Frequently, it is assumed that the use of a duct calculator or duct wheel is the same thing as a ManualD duct design. This is not a quality alternative to implementing a full ManualD calculation. Many people even know about Manual D, which describes how to design the duct system.
Not so many, however, know about the missing links Manual S and Manual T. If you want a properly designed HVAC system, you have to go through the whole process in all four protocols: J, S, T, and D. The Manual D is a complete schematic drawing of the duct system including locations and sizes of trunklines, branch ducts, outlet registers, an inlet grilles. Manual D: Duct Design Manual T: Air Distribution Manual B: Testing, Adjusting& Balancing Installation best practices Capacity and performance testing HVAC design is a process of discovery.

For residential air duct designs ACCAs Manual D is the procedure recognized by the American National Standards Institute (ANSI) and spe HVAC System Design The Sequential Process for Calculating Loads, Sizing Appliances& Designing ManualD sizing duct systems ManualT termination deviceslocations. design and continuous low speed fan operation can minimize this. Achieving proper duct design can be accomplished by following ACCA Manual J and ACCA Manual D procedures.
Residential Duct Systems for New and Retrofit Homes. Difference between duct design sizing (Manual D) Residential Duct Systems for New and Retrofit Homes Design and Installation for Energy Efficiency and Quality Author: Brian Holton, Ferris State University Below is a simple model for determining duct sizes.
The model applies to system up to 60 feet from unit to register. Because of the complexity of designing duct systems, we highly recommend using the ACCA" Manual D" for sizing ductwork, or consulting a professional HVAC contractor.
