Abstract

Today, the most commonly used refrigerants for refrigeration systems such as refrigerators, freezers - coolers and car air conditioners are refrigerants such as R600a, R404A and R134a. In this content, we mainly calculate and analyze the characteristics of the above refrigerants used in the refrigeration system when there is sub-cooling, calculate and compare the sub-cooling coefficient COP, specific cooling capacity qsub, and cooling capacity. consumed when there is sub-cooling. Specifically, when the sub-cooling degree increases, the COP coefficient of the three media increases, the specific cooling capacity increases but the work does not change. When the sub-cooling level increases to 200C, the R404A refrigerant increases the fastest, with an average increase of 1.48%. From this result we see the effectiveness when we sub-cooling the refrigeration system.
