冷凍サイクル装置Refrigeration cycle device
　本開示は、冷凍サイクル装置に関する。 This disclosure relates to a refrigeration cycle device.

Information used for controlling the refrigeration cycle device (hereinafter, also referred to as “control information”) is generally recorded in a storage unit provided in the refrigeration cycle device. The storage unit is composed of a RAM (Random Access Memory), a ROM (Read Only Memory), a PROM (Programmable ROM) such as a flash memory, an HDD (Hard Disk Drive), or the like.
　近年、ＩｏＴ（Internet　of　Things）の推進により、通信ネットワークに接続可能な通信装置を備えた冷凍サイクル装置が実用化されている。冷凍サイクル装置が通信ネットワークに接続されることによって、冷凍サイクル装置の動作がより良好となるように更新（バージョンアップ）された制御用情報を、通信ネットワークに接続されたサーバからダウンロードすることが可能となる。 In recent years, with the promotion of IoT (Internet of Things), refrigeration cycle devices equipped with communication devices that can be connected to communication networks have been put into practical use. By connecting the refrigeration cycle device to the communication network, it is possible to download the control information updated (upgraded) so that the refrigeration cycle device operates better from the server connected to the communication network. It becomes.
　例えば、特許第４１０６９４１号公報（特許文献１）には、通信ネットワークを介してサーバと接続可能に構成された冷凍サイクル装置が開示されている。この冷凍サイクル装置においては、冷凍サイクル装置の据付後に更新後の制御用情報をサーバから受信（ダウンロード）し、更新前の制御用情報を更新後の制御用情報に書換えることができる。 For example, Japanese Patent No. 4106941 (Patent Document 1) discloses a refrigerating cycle device configured to be connectable to a server via a communication network. In this refrigeration cycle device, after the refrigeration cycle device is installed, the updated control information can be received (downloaded) from the server, and the pre-update control information can be rewritten into the updated control information.
特許第４１０６９４１号公報Japanese Patent No. 4106941
　冷凍サイクル装置には、運転停止が厳禁となるシーンがある。そのため、冷凍サイクル装置の運転を強制的に停止させることなく制御用情報の書換えを行なうことが望ましい。上述の特許第４１０６９４１号公報（特許文献１）には、このような課題およびその対策について言及されていない。 There is a scene where it is strictly prohibited to stop the operation of the refrigeration cycle device. Therefore, it is desirable to rewrite the control information without forcibly stopping the operation of the refrigeration cycle device. The above-mentioned Japanese Patent No. 4106941 (Patent Document 1) does not mention such a problem and its countermeasures.
　本開示は、上述の課題を解決するためになされたものであって、その目的は、冷凍サイクル装置の運転を強制的に停止させることなく制御用情報の書換えを可能にすることである。 The present disclosure has been made to solve the above-mentioned problems, and an object thereof is to enable rewriting of control information without forcibly stopping the operation of the refrigeration cycle device.
　本開示による冷凍サイクル装置は、圧縮機を含む冷媒回路と、サーバから制御用情報を受信する通信装置と、通信装置が受信した制御用情報を記憶する記憶装置と、記憶装置に記憶された制御用情報を用いて圧縮機を制御する制御装置とを含む。制御装置は、記憶装置に記憶されている第１の制御用情報よりも新しい第２の制御用情報を通信装置が受信し始めた場合、記憶装置への第２の制御用情報の書込みが完了するまでの間は、第１の制御用情報を用いて圧縮機を作動させる第１制御を継続する。 The refrigerating cycle device according to the present disclosure includes a refrigerant circuit including a compressor, a communication device that receives control information from a server, a storage device that stores control information received by the communication device, and a control stored in the storage device. Includes a control device that controls the compressor using information. When the communication device starts to receive the second control information newer than the first control information stored in the storage device, the control device completes writing the second control information to the storage device. Until this is done, the first control for operating the compressor using the first control information is continued.
　本開示による冷凍サイクル装置によれば、第２の制御用情報の受信が開始されてから記憶装置への第２の制御用情報の書込みが完了するまでの間は、圧縮機を強制的に停止させることなく、既存の第１の制御用情報を用いて圧縮機を作動させる。そのため、第２の制御用情報の書込みが完了した後の適切なタイミングで（たとえば使用者の操作によって圧縮機の作動が停止された後）で、制御用情報をの書換えを行なうことができる。その結果、冷凍サイクル装置の運転を強制的に停止させることなく制御用情報の書換えを行うことができる。 According to the refrigeration cycle apparatus according to the present disclosure, the compressor is forcibly stopped from the start of receiving the second control information to the completion of writing the second control information to the storage device. The compressor is operated using the existing first control information without causing the compressor to operate. Therefore, the control information can be rewritten at an appropriate timing after the writing of the second control information is completed (for example, after the operation of the compressor is stopped by the operation of the user). As a result, the control information can be rewritten without forcibly stopping the operation of the refrigeration cycle device.

　［動作の説明］
　クラウドサーバ３００は、候補記憶部３０１ａに記憶される制御用情報が更新された場合、上述の更新情報を冷凍サイクル装置１００に送信する。 [Explanation of operation]
When the control information stored in the candidate storage unit 301a is updated, the cloud server 300 transmits the above-mentioned updated information to the refrigeration cycle device 100.
　以下では、冷凍サイクル装置１００で使用中の既存の制御用情報を「更新前の制御用情報」とも記載し、更新前の制御用情報を利用した冷凍サイクル装置１００の制御を「更新前制御」とも記載する。更新前の制御用情報および更新前制御は、本開示の「第１の制御用情報」および「第１制御」にそれぞれ対応し得る。 In the following, the existing control information used in the refrigeration cycle device 100 is also described as "control information before update", and the control of the refrigeration cycle device 100 using the control information before update is referred to as "pre-update control".

Also described as "post-control". The updated control information and the updated control may correspond to the "second control information" and the "second control" of the present disclosure, respectively.
　また、以下では、更新前の制御用情報は第１記憶部１１３１に記憶され、更新後の制御用情報は第２記憶部１１３２に書き込まれるものとして説明する。 Further, in the following, it will be described that the control information before the update is stored in the first storage unit 1131 and the control information after the update is written in the second storage unit 1132.
　図３は、冷凍サイクル装置１００の制御装置１１０が行う処理手順の一例を示すフローチャートである。冷凍サイクル装置１００は、クラウドサーバ３００から制御用情報の更新情報を受信する（ステップＳ３１）と、クラウドサーバ３００の候補記憶部３０１ａから更新後の制御用情報を取得して第２記憶部１１３２への書込みを開始する（ステップＳ３２）。なお、第１記憶部１１３１に記憶されている更新前の制御用情報は、後述のステップＳ３９の処理で消去されるまで、第１記憶部１１３１に保持される。 FIG. 3 is a flowchart showing an example of a processing procedure performed by the control device 110 of the refrigeration cycle device 100. When the refrigerating cycle device 100 receives the updated information of the control information from the cloud server 300 (step S31), the refrigerating cycle device 100 acquires the updated control information from the candidate storage unit 301a of the cloud server 300 and sends it to the second storage unit 1132. Is started (step S32). The control information before the update stored in the first storage unit 1131 is held in the first storage unit 1131 until it is erased by the process of step S39 described later.
　冷凍サイクル装置１００は、更新後の制御用情報の書込みを開始した後においても、更新前の制御用情報を用いて冷凍サイクル装置１００を制御する「更新前制御」を継続する（ステップＳ３３）。これにより、圧縮機１５３の作動中に更新後の制御用情報の書込みが開始された場合であっても、圧縮機１５３の作動が継続される。 The refrigeration cycle apparatus 100 continues the "pre-update control" that controls the refrigeration cycle apparatus 100 using the pre-update control information even after the writing of the post-update control information is started (step S33). As a result, even if the writing of the updated control information is started during the operation of the compressor 153, the operation of the compressor 153 is continued.
　更新後の制御用情報の書込みが完了する（ステップＳ３４）と、冷凍サイクル装置１００は、たとえば使用者の手動操作による運転停止指令あるいは使用者が設定したタイマー機能による運転停止指令などによって、圧縮機１５３の作動が停止されたか否かを判定する（ステップＳ３５）。圧縮機１５３の作動が継続している場合（ステップＳ３５においてＮＯ）、冷凍サイクル装置１００は、更新前制御を継続する（ステップＳ３６）。その後、処理はステップＳ３５に戻される。 When the writing of the updated control information is completed (step S34), the refrigerating cycle apparatus 100 is subjected to, for example, a compressor by a manual operation stop command by the user or an operation stop command by the timer function set by the user. It is determined whether or not the operation of 153 has been stopped (step S35). When the operation of the compressor 153 continues (NO in step S35), the refrigeration cycle device 100 continues the pre-update control (step S36). After that, the process is returned to step S35.
　圧縮機１５３の作動が停止された場合（ステップＳ３５においてＹＥＳ）、冷凍サイクル装置１００は、自らの制御モードを、更新前の制御用情報を用いる「更新前制御」から、更新後の制御用情報を用いる「更新後制御」へ切り替える（ステップＳ３７）。 When the operation of the compressor 153 is stopped (YES in step S35), the refrigerating cycle apparatus 100 changes its control mode from the "pre-update control" using the pre-update control information to the post-update control information. Switch to "control after update" using (step S37).
　その後、冷凍サイクル装置１００は、たとえば使用者の手動操作による運転開始指令あるいは使用者が設定したタイマー機能による運転開始指令などによって、更新後制御による圧縮機１５３の作動が開始されたか否かを判定する（ステップＳ３８）。更新後制御による圧縮機１５３の作動が開始されていない場合（ステップＳ３８においてＮＯ）、冷凍サイクル装置１００は、圧縮機１５３の作動が再開されるまで待つ。 After that, the refrigerating cycle device 100 determines whether or not the operation of the compressor 153 by the post-update control is started by, for example, an operation start command by the user's manual operation or an operation start command by the timer function set by the user. (Step S38). If the operation of the compressor 153 by the post-update control has not been started (NO in step S38), the refrigeration cycle device 100 waits until the operation of the compressor 153 is restarted.
　更新後制御による圧縮機１５３の作動が開始された場合（ステップＳ３８においてＹＥＳ）、冷凍サイクル装置１００は、第１記憶部１１３１に記憶されている更新前の制御用情報を第１記憶部１１３１から消去する（ステップＳ３９）。 When the operation of the compressor 153 by the post-update control is started (YES in step S38), the refrigerating cycle apparatus 100 transfers the pre-update control information stored in the first storage unit 1131 from the first storage unit 1131. Erase (step S39).
　図４は、冷凍サイクルシステム１が行う処理の概要の一例を示すシーケンス図である。
　図４における初期状態では、冷凍サイクル装置１００において、第１記憶部１１３１に記憶されている既存の更新前の制御用情報を用いて「更新前制御」が実行されている（ステップＳ３０）。 FIG. 4 is a sequence diagram showing an outline of the processing performed by the refrigeration cycle system 1.
In the initial state shown in FIG. 4, in the refrigerating cycle apparatus 100, the “pre-update control” is executed using the existing pre-update control information stored in the first storage unit 1131 (step S30).
　クラウドサーバ３００は、候補記憶部３０１ａに更新後の制御用情報が追加されると、その旨を示す更新情報を候補記憶部３０１ａから取得し（ステップＳ１０）、更新情報を冷凍サイクル装置１００に送信する（ステップＳ１１）。 When the updated control information is added to the candidate storage unit 301a, the cloud server 300 acquires the update information indicating that effect from the candidate storage unit 301a (step S10), and transmits the update information to the refrigeration cycle device 100. (Step S11).
　冷凍サイクル装置１００は、クラウドサーバ３００から更新情報を取得する（ステップＳ３１）と、クラウドサーバ３００の候補記憶部３０１ａから更新後の制御用情報を取得して第２記憶部１１３２への書込みを開始する（ステップＳ３２）。 When the refrigerating cycle device 100 acquires update information from the cloud server 300 (step S31), it acquires updated control information from the candidate storage unit 301a of the cloud server 300 and starts writing to the second storage unit 1132. (Step S32).
　その後、第２記憶部１１３２への更新後の制御用情報の書込みが完了するまでの間は、冷凍サイクル装置１００は、第１記憶部１１３１に記憶されている更新前の制御用情報を利用する更新前制御を継続する（ステップＳ３３）。 After that, until the writing of the updated control information to the second storage unit 1132 is completed, the refrigerating cycle apparatus 100 uses the pre-updated control information stored in the first storage unit 1131. The pre-update control is continued (step S33).
　そして、第２記憶部１１３２への更新後の制御用情報の書込みが完了する（ステップＳ３４）と、冷凍サイクル装置１００は、圧縮機１５３の停止確認を行う（ステップＳ３５）。更新後の制御用情報の書込みが完了した後に初めて圧縮機１５３が停止されるまでは、更新前制御の実行が継続される。 Then, when the writing of the updated control information to the second storage unit 1132 is completed (step S34), the refrigerating cycle apparatus 100 confirms the stop of the compressor 153 (step S35). Execution of the pre-update control is continued until the compressor 153 is stopped for the first time after the writing of the updated control information is completed.
　更新後の制御用情報の書込みが完了した後に初めて圧縮機１５３が停止された後は、冷凍サイクル装置１００は、自らの制御モードを、更新前制御から、第２記憶部１１３２に記憶されている更新後の制御用情報を利用する「更新後制御」に切り替える（ステップＳ３７）。 After the compressor 153 is stopped for the first time after the writing of the updated control information is completed, the refrigerating cycle apparatus 100 stores its own control mode in the second storage unit 1132 from the pre-update control. It switches to "post-update control" that uses the updated control information (step S37).
　その後、冷凍サイクル装置１００は、更新後制御による圧縮機１５３の作動を確認する（ステップＳ３８）。更新後制御による圧縮機１５３の作動が確認された場合、冷凍サイクル装置１００は、第１記憶部１１３１に記憶されている更新前の制御用情報を消去する（ステップＳ３９）。 After that, the refrigeration cycle device 100 confirms the operation of the compressor 153 by the post-update control (step S38). When the operation of the compressor 153 by the post-update control is confirmed, the refrigeration cycle device 100 erases the pre-update control information stored in the first storage unit 1131 (step S39).
　図３および図４には記載していないが、ステップＳ３９の処理後においては、第２記憶部１１３２に記憶されている更新後の制御用情報が、第１記憶部１１３１に移動される。これにより、使用中の既存の制御用情報が第１記憶部１１３１に記憶され、第２記憶部１１３２には制御用情報が記憶されていない状態となる。なお、更新後の制御用情報を第２記憶部１１３２から第１記憶部１１３１に移動するのではなく、第２記憶部１１３２に記憶されている制御用情報をそのまま更新前の制御用情報として扱う（すなわち、第２記憶部１１３２を第１記憶部１１３１として扱う）ようにしてもよい。 Although not shown in FIGS. 3 and 4, after the processing in step S39, the updated control information stored in the second storage unit 1132 is moved to the first storage unit 1131. As a result, the existing control information in use is stored in the first storage unit 1131, and the control information is not stored in the second storage unit 1132. The control information after the update is not moved from the second storage unit 1132 to the first storage unit 1131, but the control information stored in the second storage unit 1132 is treated as it is as the control information before the update. (That is, the second storage unit 1132 may be treated as the first storage unit 1131).
　以上のように、本実施の形態による冷凍サイクル装置１００は、圧縮機１５３を含む冷媒回路１５０と、クラウドサーバ３００から制御用情報を受信する通信装置１４０と、通信装置１４０が受信した制御用情報を記憶する記憶部１１３を含み、記憶部１１３に記憶された制御用情報を用いて圧縮機１５３を制御する制御装置１１０とを含む。 As described above, the refrigerating cycle device 100 according to the present embodiment includes the refrigerant circuit 150 including the compressor 153, the communication device 140 that receives control information from the cloud server 300, and the control information received by the communication device 140. The storage unit 113 is included, and the control device 110 that controls the compressor 153 by using the control information stored in the storage unit 113 is included.
　制御装置１１０は、記憶部１１３に記憶されている更新前の制御用情報よりも新しい更新後の制御用情報を通信装置１４０が受信し始めた場合、記憶部１１３への更新後の制御用情報の書込みが完了するまでの間は、圧縮機１５３を強制的に停止させることなく、運転実績のなる既存の更新前の制御用情報を用いて圧縮機１５３を作動させる更新前制御を継続する。そのため、更新後の制御用情報の書込みが完了した後の適切なタイミングで制御用情報をの書換えを行なうことができる。これにより、冷凍サイクル装置１００の運転を強制的に停止させることなく制御用情報の書換えを行うことができる。 When the communication device 140 starts to receive the updated control information newer than the pre-update control information stored in the storage unit 113, the control device 110 has the updated control information in the storage unit 113. Until the writing is completed, the compressor 153 is not forcibly stopped, and the pre-update control for operating the compressor 153 is continued by using the existing pre-update control information which is the operation record. Therefore, the control information can be rewritten at an appropriate timing after the writing of the updated control information is completed. As a result, the control information can be rewritten without forcibly stopping the operation of the refrigeration cycle device 100.
　特に、本実施の形態による制御装置１１０は、記憶部１１３への更新後の制御用情報の書込みが完了した後に初めて圧縮機１５３の作動が停止されるまでは、更新前制御の実行を継続する。そして、更新後の制御用情報の書込みが完了した後に初めて圧縮機１５３の作動が停止された場合、制御装置１１０は、更新前制御に代えて、更新後の制御用情報を用いて圧縮機１５３を作動させる更新後制御を実行する。このように圧縮機１５３の作動停止中に更新前制御から更新後制御への切替えを行うため、圧縮機１５３を強制的に停止させることなく、更新前制御から更新後制御への切替えを円滑に行うことができる。 In particular, the control device 110 according to the present embodiment continues to execute the pre-update control until the operation of the compressor 153 is stopped for the first time after the writing of the updated control information to the storage unit 113 is completed. .. When the operation of the compressor 153 is stopped for the first time after the writing of the updated control information is completed, the control device 110 uses the updated control information instead of the pre-update control to use the compressor 153. Executes post-update control to activate. In this way, since the switch from the pre-update control to the post-update control is performed while the operation of the compressor 153 is stopped, the switch from the pre-update control to the post-update control can be smoothly performed without forcibly stopping the compressor 153. It can be carried out.
　さらに、本実施の形態による制御装置１１０は、更新後制御によって圧縮機１５３が初めて作動した後に、記憶部１１３に記憶されている更新前の制御用情報を消去する。言い換えれば、更新後制御による圧縮機１５３の作動が確認されるまでは、記憶部１１３に記憶されている更新前の制御用情報を消去せずに保持しておく。そのため、何らかの要因で更新後制御によって圧縮機１５３が作動しない場合において、更新前制御に容易に復旧させることができる。 Further, the control device 110 according to the present embodiment erases the pre-update control information stored in the storage unit 113 after the compressor 153 is operated for the first time by the post-update control. In other words, until the operation of the compressor 153 by the post-update control is confirmed, the pre-update control information stored in the storage unit 113 is retained without being erased. Therefore, when the compressor 153 does not operate due to the post-update control for some reason, it can be easily restored to the pre-update control.
　今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本開示の範囲は上記した説明ではなくて請求の範囲によって示され、請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。 The embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive.
