Title
(EN) TWIN-TURBINE AIR CONDITIONING SYSTEM
(FR) SYSTÈME DE CONDITIONNEMENT D'AIR BITURBINE
Abstract
(EN)
The invention concerns an aircraft cabin air conditioning system, comprising two motorised turbomachines (16a, 16b) each comprising a compressor (14a, 14b) supplying an outlet (24) common to the compressors and a turbine, one of the turbines, referred to as the water extraction turbine (16a), being dedicated to a water extraction loop (28) and the other turbine, referred to as the cooling turbine (16b), helping cool the air. The air conditioning system comprises a network of pipes and associated valves, connected to the common outlet (24) of the compressors and supplying, from the common outlet of the compressors: either the intake (160) of the water extraction turbine (16a), or the intake (164) of the cooling turbine (16b), bypassing the turbine (16a) and the water extraction loop, or, directly, an outlet (60) of the air conditioning system, bypassing the cooling turbine (16b) and the water extraction turbine (16a).

L'invention concerne un système de conditionnement d'air d'une cabine d'un aéronef, comprenant deux turbomachines (16a, 16b) motorisées comprenant chacune un compresseur (14a, 14b) alimentant une sortie (24) commune aux compresseurs et une turbine, une des turbines dite turbine (16a) d'extraction d'eau étant dédiée à une boucle (28) d'extraction d'eau et l'autre turbine dite turbine (16b) de refroidissement permettant un refroidissement d'air. Le système de conditionnement d'air comprend un réseau de conduites et de vannes associées, relié à la sortie (24) commune des compresseurs et permettant d'alimenter à partir de la sortie commune des compresseurs : soit l'entrée (160) de la turbine (16a) d'extraction d'eau, soit l'entrée (164) de la turbine (16b) de refroidissement en contournant la turbine (16a) et la boucle d'extraction d'eau, soit directement une sortie (60) du système de conditionnement d'air, en contournant la turbine (16b) de refroidissement et la turbine (16a) d'extraction d'eau.
