Evaluation of Thermal Comfort for Novel Aircraft Cabin Ventilation Concepts

Flexible cabin layout, high demands on thermal comfort and energy efficiency as well as industrial modular design are the main challenges for aircraft engineers when addressing the ventilation of the aircraft cabin. Nowadays, mixing ventilation is installed in all commercial aircraft, guaranteeing a high degree of mixing and therefore a robust and stable ventilation concept for the cabin [1]. However, complex and weight-intensive ducts are required. In addition, the system provides only limited heat removal efficiency and high velocities are prone to draft on single seats [2]. Addressing these challenges, we are investigating novel ventilation concepts within the ADVENT project - Advanced ventilation techniques for modern long-range passenger aircraft to promote future energy management systems.
