About This Item


Full Description

HVAC Duct Sizing and Analysis Software - *Ductsize Static Regain & Equal Friction* Ductsize from Elite Software lets you create a complete duct system from start to finish, and gives you control over every aspect of the design. You can let the program size all the ducts for you or enter your own sizes to analyze an existing design. If you are an engineer or HVAC designer who wants to step up to the ultimate in a duct sizing program, then Ductsize is for you. Ductsize quickly calculates optimal duct sizes using either the static regain, equal friction, or constant velocity method. Duct sizes can be calculated on a round, rectangular, and flat oval basis. Noise levels and required attenuation are printed for each runout duct. A library of fan data for noise calculations is built into the program.

Ductsize allows an unlimited number of duct sections, and is suitable for both constant volume and VAV systems as diversity is accounted for. Ductsize also has an option for specifying duct height and width constraints to control sizes. This feature is also useful for analyzing problems in existing systems where the duct sizes are already specified. Ductsize is based on the design procedures given in the 2007 ASHRAE Handbook - Fundamentals, ASHRAE Duct Fitting Database and the SMACNA HVAC Systems Duct Design Manual. Important features include a Project Explorer and corresponding report that provide a tree-style graphical representation of all trunks and runouts in the project. In addition, both supply and return duct systems can be entered in the same project.

There are two versions of Ductsize The Static Regain and Equal Friction Version and Equal Friction Only. Please see the Related Products tab for more on Equal Friction Only

Some features of Ductsize include:

  • Calculate optimal air conditioning duct sizes
  • Includes a built-in fan library for noise calculations
  • Fitting Selector displays drawings of over 190 ASHRAE duct fittings

System Requirements: Microsoft Windows 1995 or higher
