Optimum duct design for variable air volume systems. 1. Problem domain analysis of VAV duct systems.

Author(s) : KIM T., SPITLER J. D., DELAHOUSSAYE R. D.

Summary

VAV (variable air volume) systems operate much of the time at an off-peak load condition, and the impact of varying airflow rates to the sizing of duct systems is usually not considered. This and a companion paper introduce 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. In part 1, the domain of a VAV optimization problem is analysed to define the problem characteristics and to suggest an optimization procedure. In part 2, the VAV duct design procedure is fully developed and applied to several VAV duct systems with different parameter values.
