Abstract:
A non-flammable refrigerant mixture is disclosed. The non-flammable refrigerant mixture consists essentially of (a) from 20 weight percent to 25.5 weight percent HFO-1234yf, (b) from 20 weight percent to 24.5 weight percent HFC-32, (c) from 24.5 weight percent to 30 weight percent HFC-125 (d) from 25.5 weight percent to 30 weight percent HFC-134a, and (e) from about 0.0001 weight percent to 10 weight percent trans-HFO-1234ze. These refrigerant mixtures are useful as components in compositions also containing non-refrigerant components (e.g. lubricants), in processes to produce cooling, in methods for replacing refrigerant R-404A or R-507, and in refrigeration apparatus.
