To provide a vehicular air conditioner that can prevent a cooling capability in a vehicle interior from deteriorating when continuously executing control of rising a target evaporation temperature.SOLUTION: An air conditioner ECU 30, when a temperature of cooling water is above or equal to a first predetermined temperature, executes first control by which a target evaporation temperature is set so that the temperature rises by a predetermined temperature and second control by which the target evaporation temperature is changed in accordance with a cooling load in a vehicle interior; when executing the second control after executing the first control, sets a first target evaporation temperature set by the first control as the target evaporation temperature, and calculates a second target evaporation temperature changed by the second control with the target evaporation temperature set just before executing the first control as a reference; and when the second target evaporation temperature becomes higher than the first target evaporation temperature, sets the second target evaporation temperature as the target evaporation temperature.SELECTED DRAWING: Figure 1
【課題】目標蒸発温度を上げる制御を連続して実行した場合に車室内の冷房能力が低下することを防止する車両用空調装置を提供する。【解決手段】エアコンECU30は、冷却水の温度が第1所定温度以上の場合には、目標蒸発温度を所定温度だけ上げて設定する第1制御と、車室内の冷房負荷に応じて目標蒸発温度を変更する第2制御と、を実行し、第1制御を実行後に第2制御を実行する場合には、第1制御によって設定された第1目標蒸発温度を目標蒸発温度として設定し、第1制御を実行直前の目標蒸発温度を基準として第2制御によって変更された第2目標蒸発温度を算出し、第2目標蒸発温度が第1目標蒸発温度より大きくなった場合には、第2目標蒸発温度を目標蒸発温度として設定する。【選択図】図1
