Abstract

This study assesses the performance of a displacement ventilation (DV) system in the baggage reclaim area of an airport under hot, arid conditions, utilising computational fluid dynamics (CFD). The analysis focuses on thermal comfort, guided by the ISO 7730 and ASHRAE 55-2023 standards. Results show that the DV system effectively supplies cold air throughout the area, with an average temperature of 20.7°C at 1.1 m above the floor, achieving comfort class B and satisfying over 90% of occupants. Localised discomfort was observed near outlets due to high draughts, particularly at floor level and in regions close to multiple diffusers, where air velocities exceeded recommended thresholds. Vertical temperature gradients were maintained within 3 K/m, meeting comfort class B requirements. These findings offer valuable insights into the operational performance of DV systems, highlighting areas for improvement, such as diffuser placement and design, to enhance occupant comfort in similar large-scale spaces.
