Abstract:

Enclosed germicidal irradiators, known as recirculators, have become widely used for air sanitation over the last years. The article presents the studies of the most common design of the device in terms of implementation of its target functionality. In the course of practical work, the role of shape and UV - C optical properties of material of the irradiation chamber walls for formation of efficient germicidal radiant flux inside it was studied. The significant effect of multiple reflections on the target functionality of the device was substantiated by calculations and confirmed by the test results.
The article proposes the design of the irradiator and the analytical expressions for calculation of the irradiating chamber reflecting surface profile shape providing beneficial conditions for formation of an increased efficient germicidal flux inside it by means of multiple reflections.
