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 and a divider arranged within the ram air shell to separate the ram air shell into a first region and a second region. The at least one heat exchanger is arranged within both the first region and the second region. A first medium is configured to flow through the first region and a second, distinct medium is configured to flow through the second region. The environmental control system additionally includes a dehumidification system arranged in fluid communication with the ram air circuit and a compression device arranged in fluid communication with the ram air circuit and the dehumidification system.

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, a dehumidification system arranged in fluid communication with the ram air circuit, and a compressing device arranged in fluid communication with the ram air circuit and the dehumidification system. The compression device includes a compressor and a first turbine coupled to one another via a shaft. During operation of the first turbine, work is extracted from a first medium within the first turbine to power the compressor. At an outlet of the first turbine, a temperature of the first medium is above freezing and at least a portion of the moisture within the first medium is condensed.

Abstract: A system and method that comprises an air cycle machine, a flow of bleed air, at least one heat exchanger, and an inlet configured to supply the flow of the bleed air is provided. The bleed air flows from a source to mix with recirculated air in accordance with a high pressure mode or a recirculation chilling mode. The system and method also can also utilize the recirculated air flowing from the chamber to drive or maintain the air cycle machine in accordance with the above modes.

Abstract: An airplane is provided. The airplane includes an environmental control system that provides a pressurized medium to a chamber of the airplane. The airplane also includes a bleed system. The bleed system includes a plurality of ports, each of which can provide a bleed medium from an engine of the airplane to the environmental control system. The plurality of ports includes at least a first port, a second port, and a third port. The first port is selected for an idle condition. The second port is selected for a hot day cruise condition. The third port is selected for a standard operating condition. The bleed system can operate in a first mode, a second mode, or a third mode to provide the bleed medium to the environmental control system from the first port, the second port, or the third port respectively.

Abstract: A compressing device added to a cabin air conditioning system to increase a pressure of air in the cabin air conditioning system itself and, thus, allow for lower pressure air to be bled from the engine. For instance, the compressing device allows air to be bled from a low, rather than a high, pressure locations of the engine.

IPC: B64D13/06
Abstract: A system, which includes a plurality of heat exchangers and a compressing device, prepares a medium bled from a low-pressure location of an engine and flowing through a plurality of heat exchangers into a chamber. The compressing device is in communication with the plurality of heat exchangers and regulates a pressure of the medium flowing through the plurality of heat exchangers. The compressing device includes a turbine that provides supplemental power to the compressing device based on a pressure of the medium in the chamber.
