Abstract

MAC accounts for 7% - 20% of the energy consumption and emission of fuel vehicles. However, With the trend of electrification of automobiles, MAC emissions will further increase. In addition, the refrigerant R-134a for MAC is a powerful GHG, and low-GWP alternatives include R-744 and R-1234yf. Evaluating the emission reduction potential of the life cycle of MAC is of great significance to carbon emission reduction. Based on the LCCP, this paper constructs a electric car MAC emission reduction benefit evaluation model, and analyzes the life cycle emission reduction potential and cost of low-GWP refrigerant MAC in different climate regions. The results show that the R-744 system has the largest emission reduction potential in cold climate regions, with a reduction of about 3.7tCO_2eq of single-vehicle emissions, while the R-1234yf system has the largest reduction potential in areas with higher temperatures, and the reduction of single-vehicle emissions is about 1.4tCO_2eq. In addition, the life cycle carbon emission reduction cost of alternative refrigerants can be as low as 300 ¥/tCO_2eq, which has cost advantages compared with other emission reduction technologies.
