Description

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 enter either airflow or velocity and the calculator will solve for the other variables including friction (Pressure Loss).

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!

Comfort man ,

Works just like a slide rule.

When using on a system that was sized corectly per ACCA or whatever load calc program your country uses its spot on

Simple to use, precise output, not loaded with useless stuff. Tried a few other apps and always use this App !!
I had a similar app to this years ago. It went out then this one was available ? Looks like an improved version. Anyway keep this App active, it’s a neat one.

Does not do what it leads you to believe.

For $6.99 this app is not worth purchasing. It leads you to believe it will help you solve duct size airflow problems. IMHO, it is not worth purchasing.
