An air cycle environmental control system for an aircraft cabin is disclosed which utilizes cabin exhaust air to power a first stage turbine. This provides a significant increase in compressor power which increases the turbine cooling available in a second stage turbine. The ram air consumption is also reduced due to the cabin exhaust air being ported to the ram air inlet where it merges with the ram air prior to cooling of the bleed air supply in a dual heat exchanger.
An environmental control system for conditioning air prior to passing it to an area, comprising: a. means for cooling air traveling along a first path using air from a first source, the first source air being fed along a second path to the means for cooling; and b. first turbine means for expanding and cooling the first path air, wherein conditioned air exhausted from the area is fed along a third path to the second path where it merges with the first source air and further comprising a second turbine means, disposed in the third path, for expanding and ...
