8 . An aircraft comprising the system of claim 1 .
9 . 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.
10 . The method of claim 9 wherein the closed potable water circuit further comprises a potable water cooling component, said closed potable water circuit directly contacting the aircraft galley cart compartment.
11 . The method of claim 9 , wherein the potable water flow of potable water in the potable water circuit maintains an average temperature ranging from about 35° F. to about 77° F.
12 . The method of claim 9 , further comprising:
directing chilled air from the chilled air circuit to the aircraft galley cart compartment.
13 . The method of claim 9 , further comprising:
directing chilled air from the chilled air circuit to the aircraft galley cart compartment; and
directing a cool potable water flow from the potable water circuit to the aircraft galley cart compartment.
14 . The method of claim 9 , further comprising:
directing a potable water flow from the potable water circuit to the aircraft galley cart compartment; and
wherein the potable water flow from the potable water circuit is exclusively responsible for cooling the aircraft galley cart compartment.
15 . An aircraft galley cart compartment cooled according to the method of claim 9 .
16 . 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 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.
17 . The method of claim 16 , wherein the open potable water circuit further comprises a water cooling system, said open potable water circuit directly contacting the aircraft galley cart compartment.
18 . The method of claim 16 , wherein the open potable water circuit further comprises a heat exchanger in communication with the open potable water circuit.
19 . The method of claim 16 , further comprising:
directing chilled air from the chilled air circuit to the aircraft galley cart compartment.
20 . The method of claim 16 , further comprising:
directing chilled air from the chilled air circuit to the aircraft galley cart compartment; and
directing a cool potable water flow from the potable water circuit to the aircraft galley cart compartment.
