Abstract:
An environmental control system for conditioning water-vapor bearing compressed air for supply as conditioned air, the system comprising:a compressor to further compress said compressed air and to deliver the further compressed air to the system;a condenser downstream of the compressor to receive the further compressed air and to condense at least a portion of the water-vapor in the further compressed air to deliver dehumidified compressed air to the system;a first turbine downstream of the condenser to receive the dehumidified compressed air and to expand the dehumidified compressed air to cool the dehumidified compressed air; anda second turbine downstream of the first turbine to receive the expanded dehumidified compressed air, the second turbine rotatable independent of rotation of the first turbine to further expand the expanded dehumidified compressed air to cool the expanded dehumidified compressed air and to power the compressor.
