Patent ID: 8061154

Claim:
A cooling system for the cooling of heat producing devices in an aircraft, comprising: a central cold producing device including at least two cooling machines working independently of each other, at least one cold consumer, and a cold conveyance system which connects the cold producing device and the at least one cold consumer, the cold conveyance system including at least two independent cooling circuits each of the at least two independent cooling circuits coupled to the cold producing device so as to supply supplying a cold carrier medium that has been cooled by the cold producing device to the at least one cold consumer and return returning the cold carrier medium from the at least one cold consumer to the cold producing device, whereby the at least two cooling machines are coupled in parallel to the cold conveyance system such that each of the at least two independent cooling circuits are thermally coupled to the at least two cooling machines; and wherein the at least two cooling machines use air outside of the pressure cabin of the aircraft as a heat sink in order to expel heat, and the warm extracted air is expelled outside of the pressure cabin.
