Abstract

An environmental control system of an aircraft includes a ram air circuit having a ram air shell with at least one heat exchanger positioned therein. A dehumidification system is arranged in fluid communication with the ram air circuit and a plurality of compressing devices are arranged in fluid communication with the ram air circuit and the dehumidification system.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 451,224, filed January 27, 2017, the contents of which are incorporated herein by reference in their entirety. Background technique [0003] Exemplary embodiments relate to the field of environmental control systems, and in particular to an aircraft environmental control system (ECS). [0004] Generally, contemporary air conditioning systems are supplied with a pressure of approximately 30 psig to 35 psig while cruising. The trend in the aerospace industry today is towards more efficient systems. One way to improve the efficiency of an aircraft is to eliminate the blowout entirely and use electricity to compress the outside air. The second method is to use lower engine pressure. The third way is to use the energy in the air going out of the cabin to compress the outside air and bring it into the cabin. Each of these approaches alone offers lim...
