The indoor suction port 17 is attached to the housing 12 and forms a duct connection flange that sucks air from the room.

Based on the detected CO 2 concentration value, the drive command signal to the supply fan drive circuit 34 and the drive command signal to the exhaust fan drive circuit 35 are generated and transmitted.
　なお、個別リモートコントローラー８と駆動制御装置２０との通信方式と、集中コントローラー９と駆動制御装置２０との通信方式とが同じであれば、リモートコントローラー通信回路３８が集中コントローラー通信回路３９を兼ねていてもよい。すなわち、リモートコントローラー通信回路３８と集中コントローラー通信回路３９とが一体形成されていてもよい。このような構成とすると、駆動制御装置２０を小型化可能となる。 If the communication method between the individual remote controller 8 and the drive control device 20 is the same as the communication method between the centralized controller 9 and the drive control device 20, the remote controller communication circuit 38 also serves as the centralized controller communication circuit 39. May be. That is, the remote controller communication circuit 38 and the centralized controller communication circuit 39 may be integrally formed. With such a configuration, the drive control device 20 can be downsized.
　なお、室外温湿度センサー２６は、温度と湿度の双方を検知可能な一体型センサーとしているが、本発明はこれに限定されず、温度センサーと湿度センサーとが別々に設けられていてもよい。温度センサーと湿度センサーとが別々に設けられる場合には、室外温湿度センサー検知回路３６の構成もこれと整合するように適宜変更する。 The outdoor temperature / humidity sensor 26 is an integrated sensor capable of detecting both temperature and humidity, but the present invention is not limited to this, and the temperature sensor and the humidity sensor may be provided separately. In the case where the temperature sensor and the humidity sensor are provided separately, the configuration of the outdoor temperature / humidity sensor detection circuit 36 is appropriately changed so as to be consistent therewith.
　図４は、駆動制御装置２０の制御動作の一例を示すフローチャートである。図４に示す制御動作では、給気用送風機２４に対して間欠運転制御を行っており、排気用送風機２５の動作については説明を省略する。排気用送風機２５の動作について、給気用送風機２４を常時停止又は間欠運転する際には、排気用送風機２５の動作設定を常時運転としてもよいし、給気用送風機２４に連動させて常時停止又は間欠運転としてもよい。 FIG. 4 is a flowchart showing an example of the control operation of the drive control device 20. In the control operation shown in FIG. 4, intermittent operation control is performed on the air supply fan 24, and the description of the operation of the exhaust fan 25 is omitted. Regarding the operation of the exhaust fan 25, when the air supply fan 24 is always stopped or intermittently operated, the operation setting of the exhaust fan 25 may be always operated, or it is always stopped in conjunction with the air supply fan 24. Or it is good also as intermittent operation.
　排気用送風機２５を常時運転とする場合には、給気口から自然に空気を導入して排気ファンで排気することができ、第三種換気による継続的な換気が可能である。又は、給気用送風機２４の停止に連動して排気用送風機２５を停止とする場合には、排気量と給気量のバランスが確保される。そのため、換気対象空間である室内における、換気に起因したドアの開閉の不具合を防止することが可能である。なお、排気用送風機２５の動作設定は、個別リモートコントローラー８又は集中コントローラー９から操作可能としてもよい。 When the exhaust fan 25 is always operated, air can be naturally introduced from the air supply port and exhausted by the exhaust fan, and continuous ventilation by the third type ventilation is possible. Alternatively, when the exhaust fan 25 is stopped in conjunction with the stop of the air supply fan 24, a balance between the exhaust amount and the air supply amount is secured. Therefore, it is possible to prevent a door opening / closing failure caused by ventilation in a room that is a ventilation target space. The operation setting of the exhaust fan 25 may be operable from the individual remote controller 8 or the centralized controller 9.
　図４において、駆動制御装置２０が個別リモートコントローラー８からの運転信号又は集中コントローラー９からの運転操作情報を受信すると、制御フローが開始する。制御フローが開始すると、駆動制御装置２０は、給気用送風機２４を一定時間運転する（Ｓ４１）。ここでは、一定時間として３分を例示している。なお、Ｓ４１は、室外温湿度センサー２６の室外温湿度検知値の安定のために行う動作であり、設置環境によってこの一定時間は調整される。従って、室外温湿度検知値が待ち時間なく安定するのであれば、一定時間を０としてもよい。次に、駆動制御装置２０は、室外温湿度センサー２６の室外温湿度検知値である検知温度Ｔｏａが第１の規定温度Ｔ１℃未満であるか否か判定する（Ｓ４２）。検知温度Ｔｏａが第１の規定温度Ｔ１℃未満である場合（Ｓ４２：Ｙｅｓ）には、図４の端子Ａから図５のＳ４０１へ進み、検知温度Ｔｏａが第１の規定温度Ｔ１℃未満でない場合（Ｓ４２：Ｎｏ）には、Ｓ４３へ進む。 4, when the drive control device 20 receives an operation signal from the individual remote controller 8 or driving operation information from the centralized controller 9, the control flow starts. When the control flow is started, the drive control device 20 operates the air supply fan 24 for a predetermined time (S41). Here, 3 minutes is illustrated as the fixed time. Note that S41 is an operation performed to stabilize the outdoor temperature / humidity detection value of the outdoor temperature / humidity sensor 26, and this predetermined time is adjusted depending on the installation environment. Therefore, if the outdoor temperature / humidity detection value is stable without waiting time, the predetermined time may be set to zero. Next, the drive control device 20 determines whether or not the detected temperature Toa, which is the outdoor temperature / humidity detection value of the outdoor temperature / humidity sensor 26, is lower than the first specified temperature T1 ° C. (S42). When the detected temperature Toa is lower than the first specified temperature T1 ° C. (S42: Yes), the process proceeds from the terminal A in FIG. 4 to S401 in FIG. 5, and the detected temperature Toa is not lower than the first specified temperature T1 ° C. In (S42: No), it progresses to S43.
　Ｓ４２でＮｏに分岐すると、駆動制御装置２０は、室外温湿度センサー２６の室外温湿度検知値である検知湿度Ｈｏａが第１の規定湿度Ｈ１％以上であるか否かを判定する（Ｓ４３）。検知湿度Ｈｏａが第１の規定湿度Ｈ１％以上である場合（Ｓ４３：Ｙｅｓ）には図４の端子Ｂから図６のＳ４２１へ進み、検知湿度Ｈｏａが第１の規定湿度Ｈ１％以上でない、すなわち第１の規定湿度Ｈ１％未満である場合（Ｓ４３：Ｎｏ）にはＳ４４へ進む。 When branching to No in S42, the drive control device 20 determines whether or not the detected humidity Hoa, which is the outdoor temperature / humidity detection value of the outdoor temperature / humidity sensor 26, is equal to or higher than the first specified humidity H1% (S43). When the detected humidity Hoa is equal to or higher than the first specified humidity H1% (S43: Yes), the process proceeds from the terminal B in FIG. 4 to S421 in FIG. 6, and the detected humidity Hoa is not equal to or higher than the first specified humidity H1%. When it is less than the first specified humidity H1% (S43: No), the process proceeds to S44.
　Ｓ４３でＮｏに分岐すると、駆動制御装置２０は、間欠運転制御状態を終了とし（Ｓ４４）、集中コントローラー９に間欠運転制御状態情報を送信し（Ｓ４５）、給気用送風機２４を常時運転とし（Ｓ４６）、ステップＳ４２へ戻る。 When branching to No in S43, the drive control device 20 ends the intermittent operation control state (S44), transmits intermittent operation control state information to the centralized controller 9 (S45), and sets the air supply fan 24 to always operate ( S46), the process returns to step S42.
　図５は、駆動制御装置２０の外気低温時の間欠運転制御の一例を示すフローチャートである。なお、図５に示すＳ４０１からＳ４０９までは、低温外気の吸込みにより空調装置１１内部、特に給気風路５１における結露を防止するために行う。外気低温時の間欠運転制御を開始すると、駆動制御装置２０は、間欠運転制御状態を「実施中」とし（Ｓ４０１）、集中コントローラー９へ間欠運転制御状態情報を送信し（Ｓ４０２）、集中コントローラー９から送信されるセンシング停止指令がオンであるか否かを判定する（Ｓ４０３）。ここで、センシング停止指令がオンである場合（Ｓ４０３：Ｙｅｓ）には、空調システム内のセンシング運転を他の空調装置１１が代表して行っていることを意味し、センシング停止指令がオンでない、すなわちオフである場合（Ｓ４０３：Ｎｏ）には、空調システム内のセンシング運転を、この駆動制御装置２０を備える空調装置１１が代表して行っていることを意味する。 FIG. 5 is a flowchart showing an example of intermittent operation control of the drive control device 20 at a low outside air temperature. Note that S401 to S409 shown in FIG. 5 are performed in order to prevent condensation in the air conditioner 11, particularly in the air supply air passage 51, by sucking in low-temperature outside air. When the intermittent operation control at the low temperature of the outside air is started, the drive control device 20 sets the intermittent operation control state to “in progress” (S401), transmits intermittent operation control state information to the centralized controller 9 (S402), and from the centralized controller 9 It is determined whether or not the transmitted sensing stop command is on (S403). Here, when the sensing stop command is on (S403: Yes), it means that the other air conditioner 11 is representatively performing the sensing operation in the air conditioning system, and the sensing stop command is not on. That is, when it is off (S403: No), it means that the sensing operation in the air conditioning system is representatively performed by the air conditioning device 11 including the drive control device 20.
　センシング停止指令がオンである場合（Ｓ４０３：Ｙｅｓ）には、給気用送風機２４は常時停止とされ（Ｓ４０４）、Ｓ４０３に戻る。すなわち、空調システム内の他の空調装置１１にセンシングを委ね、この駆動制御装置２０を備える空調装置１１は外気低温時の間欠運転制御を行わず、集中コントローラー９からのセンシング停止指令がオフになるのを待つ。センシング停止指令がオフである場合（Ｓ４０３：Ｎｏ）には、駆動制御装置２０は、集中コントローラー９から送信されるセンシング停止指令のオンオフ変化の有無を判定する（Ｓ４０５）。センシング停止指令のオンオフ変化ありの場合（Ｓ４０５：Ｙｅｓ）には、空調システム内の他の空調装置１１において間欠運転制御が終了し、空調システム全体で間欠運転制御状態が解除されたことを意味する。一方、センシング停止指令のオンオフ変化なしの場合（Ｓ４０５：Ｎｏ）には、センシング停止指令がオフ状態を継続していれば、この駆動制御装置２０を備える空調装置１１が、空調システム内で最初に間欠運転制御を開始することを意味する。 If the sensing stop command is on (S403: Yes), the air supply fan 24 is always stopped (S404), and the process returns to S403. That is, sensing is entrusted to other air conditioners 11 in the air conditioning system, and the air conditioner 11 including the drive control device 20 does not perform intermittent operation control when the outside temperature is low, and the sensing stop command from the centralized controller 9 is turned off. Wait for. If the sensing stop command is off (S403: No), the drive control device 20 determines whether there is an on / off change in the sensing stop command transmitted from the centralized controller 9 (S405). When the sensing stop command is turned on / off (S405: Yes), it means that the intermittent operation control is terminated in the other air conditioners 11 in the air conditioning system, and the intermittent operation control state is released in the entire air conditioning system. . On the other hand, in the case where there is no change in the sensing stop command (S405: No), if the sensing stop command continues in the off state, the air conditioner 11 including this drive control device 20 is the first in the air conditioning system. It means starting intermittent operation control.
　センシング停止指令のオンオフ変化なしの場合（Ｓ４０５：Ｎｏ）には、空調装置１１は給気用送風機２４をＴａ分間だけ停止させ、Ｔｂ分間だけ運転する間欠運転制御を行い（Ｓ４０６）、間欠運転制御が終了したか否か判定する（Ｓ４０７）。ここで、Ｔｂ分間の運転は、室外温度を検知するセンシング運転である。 When there is no change in the sensing stop command (S405: No), the air conditioner 11 stops the air supply fan 24 for Ta minutes and performs intermittent operation control for operation for Tb (S406), and intermittent operation control. It is determined whether or not (S407). Here, the operation for Tb is a sensing operation for detecting the outdoor temperature.
　なお、ここでは、Ｔ１＝－１０℃、Ｔａ＝６０分、Ｔｂ＝３分とするが、本発明はこれに限定されるものではない。間欠運転制御が終了していない場合（Ｓ４０７：Ｎｏ）には、Ｓ４０３へ戻る。間欠運転制御が終了している場合（Ｓ４０７：Ｙｅｓ）には、Ｓ４２へ戻る。 Here, T1 = −10 ° C., Ta = 60 minutes, and Tb = 3 minutes, but the present invention is not limited to this. If the intermittent operation control has not ended (S407: No), the process returns to S403. If the intermittent operation control has been completed (S407: Yes), the process returns to S42.
　センシング停止指令のオンオフ変化ありの場合（Ｓ４０５：Ｙｅｓ）には、間欠運転制御状態は終了とし（Ｓ４０８）、給気用送風機２４をＴｂ分間運転する（Ｓ４０９）。なお、Ｓ４０９は、室外温湿度センサー２６の室外温湿度検知値の安定が目的であり、設置環境によってこの一定時間は調整される。従って、室外温湿度検知値が待ち時間なく安定するのであれば、一定時間を０としてもよい。 If the sensing stop command is on / off (S405: Yes), the intermittent operation control state is terminated (S408), and the air supply fan 24 is operated for Tb (S409). The purpose of S409 is to stabilize the outdoor temperature / humidity detection value of the outdoor temperature / humidity sensor 26, and this fixed time is adjusted depending on the installation environment. Therefore, if the outdoor temperature / humidity detection value is stable without waiting time, the predetermined time may be set to zero.
　図６は、駆動制御装置２０の外気高湿度時の間欠運転制御の一例を示すフローチャートである。なお、図６に示すＳ４２１からＳ４２９までは、高湿度外気の吸込みにより空調装置１１内部、特に給気風路５１における結露を防止するために行う。外気高湿度時の間欠運転制御を開始すると、駆動制御装置２０は、間欠運転制御状態を「実施中」とし（Ｓ４２１）、集中コントローラー９へ間欠運転制御状態情報を送信し（Ｓ４２２）、集中コントローラー９から送信されるセンシング停止指令がオンであるか否かを判定する（Ｓ４２３）。ここで、センシング停止指令がオンである場合（Ｓ４２３：Ｙｅｓ）には、空調システム内のセンシング運転を他の空調装置１１が代表して行っていることを意味し、センシング停止指令がオンでない、すなわちオフである場合（Ｓ４２３：Ｎｏ）には、空調システム内のセンシング運転を、この駆動制御装置２０を備える空調装置１１が代表して行っていることを意味する。 FIG. 6 is a flowchart showing an example of intermittent operation control of the drive control device 20 when the outside air is at high humidity. Note that steps S421 to S429 shown in FIG. 6 are performed in order to prevent dew condensation in the air conditioner 11, particularly in the supply air passage 51, due to the intake of high humidity outside air. When the intermittent operation control at the time of outdoor high humidity is started, the drive control device 20 sets the intermittent operation control state to “in progress” (S421), transmits intermittent operation control state information to the centralized controller 9 (S422), and the centralized controller 9 It is determined whether the sensing stop command transmitted from is on (S423). Here, when the sensing stop command is on (S423: Yes), it means that the other air conditioner 11 is representatively performing the sensing operation in the air conditioning system, and the sensing stop command is not on. That is, when it is off (S423: No), it means that the air conditioning apparatus 11 provided with this drive control apparatus 20 is representatively performing the sensing operation in the air conditioning system.
　センシング停止指令がオンである場合（Ｓ４２３：Ｙｅｓ）には、給気用送風機２４を常時停止とし（Ｓ４２４）、Ｓ４２３に戻る。すなわち、空調システム内の他の空調装置１１にセンシングを委ね、この駆動制御装置２０を備える空調装置１１は外気高湿度時の間欠運転制御を行わず、集中コントローラー９からのセンシング停止指令がオフになるのを待つ。センシング停止指令がオフである場合（Ｓ４２３：Ｎｏ）には、駆動制御装置２０は、集中コントローラー９から送信されるセンシング停止指令のオンオフ変化の有無を判定する（Ｓ４２５）。センシング停止指令のオンオフ変化ありの場合（Ｓ４２５：Ｙｅｓ）には、空調システム内の他の空調装置１１において間欠運転制御が終了し、空調システム全体で間欠運転制御状態が解除されたことを意味し、センシング停止指令のオンオフ変化なしの場合（Ｓ４２５：Ｎｏ）には、センシング停止指令がオフ状態を継続していれば、この駆動制御装置２０を備える空調装置１１が、空調システム内で最初に間欠運転制御を開始することを意味する。 If the sensing stop command is ON (S423: Yes), the air supply fan 24 is always stopped (S424), and the process returns to S423. That is, sensing is entrusted to other air conditioners 11 in the air conditioning system, and the air conditioner 11 including the drive control device 20 does not perform intermittent operation control when the outside air is at high humidity, and the sensing stop command from the centralized controller 9 is turned off. Wait for When the sensing stop command is off (S423: No), the drive control device 20 determines whether there is an on / off change in the sensing stop command transmitted from the centralized controller 9 (S425). When the sensing stop command is turned on / off (S425: Yes), it means that the intermittent operation control is terminated in the other air conditioners 11 in the air conditioning system, and the intermittent operation control state is released in the entire air conditioning system. In the case where there is no on / off change of the sensing stop command (S425: No), if the sensing stop command continues in the off state, the air conditioner 11 including the drive control device 20 is intermittently first in the air conditioning system. This means starting operation control.
　センシング停止指令のオンオフ変化なしの場合（Ｓ４２５：Ｎｏ）には、給気用送風機２４をＴｃ分間だけ停止させ、Ｔｄ分間だけ運転させる間欠運転制御を行い（Ｓ４２６）、間欠運転制御が終了したか否か判定する（Ｓ４２７）。ここで、Ｔｄ分間の運転は、室外湿度を検知するセンシング運転である。 If the sensing stop command is not turned on or off (S425: No), intermittent operation control is performed in which the air supply fan 24 is stopped for Tc minutes and operated for Td minutes (S426). It is determined whether or not (S427). Here, the operation for Td minutes is a sensing operation for detecting outdoor humidity.
　なお、ここでは、Ｈ１＝９０％、Ｔｃ＝８０分、Ｔｄ＝３分とするが、本発明はこれに限定されるものではない。間欠運転制御が終了していない場合（Ｓ４２７：Ｎｏ）には、Ｓ４２３へ戻る。間欠運転制御が終了している場合（Ｓ４２７：Ｙｅｓ）には、Ｓ４２へ戻る。 Note that, here, H1 = 90%, Tc = 80 minutes, and Td = 3 minutes, but the present invention is not limited to this. If the intermittent operation control has not ended (S427: No), the process returns to S423. When the intermittent operation control is finished (S427: Yes), the process returns to S42.
　センシング停止指令のオンオフ変化ありの場合（Ｓ４２５：Ｙｅｓ）には、間欠運転制御状態は終了とし（Ｓ４２８）、給気用送風機２４をＴｄ分間運転する（Ｓ４２９）。なお、Ｓ４２９は、室外温湿度センサー２６の室外温湿度検知値の安定が目的であり、設置環境によってこの一定時間は調整され、室外温湿度検知値が待ち時間なく安定するのであれば、一定時間を０としてもよい。 If the sensing stop command is on / off (S425: Yes), the intermittent operation control state is ended (S428), and the air supply fan 24 is operated for Td (S429). Note that S429 is for the purpose of stabilizing the outdoor temperature / humidity detection value of the outdoor temperature / humidity sensor 26, and this fixed time is adjusted according to the installation environment. May be 0.
　図７は、集中コントローラー９の制御動作の一例を示すフローチャートである。図７において、集中コントローラー９の電源がオンされると、集中コントローラー９は、代表センシング装置を「なし」として初期化する（Ｓ５０１）。次に、集中コントローラー９は、代表センシング装置ではない空調装置１１から間欠運転制御状態が「実施中」との通知があるか否か判定する（Ｓ５０２）。この間欠運転制御状態が「実施中」との通知は、Ｓ４０２又はＳ４２２にて送信されたものである。間欠運転制御状態が「実施中」との通知がある場合（Ｓ５０２：Ｙｅｓ）には、集中コントローラー９は、代表センシング装置があるか否か判定する（Ｓ５０３）。代表センシング装置がある場合（Ｓ５０３：Ｙｅｓ）には、集中コントローラー９は、センシング停止指令をオンする送信を行い、すなわちセンシングを停止する指令を代表センシング装置に送信し（Ｓ５０４）、代表センシング装置がＳ５０２で通知した装置となるよう更新する（Ｓ５０５）。 FIG. 7 is a flowchart showing an example of the control operation of the centralized controller 9. In FIG. 7, when the power of the centralized controller 9 is turned on, the centralized controller 9 initializes the representative sensing device as “none” (S501). Next, the centralized controller 9 determines whether or not there is a notification from the air conditioner 11 that is not the representative sensing device that the intermittent operation control state is “in progress” (S502). The notification that the intermittent operation control state is “in progress” is transmitted in S402 or S422. When there is a notification that the intermittent operation control state is “in progress” (S502: Yes), the centralized controller 9 determines whether there is a representative sensing device (S503). When there is a representative sensing device (S503: Yes), the centralized controller 9 transmits to turn on a sensing stop command, that is, transmits a command to stop sensing to the representative sensing device (S504). The device is updated to be the device notified in S502 (S505).
　なお、間欠運転制御状態が「実施中」である空調装置１１が増えることは、センシング停止指令がオンであることを送信する空調装置１１が増えること、及び代表センシング装置が間欠運転制御状態を終了とする場合に集中コントローラー９からセンシング停止指令がオフであることを通知する空調装置１１が増えることを意味する。 Note that the increase in the number of air conditioners 11 whose intermittent operation control state is “in progress” indicates that the number of air conditioners 11 that transmit that the sensing stop command is ON increases, and the representative sensing device ends the intermittent operation control state. This means that the number of air conditioners 11 notifying that the sensing stop command is off from the centralized controller 9 increases.
　また、代表センシング装置がない場合（Ｓ５０３：Ｎｏ）には、集中コントローラー９は、センシング停止指令を送信することなく代表センシング装置がＳ５０２で通知した装置となるよう更新する（Ｓ５０５）。 If there is no representative sensing device (S503: No), the centralized controller 9 updates the representative sensing device to be the device notified in S502 without sending a sensing stop command (S505).
　すなわち、集中コントローラー９は、代表センシング装置が、最後に間欠運転制御を開始した空調装置１１となるよう設定する。これにより、先に間欠運転制御を行っていた空調装置１１に対してセンシング運転を開始させず、不要なセンシング運転の回避により消費電力を抑えることができる。 That is, the centralized controller 9 sets the representative sensing device to be the air conditioner 11 that finally started the intermittent operation control. Thereby, it is possible to suppress power consumption by avoiding unnecessary sensing operation without starting the sensing operation with respect to the air conditioner 11 that has previously performed the intermittent operation control.
　間欠運転制御状態が「実施中」との通知がない場合（Ｓ５０２：Ｎｏ）にも、集中コントローラー９は、代表センシング装置があるか否か判定する（Ｓ５０６）。代表センシング装置がある場合（Ｓ５０６：Ｙｅｓ）には、集中コントローラー９は、代表センシング装置である空調装置１１から間欠運転制御状態が終了したとの通知がなされたか否か判定する（Ｓ５０７）。代表センシング装置である空調装置１１から間欠運転制御状態が終了したとの通知がある場合（Ｓ５０７：Ｙｅｓ）には、センシング停止指令オンを送信したすべての空調装置１１に対してセンシング停止指令をオフするよう送信し（Ｓ５０８）、Ｓ５０１へ戻る。また、代表センシング装置がない場合（Ｓ５０６：Ｎｏ）又は代表センシング装置である空調装置１１から間欠運転制御状態が終了したとの通知がない場合（Ｓ５０７：Ｎｏ）には、Ｓ５０２へ戻る。 Even when there is no notification that the intermittent operation control state is “in progress” (S502: No), the centralized controller 9 determines whether there is a representative sensing device (S506). If there is a representative sensing device (S506: Yes), the centralized controller 9 determines whether or not a notification that the intermittent operation control state has been completed has been made from the air conditioner 11 that is the representative sensing device (S507). When there is a notification from the air conditioner 11 that is the representative sensing device that the intermittent operation control state has ended (S507: Yes), the sensing stop command is turned off for all the air conditioners 11 that have transmitted the sensing stop command ON. (S508), and the process returns to S501. When there is no representative sensing device (S506: No), or when there is no notification that the intermittent operation control state has been completed from the air conditioner 11 that is the representative sensing device (S507: No), the process returns to S502.
　図８，９，１０は、本発明の実施の形態１にかかる空調システムの制御シーケンスの一例を示す図である。図８，９，１０には、空調装置１１ａ，１１ｂ，１１ｒ，１１ｓが外気低温時の間欠運転制御を行う際の集中コントローラー９と空調装置１１ａ，１１ｂ，１１ｒ，１１ｓとの間の制御シーケンスを示している。図８，９，１０において、図８のＡ１，Ｂ１，Ｃ１，Ｄ１，Ｅ１は各々図９のＡ１，Ｂ１，Ｃ１，Ｄ１，Ｅ１に続き、図９のＡ２，Ｂ２，Ｃ２，Ｄ２，Ｅ２は各々図１０のＡ２，Ｂ２，Ｃ２，Ｄ２，Ｅ２に続く。 8, 9, and 10 are diagrams illustrating an example of a control sequence of the air conditioning system according to the first exemplary embodiment of the present invention. 8, 9, and 10 show control sequences between the centralized controller 9 and the air conditioners 11a, 11b, 11r, and 11s when the air conditioners 11a, 11b, 11r, and 11s perform intermittent operation control when the outside temperature is low. ing. 8, 9, and 10, A1, B1, C1, D1, and E1 of FIG. 8 follow A1, B1, C1, D1, and E1 of FIG. 9, respectively, and A2, B2, C2, D2, and E2 of FIG. Each follows A2, B2, C2, D2, E2 in FIG.
　なお、図８，９，１０においては、図４から７に示す各ステップについて、空調装置１１ａにおけるステップではＳ４０１ａのようにステップ番号に符号ａを付し、空調装置１１ｂにおけるステップではＳ４０１ｂのようにステップ番号に符号ｂを付し、空調装置１１ｒにおけるステップではＳ４０１ｒのようにステップ番号に符号ｒを付し、空調装置１１ｓにおけるステップではＳ４０１ｓのようにステップ番号に符号ｓを付する。なお、以下の説明において、制御シーケンスについては同様に符号を付するものとする。 8, 9, and 10, for each step shown in FIGS. 4 to 7, the step number in the air conditioner 11 a is assigned a step number as in S <b> 401 a, and the step in the air conditioner 11 b is as S <b> 401 b. The step number is assigned b, the step in the air conditioner 11r is given the step number as in S401r, and the step in the air conditioner 11s is given the step number as S401s. In the following description, reference numerals are similarly assigned to the control sequences.
　なお、図８，９，１０における制御シーケンスは、空調システム内で複数台の空調装置１１が外気低温時の間欠運転制御を行う場合に、最後に外気低温時の間欠運転制御を開始した空調装置１１が代表センシング装置となり、この代表センシング装置が間欠運転制御を終了するまでは、間欠運転制御状態が「実施中」である他の空調装置１１が給気用送風機２４を常時停止とする状態を維持し、センシング運転を行わないことを示している。なお、ここでは、最後に外気低温時の間欠運転制御を開始した空調装置１１は、空調装置１１ｓである。 8, 9, and 10, when a plurality of air conditioners 11 perform intermittent operation control at a low temperature of the outside air in the air conditioning system, the air conditioner 11 that finally started the intermittent operation control at a low temperature of the outside air is used. Until this representative sensing device ends the intermittent operation control, the other air conditioner 11 whose intermittent operation control state is “in progress” maintains the state where the air supply fan 24 is always stopped. This indicates that sensing operation is not performed. Here, the air conditioner 11 that finally started the intermittent operation control at the time of low outside air temperature is the air conditioner 11s.

Show. 11, 12, and 13, A11, B11, C11, D11, and E11 in FIG. 11 follow A11, B11, C11, D11, and E11 in FIG. 12, respectively, and A12, B12, C12, D12, and E12 in FIG. Each follows A12, B12, C12, D12, and E12 of FIG.
　なお、図１１，１２，１３における制御シーケンスは、空調システム内で複数台の空調装置１１が外気高湿度時の間欠運転制御を行う場合に、最後に外気高湿度時の間欠運転制御を開始した空調装置１１が代表センシング装置となり、この代表センシング装置が間欠運転制御を終了するまでは、間欠運転制御状態が「実施中」である他の空調装置１１が給気用送風機２４を常時停止とする状態を維持し、センシング運転を行わないことを示している。なお、ここでは、最後に外気高湿度時の間欠運転制御を開始した空調装置１１は、空調装置１１ｓである。 11, 12, and 13, the air conditioner that finally started the intermittent operation control at the time of outside air high humidity when a plurality of air conditioners 11 perform the intermittent operation control at the time of outside air high humidity in the air conditioning system. 11 is a representative sensing device, and until this representative sensing device finishes the intermittent operation control, the other air conditioner 11 whose intermittent operation control state is “in implementation” is in a state in which the air supply fan 24 is always stopped. This indicates that the sensing operation is not performed. Here, the air conditioner 11 that finally started the intermittent operation control when the outside air is high in humidity is the air conditioner 11s.
　図１４，１５，１６は、本発明の実施の形態１にかかる空調システムの制御シーケンスの一例を示す図である。図１４，１５，１６には、空調装置１１ａ，１１ｂ，１１ｒ，１１ｓが外気低温時の間欠運転制御を行う際の集中コントローラー９と空調装置１１ａ，１１ｂ，１１ｒ，１１ｓとの間の制御シーケンスを示している。図１４，１５，１６において、図１４のＡ２１，Ｂ２１，Ｃ２１，Ｄ２１，Ｅ２１は各々図１５のＡ２１，Ｂ２１，Ｃ２１，Ｄ２１，Ｅ２１に続き、図１５のＡ２２，Ｂ２２，Ｃ２２，Ｄ２２，Ｅ２２は各々図１６のＡ２２，Ｂ２２，Ｃ２２，Ｄ２２，Ｅ２２に続く。図１４，１５，１６と図８，９，１０との違いは、集中コントローラー９が代表センシング装置をビル全体ではなく、階毎に管理している点である。室外温湿度はフロアーの高低又はビルの周りの環境によって異なる場合もある。そのため、階毎に管理することで、間欠運転制御を終了可能な階において、不要な間欠運転制御を解除できない状況を回避することができる。 FIGS. 14, 15, and 16 are diagrams illustrating an example of a control sequence of the air conditioning system according to the first embodiment of the present invention. FIGS. 14, 15, and 16 show control sequences between the centralized controller 9 and the air conditioners 11a, 11b, 11r, and 11s when the air conditioners 11a, 11b, 11r, and 11s perform intermittent operation control when the outside temperature is low. ing. 14, 15, and 16, A21, B21, C21, D21, and E21 of FIG. 14 follow A21, B21, C21, D21, and E21 of FIG. 15, respectively, and A22, B22, C22, D22, and E22 of FIG. Each follows A22, B22, C22, D22, and E22 of FIG. The difference between FIGS. 14, 15, 16 and FIGS. 8, 9, 10 is that the centralized controller 9 manages the representative sensing device for each floor, not for the entire building. The outdoor temperature and humidity may vary depending on the height of the floor or the environment around the building. Therefore, by managing for each floor, it is possible to avoid a situation where unnecessary intermittent operation control cannot be canceled on a floor where intermittent operation control can be terminated.
　なお、図１４，１５，１６における制御シーケンスは、空調システム内で複数台の空調装置１１が外気低温時の間欠運転制御を行う場合に、階毎に、最後に外気低温時の間欠運転制御を開始した空調装置１１が代表センシング装置となり、この代表センシング装置が間欠運転制御を終了するまでは、間欠運転制御状態が「実施中」である他の空調装置１１が給気用送風機２４を常時停止とする状態を維持し、センシング運転を行わないことを示している。なお、ここでは、最後に外気低温時の間欠運転制御を開始した空調装置１１は、空調装置１１ｂ，空調装置１１ｓであり、他の空調装置１１は、空調装置１１ａ，１１ｒである。 In addition, the control sequence in FIG.14,15,16 started the intermittent operation control at the time of the external low temperature last for every floor | bed, when the several air conditioner 11 performs the intermittent operation control at the time of low external temperature in the air conditioning system. The air conditioner 11 becomes a representative sensing device, and the other air conditioner 11 whose intermittent operation control state is “in progress” always stops the air supply fan 24 until the representative sensing device finishes the intermittent operation control. The state is maintained and the sensing operation is not performed. Here, the air conditioner 11 that finally started the intermittent operation control at a low temperature of the outside air is the air conditioner 11b and the air conditioner 11s, and the other air conditioners 11 are the air conditioners 11a and 11r.
　図１７，１８，１９は、本発明の実施の形態１にかかる空調システムの制御シーケンスの一例を示す図である。図１７，１８，１９には、空調装置１１ａ，１１ｂ，１１ｃ，１１ｄが外気低温時の間欠運転制御を行う際の集中コントローラー９と空調装置１１ａ，１１ｂ，１１ｃ，１１ｄとの間の制御シーケンスを示している。図１７，１８，１９において、図１７のＡ３１，Ｂ３１，Ｃ３１，Ｄ３１，Ｅ３１は各々図１８のＡ３１，Ｂ３１，Ｃ３１，Ｄ３１，Ｅ３１に続き、図１８のＡ３２，Ｂ３２，Ｃ３２，Ｄ３２，Ｅ３２は各々図１９のＡ３２，Ｂ３２，Ｃ３２，Ｄ３２，Ｅ３２に続く。図１７，１８，１９と図８，９，１０との違いは、集中コントローラー９が代表センシング装置をビル全体ではなく、テナント毎に管理している点である。室外温湿度検知値は室外から空調装置までのダクト長で異なることがあり、室外温湿度検知値はテナントごとに異なることもある。そのため、代表センシング装置をテナント単位で管理することで、間欠運転制御を終了可能なテナントにおいて間欠運転制御を解除できない状況を回避することができる。 17, 18, and 19 are diagrams illustrating an example of a control sequence of the air conditioning system according to the first exemplary embodiment of the present invention. 17, 18, and 19 show a control sequence between the centralized controller 9 and the air conditioners 11a, 11b, 11c, and 11d when the air conditioners 11a, 11b, 11c, and 11d perform intermittent operation control when the outside air is cold. ing. 17, 18, and 19, A31, B31, C31, D31, and E31 in FIG. 17 follow A31, B31, C31, D31, and E31 in FIG. 18, respectively, and A32, B32, C32, D32, and E32 in FIG. Each follows A32, B32, C32, D32, and E32 in FIG. The difference between FIGS. 17, 18, and 19 and FIGS. 8, 9, and 10 is that the centralized controller 9 manages the representative sensing device for each tenant, not for the entire building. The outdoor temperature / humidity detection value may differ depending on the duct length from the outdoor to the air conditioner, and the outdoor temperature / humidity detection value may differ for each tenant. Therefore, by managing the representative sensing device in units of tenants, it is possible to avoid a situation in which intermittent operation control cannot be canceled in a tenant that can end intermittent operation control.
　なお、室内ＣＯ２濃度低下時の間欠運転制御を行う場合のように、室内の環境情報をセンシングする場合には、室内空間毎、すなわちテナント単位での管理が好ましい。なお、ここで、室内の環境情報は、室内温度、室内湿度及び室内ガス濃度を含む。 In addition, when sensing indoor environment information as in the case of performing intermittent operation control when the indoor CO 2 concentration is reduced, management in each indoor space, that is, in tenant units is preferable. Here, the indoor environmental information includes indoor temperature, indoor humidity, and indoor gas concentration.
　なお、図１７，１８，１９における制御シーケンスは、空調システム内で複数台の空調装置１１が外気低温時の間欠運転制御を行う場合に、テナント毎に、最後に外気低温時の間欠運転制御を開始した空調装置１１が代表センシング装置となり、この代表センシング装置が間欠運転制御を終了するまでは、間欠運転制御状態が「実施中」である他の空調装置１１が給気用送風機を常時停止とする状態を維持し、センシング運転を行わないことを示している。なお、ここでは、最後に外気低温時の間欠運転制御を開始した空調装置１１は、空調装置１１ｂ，空調装置１１ｄであり、他の空調装置１１は、空調装置１１ａ，１１ｃである。 17, 18, and 19, when a plurality of air conditioners 11 perform intermittent operation control when the outside temperature is low in the air conditioning system, finally, intermittent operation control when the outside temperature is low is started for each tenant. The air conditioner 11 becomes a representative sensing device, and until this representative sensing device finishes the intermittent operation control, the other air conditioner 11 whose intermittent operation control state is “in progress” always stops the air supply fan. This indicates that the sensing operation is not performed. Here, the air conditioner 11 that finally started the intermittent operation control at the time of low outside temperature is the air conditioner 11b and the air conditioner 11d, and the other air conditioners 11 are the air conditioners 11a and 11c.
　以上説明した本実施の形態１においては、ビル建物全体、階毎又はテナント毎に代表センシング装置を管理しているが、本発明はこれに限定されるものではない。ビル建物の北側と南側とに分けて管理してもよいし、インテリアゾーンとペリメータゾーンとに分けて管理してもよい。すなわち、集中コントローラー９は、管理している複数台の空調装置１１を複数のグループに分割してグループ毎に管理し、分割されたグループ内で複数台の空調装置１１が間欠運転を行う際には、グループ内において代表センシング装置を設定し、グループ内の代表センシング装置以外の空調装置１１は、間欠運転制御におけるセンシング運転を行わないように制御されてもよい。 In the first embodiment described above, the representative sensing device is managed for the entire building, for each floor, or for each tenant, but the present invention is not limited to this. It may be managed separately for the north side and the south side of the building, or may be managed separately for the interior zone and the perimeter zone. In other words, the centralized controller 9 divides the plurality of air conditioners 11 being managed into a plurality of groups and manages each group, and when the plurality of air conditioners 11 perform intermittent operation within the divided groups. May set the representative sensing device in the group, and the air conditioners 11 other than the representative sensing device in the group may be controlled not to perform the sensing operation in the intermittent operation control.
　図２０は、本発明の実施の形態１にかかる空調システムを備えるビルの他の一例を示す模式図である。図２０に示すビル１００ａは、図１に示すビル１００から、個別リモートコントローラー８ｂ，８ｄ，８ｆ，８ｈ，８ｊ，８ｍ，８ｐ，８ｓと、リモートコントローラー通信用伝送路８０ｂ，８０ｄ，８０ｆ，８０ｈ，８０ｊ，８０ｍ，８０ｐ，８０ｓと、集中コントローラー９と、集中コントローラー通信用伝送路９０と、を除いた構成である。 FIG. 20 is a schematic diagram illustrating another example of a building including the air conditioning system according to the first embodiment of the present invention. The building 100a shown in FIG. 20 is different from the building 100 shown in FIG. 1 in that the individual remote controllers 8b, 8d, 8f, 8h, 8j, 8m, 8p, 8s and the remote controller communication transmission lines 80b, 80d, 80f, 80h, The configuration is such that 80j, 80m, 80p, and 80s, the centralized controller 9, and the centralized controller communication transmission line 90 are excluded.
　具体的には、１階の北側であるテナント１北には、リモートコントローラー通信用伝送路８０ａを介して個別リモートコントローラー８ａを接続した空調装置１１ａ，１１ｂが設置されている。１階の南側であるテナント１南には、リモートコントローラー通信用伝送路８０ｃを介して個別リモートコントローラー８ｃを接続した空調装置１１ｃ，１１ｄが設置されている。また、２階の北側であるテナント２北には、リモートコントローラー通信用伝送路８０ｅを介して個別リモートコントローラー８ｅを接続した空調装置１１ｅ，１１ｆが設置されている。２階の南側であるテナント２南には、リモートコントローラー通信用伝送路８０ｇを介して個別リモートコントローラー８ｇを接続した空調装置１１ｇ，１１ｈが設置されている。また、３階の北側であるテナント３北には、リモートコントローラー通信用伝送路８０ｉを介して個別リモートコントローラー８ｉを接続した空調装置１１ｉ，１１ｊが設置されている。３階の南側であるテナント３南には、リモートコントローラー通信用伝送路８０ｋを介して個別リモートコントローラー８ｋを接続した空調装置１１ｋ，１１ｍが設置されている。また、４階の北側であるテナント４北には、リモートコントローラー通信用伝送路８０ｎを介して個別リモートコントローラー８ｎを接続した空調装置１１ｎ，１１ｐが設置されている。４階の南側であるテナント４南には、リモートコントローラー通信用伝送路８０ｒを介して個別リモートコントローラー８ｒを接続した空調装置１１ｒ，１１ｓが設置されている。 Specifically, air conditioners 11a and 11b connected to an individual remote controller 8a through a remote controller communication transmission path 80a are installed in the north of the tenant 1 on the north side of the first floor. Air conditioners 11c and 11d, to which an individual remote controller 8c is connected via a remote controller communication transmission line 80c, are installed on the south side of the tenth, which is the south side of the first floor. Further, air conditioners 11e and 11f connected to the individual remote controller 8e via the remote controller communication transmission path 80e are installed on the north side of the tenth floor, which is the north side of the second floor. Air conditioners 11g and 11h, to which an individual remote controller 8g is connected via a remote controller communication transmission line 80g, are installed on the south side of the tenth 2 which is the south side of the second floor. Further, air conditioners 11i and 11j connected to the individual remote controller 8i via the remote controller communication transmission path 80i are installed in the tenant 3 north, which is the north side of the third floor. Air conditioners 11k and 11m connected to an individual remote controller 8k via a remote controller communication transmission path 80k are installed in the south of the tenant 3 on the south side of the third floor. Further, air conditioners 11n and 11p, each having an individual remote controller 8n connected thereto via a remote controller communication transmission line 80n, are installed on the north side of the fourth floor, which is the tenant 4 north. Air conditioners 11r and 11s connected to the individual remote controller 8r via the remote controller communication transmission path 80r are installed in the south of the tenth 4 which is the south side of the fourth floor.
　図２１，２２，２３は、本発明の実施の形態１にかかる空調システムの制御シーケンスの一例を示す図である。図２１，２２，２３には、空調装置１１ａ，１１ｂ，１１ｃ，１１ｄが外気低温時の間欠運転制御を行う際の個別リモートコントローラー８ａ，８ｃと空調装置１１ａ，１１ｂ，１１ｃ，１１ｄとの間の制御シーケンスを示している。図２１，２２，２３において、図２１のＡ４１，Ｂ４１，Ｃ４１，Ｄ４１，Ｅ４１は各々図２２のＡ４１，Ｂ４１，Ｃ４１，Ｄ４１，Ｅ４１に続き、図２２のＡ４２，Ｂ４２，Ｃ４２，Ｄ４２，Ｅ４２は各々図２３のＡ４２，Ｂ４２，Ｃ４２，Ｄ４２，Ｅ４２に続く。ここで、図２１，２２，２３と図１７，１８，１９との違いは、テナント単位で代表センシング装置を判定するコントローラーが、集中コントローラー９ではなく個別リモートコントローラー８である点である。 FIGS. 21, 22, and 23 are diagrams illustrating an example of a control sequence of the air-conditioning system according to the first embodiment of the present invention. 21, 22, and 23, control between the individual remote controllers 8 a and 8 c and the air conditioners 11 a, 11 b, 11 c, and 11 d when the air conditioners 11 a, 11 b, 11 c, and 11 d perform intermittent operation control when the outside temperature is low. A sequence is shown. 21, 22, and 23, A41, B41, C41, D41, and E41 in FIG. 21 follow A41, B41, C41, D41, and E41 in FIG. 22 respectively, and A42, B42, C42, D42, and E42 in FIG. Each follows A42, B42, C42, D42, and E42 of FIG. Here, the difference between FIGS. 21, 22 and 23 and FIGS. 17, 18 and 19 is that the controller for determining the representative sensing device in tenant units is not the centralized controller 9 but the individual remote controller 8.
　なお、図２１，２２，２３における制御シーケンスは、空調システム内で複数台の空調装置１１が外気低温時の間欠運転制御を行う場合に、テナント単位で、最後に外気低温時の間欠運転制御を開始した空調装置１１が代表センシング装置となり、この代表センシング装置が間欠運転制御を終了するまでは、間欠運転制御状態が「実施中」である他の空調装置１１が給気用送風機を常時停止とする状態を維持し、センシング運転を行わないことを示している。なお、ここでは、最後に外気低温時の間欠運転制御を開始した空調装置１１は、空調装置１１ｂ，空調装置１１ｄであり、他の空調装置１１は、空調装置１１ａ，空調装置１１ｃである。これは、代表センシング装置を判定するコントローラーは、複数台の空調装置を管理可能なコントローラーであればよく、ビル全体を管理する集中コントローラー９に限定されないことを意味する。 21, 22, and 23, when a plurality of air conditioners 11 perform intermittent operation control when the outside temperature is low in the air conditioning system, finally, intermittent operation control when the outside temperature is low is started for each tenant. The air conditioner 11 becomes a representative sensing device, and until this representative sensing device finishes the intermittent operation control, the other air conditioner 11 whose intermittent operation control state is “in progress” always stops the air supply fan. This indicates that the sensing operation is not performed. Here, the air conditioners 11 that finally started the intermittent operation control at the time of low temperature of the outside air are the air conditioners 11b and 11d, and the other air conditioners 11 are the air conditioners 11a and 11c. This means that the controller that determines the representative sensing device may be a controller that can manage a plurality of air conditioners, and is not limited to the centralized controller 9 that manages the entire building.
　以上説明した本実施の形態１にかかる空調システムは、複数台の空調装置を管理するコントローラーが、空調装置の間欠運転制御状態を管理し、複数台の空調装置が間欠運転制御を行っている場合には、間欠運転制御におけるセンシング運転を代表で行う代表センシング装置を決定し、代表センシング装置以外の空調装置は間欠運転制御におけるセンシング運転を行わないように制御される。このようにして、不要なセンシング運転を行わないため、消費電力を抑えることができる。 In the air conditioning system according to the first embodiment described above, the controller that manages the plurality of air conditioners manages the intermittent operation control state of the air conditioner, and the plurality of air conditioners perform the intermittent operation control. The representative sensing device that representatively performs the sensing operation in the intermittent operation control is determined, and the air conditioner other than the representative sensing device is controlled not to perform the sensing operation in the intermittent operation control. Thus, since unnecessary sensing operation is not performed, power consumption can be suppressed.
実施の形態２．
　本実施の形態２では、実施の形態１における外気高湿度時の間欠運転制御に代えて室内ＣＯ２濃度低下時の間欠運転制御を行い、集中コントローラー９が代表センシング装置を間欠運転制御の種類に応じて管理する。 Embodiment 2. FIG.
In the second embodiment, instead of the intermittent operation control at the time of high outdoor air in the first embodiment, the intermittent operation control is performed when the indoor CO 2 concentration is lowered, and the centralized controller 9 controls the representative sensing device according to the type of the intermittent operation control. to manage.
　図２４は、駆動制御装置２０の制御動作の一例を示すフローチャートである。図２４に示す制御動作では、間欠運転制御を行っており、排気用送風機２５の動作については説明を省略する。なお、実施の形態１と同一機能及び同一構成については同一の符号を用いて説明を省略し、実施の形態１と同様に動作するものについては説明を省略し、援用するものとする。 FIG. 24 is a flowchart showing an example of the control operation of the drive control device 20. In the control operation shown in FIG. 24, intermittent operation control is performed, and the description of the operation of the exhaust fan 25 is omitted. Note that the same reference numerals are used for the same functions and the same configurations as those in the first embodiment, and descriptions thereof are omitted, and those that operate in the same manner as in the first embodiment are omitted and used.
　図２４において、駆動制御装置２０が個別リモートコントローラー８からの運転信号又は集中コントローラー９からの運転操作情報を受信すると、制御フローが開始する。制御フローが開始すると、駆動制御装置２０は、給気用送風機２４を一定時間運転する（Ｓ４１）。ここでは一定時間は３分としている。次に、駆動制御装置２０は、室外温湿度センサー２６の室外温湿度検知値である検知温度Ｔｏａが第１の規定温度Ｔ１℃未満であるか否か判定する（Ｓ４２）。検知温度Ｔｏａが第１の規定温度Ｔ１℃未満である場合（Ｓ４２：Ｙｅｓ）には、図２４の端子Ｃから図２５のＳ１２０１へ進み、検知温度Ｔｏａが第１の規定温度Ｔ１℃未満でない場合（Ｓ４２：Ｎｏ）には、Ｓ１２３へ進む。 24, when the drive control device 20 receives an operation signal from the individual remote controller 8 or driving operation information from the centralized controller 9, the control flow starts. When the control flow is started, the drive control device 20 operates the air supply fan 24 for a predetermined time (S41). Here, the fixed time is 3 minutes. Next, the drive control device 20 determines whether or not the detected temperature Toa, which is the outdoor temperature / humidity detection value of the outdoor temperature / humidity sensor 26, is lower than the first specified temperature T1 ° C. (S42). When the detected temperature Toa is lower than the first specified temperature T1 ° C. (S42: Yes), the process proceeds from the terminal C in FIG. 24 to S1201 in FIG. 25, and the detected temperature Toa is not lower than the first specified temperature T1 ° C. In (S42: No), it progresses to S123.
　Ｓ４２でＮｏに分岐すると、駆動制御装置２０は、外気低温時の間欠運転制御状態を終了とし（Ｓ１２３）、集中コントローラー９に外気低温時の間欠運転制御状態情報を送信し（Ｓ１２４）、ＣＯ２濃度センサー２７の濃度検知値である検知濃度Ｃｏａが第１の規定濃度Ｃ１ｐｐｍ未満であるか否か判定する（Ｓ１２５）。検知濃度Ｃｏａが第１の規定濃度Ｃ１ｐｐｍ未満である場合（Ｓ１２５：Ｙｅｓ）には図２４の端子Ｄから図２６のＳ１２２１へ進み、検知濃度Ｃｏａが第１の規定濃度Ｃ１ｐｐｍ未満でない場合（Ｓ１２５：Ｎｏ）にはＳ１２６へ進む。 When branching to No in S42, the drive control device 20 ends the intermittent operation control state when the outside air is cold (S123), transmits the intermittent operation control state information when the outside temperature is low (S124), and the CO 2 concentration sensor. It is determined whether or not the detected density Coa which is the density detected value of 27 is less than the first specified density C1 ppm (S125). When the detected concentration Coa is less than the first specified concentration C1 ppm (S125: Yes), the process proceeds from the terminal D in FIG. 24 to S1221 in FIG. 26, and when the detected concentration Coa is not less than the first specified concentration C1ppm (S125: In No), it progresses to S126.
　Ｓ１２５でＮｏに分岐すると、駆動制御装置２０は、ＣＯ２濃度低下時の間欠運転制御状態を終了とし（Ｓ１２６）、集中コントローラー９に間欠運転制御状態情報を送信し（Ｓ１２７）、給気用送風機２４を常時運転とし（Ｓ４６）、Ｓ４２へ戻る。 When branching to No in S125, the drive control device 20 ends the intermittent operation control state when the CO 2 concentration decreases (S126), transmits intermittent operation control state information to the centralized controller 9 (S127), and the air supply fan 24 Is always operated (S46), and the process returns to S42.
　図２５は、駆動制御装置２０の外気低温時の間欠運転制御の一例を示すフローチャートである。外気低温時の間欠運転制御を開始すると、駆動制御装置２０は、外気低温時の間欠運転制御状態を「実施中」とし（Ｓ１２０１）、集中コントローラー９へ外気低温時の間欠運転制御状態情報を送信し（Ｓ１２０２）、室内ＣＯ２濃度低下時の間欠運転制御状態情報を終了とし（Ｓ１２０３）、集中コントローラー９へ室内ＣＯ２濃度低下時の間欠運転制御状態情報を送信し（Ｓ１２０４）、集中コントローラー９から送信される外気低温時のセンシング停止指令がオンであるか否かを判定する（Ｓ１２０５）。ここで、センシング停止指令がオンである場合（Ｓ１２０５：Ｙｅｓ）には、空調システム内のセンシング運転を他の空調装置１１が代表して行っていることを意味する。一方、センシング停止指令がオフである場合（Ｓ１２０５：Ｎｏ）には、空調システム内のセンシング運転を、この駆動制御装置２０を備える空調装置１１が代表して行っていることを意味する。 FIG. 25 is a flowchart illustrating an example of intermittent operation control when the drive control device 20 is at a low outside air temperature. When the intermittent operation control at the low temperature of the outside air is started, the drive control device 20 sets the intermittent operation control state at the low temperature of the outside air to “in execution” (S1201), and transmits the intermittent operation control state information at the low temperature of the outside air to the centralized controller 9 (S1202). ), The intermittent operation control state information when the indoor CO 2 concentration decreases is terminated (S1203), the intermittent operation control state information when the indoor CO 2 concentration decreases is transmitted to the centralized controller 9 (S1204), and the outside air transmitted from the centralized controller 9 It is determined whether or not the sensing stop command at low temperature is on (S1205). Here, when the sensing stop command is ON (S1205: Yes), it means that the other air conditioner 11 is representatively performing the sensing operation in the air conditioning system. On the other hand, when the sensing stop command is OFF (S1205: No), it means that the air conditioning apparatus 11 including the drive control apparatus 20 performs the sensing operation in the air conditioning system as a representative.
　外気低温時のセンシング停止指令がオンである場合（Ｓ１２０５：Ｙｅｓ）には、給気用送風機２４は常時停止とされ（Ｓ４０４）、Ｓ１２０５に戻る。すなわち、空調システム内の他の空調装置１１に外気低温時のセンシングを委ね、この駆動制御装置２０を備える空調装置１１は外気低温時の間欠運転制御を行わず、集中コントローラー９からの外気低温時のセンシング停止指令がオフになるのを待つ。 If the sensing stop command at the time of low outdoor temperature is on (S1205: Yes), the air supply fan 24 is always stopped (S404), and the process returns to S1205. In other words, the other air conditioners 11 in the air conditioning system are left to perform sensing when the outside temperature is low, and the air conditioner 11 including this drive control device 20 does not perform intermittent operation control when the outside temperature is low, but from the centralized controller 9 when the outside temperature is low. Wait for the sensing stop command to turn off.
　外気低温時のセンシング停止指令がオフである場合（Ｓ１２０５：Ｎｏ）には、駆動制御装置２０は、集中コントローラー９から送信される外気低温時のセンシング停止指令のオンオフ変化の有無を判定する（Ｓ１２０６）。外気低温時のセンシング停止指令のオンオフ変化ありの場合（Ｓ１２０６：Ｙｅｓ）には、空調システム内の他の空調装置１１において、外気低温時の間欠運転制御が終了し、空調システム全体で外気低温時の間欠運転制御状態が解除されたことを意味する。一方、外気低温時のセンシング停止指令のオンオフ変化なしの場合（Ｓ１２０６：Ｎｏ）には、センシング停止指令がオフ状態を継続していれば、この駆動制御装置２０を備える空調装置１１が、空調システム内で最初に間欠運転制御を開始することを意味する。 When the sensing stop command at the time when the outside temperature is low is OFF (S1205: No), the drive control device 20 determines whether or not the sensing stop command at the time when the outside temperature is low is transmitted from the centralized controller 9 (S1206). ). When there is a change in the sensing stop command when the outside temperature is low (S1206: Yes), in the other air conditioners 11 in the air conditioning system, the intermittent operation control when the outside temperature is low ends, and the entire air conditioning system is intermittent when the outside temperature is low. This means that the operation control state has been released. On the other hand, in the case where there is no change in on / off of the sensing stop command when the outside temperature is low (S1206: No), if the sensing stop command continues in the off state, the air conditioner 11 including the drive control device 20 is This means that intermittent operation control is started first.
　外気低温時のセンシング停止指令のオンオフ変化なしの場合（Ｓ１２０６：Ｎｏ）には、給気用送風機２４をＴａ分間だけ停止させ、Ｔｂ分間だけ運転させる間欠運転制御を行い（Ｓ４０６）、外気低温時の間欠運転制御が終了したか否か判定する（Ｓ１２０７）。外気低温時の間欠運転制御が終了していない場合（Ｓ１２０７：Ｎｏ）には、Ｓ１２０５へ戻る。外気低温時の間欠運転制御が終了している場合（Ｓ１２０７：Ｙｅｓ）には、Ｓ４２へ戻る。 When there is no change in the on / off state of the sensing stop command when the outside temperature is low (S1206: No), intermittent operation control is performed in which the supply fan 24 is stopped for Ta minutes and operated for Tb (S406). It is determined whether or not the missing operation control is finished (S1207). When the intermittent operation control at the time of low outdoor temperature is not completed (S1207: No), the process returns to S1205. When the intermittent operation control at the time of low outdoor temperature has been completed (S1207: Yes), the process returns to S42.
　外気低温時のセンシング停止指令のオンオフ変化ありの場合（Ｓ１２０６：Ｙｅｓ）には、外気低温時の間欠運転制御状態は終了とし（Ｓ１２０８）、給気用送風機２４をＴｂ分間運転し（Ｓ４０９）、Ｓ４２へ戻る。 When the sensing stop command is turned on and off when the outside temperature is low (S1206: Yes), the intermittent operation control state when the outside temperature is low is terminated (S1208), the supply fan 24 is operated for Tb (S409), and S42. Return to.
　図２６は、駆動制御装置２０の室内ＣＯ２濃度低下時の間欠運転制御の一例を示すフローチャートである。なお、図２６に示すＳ１２２１からＳ１２２９までは、室内ＣＯ２濃度が低下したことにより換気不要と判断し、省エネ性を向上させるために行う動作である。駆動制御装置２０は、室内ＣＯ２濃度低下時の間欠運転制御状態を「実施中」とし（Ｓ１２２１）、集中コントローラー９へ室内ＣＯ２濃度低下時の間欠運転制御状態情報を送信し（Ｓ１２２２）、集中コントローラー９から送信される室内ＣＯ２濃度低下時のセンシング停止指令のオンオフを判定する（Ｓ１２２３）。ここで、センシング停止指令がオンである場合（Ｓ１２２３：Ｙｅｓ）には、空調システム内の室内ＣＯ２濃度低下時のセンシング運転を他の空調装置１１が代表して行っていることを意味する。一方、センシング停止指令がオフである場合（Ｓ１２２３：Ｎｏ）には、空調システム内の室内ＣＯ２濃度低下時のセンシング運転を、この駆動制御装置２０を備える空調装置１１が代表して行っていることを意味する。 FIG. 26 is a flowchart illustrating an example of intermittent operation control when the indoor CO 2 concentration of the drive control device 20 is reduced. Note that the S1221 of FIG. 26 to S1229, it is determined that the required ventilation by indoor CO 2 concentration decreases, an operation performed in order to improve energy efficiency. The drive control device 20 sets the intermittent operation control state when the indoor CO 2 concentration is reduced to “being executed” (S1221), and transmits the intermittent operation control state information when the indoor CO 2 concentration is reduced to the centralized controller 9 (S1222). 9 determines whether or not the sensing stop command is transmitted when the indoor CO 2 concentration decreases transmitted from 9 (S1223). Here, if the sensing stop command is ON: The (S1223 Yes), it means that the sensing operation of the indoor CO 2 concentration at a decline in the air conditioning system other air conditioner 11 is performed by a representative. On the other hand, the sensing stop command if is off: in (S1223 No), the sensing operation of the indoor CO 2 concentration at a decline in the air conditioning system, air conditioning system 11 provided with the drive control device 20 is performed by a representative Means that.
　室内ＣＯ２濃度低下時のセンシング停止指令がオンである場合（Ｓ１２２３：Ｙｅｓ）には、駆動制御装置２０は、給気用送風機２４を常時停止とし（Ｓ１２２４）、Ｓ１２２３に戻る。すなわち、空調システム内の他の空調装置１１に室内ＣＯ２濃度低下時のセンシングを委ね、この駆動制御装置２０を備える空調装置１１は室内ＣＯ２濃度低下時の間欠運転制御を行わず、集中コントローラー９からの室内ＣＯ２濃度低下時のセンシング停止指令がオフになるのを待つ。 If the sensing stop command when the indoor CO 2 concentration is reduced is on (S1223: Yes), the drive control device 20 always stops the air supply fan 24 (S1224), and returns to S1223. That is, sensing when the indoor CO 2 concentration is reduced is entrusted to other air conditioners 11 in the air conditioning system, and the air conditioner 11 including the drive control device 20 does not perform intermittent operation control when the indoor CO 2 concentration is reduced, and the centralized controller 9 Wait until the sensing stop command is turned off when the indoor CO 2 concentration decreases.
　室内ＣＯ２濃度低下時のセンシング停止指令がオフである場合（Ｓ１２２３：Ｎｏ）には、駆動制御装置２０は、集中コントローラー９から送信される室内ＣＯ２濃度低下時のセンシング停止指令のオンオフ変化の有無を判定する（Ｓ１２２５）。室内ＣＯ２濃度低下時のセンシング停止指令のオンオフ変化ありの場合（Ｓ１２２５：Ｙｅｓ）には、空調システム内の他の空調装置１１において、室内ＣＯ２濃度低下時の間欠運転制御が終了し、空調システム全体で室内ＣＯ２濃度低下時の間欠運転制御状態が解除されたことを意味する。一方、室内ＣＯ２濃度低下時のセンシング停止指令のオンオフ変化なしの場合（Ｓ１２２５：Ｎｏ）には、センシング停止指令がオフ状態を継続していれば、この駆動制御装置２０を備える空調装置１１が、空調システム内で最初に室内ＣＯ２濃度低下時の間欠運転制御を開始することを意味する。 When the sensing stop command when the indoor CO 2 concentration decreases is off (S1223: No), the drive control device 20 changes the on / off change of the sensing stop command when the indoor CO 2 concentration decreases transmitted from the centralized controller 9. The presence or absence is determined (S1225). In the case where there is an on / off change in the sensing stop command when the indoor CO 2 concentration decreases (S1225: Yes), the intermittent operation control when the indoor CO 2 concentration decreases is terminated in the other air conditioners 11 in the air conditioning system, and the air conditioning system It means that the intermittent operation control state when the indoor CO 2 concentration is reduced as a whole is released. On the other hand, if there is no on / off change in the sensing stop command when the indoor CO 2 concentration is reduced (S1225: No), if the sensing stop command continues in the off state, the air conditioner 11 including this drive control device 20 This means that the intermittent operation control when the indoor CO 2 concentration is reduced first is started in the air conditioning system.
　室内ＣＯ２濃度低下時のセンシング停止指令のオンオフ変化ありの場合（Ｓ１２２５：Ｙｅｓ）には、室内ＣＯ２濃度低下時の間欠運転制御状態は終了とし（Ｓ１２２８）、給気用送風機２４をＴｆ分間運転する（Ｓ１２２９）。なお、Ｓ１２２９は、ＣＯ２濃度センサー２７の濃度検知値の安定が目的であり、設置環境によってこのＴｆ分間は調整され、濃度検知値が待ち時間なく安定するのであれば、Ｔｆ＝０としてもよい。 If there is an on / off change in the sensing stop command when the indoor CO 2 concentration is reduced (S1225: Yes), the intermittent operation control state when the indoor CO 2 concentration is reduced is terminated (S1228), and the air supply fan 24 is operated for Tf. (S1229). Note that S1229 is for the purpose of stabilizing the concentration detection value of the CO 2 concentration sensor 27, and is adjusted for this Tf minutes depending on the installation environment. If the concentration detection value is stable without waiting time, Tf = 0 may be set. .
　室内ＣＯ２濃度低下時のセンシング停止指令のオンオフ変化なしの場合（Ｓ１２２５：Ｎｏ）には、給気用送風機２４をＴｅ分間だけ停止させ、Ｔｆ分間だけ運転させる室内ＣＯ２濃度低下時の間欠運転制御を行い（Ｓ１２２６）、室内ＣＯ２濃度低下時の間欠運転制御が終了したか否か判定する（Ｓ１２２７）。ここで、Ｔｆ分間の運転は、室内ＣＯ２濃度を検知するセンシング運転である。 If no on-off change of the sensing stop command at room CO 2 concentration decreased (S1225: No), the supply of air blower 24 only Te minutes stopped, intermittent operation control at the time of lowering the indoor CO 2 concentration be operated by Tf min Is performed (S1226), and it is determined whether or not the intermittent operation control when the indoor CO 2 concentration is reduced is completed (S1227). Here, the operation for Tf is a sensing operation for detecting the indoor CO 2 concentration.
　なお、ここでは、Ｃ１＝６００ｐｐｍ、Ｔｅ＝３０分、Ｔｆ＝５分とするが、本発明はこれに限定されるものではない。室内ＣＯ２濃度低下時の間欠運転制御が終了していない場合（Ｓ１２２７：Ｎｏ）には、Ｓ１２２３へ戻る。室内ＣＯ２濃度低下時の間欠運転制御が終了している場合（Ｓ１２２７：Ｙｅｓ）には、Ｓ４２へ戻る。 Here, C1 = 600 ppm, Te = 30 minutes, and Tf = 5 minutes, but the present invention is not limited to this. If the intermittent operation control when the indoor CO 2 concentration is decreased is not completed (S1227: No), the process returns to S1223. When the intermittent operation control when the indoor CO 2 concentration is reduced is completed (S1227: Yes), the process returns to S42.
　また、室内ＣＯ２濃度は、排気用送風機２５を運転することで検知することができる。そのため、排気用送風機２５は、給気用送風機２４の運転に連動させてもよいし、間欠運転としてもよい。 Further, the indoor CO 2 concentration can be detected by operating the exhaust fan 25. Therefore, the exhaust fan 25 may be linked to the operation of the air supply fan 24 or may be intermittently operated.
　また、室内ＣＯ２濃度が急激に上昇した場合に即座に換気可能とするために、間欠運転時には給気用送風機２４を停止させず、Ｔｅ分間の停止に代えて弱運転を行い、Ｔｆ分間の運転に代えて強運転を行い、風量の強弱を周期的に変更するように制御してもよい。 In addition, in order to allow immediate ventilation when the indoor CO 2 concentration suddenly increases, the air supply fan 24 is not stopped during intermittent operation, but instead of stopping for Te minutes, weak operation is performed, and Tf minutes Instead of driving, strong driving may be performed, and control may be performed so as to periodically change the strength of the air volume.
　図２７，２８は、集中コントローラー９の制御動作の一例を示すフローチャートである。図２７，２８において、集中コントローラー９の電源がオンされると、集中コントローラー９は、外気低温時の代表センシング装置を「なし」とし、室内ＣＯ２濃度低下時の代表センシング装置を「なし」として初期化する（Ｓ１３０１）。次に、集中コントローラー９は、外気低温時の代表センシング装置ではない空調装置１１から外気低温時の間欠運転制御状態が「実施中」との通知があるか否か判定する（Ｓ１３０２）。この外気低温時の間欠運転制御状態が「実施中」との通知は、Ｓ１２０２にて送信されたものである。外気低温時の間欠運転制御状態が「実施中」との通知がある場合（Ｓ１３０２：Ｙｅｓ）には、集中コントローラー９は、外気低温時の代表センシング装置があるか否か判定する（Ｓ１３０３）。外気低温時の代表センシング装置がある場合（Ｓ１３０３：Ｙｅｓ）には、集中コントローラー９は、外気低温時のセンシング停止指令をオンする送信を行い、すなわち外気低温時の代表センシング装置に外気低温時のセンシングを停止する指令を送信し（Ｓ１３０４）、外気低温時の代表センシング装置がＳ１３０２で通知した装置となるよう更新する（Ｓ１３０５）。外気低温時の代表センシング装置がない場合（Ｓ１３０３：Ｎｏ）には、集中コントローラー９は、センシング停止指令を送信することなく外気低温時の代表センシング装置がＳ１３０２で通知した装置となるよう更新する（Ｓ１３０５）。すなわち、集中コントローラー９は、外気低温時の代表センシング装置が、最後に外気低温時の間欠運転制御を開始した空調装置となるよう設定する。これにより、先に外気低温時の間欠運転制御を行っていた空調装置に対して外気低温時のセンシング運転を開始させず、不要なセンシング運転の回避により消費電力を抑えることができる。 27 and 28 are flowcharts showing an example of the control operation of the centralized controller 9. 27 and 28, when the power of the centralized controller 9 is turned on, the centralized controller 9 sets “None” as the representative sensing device when the outside air temperature is low, and sets “None” as the representative sensing device when the indoor CO 2 concentration decreases. Initialization is performed (S1301). Next, the centralized controller 9 determines whether or not there is a notification from the air conditioner 11 that is not a representative sensing device when the outside temperature is low that the intermittent operation control state when the outside temperature is low is “in progress” (S1302). The notification that the intermittent operation control state at the time when the outside air is low is “in progress” is transmitted in S1202. When there is a notification that the intermittent operation control state at the time when the outside temperature is low (S1302: Yes), the centralized controller 9 determines whether there is a representative sensing device when the outside temperature is low (S1303). When there is a representative sensing device when the outside air is cold (S1303: Yes), the centralized controller 9 transmits to turn on a sensing stop command when the outside temperature is low, that is, the representative sensing device when the outside temperature is low. A command to stop sensing is transmitted (S1304), and the representative sensing device at the time of low outside temperature is updated to be the device notified in S1302 (S1305). When there is no representative sensing device when the outside air is cold (S1303: No), the centralized controller 9 updates the representative sensing device when the outside temperature is low to be the device notified in S1302 without transmitting a sensing stop command ( S1305). That is, the centralized controller 9 sets the representative sensing device at the time of low outside air temperature to be the air conditioner that finally started the intermittent operation control at the low temperature of outside air. Thereby, it is possible to suppress power consumption by avoiding unnecessary sensing operation without starting the sensing operation at the low temperature of the outside air with respect to the air-conditioning apparatus that has previously performed the intermittent operation control at the low temperature of the outside air.
　なお、外気低温時の間欠運転制御状態が「実施中」である空調装置１１が増えることは、外気低温時のセンシング停止指令がオンであることを送信する空調装置１１が増えること、及び外気低温時の代表センシング装置が外気低温時の間欠運転制御を終了する場合に集中コントローラー９から外気低温時のセンシング停止指令がオフであることを通知する空調装置１１が増えることを意味する。 The increase in the number of air conditioners 11 in which the intermittent operation control state at the time when the outside air is low is “being executed” means that the number of air conditioners 11 that transmit that the sensing stop command is ON when the outside temperature is low, and the time when the outside temperature is low. This means that when the representative sensing device ends the intermittent operation control when the outside temperature is low, the number of air conditioners 11 that notifies the centralized controller 9 that the sensing stop command when the outside temperature is low is off increases.
　外気低温時の間欠運転制御状態が「実施中」との通知がない場合（Ｓ１３０２：Ｎｏ）にも、集中コントローラー９は、外気低温時の代表センシング装置があるか否か判定する（Ｓ１３０６）。外気低温時の代表センシング装置がある場合（Ｓ１３０６：Ｙｅｓ）には、集中コントローラー９は、外気低温時の代表センシング装置である空調装置１１から外気低温時の間欠運転制御状態情報が終了したとの通知がなされたか否か判定する（Ｓ１３０７）。外気低温時の代表センシング装置である空調装置１１から外気低温時の間欠運転制御状態情報が終了したとの通知がある場合（Ｓ１３０７：Ｙｅｓ）には、外気低温時のセンシング停止指令オンを送信したすべての空調装置１１に対して外気低温時のセンシング停止指令をオフするよう送信し（Ｓ１３０８）、外気低温時の代表センシング装置を「なし」として初期化する（Ｓ１３０９）。また、外気低温時の代表センシング装置がない場合（Ｓ１３０６：Ｎｏ）又は外気低温時の代表センシング装置である空調装置１１から外気低温時の間欠運転制御状態が終了したとの通知がない場合（Ｓ１３０７：Ｎｏ）にはＳ１３１２へ進む。なお、外気低温時の代表センシング装置がＳ１３０２で通知した装置となるよう更新し（Ｓ１３０５）、又は外気低温時の代表センシング装置を「なし」として初期化した（Ｓ１３０９）後も同様である。 Even when there is no notification that the intermittent operation control state at the time when the outside air is cold (S1302: No), the centralized controller 9 determines whether there is a representative sensing device when the outside temperature is low (S1306). When there is a representative sensing device when the outside temperature is low (S1306: Yes), the centralized controller 9 notifies that the intermittent operation control state information when the outside temperature is low is finished from the air conditioner 11 which is a representative sensing device when the outside temperature is low. It is determined whether or not has been made (S1307). When there is a notification from the air conditioner 11 that is a representative sensing device when the outside temperature is low that the intermittent operation control state information when the outside temperature is low (S1307: Yes), all of the sensing stop command on when the outside temperature is low are all transmitted Is sent to the air conditioner 11 to turn off the sensing stop command when the outside temperature is low (S1308), and the representative sensing device when the outside temperature is low is initialized as “none” (S1309). Further, when there is no representative sensing device when the outside temperature is low (S1306: No), or when there is no notification from the air conditioner 11 which is the representative sensing device when the outside temperature is low that the intermittent operation control state when the outside temperature is low (S1307: In No), it progresses to S1312. The same applies after updating the representative sensing device at the time of low outside temperature to be the device notified at S1302 (S1305) or initializing the representative sensing device at the low temperature of outside air as “none” (S1309).
　次に、図２７の端子Ｅから図２８のＳ１３１２へと進み、集中コントローラー９は、室内ＣＯ２濃度低下時の代表センシング装置ではない空調装置１１から室内ＣＯ２濃度低下時の間欠運転制御状態が「実施中」との通知がなされたか否か判定する（Ｓ１３１２）。この室内ＣＯ２濃度低下時の間欠運転制御状態が「実施中」との通知は、Ｓ１２２２にて送信されたものである。室内ＣＯ２濃度低下時の間欠運転制御状態が「実施中」との通知があった場合（Ｓ１３１２：Ｙｅｓ）には、集中コントローラー９は、室内ＣＯ２濃度低下時の代表センシング装置があるか否か判定する（Ｓ１３１３）。室内ＣＯ２濃度低下時の代表センシング装置がある場合（Ｓ１３１３：Ｙｅｓ）には、集中コントローラー９は、室内ＣＯ２濃度低下時のセンシング停止指令をオンする送信を行い、室内ＣＯ２濃度低下時の代表センシング装置に室内ＣＯ２濃度低下時のセンシングを停止する指令を送信し（Ｓ１３１４）、室内ＣＯ２濃度低下時の代表センシング装置がＳ１３１２で通知した装置となるよう更新する（Ｓ１３１５）。室内ＣＯ２濃度低下時の代表センシング装置がない場合（Ｓ１３１３：Ｎｏ）には、集中コントローラー９は、センシング停止指令を送信することなく室内ＣＯ２濃度低下時の代表センシング装置がＳ１３１２で通知した装置となるよう更新する（Ｓ１３１５）。すなわち、集中コントローラー９は、室内ＣＯ２濃度低下時の代表センシング装置が、最後に室内ＣＯ２濃度低下時の間欠運転制御を開始した空調装置となるよう設定する。これにより、先に室内ＣＯ２濃度低下時の間欠運転制御を行っていた空調装置に対して室内ＣＯ２濃度低下時のセンシング運転を開始させず、不要なセンシング運転の回避により消費電力を抑えることができる。 Then, the process proceeds to S1312 of FIG. 28 from the terminal E in FIG. 27, the centralized controller 9, the air conditioner 11 is not a typical sensing device when the indoor CO 2 concentration decreases the intermittent operation control state in the indoor CO 2 concentration decreases " It is determined whether or not a notification “in progress” has been made (S1312). The notification that the intermittent operation control state when the indoor CO 2 concentration is reduced is “in progress” is transmitted in S1222. When there is a notification that the intermittent operation control state when the indoor CO 2 concentration decreases is “in progress” (S1312: Yes), the centralized controller 9 determines whether there is a representative sensing device when the indoor CO 2 concentration decreases. Determination is made (S1313). If there is a representative sensing device when the indoor CO 2 concentration decreased (S1313: Yes), the centralized controller 9 performs the transmission of turning on the sensing stop command at room CO 2 concentration decreases, when the indoor CO 2 concentration decreases A command to stop sensing when the indoor CO 2 concentration is reduced is transmitted to the representative sensing device (S1314), and the representative sensing device when the indoor CO 2 concentration is reduced is updated to be the device notified in S1312 (S1315). When there is no representative sensing device when the indoor CO 2 concentration is reduced (S1313: No), the centralized controller 9 is the device notified by the representative sensing device when the indoor CO 2 concentration is reduced in S1312 without transmitting a sensing stop command. (S1315). That is, centralized controller 9, a representative sensing device when the indoor CO 2 concentration decreases, set to be the last air-conditioning system has started intermittent operation control at the time of the indoor CO 2 concentration decreases. Thus, previously without starting the sensing operation during indoor CO 2 concentration decreases relative to the air-conditioning apparatus which has been subjected to the intermittent operation control at the time of the indoor CO 2 concentration decreases, it is possible to suppress the power consumption by avoiding unnecessary sensing operation it can.
　なお、室内ＣＯ２濃度低下時の間欠運転制御状態が「実施中」である空調装置１１が増えることは、室内ＣＯ２濃度低下時のセンシング停止指令がオンであることを送信する空調装置１１が増えること、及び室内ＣＯ２濃度低下時の代表センシング装置が室内ＣＯ２濃度低下時の間欠運転制御を終了する場合に集中コントローラー９から室内ＣＯ２濃度低下時のセンシング停止指令がオフであることを通知する空調装置１１が増えることを意味する。 An increase in the number of air conditioners 11 in which the intermittent operation control state when the indoor CO 2 concentration is reduced is “in progress” means that the number of air conditioners 11 that transmit that the sensing stop command is ON when the indoor CO 2 concentration is reduced increases. it, and the indoor CO 2 concentration representatives sensing device when lowering notifies the sensing stop command of the indoor CO 2 concentration at reduced from the central controller 9 to terminate the intermittent operation control at the time of the indoor CO 2 concentration decreases is off It means that the air conditioner 11 increases.
　室内ＣＯ２濃度低下時の間欠運転制御状態が「実施中」との通知がない場合（Ｓ１３１２：Ｎｏ）にも、集中コントローラー９は、室内ＣＯ２濃度低下時の代表センシング装置があるか否か判定する（Ｓ１３１６）。室内ＣＯ２濃度低下時の代表センシング装置がある場合（Ｓ１３１６：Ｙｅｓ）には、集中コントローラー９は、室内ＣＯ２濃度低下時の代表センシング装置である空調装置１１から室内ＣＯ２濃度低下時の間欠運転制御状態が終了したとの通知がなされたか否か判定する（Ｓ１３１７）。室内ＣＯ２濃度低下時の代表センシング装置である空調装置１１から室内ＣＯ２濃度低下時の間欠運転制御状態が終了したとの通知がある場合（Ｓ１３１７：Ｙｅｓ）には、室内ＣＯ２濃度低下時のセンシング停止指令がオンであると送信したすべての空調装置１１に対して室内ＣＯ２濃度低下時のセンシング停止指令をオフする送信を行い、室内ＣＯ２濃度低下時のセンシング停止する指令を送信し（Ｓ１３１８）、室内ＣＯ２濃度低下時の代表センシング装置を「なし」として初期化する（Ｓ１３１９）。また、室内ＣＯ２濃度低下時の代表センシング装置がない場合（Ｓ１３１６：Ｎｏ）又は室内ＣＯ２濃度低下時の代表センシング装置である空調装置１１から室内ＣＯ２濃度低下時の間欠運転制御状態が終了したとの通知がない場合（Ｓ１３１７：Ｎｏ）には図２８の端子Ｆから図２７のＳ１３０２へ戻る。なお、室内ＣＯ２濃度低下時の代表センシング装置がＳ１３１２で通知した装置となるよう更新し（Ｓ１３１５）、又は室内ＣＯ２濃度低下時の代表センシング装置を「なし」として初期化した（Ｓ１３１９）後も同様である。 Even when there is no notification that the intermittent operation control state at the time when the indoor CO 2 concentration decreases is “in progress” (S1312: No), the centralized controller 9 determines whether there is a representative sensing device when the indoor CO 2 concentration decreases. (S1316). If there is a representative sensing device when the indoor CO 2 concentration decreases: in (S1316 Yes), the centralized controller 9, the intermittent operation when the indoor CO 2 concentration decreases from the air conditioner 11 is a representative sensing device when the indoor CO 2 concentration decreases It is determined whether or not a notification that the control state has ended has been made (S1317). If there is a notification from the air conditioning device 11 is a representative sensing device when the indoor CO 2 concentration decreases the intermittent operation control state in the indoor CO 2 concentration decreased ended (S1317: Yes), the at indoor CO 2 concentration decreases A transmission to turn off the sensing stop command when the indoor CO 2 concentration decreases is sent to all the air conditioners 11 that have transmitted that the sensing stop command is on, and a command to stop sensing when the indoor CO 2 concentration decreases ( In step S1318, the representative sensing device when the indoor CO 2 concentration decreases is initialized as “none” (S1319). If there is no representative sensing device when the indoor CO 2 concentration decreased (S1316: No), or from the air-conditioning device 11 is a representative sensing device when the indoor CO 2 concentration decreases the intermittent operation control state in the indoor CO 2 concentration decreased ended (S1317: No), the process returns from the terminal F in FIG. 28 to S1302 in FIG. The representative sensing device when the indoor CO 2 concentration is lowered is updated to be the device notified in S1312 (S1315), or the representative sensing device when the indoor CO 2 concentration is lowered is initialized as “none” (S1319). Is the same.

　なお、図２９，３０，３１における制御シーケンスは、空調システム内で複数台の空調装置１１が外気低温時の間欠運転制御及び室内ＣＯ２濃度低下時の間欠運転制御を行う場合に、集中コントローラー９が外気低温時の代表センシング装置及び室内ＣＯ２濃度低下時の代表センシング装置を個別に管理し、最後に外気低温時の間欠運転制御を開始した空調装置１１ｂが外気低温時の代表センシング装置となり、この代表センシング装置が外気低温時の間欠運転制御を終了するまでは、外気低温時の間欠運転制御状態が「実施中」である他の空調装置１１ａが給気用送風機２４を常時停止とする状態を維持し、センシング運転を行わず、最後に室内ＣＯ２濃度低下時の間欠運転制御を開始した空調装置１１ｄが室内ＣＯ２濃度低下時の代表センシング装置となり、この代表センシング装置が室内ＣＯ２濃度低下時の間欠運転制御を終了するまでは、室内ＣＯ２濃度低下時の間欠運転制御状態が「実施中」である他の空調装置１１ｃが給気用送風機２４を常時停止とする状態を維持し、センシング運転を行わないことを示している。 29, 30, and 31, the control sequence in the air conditioning system is such that when the plurality of air conditioners 11 perform intermittent operation control when the outside air temperature is low and intermittent operation control when the indoor CO 2 concentration decreases, the central controller 9 The representative sensing device at low temperature and the representative sensing device at low indoor CO 2 concentration are individually managed, and finally the air conditioner 11b that started the intermittent operation control at low outside air temperature becomes the representative sensing device at low outside air temperature. Until the device finishes the intermittent operation control when the outside air is cold, the other air conditioner 11a in which the intermittent operation control state when the outside temperature is low is “practicing” maintains the state where the air supply fan 24 is always stopped, and sensing The air conditioner 11d that has started the intermittent operation control when the indoor CO 2 concentration is lowered lastly without performing the operation is a representative when the indoor CO 2 concentration is lowered. Becomes sensing device, the representative until sensing device terminates the intermittent operation control at the time of the indoor CO 2 concentration decreases, indoor CO 2 concentration other air conditioner 11c is a supply air intermittent operation control state is "during execution" during reduction The state where the blower 24 is always stopped is maintained, and the sensing operation is not performed.
　以上説明した本実施の形態２にかかる空調システムは、複数台の空調装置を管理するコントローラーが、空調装置の間欠運転制御状態を間欠運転制御の種類に応じて管理し、周期の異なる間欠運転制御が同時に発生した場合でも、適切に不要なセンシング運転を行わないようにする。このようにして、複数台の空調装置が、不要なセンシング運転を行わないため、消費電力を抑えることができる。 In the air conditioning system according to the second embodiment described above, the controller that manages a plurality of air conditioners manages the intermittent operation control state of the air conditioners according to the type of intermittent operation control, and intermittent operation control with different periods. Even if both occur simultaneously, avoid unnecessary sensing operation. Thus, since a plurality of air conditioners do not perform unnecessary sensing operation, power consumption can be suppressed.
　なお、Ｓ１２０３においては、外気低温時の間欠運転制御を開始する際の室内ＣＯ２濃度低下時の間欠運転制御状態を「終了」とした。これは、本実施の形態２においては、外気低温時の間欠運転制御と室内ＣＯ２濃度低下時の間欠運転制御との２つの間欠運転制御がいずれも給気用送風機に対して間欠運転制御を行うようにしたため、両制御が干渉しないようにした措置である。従って、複数種類の間欠運転制御の制御対象が給気用送風機２４と排気用送風機２５とで異なっている場合には、複数種類の間欠運転制御が干渉しないので、Ｓ１２０３，Ｓ１２０４を行わないように制御してもよい。 In S1203, the intermittent operation control state at the time when the indoor CO 2 concentration is reduced when the intermittent operation control at the low temperature of the outside air is started is “finished”. In the second embodiment, the two intermittent operation controls, that is, the intermittent operation control when the outside air is cold and the intermittent operation control when the indoor CO 2 concentration is reduced, both perform intermittent operation control on the air supply fan. This is a measure to prevent both controls from interfering with each other. Therefore, when the control targets of the plurality of types of intermittent operation control are different between the air supply fan 24 and the exhaust fan 25, the plurality of types of intermittent operation control do not interfere with each other, so that S1203 and S1204 are not performed. You may control.
　また、実施の形態１，２においては、換気機能を有する空調装置について説明したが本発明はこれに限定されるものではない。本発明の空調装置は加湿装置又は冷暖房装置であってもよい。空調装置が加湿装置である場合には、室内高湿度時の間欠運転制御を行い、複数台の加湿装置を管理するコントローラーが、同一室内にある加湿装置を代表センシング装置を判定するグループとすると、複数台の加湿装置が、不要なセンシング運転を行わず、消費電力を抑えることができる。すなわち、室内外の温度、湿度、ガス濃度といった環境情報を間欠運転制御によりセンシングする空調装置であれば、換気機能を有する空調装置に限定されるものではない。 In the first and second embodiments, the air conditioner having a ventilation function has been described, but the present invention is not limited to this. The air conditioner of the present invention may be a humidifier or an air conditioner. When the air conditioner is a humidifier, the controller that performs intermittent operation control at high humidity in the room and manages the plurality of humidifiers is a group that determines the representative sensing device for the humidifiers in the same room. The humidifier of the stand does not perform unnecessary sensing operation and can reduce power consumption. That is, as long as the air conditioner senses environmental information such as indoor and outdoor temperatures, humidity, and gas concentration by intermittent operation control, the air conditioner is not limited to an air conditioner having a ventilation function.
実施の形態３．
　実施の形態１においては最後に間欠運転制御を開始した空調装置を代表センシング装置としているが、本実施の形態３では最初に間欠運転制御を開始した空調装置を代表センシング装置とする形態について説明する。 Embodiment 3 FIG.
In the first embodiment, the air conditioning apparatus that finally started the intermittent operation control is used as the representative sensing device. In the third embodiment, the air conditioning apparatus that first started the intermittent operation control is used as the representative sensing device. .
　図３２は、駆動制御装置２０の制御動作の一例を示すフローチャートである。図３２に示す制御動作では、間欠運転制御を行っており、排気用送風機２５の動作については説明を省略する。なお、実施の形態１と同一機能及び同一構成については同一の符号を用いて説明を省略し、実施の形態１と同様に動作するものについては説明を省略し、援用するものとする。 FIG. 32 is a flowchart showing an example of the control operation of the drive control device 20. In the control operation shown in FIG. 32, intermittent operation control is performed, and the description of the operation of the exhaust fan 25 is omitted. Note that the same reference numerals are used for the same functions and the same configurations as those in the first embodiment, and descriptions thereof are omitted, and those that operate in the same manner as in the first embodiment are omitted and used.
　図３２では、図７におけるＳ５０４がＳ１５０４に変更され、図７におけるＳ５０４のセンシング停止指令の送信先がＳ５０２で通知した装置に変更されている。Ｓ１５０４においては、集中コントローラー９が、Ｓ５０２で間欠運転制御＝「実施中」を通知した空調装置１１へ、「センシング停止指令＝ＯＮ」を送信し、Ｓ５０２へ戻る。すなわち、空調システム内で最初に間欠運転制御が「実施中」であることを通知して代表センシング装置となった空調装置１１が、センシング運転を行い、後から間欠運転制御状態が「実施中」であることを通知した空調装置１１はセンシング運転を行わないことを意味する。 32, S504 in FIG. 7 is changed to S1504, and the transmission destination of the sensing stop command in S504 in FIG. 7 is changed to the apparatus notified in S502. In S1504, the centralized controller 9 transmits “Sensing stop command = ON” to the air conditioner 11 that has notified intermittent operation control = “in progress” in S502, and returns to S502. That is, the air conditioning apparatus 11 that first notifies that the intermittent operation control is “in progress” in the air conditioning system and becomes the representative sensing apparatus performs the sensing operation, and the intermittent operation control state is “under execution” later. This means that the air conditioner 11 that has notified that the sensing operation is not performed.
　図３３，３４，３５は、本発明の実施の形態３にかかる空調システムの制御シーケンスの一例を示す図である。図３３，３４，３５には、空調装置１１ａ，１１ｂ，１１ｒ，１１ｓが外気低温時の間欠運転制御を行う際の集中コントローラー９と空調装置１１ａ，１１ｂ，１１ｒ，１１ｓとの間の制御シーケンスを示している。図３３，３４，３５において、図３３のＡ６１，Ｂ６１，Ｃ６１，Ｄ６１，Ｅ６１は各々図３４のＡ６１，Ｂ６１，Ｃ６１，Ｄ６１，Ｅ６１に続き、図３４のＡ６２，Ｂ６２，Ｃ６２，Ｄ６２，Ｅ６２は各々図３５のＡ６２，Ｂ６２，Ｃ６２，Ｄ６２，Ｅ６２に続く。図３３，３４，３５に示す制御シーケンスでは、空調システム内で複数台の空調装置１１が外気低温時の間欠運転制御を行う場合に、最初に外気低温時の間欠運転制御を開始した空調装置１１ａが代表センシング装置となり、この代表センシング装置が間欠運転制御を終了するまでは、間欠運転制御状態が「実施中」である他の空調装置１１では、給気用送風機２４が常時停止の状態を維持し、センシング運転を行わないことを示している。 33, 34, and 35 are diagrams illustrating an example of a control sequence of the air conditioning system according to the third embodiment of the present invention. 33, 34, and 35 show a control sequence between the centralized controller 9 and the air conditioners 11a, 11b, 11r, and 11s when the air conditioners 11a, 11b, 11r, and 11s perform intermittent operation control when the outside temperature is low. ing. 33, 34, and 35, A61, B61, C61, D61, and E61 in FIG. 33 follow A61, B61, C61, D61, and E61 in FIG. 34, respectively, and A62, B62, C62, D62, and E62 in FIG. Each follows A62, B62, C62, D62, and E62 in FIG. In the control sequences shown in FIGS. 33, 34, and 35, when a plurality of air conditioners 11 perform intermittent operation control when the outside temperature is low in the air conditioning system, the air conditioner 11a that first started the intermittent operation control when the outside temperature is low is representative. Until the representative sensing device finishes the intermittent operation control, in the other air conditioner 11 in which the intermittent operation control state is “in progress”, the air supply fan 24 maintains a constantly stopped state, This indicates that sensing operation is not performed.
　以上説明した本実施の形態３にかかる空調システムは、間欠運転制御におけるセンシング運転を代表で行う代表センシング装置を最初に間欠運転制御を開始した空調装置に決定し、後に間欠運転制御を開始した空調装置のセンシング運転を行わないように制御しつつ、より早く間欠運転制御から復帰することができる。このようにして、複数台の空調装置が、不要なセンシング運転を行わないため、消費電力を抑えることができる。 The air conditioning system according to the third embodiment described above determines the representative sensing device that performs the sensing operation in the intermittent operation control as the representative air conditioning device that first started the intermittent operation control, and later started the intermittent operation control. While controlling so as not to perform the sensing operation of the device, it is possible to return from the intermittent operation control more quickly. Thus, since a plurality of air conditioners do not perform unnecessary sensing operation, power consumption can be suppressed.
　一例として、間欠運転制御が６０分間停止し、３分間運転するように制御する場合に、空調装置１１ａが最初に間欠運転制御を開始してから３０分後に空調装置１１ｂが間欠運転制御を開始した場合、実施の形態１では間欠運転制御を終了するまでに９０分かかるが、本実施の形態３では６０分で終了する。すなわち、空調装置１１ａは、より早く間欠運転制御から復帰することができる。 As an example, when intermittent operation control is stopped for 60 minutes and controlled to operate for 3 minutes, the air conditioner 11b starts intermittent operation control 30 minutes after the air conditioner 11a first starts intermittent operation control. In this case, it takes 90 minutes to end the intermittent operation control in the first embodiment, but in 60 minutes in the third embodiment. That is, the air conditioner 11a can return from the intermittent operation control earlier.
　なお、本実施の形態３においては、外気低温時の間欠運転制御を例示して説明したが、本発明はこれに限定されず、外気高湿度時の間欠運転制御、フロアー単位での外気低温時の間欠運転制御、テナント単位での間欠運転制御、室内ＣＯ２濃度低下時の間欠運転制御にも適用可能である。 In the third embodiment, the intermittent operation control at the low temperature of the outside air is exemplified and described. However, the present invention is not limited to this, and the intermittent operation control at the high temperature of the outside air and the intermittent operation at the low temperature of the outside air in units of floors. The present invention is also applicable to control, intermittent operation control in units of tenants, and intermittent operation control when the indoor CO 2 concentration decreases.
　以上の実施の形態１から３に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configurations shown in the above first to third embodiments show an example of the contents of the present invention, and can be combined with other known techniques, as long as they do not depart from the gist of the present invention. It is possible to omit or change a part of the configuration.
