When you conduct an inferential statistical test, you are often comparing two hypotheses: We also offer the following additional apps for the iPhone and iPad:ġ.To understand power, it is helpful to review what inferential statistics test. 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. In addition, we developed a number of customized apps for ASHRAE, DNV GL, and other organizations.

In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. The "HVAC Duct Sizer" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. CSV attachment that can be imported into any popular spreadsheet. This app now works on your iPhone and iPad and adjusts its screen size accordingly.įinally, you can email all of the inputs and results from all 3 input modes to perform further analysis using your desktop computer.
This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. You can also choose to display values in either English (IP) or Metric (SI) units. You can specify additional parameters such as the duct shape (rectangular, round, or oval), the air temperature and the air pressure. 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. 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 "Size by Dimensions" mode, you can analyze an existing duct system. 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 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). Think of this application as a digital version of the classic Trane Ductulator. The Duct Sizer application allows you to quickly size one HVAC duct run or a range of duct sizes using the constant friction method.
"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.
