In air conditioning systems, comfort and energy conservation are important quality indicators for customers and society. To improve these quality items, we focused on the air guide vanes placed at the air outlet of an air conditioning system and studied techniques for controllillg the airflow. The ideal function of the guide vanes was defined in terms of the airflow vector (velocity and flow angle), and the cross-sectional shape of the guide vanes was used as a control factor. The velocity distribution near the guide vanes was calculated by computational fluid dynamics (CFD) and a nominal-is-best parameter design was carried out in two steps. As a result, a technique for designing guide vane shapes with high reproducibility and tunability was developed.
