Aircraft air conditioning system and method of operating an aircraft air conditioning system

摘要

An aircraft air conditioning system (10) comprises a process air line (12). A ram air channel (32) allowing a flow of ambient air therethrough. A heat exchanger unit (26) is disposed within the ram air channel (32) so as to thermally couple the process air to the ambient air flowing through the ram air channel (32). A water extractor (48) is disposed in the process air line (12) downstream of the heat exchanger unit (26) so as to extract water from the process air. A water supply system (58) supplies water extracted from the process air by means of the water extractor (48) into the ram air channel (32). A control arrangement (64) controls a fluid connection between the water extractor (48) and the ram air channel (32) in dependence on an operating state of the aircraft air conditioning system (10).
