Abstract
An airflow sterilizing unit configured to airflow in a heating, ventilation, and air conditioning (HVAC) system is disclosed. The airflow sterilizing unit includes a portion of a duct at least partially lined with an ultraviolet (UV) reflective material, a plurality of hollow structures positioned within the portion of the duct, each comprising an external UV reflective surface, and at least one array of UV light emitting diodes (LEDs) mounted on a surface of at least one of the plurality of hollow structures. The sterilizing unit is configured to replace a section of an existing duct in the HVAC system such that air within the HVAC system passes through the sterilizing unit before exiting from one or more vent.
