Airborne-mediated diseases like chickenpox, tuberculosis, influenza, influenza, measles, and rhinovirus represent major public health challenges. In the process of examining the causes related to the transmission of infection, studies on the airborne pathogen and the way it spread were carried out mainly in the medical field. In low-middle income countries, studies on the diffusion of air pollutants and virus diffusion in the hospital were limited. Short-wavelength ultraviolet C (UVC) light has an airborne antimicrobial great potential for preventing airborne transmission by inactivating the airborne pathogens. However, its widespread use in public areas is limited because conventional UVC light sources may risk skin cancers and eye damages. To overcome these problems, we propose a novel UVC air disinfection device and utilize the computational fluid dynamics (CFD) method to simulate the dispersion of airborne droplets in a double-bed hospital room. This paper reports the airborne pathogens spreading patterns according to the location of the proposed device. The transient simulation results concerning the airborne pathogen tracing combined with their concentration and distance provided evidence of the contaminant zones that should be checked and cleaned. The effectiveness of the proposed device was confirmed through the airborne pathogen tracing simulation and device's location analyses in a double-bed hospital room. |
