Suction wing row of the inner unit of an air conditioner as well as its function to cover the inside of the air conditioner are important components to determine the design quality. The draft resistance is determined by this complicated shape. Therefore, with the present development method, a prototype is installed on the main body to obtain an optimum shape by repeating performance of the experimental evaluation.
Thanks to the development of Computational Fluid Dynamics(CFD), we have a method to apply CFD to various developments. In this study, we studied the porous media for modeling the suction wing row. Then, we designed a method for analyzing individual draft resistance of the suction wing row in order to obtain the relation given to the porous media. Further, we analyzed the influence of design parameters of each suction wing row upon the draft resistance. Finally, we obtained an ideal shape of the suction wing row under certain conditions using CFD.
