ASHRAE 62.1-2004: Designing Dual-Path
ANSI/ASHRAE Standard 62.1-2004, Ventilation for Acceptable Indoor Air Quality, prescribes new minimum breathing zone ventilation rates and a new calculation procedure to find the minimum intake airflow for different ventilation systems. Previous articles discussed the new ventilation design requirements for single-zone, 100% outdoor air, changeover-bypass VAV, and single-path VAV systems.
