Optimum duct design for variable air volume systems, Part 2: Optimisation of VAV duct systems


Reports, in conjunction with Part 1, on an optimum duct design procedure for VAV systems to investigate the importance of the varying airflows to the system design.  Hourly airflow requirements, part-load fan characteristics, and duct static pressure control are incorporated into the problem formulation.  Constraints, such as discrete duct sizes and velocity limitations, are incorporated into the duct design procedure.  The duct design procedure was applied to several VAV duct systems with different parameter values.  The results were analysed to compare duct design methods, and the effect of several factors that influence optimal design were investigated.
