To provide a vehicular air conditioner which includes an inside/outside air switching damper and mixes inside air with outside air to send the mixed air, and in which a desired inside/outside air ratio can be maintained when a ram pressure changes.SOLUTION: In an inside/outside air introduction mode in a vehicular air conditioner 10 in which an outside air introduction port 82 and an inside air introduction port 84 are simultaneously opened, the ram pressure of outside air introduced from the outside air introduction port 82 is estimated in a control part 18 on the basis of the vehicle speed of a vehicle, the openings of a side window and a sunroof in the vehicle, an inter-vehicle distance between a vehicle ahead and the vehicle, and weather information. On the basis of the estimated ram pressure, the opening of an inside/outside air switching damper 78 is adjusted by driving a drive part 24, and the amount of the outside air is adjusted, thereby maintaining an inside/outside air ratio.SELECTED DRAWING: Figure 3

    【課題】内外気切替ダンパを有し内気及び外気を混合して送風する車両用空調装置に関し、ラム圧の変化が生じたとき、所望の内外気比率をに維持する。【解決手段】外気導入口82及び内気導入口84を同時に開放する車両用空調装置10の内外気導入モードにおいて、車両の車速、前記車両におけるサイドウィンドウ及びサンルーフの開度、前方車両と車両との車間距離、気象情報に基づいて、前記外気導入口82から導入される外気のラム圧を制御部18において推定する。推定されたラム圧に基づいて、駆動部24を駆動することで内外気切替ダンパ78の開度を調整し、外気の外気量を調整することで内外気比率を維持する。【選択図】図3
