Test results of hydrocarbon mixtures in domestic refrigerators-freezers.

Author(s) : LIU Z., HAIDER I., LIU B. Y., RADERMACHER R.

Summary

An R290/R600 mixture was tested as a drop-in substitute in a 20-cubic-feet, single-evaporator, auto-defrost, topmount, conventional domestic refrigerator-freezer. The capillary tube was lengthened to achieve the optimum performance. The best result with an optimized R290/R600 blend was 6% savings compared to the baseline test with R12. In addition, an 18-cubic-feet, auto-defrost, topmount, domestic refrigerator was used for experiments. Having tested for the single-evaporator baseline performance, the authors converted it to a two-evaporator modified-Lorenz-Meutzner cycle. The optimum performance of the modified unit yielded 14.6 and 16.7% energy savings with binary mixtures R290/n-c5, and R290/R600, respectively. Mixture R290/R600/n-c5 with 17.3% energy savings proved to be better than the binary mixtures.
