    Abstract: An aircraft is provided. The aircraft includes a pressurized volume and an air conditioning system. The air conditioning system operates in a first mode when the aircraft is performing high altitude operations and a second mode when the aircraft is performing low altitude operations. The first mode includes when a first medium, a second medium, and a third medium are mixed by the air conditioning system to produce a chamber ready medium. The second mode comprises when only the first medium and the second medium are mixed by the air conditioning system to produce the chamber ready medium. The air conditioning system provides the chamber ready medium to the pressurized volume.

    Abstract: An environmental control system of an aircraft includes a ram air circuit including a ram air shell having at least one heat exchanger positioned therein, at least one dehumidification system arranged in fluid communication with the ram air circuit, a compressing device arranged in fluid communication with the ram air circuit and the dehumidification system, and an expansion device separate from the compressing device and arranged in fluid communication with the ram air circuit and the at least one dehumidification system. The environmental control system receives a flow of a first medium and a flow of a second medium. The environmental control system is operable in a plurality of modes and in a first mode, a flow of the first medium is provided to the compressing device and the expansion device in series.

    Abstract: A cooling module of a galley chiller system is provided including an internal chamber. A heat exchanger assembly has air and a liquid coolant flowing there through. The heat exchanger assembly includes a first heat exchanger core and a second heat exchanger core. The first heat exchanger core and the second heat exchanger core are arranged generally sequentially within the internal chamber. Heat transfer within the first heat exchanger core is limited such that a temperature of the air in the first heat exchanger core remains above freezing.

    Abstract: An air separation system includes a high temperature ozone converter, a mechanical separator downstream of the high temperature ozone converter, and an air separator downstream of the mechanical separator. The air separator receives high temperature air and provides high temperature nitrogen-enriched air and high temperature oxygen-enriched air. The air separation system further includes a heat exchanger downstream of air separator that receives and cools the high temperature nitrogen-enriched air.
