Evaluation of Germicidal Ultraviolet Disinfection on HVAC Contaminated Aerosols

Antoine Gaillard et. al. at Van Der Vaal Zeeman Institute write about adding UV-C modules to HVAC systems. Full text PDF at: https://arxiv.org/pdf/2301.09136.pdf AbstractThe COVID-19 pandemic caused a paradigm shift in our way of using heating, ventilation, and air-conditioning (HVAC) systems in buildings. In the early stages of thepandemic, it was indeed advised to reduce the reuse and thus the recirculation of indoor air to minimize the risk of contamination through inhalation of virus-laden aerosolparticles emitted by humans when coughing, sneezing, speaking or breathing. However,such recommendations are not compatible with energy saving requirements stemmingfrom climate change and energy price…
