Description
なお、制御装置は、室内ファンの回転数を最低回転数未満にならないように室内ファンを制御してもよい。すなわち、除湿運転時、室内ファンは最低回転数以上で駆動される。これにより、室内ファンの回転数が最低回転数より低くなって、回転が不安定になることを回避できる。

- 圧縮機、室外熱交換器、絞り装置、室内熱交換器から冷凍サイクルが形成され、室内熱交換器に室内空気を送る室内ファンと、空調運転に応じて圧縮機の回転数を制御し、圧縮機の回転数に応じて室内ファンを駆動制御する制御装置とを備え、室内熱交換器の温度を検出する温度検出器と、室内の湿度を検出する湿度検出器とが設けられ、制御装置は、除湿運転時に現在の室内の湿度より一定値低い目標湿度を設定し、目標湿度に基づいて算出された露点温度を目標温度とし、目標湿度よりも低く設定された下限湿度の露点温度を下限温度として、室内熱交換器の温度が目標温度と下限温度との間になるように、室内ファンの送風能力を低下させる補正制御を行い、
制御装置は、まず通常の除湿運転を開始した後、補正制御を開始し、室内熱交換器の温度が目標温度より高い場合、送風能力を低下させ、室内熱交換器の温度が目標温度と下限温度との間にあるとき、送風能力を低下させた状態を維持し、補正制御の開始時に室内熱交換器の温度が目標温度よりも低い場合、補正制御を行わずに通常の除湿運転を行うことを特徴とする空気調和機。 - 室内ファンは圧縮機の回転数に対応した基準回転数で駆動され、除湿運転時に制御装置は、室内ファンの回転数を基準回転数より低い回転数に設定して、室内熱交換器の温度に応じて一定間隔で室内ファンの回転数を所定回転数ずつ変化させることを特徴とする請求項1記載の空気調和機。
- 制御装置は、圧縮機の回転数の変化に応じて基準回転数を変化させるとき、変化前の室内ファンの回転数の補正値を維持したまま室内ファンの回転数を変化させ、圧縮機の回転数が所定回転数以下のとき、補正制御を行い、圧縮機の回転数が所定回転数より大のとき、補正制御を行わないことを特徴とする請求項1または2記載の空気調和機。
- 前記下限温度より低い運転下限温度が設定され、制御装置は、室内熱交換器の温度が運転下限温度より高いとき、補正制御を行い、室内熱交換器の温度が運転下限温度以下のとき、圧縮機の回転数を下げる凍結防止制御を行うことを特徴とする請求項1〜3のいずれかに記載の空気調和機。
- 送風方向を制御するルーバが設けられ、室内ファンの送風能力が低下したとき、制御装置は、ルーバを動作させて、送風方向を左右いずれか一方に片寄るように変化させることを特徴とする請求項1〜4のいずれかに記載の空気調和機。
