    Abstract: The present invention relates to a refrigerant composition comprising at least about 98.5% by weight of the following three compounds, with each compound being present in the following relative percentages: 33.0% to 45% by weight difluoromethane (HFC-32);
    48.5% to 67.0% by weight of 2,3,3,3-tetrafluoropropene (HFO-1234yf); and
    1.0% to 6.0% by weight fluoroethane (HFC-161), and to the use of the refrigerant in a heat exchange system, including air conditioning, refrigeration applications and heat pump applications and to the use of such compositions as a replacement of the refrigerant R-410A or R-32 or R-454B for heating and cooling applications.
