Manual D Ductsize - Residential HVAC Duct Sizing

The Easiest Duct Sizing Yet

You're not going to believe how easy duct sizing just got. With Manual D Ductsize, yousimply drag and drop a few duct objects onto the Drawing Board drawing window, tell it to

automatically create your runout ducts, and click the Resize menu. The program will thenautomatically assign the CFM values to each duct based on the load calculation results, calculate allthe sizes, redraw all the ducts at their proper width or diameter, and calculate all the pressure losses.Watch the video demo to see this new program in action.

Features

Calculates optimal air conditioning duct sizes.Computes round and rectangular duct sizes.Four sizing methods available: Nearest Inch, Exact, Use Schedule, and Presize.Fitting Selector dialog displays drawings of hundreds of ACCA duct fittings.Both supply and return duct systems can be entered in the same project. Return-side ductsystem losses are automatically accounted for when calculating the supply-side duct system.The number of trunks & runouts is virtually unlimited.Provides comprehensive color reports which can be printed, previewed on screen and saved todisk.Works with high-velocity duct systems as well as conventional systems.Uses either English or metric units.

Requirements

You must have active licenses for both Rhvac and Drawing Board.

Overview

Manual D Ductsize works as a component within Drawing Board and Rhvac to calculate optimum ductsizes. It automatically creates runout ducts in each room of your floor plan and assigns them theproper airflows as calculated by Rhvac. Reports show the static pressure loss of each individual ductas well as the cumulative loss at each point in the system.

Calculation Method

The Manual D Ductsize Program is based on the design procedures given in ACCA's Manual D. Theequal friction sizing method is used to determine optimum duct sizes to the nearest inch orcentimeter. You can also select to size ducts based on a user-defined schedule of sizes, or exact(nearest tenth of an inch, or millimeter). Or you can select Presize for the sizing method and enteryour own diameter or height and width for the duct. Static pressure losses resulting from fittings anddampers are based on Manual D's equivalent length definitions, with the several hundred fittingdefinitions from Manual D built in to the program, including pictures.

Program Input

Inputting data consists of drawing duct objects and setting their properties in the Object Propertieswindow of Drawing Board, as well as with popup dialogs.

Program Output

The reports are integrated with those of Rhvac, so to see a report of the results just check thechecbboxes in the "Manual D Ductsize" frame on Rhvac's Select Reports dialog. New reports will thenbe included in the Print Preview window's list of reports. One reports will show you detailed informationfor each duct followed by a duct system summary that lists key data about the duct system such asthe runout with the highest pressure loss and the duct with the largest calculated diameter. ThePressure Changes Graph report will show you the static and total pressure available at each pointalong the route with the highest static pressure loss.
