Ashrae Duct Fitting Database: 2016 [upd]

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has been a leading authority in the HVAC industry for over a century. One of the most valuable resources provided by ASHRAE is the Duct Fitting Database, which has been a go-to reference for engineers and designers for many years. In this article, we will explore the ASHRAE Duct Fitting Database 2016, its features, and its significance in the HVAC industry.

Unlike simple friction loss charts (which account for straight duct resistance), this database focuses on caused by:

Each fitting is assigned a unique 4-to-6 digit ID, such as (rectangular 90° mitered elbow). The database then provides: ashrae duct fitting database 2016

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has been a leading authority in the HVAC industry for over a century. One of the most valuable resources provided by ASHRAE is the Duct Fitting Database, which is a comprehensive collection of data on the aerodynamic performance of various duct fittings. The 2016 edition of this database is a crucial tool for engineers, architects, and designers involved in HVAC system design. In this article, we will discuss the significance of the ASHRAE Duct Fitting Database 2016 and its applications in the HVAC industry.

For a 250 mm diameter, 90° smooth radius elbow with R/D = 1.5, the engineer enters the airflow and elevation (for density adjustment), and the DFDB returns the appropriate C-value and pressure drop. Unlike simple friction loss charts (which account for

For field use, ASHRAE offers a free DFDB Lite app for iPhone and iPad, allowing pressure loss calculations for select supply, common, and return/exhaust fittings in both I-P and SI units. Inputs can be adjusted by touch, and installation is automatic.

The is a comprehensive technical resource used by HVAC engineers to calculate pressure loss across various duct components. While "2016" often refers to the version compatible with software from that era (like Revit 2016), the database itself is currently available as a cloud-based subscription .

The 2016 version is formally the , released in 2016 (some references call it the 2016 edition). It superseded v4.0 (2009) and was later updated by v6.0 (2020).
