‌Types of Automotive Air Conditioning Compressors‌

1.Reciprocating Compressor‌: Also known as piston compressor, it's one of the earliest and widely used types. It features mature technology, high thermal efficiency, but with more wearing parts and greater maintenance needs‌

2.Rotary Compressor‌: Includes various types such as rolling rotor, triangle rotor, and multi-vane rotary compressors. They are reliable and often used in small refrigeration systems‌

3.Scroll Compressor‌: Considered the fourth-generation compressor, it's characterized by few parts, small size, light weight, high efficiency, and stability, but with higher manufacturing costs‌

4.Variable Displacement Compressor (VD)‌: Adjusts power output automatically based on set temperature. It controls outlet temperature by adjusting compression ratio according to pressure changes in the AC system‌

5.Fixed Displacement Compressor (CC)‌: Its displacement increases proportionally with engine speed. It cannot adjust displacement based on cooling demand and has a greater impact on engine fuel consumption‌

‌Components of Automotive Air Conditioning Compressors‌

• Compressor (Compressor)‌: The core component that compresses low-pressure, low-temperature refrigerant gas into high-pressure, high-temperature gas.

• Condenser (Condenser)‌: Converts high-pressure, high-temperature refrigerant gas into high-pressure, low-temperature liquid, releasing heat.

• Evaporator (Evaporator)‌: Evaporates low-temperature, low-pressure refrigerant liquid, absorbing heat from the surroundings to cool the air.

• Throttling Valve/Expansion Valve (Throttling Valve/Expansion Valve)‌: Controls the flow of refrigerant into the evaporator, reducing pressure and enabling the refrigeration effect.
