Experimental Models for the determination of the Length of the Adjacent Zone for Displacement Ventilation diffusers
A common problem in room equipped with displacement ventilation is the thermal discomfort due to draft, caused by the excessive air velocity at floor level. While displacement
ventilation has been used for decades, no model, neither theoretical nor experimental, exists to predict the length of the adjacent draft zone. Based on the study of detailed
experimental data of 7diffusers (each tested with several outlet sizes), this study proposes two correlation models to predict the length of the adjacent zone.
