Understanding Chilled Beam Systems - Trane
www.trane.comthe primary airflow required for space sensible cooling. A survey of performance data from various chilled beam manufacturers indicates that the typical primary airflow rate for active chilled beams ranges from 0.30 to 0.70 cfm/ft2. This is typically higher than the minimum outdoor airflow required by ASHRAE 62.1-2007 for many applications.
