ABSTRACT:
An air cycle refrigeration system which comprises an air-to-air heat exchanger, first and second turbochargers, and first and second ejector pumps. The system air to be cooled is passed through the heat exchanger and into a first turbine, cooling upon expansion and driving the coupled first compressor. The system air passes from the first turbine to the second turbine, again cooling upon expansion and driving the coupled second compressor. Each compressor is connected with the coolant air outlet of the heat exchanger and draws the coolant air therefrom. The high pressure air produced from the outlets of the compressors are used to drive corresponding ejector pumps. The ejector pumps are connected with the coolant air outlet of the heat exchanger and draw additional air therefrom. The total draw of coolant air through the heat exchanger therefore comprises the total of the inlet air to the two compressors and the induced air drawn from the heat exchanger by the two ejector pumps.
