With propane/n-butane blends, energy savings up to 6% were achieved in a domestic refrigerator/freezer compared to the baseline test with R-12. The hydrocarbon mixtures were tested as drop-in substitutes. All the hardware remained the same, only the capillary tube was lengthened to control the flow rate. The additional capillary tube length, the blend concentration, and the charge were adjusted to determine the optimum performance. The best result of 2.29 kWh/day was achieved with a blend of 70% R-290 and 30% R-600, 70 g of charge, and an additional capillary tube length of 5 ft.
