Development of Half-Ducted Propeller Fan for Air Conditioners by Using Numerical Optimization with Objective Functions for Improving Fan Efficiency and Aerodynamic Noise

We developed a high-efficiency half-ducted propeller fan to reduce the electric power consumption of the outdoor unit ofa packaged air conditioner by using a design tool combining computational fluid dynamics (CFD) with multi-objectiveoptimization techniques based on a genetic algorithm (GA). The ba...
