| 抄録（英） | This study investigates the cycle performance and system behavior of a novel refrigerant, R474A in the heat pump for new energy vehicles. Results show under both cooling and heating conditions, R474A demonstrated strong performance: a COP up to 3.67 under light-load conditions, a maximum cooling capacity of 7004.5 W, and a maximum heating capacity of 6044.5 W. Comparative analysis revealed that R474A outperforms R134a and R290 in terms of cooling and heating capacity across conventional and extreme operating conditions, while maintaining a higher COP than R290. Notably, R474A overcame the operational limitations of R134a at extreme low temperatures and exhibited minimal temperature non-uniformity from glide effects, ensuring satisfactory thermal comfort. These findings highlight R474A's significant potential as a sustainable alternative refrigerant for NEV heat pump applications. 翻訳 |
