Reports on the design of an HVAC duct system using the dynamic programming method (DPM), which considered system pressure equilibrium and the least life-cycle cost to derive the duct size and fan capacity. The limit on duct diameter or flow velocity was added to the computation process. As a result, the derived outcome satisfied all the requirements of duct diameter or flow velocity. Claimed that the computation needed in DPM is simpler than most methods that consider the least life-cycle cost, making DPM a successful method for duct system design.
