You can easily change the minimum and maximum allowable values for all input parameters.Ĥ. Each fitting has its own custom set of input parameters and results.ģ. You can create individual projects, each with unique input values and results.Ģ. The following is a partial list of features:ġ. The advantages of this mobile app are that you can easily use it out in the field to do quick duct pressure loss calculations, the inputs can be adjusted by touch, and installation is automatic. This app is based upon the popular ASHRAE Duct Fitting Database desktop and web applications. Features include dynamic illustrations of each design, and the ability to share reports and spreadsheets through email. The ASHRAE DFDB app allows you to perform pressure loss calculations for all 240+ ASHRAE duct fittings in both IP and SI units.

However, lack of sufficient up-to-date data makes it difficult to provide a solid basis for those decisions. Engineers depend on accurate owning and operating data to make decisions involving the life cycle and functionality of buildings. The purpose of this database is to provide current information on service life and maintenance costs of typical HVAC equipment. ASHRAE: Service Life and Maintenance Cost Database
