This paper discusses the conventional and compression enhanced ejector refrigeration cycles using the thermodynamic theory, which demonstrates theorily that the compression enhanced ejector refrigeration cycle can achieve a more high system COP in using low grade heat. The experimental data have been processed and analysed, which show that on the specified conditions:a generator temperature of 90℃, an evaporator temperature of 10℃refrigeration mount of 1KW,the ejector mass flow entrainment can reach 0.45, the system COP can reach 50%.
