Condensing ejector for second step compression in refrigeration cycles.

Author(s) : BERGANDER M. J., SCHMIDT D. P., HEBERT D. A., et al.

Summary

This paper describes a novel approach to the Rankine vapour compression cycle for cooling and refrigeration. The specific innovation is the application of a two-phase device known as a "condensing ejector" for a second step of compression. The innovation has the potential of increasing the efficiency of the standard single-stage vapour compression cycle through a reduction of mechanical compression at the expense of harnessing kinetic energy of gas in the ejector device. In addition, it will reduce the greenhouse gas emission by providing the same amount of cooling with less electric energy consumption. This is the continuation of the developmental work performed under the funding from the NSF and US Dept. of Energy.
