A method, apparatus, system, and computer program product for managing pumps in an aircraft. Flight information about an operation of the pumps in a pump package in the aircraft is received by a computer system. The flight information is received from the aircraft. A number of times that an abnormal switching occurred for the pumps within a window of consecutive flights is determined by the computer system when the abnormal switching is identified from the flight information. A set of actions is performed by the compute system when the abnormal switching occurred a number of times for the pumps within the window of consecutive flights that exceeds a set of thresholds for the abnormal switching that is considered healthy for the pumps.

A divided aircraft galley refrigeration system is disclosed. In embodiments, the system includes an evaporating unit positioned within an aircraft galley. In another embodiment, the system includes a refrigeration and heat discharge unit positioned outside of the aircraft galley. In another embodiment, the system includes a liquid refrigerant pipe configured to fluidically couple the evaporating unit and the refrigeration and heat discharge unit. In another embodiment, the system includes a vapor refrigerant pipe configured to fluidically couple the evaporating unit and the refrigeration and heat discharge unit.

A system may include an aircraft galley, which may include a standard unit meal box compartment configured to hold a standard unit meal box. The standard unit meal box compartment may include a door at a front of the standard unit meal box compartment and an air chiller near a rear of the standard unit meal box compartment. The air chiller may be configured to provide chilled air within the standard unit meal box compartment.

A galley refrigeration system is provided in which a galley cart is positioned in the cavity of a galley compartment comprising at least a cart-facing opening positioned in a vertically intermediate region of the back wall, the galley cart or the galley compartment having a duct-facing opening positioned adjacent to the cart-facing opening. A heat exchanger configured to generate cooling air is provided within the galley compartment, adjacent the vertically intermediate region of the back wall of the galley compartment defining the cavity. An air supply duct, provided at the cart-facing opening, is configured to guide the cooling air from the heat exchanger into the galley cart, and configured to be detachably coupled to the duct-facing opening of the cart or the galley compartment. An electronically actuated valve controls a variable flow rate of the cooling air from the air supply duct into the galley cart.

The present invention concerns a cooling device and method of forming and regenerating same for use in keeping perishable products cool. The cooling device includes a porous substrate that has been soaked in a first composition including at least one anti-freeze agent before being soaked in a second composition including at least one crosslinking agent and be exposed to UV irradiation. The cooling device further includes a substrate cover for sealingly covering the porous substrate after being soaked in the second composition and exposed to the UV irradiation. Prior to use, the cooling device is cooled to a desired temperature and exposed to further UV irradiation.

A sink unit arrangement for a galley provided for installation in a transport vehicle comprises a worktop and a drip tray, which is arranged in an installation opening provided in the worktop and comprises a first section and a second section. The second section has a depth which is greater than a depth of the first section and protrudes through the installation opening provided in the worktop into a free space adjacent to the installation opening.

An environmental control system (ECS) for an aircraft includes at least one cooling turbine, and a turbine bypass valve disposed fluidly upstream of the at least one cooling turbine. The turbine bypass valve is configured to direct a first portion of an ECS output airflow to a first air load at a first pressure via a first outlet passage, and direct a second portion of the ECS output airflow across a cooling turbine of the at least one cooling turbine and to a second air load at a second pressure lower than the first pressure for cooling thereof.

An aircraft galley chiller is adapted to fit within a service column of the aircraft. The condenser is elongated, oriented vertically, and includes a bank of fans to increase airflow. The evaporator is also elongated and includes a bank of fans. The evaporator and condenser are oriented with the same plane to produce a footprint that fits within the service column. The evaporator includes a heater element to periodically heat and de-ice the evaporator.

A vehicle is provided including a structure including a skin defining an outside surface exposed to ambient cooling flow and an inside surface. The structure includes a first structural member extending from the inside surface of the skin and a second structural member extending from the inside surface of the skin; and a thermal management system including a heat exchanger assembly positioned adjacent to, and in thermal communication with, the inside surface of the skin, the heat exchanger assembly positioned at least partially between the first and second structural members of the structure.

In a preferred embodiment, a modular galley monument for an aircraft cabin includes a first side panel, a second side panel, and an upper surface connecting the first side panel and the second side panel. The modular galley monument may include dividers partitioning the monument into a number of compartments. The monument may include an upper monument portion and a lower monument portion connected at a periphery via a seal allowing for vertical deflection between the first monument portion and the second monument portion of at least one inch while maintaining contact with both. The monument may include an integrated heating appliance for a compartment, including an insulation shell, a heated compartment positioned within the insulation shell, an electrical heating unit disposed within the insulation shell and configured to provide heat energy to the heated compartment. And a door assembly rotatably connected about an opening of the heated compartment.
