Binary fluid ejector and method of use

Abstract

A binary-fluid oscillating-jet pressure exchange ejector and binary-fluid ejector refrigeration cycle as a method of use are disclosed. The ejector includes a high aspect ratio jet nozzle geometry, spatial domain jet modulation, serpentine jet stream morphology and distinct fluid pathway geometry capable of equilibrating or otherwise processing dissimilar fluids. As a method of use, the binary fluid ejector provides a means to substantially optimize the binary fluid set selected or otherwise formulated for employment in a binary-fluid ejector refrigeration cycle exclusively to favor refrigeration thermal performance (COP), without compromising the performance of the ejector itself.
