Patent ID: 7231778

Claim:
A method for cooling a galley food cart on an aircraft comprising: transferring heat from a galley food cart by a point-of-use heat exchange system to a liquid cooled condenser, wherein said step of transferring heat from said galley food cart comprises cycling a flow of cooling air from a heat exchanger cooled by said liquid cooled condenser through an air over system to provide cooling air over at least one food cart in a galley cabinet; circulating liquid coolant through said liquid cooled condenser to remove heat from said liquid cooled condenser; circulating said liquid coolant from said liquid cooled condenser in a liquid coolant loop to a heat expelling heat exchanger expelling heat to a heat sink for cooling said liquid coolant; and circulating cooled liquid coolant in said liquid coolant loop to said liquid cooled condenser, and wherein said liquid coolant is maintained at a temperature from about 15° F. to about 30° F. above a temperature of said heat sink.
