Summary

The paper describes the investigations of the R718 thermocompression refrigerating cycle with two-phase ejector as a compression device. The complex thermal and flow phenomena connected with compression and condensation inside the two-phase ejector flow field are investigated and performance characteristics are estimated. The thermodynamic processes are shown in pressure (enthalpy and temperature) entropy diagrams. Based on the described thermodynamic model, a computational procedure was generated to evaluate the performance characteristics of this R718 refrigerating system. The implementation of the proposed R718 two-phase ejector refrigerating/heat pump systems for utilization of low temperature heat and waste heat is discussed.
