摘要
文中建立了一套单级压缩、四级分凝的自动复叠制冷系统,通过测试,低温槽内5L液体载冷剂能够达到150K。对各级节流后的降温情况进行分析,并指出制冷剂配比不同时所造成的影响。
This paper developed a single - compressed four - stage segregating auto - cascade refrigeration system, the temperature of the liquid coolant in the tank with 5L could reach 150K. Cooling process after throttling were analyzed, the effect of the different proportion of the refrigerants was also pointed out.
