Which freon will leak from a smaller hole R-22 or R-410A?
The R-22 (chlorodifluoromethane), will leak from a smaller hole
than R-410A will. Sort of. Now that we've answered the question,
it's time to state that R-410A is an azeotropic mixture of
difluoromethane and pentafluoroethane. And the difluoromethane
component of the mixture is a smaller molecule than
chlorodifluoromethane, which is what R-22 is. But the
pentafluoroethane is a larger molecule than the
chlorodifluoromethane (R-22). If molecular size is the sole
determinate as to which "stuff" can get out, part of the R-410A can
get out a smaller hole than the R-22, but all of the R-22 can get
out through the "right sized hole" because it is smaller than a
constituent of the R-410A. It's your call. Links are provided.
