Abstract

A galley system includes a galley compartment defining a cavity. The galley compartment has a door that allows access to the cavity and at least a first opening and a second opening. A galley cart is positionable in the cavity of the galley compartment that has a first opening and a second opening. An air supply duct is configured to be coupled in flow communication with the first opening of the galley cart and the first opening of the galley compartment. A space is defined about the galley cart when the galley cart is positioned in the cavity. The space provides flow communication between the second opening of the galley cart and the second opening of the galley compartment.

First claim

What is claimed is:

1. A galley system comprising:
a galley compartment defining a cavity, the galley compartment comprising a door that allows access to the cavity and at least a first opening and a second opening;
a galley cart positionable in the cavity of the galley compartment, the galley cart having a first opening and a second opening, the first opening of the galley cart being positioned proximate to the first opening of the galley compartment for air-through-cart cooling of the galley cart, and the second opening of the galley cart being positioned remote from the second opening of the galley compartment for air-over-cart cooling of the galley cart;
an air supply duct configured to be coupled in flow communication with the first opening of the galley cart and the first opening of the galley compartment; and
a space defined about the galley cart when the galley cart is positioned in the cavity, the space providing flow communication between the second opening of the galley cart and the second opening of the galley compartment such that air flows from the second opening of the galley cart substantially throughout the space outside of the galley cart and then flows to the second opening of the galley compartment through the space.

2. The galley system of claim 1 , wherein the galley compartment comprises a plurality of walls, the first and second openings being provided in different walls.

3. The galley system of claim 1 , wherein the galley compartment comprises a back wall, a top wall, bottom wall, and a front wall with the door, at least one of the first opening or the second opening is defined in at least one of the top wall or the bottom wall and not in the back wall.

4. The galley system of claim 3 , wherein both the first opening and the second opening are defined in at least one of the top wall or the bottom wall and not in the back wall.

5. The galley system of claim 1 , wherein the galley compartment comprises a back wall opposite the door, the galley compartment including a top half and a bottom half, the air supply duct being routed through the back wall at either the top half or the bottom half, the other of the top half or bottom half being devoid of any air duct.

6. The galley system of claim 1 , wherein the galley compartment comprises a back wall opposite the door having an interior facing the cavity and an exterior facing a passenger compartment, the galley compartment including a top half and a bottom half, the exterior of the back wall along the top half being positioned a first distance from the galley cart, the exterior of the back wall along the bottom half being positioned a second distance from the galley cart different than the first distance.

7. The galley system of claim 1 , wherein the galley compartment comprises a back wall opposite the door, the space having a first width defined between a front of the galley cart and the door, the space having a second width defined between a rear of the galley cart and the back wall, the first width being approximately equal to the second width.

8. The galley system of claim 1 , further comprising an air return duct configured to be coupled in flow communication with the space and the second opening in the galley compartment, the second opening being positioned either above or below the galley cart.

9. The galley system of claim 1 , wherein at least one of the first opening or the second opening in the galley compartment is aligned along a vertical axis with the galley cart.

10. The galley system of claim 1 , further comprising a supply air valve between the first opening of the galley compartment and the first opening of the galley cart.

11. The galley system of claim 10 , wherein the supply air valve is positioned either above or below the galley cart.

12. The galley system of claim 1 , wherein the first opening of the galley compartment, the second opening of the galley compartment and the galley cart are aligned along a vertical axis with the galley cart positioned between the first and second openings.

13. The galley system of claim 1 , wherein the galley compartment comprises a back wall opposite the door having an interior facing the cavity and an exterior facing a passenger compartment, the back wall having a jogged section such that the exterior of the back wall is non-planar.

14. The galley system of claim 13 , wherein the jogged section reduces a width of a corresponding portion of the cavity by at least 5 percent.

15. The galley system of claim 13 , wherein the jogged section increases leg room of a row of seats behind the galley compartment.

16. The galley system of claim 13 , wherein the jogged section increases seat reclining room of a row of seats in front of the galley compartment.

17. The galley system of claim 13 , wherein the jogged section shifts positions of portions of the back wall by at least 3 inches.

18. The galley system of claim 1 , further comprising a second galley compartment, the air supply duct passing above the galley compartment and the second galley compartment.

19. The galley system of claim 1 , further comprising an air return duct configured to be coupled in flow communication with the space and the second opening in the galley compartment, the galley system further comprising a second galley compartment, the air return duct passing above the galley compartment and the second galley compartment.

20. The galley system of claim 1 , wherein the galley compartment comprises an airflow component transition zone, a supply air grille being positioned between the first opening of the galley compartment and the first opening of the galley cart in the airflow component transition zone, the back wall having an interior facing the cavity and an exterior facing a passenger compartment, at least a portion of exterior of the back wall being positioned vertically below the airflow component transition zone such that an exterior environment defining the passenger compartment behind the galley compartment is positioned vertically below the airflow component transition zone.

21. The galley system of claim 1 , wherein the air supply duct is configured to be coupled in flow communication with the galley cart by an air-over-cart supply arrangement.

22. The galley system of claim 1 , wherein the air supply duct is configured to be coupled in flow communication with the galley cart by an air-through-cart supply arrangement.

23. A galley monument for use with a galley cart having a first opening and a second opening, the galley monument comprising:
a galley compartment having a back wall, a top wall, a bottom wall, and a front wall, the front wall having a doorway defined therethrough, the doorway configured to allow the galley cart to be positioned in the galley compartment;
a door coupled to the front wall to close the doorway, wherein the back wall, the top wall, the bottom wall and the door define a cavity configured to receive the galley cart;
an air supply duct configured to be coupled in flow communication with the first opening of the galley cart; and
an air return duct configured to be coupled in flow communication with the second opening of the galley cart;
wherein at least one of the air supply duct or the air return duct is defined in one of the top wall or the bottom wall and not in the back wall of the galley compartment, and
wherein one of the air supply duct or the air return duct is located proximate to at least one of the first and second openings of the gal
