maintained with limited electric power.
実施の形態３．
　実施の形態３は、空気調和装置Ｂと換気機器４とが混在する空気調和装置管理システムＡである。換気機器４は、空気調和装置Ｂと連動する。 Embodiment 3.
The third embodiment is an air conditioner management system A in which an air conditioner B and a ventilation device 4 are mixed. The ventilation device 4 is interlocked with the air conditioner B.
　図６は、実施の形態３に係る空気調和装置管理システムＡの構成を示す図である。なお、図１及び図５と同一部分には、同一符号を付し、その説明を省略する。図６において、換気機器４Ａは室内機３Ａと連動する。換気機器４Ｂは室内機３Ｂと連動する。換気機器４Ｃは室内機３Ｃと連動する。 FIG. 6 is a diagram showing the configuration of the air conditioner management system A according to the third embodiment. The same parts as those in FIGS. 1 and 5 are designated by the same reference numerals, and the description thereof will be omitted. In FIG. 6, the ventilation device 4A is interlocked with the indoor unit 3A. The ventilation device 4B is linked with the indoor unit 3B. The ventilation device 4C is linked with the indoor unit 3C.
　実施の形態３において、優先順位の算出は、実施の形態１の計算方法と同様である。集中管理システム１は、換気機器４の優先順位は考慮せずに、システムの制御を行なう。実施の形態３の空気調和装置管理システムＡによれば、室内機３と換気機器４とが混在するシステムにおいても実施の形態１と同様の効果を得ることができる。また、実施の形態３の空気調和装置管理システムＡによれば、同じエリア設置された室内機３と換気機器４とを、室内機３の優先順位にしたがって同時に運転できる。 In the third embodiment, the calculation of the priority order is the same as the calculation method of the first embodiment. The centralized management system 1 controls the system without considering the priority of the ventilation device 4. According to the air conditioner management system A of the third embodiment, the same effect as that of the first embodiment can be obtained even in a system in which the indoor unit 3 and the ventilation device 4 coexist. Further, according to the air conditioner management system A of the third embodiment, the indoor unit 3 and the ventilation device 4 installed in the same area can be operated at the same time according to the priority of the indoor unit 3.
実施の形態４．
　実施の形態４は、空気調和装置Ｂと換気機器４とが混在する空気調和装置管理システムＡである。換気機器４は、空気調和装置Ｂと連動せず、空気調和装置Ｂとは別に制御される。空気調和装置Ｂと換気機器４とは、互いに依存関係はない。 Embodiment 4.
The fourth embodiment is an air conditioner management system A in which an air conditioner B and a ventilation device 4 are mixed. The ventilation device 4 is not interlocked with the air conditioner B and is controlled separately from the air conditioner B. The air conditioner B and the ventilation device 4 are not dependent on each other.
　実施の形態４において、集中管理システム１は、優先順位の算出にあたり実施の形態２及び実施の形態３を実施し、室内機３については温度を使用し、換気機器４については有害気体の濃度を使用して、優先順位を決定する。 In the fourth embodiment, the centralized management system 1 implements the second and third embodiments in calculating the priority, uses the temperature for the indoor unit 3, and determines the concentration of harmful gas for the ventilation device 4. Use to determine priorities.
　集中管理システム１は、空気調和装置Ｂの優先順位と換気機器４の優先順位とをそれぞれ算出する。空気調和装置Ｂの優先順位は、換気機器４の優先順位とは異なるパラメータで計算される。従って、同じ優先順位であっても重みが異なる。例えば、室温と設定温度との差が５度ある室内機３の優先順位と、室内二酸化炭素濃度と目標二酸化炭素濃度との差が３００ｐｐｍの換気機器４の優先順位とが同じ優先順位の場合、点数方式で優先順位を変更する。 The centralized management system 1 calculates the priority of the air conditioner B and the priority of the ventilation device 4, respectively. The priority of the air conditioner B is calculated by a parameter different from the priority of the ventilation device 4. Therefore, the weights are different even if they have the same priority. For example, when the priority of the indoor unit 3 having a difference of 5 degrees between the room temperature and the set temperature and the priority of the ventilation device 4 having a difference of 300 ppm between the indoor carbon dioxide concentration and the target carbon dioxide concentration are the same. Change the priority by the point method.
　図７は、実施の形態４に係る空気調和装置管理システムＡの構成を示す図である。なお、図１及び図５と同一部分には、同一符号を付し、その説明を省略する。図７において、換気機器４Ａ、換気機器４Ｂ及び換気機器４Ｃは、集中管理システム１に接続される。集中管理システム１は、室内機３Ａ～室内機３Ｃ及び換気機器４Ａ～換気機器４Ｃの優先順位を制御する。 FIG. 7 is a diagram showing the configuration of the air conditioner management system A according to the fourth embodiment. The same parts as those in FIGS. 1 and 5 are designated by the same reference numerals, and the description thereof will be omitted. In FIG. 7, the ventilation device 4A, the ventilation device 4B, and the ventilation device 4C are connected to the centralized management system 1. The centralized management system 1 controls the priority order of the indoor unit 3A to the indoor unit 3C and the ventilation device 4A to the ventilation device 4C.
　ここでは、説明の便宜上、室内機３Ａ、室内機３Ｂ、換気機器４Ａ及び換気機器４Ｂの優先順位の変更について説明する。
　集中管理システム１は、以下の方法で室内機３Ａ、室内機３Ｂ、換気機器４Ａ及び換気機器４Ｂの優先順位を変更する。
　集中管理システム１は、室内機３Ａ、室内機３Ｂ、換気機器４Ａ及び換気機器４Ｂの優先順位の点数を以下の式により算出する。
　（点数）　＝　Δ　／　ΔＭａｘ　×　１００
ここで、
　　　　　　　Δ　：　目標値との差
　　　　　ΔＭａｘ：　Δの許容最大値 Here, for convenience of explanation, the change of the priority order of the indoor unit 3A, the indoor unit 3B, the ventilation device 4A, and the ventilation device 4B will be described.
The centralized management system 1 changes the priority order of the indoor unit 3A, the indoor unit 3B, the ventilation device 4A, and the ventilation device 4B by the following method.
The centralized management system 1 calculates the priority points of the indoor unit 3A, the indoor unit 3B, the ventilation device 4A, and the ventilation device 4B by the following formula.
(Score) = Δ / ΔMax × 100
here,
Δ: Difference from the target value ΔMax: Maximum allowable value of Δ
　例えば、室内機３Ａ、室内機３Ｂ、換気機器４Ａ及び換気機器４Ｂが下記のような状態であるとする。
・室内機３Ａ
目標値との差　５度差、目標値との差の許容最大値　１０度差
・室内機３Ｂ
目標値との差　３度差、目標値との差の許容最大値　１０度差
・換気機器４Ａ
目標値との差　３００ｐｐｍ、目標値との差の許容最大値　５００ｐｐｍ
・換気機器４Ｂ
目標値との差　２００ｐｐｍ、目標値との差の許容最大値　５００ｐｐｍ
　この場合、これらの点数は以下のように計算される。
　室内機３Ａの点数　＝　５（度差）／１０×１００　＝５０点
　室内機３Ｂの点数　＝　３（度差）／１０×１００　＝３０点
　換気機器４Ａの点数　＝　３００（ｐｐｍ差）／５００×１００　＝６０点
　換気機器４Ｂの点数　＝　２００（ｐｐｍ差）／５００×１００　＝４０点
　なお、点数は、実環境での差分が許容数値を超える場合は１００点として計算される。 For example, it is assumed that the indoor unit 3A, the indoor unit 3B, the ventilation device 4A, and the ventilation device 4B are in the following states.
・ Indoor unit 3A
Difference from the target value 5 degrees difference, maximum allowable difference from the target value 10 degrees difference, indoor unit 3B
Difference from the target value 3 degrees difference, allowable maximum difference from the target value 10 degrees difference ・ Ventilation equipment 4A
Difference from target value 300ppm, maximum allowable difference from target value 500ppm
・ Ventilation equipment 4B
Difference from target value 200ppm, maximum allowable difference from target value 500ppm
In this case, these points are calculated as follows.
Indoor unit 3A score = 5 (degree difference) / 10 × 100 = 50 points Indoor unit 3B score = 3 (degree difference) / 10 × 100 = 30 points Ventilation equipment 4A score = 300 (ppm difference) / 500 × 100 = 60 points Ventilation equipment 4B score = 200 (ppm difference) / 500 × 100 = 40 points The score is calculated as 100 points if the difference in the actual environment exceeds the permissible value.
　集中管理システム１は、室内機３Ａ、室内機３Ｂ、換気機器４Ａ及び換気機器４Ｂの点数の計算結果に従って、これらの優先順位を以下のように決定する。
　換気機器４Ａ　＞　室内機３Ａ　＞　換気機器４Ｂ　＞　室内機３Ｂ
　なお、目標値との差Δは運転により変化する。従って、再計算のタイミングで、優先順位は、入れ替わる可能性がある。 The centralized management system 1 determines the priority order of the indoor unit 3A, the indoor unit 3B, the ventilation device 4A, and the ventilation device 4B according to the calculation results of the scores as follows.
