FIELD: chemistry.
SUBSTANCE: present invention relates to a refrigerant composition containing difluoromethane (HFC-32), pentafluoroethane (HFC-125), and trifluoroiodomethane (CF3I) for use in a heat exchange system including air conditioning and refrigeration systems, and in particular to aspects of the use of such compositions as a replacement for the R-410A refrigerant in heating and cooling systems as well as for modernization of heat exchange systems including systems designed for use with the R-410A refrigerant.
EFFECT: invention makes the work of heat exchange systems more effective.
