Abstract
An elevator cab and method of sterilizing the air of an elevator comprising, a plenum configured to fluidly connect to an interior of the elevator cab, at least one intake formed in the side walls of the elevator cab and in fluid communication with the plenum, a fan configured to draw air from the elevator cab via the intake duct and the plenum, and a kill box, including a source of ultraviolet C (UVC) light, and configured to receive air via the fan, wherein the UVC light is configured to sterilize air removed from the elevator cab.
Claims20
An elevator cab comprising:
- at least one intake duct formed in a ceiling of the elevator cab;
- a fan configured to draw air from the elevator cab via the intake duct;
- at least one filter configured to filter the air drawn from the elevator cab by the fan;
- and
- a kill box, including a source of ultraviolet-C (UVC) light, and configured to receive air via the fan, wherein the UVC light is configured to sterilize air removed from the elevator cab.
A kill box comprising:
- a fan in fluid communication with an inlet duct;
- at least one ultraviolet-C (UVC) lamp;
- a first filter positioned between the fan and the UVC lamp,
- a second filter positioned between the UVC lamp and an outlet duct;
- and
- a substantially air-tight housing, configured to receive the first and second filters and the UVC lamp, wherein the filters ensure that air entering the substantially air-tight housing remains within the substantially airtight housing for sufficient time to ensure that particles in the air are sterilized.
A room sterilization system comprising:
- a housing configured to receive at least one filter;
- an ultraviolet-C (UVC) lamp mounted in the housing;
- fan configured to force air through the housing and the at least one filter, wherein the air is exposed to UVC light from the UVC lamp;
- an exhaust duct configured to receive the air from the housing;
- a register in fluid communication with the exhaust duct and configured to expel air into the room;
- a plurality of air inlets in fluid communication with the room;
- a plurality of chase ducts in fluid communication with the air inlets and the fan, such that suction created by the fan draws air from the room through the air inlets and chase ducts and into an inlet side of the fan;
- wherein the at least one filter is configured to ensure the air drawn from the room remains in the housing for sufficient time that any pathogens in the air are sterilized.
