How much refrigerant should be added to a Volkswagen Phaeton?

[MacCatherine]

The Volkswagen Phaeton generally requires four to six cans of refrigerant. Overview of refrigerant: Refrigerant, commonly known as Freon, is a working fluid used in refrigeration and air conditioning systems to transfer heat energy and produce cooling effects. It can be classified by working method into primary refrigerant and secondary refrigerant. By material properties, it can be divided into natural refrigerant and synthetic refrigerant. Function of refrigerant: In refrigeration and air conditioning systems, refrigerant is used to transfer heat energy and produce cooling effects. Refrigerant is an intermediate substance in the refrigeration process that first absorbs the cooling capacity of the refrigerant to lower its temperature and then cools other substances to be cooled. Caution is required when using refrigerant.
