HVAC Duct Sizer 1.5

Source:Carmel Software Corporation

The HVAC Duct Sizer app is the #1 selling duct sizing application for the Android OS. Hundreds of users have downloaded this useful application for performing quick and simple duct sizing analysis.


The Duct Sizer application allows you to quickly size one HVAC duct run using the constant friction method. Think of this application as a digital version of the classic Trane Ductulator.

In the "Size by Airflow" mode, you can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensions, the equivalent diameter (for rectangular and oval duct) and the calculated velocity and friction loss.

In the "Size by Dimensions" mode, you can analyze an existing duct system. There are options to input the existing duct dimensions and one of either the airflow or velocity values to derive the calculated duct friction loss.

You can specify additional parameters such as the duct shape (rectangular, round, or oval), the duct material type, duct roughness, the air temperature and the air pressure. You can also choose to display values in either English (IP) or Metric (SI) units.

This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results.

REGARDING THE COMMENT BELOW ABOUT INCORRECT CALCULATIONS: IN FACT, THE CALCULATIONS ARE 100% CORRECT. WE HAVE COMPARED IT AGAINST A STANDARD DUCTULATOR AND ALSO OTHER DESKTOP SOFTWARE CALCULATORS. EVERYTHING IS CALCULATING CORRECTLY. PLEASE EMAIL US AT INFO@CARMELSOFT.COM IF YOU HAVE ANY HESITATIONS.

The "HVAC Duct Sizer" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. We currently offer 20+ apps for the iPhone and are converting all of them to the Android OS. In addition, we developed the ASHRAE 62.1 ventilation and Duct Fitting Database iPhone apps that are currently sold by ASHRAE, Inc.
