Modern building energy codes place strict limits on Fan System Brake Horsepower (BHP). Because fan power is directly proportional to total static pressure, lowering duct pressure drops is essential for compliance. Utilizing the precise data in Version 6.00.05 prevents conservative "over-guesstimate" safety factors, allowing engineers to specify smaller, more efficient fans.

The version 6.00.05 is a comprehensive tool designed to help HVAC engineers and designers calculate pressure loss across a wide variety of duct fittings. Version 6.00.05, released as a single-user product, introduced several critical updates to round and flexible duct fittings, as well as range increases for common input parameters. Key Features of Version 6.00.05

The engineering core of the ASHRAE Duct Fitting Database revolves around fluid dynamics calculations inside closed conduits. When air moves through an HVAC system, it encounters friction from straight duct walls and localized turbulence caused by directional changes, expansions, or contractions.

To the uninitiated, a version number like "60005" looks like a random string. To an HVAC engineer, it represents the "source of truth"—the definitive library of how air behaves when it hits a wall, turns a corner, or splits in two.

Enter geometric parameters such as duct width, height, diameter, angle of turns, and turning vane details.
