Experimental studies of the effectiveness of UV irradiation for supply ventilation systems of ship premises

ABSTRACT

The air environment is favorable for the reproduction of microorganisms and viruses. The problem has become particularly urgent in connection with the Cov19 coronavirus pandemic, which undoubtedly affected the operation of all types of fleet. The need for a concealed installation of an air disinfection device is due to safety requirements during the operation of the vessel. The recirculators currently in use are not elements of shipboard ventilation systems. The article proposes the modernization of this system using an integrated air disinfection unit. A schematic diagram of such an installation is proposed. An experimental stand has been developed to determine the effectiveness of air disinfection by studying microbial contamination. The planning and processing of the experiment results were carried out using a software product. A mathematical model has been developed for the operation of the supply air disinfection unit in the ship's ventilation system, which provides the necessary efficiency with minimal energy and heat costs for air treatment.
