Automotive HVAC – Cabin comfort

Dr. Schneider’s primary products are visible parts for the car interior: air vents, stowage boxes, kinematic components, bezels, covers and trims, grills and window frames.

The main aspect of Cabin comfort is airflow distribution. Airflow distribution is investigated at a very early stage and must adhere to strict customer targets and specifications. As an example the influence of a bezel was investigated. The two variants of this broadband vent, with and without bezel, were simulated. The broadband vent variant including the bezel shows a better distribution of the airflow. The flow angle into the lower area is enlarged. Additional experiments in the lab using fog to visualize the air flow confirmed the FLOEFD predictions.
