PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of keeping a discharged gas condition of a refrigerant compressor within a predetermined range with an inexpensive device constitution, and preventing the deterioration and the fracture of a rubber hose, the seizure malfunction of a compressor, or the like under a high load condition. SOLUTION: In this air conditioner for a vehicle where a front evaporator 9 and a rear evaporator 10 are respectively connected in parallel in a refrigerant circuit, a solenoid valve 5 for the front evaporator, a solenoid valve 6 for the rear evaporator, a temperature-type expansion valve 7 for the front evaporator and a temperature-type expansion valve 8 for the rear evaporator are mounted on the refrigerant inlet sides of both evaporators, a bleed port (by-pass hole) is formed on the temperature-type expansion valve 8 for the rear evaporator, a temperature sensor 11 is mounted for detecting a temperature of the refrigerant gas injected from the refrigerant compressor 2, and a controller 12 is further mounted for opening the solenoid valve 6 for the rear evaporator when a detected value of the temperature sensor 11 reaches an upper limit set value.
