Overhead cooling device reducing thermal stratification at displacement ventilation

Abstract

We presented a new patent-pending [DE102019122963A1] technology brick for an enhanced cooling and ventilation concept for a passenger aircraft cabin. The new device helps to reduce the thermal stratification of displacement ventilation while maintaining the benefits. At the conference, we will discuss the new approach of the “radiant cooling” device with regard to effects on the temperature and velocity distributions as well as on comfort evaluation parameter such as PMV and PPD within the cabin based on computational fluid dynamics. Furthermore, we will point out possible technical realisations. The experimental validation with a thermally active demonstrator unit will be conducted during the ADVENT project in the modular cabin mock-up (MKG) located at the DLR site in Göttingen.
