Abstract

An aircraft air conditioning system comprises a process air source and an air conditioning unit being connected to the process air source via a process air line and being adapted to cool and expand process air supplied to the air conditioning unit from the process air source so as to provide conditioned air. A mixing chamber of the aircraft air conditioning system is connected to the air conditioning unit via a conditioned air line and is adapted to mix conditioned air supplied to the mixing chamber from the air conditioning unit with recirculation air recirculated from an aircraft region to be air conditioned to the mixing chamber via a recirculation air line so as to provide mixed air.
