Air conditioner for vehicle

A vehicle air conditioner which cools air to be blown into a vehicle interior by using a refrigeration cycle with an evaporator evaporating refrigerant, the vehicle air conditioner comprising:

• a refrigerant flow-rate control portion controlling a flow rate of the refrigerant flowing into the evaporator;
• a dew-point temperature detection portion detecting a dew-point temperature of air flowing into the evaporator;
• and
• a determination portion determining whether the dew-point temperature detected by the dew-point temperature detection portion is equal to or less than a predetermined reference threshold, wherein
• the refrigerant flow-rate control portion reduces the flow rate of the refrigerant flowing into the evaporator, when the determination portion determines that the dew-point temperature detected by the dew-point temperature detection portion is equal to or less than the predetermined reference threshold.
