Abstract
We Have Conducted An Experiment To Assure The Effectiveness Of Design Concept Of "Ceiling-Panel Non-Dew Diffuser" In The Sense That. LIt Prevent Dewing On The Surface Of Diffuser As Well As Adjacent Ceiling-Panels By Mixing Cold Air From Diffuser With Warm Air Induced By Its Current From Ceiling Area, And Using Heat Radiation Fins.2.It Also Prevents Unpleasant "Cold Drft" To Human Body. Shape Of The Testing Unit Was Well-Examined Through Flow-Analysis To Be One Of The Most Approprete For This Experiment
