Speaking of "fluorine-free" refrigerators, people often think that this kind of refrigerator does not use fluorine.

Because fluorine refrigerators use Freon 11 and Freon 12 for foaming agents and refrigerants for refrigerators. However, experts from the China Consumer Protection Foundation pointed out that it can be seen from the chemical reaction formula that the culprit of destroying the ozone layer is "chlorine" and not "fluorine".

What are the two refrigerants, HCFC and HFC, in the fluorine-free refrigerator system?

China translates CFC as fluorine-free. This may be due to this reason. The earliest company’s Freon became synonymous with refrigerant, and the Chinese refrigerant was called Freon. Refrigerators add fluorine and refrigerant. From this point of view, In the past, there was no professional knowledge to introduce it accordingly, so everyone introduced this product name to China as a synonym for refrigerant. Our country's intellectual property and trademark rights are not particularly obvious. The name is so misleading. Even though the Chinese make so many refrigerants, they still say they are fluorine-free. In fact, the clearest word is that CFC should be said to be chlorinated hydrocarbons or chlorofluorocarbons.
