[Working principle of automotive air conditioning compressor] :
The air conditioning compressor compresses the refrigerant gas to convert it into high temperature and high pressure gas, and then dissipates heat through the condenser to become high temperature and high pressure liquid, and finally decompresses through the expansion valve to achieve the cooling effect.
【 How to identify the quality of products 】 :
1. Observe the appearance: the appearance process is fine, no obvious damage or deformation.
2. Test the cooling effect: test the cooling effect and operation stability of the product after installation.
