| Abstract: | Using the distributing parameter method,the simulation analysis of the heat transfer and the flow characteristics of the new refrigerants R134a and R404A was carried out.The results show that under the operating considerations of the refrigerator cars, R404A had better performance than R134a in the heat transfer and the flow characteristics. R404A is one of the most promising refrigerant substitutes as the new refrigerant mixtures using in the middle and low temperatures. |
