Air purification devices methods and systems

摘要

A device and method for air purification used in cooling, heating and air ventilation systems. The device has at least one UV light source positioned on an inside portion of a movable access panel so that it moves with the access panel from a first position where the UV source directs UV light towards the inside of the system to purify the air stream inside and to remove contaminants from the surfaces inside the system, to a second position where the UV source directs UV light towards the space surrounding the system so that it purifies the air in the room where the system is mounted.

主权项

1. A combined cooling, heating and air supply treatment system for a suspended ceiling installation, comprising:
a housing including an air treatment device and a movable access member which is configured to form an enclosure with the housing when in a first position and to allow access to the air treatment device when in a second position; wherein the access member includes a plurality of openings configured to permit passage of ambient air from a space outside of the enclosure into the enclosure, and passage of air treated by the air treatment device from the enclosure to the space outside of it; wherein the access member is movable from the first position to the second position by pivotal movement; at least one ultraviolet light source attached to an inside portion of the access member, such that the UV light source moves with the access member, said ultraviolet light source generating light in the 240-280 nm range at intensities sufficient to kill microbial contaminants on surfaces and such that direct exposure to people is harmful.
