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 system for preparation and delivery of meals includes a kitchen appliance for cooking or storing food and a food service cart with a frame for carrying meals and a temperature sensor for insertion into the meal. The kitchen appliance and the cart communicate wirelessly with each other. The cart is insertable into the kitchen appliance and includes the temperature sensor, which transmits information to a first communication box, which communicates wirelessly with peripheral devices and transmits the current temperature of the meal, and a second communication box communicates wirelessly with a controller for controlling the kitchen appliance. The second communication box connects to an external power source, and the cart includes an energy storage means. The first communication box allows wireless charging of the energy storage means. A method for preparation and delivery of meals with the use of such a system is also disclosed.

A system for cooling an aircraft galley trolley. The system includes a trolley cooling compartment for stowing an aircraft galley trolley; and a heat exchanger to provide cold air to the trolley cooling compartment. The trolley cooling compartment defines an inlet proximal to the base of the trolley cooling compartment for receiving the cold air. The trolley cooling compartment cools the aircraft galley trolley through the transfer of heat to the cold air. The transfer of heat to the cold air heats the cold air to produce warmer air.
