The ANSI-recognized national standard for residential HVAC duct design will help you design a duct system in less time. The popular and accurate procedure has been revised to include updated and expanded VAV guidance, with detailed examples; impacts of excess length, sag and compression in flexible ducts; and new equivalent length values for flex duct junction boxes. Manual D, from the Air Conditioning Contractors of America (ACCA), provides a single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials.

The newly released Manual D has been significantly revised to include:
-Updated and expanded VAV guidance, with detailed examples.
-Impacts of excess length, sag and compression in flexible ducts.
-New equivalent length values for flex duct junction boxes.

Manual D provides:
-A single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials
-System operating point (supply Cfm and external static pressure), and airway sizing for single-speed and multi-speed (ECM) blowers
-A method for determining the impact of duct friction and fitting pressure drop on blower performance and air delivery
-The most comprehensive equivalent length data ever published.

You can apply the Manual D procedure to constant volume systems and zoned variable air volume systems, over a full range of duct construction materials. 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; and commissioning issues).

Title: Best option
Review: Version 2.5, just what I needed for school. Brank new, not even dented corners. Much easier and cheaper than buying at my school's bookstore.

Title: reference reading material
Review: This manual is a must for contractors who design and install residential HVAC systems. I worked with a duct design firm when I built my house and referred to this manual. Unfortunately, most contractors don't use software (or even long hand calculations) to design duct systems...they estimate based upon past installations and by using square footage measurements only. While this is faster, it usually means your HVAC system is oversized or undersized and will not provide the expected comfort under a wide variety of conditions. Extra time spent in properly designing your HVAC system will reward the occupants with a more confortable living / working space.

Title: Amazon sells this book for a good bit less than ACCA
Review: Hank - Bless Him - wrote the books on ACCA cooling calculations, duct design, etc. Amazon sells this book for a good bit less than ACCA.Buy it and learn the "Standard of Care" for flexible duct, fitting equivalent lengths ("EL") and the multipliers to be applied for flexible duct workmanship; there're also graphs for flexible duct and lined or fibrous glass friction (NO - You can't use a metal duct Ductulator to size those!).

Title: hello
Review: Funny its a text book.... It was required reading for the test I was taking, so how could it not meet my expectations for I had know choice. Please email someone else Mr. Amazon, oh yes so you know, I could have purchased from anywhere and will next time. Thanks
