Galley cooling system and method of operating a galley cooling system

A method of operating a galley cooling system suitable for use in an aircraft, comprising the steps:

• supplying a cooling fluid provided by a cooling unit to a trolley compartment configured to receive a predetermined maximum number of trolleys comprising a front side access opening, a back wall arranged opposite to the front side access opening and two sidewalls via a cooling fluid inlet provided in the first side wall of the trolley compartment, and
• discharging cooling fluid heated upon circulating through the trolley compartment from the trolley compartment via a cooling fluid outlet provided in the first side wall of the trolley compartment,
• controlling at least one of a volume flow, a speed and a direction of flow of the cooling fluid supplied to the trolley compartment from the cooling unit in such a manner that the cooling fluid entering the trolley compartment via the cooling fluid inlet is guided first across an outer surface of a bottom wall of a trolley received within the trolley compartment in the case the predetermined maximum number of trolleys is received within the trolley compartment, thereafter the cooling fluid is guided across an outer surface of a side wall of the trolley which faces away from the first side wall of the trolley compartment, and finally is guided across an outer surface of a top wall of the trolley,
• guiding a flow of cooling fluid through at least one recess provided in the region of a mounting surface of at least one guiding element mounted to an inner surface of a second side wall of the trolley compartment, wherein the mounting surface of the guiding element faces the sidewall of the trolley compartment, and wherein the guiding element further comprises a guiding surface configured to interact with the sidewall of a trolley when the trolley is pushed into the trolley compartment,
• wherein the guiding element, in the region of the mounting surface facing the sidewall of the trolley compartment is provided with at least one recess allowing a flow of cooling fluid therethrough.

A galley cooling system, the galley cooling system comprising:

• a cooling unit configured to provide a cooling fluid, and
• a trolley compartment configured to receive a predetermined maximum number of trolleys comprising a front side access opening, a back wall arranged opposite to the front side access opening and two sidewalls,
• wherein a cooling fluid inlet is provided in the first side wall 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, and
• wherein a cooling fluid outlet is provided in the first side wall 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, and
• wherein the galley cooling system further comprises a control unit which is adapted to control at least one of a volume flow, a speed and a direction of flow of the cooling fluid supplied to the trolley compartment from the cooling unit in such a manner that the cooling fluid entering the trolley compartment via the cooling fluid inlet is guided across an outer surface of a trolley received within the trolley compartment in the case the predetermined maximum number of trolleys is received within the trolley compartment,
• the control unit being configured to control the direction of flow of the cooling fluid supplied to the trolley compartment from the cooling unit in such a manner that the cooling fluid entering the trolley compartment via the cooling fluid inlet is guided first across an outer surface of a top wall of a trolley received within the trolley compartment, thereafter is guided across an outer surface of a side wall of the trolley which faces away from the first side wall of the trolley compartment, and finally is guided across an outer surface of a bottom wall of the trolley,
• wherein a guiding element extends into an interior space of the trolley compartment from a second side wall of the trolley compartment,
• wherein the guiding element, in the region of a mounting surface facing the sidewall of the trolley compartment is provided with at least one recess allowing a flow of cooling fluid therethrough.
