| Abstract(E) | Reducing air‑conditioning energy consumption is critical for electric vehicles. With the advent of autonomous driving, the vehicle cabin is increasingly envisioned as a living space, making occupant comfort as important as energy efficiency. In this study, a simplified vehicle cabin model was used to investigate an intermediate AC mode that mixes fresh and recirculated air. The influence of this mode on the cabin airflow field was examined experimentally through stereo PIV visualization. Flow‑field control strategies were evaluated with the aim of improving thermal comfort while minimizing AC energy use. |
