A review on implementation of the ejector thermo compression in refrigeration systems and heat pumps is presented in this paper. Thermal, flow and performance characteristics of the refrigeration single-phase and two-phase ejectors are analyzed. A calculating procedure for estimation of the main parameters and performance characteristics of the ejectors is presented. The two main sources of thermodynamic irreversibility: the process of momentum transfer in the mixing section and shock waves, or dispersed shock waves, or pseudo-shock waves in the fluid flow field are discussed. The shock waves are feature for gas and dry vapor fluid flow dispersed shock waves are feature for dominantly vapor two-phase fluid flow pseudo-shock waves are feature for dominantly liquid two-phase fluid flow. With appropriate choice of refrigerant and with optimal design of the ejector flow field elements the ejector systems can be successfully applied in various refrigeration / heat pump systems, and in combined (hybrid) and polygeneration thermal systems for utilization of low temperature heat, geothermal energy, solar energy and waste heat.
