About HVAC Duct Sizer
HVAC Duct Sizer voted favorite mobile app by readers of Contracting Business magazine.
The HVAC Duct Sizer app is the #1 selling duct sizing application for the Apple iPhone and iPad. Tens of thousands of happy users have downloaded this useful application for performing quick and simple duct sizing analysis.
The HVAC Duct Sizer is a universal duct sizing app so that it works on both the iPhone and iPad and adjusts its screen size accordingly.
This app includes the HVAC Equipment Locator. Click here for details: http://bit.ly/1BPl1Nr
Just a couple of comments from our users:
"I'll be presenting your iPhone program to my HVAC class as an easy compact tool to have in hand when making sales and service calls." - R. Black
"I like this app and use it daily" - V. Joe
The Duct Sizer application allows you to quickly size one HVAC duct run or a range of duct sizes 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 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.
In the "Range of Duct Sizes" mode, you can specify minimum and maximum friction loss and airflow values to display a range of duct sizes that fall in between the friction loss bounds.
You can specify additional parameters such as the duct shape (rectangular, round, or oval), 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.
This app now works on your iPhone and iPad and adjusts its screen size accordingly.
Finally, you can email all of the inputs and results from all 3 input modes to perform further analysis using your desktop computer. The email includes HTML text and a .CSV attachment that can be imported into any popular spreadsheet.
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. In addition, we developed a number of customized apps for ASHRAE, DNV GL, and other organizations.
This app now includes the HVAC Equipment Locator which allows you to keep track of all of your equipment and store it in the cloud. Click here for details: http://bit.ly/1yTq539

1. Now compatible with iPod touch 1st generation
2. User can specify not to include digit group separator (i.e. - comma separator - 1,000 ). This is most appropriate for international users of this application where in many instances a comma is never used.

1. Updated launch icon
2. Minor user interface updates
3. Now works with 2nd generation iPod Touch
3. The user can now increase/decrease all inputs by customized values. For example, as the user slides the air flow slider control to the left or right, the amount it increases/decreases can be customized to say, 100 CFM, or any value the user desires. The same applies to friction, duct dimensions, and velocity inputs.

1. The aspect ratio input is now located on the main input form along with an accompanying slider control so you can instantly change the aspect ratio for given airflow and velocity/friction loss inputs so as to easily view all the resulting duct dimensions.
2. The equivalent duct diameter for rectangular and oval shaped duct is displayed with the other calculated results
3. In the "Size by Dimensions" mode, the user can now toggle between inputting an airflow or velocity value in addition to the duct dimension values
4. A couple of additional duct material types have been added along with the accompanying roughness factors
5. Includes the ability to display alternative metric units such as millimeters instead of centimeters for duct dimensions and Pa/m instead of Pa/30m for duct friction loss
6. The user interface has been slightly updated
