The superspreading of covid 19 in closed environments has been an obstacle to the control of the pandemic. This article gives insight into the estimates of the virus concentration inhaled by susceptible people in a closed environment with an air conditioning system that might bring in fresh air and exhaust stale air. The study integrates displacements and interactions in the environment. We implemented a spatio-temporal multi-scale modeling approach that relies on the coupling of an advection-reaction-diffusion equation to describe the viral concentration in the environment and a social forces model to govern agent dis-placement. Three scenarios were discussed: one with an uniform air flow from a ventilation system, one with variable air flow, and one without an air conditioner at all. The effectiveness of non-pharmaceutical interventions in limiting the risk of infection is evaluated for each scenario. According to the findings, the virus concentrations inhaled by susceptible people decreases by 98 %, compared to the scenario where there is no ventilation. Additionally, the results recommend maintaining a social distance inside a closed environment without ventilation systems, and that using masks in combination with a good conditioning system with ventilation improves the effectiveness of mask use.
