PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of calculating a mean value of a dust concentration suitable for a starting situation.SOLUTION: An air conditioner for a vehicle includes a dust sensor, an environmental information acquisition section 81 and a calculation section 82. The dust sensor detects a dust concentration in air flowing in an air-conditioning duct. The environmental information acquisition section 81 acquires environmental information that affects detection of the dust concentration performed by the dust sensor. The calculation section 82 sets a movement average time on the basis of the dust concentration detected by the dust sensor, and calculates a mean value of the dust concentration by averaging the dust concentrations detected by the dust sensor by the movement average time. The calculation section 82 sets an initial value at start of the movement average time on the basis of the environmental information acquired by the environmental information acquisition section 81.SELECTED DRAWING: Figure 3 【課題】始動時の状況に適した粉じん濃度の平均値を演算することの可能な車両用空調装置を提供する。【解決手段】車両用空調装置は、粉じんセンサと、環境情報取得部８１と、演算部８２とを備える。粉じんセンサは、空調ダクト内を流れる空気の粉じん濃度を検出する。環境情報取得部８１は、粉じんセンサによる粉じん濃度の検出に影響を与える環境情報を取得する。演算部８２は、粉じんセンサにより検出された粉じん濃度に基づいて移動平均時間を設定するとともに、粉じんセンサにより検出された粉じん濃度を移動平均時間で平均化することにより粉じん濃度の平均値を演算する。演算部８２は、環境情報取得部８１により取得される環境情報に基づいて、移動平均時間の始動時の初期値を設定する。【選択図】図３
