What Does Fluorine-Free Refrigerant Mean for Cars?
1 Answers
Fluorine-free refrigerant refers to an environmentally friendly refrigerant that does not contain Freon. Below are specific details about fluorine-free refrigerants for cars: 1. Overview: Fluorine-free refrigerants are not truly "fluorine-free" but instead use environmentally friendly refrigerants containing fluorine elements. These are typically mixed refrigerants that do not contain chlorofluorocarbons (CFCs). They are composed of two or more different refrigerants mixed in specific proportions. Under certain pressures, fluorine-free refrigerants can maintain a constant evaporation temperature, with their gaseous or liquid phases always retaining the same composition ratio. However, their thermodynamic properties differ from those of the substances before mixing. Azeotropic mixtures can be used to improve the characteristics of traditional refrigerants. 2. Classification: Common fluorine-free refrigerants include R600a, R-134a, R-404A, and R-410A.
