摘要：

Upper-room ultraviolet germicidal (UR-UVGI) fixture has been recommended as one of choices for preventing the transmission of the airborne pathogens in poor ventilated room. To theoretically predict the irradiance of multiple UR-UVGI fixtures is key importance for the practical evaluation of their disinfection efficiencies. In this study, a mathematical model based on the view factor approach from radiative heat transfer was developed to predict the irradiance of multiple UR-UVGI fixtures. In the model, the reflector and tedious fixture were simplified as a fictitious surface and the shading effect of the louvers was considered. The model was validated by the literature experiment case. It should be instrumental for the design of the UR-UVGI disinfection system.
