Duct Calculator Elite vs HVAC Duct Sizer Usage & Stats

Duct Calculator Elite™ is an industry leading tool designed to simplify the job of duct sizing for HVAC professionals. This app allows users to calculate duct size, velocity, pressure drop, and flow rate for ductwork. Duct Calculator Elite™ features a highly intuitive interface which allows users to easily enter values with precision (without the use of cumbersome "slider" controls). In "Duct Size by Airflow" mode, the calculator allows users set airflow and either velocity or friction (Pressure Loss) and the calculator solves for round and rectangular duct dimensions. Aspect ratio of the rectangular duct can also be specified. In "Duct Size by Dimension" mode, users can enter either a round duct diameter or rectangular duct height and width. In addition, users can lock airflow, velocity, or friction and solve for the other variables. In "Pressure Drop" mode, users can convert between duct length, pressure drop, and friction values. This allows users to quickly determine exact pressure drop of a given installation or calculate the max duct length that can be used to maintain desired pressure drop. This feature compliments the two duct sizing calculators. Duct Calculator Elite™ provides users with a wide variety of preference setting including: -Duct Dimensional Units (Inches, Centimeters, or Millimeters) -Airflow Units (Cubic Feet per Minute, Cubic Feet per Second, Cubic Meters per Second, or Liters per Second) -Velocity Units (Feet per Second, Feet per Minute, or Meters per Second) -Pressure Loss Units (Inches of Water per 100ft or Pascals per Meter) -Duct Material (Aluminum, Concrete, Fibrous Glass Duct Liner, Flexible Duct-Metallic, Galvanized Steel, PVC Plastic Pipe, Smooth Liner, Spiral Steel, or Uncoated Carbon Steel) -Air Temperature (Fahrenheit, Celsius, or Kelvin) -Elevation (Feet or Meters) The Duct Calculator Elite™ solver uses friction loss equations contained in 2009 ASHRAE Handbook - Fundamentals. The next time you go to a meeting or out to the field, leave your Ductulator at home, you'll have everything you need right on your iPhone/iPad/iPod Touch! If you are not 100% satisfied with this calculator please email us at techsupport@cyberprodigy.com so we can make things right before posting any negative reviews. We read all emails. We are also open to any suggestions you may have for future enhancements to this app.

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.

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.
