Patent ID: 6981388

Claim:
An air conditioning system, comprising: at least one heat exchanger, arranged in a ram air duct, for cooling compressed air by a fluid, and comprising at least a first (ACM 1 ) and a second (ACM 2 ) air cycle machine which at the compressed-air end are connected to the heat exchanger, wherein the heat exchanger comprises at least one first heat exchanger unit (PHX 1 , SHX 1 ) and second heat exchanger unit (PHX 2 , SHX 2 ), of which one each is connected at the compressed-air end to one of the air cycle machines (ACM 1 , ACM 2 ) separately from the other heat exchanger such that the first (PHX 1 , SHX 1 ) and second (PHX 2 , SHX 2 ) heat exchanger units are separate from each other at the compressed-air end, and ram air outlet ducts which are fluidically separate from each other are provided, of which one is connected to the first heat exchanger unit (PHX 1 , SHX 1 ) and another is connected to the second heat exchanger unit (PHX 2 , SHX 2 ).
