With the development of society, severe energy situation, as well as higher and higher environmental protection requirements, how to improve energy efficiency and achieve sustainable development of society has become the research goal of more and more scholars. The cascade utilization based on energy grade and multi-energy complementary distributed energy system are the important development direction of energy technology in the future. One of them is the combined cooling and electricity cycle, which combines the organic Rankine cycle with the ejector refrigeration cycle. The ejector is the key component in the combined cycle of cooling and electricity. The ejector was modeled by the most commonly used one-dimensional isobaric mixing model. The thermal efficiency and exergy efficiency of the cycle were analyzed. The effects of condensation temperature, evaporation temperature, outlet temperature of steam generator and exhaust pressure on the cycle performance were analyzed. The analysis of the system shows that the greatest loss occurs in steam generator, condenser and ejector.
