ASHRAE has recently developed a new duct calculator tool that uses the results of ASHRAE Research to provide ASHRAE members with better ways to size/design duct systems - particularly for flexible ducts. This workshop briefly discusses the research behind the new tool and provide demonstrations and examples of how to use it.
1 Research Background for ASHRAE's New Duct Calculator Tool
This presentation summarizes the ASHRAE sponsored research used to develop the new duct calculator tool. This includes a brief description of the experiments that were carried out and the results of those experiments.
2 Demonstration of ASHRAE's New Duct Design Tool
This presentation covers a brief history of flex duct research at LBNL and TAMU. Data is presented illustrating flex duct performance measurements at various compression levels followed by the averaged data that was used for the duct design tool. Illustrations from ducts installed in residential attics is also presented.
