Abstract:
A hybrid compressor device for a vehicle having an engine that is stopped when the vehicle is temporally stopped, the hybrid compressor device comprising:a pulley rotated by the engine; a motor rotated by electric power from a battery of the vehicle; a compressor for compressing refrigerant in a refrigerant cycle system, the compressor being operated by driving force of the pulley and driving force of the motor; and a transmission mechanism connected respectively independently to a rotational shaft of the pulley, a rotational shaft of the motor and a rotational shaft of the compressor, the transmission mechanism being provided for changing a rotational speed of the pulley and a rotational speed of the motor, to be transmitted to the compressor, wherein: the pulley, the motor and the compressor are disposed to be rotatable independently; and the rotational speed of the compressor is changed by adjusting the rotational speed of the motor with respect to the rotational speed of the pulley.
