Abstract
Systems and methods for cooling an aircraft galley cart compartment by providing cooling from a potable water flow circuit directed from an aircraft potable water supply to provide direct and indirect cooling are disclosed.
Claims22
A system for cooling an aircraft galley cart compartment, the system comprising:
- a cool potable water flow, said cool potable water flow configured to initiate from an aircraft potable water supply;
- a potable water circuit in communication with the aircraft potable water supply;
- an aircraft galley cart compartment configured to be cooled by a potable water flow circulated through the potable water circuit by at least one of direct cooling and indirect cooling;
- and
- wherein, in operation, the potable water circuit is a closed potable water circuit, said closed potable water circuit further comprising a valve, said valve positioned between the aircraft potable water supply and the potable water circuit, and wherein said valve is configured to move from an open position to a closed position to maintain a closed initial potable water charge within the closed potable water circuit.

A method for cooling an aircraft galley cart, the method comprising:
- directing a potable water flow of potable water from an aircraft potable water supply within a potable water circuit in an aircraft, said potable water circuit comprising the potable water flow of potable water at a potable water temperature that is below an aircraft cabin ambient temperature;
- positioning the potable water circuit in communication with at least one of a chilled air circuit and an aircraft galley cart compartment to cool the aircraft galley cart compartment at least one of directly and indirectly;
- maintaining the aircraft galley cart compartment temperature at a temperature ranging from about 32° F. to about 45° F.;
- wherein, in operation, the potable water circuit comprises a closed potable water circuit;
- and
- wherein the closed potable water circuit further comprises a heat exchanger in communication with the closed potable water circuit, said closed potable water circuit directly contacting the aircraft galley cart compartment.

- maintaining the aircraft galley cart compartment temperature at a temperature ranging from about 32° F. to about 45° F.;
- wherein, in operation, the potable water circuit comprises an open potable water circuit configured to remain in open communication with the aircraft potable water supply;
- and
- wherein the open potable water circuit further comprises a heat exchanger in communication with the open potable water circuit, said open potable water circuit directly contacting the aircraft galley cart compartment.
