WelcomeWelcome to the electronic spreadsheet version for the ACCAManual D, 3rd Edition (D3) -- Residential Duct Systems, 2008A thorough understanding of the D3 manual as well as a working knowledge of MicrosoftExcel are prerequisites for using this spreadsheet.This spreadsheet uses revised versions of the printed D3 worksheets.Use the printed D3 manual for guidance to enter information into the Effective Length,Friction Rate and Duct Sizing tabs.Microsoft Excel version 97 is the minimum requirement to use the spreadsheet but MicrosoftExcel version 2000 or greater is recommended to utilize the full features of the spreadsheet.We strongly suggest that you print out and read the instructions on using this electronic spreadsheetthat are contained in the following Help tab.This spreadsheet can be downloaded from the ACCA System Design website.ACCA System DesignPlease visit the website often to check for updates to the spreadsheet. The most recent versionnumber is listed on Notes tab.

HelpACCA Manual D, 3rd Edition*** Refer to the Notes Tab to verify the latest revision ***Help SectionRefer to Manual D Residential Duct Systems, Third Edition Version 1.xxStep 1:Go to the Effective Length Tab and enter up to 4 supply runs to determine the longest equivilent run in the system.Enter the linear feet of trunk and runout ducts in the length sections for the supply ducts.Click on the Group Code and find the equivilent feet for all fittings used in the selected supply runs.The program will automatically select the "Total Equivilent Feet" to be used in the Friction Rate Tab.Repeat the steps above for the return ducts.Step 2:Go to the Friction Rate Tab and enter the "External Static Pressure" and "CFM" for the selected equipment.Next enter "Component Pressure Losses" for all components and accesories external of the fan unit.The program will automatically calculate the "Design Friction Rate" value to be used for Duct Sizing.Step 2:Go to the Duct Sizing 1 Tab and enter the heating and cooling BTUH for each supply run.There is a maximum of 14 supply runs per unit.For larger rooms divide the BTUH by the number of runs required for proper distribution of airflow.The program will automatically select the duct size for round metal ductwork.For rectangular metal ductwork enter the height and the program will automatically select the duct size.If Flex Duct is used refer to the Equivilent Flex column to select the correct duct size.Under the supply truck section, select the associated supply runs for this supply trunk section and the CFM willautomatically calculate.The program will automatically select the duct size for round metal ductwork.For rectangular metal ductwork enter the height and the program will automatically select the duct size.If Flex Duct is used refer to the Equivilent Flex column to select the correct duct size.If more than four (4) supply trunk sections are required select the Duct Sizing 2 Tab.Repeat the steps above for the return ducts.
