The Easiest Duct Sizing Yet
Acca Manual D Free Download
ACCA Manuals J, S, and D are referenced and required across America. This form provides a quick and easy review the HVAC system design. This review gives an objective indication whether required processes were followed. Manual J Load Calculations: Estimates are correct for the amount of heating and cooling required for a residence. If software is not listed on this page, then it is not ACCA-approved, and it does not produce results in compliance with our rigorous standards. Especially in terms of Manual J® residential load calculation, make sure that you only use ACCA-approved software in order to ensure compliance with building codes. An Introduction to ACCA Manual S. For many years some professional HVAC businesses have believed that residential HVAC equipment selection was performed following guidance in ACCA Manual J. For example, a home with a 30,000 Btu/h cooling load would use a 2.5 ton air conditioner. ACCA provides free training spreadsheets, known as Speed-Sheets, for use with some of our technical manuals. ACCA also provides a number of educational opportunities related to our manuals, including an online certificate program in residential design and an online certificate program in light commercial design.

You're not going to believe how easy duct sizing just got. With Graphic Manual D Ductsize, you simply 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 then automatically assign the CFM values to each duct based on the load calculation results, calculate all the 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.
Acca Manual D.pdf - Free download Ebook, Handbook, Textbook, User Guide PDF files on the internet quickly and easily. Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues;.
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 duct system 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 to disk.
- 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
Graphic Manual D Ductsize works as a component within Drawing Board and Rhvac to calculate optimum duct sizes. It automatically creates runout ducts in each room of your floor plan and assigns them the proper airflows as calculated by Rhvac. Reports show the static pressure loss of each individual duct as well as the cumulative loss at each point in the system.
Calculation Method
The Graphic Manual D Ductsize component is based on the design procedures given in ACCA's Manual D. The equal friction sizing method is used to determine optimum duct sizes to the nearest inch or centimeter. 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 enter your own diameter or height and width for the duct. Static pressure losses resulting from fittings and dampers are based on Manual D's equivalent length definitions, with the several hundred fitting definitions from Manual D built in to the program, including pictures.

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