    摘要: The vapor membrane dehumidification device and method for air cycle environment control systems uses a semipermeable vapor membrane for water vapor, air separation. The vapor membrane has a high water to air permselectivity. When air containing water vapor is passed over or through the semipermeable fibers of the membrane countercurrently or crosscurrently to a purge air stream the water vapor may permeate through the fibers. Using a purge air stream of lower water vapor partial pressure relative to the feed moist air stream, the water vapor is moved to the purge air stream due to the partial pressure differential of water vapor and then expelled overboard with the purge air stream. The purge air stream can be replaced with any source of air internal or external to the aircraft such as air from the aircraft cabin.

    摘要: An environmental control system provides for two stage compression and expansion of a bleed air within a cooling cycle, while allowing for a separately driven fan to handle ambient air as a heat sink. The system comprises a plurality of compressors capable of compressing a water vapor bearing air to produce a compressed air. A reheater is capable of cooling the compressed air. A condenser is in flow communication with the reheater, with the condenser being capable of condensing the water vapor. A water extractor is in flow communication with and intermediate of the condenser and the reheater. A plurality of turbines are in flow communication with and downstream of the reheater.

    摘要: An aircraft architecture may be designed to create an optimal balance between electric power and bleed power in order to match or improve current more electric architecture (MEA) performance while simplifying power extraction from the engines as well as simplifying the electrical system. Conventional aircraft architectures may use electric only ECS and cabin pressurization systems (so-called “no bleed” systems). Alternatively, older conventional aircraft may use strictly engine bleed air to provide power for ECS and cabin pressurization systems. The present invention, on the other hand, provides an architecture which may optimize the use of both engine bleed air and MEA designs to provide a system that may be simpler and potentially more reliable and available as compared to conventional aircraft architectures.

    摘要: 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.
