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 cart bay for an aircraft galley structure includes a housing defined by interior surfaces and capable of housing one or more removable galley carts in a secured position. Chilled air is introduced into the cart bay through a plenum of inlet to maintain perishable contents of the galley cart at a safe temperature. The side walls of the cart bay include rubstrip assemblies for guiding the galley carts in and out of the bay, absorbing impact and noise. The rubstrip assemblies may include a corrugated carrier layer behind a solid rubstrip; the corrugated carrier layer includes apertures for controlling and directing the flow of chilled air along the side walls to maximize the exterior surfaces of the galley carts reachable by the chilled air, separating the galley carts from the side walls and allowing chilled air to reach the side exterior surfaces of the galley carts via the apertures.

A galley cart includes walls defining an interior cavity extending between a front and a rear of the galley cart and the interior cavity extending between a top end and a bottom end. A supply port is provided in flow communication with the interior cavity at or near either the top end or the bottom end of the cart. A return port is provided in flow communication with the interior cavity that is adjacent the supply port at or near the top end or the bottom end of the cart. A barrier is positioned between the supply port and the return port within the interior cavity of the cart to define a supply chamber and a return chamber to control airflow through the interior cavity.

A galley cooling system for installation in a transportation means, in particular an aircraft, comprises a cooling device comprising a coolant circuit configured to be flowed through with a coolant. The cooling system further comprises a first fluid line configured to be flowed through with a first fluid and being thermally coupled with the coolant circuit to transfer heat from the first fluid line fluid to the coolant circuit coolant, and a second fluid line configured to be flowed through with a second fluid and being thermally coupled to the coolant circuit to transfer heat from the coolant circuit coolant to the second fluid line fluid. The second fluid line comprises a first portion integrated into or arranged adjacent to a galley worktop, the first portion of the second fluid line being configured to be flowed through with the second fluid in a direction parallel to the worktop.

An air supply and return system for a heat exchanger of a galley includes a supply duct configured to extend from the heat exchanger to a cart compartment of the galley, an air-through supply vent in flow communication with the supply duct and configured to be in flow communication with an air-through galley cart in the cart compartment, an air-over supply vent in flow communication with the supply duct and configured to be in flow communication with the cart compartment for supplying cooled airflow for an air-over galley cart in the cart compartment, and a return duct configured to extend from the cart compartment to the heat exchanger to return air to the heat exchanger. The return duct has an air return device in flow communication with the return duct and configured to be in flow communication with the cart compartment to receive airflow therefrom.

An apparatus for pre-heating potable water in aircraft with waste heat includes an air to water heat exchanger having a heat exchanger housing with an inlet end that receives heat from one or more of a galley insert exhaust air inlet, a galley appliance exhaust air inlet and an air chiller exhaust air inlet. A potable water supply inlet supplies potable water to the air to water heat exchanger, which transfers heat to the potable water, and a potable water supply outlet supplies heated potable water, such as to a galley insert or galley appliance, for example. An exhaust air outlet vents cooled exhaust air from the air to water heat exchanger.

A cooled cup holder provides for a cooled beverage container that is connectable to a vehicle's air conditioning system to maintain a drink cold. The assembly can additionally be provided with a second compartment which can keep a snack or sandwich cool. The cup holder assembly can be adapted to be suspended from the map pocket panel, or can be provided with its own map pocket, in which case, the assembly will replace the airplane's map pocket.

A method and apparatus for drying objects in low-volume enclosed spaces is disclosed. In one embodiment, the apparatus is a hand dryer that comprises a dryer cavity including an input port, an exhaust port, and an opening for insertion of a hand having moisture thereon, an air channel, pneumatically coupling the exhaust port of the dryer cavity to the input port of the dryer cavity, the air channel substantially isolated from an interior volume of the lavatory, and a blower, communicatively coupled to the air channel, for moving air through the air channel and the dryer cavity.

A modular chiller for an aircraft galley trolley compartment disposed below a galley work deck. The modular chiller includes an enclosure for components configured to chill air circulating throughout the trolley compartment. The modular chiller includes a heat exchanger for chilling air entering the enclosure from the trolley compartment through air return ports. The modular chiller includes a fan for directing air flow through the enclosure, wherein a speed of the fan is controllable by a controller thereby causing adjustment in a volume of the air passing through the heat exchanger. The modular chiller includes connection ports configured to couple the modular chiller to one or more aircraft systems, the connection ports including quick disconnect connections for aircraft line replacement units, wherein the plurality of connection ports comprise at least one connection port for supplying liquid refrigerant to the modular chiller.
