Abstract
Abstract A method and apparatus for distributing air. The apparatus includes an air distribution vent that distributes air into a compartment, wherein the distribution of air into the compartment causes compartment air from the compartment to be drawn from the compartment. The apparatus also includes a contaminant removal system, wherein compartment air drawn from the compartment is processed to remove contaminants before being distributed back into the compartment by the air distribution vent.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
222 words
An aircraft air processing system comprising: a first channel connecting a passenger cabin in an aircraft to a secondary area in the aircraft; a second channel connecting the passenger cabin to the secondary area; an air supply conduit in the secondary area, the air supply conduit having an outlet; a nozzle section between the outlet and the passenger cabin, the nozzle section forming at least one nozzle for directing a first airflow from the outlet through the at least one nozzle into the passenger cabin, the at least one nozzle positioned with respect to the first channel such that the first airflow draws air from the passenger cabin into the secondary area through the second channel and recirculates the air drawn from the passenger cabin into the secondary area back to the passenger cabin through the first channel and through the at least one nozzle to form a second airflow that circulates between the passenger cabin and the secondary area through the first channel and the second channel; and a contaminant removal system in the secondary area and positioned in the second airflow to remove contaminants from the second airflow entering the secondary area from the passenger cabin through the second channel before the second airflow returns to the passenger cabin through the first channel and through the at least one nozzle.
Claim 2
Dependent Claim
222 words
An aircraft air processing system comprising: a first channel connecting a passenger cabin in an aircraft to a secondary area in the aircraft; a second channel connecting the passenger cabin to the secondary area; an air supply conduit in the secondary area, the air supply conduit having an outlet; a nozzle section between the outlet and the passenger cabin, the nozzle section forming at least one nozzle for directing a first airflow from the outlet through the at least one nozzle into the passenger cabin, the at least one nozzle positioned with respect to the first channel such that the first airflow draws air from the passenger cabin into the secondary area through the second channel and recirculates the air drawn from the passenger cabin into the secondary area back to the passenger cabin through the first channel and through the at least one nozzle to form a second airflow that circulates between the passenger cabin and the secondary area through the first channel and the second channel; and a contaminant removal system in the secondary area and positioned in the second airflow to remove contaminants from the second airflow entering the secondary area from the passenger cabin through the second channel before the second airflow returns to the passenger cabin through the first channel and through the at least one nozzle.
Claim 3
Dependent Claim
39 words
The aircraft air processing system of claim 1 , wherein the at least one nozzle is associated with the outlet to cause the second airflow to move in a manner that increases a ventilation rate in the passenger cabin.
Claim 4
Dependent Claim
30 words
The aircraft air processing system of claim 1 , wherein additional use of power is unnecessary to generate the second airflow and to remove the contaminants from the second airflow.
Claim 5
Dependent Claim
17 words
The aircraft air processing system of claim 1 , wherein the contaminant removal system is a filter.
Claim 6
Dependent Claim
19 words
The aircraft air processing system of claim 1 , wherein the contaminant removal system is an ultraviolet light system.
Claim 7
Dependent Claim
19 words
The aircraft air processing system of claim 4 , wherein the filter is a high efficiency particulate air filter.
Claim 8
Dependent Claim
27 words
The aircraft air processing system of claim 4 , wherein the filter is comprised of at least one of foam, pleated paper, charcoal, zeolite, and fiberglass elements.
Claim 9
Dependent Claim
38 words
The aircraft air processing system of claim 4 , wherein the contaminant removal system also includes an ultraviolet light source, wherein the ultraviolet light source destroys bacteria and viruses in the second airflow moving though the secondary area.
Claim 10
Dependent Claim
29 words
The aircraft air processing system of claim 1 , wherein the first airflow causes a low pressure area to occur around the first channel to cause the second airflow.
Claim 11
Dependent Claim
28 words
The aircraft air processing system of claim 1 , wherein the secondary area is located in at least one of a crown and a bay in the aircraft.
Claim 12
Dependent Claim
25 words
The aircraft air processing system of claim 1 , wherein the nozzle section forms a nozzle on each of opposite sides of the nozzle section.
Claim 13
Dependent Claim
30 words
The aircraft air processing system of claim 1 , wherein the first channel and the second channel extends through a ceiling that separates the passenger cabin from the secondary area.
Claim 14
Dependent Claim
53 words
The aircraft air processing system of claim 1 , further comprising at least one porous connector connecting the nozzle section to a ceiling that separates the passenger cabin from the secondary area, the first airflow flowing from the outlet through the at least one porous connector and through the at least one nozzle.
Claim 15
Dependent Claim
24 words
The aircraft air processing system of claim 1 , wherein the first channel and the second channel each comprises a plurality of spaced openings.
