Abstract:
The present invention relates to heat transfer compositions comprising refrigerant, lubricant and stabilizer, wherein the refrigerant comprises about 49% by weight difluoromethane (HFC-32), about 11.5% by weight pentafluoroethane (HFC-125), and about 39.5% by weight trifluoroiodomethane (CF3I), and wherein said lubricant comprises polyol ester (POE) lubricant and/or polyvinyl ether (PVE) lubricant, and wherein said stabilizer comprises an alkylated naphthalene and optionally but preferably an acid depleting moiety.
