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