Testing of a hydrocarbon mixture in domestic refrigerators.

Author(s) : JUNG D., KIM C. B., LIM B. H., LEE H. W.

Summary

Performance of a propane/isobutane (R290-R600a) mixture was investigated in domestic refrigerators. Thermodynamic cycle analysis indicated that the R290-R600a mixture in the composition range of 0.2 to 0.6 mass fraction of R290 yields an increase in the COP of 1.7 to 2.4% as compared to R12. The experimental results obtained with the same compressor indicated that the R290-R600a mixture at 0.6 mass fraction of R290 showed a 3 to 4% increase in energy efficiency and a faster cooling rate as compared to R12. The R290-R600a mixture showed a shorter compressor on-time ratio and lower compressor dome temperatures than R12. In conclusion, the proposed hydrocarbon mixture seems to be an appropriate candidate to replace R12 from the viewpoint of energy conservation.
