摘　　要：自动复叠制冷循环有其特殊的优点,但是混合制冷剂的配比选取仍需进一步研究。通过搭建一个三级自动复叠制冷循环实验台,并采用常规复叠制冷循环的方法,粗定制冷剂配比,再使用CSD方程微调,实验数据证明该方法的结果比较合理。The auto cascade refrigeration has many special advantages, but the rate of refrigerants is still unsolved. This paper discussed to solve the problem. And through a three - stage auto cascade refrigeration experiment , the result of the experiment proved that this method is usable. So the COP of the refrigeration and the temperature of suction and discharging gas were shown.
