Influence of Subjective Cooling Zone Flow Field on Human Comfort Level

Abstract

The flow field produced by subjective cooling conduits for a room at 39oC was studied experimentally and numerically. A typical office room was chosen and temperature measurement was conducted in the subjective cooling site. The numerical simulation was used to estimate the air velocity and distribution throughout the volume under consideration. Depending on the position of the air jets and the horizontal plane, the air velocity through room volume was ranged from 0.1 to a 0.4m/s. More uniform temperatures of 23oC were measured for the case of 0.6m width space. While the temperature variation, through room volume, for the other cases was in the range of 24 to 27oC.
