Paper deals with thermodynamic analysis of operation of the two-phase vapour-liquid injector applied as a liquid pump for the ejection refrigeration systems or Organic Rankine Cycle systems for various working fluids. The analysis is based on formulated thermodynamic model on the basis of the developed dimensionless mass, momentum and energy conservation equations. The availability for achieving maximum discharge pressure and compression efficiency were studied on the basis of the formulated model. The analysis covers the following fluids: isobutane R600a, propane R290, R1234yf, R1234ze(E), R717, R152a, R134a, R454A and R513A. The geometry and thermodynamic parameters necessary to achieve discharge pressure higher than motive pressure as well as maximum efficiency were demonstrated for the selected working fluids.
