摘要： An environmental control system of a vehicle includes a first compression device including a compressor, a first turbine, and a power turbine operably coupled by a shaft. The first turbine is configured to receive a first medium, the compressor is configured to receive a second medium, and the power turbine is configured to receive a third medium. A second compression device, separate from the first compression device, includes a second turbine. The environmental control system is operable in a first mode and a second mode. In the first mode, the second medium is provided to the compressor and the second turbine sequentially. In the second mode, the second medium bypasses the second turbine. In in both the first mode and the second mode, only the second medium is provided to an outlet of the environmental control system.

摘要： An aircraft air conditioning system comprises a process air line configured to supply compressed process air provided by a process air source to an air conditioning unit of the aircraft air conditioning system and a trim air line branching off from the process air line upstream of the air conditioning unit and being configured such that trim air flows through the trim air line, the trim air having been branched off from the compressed process air flowing through the process air line. A compressor is arranged in the trim air line and is configured to compress the trim air flowing through the trim air line. A turbine of the aircraft air conditioning system is configured to drive the compressor. A cabin exhaust air line is configured to supply cabin exhaust air discharged from an aircraft cabin to the turbine for driving the turbine.

摘要： An environmental air conditioning system is described for conditioning compressed air for supply as conditioned air. The system includes an airflow path to which the compressed air for ultimate distribution as conditioned air (i.e., airflow path compressed air) is supplied. Then airflow path has various components of an air cycle system, and also includes a power turbine outside of the air cycle that receives compressed air and discharges it as exhaust. The power turbine transfers power to a compressor in the air cycle system.

摘要： An aircraft air conditioning system includes an air conditioning unit for the production of air conditioning air, which unit is connected to a pack air line, a recirculation air line adapted to be flown through with recirculation air and a mixing chamber, which is connected to the pack air line and the recirculation air line. An inlet line is connected to a connection on the aircraft for an aircraft-external air production unit and opens into the pack air line connecting the air conditioning unit to the mixing chamber. An air conditioning air line branches off from the pack air line between an opening point of the inlet line into the pack air line and the mixing chamber and is connectable to an aircraft area to be cooled.
