The Influence of Indoor Obstacles on General Ventilation Designs

Y.L. Wu and C.W. Chen

Some real environmental aspects didn’t consider in those methods or standards, such as the obstacles inside the indoor environments. Therefore, a series ventilation experimental design for the kind of environments is conducted in this study. A full scale test chamber was used for tracer gas experiments. Horizontal and vertical board-obstacles are designed for simulation the real environments. Both board-obstacles increase the heights from floor to ceiling. Total of sixteen different arrangements are examined; eight for board-obstacle vertical to the flow path and another eight for horizontal to the flow path. In addition, two different air supply rates will use to investigate the effect of air supply rate on contaminant removal efficiency. The CO2 was used as the tracer gas and decay method was adopted to measure the CO2 concentration of each individual sample point. Four CO2 record trees were installed in the test chamber and each tree has two sample points. Finally, a weight factor for the obstacle’s surface to chamber vertical surface or horizontal surface had found in this study help for evaluating the actual ventilation efficiency or contaminant removal efficiency.
