1. 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).
