摘要： Disclosed are refrigerants comprising at least about 97% by weight of a blend of three compounds, said blend consisting of:
from about 38% by weight to about 48% by weight difluoromethane (HFC-32), from about 6% by weight to about 12% by weight pentafluoroethane (HFC-125), from about 33% by weight to about 41% by weight trifluoroiodomethane (CF3I) and from about 2% by weight to about 16% by weight 2,3,3,3-tetrafluoropropene (HFO-1234yf) wherein the percentages are based on the total weight of the three compounds in the blend, and methods and systems which use same.-
