ABSTRACT:
When a hybrid compressor starts being driven by an electric motor, the electric current of a capacity control valve is applied at an initial control electric current SS that is greater than a control electric current S, which is from the state of a refrigerating circuit. This triggers a swash plate of the hybrid compressor to be rapidly inclined. Thereafter, the electric current of the displacement control valve is applied at the control electric current S. This structure enables the displacement of the hybrid compressor to rapidly recover when the hybrid compressor starts being driven by the electric motor.
