Ashrae duct fitting database pdf

Use this mobile app in the field for quick duct pressure loss calculations. The inputs can be adjusted by touch, and installation is automatic. Best of all, they are entirely free to fin use and downloa so there is no cost or stress at all.

PDF may not make exciting reading, but ashrae duct fitting database is packed with valuable instructions, information and warnings. The fittings are numbered (coded) as shown in Table 4. Duct ,Elbow,transitio,drop pressure in every piece. The English unit most commonly used to describe pressure in a duct system is the inch of water gauge (inch wg).

One pound per square inch ( psi ), the standard measure of atmospheric pressure , equals approximately 27. Static Pressure Static pressure is a measure of the static energy of the air flowing in a duct system. THIS APP IS ALSO COMPATIBLE WITH THE LATEST VERSIONS OF IPHONE AND IPAD (and iOS). This database , available on C includes loss coefficient tables for more than 2roun rectangular, and flat oval duct fittings.

Featuring pictorial outlines of each fitting , this CD is useful to design engineers dealing with a variety of duct fittings. as PDF File (. pdf ), Text File (.txt) or read online for free. The list of known supported file types is further down the page. Clicking a file type you need help opening will in most cases find several other programs that can open. The data are reprinted in this manual as a source of information for design engineers. McGill AirFlow Corporation assumes no responsibility for the performance of duct system components installed in the field.

Virus-free and 1 clean download. This add-in provides a way to view the illustrations and the data table of available duct fittings from the database. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files. This annual subscription includes cloud-based access to a database of loss coefficient tables for more than 2roun rectangular, and flat oval duct fittings.

Our team participated in the competition and won first prize. Fitting losses are to be reported as local loss coefficients. The standard does not, however, cover the interpretation of test data. The conference highlighted key technologies and processes that allow scientists, designers, engineers, manufacturers and other decision makers in cold climate regions to achieve good indoor environmental quality (IEQ) with a minimum use of energy and other resources.

To start system design, a maximum velocity is selected for the root section ( duct section downstream of a fan). When energy cost is high and installed ductwork cost is low, a lower initial velocity is more economical. For low energy cost and high duct cost, a higher velocity is more economical.
