Abstract
An air conditioning system for an aircraft includes a first rotatable shaft with a first compressor, a first turbine, a cooling air fan, and an auxiliary compressor connected for rotation therewith, and preferably further includes a second rotatable shaft with a second compressor and a second turbine connected for rotation therewith. A compression, cooling, and expansion cycle driven by at least the first compressor and the first turbine provides a principle flow of air conditioning air. The auxiliary compressor draws in outside air and provides a redundant auxiliary ventilation air flow, which is supplied into the installation space in which the air conditioning unit is installed, or another space in the aircraft that requires a reliable constant ventilation and cooling whenever the air conditioning unit is operational. The auxiliary ventilation air may be connected to a common air distribution network with other air conditioning units.
