Air Terminal Layout of Stratum Ventilation

This chapter investigates the influence of air terminal layout on the performance of stratum ventilation using a combination of experimental and numerical methods. The experimental findings demonstrate that both the exhaust location and the supply air flow rate significantly impact the air diffusion performance. Simulation results demonstrate that the exhausts at the bottom of the wall in the occupied zone lead to improved air mixing. This configuration contributes to enhanced thermal comfort and indoor air quality. Furthermore, optimal levels of thermal comfort and air quality are achieved when the exhausts are placed at a lower level along the same wall as the supply air outlets, resulting in space savings for installation. Consequently, this particular air terminal layout is preferred for the design of stratum ventilation systems, provided that the performance requirements are met.
