Patent ID: 8528348

Claim:
An aircraft cooling system for cooling heat loads on board an aircraft, said aircraft cooling system comprising: a cold producing device, a first cold carrier fluid circuit thermally coupled to the cold producing device and connected to a first heat load in order to carry off heat from the first heat load, a second cold carrier fluid circuit connected to a second heat load in order to carry off heat from the second heat load, a first heat exchanger disposed in the second cold carrier fluid circuit and configured to thermally couple the second cold carrier fluid circuit to an ambient temperature surrounding the aircraft, and a coupling system configured to selectively thermally couple the first cold carrier fluid circuit to the second cold carrier fluid circuit or thermally uncouple the first cold carrier fluid circuit from the second cold carrier fluid circuit, wherein the second cold carrier fluid circuit is not thermally coupled with a cold-vapour process cooling machine if the coupling system thermally uncouples the first and second cold carrier fluid circuits.
