An air conditioner is described for use in an automotive vehicle having an internal combustion engine with an intake air system, an intake port and an intake passage, means is arranged in the intake system for compressing intake air, and a passenger compartment, comprising a refrigerant cycle means where a refrigerant is circulated. The refrigerant cycle means comprises: a compressor of variable displacement type for compressing the refrigerant; a first evaporator connected to the compressor at an inlet for cooling air to be belown into the passenger compartment through heat exchange with the refrigerant; a second evaporator connected to the compressor at the inlet and arranged in the intake passage between the engine and the means for compressing intake air for cooling air to be taken into the engine through heat exchange with the refrigerant; sensing means for detecting a parameter representing one of the boiling pressure of the refrigerant in the first evaporator, and pressure of refrigerant supplied to the compressor; and switch means for causing the first evaporator alone to continue operating when the parameter detected by the sensing means has a value exceeding a predetermined value.
