Abstract：
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 double-stage refrigeration system has larger thermal performance coefficient than that of ejector refrigeration system and can be used in low enthalpy field.
