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.

Claims

1. A refrigerator-oven combination for an aircraft galley food service system, said refrigerator-oven combination having a heating mode for heating food items, and a refrigerator mode for cooling food and beverage items, the refrigerator-oven combination comprising:

a housing defining a thermally insulated compartment;

a steam heating device disposed in said thermally insulated compartment for heating at least a portion of an interior of said thermally insulated compartment;

a refrigeration device disposed in said housing for cooling at least a portion of the interior of said thermally insulated compartment; and

a motorized fan disposed in said thermally insulated compartment for circulating air within said thermally insulated compartment.

2. The refrigerator-oven combination of claim 1, wherein the steam heating device comprises a steam injection valve for injecting heated moisture into said thermally insulated compartment.

3. The refrigerator-oven combination of claim 1, wherein the refrigeration device comprises an active refrigeration device.

4. The refrigerator-oven combination of claim 1, wherein the refrigeration device comprises a passive refrigeration device.

5. The refrigerator-oven combination of claim 1, wherein the refrigeration device comprises a chiller for supplying chilled fluid to a heat exchanger mounted to said thermally insulated compartment.

6. The refrigerator-oven combination of claim 5, wherein the refrigeration device further comprises at least one temperature sensor located within said thermally insulated compartment and a regulating valve connected to the chiller for metering the flow of the chilled fluid through the heat exchanger for controlling the temperature of said thermally insulated compartment responsive to said at least one temperature sensor.

7. The refrigerator-oven combination of claim 1, further comprising a temperature sensor disposed in said thermally insulated compartment for measuring a temperature in the refrigerator-oven combination during the heating mode.
