Developed for Apple’s iPhone, iPod touch, and iPad, the ASHRAE Duct Fitting Database (DFDB) app allows users to perform pressure loss calculations for more than 200 HVAC duct fittings in both I-P and SI units.
The app ensures that engineers in the field have instant access to the most accurate information without having to return to their office to perform calculations. According to ASHRAE, the app features dynamic illustrations of each design, allows for easy use on the job to do quick duct pressure loss calculations and the inputs can be adjusted by touch. Installation is automatic.
Other features of the DFDB app are:
• Users can create individual projects, each with unique input values and results.
• Each fitting has its own custom set of input parameters and results.
• Users can easily change the minimum and maximum allowable values for all input parameters.
• Users can display and e-mail two types of reports, which include a spreadsheet attachment that can be opened on a desktop computer to do further analysis.
The DFDB app is the second mobile app to be released by ASHRAE. The Society published the 62.1 app in the winter of 2010.
The ASHRAE DFDB app can be purchased through Apple’s online iPhone App Store for $19.99. This initial release of the ASHRAE DFDB app includes supply and common round fittings only, though subsequent versions including all of the remaining fittings will be released monthly. Those who purchase the app now will receive these updates as free upgrades.
The app was developed for ASHRAE by Carmel Software Corp., a firm specializing in the development of engineering and scientific mobile and tablet software applications.
