Air conditioning system for a cabin of an air or rail transport vehicle using a pneumatic and thermal air source which is separate from the air conditioning source

Abstract

The invention relates to an air conditioning system for a cabin () of an aircraft () comprising: a bleed air source (); a ram-air circulation channel (); a network of pipes and control valves; an air cycle turbine engine comprising at least one compressor () and a power turbine () which are mechanically connected to one another; and at least one primary cooling exchanger (PHX) which is accommodated in said channel (), characterized in that said pipe network comprises a thermal power pipe () which is suitable for being able to fluidically connect, upon control of at least one control valve (), said air outlet () of said power turbine () and said ram-air circulation channel () upstream of said primary exchanger (PHX) so that said bleed air expanded by said power turbine () can form a thermal energy source for said ram air being supplied to said primary circuit of said primary exchanger (PHX).
