Air conditioning device and automobile

The invention relates to the technical field of vehicles, in particular to an air conditioning device and an automobile. The air conditioning device comprises a machine shell, an air blower, a refrigeration heat exchanger and a heating heat exchanger, wherein the air blower, the refrigeration heat exchanger and the heating heat exchanger are arranged in the machine shell. The air blower comprises a motor and a centrifugal impeller in transmission connection with the motor, and the motor drives the centrifugal impeller to rotate so that air can enter the centrifugal impeller in the axial direction of the centrifugal impeller and be discharged out of the centrifugal impeller in the radial direction of the centrifugal impeller. According to the air conditioning device, the size is small when the impellers are the same in diameter, and flattening can be achieved easily; under the same volume, the diameter of the impeller of the air blower can be larger than that of a traditional volute type fan, larger air blowin
