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.

[ What is claimed is:] [1.] A method for conditioning water vapor bearing air for supply as conditioned air to an enclosure, comprising the steps of:compressing said water vapor bearing air in a plurality of stages to produce a compressed air;cooling said compressed air in a reheater;condensing water vapor from said compressed air in a condenser such that said compressed air can become a dehumidified air;absorbing a heat of sensible cooling and a heat of condensation by said dehumidified air in said reheater; androuting said dehumidified air through at least two turbines for supply to said enclosure.
