Abstract:
The present invention relates to a refrigerant composition, including difluoromethane (HFC-32), pentafluoroethane (HFC-125), and trifluoroiodomethane (CF 3 I) for use in a heat exchange system, including air conditioning and refrigeration applications and in particular aspects to the use of such compositions as a replacement of the refrigerant R-410A for heating and cooling applications and to retrofitting heat exchange systems, including systems designed for use with R-410A.

Claim (Index 8):
A method of cooling air in a heat transfer system of the type having an evaporator, a condenser, a compressor and heat transfer composition in the system, the method comprising:\n (i) condensing the refrigerant, wherein said refrigerant consists of:\n from 48% by weight to 51% by weight difluoromethane (HFC-32), \n 11.5% by weight pentafluoroethane (HFC-125), and \n from about 36.5% by weight to about 40.5% by weight trifluoroiodomethane (CF3I), and wherein said refrigerant is non-flammable when tested in accordance with ASTM E681-2009 as required in ASHRAE Standard 34-2013 and described in Appendix B1 to ASHRAE Standard 34-2013; and \n ii) evaporating the composition in the vicinity of body or article to be cooled, wherein the evaporating comprises evaporating the refrigerant at a temperature of from about \u221240\u00b0 C. to about \u221210\u00b0 C.
