PROBLEM TO BE SOLVED: To provide an air conditioner for vehicle, which reduces a contaminant concentration in a cabin and prevents air having a high contaminant concentration in the air outside the vehicle from entering the cabin.SOLUTION: An air conditioner 1 for vehicle comprises: an inside/outside air switching door 8 for selectively switching between an outside air introduction port 7 and an inside air introduction port 6; required time calculating means 42 for calculating a required time needed for an own vehicle to reach an air pollution area; in-cabin concentration detecting means 50 for detecting a contaminant concentration in the air inside the cabin; and ventilation time calculating means 51 for calculating a ventilation time needed for a detected value by the in-cabin concentration detecting means 50 to drop until a predetermined condition is met after opening the outside air introduction port 7. An actuator 9 controls the inside/outside air switching door 8 in such a manner that it opens the outside air introduction port 7 before the required time becomes shorter than the ventilation time and closes the outside air introduction port 7 after the lapse of the ventilation time. |
