The database supports both I-P (inch-pound) and SI (metric) units and includes table data for supply, exhaust, and common (supply/return) duct functions. Modern versions feature an integrated database with fully available input, output, calculations, and table data properties, along with easily viewable calculations that update in real time.

At its core, the DFDB is a digital catalog of loss coefficient (C or K) values for standard HVAC duct fittings, including elbows, tees, transitions, and more. It's an essential tool for engineers calculating pressure drop in air distribution systems. The database supports both I-P (inch-pound) and SI

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) is a renowned organization that provides guidelines and standards for the heating, ventilation, and air conditioning (HVAC) industry. One of the most valuable resources offered by ASHRAE is the Duct Fitting Database, a comprehensive collection of duct fitting data used to calculate the pressure drop in duct systems. In this article, we will discuss the ASHRAE Duct Fitting Database PDF Patched, its significance, and how to access and utilize this valuable resource.
Proper duct design is the backbone of building energy efficiency. By using verified data, you ensure that your HVAC systems perform as intended, saving energy and maintaining occupant comfort for years to come.
The most current data is available via a yearly subscription.
