Abstract: A novel pressure-exchange compressor-expander is disclosed whereby a high energy primary fluid compresses a lower energy secondary fluid through direct fluid-fluid momentum exchange. The pressure-exchange compressor-expander utilizes non-steady flow principles and supersonic flow principles to obtain an ejector-compressor which can attain high adiabatic efficiencies while having a simplicity of construction, small size and weight, and the low manufacturing cost. This disclosure includes a fuel-cell pressurization system and humidity control system utilizing the pressure-exchange compressor-expander. The disclosure includes a novel turbo-charger for internal combustion engines incorporating exhaust gas recirculation capabilities. Further, an air-cycle heat pump suitable for aircraft applications is disclosed utilizing the pressure-exchange compressor-expander.

Abstract: A novel pressure-exchange ejector is disclosed whereby a high energy primary fluid compresses a lower energy secondary fluid through direct fluid-fluid momentum exchange. The pressure-exchange ejector utilizes non-steady flow principles and supersonic flow principles to obtain an ejector-compressor which can attain substantially higher adiabatic efficiencies than conventional ejectors while retaining much of the simplicity of construction and the low manufacturing cost of a conventional ejector. By virtue of the capabilities of the ejector to compress high volumes of secondary fluid, an ejector refrigeration system utilizing water and other environmentally benign refrigerants is disclosed.
