Yep, stick your fingers in your ears and say NaaaaNaaaaNaaaa....... I Can't Hear you.......
The Google search terms were [Refrigeration Design Freon], and you know what, the preponderance of the links came back using the term Freon generically, as in offering Freon Compressors, and design expertise in "Freon and Ammonia based refrigeration", and so on. Bottom line : On one hand I have your unsupported assertion that *NOBODY* in the "Industry" would ever use FREON in place of R-12 or dichlordiflouromethane. Conversely I have provided 25 cites ( and that was just the tip of the iceberg) showing common use of the term Freon for cfc based refrigerants. Appeals to authority are not a valid argument technique, especially when the authority is yourself.
Yep, the same mechanism disburses freon in the atmosphere :-)
Ok, so I lift it a few feet. Then what? Will it magically fall again? What prevents some portion of that which a fan lifted a couple of feet from being further lifted by a breeze outside? You can't have your argument both ways.
