The Numerical Analysis of the Thermo-Siphon Self-Injection Refrigeration System

Abstract:

The ejector performances were studied through simulation of solar thermosiphon injection refrigeration system. The influences of operating and structure parameters were analyzed on the eje-ctor performance. Some conclusions had been drawn: the optimum outlet and working pressure were 4241~5622Pa and 57803~70110Pa, the optimum ejector throat area ratio was 6.25, the ejector of 10 mm nozzle separation had maximum entrainment ratio and injecting flow. The influences of shock were analyzed on the ejector. The more shock number of nozzle exit, shock stagnation of the mixed chamber exit and the reflux of conical mixed chamber made the ejector performance decreased.
