Abstract

An aircraft air conditioning system includes an ambient air line configured to have ambient air flow therethrough and being connected to a mixer of the air conditioning system to feed ambient air to the mixer, and a recirculation air line configured to have recirculation air flow therethrough and being connected to the mixer to feed to the mixer recirculation air discharged from an aircraft area to be air conditioned. A refrigerating machine of the air conditioning system includes a refrigerant circuit configured to have a refrigerant flow therethrough and being thermally coupled to the ambient air line and to the recirculation air line to transmit heat from the ambient air flowing through the ambient air line and from the recirculation air flowing through the recirculation air line to the refrigerant circulating in the refrigerant circuit, before the ambient air and the recirculation air are fed into the mixer.
