Flow pattern and thermal comfort in office environment with active chilled beams

Precision Ventilation in Open-Plan Offices: A Study of Variable Jet Interaction Between Active Chilled Beams

“…In mixing ventilation, thermal uniformity is established in a room by the significant contribution of buoyant forces from the human body, which gets mixed with cold fresh air from the ceiling [61]. Furthermore, heat sources in a room with ACBs also has a significant impact on room air distribution patterns and may increase draught risk [257]. However, in the present study, even with the presence of high air velocity zones created for high heat sources (high metabolic rates) in the same room, the DR for occupants with normal metabolic rates in other zones was within acceptable limits.…”

“…Koskela et al (2012) investigated airflow patterns and thermal comfort in an office environment with ACBs and found out that thermal plumes from heat sources have a notable effect on the velocity distribution in the occupied zone.Melikov et al (2007b) made an experimental study 2. METHODOLOGY The ACB units used in experiments were tested and rated according to DS/EN 15116 European standard (Company, 2008).…”
