<p>An air cycle environmental control system for an aircraft cabin is disclosed which utilizes cabin exhaust air (200) to power a first stage turbine (108). This provides a significant increase in compressor power which increases the turbine cooling available in a stage turbine (112). 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 (132).</p> |
