Aircraft chilling system architecture
A chiller assembly for a galley having one or more rectangular galley compartments defined by a back wall, a floor, a top wall and two opposing side walls, the chiller assembly comprising a chiller system comprising a heat exchanger configured to be located in use in a space adjacent a side wall of a compartment external to the compartment, and a blower duct connected to receive chilled air from the heat exchanger, the blower duct arranged to extend adjacent the top wall or the floor of the compartment, the blower duct having vents to blow chilled air into the compartment via the top wall or the floor, the chiller system further comprising a return duct arranged adjacent the other of the floor or the top wall of the compartment to suck air from the compartment and return it to the heat exchanger.
1 . A chiller assembly for a galley defined by straight outer side walls, a top extending from one side to the other and a bottom extending from one side to the other, the galley having one or more rectangular galley compartments therein, each defined by a back wall, a floor, a top wall and two opposing side walls, the chiller assembly comprising a chiller system comprising a heat exchanger configured to be located, in use, in a space adjacent an outer side wall of a galley external to the galley, the space being formed, in use, between a galley outer side wall and a rounded inner surface of a fuselage in which the galley is, in use, located, and a blower duct connected to receive chilled air from the heat exchanger, the blower duct arranged to extend adjacent and across, in the direction from one side wall to the other, the top wall or the floor of one or more compartment, the blower duct having vents to blow chilled air into the compartment via the top wall or the floor, the chiller system further comprising a return duct arranged adjacent and across, in the direction from one outer side wall to the other, the other of the floor or the top wall of the one or more compartment to suck air from the one or more compartment and return it to the heat exchanger, wherein the blower duct is connected to the heat exchanger via a conduit defined by a bend between the heat exchanger and the blower duct.
2 . The chiller assembly of claim 1 , wherein the blower duct extends adjacent the top wall and blows air from the top of the one or more compartment and the return duct sucks air from the bottom of the one or more compartment.
3 . The chiller assembly of claim 1 , wherein the blower duct extends adjacent the floor of the one or more compartment and blows air from the bottom of the compartment and the return duct suck air from the top of the one or more compartment.
4 . The chiller assembly of claim 1 , further comprising a second chiller system comprising a second heat exchanger, a second blower duct and a second return duct.
5 . The chiller assembly of claim 1 , wherein the blower duct is connected, at an end opposite the end connected to the heat exchanger, to a conduit connected to the return duct.
6 . The chiller assembly of claim 4 , wherein the first chiller system is configured to be located, in use, in a space adjacent the side of a lower compartment in a galley and the second chiller system is configured to be located adjacent the back wall of an upper compartment of the galley.
7 . The chiller assembly of claim 1 , where the blower duct is configured to extend adjacent the top wall of multiple adjacent compartments.
8 . A galley defined by straight outer sides, a top extending from one side to the other and a bottom extending from one side to the other, the galley having one or more rectangular galley compartments therein, each defined by a back wall, a floor, a top wall, and two opposing side walls, and the chiller assembly as claimed in claim 4 , the heat exchanger located adjacent and external to an outer side wall of the galley.
9 . The galley of claim 8 , comprising a plurality of lower compartments arranged side-by-side and a plurality of upper compartments arranged above the lower compartments, and a work deck between the lower and the upper compartments.
10 . The galley of claim 9 , wherein the blower duct extends along the work deck.
11 . The galley of claim 8 , wherein the second chiller system is located adjacent the back wall of one of the upper compartments.
12 . The galley of claim 8 , wherein the side wall of an end compartment of the one or more compartments is located adjacent a non-straight inner surface of an aircraft, the space being defined between the side wall and the non-straight inner surface.
13 . An aircraft comprising the galley as claimed in claim 8 .
