PROBLEM TO BE SOLVED: To provide a vehicular air conditioner capable of preventing noise of a compressor from being recognized while improving cooling performance.SOLUTION: A vehicular air conditioner 10 includes a compressor 41 and an air-conditioning ECU 86. The air-conditioning ECU 86 controls the compressor 41. When vehicle speed is predetermined speed or more, the air-conditioning ECU 86 sets an upper limit value of rotating speed of the compressor 41 to a first upper limit value. When the vehicle speed is less than the predetermined speed and rotating speed of a fan device 70 is less than predetermined rotating speed, the air-conditioning ECU 86 sets the rotating speed of the compressor to a second upper limit value smaller than the first upper limit value. When the vehicle speed is less than the predetermined speed and the rotating speed of the fan device 70 is the predetermined rotating speed or more, the air-conditioning ECU 86 sets the rotating speed of the compressor 41 to a third upper limit value smaller than the first upper limit value and larger than the second upper limit value.SELECTED DRAWING: Figure 3

    【課題】冷房性能を向上させつつも、コンプレッサの騒音を認知し難い車両用空調装置を提供する。【解決手段】車両用空調装置10はコンプレッサ41とエアコンECU86とを備える。エアコンECU86は、コンプレッサ41を制御する。エアコンECU86は、車両の速度が所定速度以上である場合には、コンプレッサ41の回転速度の上限値を第1上限値に設定する。また、エアコンECU86は、車両の速度が所定速度未満であって、且つファン装置70の回転速度が所定回転速度未満である場合には、コンプレッサの回転速度を、第1上限値よりも小さい第2上限値に設定する。さらに、エアコンECU86は、車両の速度が所定速度未満であって、且つファン装置70の回転速度が所定回転速度以上である場合には、コンプレッサ41の回転速度を、第1上限値よりも小さく、且つ第2上限値よりも大きい第3上限値に設定する。【選択図】図3
