Mcquay Duct Sizer Software Free Download [2021] -
The (now part of the Daikin Applied Design Tools Suite ) is a lightweight, industry-standard program used by HVAC engineers to calculate the physical dimensions of air ducts. This software simplifies complex calculations for air flow, friction loss, and velocity, ensuring HVAC systems run efficiently. Key Features of McQuay Duct Sizer
: Just input two parameters (like CFM and head loss), and the software automatically calculates flow area, fluid velocity, Reynolds number, and friction factor.
The physical cardboard wheel used by engineers for decades has been mcquay duct sizer software free download
: Specify temperature and relative humidity within the software tabs to ensure density-corrected results.
: Seamlessly toggle between Imperial (US standard) and SI (metric) units. The (now part of the Daikin Applied Design
The software outputs the precise dimensions required to maintain that friction rate.
The McQuay Duct Sizer often included features to calculate the pressure drop through fittings. By selecting elbows, transitions, or take-offs, the software would calculate the "Equivalent Length" of straight duct, adding to the total static pressure requirement. This feature is vital for fan selection. The physical cardboard wheel used by engineers for
This is the most critical warning for anyone searching for a free download. Because the software is not available on an official app store or the Daikin website, users often turn to third-party "freeware" repositories or file-hosting sites (like Mediafire, rapidshare, or generic HVAC forums).
This has led to a fragmented landscape of third-party download sites. While the software is free, you must be careful where you get it.
Always verify your design with local building codes (IMC, UMC, or SMACNA standards), but for pure sizing math, McQuay Duct Sizer remains unbeaten.
