However, when the indoor unit control board 20 is replaced, the air conditioner 10 enters a state in which no operation history data is stored in the indoor unit external storage 24 . Therefore, the indoor unit control unit 22 determines whether or not the operation history data is stored in the indoor unit external storage 24 when the air conditioner 10 starts operating in step S210.

It is stored in the storage 24 and saved. As a result, all the past operation history data of the air conditioner 10 are restored to the indoor unit external storage 24 mounted on the new indoor unit control board 20 that has been replaced. After that, the process proceeds to step S120 described above.
　なお、室内機制御基板２０の交換は、空気調和機１０の運転が停止された状態において実施され、空気調和機１０の運転中には実施されない。このため、ステップＳ２２０における判定は、空気調和機１０が運転を開始した後にステップＳ１２０からステップＳ１５０の一連の処理が実施される前に実施されればよい。 The replacement of the indoor unit control board 20 is performed while the operation of the air conditioner 10 is stopped, and is not performed while the air conditioner 10 is in operation. Therefore, the determination in step S220 may be performed after the air conditioner 10 starts operating and before the series of processes from step S120 to step S150 are performed.

Specifically, the outdoor unit control unit 32 transmits a history request command, which is a command requesting transmission of operation history data, to the indoor unit control unit 22 or the inverter control unit 42 via the outdoor unit communication unit 31 .
　ステップＳ３４０において、室外機制御部３２が、運転履歴データを受信する。具体的に、履歴要求コマンドを受信した室内機制御部２２またはインバータ制御部４２が、履歴要求コマンドに対応して、運転履歴データを室外機制御部３２に送信する。 At step S340, the outdoor unit control unit 32 receives the driving history data. Specifically, the indoor unit control unit 22 or the inverter control unit 42 that has received the history request command transmits the operation history data to the outdoor unit control unit 32 in response to the history request command.
　具体的に、室内機制御部２２は、室内機外部ストレージ２４に記憶されている空気調和機１０の過去の全ての運転履歴データを、室内機通信部２１を介して室外機制御部３２に送信する。室内機外部ストレージ２４に記憶されている空気調和機１０の過去の全ての運転履歴データは、室内機外部ストレージ２４に記憶されている、室内機１１の運転履歴データ、室外機１２の運転履歴データおよびインバータ５０の運転履歴データである。 Specifically, the indoor unit control unit 22 transmits all past operation history data of the air conditioner 10 stored in the indoor unit external storage 24 to the outdoor unit control unit 32 via the indoor unit communication unit 21. do. All the past operation history data of the air conditioner 10 stored in the indoor unit external storage 24 are the operation history data of the indoor unit 11 and the operation history data of the outdoor unit 12 stored in the indoor unit external storage 24. and operation history data of the inverter 50 .
　また、インバータ制御部４２は、インバータ外部ストレージ４４に記憶されている過去の全ての運転履歴データを、インバータ通信部４１を介して室外機制御部３２に送信する。インバータ外部ストレージ４４に記憶されている空気調和機１０の過去の全ての運転履歴データは、インバータ外部ストレージ４４に記憶されている、室内機１１の運転履歴データ、室外機１２の運転履歴データおよびインバータ５０の運転履歴データである。 In addition, the inverter control unit 42 transmits all past driving history data stored in the inverter external storage 44 to the outdoor unit control unit 32 via the inverter communication unit 41 .

　ステップＳ３５０において、室外機制御部３２が、運転履歴データの復元処理を行う。具体的に、室外機制御部３２が、室内機制御部２２またはインバータ制御部４２から受信した空気調和機１０の過去の全ての運転履歴データを、室外機制御基板３０に実装された室外機外部ストレージ３４に記憶させて、保存する。これにより、空気調和機１０の過去の全ての運転履歴データが、交換された新品の室外機制御基板３０に実装された室外機外部ストレージ３４に復元される。その後、上述したステップＳ１２０に進む。 In step S350, the outdoor unit control section 32 performs restoration processing of the driving history data. Specifically, the outdoor unit control unit 32 stores all past operation history data of the air conditioner 10 received from the indoor unit control unit 22 or the inverter control unit 42 as It is stored in the storage 34 and saved. As a result, all past operation history data of the air conditioner 10 is restored to the outdoor unit external storage 34 mounted on the new outdoor unit control board 30 that has been replaced. After that, the process proceeds to step S120 described above.
　なお、室外機制御基板３０の交換は、空気調和機１０の運転が停止された状態において実施され、空気調和機１０の運転中には実施されない。このため、ステップＳ３２０における判定は、空気調和機１０が運転を開始した後にステップＳ１２０からステップＳ１５０の一連の処理が実施される前に実施されればよい。 The replacement of the outdoor unit control board 30 is performed while the operation of the air conditioner 10 is stopped, and is not performed while the air conditioner 10 is in operation. Therefore, the determination in step S320 may be performed after the air conditioner 10 starts operating and before the series of processes from step S120 to step S150 are performed.
　また、インバータ外部ストレージ４４への運転履歴データの復元動作も、上述した室内機外部ストレージ２４への運転履歴データの復元動作および室外機外部ストレージ３４への運転履歴データの復元動作と同様にして行われる。 In addition, the restoration operation of the driving history data to the inverter external storage 44 is performed in the same manner as the restoration operation of the driving history data to the indoor unit external storage 24 and the restoration operation of the driving history data to the outdoor unit external storage 34 described above. will be
　空気調和機１０は、上述した動作を行うことにより、制御基板の交換が発生した場合においても、特に人的な作業の必要がなく、交換された古い制御基板が保持していた運転履歴データが消失することなく、運転履歴データを空気調和機１０内の各制御基板に蓄積し続けることができる。 By performing the above-described operations, the air conditioner 10 does not require any human work even when the control board is replaced, and the operation history data held by the replaced old control board can be saved. Operation history data can be continuously stored in each control board in the air conditioner 10 without being lost.
　そして、空気調和機１０は、アクチュエータの積算運転時間および故障履歴といった運転履歴データを空気調和機１０内の各制御基板の外部ストレージにバックアップしておくことで、ある制御基板が交換されても、空気調和機１０内の外部ストレージに保存されている運転履歴データから、空気調和機１０が備える機器の不具合原因の特定を確実かつ短時間で行えるという効果を有する。 The air conditioner 10 backs up the operation history data such as the accumulated operation time and failure history of the actuators in the external storage of each control board in the air conditioner 10, so that even if a certain control board is replaced, There is an effect that it is possible to identify the cause of the malfunction of the equipment provided in the air conditioner 10 reliably and in a short time from the operation history data saved in the external storage in the air conditioner 10 .
　また、空気調和機１０は、アクチュエータの積算運転時間および故障履歴といった運転履歴データを空気調和機１０内の各制御基板の外部ストレージにバックアップしておくことで、アクチュエータなどの経年劣化部品の運転時間が制御基板の交換後も空気調和機１０内に保持される。これにより、空気調和機１０は、空気調和機１０内に保持された運転履歴データから経年劣化部品の寿命を予測し、経年劣化部品の確実かつ迅速なメンテナンスを行えるという効果を有する。 In addition, the air conditioner 10 backs up operation history data such as the cumulative operation time and failure history of the actuators in the external storage of each control board in the air conditioner 10, thereby reducing the operation time of aged deterioration parts such as actuators. is retained in the air conditioner 10 even after the control board is replaced. As a result, the air conditioner 10 predicts the service life of aged deterioration parts from the operation history data held in the air conditioner 10, and has the effect of being able to reliably and quickly perform maintenance of the aged deterioration parts.
　また、空気調和機１０は、運転履歴データを空気調和機１０内の各制御基板の外部ストレージにバックアップさせているので、空気調和機１０内の全ての制御基板または空気調和機１０内の全ての外部ストレージが破損しない限り、運転履歴データを保存して運転履歴データの復元に利用できるという効果が得られる。 In addition, since the air conditioner 10 backs up the operation history data in the external storage of each control board in the air conditioner 10, all the control boards in the air conditioner 10 or all the data in the air conditioner 10 As long as the external storage is not damaged, the driving history data can be saved and used to restore the driving history data.
　特に室外機１２のアクチュエータ５２のうち圧縮機５１は、摩耗部品であり、且つ高額な部品である。このため、室外機制御基板３０の交換時に蓄積されていた圧縮機５１の運転履歴データに基づいて圧縮機５１の交換タイミングが正確に把握できれば適切な時期に圧縮機５１を交換ができ、空気調和機１０の使用期間におけるトータルのメンテナンスコストを削減することができる。 In particular, the compressor 51 of the actuator 52 of the outdoor unit 12 is a wear part and an expensive part. Therefore, if the replacement timing of the compressor 51 can be accurately grasped based on the operation history data of the compressor 51 accumulated at the time of replacement of the outdoor unit control board 30, the compressor 51 can be replaced at an appropriate time. It is possible to reduce total maintenance costs during the period of use of the machine 10 .
　また、圧縮機５１を摩耗による故障前に適切に交換できれば、圧縮機５１の故障から圧縮機５１の交換までの、圧縮機５１が使用不能となる期間の発生を回避できる。 Also, if the compressor 51 can be appropriately replaced before it fails due to wear, it is possible to avoid the occurrence of a period in which the compressor 51 is unusable from the time when the compressor 51 fails to the time when the compressor 51 is replaced.
　また、空気調和機１０は、制御基板の交換後においてもアクチュエータの寿命データを正確に収集して調査と予想が可能になるという効果を有する。 In addition, the air conditioner 10 has the effect that even after the control board is replaced, it is possible to accurately collect data on the life of the actuator for investigation and prediction.
　また、制御基板の故障時に同じ制御基板に実装された外部ストレージが故障してしまっても、当該制御基板自体および当該制御基板が制御するアクチュエータの故障直前までの運転履歴データは、空気調和機１０における他の制御基板の外部ストレージに転送されて保存されている。このため、メンテナンスサービス時には他の制御基板の外部ストレージに保存されている運転履歴データを読み出せば、故障した制御基板の故障原因を、メンテナンスサービス時に迅速に特定できるといった効果が得られる。 Further, even if the external storage mounted on the same control board fails when the control board fails, the operation history data up to immediately before the failure of the control board itself and the actuator controlled by the control board will not be stored in the air conditioner 10. transferred to and stored in the external storage of another control board. Therefore, by reading the operation history data stored in the external storage of other control boards during maintenance service, it is possible to quickly identify the cause of the faulty control board during maintenance service.
　さらに、故障した制御基板が制御するアクチュエータの故障の有無、故障した制御基板が制御するアクチュエータの故障原因、故障した制御基板が制御するアクチュエータの交換想定時期についても、空気調和機１０内の他の制御基板の外部ストレージに保存されている運転履歴データを読み出すことで、メンテナンスサービス時に迅速に特定できるといった効果が得られる。 Furthermore, the presence or absence of failure of the actuator controlled by the failed control board, the cause of the failure of the actuator controlled by the failed control board, and the assumed replacement time of the actuator controlled by the failed control board are By reading the operation history data stored in the external storage of the control board, it is possible to obtain the effect of being able to quickly identify the maintenance service.
　上述したように、実施の形態１にかかる空気調和機１０によれば、故障などの理由で空気調和機１０が備える制御基板が交換された場合に、人手を介することなく、運転履歴データの復元必要性の有無を判断し、必要な場合に復元処理を自動で行なうことができる。 As described above, according to the air conditioner 10 according to the first embodiment, even if the control board included in the air conditioner 10 is replaced due to a failure or the like, operation history data can be restored without human intervention. Whether or not it is necessary can be determined, and restoration processing can be automatically performed when necessary.
　そして、実施の形態１にかかる空気調和機１０によれば、室外機１２および室内機１１のみでアクチュエータの運転履歴のデータである運転履歴データの保存およびバックアップを行うことができる、という効果を奏する。 Then, according to the air conditioner 10 according to Embodiment 1, it is possible to save and back up the operation history data, which is the operation history data of the actuator, only with the outdoor unit 12 and the indoor unit 11. .

A storage 66 may be implemented to store driving history data focused on the aforementioned actuators. As a result, it is possible to specify the cause of the failure of the actuator during maintenance service and efficiently replace the actuator with a very small amount of backup storage memory.
　さらに、設計上の都合で、リモコン１３以外の制御基板のみにバックアップストレージを実装しても同様の効果が得られることは言うまでもない。 Furthermore, it goes without saying that the same effect can be obtained even if the backup storage is mounted only on the control board other than the remote controller 13 due to design reasons.

　ステップＳ６１０において、リモコン１３の操作により、室内機外部ストレージ２４に蓄積記憶されている全ての運転履歴データの、室内機バックアップストレージ２６への保存が開始される。すなわち、サービスマンが、リモコン１３を操作することにより、室内機外部ストレージ２４に蓄積記憶されている全ての運転履歴データを室内機バックアップストレージ２６へ記憶させるコマンドを、リモコン制御部６５から室内機制御部２２に送信する。室内機制御部２２は、コマンドを受信すると、室内機外部ストレージ２４に蓄積記憶されている全ての運転履歴データを室内機バックアップストレージ２６へ記憶させる制御を開始する。 In step S610, by operating the remote controller 13, all the operation history data stored in the indoor unit external storage 24 is started to be stored in the indoor unit backup storage 26. That is, by operating the remote controller 13, the serviceman issues a command to store all the operation history data accumulated in the indoor unit external storage 24 in the indoor unit backup storage 26 from the remote control unit 65. 22. Upon receiving the command, the indoor unit control unit 22 starts control to store all the operation history data accumulated and stored in the indoor unit external storage 24 in the indoor unit backup storage 26 .
　ステップＳ６２０において、室内機制御部２２は、室内機外部ストレージ２４に蓄積記憶されている運転履歴データを室内機バックアップストレージ２６へ保存することが不可能であるか否かを判定する。運転履歴データを室内機バックアップストレージ２６へ保存できないと判定された場合は、ステップＳ６２０においてＹｅｓとなり、ステップＳ６３０に進む。運転履歴データを室内機バックアップストレージ２６へ保存できないと判定されない場合は、ステップＳ６２０においてＮｏとなり、ステップＳ６６０に進む。 In step S620, the indoor unit control unit 22 determines whether or not it is impossible to save the driving history data accumulated in the indoor unit external storage 24 to the indoor unit backup storage 26. If it is determined that the driving history data cannot be stored in the indoor unit backup storage 26, the determination in step S620 is Yes, and the process proceeds to step S630. If it is not determined that the driving history data cannot be stored in the indoor unit backup storage 26, the result in step S620 is No, and the process proceeds to step S660.
　ステップＳ６３０において、室内機制御基板２０が交換される。 At step S630, the indoor unit control board 20 is replaced.
　ステップＳ６４０において、リモコン１３の操作により、定期蓄積データの復元処理が行われる。すなわち、サービスマンが、リモコン１３を操作することにより、室外機バックアップストレージ３５またはインバータバックアップストレージ４５に保存されている定期蓄積データを室内機外部ストレージ２４および室内機バックアップストレージ２６に復元させるコマンドを、リモコン制御部６５から室内機制御部２２に送信する。室内機制御部２２は、コマンドを受信すると、室外機バックアップストレージ３５またはインバータバックアップストレージ４５に保存されている定期蓄積データを取得し、室内機外部ストレージ２４および室内機バックアップストレージ２６に記憶させ、保存する。 In step S640, the remote controller 13 is operated to restore the regularly accumulated data. That is, the serviceman operates the remote controller 13 to issue a command to restore the regularly accumulated data stored in the outdoor unit backup storage 35 or the inverter backup storage 45 to the indoor unit external storage 24 and the indoor unit backup storage 26. It is transmitted from the remote controller controller 65 to the indoor unit controller 22 . When receiving the command, the indoor unit control unit 22 acquires the periodical accumulated data stored in the outdoor unit backup storage 35 or the inverter backup storage 45, stores it in the indoor unit external storage 24 and the indoor unit backup storage 26, and saves it. do.
　ステップＳ６５０において、空気調和機１０ａが、リモコン１３のコマンドに基づいて運転を開始する。 At step S650, the air conditioner 10a starts operating based on the command from the remote controller 13.
　ステップＳ６６０において、室内機バックアップストレージ２６への室内機制御基板２０の蓄積データの一時保存処理が行われる。すなわち、室内機制御部２２は、室内機外部ストレージ２４に蓄積記憶されている運転履歴データである室内機制御基板２０の蓄積データを、室内機バックアップストレージ２６に一時保存する。ステップＳ６６０を実施することにより、室内機バックアップストレージ２６に一時記憶されるデータを、一時蓄積データと呼ぶ場合がある。 In step S660, a process of temporarily saving the accumulated data of the indoor unit control board 20 to the indoor unit backup storage 26 is performed. That is, the indoor unit control unit 22 temporarily saves in the indoor unit backup storage 26 the accumulated data of the indoor unit control board 20 , which is the operation history data accumulated in the indoor unit external storage 24 . The data temporarily stored in the indoor unit backup storage 26 by performing step S660 may be referred to as temporary accumulated data.
　ステップＳ６７０において、室内機制御基板２０が交換される。 At step S670, the indoor unit control board 20 is replaced.
　ステップＳ６８０において、リモコン１３の操作により、一時蓄積データの復元処理が行われる。すなわち、サービスマンが、リモコン１３を操作することにより、室内機バックアップストレージ２６に一時保存されている一時蓄積データを室内機外部ストレージ２４および室内機バックアップストレージ２６に復元させるコマンドを、リモコン制御部６５から室内機制御部２２に送信する。室内機制御部２２は、コマンドを受信すると、室内機バックアップストレージ２６に一時保存されている一時蓄積データを、室内機外部ストレージ２４および室内機バックアップストレージ２６に記憶させ、保存する。その後、ステップＳ６５０に進む。 In step S680, the remote controller 13 is operated to restore the temporarily stored data. That is, by operating the remote controller 13, the serviceman issues a command to restore the temporary accumulated data temporarily stored in the indoor unit backup storage 26 to the indoor unit external storage 24 and the indoor unit backup storage 26. to the indoor unit control unit 22. Upon receiving the command, the indoor unit control unit 22 causes the indoor unit external storage 24 and the indoor unit backup storage 26 to store and save the temporary accumulated data temporarily stored in the indoor unit backup storage 26 . After that, the process proceeds to step S650.
　空気調和機１０ａは、上述した処理が行われることにより、空気調和機１０ａが有する全てのバックアップストレージには、全ての制御基板に記憶されている運転履歴データが定期的に記憶される。 The air conditioner 10a periodically stores the operation history data stored in all the control boards in all the backup storages of the air conditioner 10a by performing the above-described processing.
　また、室内機制御基板２０の交換が発生する場合には、室内機制御基板２０の交換前にリモコン１３から室内機制御基板２０を指定したサービス操作を行うことで、対象の制御基板である室内機制御基板２０に保存されている運転履歴データを室内機バックアップストレージ２６に一時保存することができる。また、室内機制御基板２０の交換後には、リモコン１３から操作を行うことで、交換後の室内機制御基板２０の室内機外部ストレージ２４および室内機バックアップストレージ２６に、交換前の室内機制御基板２０の室内機バックアップストレージ２６に一時保存された運転履歴データである一時蓄積データを記憶させ、保存することができる。 Further, when the indoor unit control board 20 needs to be replaced, by performing a service operation specifying the indoor unit control board 20 from the remote controller 13 before replacing the indoor unit control board 20, the indoor unit control board 20, which is the target control board, can be replaced. The operation history data stored in the unit control board 20 can be temporarily stored in the indoor unit backup storage 26 . Further, after the indoor unit control board 20 is replaced, by operating from the remote controller 13, the indoor unit external storage 24 and the indoor unit backup storage 26 of the indoor unit control board 20 after replacement can be stored. Temporarily accumulated data, which is operation history data temporarily stored in the indoor unit backup storage 26 of 20, can be stored and stored.
　もしも、室内機制御基板２０の交換前のリモコン１３の操作時に、室内機制御基板２０の運転履歴データが読み取れない場合は、室内機制御基板２０の交換完了時のリモコン１３の操作により、他の制御基板のバックアップストレージに定期的に記憶されている定期蓄積データを交換後の室内機制御基板２０の室内機外部ストレージ２４および室内機バックアップストレージ２６に記憶させることができる。 If the operation history data of the indoor unit control board 20 cannot be read when operating the remote control 13 before the replacement of the indoor unit control board 20, by operating the remote control 13 after the replacement of the indoor unit control board 20, another Periodically accumulated data periodically stored in the backup storage of the control board can be stored in the indoor unit external storage 24 and the indoor unit backup storage 26 of the indoor unit control board 20 after replacement.
　交換後の室内機制御基板２０に、交換前に一時保存した運転履歴データである一時蓄積データを記憶させることによって、室内機制御基板２０の交換前の最新の運転履歴データを蓄積することができる。 The latest operation history data before the replacement of the indoor unit control board 20 can be accumulated by storing the temporary accumulation data, which is the operation history data temporarily stored before the replacement, in the indoor unit control board 20 after the replacement. .
　もしも、交換前の室内機制御基板２０の故障の程度により、運転履歴データを写すことができなかった場合でも、他の制御基板のバックアップストレージに定期的に記憶されている定期蓄積データから蓄積データを復元できる。 Even if the operation history data cannot be copied due to the degree of failure of the indoor unit control board 20 before replacement, the accumulated data can be obtained from the periodically accumulated data periodically stored in the backup storage of the other control board. can be restored.
　例えば定期的な保存期間を１時間としておけば、室内機制御基板２０が故障しても１時間分の欠損だけで済み、各アクチュエータの実際の運転経過時間からするとごく僅かな欠損で済む。 For example, if the periodical storage period is set to one hour, even if the indoor unit control board 20 fails, only one hour's worth of loss will suffice.
　また、リモコン１３の操作で上記の処理の全てが完結するので、サービスマンは各制御基板に記憶された運転履歴データを読み取るための専用の治工具等をもっている必要がない。 In addition, since all of the above processing is completed by operating the remote controller 13, service personnel do not need to have special jigs and tools for reading the operation history data stored in each control board.
　また、運転履歴データのバックアップ頻度を常時ではなく１時間に一回に減らすことで、室内機制御部２２および通信への処理負荷を軽減することができる。 Also, by reducing the frequency of backing up the driving history data to once an hour rather than all the time, it is possible to reduce the processing load on the indoor unit control unit 22 and communication.
　上記においては、室内機１１のメンテナンスサービス時における処理について説明したが、室外機１２のメンテナンスサービス時において室外機制御基板３０またはインバータ駆動基板４０が交換される場合にも、上記と同様の処理が行われる。 In the above description, the process performed during maintenance service for the indoor unit 11 has been described. However, when the outdoor unit control board 30 or the inverter drive board 40 is replaced during maintenance service for the outdoor unit 12, the same process as described above is performed. done.
　上述したように、実施の形態３では、制御基板の交換が行われた場合でも、定期蓄積データおよび一時蓄積データのうちのどちらかを用いて、交換後の制御基板の外部ストレージおよびバックアップストレージを用いて運転履歴データを復元することができる。 As described above, in the third embodiment, even when the control board is replaced, either the regularly stored data or the temporary stored data is used to restore the external storage and backup storage of the replaced control board. can be used to restore the driving history data.

That is, the service terminal 15 includes a service terminal operation unit, a service terminal display unit, a service terminal storage unit, a service terminal communication unit, and a service terminal control unit (not shown). The service terminal operation unit has functions corresponding to the remote controller operation unit 61 .

By using the service terminal instead of the backup storage, the backup storage mounted on each control board becomes unnecessary, and the single cost of the indoor unit 11 and the outdoor unit 12 can be reduced. This form is particularly effective for products with a large production volume.
　また、実施の形態１にかかる空気調和機１０の構成に対して、サービス用端末１５が追加された構成とすることも可能である。また、実施の形態１にかかる趣旨とは異なるが、別途サービス用の端末を設け、サービス用の端末を外部ストレージの代わりに用いることも可能である。サービス用の端末を外部ストレージの代わりに用いることにより、各制御基板に実装されている外部ストレージが不要となり、室内機１１および室外機１２の単独のコストを削減することができる。 Further, it is possible to adopt a configuration in which the service terminal 15 is added to the configuration of the air conditioner 10 according to the first embodiment. Also, although different from the purpose of the first embodiment, it is possible to provide a service terminal separately and use the service terminal instead of the external storage. By using the service terminal instead of the external storage, the external storage mounted on each control board becomes unnecessary, and the single cost of the indoor unit 11 and the outdoor unit 12 can be reduced.
