This version introduced several critical additions and technical fixes to improve the accuracy of air distribution modeling: : CD11-4 : Straight Duct, Round, Constant Equal Friction. CD11-3 : Straight Duct, Round, Velocity Limited. CD3-22 & CD3-23 : Flexible elbows with ratios of 1.0 and 1.5, respectively.
: Differentiated by supply, return, or exhaust configurations. Examples of Standard Fittings
