Front grille of an air conditioner as well as its function to cover the inside of the air conditioner are important components to determine the quality. The draft resistance is determined by this complicated shape. Thanks to the development of Computational Fluid Dynamics (CFD), we have a method to apply CFD to various developments. We studied the porous media for modeling the front grille. Then, we designed a method for analyzing individual draft resistance of the front grille to obtain the relation given to the porous media. Further, we analyzed the influence of design parameters of each front grille upon the draft resistance. Finally, we obtained an ideal shape of the front grille under certain conditions.
