- 摘要：In this paper,a novel NH_3/CO_2 ejector-cascade refrigeration system with regenerator is proposed,which can recycle the waste heat at the outlet of the compressor.After establishing the mathematical model of the system,the theoretical energy and exergy analysis are carried out and compared with the conventional cascade refrigeration system.It is concluded that compared with the conventional cascade refrigeration system,the novel ejector-cascade refrigeration system with regenerator has the advantages of less power consumption of the compressor,less component exergy destruction,high system performance,and is more suitable for working at a lower temperature.Under the working conditions studied in this paper,compared with the conventional cascade refrigeration system,the COP of the novel ejector-cascade refrigeration system with regenerator is increased by9.58%;the exergy efficiency is increased by 9.50%,and the optimal evaporation temperature is about-45℃.
