This is quite confused. Efficiency is a property of a refrigeration
system, not a refrigerant. It also varies with conditions. There is no
such thing as comparative efficiency of refrigerants, as opposed to system
efficiency under specific conditions.

You may be confusing refrigerant properties like molar heat capacity with
efficiency. R410a is "better" in that regard than R22, and worse in other
properties important to refrigeration. Which one performs better depends
on the systems employed and the operating conditions. You can cook up
examples where either outperforms the other.

Kinch,
Your trolling is getting a bit tiresome. Maybe if you got your nose out of
the books, and actually worked with these refrigerants and this equipment in
real life, you would have a better understanding of what we are talking
about.
