Classification and Adaptation Guide for Automotive Air Conditioning Compressors | Yixiang Auto Parts Selection Tips

In the automotive air conditioning system, the compressor can be called the "heart" component, and its performance directly determines the cooling efficiency and stability of the air conditioning. As a supplier deeply involved in the field of automotive parts foreign trade, Guangzhou Yixiang Automotive Parts Co., Ltd. supplies a full range of automotive air conditioning compressors, suitable for various vehicle models such as passenger cars, commercial vehicles, and new energy vehicles, to meet the technical standards and procurement needs of different global markets.

At present, the automotive air conditioning compressors on the market can be mainly divided into two dimensions: structural type and driving mode. Different types of compressors have significant differences in adaptation scenarios and performance characteristics.

1、 Divided by structural type: each of the three mainstream compressors has its own emphasis

1. Piston compressor
This is a more traditional type of compressor that compresses refrigerant through the reciprocating motion of the piston. Its advantages are mature technology, low cost, and strong cooling power, while its disadvantages are relatively high operating noise and slightly larger volume.
Adaptation scenarios: mostly used for commercial vehicles such as trucks and buses, as well as some old passenger cars.
2. Vortex compressor
Relying on the meshing motion of the moving scroll and the stationary scroll to compress refrigerant, it has the characteristics of small volume, low noise, smooth operation, and high energy efficiency, and is currently the mainstream choice for passenger cars.
Adaptation scenarios: The vast majority of household sedans, SUVs, MPVs, and other passenger cars.
3. Rotary compressor
Compression is achieved through the rotational motion of the rotor, with a simple and compact structure, light weight, low energy consumption, and minimal impact on engine load during start-up.
Adaptation scenarios: auxiliary cooling systems for small passenger cars, micro cars, and some hybrid models.

2、 Divided by driving mode: the core difference between fixed displacement and variable displacement

1. Fixed displacement compressor
The displacement of the compressor is fixed and the working state is controlled by the engagement and disengagement of the electromagnetic clutch. When the set temperature is reached, the clutch disengages and the compressor stops working; After the temperature rises, the clutch engages and the compressor restarts.
Adaptation scenarios: economical passenger vehicles, commercial vehicles, with the advantages of low cost and easy maintenance; The disadvantage is that the refrigeration temperature fluctuates slightly, and there will be a slight jerking sensation when starting and stopping.
2. Variable displacement compressor
Without the need for an electromagnetic clutch, the displacement can be changed by adjusting the angle of the internal inclined plate, achieving continuously variable cooling. It can adjust the cooling power in real time according to the temperature requirements inside the car, running smoother, more energy-efficient, and with lower noise.
Adaptation scenarios: Mid to high end passenger cars and new energy vehicles are the current development trend of automotive air conditioning compressors.

3、 Yixiang selection suggestion: Accurately match vehicle model requirements

1. Selection of passenger cars: Priority should be given to vortex type variable displacement compressors, which balance quietness, energy saving, and cooling stability; Economy models can choose piston type fixed displacement compressors to control procurement costs.
2. Selection of commercial vehicles: It is recommended to use high displacement piston compressors for trucks and buses to meet the rapid cooling needs of large spaces; Small commercial vehicles can be adapted to rotary compressors.
3. Selection of new energy vehicles: A dedicated electric compressor is required, which does not require engine drive. The new energy compressor supplied by Yixiang supports high-voltage DC power supply and is suitable for pure electric and hybrid vehicle models, with the characteristics of high efficiency, energy saving, and silent operation.
