“…These methods should pay attention to the emission source and the ventilation condition or the air flow which greatly influence the dispersion [13]. The examples of improvement are by setting the high of exhaust fan [14], setting the direction of jet fan flow [15], setting the variation of on/off operated mechanical ventilation [16], etc. The design should consider the minimum air velocity because the concentration of air pollutant could concentrate at the lowvelocity location [17].…”

Nowadays, lack of space in city center has forced the architects a propose a vertical construction to provide public facility, including the parking garage. Generally, this vertical parking garage has enclosed environment condition, which could be constructed under the building or in the middle of other buildings. This environment causes the parking garage will not have an adequate fresh air circulation or air change rate and gives a more risk due to the accumulation of air pollutants which is emitted from the cars inside. In this research, it observes a simple enclosed parking garage which normally can accommodate six cars. The air pollutant, particularly Carbon Monoxide (CO), from three gasoline cars is extracted by an exhaust fan in a proper location. Two location of exhaust fan are proposed to investigate better air circulation and better air pollutant extraction from the parking garage. The first option (Position of A) installs the exhaust fan near to the parking space units and the other installs the exhaust fan near to the pathway. Each option will follow two worst condition of simulations which are predicted will give a significant impact to Indoor Air Quality (IAQ). Each simulation has to extract the emission from three idle cars with same rate of air circulation of six air change per hour. The results show the influence of air flow pattern to the dispersion of air pollutant. An adequate air flow near to the emission source will cause the increase the maximum of air pollutant concentration. On the other hand, it can minimize the spread of air pollutant dispersion.

“…The jet fan ventilation system has been developed to ventilate underground car parks for carbon monoxide (CO) removal during normal conditions as well as smoke extraction in an emergency scenario, such as a fire. 10–13 Under normal conditions, jet fans can spread the sneeze-originated respiratory droplets in the airflow direction and increase the risk of viral transmission. In this regard, the number of people in underground car parks and jet fans’ velocity play a key role in the risk of viral transmission.…”

Jet fans are increasingly preferred over traditional ducted systems as a means of ventilating pollutants in large environments such as underground car parks. The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)—which causes the novel coronavirus disease—through the jet fans in underground car parks has been considered a matter of key concern. A quantitative understanding of the propagation of respiratory droplets/particles/aerosols containing the virus is important. However, to date, studies have yet to demonstrate viral (e.g., SARS-CoV-2) transmission in underground car parks equipped with jet fans. In this paper, numerical simulation has been performed to assess the effects of jet fans on the spreading of viruses inside underground car parks.
