ABSTRACT:
An air cycle environmental control system regenerates energy through the provision of a reheater condenser that condenses water vapor from compressed air. The condensed water vapor is extracted by a water extractor to produce dehumidified air. A subcooler heat exchanger can receive the dehumidified air for further cooling, but while causing a minimal amount of condensation. A subcooled air from the subcooler heat exchanger is then reheated in the reheater condenser, with a resulting reheated air having absorbed a heat of sensible cooling and heat of condensation. The reheated air then passes into a first turbine which recovers a heat of sensible cooling and heat of condensation. The first turbine expands the air, which then flows through the subcooler heat exchanger and into a second turbine for additional recovery of a heat of sensible cooling and heat of condensation. The second turbine cools the air by expansion for delivery to an enclosure to be conditioned.
