How Many ACCA Load Calculation and Design Manuals Are There?
In 1986, ACCA (Air Conditioning Contractors of America) released their Manual J [ANSI/ACCA 2 Manual J - 2016] load calculation format for residential HVAC applications. It was a success that started a trend for future standard calculation and design manuals. There is a Manual D [ANSI/ACCA 1 Manual D - 2016] for residential duct design. Manual N for commercial load calculations and Manual Q for commercial duct design (low velocity and low pressure design). For air and hydronic balancing and testing there is a Manual B. A Manual Zr [ANSI/ACCA 11 Manual ZR - 2021] for residential zoning systems. A Manual T for air distribution fundamentals. For residential equipment selection use Manual S [ANSI/ACCA 3 Manual S - 2014]. This is different from a Manual RS which covers special design steps and principles to install residential HVAC systems for today's homeowner. Commercial systems selection would be Manual CS. There is a Manual H for heat pump systems. A Manual P for psychrometrics (relative humidity and moisture). There is one for HVAC design for swimming pools and spas: Manual SPS [ANSI/ACCA 10 Manual SPS - 2011 (RA 2017)]. Many manuals are compliant with American National Standards Institute (ANSI) standards and national building codes. ACCA produces other quality books and design materials. They are a great asset to the HVACR industry and their website can be found here.
Turn to Design Master HVAC for your complete HVAC design and drafting solution. It adds intelligence to your ductwork layout.
Duct Design Software
Your typical design workflow probably looks something like this: you draft your ductwork in one program, then enter data into one or more additional programs to calculate duct sizing, load calculations, etc. If something needs to be changed, you then need to account for that change in your drafting and in each program.
With Design Master, everything is integrated into the drafting process. A duct centerline isn’t just a line anymore; elevations, sizing criteria, double line settings, fittings, and connections to diffusers are tracked and accounted for. If you make a change, any affected callouts, calculations, and duct sizes are updated.
Design Master Provides Intelligent Diffusers
Design Master gives you intelligent diffusers that connect to your ductwork and respond to adjustments in CFM ranges. You can set the CFM at the diffuser and use it to size your ductwork and measure pressure loss. Design Master’s diffuser schedules let you define all of your diffusers and transfer them between projects.
Design Master Offers Customization
Each engineering firm has its own conventions for duct design and drafting. That’s why Design Master lets you control how your diffusers and callouts look, which fittings are used when drafting ductwork, and more. Set up your customization once and it will be used in future projects, which means less time spent on drafting details and more time spent on the design.
