Abstract
A system and method for providing conditioned air to an aircraft cabin. The system combines the benefits of a traditional 4 wheel condensing cycle and dual expansion energy recovery cycles. The energy of a heat load such as aircraft electronic or avionics can be recovered and used in a second turbine while a continuous source of cooling for the heat load is provided for high altitude operation when the first turbine is by-passed. The disclosed invention conditions inlet air using an efficient process that recaptures energy that would otherwise be wasted. Recaptured energy can come from aircraft avionics and from moisture in inlet and cabin air.
