摘要

TITLE OF THE INVENTION: Cabin air conditioning system of an air or rail transport vehicle using a pneumatic and thermal air source separate from the air conditioning source The invention relates to an air conditioning system for a cabin (10) of an aircraft (80) comprising a source of bleed air (12); a dynamic air circulation channel (13); a network of pipes and control valves; an air cycle turbomachine comprising at least one compressor (3) and one power turbine (4) mechanically connected to each other,; at least one primary cooling exchanger (PHX) housed in said channel (13), characterized in that said network of pipes comprises a thermal power pipe (53) adapted to be able to fluidly connect, on command of at least one control valve regulation (25, 21), said air outlet (4b) of said power turbine (4) and said dynamic air circulation channel (13) upstream of said primary exchanger (PHX) so that said air bleed expanded by said power turbine (4) can form a source of thermal energy from said dynamic air supplying said primary circuit of said primary exchanger (PHX).
