Digital Evaluation of Seat-integrated Heating and Ventilation

The performance of seat-integrated heating and ventilation systems is usually evaluated using hardware measurements under controlled conditions. In this article, Daimler describes the development of an evaluation method based on numerical flow simulation and its integration into the process of seat development.
Benefits of Digitization
Seat-integrated Heating and Ventilation (SiHV) Systems in passenger cars significantly augment the thermal comfort provided by the cabin HVAC system. The aim of these systems is to quickly achieve a certain level of comfort in terms of temperatures and airflow. The development process includes determining the optimal configuration of fans, heaters and seat layers. The flow-thermal performance of different configurations is typically evaluated using costly prototypes at the end of every development stage. Therefore, digitalization of these evaluations is highly beneficial in terms of cost, early predictions and effort.
