<p>The method of ventilating an aircraft cabin (11) involves compressing air in the gas turbine compressor stage (4) and cooling the air by heat exchange (3) with exterior air. The compressor stage turbine (5) is fed with the cooled air and the fresh air (10) is then fed to the cabin. Air leaving the cabin is fed into the compressor to release collected energy to a second turbine stage (15) connected to the first. Further heat exchangers (14,16) can be placed on either side of the second turbine stage to further transfer of cooling energy to the heat exchanger (3) outlet. An Independent claim is included for a circuit for carrying out the method.</p> |
