The system is used for storing and delivering individual food trays having opposite hot and cold food products areas. The housing includes two separate chambers that can receive food trays through a respective one among two opposite lateral openings. Among other things, from the standpoint of an attendant at a food tray assembly station, this system allows using the same left-right food tray orientation regardless of which one of the lateral openings is directly set in front of the standpoint after repositioning the whole housing.

Autonomous trolleys include an integrated power source, which energy can be utilized for integrated trolley systems such as a wheel assist module, heating module, and cooling module. The power source may include a fuel cell system or a rechargeable electrical energy storage device or a combination thereof. The rechargeable electrical energy storage device can be charged by any other power source, including a fuel cell system. The trolley can also be equipped with a fuel tank for easy and safe refueling of a fuel cell system.

A galley cooling system suitable for use in an aircraft comprising a cooling unit adapted to provide a cooling fluid. The trolley compartment of the galley cooling system comprises a front side access opening, a back wall arranged opposite to the front side access opening and two sidewalls. A cooling fluid inlet is provided in the region of a first sidewall of the trolley compartment, the cooling fluid inlet being connected to the cooling unit so as to supply cooling fluid provided by the cooling unit to the trolley compartment. A cooling fluid outlet is provided in the region of the first sidewall of the trolley compartment, the cooling fluid outlet being adapted to discharge cooling fluid heated upon circulating through the trolley compartment from the trolley compartment.

A galley includes a cart compartment defining a cavity configured to store at least one galley cart. The galley includes a heat exchanger positioned within the cart compartment and a plenum coupled in flow communication with the heat exchanger. The plenum is configured to provide cool air to cool the at least one galley cart.

A chiller galley cart includes a plurality of walls defining an interior cavity, a supply valve defined in one wall of the plurality of walls, and a return valve defined in one wall of the plurality of walls. The supply valve and the return valve are configured to couple to a chiller positioned in the interior cavity to provide cooled airflow from the chiller galley cart. A method for cooling a demand galley cart positioned in a cart compartment of a galley includes positioning a chiller galley cart in the cart compartment having a chiller positioned in the interior cavity coupled to the supply valve and the return valve and coupling the supply valve to a supply port of the galley and coupling the return valve to a return port of the galley.

A cooling arrangement for a galley for installation in a transport apparatus includes a cooling energy consumer with a housing with a cooling fluid inlet opening and a cooling fluid outlet opening for the supply and removal of a cooling fluid to and from the housing. A cooling compartment includes an interior for taking up the cooling energy consumer, a cooling air inlet for supplying cooling air to the cooling compartment and a cooling air outlet for removing cooling air from the cooling compartment. The cooling air inlet can conduct the cooling air supplied to the interior over an outer surface of the cooling energy consumer. A conveying device is configured to conduct the cooling air supplied to the interior and conducted over the outer surface of the cooling energy consumer through the housing of the cooling energy consumer via the cooling fluid inlet opening and cooling fluid outlet opening.

A chiller for an aircraft galley beverage cart compartment is disclosed wherein a liquid cooled chiller is located in the cart compartment vertically oriented against a back wall. The chiller engages the carts and circulates chilled air efficiently with a reduced footprint, allowing the depth of the cart compartment to be reduced. The unit includes a proportioning valve to control the amount of fluid through the heat exchanger and a distribution block on the post-cooling side to efficiently route the spent refrigerant.

A system for cooling a thermally insulated galley cart in an aircraft incorporates a skin heat exchanger configured to transfer heat to an aircraft skin. A cooling system is in communication with the skin heat exchanger and is configured to be removably coupled with a thermally insulated galley cart.

A chiller galley cart includes a plurality of walls defining an interior cavity, a supply valve defined in one wall of the plurality of walls, and a return valve defined in one wall of the plurality of walls. The supply valve and the return valve are configured to couple to a chiller positioned in the interior cavity to provide cooled airflow from the chiller galley cart. A method for cooling a demand galley cart positioned in a cart compartment of a galley includes positioning a chiller galley cart in the cart compartment having a chiller positioned in the interior cavity coupled to the supply valve and the return valve and coupling the supply valve to a supply port of the galley and coupling the return valve to a return port of the galley.
