Abstract
The present invention relates to a refrigerant composition, including trifluoroiodomethane (CF3I); 1,3,3,3-tetrafluoropropene (HFO-1234ze); difluoromethane (HFC-32), and pentafluoroethane (HFC-125) for use in a heat exchange system, including refrigeration applications and in particular aspects to the use of such compositions as a replacement of the refrigerant R-22 or R-404A for heating and cooling applications and to retrofitting heat exchange systems, including systems designed for use with R-22 or R-404A.
