1. An air conditioning system for a cabin of an air or rail transport vehicle, comprising:
a pneumatic turbine engine that comprises at least one compressor and at least one turbine and is connected by a mechanical shaft extending along an axis, referred to as the turbine engine axis, said turbine comprising an air inlet and an air outlet, and
a water extraction loop that comprises a heater, a condenser, and a water separator, is arranged fluidically between an air outlet of the compressor and the air inlet of said turbine, and is configured to be able to dry the air supplied to said turbine, wherein:
said heater, said condenser, and said water separator are arranged in series, forming the air inlet of said turbine;
said heater is arranged on the turbine engine axis or around said axis;
said condenser is arranged on the turbine engine axis or around said axis;
said water separator is arranged on the turbine engine axis or around said axis;
said heater is cylindrical and surrounds the axis of the turbine engine and the turbine such that an outlet of a cold pass of the heater leads directly into the air inlet of the turbine, the outlet of the cold pass of the heater abutting the air inlet of the turbine without piping between the outlet of the cold pass of the heater and the inlet of the turbine.
