They compared the results of using low pressure, medium pressure, and high pressure ductwork, and found that low pressure and medium pressure ductwork were the most efficient and cost-effective options. They also found that using ASHRAE DFDB helped them reduce the uncertainty and variability in their calculations, and improve the accuracy and consistency of their results. - In a blog post by SimScale , the authors used ASHRAE DFDB and online CFD simulation to optimize the duct design for a fume extraction system in a welding workshop. They used ASHRAE DFDB to select the appropriate duct fittings and calculate the pressure loss for each fitting. They then used SimScale to simulate the airflow and fume distribution in the system, and evaluate the performance and safety of the system. They found that using ASHRAE DFDB and SimScale helped them achieve a balanced and efficient duct design that met the ventilation requirements and minimized the exposure to toxic fumes. - In a technical paper by AIRAH , the authors used ASHRAE DFDB to analyze the impact of the Section J energy efficiency provisions on duct design in Australia. They compared the results of using different methods for calculating the pressure loss in duct fittings, such as loss coefficient tables, equivalent length data, or leakage coefficients. They found that using ASHRAE DFDB helped them comply with the Section J provisions and improve the energy efficiency of their duct systems. They also found that using ASHRAE DFDB opened an opportunity for ductwork component designs to be improved and innovation to occur in the area of duct design. These examples and case studies show how you can use ASHRAE DFDB to optimize your duct design for different types of projects and applications.
