上記のことより、複数台個別運転する複数の室内ユニットｎ２１と室外ユニット３を据付け工事５の完了後、機器の電源投入時に通信手段６で互いの冷媒仕様または能力ランクまたは機種形態を認識し、室外ユニット３が接続可能判定することにより、空気調和機の運転を開始する前に接続異常判定することができ、冷媒違いによる機器の損傷及び性能不足、室内ユニットの個々能力ランクの異常な不均一から発生する能力不足、合計能力ランク違いによる機器の寿命短縮及び性能不足、機種形態の違いによる冷凍サイクルの不成立を防止することができる。   From the above, after the installation work 5 is completed for the plurality of indoor units n21 and the outdoor unit 3 that individually operate a plurality of units, the communication means 6 recognizes each other's refrigerant specification or capability rank or model form when the device is turned on. By determining that the outdoor unit 3 can be connected, it is possible to determine a connection abnormality before starting the operation of the air conditioner, damage to equipment due to a difference in refrigerant and insufficient performance, and abnormal unevenness of individual capacity ranks of the indoor unit. It is possible to prevent the shortage of capacity generated from the above, the shortening of the life of the equipment due to the difference in the total capacity rank, the lack of performance, and the failure of the refrigeration cycle due to the difference in the model form.

以上のように、本発明にかかる空気調和機は、室内ユニットと室外ユニットの機器の電源投入時に通信手段で互いの冷媒仕様または能力ランクまたは機種形態を認識し、空気調和機の運転を開始する前に接続異常判定をすることができるので、冷暖機種、冷房専用機種の判定等の用途にも適用できる。   As described above, the air conditioner according to the present invention recognizes the refrigerant specifications or the capability rank or the model form of each other by the communication means when the devices of the indoor unit and the outdoor unit are turned on, and starts the operation of the air conditioner. Since connection abnormality determination can be performed before, it can be applied to uses such as determination of a cooling / heating model and a cooling-only model.
