A STUDY ON THE AIR DISTRIBUTION OF DISPLACEMENT COOLING FOR THEATRE SEATING OUTLETS

摘要

The flow design of the air chamber is a key factor so to achieve even air distribution for the air outlets under the audience seating.The general applications of this type of air- conditioning systems are such as theatres or performance centers.The design of the air flow distribution in the air chamber under the seating has a large impact on the displacement cooling.This study has found that a stagnant layer can be indentified by air velocity of 0.15m/s.This study developed a simple method to verify whether an air stagnant layer exists by using equal-velocity contours that appear in both air inlet and air outlet zones.It has been shown that the existence of an air stagnant layer will ensure air outlet uniformity.
