Abstract: In accordance with the present invention refrigerant compositions are disclosed. The refrigerant compositions contain comprise 11-28 weight percent difluoromethane; 34-59 weight percent pentafluoroethane; and 21-38 weight percent 2,3,3,3-tetrafluoropropene. The refrigerant compositions are useful in processes to produce cooling, in methods for replacing refrigerant R-404A or R-507A, and in refrigeration systems. These inventive refrigerant compositions can be used in stationary and mobile refrigeration equipment, and are particularly useful for transport refrigeration units.
