Nonflammable mixed refrigerants (MR) for use with very low temperature throttle-cycle refrigeration systems

Refrigerants containing HCFC's are replaced with new blends by using R-236fa and R-125, or R-125 with R-245fa, or R-236ea, or R-134a with R-236fa in place of HCFC's. No hardware or oil composition changes are required to maintain temperatures, pressures and capacity substantially unchanged...
