Aerosol Particle Spreading in an Operation Room under Dynamic Condition Open
We report on the experimental investigation of aerosol particle spreading in an operation room. Different configurations regarding the source position or representative movements of the staff in the room are analyzed. The data acquisition …
Multi-jet personalized ventilation in passenger trains: Objective and subjective thermal comfort Open
Installing local, demand-controlled ventilation – a specific version of a personalized environmental control system – offers great potential in terms of improving the individual thermal comfort and energy savings of the overall train air-c…
Hybrid Train Ventilation Systems for Summer and Winter Conditions Open
The HVAC system of a train is the second largest energy consumer during a train journey, requiring up to 20-30% of the total energy demand. Therefore, new technologies, such as heat pumps or demand-oriented ventilation have been tested and…
Comparison of local equivalent temperatures and subjective thermal comfort ratings with regard to passenger comfort in a train compartment Open
Two methods for assessing thermal passenger comfort are analysed and compared to each other in terms of different ventilation concepts and different inflow air temperatures in a generic train laboratory. The studied ventilation systems com…
