The ASHRAE Duct Fitting Database is a digital repository of loss coefficients (C-values) for thousands of duct fittings. It is the electronic companion to the ASHRAE Handbook—Fundamentals and the HVAC Duct Construction Standards . Before this database, engineers relied on printed tables and manual interpolation—a time-consuming and error-prone process.
In Excel, go to File > Options > Add-ins > Manage COM Add-ins . Manually add the ASHRAE_DuctDB.xla file from the installation directory. The database will launch a configuration wizard to
Legacy or cracked versions do not receive critical updates or bug fixes. Using outdated pressure loss coefficients can lead to calculation errors, resulting in undersized fans, poor airflow, and system inefficiencies in real-world HVAC installations. 3. Intellectual Property and Legal Compliance
