Essay

The thesis is dedicated to efficiency improvement of ejectors and heat-driven ejector refrigeration machines operated with low-boiling working fluids. The results of a theoretical investigation of the performance characteristics of an ejector and ejector cooling machine at design and off-design conditions are pro-vides.An ejector test rig is developed and experimental results at various operating conditions are presented and evaluated. It is proven that for ejector with fixed flow part geometry maximum of efficiency could be reached not only for design condi-tions but also for some of off-design conditions.
