摘要：The supersonic ejector-diffuser systems are usually used for cooling by utilizing low-grade thermal energy, but few can be used in subzero refrigeration applications. In this paper, a methodology was proposed and applied to design a two-stage ejector for subzero refrigeration. The two-stage ejector, using R134a as the working fluid, was operated at 63–74 C generator temperature and 24℃ to 0℃ evaporator temperature.
