Marineaire, probably the largest player in air conditioning on boats
over 30 feet, currently uses R22. I've seen R134a in refrigeration
units (the Sea Frost we took around the world was R134a), but not in
air con.

Well actually I meant R-12 like my 1992 Mazda uses. I think R-22 is a type
of "freon" used before R134 came around in aviation A/C systems. JC
