Auto AC Conditioning Compressor For Hyundai Sonata KIA K5 97701-D4400 97701D4400 97701C2000

Core function:

As the "heart" of the air conditioning refrigeration system, it achieves cooling inside the driver's cabin by compressing the refrigerant (R-134a) and making it circulate within the system. Variable displacement compressors can automatically adjust the refrigerant flow rate according to the temperature inside the vehicle, improving refrigeration efficiency and reducing fuel consumption. The refrigeration intensity of the fixed-displacement compressor is controlled by starting and stopping the electromagnetic clutch.

The principle of variable displacement compressors

The piston stroke is automatically adjusted according to the pressure changes in the air conditioning pipeline, eliminating the need for frequent starts and stops, ensuring smoother operation and making it suitable for mid-to-high-end models.
Avoid the power fluctuations of the engine when the fixed-displacement compressor starts and stops, and improve driving comfort.

The principle of a fixed displacement compressor

The working state is controlled by the engagement/disengagement of the electromagnetic clutch. When the temperature of the evaporator reaches the set value, the clutch disengages and the compressor stops running.
