Is Automobile Refrigerant Freon?

[AnthonyLynn]

Many automobile air conditioning refrigerants are Freon, but some vehicles use non-Freon refrigerants, which should be determined based on the vehicle type. 1. Freon, also known as Fluorine, originates from the English word Freon, a refrigerant trademark registered by DuPont in the United States. In China, there is a divergence in the definition of Freon, generally defined as the collective term for halogen derivatives of saturated hydrocarbons (mainly methane, ethane, and propane). According to this definition, Freon can be categorized into four types: CFC, HCFC, HFC, etc. Some scholars define Freon as CFC refrigerants; in some materials, Freon specifically refers to dichlorodifluoromethane. 2. At room temperature, Freon appears as colorless gases or volatile liquids, odorless or slightly odorous, non-toxic or low-toxic, with stable chemical properties.
