Abstract

We compared state of the art mixing ventilation (MV) to a novel ventilation concept based on displacement ventilation (HV). Hereto, we conducted experimental and numerical investigations addressing thermal comfort as well as ventilation and energy efficiency in a generic car mock-up. We considered winter, summer and spring/fall conditions. Concerning the ventilation efficiencies, HV performed comparable or better than MV. Comfort benefits are expected from equivalent temperature measurements for spring/fall and summer conditions. None of the systems was able to provide comfortable conditions in the winter scenario, however, MV revealed the best cooling efficiency, while HV provided the best heating efficiency.
