Study on vent spacing of multi-vent module-based adaptive ventilation for reducing contaminant diffusion

Infectious respiratory diseases are known to have high levels of airborne transmissibility. However, traditional ventilation methods based on perfect mixing often lead the diffusion pathogens. Multi-vent module-based adaptive (MAV) is a method designed meet needs different indoor scenes and reduce air mixing. MAV combines multiple groups multi-vent modules. The vent spacing single module also an important factor, but influence change effect in contaminant control has not been studied. Computational Fluid Dynamics (CFD) applied study simple office. Three 1.5m, 2.0m 2.5m four layout modes selected. results show that when distance 2.0m, system best diffusion. Up 61.5% contaminants limited area.
