Abstract
Systems, apparatus and methods for disinfection of airflow. An apparatus for disinfecting air-conditioned airflow in a confined space includes: a modular housing; and a disinfection chamber enclosed within the housing. The disinfection chamber includes a plurality of disinfection sheets. Each disinfection sheet comprises a plurality of ultraviolet (UV) light sources. The airflow is configured to be routed along a serpentine pathway within the housing to expose microorganisms in the airflow to far UV-C light emitted by the UV light sources for an extended and optimal duration.
Claims4
A process for disinfecting airflow in an airplane, comprising:
- transferring cooled/heated atmospheric air and cabin air to an air mixing unit;
- routing air from the air mixing unit to a HEPA filter for filtration;
- connecting a disinfecting apparatus to the filter, wherein the apparatus comprises:
- a modular housing comprising:
- a disinfecting chamber, wherein the disinfecting chamber includes a plurality of disinfection layers, each disinfection layer comprising a plurality of tubular ultraviolet (UV) light sources;
- directing the filtered air from the filter to the apparatus;
- routing the filtered air along a serpentine pathway over each of the plurality of layers;
- and
- exposing microorganisms in the filtered air to far UV-C/UV-C light emitted by the plurality of tubular ultraviolet (UV) light sources,
- wherein the filtered and disinfected air is routed directly from the disinfecting apparatus to a cabin in the airplane.
