A review of different ventilation methods for controlling the transmission of the virus during the COVID-19 pandemic

With the COVID-19 pandemic sweeping worldwide, much attention has been paid to infectious viruses. Because of different sizes pathogen-carrying droplets exhaled by individuals infected with COVID-19, influence gravity and inertia on varies, which leads modes transmission virus. Ventilation changes air distribution in a room, affects virus transmission. An appropriate ventilation method that reduces floating time viruses exposure rate human body should be selected. Although previous studies have extensively reviewed methods reduce airborne viruses, research remain limited. This review aimed explore mode could ensure thermal comfort maintain low infection rates body. study investigated importance particle size. The effects mixing ventilation, displacement impinging jet stratum removal applications at various locations were compared. results this can contribute reducing indoor concentrations during pandemic.
