Résumé

The performances of a refrigeration cycle of a HFC-152a/HFC-125 mixture used as a refrigerant for household refrigerators were calculated and analyzed in detail. The results of the theoretical analysis indicate that the HFC-152a/HFC-125 mixture in the composition of 0.85 mass fraction of HFC-152a has a similar refrigeration performance with the existing refrigerant CFC-12. The experimental results indicate that the refrigeration performances of the domestic refrigerator charged with the new refrigerant can meet the requirement of the National Standard of China, under the appropriate proportion and the optimum charge amount. In conclusion, the mixing refrigerant HFC-152a/HFC-125 proposed in this study seems to be an appropriate long term candidate to replace CFC-12 as a new generation refrigerant of domestic refrigerators, because of its well environmentally acceptable properties and its favourable refrigeration performances.
