Version. 6.00.05 | Ashrae Duct Fitting Database

Version 6.00.05 represents a reliable iteration of this essential software tool. This article covers everything you need to know about Version 6.00.05, its core features, and how it optimizes HVAC engineering workflows. What is the ASHRAE Duct Fitting Database?

The primary function of Version 6.00.05 is to quantify the energy losses that occur as air moves through various duct components. Straight ducts exhibit friction losses, but significant pressure drops occur at fittings—where the air changes direction (elbows), changes size (transitions), or enters/exits equipment.

Version 6.00.05 includes over , up from approximately 450 in version 5.x. New additions include: ashrae duct fitting database version. 6.00.05

Includes round straight duct options for velocity-limited and equal friction designs, and new flexible elbow variants ( Extended Input Ranges:

) derived from decades of laboratory testing. Designers use these precise values rather than broad estimates to select optimal fan sizes and ensure balanced airflow throughout a commercial or residential building. Key Features of Version 6.00.05 The primary function of Version 6
