Abstract
A system for disinfecting an enclosed space includes a housing, ultraviolet (UV) emitters, a sensor to detect occupancy in or entry into an enclosed space, a UV directing mechanism, and a controller. The housing includes an air flow passageway. When the UV directing mechanism is in the closed state, the UV emitters are positioned in the air flow passageway and transmission of UV electromagnetic radiation into the enclosed space is substantially blocked. UV electromagnetic radiation is transmitted into the enclosed space when the UV directing mechanism is in the at least one open state. Disinfection operations can be activated when the UV directing mechanism is in the open state or the closed state. When the UV directing mechanism is in the open state, the disinfection operation is activated when the sensor indicates no occupancy in or no entry into the enclosed space.
