Description

In this chapter, system design and calculation of a system’sfrictional and dynamic resistance (total pressure) to airflow are considered.Chapter 19 of the 2020 ASHRAEHandbook—HVAC Systems and Equipment examines duct construction and presentsconstruction standards for residential, commercial, and industrial HVAC andexhaust systems. For design guidance specific to residential systems, refer toManual D by ACCA (1994).
