Claim:
1. An air conditioner for a vehicle, comprising: a heating heat exchanger and a cooling heat exchanger which are accommodated in a duct; a cycle switching device which switches a refrigerant cycle, through which refrigerant circulates, between a heating circuit, in which refrigerant flows through the heating heat exchanger to heat air blown into a vehicle compartment, and a cooling circuit, in which refrigerant flows through the cooling heat exchanger to cool air blown into the vehicle compartment; a plurality of air outlets through which air in the duct is blown into the vehicle compartment; an air conditioning controller which controls the cycle switching device; a defroster switch operative to command the air conditioning controller to perform a defrosting operation in which air is blown out of the duct toward a windshield of the vehicle through a defroster air outlet of the plurality of air outlets; and a ventilation-mode performing portion configured to limit a flow amount of refrigerant flowing through the cooling heat exchanger and to blow outside air through the cooling heat exchanger into the vehicle compartment from the defroster air outlet for a predetermined time period immediately after an end of the defrosting operation, wherein the air conditioning controller includes a defroster control portion configured to increase a temperature of air blown into the vehicle compartment through the defroster air outlet by a predetermined degree while keeping the refrigerant cycle at a state of the heating circuit during the defrosting operation until the end of the defrosting operation and for the predetermined time period immediately after the end of the defrosting operation.
