Abstract

We performed numerical analyses on the optimal discharge angle of a 4-way cassette air conditioner,which is mounted on the ceiling of the classroom, by using thermal comfort and ventilation indices. Weanalyzed the effective draft temperature, the local mean age and the local mean residual life time withrespect to the variation of the air discharge angle of the air conditioner in all occupied zone. Air diffusionperformance index, local supply effectiveness and local exhaust effectiveness were used to investigate theoptimal value of air discharge angle. From the results, we found out that the optimal discharge angle of theair conditioner is about 40 degrees in the present model.
