摘　　要：介绍了压缩喷射二级制冷系统的结构,比较了喷射制冷、压缩喷射二级制冷、压缩制冷系统的热性能系数,结果表明压缩喷射二级制冷系统的热性能系数大于喷射制冷系统,在低焓能领域有应用前景。Presents the construction of the system. Compares its thermal performance coefficient with those of ejector refrigeration system and compression refrigeration system. The result shows that the doublestage refrigeration system has larger thermal performance coefficient than that of ejector refrigeration system and can be used in low enthalpy field.
