AIR-CONDITIONING SYSTEM FOR A CABIN OF AN AIR OR RAIL TRANSPORT VEHICLE USING A PNEUMATIC AND THERMAL AIR SOURCE SEPARATE FROM THE AIR-CONDITIONING SOURCE

摘要

The invention relates to an air-conditioning system for a cabin (10) of an aircraft (80) comprising a bleed air source (12); a dynamic air circulation channel (13); a network of ducts and control valves; an air-cycle turbomachine comprising at least one compressor (3) and a power turbine (4) mechanically connected to one another; at least one primary heat exchanger (PHX) housed in said channel (13), characterised in that said network of ducts comprises a thermal power duct (53) suitable for being able to fluidly connect, upon operating at least one control valve (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 bleed air expanded by said power turbine (4) can form a source of thermal energy for said dynamic air feeding said primary circuit of said primary exchanger (PHX).
