The invention belongs to the technical field of air conditioners of extended-range electric vehicles and hybrid electric vehicles. The invention discloses a double-refrigeration air conditioning system of an extended-range electric vehicle. The system comprises a condenser, an evaporator, a mechanical compressor and an electric compressor, wherein a refrigerant circulating pipeline is arranged between the condenser and the evaporator; and each of a refrigerant output port of the mechanical compressor and a refrigerant output port of the electric compressor is provided with a refrigerant outputone-way valve. The system further comprises a first three-way piece and a second three-way piece, a first port of the first three-way piece is communicated with the outlet end of the evaporator, anda second port and a third port of the first three-way piece are communicated with the mechanical compressor and the electric compressor respectively; a first port of the second three-way piece is communicated with the condenser, and a second port and a third port of the second three-way piece are respectively communicated with the mechanical compressor and the electric compressor. Some functions of a traditional compressor can be effectively utilized, the manufacturing cost of the system can be reduced, and the beneficial effects of being low in fault rate and maintenance rate are achieved.
