❄️ ASHRAE Active Chilled Beams (Induction Ratio 3:1 to 4:1, Nozzle Pressure " WC)

Active Chilled Beam Airflow Calculator

Size active induction chilled beams (Price / Halton / TROX) for commercial office spaces under ASHRAE guidelines: calculate primary ventilation airflow (CFM at 0.4" to 0.8" WC nozzle plenum pressure), calculate induced secondary room airflow (3:1 to 4:1 aerodynamic induction ratio across hydronic cooling coils), total sensible cooling capacity, and HVAC margins.
