It is realized by the circuit.
　本処理回路は、専用のハードウェアであっても、メモリ及びメモリに格納されるプログラムを実行するＣＰＵ（Central　Processing　Unit、中央演算装置）を備える制御回路であってもよい。ここでメモリとは、例えば、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、フラッシュメモリなどの、不揮発性または揮発性の半導体メモリなどが該当する。図２は、実施の形態の制御回路の構成例を示す図である。この制御回路は例えば、図２に示す構成の制御回路１００となる。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、ＡＳＩＣ（Application　Specific　Integrated　Circuit）、ＦＰＧＡ（Field　Programmable　Gate　Array）、またはこれらを組み合わせたものである。 This processing circuit may be dedicated hardware or a control circuit including a memory and a CPU (Central Processing Unit, central processing unit) that executes a program stored in the memory. Here, the memory corresponds to, for example, a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), and a flash memory. FIG. 2 is a diagram showing a configuration example of the control circuit of the embodiment. This control circuit is, for example, the control circuit 100 having the configuration shown in FIG. When the processing circuit is dedicated hardware, the processing circuit is, for example, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.
　図２に示すように、制御回路１００は、ＣＰＵであるプロセッサ１００ａと、メモリ１００ｂとを備える。図２に示す制御回路１００により実現される場合、プロセッサ１００ａがメモリ１００ｂに記憶された、各処理に対応するプログラムを読みだして実行することにより実現される。また、メモリ１００ｂは、プロセッサ１００ａが実施する各処理における一時メモリとしても使用される。記憶部２５は、メモリ１００ｂで構成される。 As shown in FIG. 2, the control circuit 100 includes a processor 100a, which is a CPU, and a memory 100b.

The memory 100b is also used as a temporary memory in each process performed by the processor 100a. The storage unit 25 is composed of a memory 100b.
　室外機２０の動作について説明する。図３は、実施の形態にかかる室外機２０の動作の流れを示すフローチャートである。空気調和機１０の電源が入ると、室外機２０の電源が入る（ステップＳ１）。室外機２０の電源が入ると、第１の運転制御部２１は記憶部２５から、第１のアクチュエータ装置２２の運転の制御に用いる運転情報を取得する（ステップＳ２）。第１の運転制御部２１が運転情報を取得しているとき、第１のアクチュエータ装置２２は停止中である（ステップＳ３）。運転情報には第１の運転制御部２１で収集された温度の情報、第２の運転制御部３１で収集された室内の温度情報、設定温度の情報、運転モードの情報が含まれる。 The operation of the outdoor unit 20 will be described. FIG. 3 is a flowchart showing an operation flow of the outdoor unit 20 according to the embodiment. When the power of the air conditioner 10 is turned on, the power of the outdoor unit 20 is turned on (step S1). When the power of the outdoor unit 20 is turned on, the first operation control unit 21 acquires the operation information used for controlling the operation of the first actuator device 22 from the storage unit 25 (step S2). When the first operation control unit 21 is acquiring the operation information, the first actuator device 22 is stopped (step S3). The operation information includes temperature information collected by the first operation control unit 21, indoor temperature information collected by the second operation control unit 31, set temperature information, and operation mode information.
　第１のアクチュエータ装置２２の停止中、第１の運転制御部２１は、通信線５０を介して操作装置４０から運転情報とは異なる、運転を開始させる情報を受信したかを確認し、かつ通信線５０の異常が確定していないか確認する（ステップＳ４）。通信線５０を介して操作装置４０から運転を開始させる情報を受信し、かつ通信線５０の異常が確定していない場合（ステップＳ４，Ｙｅｓ）、第１の運転制御部２１は、第１のアクチュエータ装置２２を動作させる（ステップＳ５）。通信線５０を介して操作装置４０から運転を開始させる情報を受信しない場合または、通信線５０の異常が確定している場合（ステップＳ４，Ｎｏ）、第１の運転制御部２１は、第１のアクチュエータ装置２２を動作させず処理を完了する。通信線５０の異常が確定している場合とは、例えば、ステップＳ１で空気調和機１０の電源が入る前に、空気調和機１０が動作しており、このときに通信線５０の異常が確認されこの異常が正常になっていない状態のまま空気調和機１０の電源が切られた場合が挙げられる。 While the first actuator device 22 is stopped, the first operation control unit 21 confirms whether or not it has received information for starting operation, which is different from the operation information, from the operation device 40 via the communication line 50, and communicates. It is confirmed whether or not the abnormality of the line 50 is confirmed (step S4). When the information for starting the operation is received from the operation device 40 via the communication line 50 and the abnormality of the communication line 50 is not confirmed (step S4, Yes), the first operation control unit 21 is the first. The actuator device 22 is operated (step S5). When the information for starting the operation is not received from the operation device 40 via the communication line 50, or when the abnormality of the communication line 50 is confirmed (steps S4 and No), the first operation control unit 21 is the first. The processing is completed without operating the actuator device 22 of the above. When the abnormality of the communication line 50 is confirmed, for example, the air conditioner 10 is operating before the power of the air conditioner 10 is turned on in step S1, and the abnormality of the communication line 50 is confirmed at this time. There is a case where the power of the air conditioner 10 is turned off while this abnormality is not normal.
　第１のアクチュエータ装置２２の動作中においても、第１の運転制御部２１は、第１の温度検出部２４で検出された温度情報を収集する（ステップＳ６）。また、第１の運転制御部２１は、運転情報を収集する（ステップＳ７）。第１の運転制御部２１は、収集した温度情報および運転情報をあらかじめ定められた周期で、記憶部２５に出力する。記憶部２５は、温度情報および運転情報を保存する（ステップＳ８）。記憶部２５に保存した情報は、通信線５０に異常が発生したときに室外機２０が行う代用値運転を実施するときに使用される。代用値運転の詳細については後述する。 Even during the operation of the first actuator device 22, the first operation control unit 21 collects the temperature information detected by the first temperature detection unit 24 (step S6). In addition, the first operation control unit 21 collects operation information (step S7). The first operation control unit 21 outputs the collected temperature information and operation information to the storage unit 25 at a predetermined cycle. The storage unit 25 stores the temperature information and the operation information (step S8). The information stored in the storage unit 25 is used when performing the substitute value operation performed by the outdoor unit 20 when an abnormality occurs in the communication line 50. The details of the substitute value operation will be described later.
　第１の運転制御部２１は、第１のアクチュエータ装置２２の動作中に、操作装置４０から運転を停止させる情報を受信した、または通信線５０に通信異常が発生し、通信異常が発生したことが確定したか確認する（ステップＳ９）。第１のアクチュエータ装置２２の動作中に、操作装置４０から運転を停止させる情報を受信した、または通信線５０に通信異常が発生し、通信異常が発生したことが確定した場合（ステップＳ９，Ｙｅｓ）、第１の運転制御部２１は第１のアクチュエータ装置２２を停止させる（ステップＳ１０）。第１のアクチュエータ装置２２の動作中に、操作装置４０から運転を停止させる情報を受信していない、または通信線５０に通信異常が発生し、通信異常が発生したことが確定していない場合（ステップＳ９，Ｎｏ）、第１の運転制御部２１は、通常の運転を行う。また、処理はステップＳ６に戻る。ステップＳ９の通信異常が発生したことが確定した場合とは、例えば、通信異常の状態があらかじめ定められた時間以上続いた場合が挙げられる。室外機２０の通常の運転のときは、第１の運転制御部２１は、第２の運転制御部３１が送信する室内機３０の温度情報、室外機２０の温度情報、および設定温度を用いて第１のアクチュエータ装置２２を制御する。具体的には、例えば、運転モードが暖房である場合、第１の運転制御部２１は、室内機３０の温度情報よりも設定温度の方が高いとき、圧縮機を駆動させる。また、例えば、圧縮機の温度があらかじめ定められた温度よりも高い場合、第１の運転制御部２１は、第１のファンを圧縮機の温度があらかじめ定められた温度よりも低い場合にくらべて速く回転させる。 The first operation control unit 21 received information to stop the operation from the operation device 40 during the operation of the first actuator device 22, or a communication abnormality occurred on the communication line 50, and a communication abnormality occurred. Is confirmed (step S9). When information for stopping the operation is received from the operating device 40 during the operation of the first actuator device 22, or a communication error occurs on the communication line 50 and it is confirmed that the communication error has occurred (steps S9, Yes). ), The first operation control unit 21 stops the first actuator device 22 (step S10). When the information for stopping the operation is not received from the operating device 40 during the operation of the first actuator device 22, or when a communication error occurs on the communication line 50 and it is not confirmed that the communication error has occurred ( Steps S9, No), the first operation control unit 21 performs normal operation. Further, the process returns to step S6. The case where it is confirmed that the communication abnormality has occurred in step S9 is, for example, the case where the state of the communication abnormality continues for a predetermined time or longer. During normal operation of the outdoor unit 20, the first operation control unit 21 uses the temperature information of the indoor unit 30, the temperature information of the outdoor unit 20, and the set temperature transmitted by the second operation control unit 31. It controls the first actuator device 22. Specifically, for example, when the operation mode is heating, the first operation control unit 21 drives the compressor when the set temperature is higher than the temperature information of the indoor unit 30. Further, for example, when the temperature of the compressor is higher than the predetermined temperature, the first operation control unit 21 sets the first fan as compared with the case where the temperature of the compressor is lower than the predetermined temperature. Rotate fast.
　代用値運転について説明する。代用値運転を実施するとは、通信線５０に異常が発生したときに、第１の運転制御部２１が、第１の識別部２３の設定および運転モードに応じて、第１のアクチュエータ装置２２に備えられる圧縮機およびファンを制御することである。ここで、第１の運転制御部２１が用いる運転モードは、通信線５０の通信異常が発生する前に室内機３０から取得した運転モードである。また、代用値運転を実施しないとは、通信線５０に異常が発生したときに、第１の運転制御部２１が、第１のアクチュエータ装置２２に備えられる圧縮機およびファンを停止するという事である。代用値運転は、通信線５０に異常が発生したと考えられるときに一時的に実施される運転であり、通信線５０に異常が発生したことが確定した場合、第１の運転制御部２１が、第１のアクチュエータ装置２２を停止させる。 Explain the substitute value operation. When a substitute value operation is performed, when an abnormality occurs in the communication line 50, the first operation control unit 21 causes the first actuator device 22 to perform the operation according to the setting and the operation mode of the first identification unit 23. It is to control the compressor and fan provided. Here, the operation mode used by the first operation control unit 21 is an operation mode acquired from the indoor unit 30 before the communication abnormality of the communication line 50 occurs. Further, not performing the substitute value operation means that the first operation control unit 21 stops the compressor and the fan provided in the first actuator device 22 when an abnormality occurs in the communication line 50. is there. The substitute value operation is an operation that is temporarily performed when it is considered that an abnormality has occurred in the communication line 50, and when it is determined that an abnormality has occurred in the communication line 50, the first operation control unit 21 moves. , The first actuator device 22 is stopped.
　図４は、実施の形態にかかる第１の運転制御部２１が代用値運転の実施の可否を決定するときの流れを示すフローチャートである。第１の運転制御部２１は、第１のアクチュエータ装置２２が動作中であるか確認する（ステップＳ１１）。第１のアクチュエータ装置２２が動作中である場合（ステップＳ１１，Ｙｅｓ）、第１の運転制御部２１は、通信線５０の通信状態を監視して、通信異常が発生したか検知する（ステップＳ１２）。通信線５０の異常を検知する方法は、例えば、第１の運転制御部２１と第２の運転制御部３１とが定期的に温度情報を送受信させるようにし、第１の運転制御部２１が、あらかじめ定められた時間を経過しても温度情報を受信できないとき、通信線５０に異常が発生したと検知する方法が挙げられる。第１のアクチュエータ装置２２が停止中である場合（ステップＳ１１，Ｎｏ）、第１の運転制御部２１は、通信線５０の異常の検知は実施せず処理は完了する。 FIG. 4 is a flowchart showing a flow when the first operation control unit 21 according to the embodiment determines whether or not to implement the substitute value operation. The first operation control unit 21 confirms whether the first actuator device 22 is operating (step S11). When the first actuator device 22 is operating (steps S11, Yes), the first operation control unit 21 monitors the communication state of the communication line 50 and detects whether a communication abnormality has occurred (step S12). ). As a method of detecting an abnormality in the communication line 50, for example, the first operation control unit 21 and the second operation control unit 31 are made to periodically transmit and receive temperature information, and the first operation control unit 21 is used. When the temperature information cannot be received even after the lapse of a predetermined time, a method of detecting that an abnormality has occurred in the communication line 50 can be mentioned. When the first actuator device 22 is stopped (steps S11, No), the first operation control unit 21 does not detect an abnormality in the communication line 50 and completes the process.
　通信異常を検知した場合（ステップＳ１２，Ｙｅｓ）、第１の運転制御部２１は、第１の識別部２３の設定がオンであるか確認する（ステップＳ１３）。第１の識別部２３の設定がオンである場合（ステップＳ１３，Ｙｅｓ）、第１の運転制御部２１は、代用値運転を実施する（ステップＳ１４）。第１の識別部２３の設定がオフである場合（ステップＳ１３，Ｎｏ）、第１の運転制御部２１は、代用値運転を実施せず、通信異常が発生したことを確定させ第１のアクチュエータ装置２２を停止させる（ステップＳ１５）。第１の識別部２３および第２の識別部３３の設定のオン、オフは空気調和機１０の設置時に設置業者によって設定されても良いし、操作装置４０によって設定されてもよい。通信異常を検知しない場合（ステップＳ１２，Ｎｏ）、処理は最初に戻る。 When a communication abnormality is detected (step S12, Yes), the first operation control unit 21 confirms whether the setting of the first identification unit 23 is on (step S13). When the setting of the first identification unit 23 is on (step S13, Yes), the first operation control unit 21 executes the substitute value operation (step S14). When the setting of the first identification unit 23 is off (steps S13, No), the first operation control unit 21 does not perform the substitute value operation, determines that a communication abnormality has occurred, and determines that a communication abnormality has occurred, and the first actuator. The device 22 is stopped (step S15). The on / off setting of the first identification unit 23 and the second identification unit 33 may be set by the installer when the air conditioner 10 is installed, or may be set by the operating device 40. If no communication error is detected (step S12, No), the process returns to the beginning.
　代用値運転を実施するとき、第１の運転制御部２１は、記憶部２５から取得した情報を基に代用値を決定し、代用値を用いて第１のアクチュエータ装置２２を動作させる（ステップＳ１６）。具体的には、第１の運転制御部２１は、通信線５０に異常が発生した場合、室内の温度情報の代用値を、記憶部２５に保存されている室内の温度情報および運転モードを用いて決定し、代用値に基づいて第１のアクチュエータ装置２２を動作させる。代用値とは、代用値運転を実施するときに設定される温度の値であり、第１の運転制御部２１は、代用値に応じて第１のアクチュエータ装置２２を制御する。代用値の詳細については後述する。 When the substitute value operation is performed, the first operation control unit 21 determines the substitute value based on the information acquired from the storage unit 25, and operates the first actuator device 22 using the substitute value (step S16). ). Specifically, when an abnormality occurs in the communication line 50, the first operation control unit 21 uses the indoor temperature information and the operation mode stored in the storage unit 25 as a substitute value for the indoor temperature information. The first actuator device 22 is operated based on the substitute value. The substitute value is a temperature value set when the substitute value operation is performed, and the first operation control unit 21 controls the first actuator device 22 according to the substitute value. The details of the substitute value will be described later.
　代用値運転の実施中は、第１の運転制御部２１は、通信異常が発生していても第１のアクチュエータ装置２２の動作を停止することなく、室外機２０の運転を継続させる。代用値運転の実施中も第１の運転制御部２１は通信線５０の通信状態の異常の検知を実施し、通信状態が正常に戻った場合は、通信異常がなくなったとして、代用値運転を終了し、通常の運転に戻る。 During the substitute value operation, the first operation control unit 21 continues the operation of the outdoor unit 20 without stopping the operation of the first actuator device 22 even if a communication abnormality occurs. The first operation control unit 21 detects an abnormality in the communication state of the communication line 50 even during the substitute value operation, and when the communication state returns to normal, it is assumed that the communication abnormality has disappeared and the substitute value operation is performed. Finish and return to normal operation.
　図５は、実施の形態にかかる第２の運転制御部３１が代用値運転の実施の可否を決定するときの流れを示すフローチャートである。第２の運転制御部３１は、第２のアクチュエータ装置３２が動作中であるか確認する（ステップＳ２１）。第２のアクチュエータ装置３２が動作中である場合（ステップＳ２１，Ｙｅｓ）、第２の運転制御部３１は、通信線５０の通信状態を監視して、通信異常が発生したか検知する（ステップＳ２２）。第２のアクチュエータ装置３２が停止中である場合（ステップＳ２１，Ｎｏ）、第２の運転制御部３１は、通信線５０の異常の検知は実施せず処理は完了する。 FIG. 5 is a flowchart showing a flow when the second operation control unit 31 according to the embodiment determines whether or not to implement the substitute value operation. The second operation control unit 31 confirms whether the second actuator device 32 is operating (step S21). When the second actuator device 32 is operating (steps S21, Yes), the second operation control unit 31 monitors the communication state of the communication line 50 and detects whether a communication abnormality has occurred (step S22). ). When the second actuator device 32 is stopped (steps S21, No), the second operation control unit 31 does not detect the abnormality of the communication line 50 and completes the process.
　通信異常の発生を検知した場合（ステップＳ２２，Ｙｅｓ）、第２の運転制御部３１は、第２の識別部３３の設定がオンであるか確認する（ステップＳ２３）。第２の識別部３３の設定がオンである場合（ステップＳ２３，Ｙｅｓ）、第２の運転制御部３１は、代用値運転を実施する（ステップＳ２４）。第２の識別部３３の設定がオフである場合（ステップＳ２３，Ｎｏ）、第２の運転制御部３１は、代用値運転を実施せず、通信異常が発生したことを確定させ第２のアクチュエータ装置３２を停止させる（ステップＳ２５）。また、第２の運転制御部３１は、通信異常が発生したことを知らせる第１の表示コードを操作装置４０に送信する。操作装置４０は、第１の表示コードを、ディスプレイに表示する。通信異常を検知しない場合（ステップＳ２２，Ｎｏ）、処理は最初に戻る。 When the occurrence of a communication abnormality is detected (step S22, Yes), the second operation control unit 31 confirms whether the setting of the second identification unit 33 is ON (step S23). When the setting of the second identification unit 33 is on (step S23, Yes), the second operation control unit 31 performs the substitute value operation (step S24). When the setting of the second identification unit 33 is off (steps S23, No), the second operation control unit 31 does not perform the substitute value operation, determines that a communication abnormality has occurred, and determines that a communication error has occurred, and the second actuator. The device 32 is stopped (step S25). In addition, the second operation control unit 31 transmits a first display code notifying that a communication abnormality has occurred to the operation device 40. The operation device 40 displays the first display code on the display. If no communication error is detected (steps S22, No), the process returns to the beginning.
　代用値運転を実施するとき、第２の運転制御部３１は、第１の識別部２３および第２の識別部３３の設定に応じた制御を行う（ステップＳ２６）。代用値運転を実施するときの第２の運転制御部３１の動作は後述する。第２の運転制御部３１は、代用値運転中であることを知らせる注意喚起のための第２の表示コードを操作装置４０に送信する（ステップＳ２７）。操作装置４０は、第２の表示コードを、ディスプレイに表示させる。第２の運転制御部３１は、代用値運転の実施中においても通信線５０の通信状態の異常の検知を実施し、通信状態が正常に戻った場合は、代用値運転を終了し、通常の運転に戻る（ステップＳ２８）。第２の運転制御部３１は、通常の運転に戻ったとき、操作装置４０に第２の表示コードの表示を停止させる。 When the substitute value operation is performed, the second operation control unit 31 performs control according to the settings of the first identification unit 23 and the second identification unit 33 (step S26). The operation of the second operation control unit 31 when the substitute value operation is performed will be described later. The second operation control unit 31 transmits a second display code for alerting that the substitute value operation is in progress to the operation device 40 (step S27). The operating device 40 causes the display to display the second display code. The second operation control unit 31 detects an abnormality in the communication state of the communication line 50 even during the substitute value operation, and when the communication state returns to normal, ends the substitute value operation and is normal. Return to operation (step S28). When the second operation control unit 31 returns to the normal operation, the operation device 40 stops the display of the second display code.
　図６は、実施の形態にかかる室外機２０および室内機３０の代用値運転の内容を示す図である。室外機２０と室内機３０とは通信が正常な間に、第１の識別部２３および第２の識別部３３の設定の内容を共有する。室外機２０において、第１の識別部２３の設定がオフである場合、第１の運転制御部２１は、第１のアクチュエータ装置２２の圧縮機およびファンを停止する。第１の識別部２３の設定がオンであって、第２の識別部３３の設定がオフである場合、第１の運転制御部２１は、第１のアクチュエータ装置２２の圧縮機およびファンの運転を継続する。第１の識別部２３の設定がオンであって、第２の識別部３３の設定がオフの場合、第１の運転制御部２１は、代用値運転を実施しない。第１の識別部２３の設定がオンであって、第２の識別部３３の設定がオフの場合に代用値運転を実施しない理由は、第１のアクチュエータ装置２２が備えるファンおよび圧縮機が動作し、第２のアクチュエータ装置３２が備えるファンが動作しない場合、熱交換に不具合が生じるためである。 FIG. 6 is a diagram showing the contents of substitute value operation of the outdoor unit 20 and the indoor unit 30 according to the embodiment. While the communication between the outdoor unit 20 and the indoor unit 30 is normal, the contents of the settings of the first identification unit 23 and the second identification unit 33 are shared. In the outdoor unit 20, when the setting of the first identification unit 23 is off, the first operation control unit 21 stops the compressor and the fan of the first actuator device 22. When the setting of the first identification unit 23 is on and the setting of the second identification unit 33 is off, the first operation control unit 21 operates the compressor and the fan of the first actuator device 22. To continue. When the setting of the first identification unit 23 is on and the setting of the second identification unit 33 is off, the first operation control unit 21 does not perform the substitute value operation. The reason why the substitute value operation is not performed when the setting of the first identification unit 23 is on and the setting of the second identification unit 33 is off is that the fan and the compressor provided in the first actuator device 22 operate. However, if the fan included in the second actuator device 32 does not operate, a problem occurs in heat exchange.
　室内機３０において、第２の識別部３３の設定がオフであって、第１の識別部２３の設定がオフである場合、第２の運転制御部３１は、第２のアクチュエータ装置３２のファンを停止させる。第２の識別部３３の設定がオフであって、第１の識別部２３の設定がオンである場合、第２の運転制御部３１は、代用値運転を実施しない。第２の識別部３３の設定がオンであって、第１の識別部２３の設定がオフであって、通信異常となる前に操作装置４０から取得した運転モードが冷房である場合は、第２の運転制御部３１は、送風の役割として、第２の温度検出部３４が取得する室内の温度が設定温度に達するまでファンを運転させる。 In the indoor unit 30, when the setting of the second identification unit 33 is off and the setting of the first identification unit 23 is off, the second operation control unit 31 is the fan of the second actuator device 32. To stop. When the setting of the second identification unit 33 is off and the setting of the first identification unit 23 is on, the second operation control unit 31 does not perform the substitute value operation. When the setting of the second identification unit 33 is on, the setting of the first identification unit 23 is off, and the operation mode acquired from the operation device 40 before the communication abnormality occurs is cooling, the second identification unit 33 is set. The operation control unit 31 of No. 2 operates the fan until the temperature in the room acquired by the second temperature detection unit 34 reaches the set temperature, as a role of blowing air.
　第２の識別部３３がオンであって、第１の識別部２３の設定がオフであって、通信異常となる前に操作装置４０から取得した運転モードが暖房である場合は、ファンは冷風を送ることになるため第２の運転制御部３１は、第２のアクチュエータ装置３２のファンを停止させる。第２の識別部３３がオンであって、第１の識別部２３がオンである場合、第２の運転制御部３１は、運転モードにかかわらず第２のアクチュエータ装置３２のファンを第２の温度検出部３４が取得する室内の温度が設定温度に達するまで動作させる。また、第２の運転制御部３１は、第２の識別部３３の設定がオフである場合、操作装置４０に通信異常を示す第１の表示コードを表示させる。また、第２の運転制御部３１は、第２の識別部３３がオンである場合、操作装置４０に注意喚起のメッセージを示す第２の表示コードを表示させる。 When the second identification unit 33 is on, the setting of the first identification unit 23 is off, and the operation mode acquired from the operation device 40 before the communication abnormality occurs is heating, the fan is cold air. The second operation control unit 31 stops the fan of the second actuator device 32. When the second identification unit 33 is on and the first identification unit 23 is on, the second operation control unit 31 sets the fan of the second actuator device 32 to the second regardless of the operation mode. It is operated until the temperature in the room acquired by the temperature detection unit 34 reaches the set temperature. Further, when the setting of the second identification unit 33 is off, the second operation control unit 31 causes the operation device 40 to display the first display code indicating a communication abnormality. Further, when the second identification unit 33 is on, the second operation control unit 31 causes the operation device 40 to display a second display code indicating a warning message.
　代用値について説明する。図７は、第１の運転制御部２１が代用値を決定するときに用いる温度の変化を示す図である。図７において、縦軸は室内温度を示す。図７において、横軸は、時間を示す。また、図７は、空気調和機１０の運転モードが冷房であるときの図である。温度５１は、操作装置４０によって空気調和機１０の運転が開始したときの温度である。温度５２および５４は、空気調和機１０の運転によって室内温度が下がり、操作装置４０で設定した温度に達したときの温度である。温度５３および５５は、操作装置４０で設定した温度に達したことで空気調和機１０の運転が一旦停止したことによって室内温度が上がり、再度空気調和機１０の運転が再開するときの温度である。温度５１～５５は、室内機３０の温度情報に含まれる情報である。図７においては、温度５２が設定温度である。 Explain the substitute value. FIG. 7 is a diagram showing a change in temperature used by the first operation control unit 21 when determining a substitute value. In FIG. 7, the vertical axis represents the room temperature. In FIG. 7, the horizontal axis represents time. Further, FIG. 7 is a diagram when the operation mode of the air conditioner 10 is cooling. The temperature 51 is the temperature at which the operation of the air conditioner 10 is started by the operating device 40. The temperatures 52 and 54 are the temperatures at which the room temperature is lowered by the operation of the air conditioner 10 and reaches the temperature set by the operating device 40. The temperatures 53 and 55 are the temperatures at which the room temperature rises due to the temporary stop of the operation of the air conditioner 10 when the temperature set by the operating device 40 is reached, and the operation of the air conditioner 10 is restarted again. .. The temperatures 51 to 55 are information included in the temperature information of the indoor unit 30. In FIG. 7, the temperature 52 is the set temperature.
　第１の運転制御部２１は、室内の温度情報の代用値を、窓の数、日当たり、室内の在籍人数などの室内の環境が大きく変わらないことを前提として、記憶部２５に保存される第２の温度検出部３４が検出する室内の温度情報および運転モードを用いて決定する。また、図７では、空気調和機１０の運転により温度５１から室内温度が下がり、設定温度すなわち温度５２に達すると第１のアクチュエータ装置２２の圧縮機が停止する。この後、室内温度が上がり温度５３に達することで、第１のアクチュエータ装置２２の圧縮機が動作する。代用値運転では、これらの動作を繰り返す前提で空気調和機１０を動作させる。具体的には、例えば、運転モードが冷房である場合、記憶部２５に保存される第２の温度検出部３４が検出する室内の温度情報の中で一番高い温度、つまり温度５１を代用値とすることが挙げられる。また、例えば、運転モードが暖房である場合、第１の運転制御部２１は、記憶部２５に保存される第２の温度検出部３４が検出する室内の温度情報の中で一番低い温度を代用値とすることが挙げられる。 The first operation control unit 21 stores the substitute value of the temperature information in the room in the storage unit 25 on the premise that the indoor environment such as the number of windows, the sunlight, and the number of registered people in the room does not change significantly. It is determined using the indoor temperature information and the operation mode detected by the temperature detection unit 34 of 2. Further, in FIG. 7, the room temperature drops from the temperature 51 due to the operation of the air conditioner 10, and when the set temperature, that is, the temperature 52 is reached, the compressor of the first actuator device 22 is stopped. After that, when the room temperature rises and reaches the temperature 53, the compressor of the first actuator device 22 operates. In the substitute value operation, the air conditioner 10 is operated on the premise that these operations are repeated. Specifically, for example, when the operation mode is cooling, the highest temperature in the room temperature information detected by the second temperature detection unit 34 stored in the storage unit 25, that is, the temperature 51 is used as a substitute value. Is mentioned. Further, for example, when the operation mode is heating, the first operation control unit 21 sets the lowest temperature in the room temperature information detected by the second temperature detection unit 34 stored in the storage unit 25. It can be used as a substitute value.
　しかしながら、代用値運転中は、第１の運転制御部２１は、最新の室内の温度情報を得ることができない。このため、第１の運転制御部２１は、いつ室内が設定温度に達したかわからない。したがって、第１の運転制御部２１は、第１のアクチュエータ装置２２の圧縮機の動作を制御するために、例えば、室内の温度が温度５１から温度５２に達したときの圧縮機の動作を継続させた時間と、温度５２から温度５３に達したときの圧縮機の停止を継続させた時間とを記憶部２５に保存させる。また、第１の運転制御部２１は、代用値運転中に記憶部２５に保存される圧縮機の動作を継続させた時間および圧縮機の停止を継続させた時間で、圧縮機を動作および停止させる。これらの動作を行うことで、第１の運転制御部２１は、圧縮機を制御することができる。 However, during the substitute value operation, the first operation control unit 21 cannot obtain the latest indoor temperature information. Therefore, the first operation control unit 21 does not know when the indoor temperature reaches the set temperature. Therefore, in order to control the operation of the compressor of the first actuator device 22, for example, the first operation control unit 21 continues the operation of the compressor when the temperature in the room reaches the temperature 51 to 52. The storage unit 25 stores the time for which the compressor is allowed to stop and the time for which the compressor is continued to stop when the temperature reaches the temperature from 52 to 53. Further, the first operation control unit 21 operates and stops the compressor at a time during which the operation of the compressor stored in the storage unit 25 is continued and a time during which the compressor is stopped during the substitute value operation. Let me. By performing these operations, the first operation control unit 21 can control the compressor.
　室内の環境は大きく変わることはないため、第１の運転制御部２１は、空気調和機１０の過去の室内の温度情報を用いて代用値運転中、室外機２０の圧縮機およびファンの運転を実施する。なお、代用値運転を実施するとき第１の運転制御部２１は、第１のアクチュエータ装置２２つまり第１のファンおよび圧縮機を制御するが、このとき第１のファンのみまたは圧縮機のみを動作させるようにしてもよい。 Since the indoor environment does not change significantly, the first operation control unit 21 uses the past indoor temperature information of the air conditioner 10 to operate the compressor and fan of the outdoor unit 20 during the substitute value operation. carry out. When the substitute value operation is performed, the first operation control unit 21 controls the first actuator device 22, that is, the first fan and the compressor, but at this time, only the first fan or the compressor is operated. You may let it.
　以上説明したように、本実施の形態では、室内機３０と室外機２０とを接続する通信線５０が故障した場合、第１の運転制御部２１は、室内機３０の室内の温度情報を用いて代用する温度を求め室外機２０に代用値運転を開始させる。代用値運転を実施するときに設定される温度はあらかじめ定められた値ではなく、通信線５０が故障する前の空気調和機１０の温度情報を用いて決定される。このように、本実施の形態では空気調和機１０の運転および停止の判断を室外機２０側で実施し、通信線５０に異常が発生した場合に室外機２０が用いる温度情報は、あらかじめ定められた温度情報ではないため、室内機３０と室外機２０とを接続する通信線５０に異常が発生した場合でも、実際の室内の温度に適した運転を継続することができる。 As described above, in the present embodiment, when the communication line 50 connecting the indoor unit 30 and the outdoor unit 20 fails, the first operation control unit 21 uses the indoor temperature information of the indoor unit 30. The temperature to be substituted is obtained, and the outdoor unit 20 is started to operate at the substitute value. The temperature set when the substitute value operation is performed is not a predetermined value, but is determined by using the temperature information of the air conditioner 10 before the communication line 50 fails. As described above, in the present embodiment, the operation and stop of the air conditioner 10 are determined on the outdoor unit 20 side, and the temperature information used by the outdoor unit 20 when an abnormality occurs in the communication line 50 is predetermined. Since it is not the temperature information, even if an abnormality occurs in the communication line 50 connecting the indoor unit 30 and the outdoor unit 20, the operation suitable for the actual indoor temperature can be continued.
