ABSTRACT:
An open loop air cycle air conditioning system draws ambient air into a turbine for expansion and cooling. The air passes through a heat exchanger where it withdraws heat from recirculated cabin air and is passed to a compressor which is operatively coupled to and driven by the turbine to partially recompress the air. The air is directed from the compressor to the intake manifold of the airplane engine. Valves may be positioned at the ambient air inlet to control the flow of air through the air conditioning system and into the engine. Water can be sprayed into the low pressure air at the heat exchanger to provide substantial additional cooling by evaporation.
