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 fluidically arranged between an air outlet of the compressor and the air inlet of said turbine (), and is configured to dry the air supplied to said turbine (), characterized in that said heater (), said condenser (), and said water separator () are arranged in series on the turbine engine axis () or around said axis, forming the air inlet of said turbine ().

Air conditioning system with integrated water extraction loop

The invention relates to a loop () for extracting water from an air conditioning system of a cabin () of an air or rail transport vehicle comprising an air cycle turbine engine (), the loop comprising: a condenser (); a three-dimensional mesh grid () housed in an outlet box () of the condenser and configured to be able to capture water droplets in a stream of moist air condensed by the condenser; a water recovery unit () opening on the condenser outlet box () and arranged under the three-dimensional mesh grid () so as to be able to recover, by force of gravity, the water collected by the three-dimensional mesh grid (); an air return pipe () linking the outlet box () to a supply interface for directly or indirectly supplying the turbine of the air conditioning system.
