is not a "fun" piece of software, but it is an essential professional tool. It bridges the gap between the static data in the ASHRAE Handbook and the dynamic inputs of modern design.
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.
The ASHRAE Duct Fitting Database is a software tool that contains a vast library of duct fittings, including elbows, tees, wyes, and transitions, among others. The database provides detailed information on the pressure drop and airflow characteristics of each fitting, allowing engineers to accurately calculate the performance of duct systems. This information is crucial for designing efficient and effective HVAC systems that meet the required airflow and pressure specifications. ashrae duct fitting database version. 6.00.05
The ASHRAE Duct Fitting Database is a specialized software application that contains loss coefficient data for more than 200 round, rectangular, and flat oval duct fittings. Instead of relying on generalized or outdated friction charts, the database utilizes experimental data compiled by ASHRAE research projects. The Role of Loss Coefficients ( Cocap C sub o

Version 6.00.05 provides the exact empirical data required to size fans optimally, matching the true static pressure requirements of the system. Energy Efficiency and Building Code Compliance
The ASHRAE Duct Fitting Database, version 6.00.05, offers numerous benefits for HVAC designers and engineers, including: CD11-3 : Straight Duct, Round, Velocity Limited
Determine if the fitting belongs to a supply (diverging flow), return (converging flow), or exhaust system.
