Elite Software Ductsize v6.01.223

Ductsize 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 (using three different sizing methods), or enter your own sizes to analyze an existing design. Or you can do any combination of the two, where you specify the duct sizes through tight areas where there is little room for ductwork, and let the program calculate the sizes everywhere else. 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. Data entry can be accomplished manually or taken graphically from either Drawing Board or Autodesk Building Systems 2006 or 2007, or soon from AutoCAD MEP 2008 . 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 ASHRAE Handbook of Fundamentals and the SMACNA HVAC Systems Duct Design Manual. Important new 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.

Features
-Calculates optimal air conditioning duct sizes.
-Computes round, rectangular, & flat oval duct sizes.
-Four sizing methods available: Static Regain, Equal Friction, Constant Velocity, and As Built ("Presize").
-Links to Autodesk Building Systems 2006 and 2007, and soon with AutoCAD MEP 2008 (Static Regain version only).
-Includes a built-in fan library for noise calculations.
-Fitting Selector displays drawings of over 190 ASHRAE duct fittings, now inclding return fittings.
-Project Explorer provides a tree-style graphical representation of all trunks & runouts in the project.
-Includes Duct Connection Tree Diagram report, a concise, graphical report to give the installer.
-Both supply and return duct systems can be entered in the same project. Return-side duct system losses are automatically accounted for when calculating the supply-side duct system.
-The number of trunks & runouts is virtually unlimited.
-Calculates from manually entered data or directly from duct drawings created with Drawing Board (sold separately).
-Trunks and runouts are each given a user defined name instead of just a number. Trunk and runout names can be changed at any time.
-A virtually unlimited number of separate duct systems can be entered in a single project.
-Provides comprehensive color reports which can be printed, previewed on screen and saved to disk.
-Determines noise levels and required attenuation.
-Reports can optionally be generated as HTML file.
-Reports can optionally be generated as an RTF file (for Microsoft Word) or a PDF file (for Adobe Reader).
-Uses ASHRAE and SMACNA procedures.
-Uses either English or metric units.
-Includes customizable toolbar and menu to fit your work style.
