The differences between various types of automotive air conditioning compressors

Automotive air conditioning compressors are primarily classified based on their working principles and structural features:

1.‌Classification by Working Principle‌:

• Fixed Displacement Compressor (CC)‌: The displacement of this type of compressor increases proportionally with the engine speed. It cannot adjust its displacement according to the cooling demand, resulting in a relatively simple structure and lower cost‌

• ‌‌Variable Displacement Compressor (VD)‌: This type of compressor can adjust its displacement based on the cooling demand, providing more flexible and energy-efficient cooling performance. It is more complex in structure and higher in cost compared to fixed displacement compressors‌

2.Classification by Structural Feature‌:

• Reciprocating Compressor‌: This type of compressor uses a crank-connecting rod mechanism to drive the piston for compression. It is characterized by high compression efficiency and wide applicability but may produce more vibration and noise‌

• ‌Rotary Compressor‌: Rotary compressors, such as sliding vane compressors, rolling rotor compressors, and scroll compressors, use rotating components to compress the refrigerant. They are generally more compact, quieter, and have fewer vibration issues compared to reciprocating compressors‌

​

Specifically, some common types of rotary compressors include:

• Sliding Vane Compressor‌: Uses sliding vanes to compress the refrigerant‌

​

• Rolling Rotor Compressor‌: Utilizes a rolling rotor for compression‌

​​

• Scroll Compressor‌: Employs a spiral-shaped scroll to compress the refrigerant, known for its high efficiency and low noise‌

In addition to the above classifications, automotive air conditioning compressors can also be categorized based on their drive modes, such as electromagnetic clutch-driven, direct-driven by an auxiliary engine, or driven by a DC brushless motor or AC motor in the case of electric vehicles‌.

Overall, the choice of compressor type depends on factors such as the specific requirements of the automotive air conditioning system, cost considerations, and energy efficiency requirements.
