摘　　要： 在自复叠制冷循环中,经过大量的实验测试,发现在实验中存在气液分离器液体温度偏低、蒸发器出现换热系数过小以及蒸发器制冷量过小,但仍能循环等特殊的现象,这些现象在理论基础上无法解释。针对这些现象,进行了详细的描述,分析并结合实验数据给出一些见解与推测,这有助于对自复叠系统更加深入的研究。 Based on a lot of experiments in the auto-cascade refrigerating system,some special phenomena could not be explained easily.Such as the temperature of liquid is lower than that of mixing refrigerants in the gas-liquid separator,the heat transfer coefficient of evaporator is litter than 1/10 that normal.The cooling capacity of evaporator is very small,but mixing refrigerants still circulate in auto-cascade refrigeration cycle.These phenomena and the corresponding experimental data were described and primary analysis were proposed.
