What is R416A used for?

A blend of R134a and R124. Used for medium temperature refrigeration or for automotive as a drop in refrigerant.
Is R12 freon?
Because of this, in the early 1930s, a new refrigerant based on a chlorofluorocarbon (CFC), specifically dichlorodifluoromethane, was developed. It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable.

Is there a drop in replacement for R12?
RS-24 is a “Drop-in” alternative for R12 which also provides a long term solution at the same time. It provides, therefore, a one change solution to the replacement of R12 at minimal expense.
What type of oil is used in R 134a and what oils will mix with it?
Polyolester oil (POE oil) is a type of synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A and R-12. HFC-134a with POE oil as the lubricant is a replacement for CFC-12 with mineral oil as the lubricant. as HFC-134a does not mix well with mineral oil.
Is there a direct drop in replacement for R12?
Is R12 still available?
And, as of Jan. 1, worldwide production of R-12 ceased, so the remaining stocks of the refrigerant are limited. That’s one reason for the high cost; the other is a federal “environmental” tax approaching $6 per pound.
