Airflow distribution in rooms with active chilled beams

Impact of the arrangement of the chilled beams and impact of the layout of the work places to air distribution and thermal comfort is important for good projection as well as instalation of chilled beams in the room. This study deals with real layouts of office rooms ventilated with active chilled beams and investigate impact of the heat sources on the flow pattern and consequently on the thermal comfort. Full scale measurements in the test chamber were performed with low velocity thermal anemometers with omni-directional transducers. Thermal manikins and real computers, monitors, lights and heating panels (windows) were used to simulate heat sources. Results show significant differences in single arrangemets of the rooms.
