ABSTRACT:
In an air cycle environmental control system, a condenser (46) removes water vapor from compressed, ambient, supply air (9) before it is expanded in a first turbine (24). The chilled outlet air (49) from the first turbine (24) is then used as coolant in the condenser (46), absorbing there the heat of vaporization of the condensed water vapor. After passing through the condenser (46), the warmed coolant is then expanded in a second turbine (26). Should the pressure of the supply air fall below predetermined levels, portions of the cycle that degrade performance or become unnecessary are bypassed.
