Characteristics of air flow in climate chamber under natural cross-ventilated environment

Abstract

These measurements were conducted to define the characteristics of air flow in climate chamber 1 of the IEQ Laboratory at the University of Sydney under natural cross ventilation condition in summer season. Thermal anemometers recorded two different heights (600mm and 1100mm) horizontal, two directions (N-S and E-W) vertical distributions and time history of air velocity in this report. The outdoor wind conditions were predominantly easterly during the period of study. The indoor air velocity close to window was higher than near-wall and middle of chamber. It was increased with height in case of near windows, and decreased with height in case of middle of chamber.
