Description

本発明は、室内機と室外機を接続する空気調和機において、故障時に室内機と室外機がセットになっていなくても原因解析と修理を容易にする制御装置に関するものである。 The present invention relates to an air conditioner that connects an indoor unit and an outdoor unit, and relates to a control device that facilitates cause analysis and repair even if the indoor unit and the outdoor unit are not in a set when a failure occurs.

従来、室内機及び室外機の制御装置に記憶部を設け、生産時にあらかじめ製品の種類や製造番号を記憶させておき、その内容を表示したり、その内容を用いて圧縮機制御の切換を行うなどの手法があった（例えば特許文献１参照）。 Conventionally, a storage unit is provided in the control unit for indoor units and outdoor units, and the type and serial number of the product are stored in advance during production, and the contents are displayed or the compressor control is switched using the contents. (For example, refer to Patent Document 1).

図８は特許文献１に記載の従来の制御装置の構成図である。コントローラ６は、室内機４や室外機５の製品形式を選定する設定部６３、選定した製品形式を記憶する記憶部６４を備え、記憶された製品形式を表示部６２に表示する。
特開平６−２６５２００号公報 FIG. 8 is a configuration diagram of a conventional control device described in Patent Document 1. In FIG. The controller 6 includes a setting unit 63 that selects a product format of the indoor unit 4 or the outdoor unit 5 and a storage unit 64 that stores the selected product format, and displays the stored product format on the display unit 62.
JP-A-6-265200

しかしながら、前記特許文献１では、空気調和機設置時で、室内機と室外機が接続された状態では、室内機は室外機の内容を、室外機は室内機の内容を知ることができるが、空気調和機の故障などにより電源を切られた場合や空気調和機本体が設置場所から撤去され、室内機と室外機が接続されていない状態では、過去接続されていた時の相手の室外機または室内機の内容を知ることができない。その為、故障などで室内機のみが工場などに返却された場合、簡単な故障の場合は、室内機単独での修理は可能だが、複雑な故障内容の場合、空気調和機は室内機と室外機が接続されて始めて正常な動作が可能な為故障に対する解析が十分に実施できず、故障に対する修理が完了しない場合も発生する可能性がある。また、室内機と室外機が両方返却されてきても、どの室内機とどの室外機が接続されていたかを知る手段がない為、十分な解析ができない。 However, in Patent Document 1, when the air conditioner is installed and the indoor unit and the outdoor unit are connected, the indoor unit can know the content of the outdoor unit, and the outdoor unit can know the content of the indoor unit. When the power is turned off due to a malfunction of the air conditioner or when the air conditioner body is removed from the installation location and the indoor unit is not connected to the outdoor unit, the other outdoor unit that was previously connected or I cannot know the contents of the indoor unit. Therefore, if only the indoor unit is returned to the factory due to a failure, etc., in the case of a simple failure, it can be repaired by the indoor unit alone, but in the case of a complicated failure, the air conditioner is connected to the indoor unit and the outdoor unit. Since normal operation is possible only after the machine is connected, failure analysis cannot be sufficiently performed, and repair for failure may not be completed. Moreover, even if both the indoor unit and the outdoor unit are returned, there is no means for knowing which indoor unit and which outdoor unit is connected, and therefore sufficient analysis cannot be performed.

本発明はこのような従来の課題を解決するものであり、空気調和機本体または制御装置が故障にて返却された場合、確実な故障解析とその修理を実施することができる空気調和機の制御装置を提供することを目的とする。 The present invention solves such a conventional problem, and when the air conditioner body or the control device is returned due to a failure, the air conditioner control capable of performing a reliable failure analysis and its repair. An object is to provide an apparatus.

室内機と室外機を接続する空気調和機において、室内機の制御装置及び室外機の制御装置の両方に製造番号を記憶する為の記憶部を設け、空気調和機設置後で室内機と室外機の接続時に、室内機生産時にあらかじめ室内機制御装置の記憶部に記憶された室内機製造番号を室内機から室外機へ送信し、室外機生産時にあらかじめ室外機制御装置の記憶部に記憶された室外機製造番号を室外機から室内機へ送信し、室外機制御装置の記憶部には室内機製造番号を、室内機制御装置の記憶部には室外機製造番号を記憶すると共に、もし、過去送信されてきた製造番号と異なる新たな製造番号が送信された場合には、過去送信された製造番号と新たに送信された製造番号の両方を記憶する。 In an air conditioner that connects an indoor unit and an outdoor unit, both the indoor unit control device and the outdoor unit control device are provided with a storage unit for storing a production number, and the indoor unit and the outdoor unit are installed after the air conditioner is installed. When the indoor unit is connected, the indoor unit production number stored in the storage unit of the indoor unit control device in advance during the production of the indoor unit is transmitted from the indoor unit to the outdoor unit, and stored in the storage unit of the outdoor unit control device in advance during the production of the outdoor unit. The outdoor unit production number is transmitted from the outdoor unit to the indoor unit, the indoor unit production number is stored in the storage unit of the outdoor unit control device, and the outdoor unit production number is stored in the storage unit of the indoor unit control device. When a new manufacturing number different from the transmitted manufacturing number is transmitted, both the previously transmitted manufacturing number and the newly transmitted manufacturing number are stored.

上記構成によって、室内機と室外機を接続する空気調和機において、空気調和機室内機本体または室内機の制御装置のみが故障にて返却された場合、確実な故障解析とその修理を実施することができる空気調和機の制御装置を提供することを目的とする。 With the above configuration, in the air conditioner that connects the indoor unit and the outdoor unit, when only the air conditioner indoor unit main unit or the control unit of the indoor unit is returned due to failure, a reliable failure analysis and its repair shall be performed.
