Warning! Do not mix! R-22 and R-410 they are chemically incompatible and use different oils as well. R-22 uses a mineral oil, and R-410 uses an ester oil, if they mix it will cause a foam and sludge that will destroy both the condenser and evaporator.
it would be R-22.. brand new units will have the new refrigerant and that is R-410
The refrigerant used is R-12, R-22, or R-410. You cannot mix refrigerants and you cannot purchase it without an EPA certification card.
R-22 refrigerant is depleting ozone. It is because it is a CFC.

If you are referring to automotive refrigerant, the answer is no. Neither refrigerant will work properly if mixed and might damage the compressor or other components.
R-22
you need to recover all of the refrigerant out of the system with a recovery machine then flush the lines replace filter dryier and if possible txv valve then pull a good vacum to .5 microns then refill with 410 a
"Freon" is DuPont's trademark for its CFC refrigerant products. R-22 is one of those refrigerants, so R-22 and Freon-22 are the same refrigerant.
never mix these freons together---- very dangerous
you will die if you drink it. Nahh you'll probably get very ill though.
