Abstract
A refrigerator-oven combination for an aircraft galley food service system includes a housing with a thermally insulated compartment, a heating device for heating the compartment in a heating mode, and a refrigeration device for cooling the compartment in a refrigeration mode. The heating device includes an electric heater and a steam injection valve disposed within the compartment for heating at least a portion of an interior of the compartment. A temperature sensor disposed within the compartment measures a temperature in the compartment during the heating mode. The refrigeration device may be a chiller that supplies chilled fluid to the compartment, or a separate refrigeration unit which is mounted to the compartment. A control unit connected to the steam injection valve, electric heater, temperature sensor, and refrigeration device is configured to monitor and control the temperature within the compartment during the heating and refrigeration modes.
