Experimental research on dimethylether as a refrigerant for a domestic refrigerator.

Author(s) : HE M. G., LI T. C., ZHANG Y., et al.

Summary

The performances of a refrigeration cycle using dimethylether (DME) as a refrigerant for domestic refrigerator were theoretically calculated and analyzed. The result of the theoretical analysis indicates that DME yields an increase of up to 8.8 and 8.3% in the COP as compared with R-12 and R-134a, and its volumetric capacity is almost equal to those of R-12 and R-134a. The main refrigeration performances of a commercial refrigerator using DME to be the drop-in substitute of R-12 were experimentally examined. The results show that the performances of the domestic refrigerator using DME and R-12 respectively are nearly the same, and the optimum charge amount of DME in the experimental refrigerator is about 54 g; in addition, its energy consumption is 1.087 kWh/day which is only 84.4 percent of that of R-12. The refrigeration performances of the domestic refrigerator charged with DME as a "drop-in refrigerant" could basically meet the requirements of the National Standard of China.
