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 heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates () and fins () of the heat exchanger, the fluids flowing in a multitude of passage channels () each consisting of a closed space () delimited by two adjacent plates and two adjacent fins,

Heat exchanger having optimized fluid passages

The invention relates to a regulator, configured to receive a hot air flow via an air inlet (), to treat this hot air and to transmit the treated hot air to an air outlet () configured to supply a pneumatic actuator (), comprising at least one temperature-sensitive electrical and/or mechanical element (), and a regulator body (). The regulator is characterized in that the regulator body is composed of a heat-conducting hollow enclosure () at least partially surrounding a duct () for transporting the hot air flow, said cavity being at least partially filled with a metal mesh produced by additive manufacturing that allows the cooling air to circulate, and in that the temperature-sensitive electrical and/or mechanical element () is arranged in, or in contact with, the regulator so as to be cooled by the cooling air by thermal conduction.

Porous regulator with integrated ventilation

A tubular heat exchanger () comprising: a fluid circulation chamber () intended to be supplied with a first fluid, referred to as outer fluid, brought to a first temperature, a heat exchange matrix () housed in said circulation chamber and formed by a plurality of heat exchange tubes () each comprising at least one pair of ducts () nested one inside the other, extending along a direction, referred to as longitudinal direction, and defining: a channel for circulating a fluid, referred to as inner channel (), suitable for being able to be supplied with a second fluid, referred to as inner fluid, brought to a second temperature, and a channel for the circulation of a fluid, referred to as intermediate channel (), and suitable for being able to be supplied with a third fluid, referred to as intermediate fluid, brought to a third temperature, different from said first temperature.
