Patent ID: 7024874

Claim:
A galley chiller system for an aircraft comprising: at least one condenser having a fluid, said fluid in said at least one condenser rejecting heat to a first surrounding environment; at least one evaporator receiving said fluid from at least one condenser, said fluid in said evaporator absorbing heat from a second surrounding environment including a galley cart and a third surrounding environment including an air duct of an aircraft cooling system, said at least one evaporator including a first evaporator absorbing heat from said second surrounding environment, and a second evaporator absorbing heat from said third surrounding environment; a recirculation evaporator control valve; a controller connected to said control valve controlling a flow of fluid through said control valve into said evaporators to obtain a desired proportion of fluid flow between said evaporators; and a temperature sensor in said third surrounding environment detecting a temperature with said temperature sensor connected to said controller, said controller commanding said control valve in response to said temperature.
