How to determine refrigerant type.
(OP)
Can anyone tell me if there is any way to determine the type of refrigerant being used in a split, 5 ton residential A/C system?
Thanks in advance for any help.

Thanks.

This suggests that it is the most plausible and possibly the only approach to problem.
Consider the corollary: how could anyone determine the composition of a resistor by simply measuring current and power?

This should narrow things down to a few choices.
If the system isn't contaminated with non-condensible gas, or it hasn't been topped off with something other than what is supposed to be there.

Without taking ANY measurements there is a 95% chance (random # I picked) that the system is R22. If it isn't it is R410a. If it is not those two than you have something that may exist but is definitely an oddball.
Look at the compressor model#. For Copeland scrolls if the model starts ZP you have R-410a.
If you are just curious as to what you have in your home it is easiest to look up model#'s and the like. Assuming the refrigerant in there is what is supposed to be there. I guess that is one reason you would want to know.
Maybe you should tell us what you are trying to do.

If is a very informative site. Everyone is helpful and professional, no flame wars. Alt.hvac is a waste of time.
Good luck!
