摘　　要：介绍了自动复叠制冷系统的工作原理，采用非共沸混合工质R22／R23作制冷工质，经理论计算后确定了混合比，并对自动复叠制冷系统进行了热力计算，搭建了相应的试验装置。经运行调试后，实验台的最低温度达到-53℃，并且箱内温度始终维持在．52℃以下。The working theory of the auto cascade refrigeration system is introduced, non-azeotropic mixture refrigerant R22/R23 is used to be refrigerant, the proportion of the blend refrigerants is determined after theory calculation, and the auto-cascade refrigeration system is thermodynamic calculated, the experimental rig is set up. After the circulate debug, -53℃ low temperatures successfully reached, and -52℃ low temperatures is remain in the equipment.
