Standard 120-2017 -Method of Testing the Determine Flow Resistance of HVAC Ducts and FittingsĪSHRAE Standard 120 establishes uniform methods of laboratory testing of HVAC ducts and fittings to determine their resistance to airflow. Purchase this product from iTunes for $9.99 Learn More The inputs can be adjusted by touch, and installation is automatic. Use this mobile app in the field for quick duct pressure loss calculations. Get the App for your iPhone, iPod, or iPadĪSHRAE Duct Fitting Database (DFDB) for the iPhone, iPod touch, and iPad allows you to perform pressure loss calculations for ASHRAE duct fittings in both I-P and SI units. Purchasers receive a one-year subscription for cloud-based access to the ASHRAE Duct Fitting Database ver. The database interface features fully available input, output, calculations, and table data properties and easily viewable calculations that update in real time. Fittings may be saved into a project file, which is easily navigated and can be stored and transferred. The product includes table data for supply, exhaust, and common (supply/return) duct functions. For any given fitting, enter the flow rate and fitting information and obtain loss coefficient data and associated pressure loss. The ASHRAE Duct Fitting Database, with cloud-based access by annual subscription, includes loss coefficient tables for more than 200 round, rectangular, and flat oval duct fittings.įeaturing pictorial outlines of each fitting, this database is useful to design engineers dealing with a variety of duct fittings.
