Thermal comfort within a vehicle cabin is of utmost importance for both safety and user satisfaction. This study evaluates the impact two air diffuser geometries—the classical innovative lobbed diffusers—on thermal environment car cabin. Experiments were conducted in an automobile-like enclosure climatic chamber, using Dacia Duster dashboard ventilation system. The system was manually controlled to vary airflow rates. Wireless temperature sensors placed at strategic positions levels (head, chest, knees) monitor variations over six measurement sessions with different configurations. Results show that types effectively maintain uniform distribution across seating levels. However, diffusers demonstrated superior performance by maintaining slightly lower or comparable temperature, despite higher inlet temperature. suggests enhanced mixing capability, leading more consistent cooler environment, particularly advantageous during warmer conditions. highlights optimizing cabins improve passenger comfort. Further research on long-term energy efficiency recommended fully explore benefits diffusers.
