An air conditioner for a vehicle includes a heat pump system for heating and cooling. The air conditioner includes a ventilation passage for ventilating air from a passenger compartment of the vehicle outside of the vehicle. An accelerating system is provided with the heat pump system for accelerating the evaporation of a refrigerant during air cooling or the condensation of a refrigerant during air heating by using involved energy recovered from air exhausted outside of said vehicle through the ventilation passage. Thereby, the air conditioner increases the heating and cooling ability and reduces the energy necessary for maintaining a constant temperature in the passenger compartment.
