<p>An air cycle environmental control system regenerates energy through the provision of a reheater condenser (19) that condenses water vapor from compressed air. The condenser water vapor is extracted by a water extractor (21) to produce dehumidified air. A subcooler heat exchanger (23) can receive the dehumidified air for further cooling, but while causing a minimal amount of condensation. A subcooled air (24) from the subcooler heat exchanger (23) is then reheated in the reheater condenser (19), with a resulting reheated air (25) having absorbed a heat of sensible cooling and heat of condensation. The reheated air (25) then passes into a turbine (26) where the heat of sensible cooling and heat of condensation are recovered. The turbine (26) expands the air, which then flows through the subcooler heat exchanger (23) and finally to an enclosure to be conditioned.</p> |
