摘　　要：自动复叠制冷循环系统结构简单、运行可靠。该循环使用非共沸混合制冷剂,其冷凝分离是否完全直接影响着循环制冷效率的高低。针对这一问题,设计一种新型多级冷凝过滤分离装置,并采用配有该装置的自动复叠制冷循环系统进行实验研究,结果表明该装置不仅实现了非共沸混合工质高、低沸点组元的高效分离,提高了系统的制冷效率和稳定性,而且结构简单、成本较低,具有极强的生产实用性。The structure of automatic cascade refrigeration system is simple, and the operation is reliable. Since the non - azeotropic mixed refrigerants are used, whether the condensing separation is complete or not will directly affect the cooling efficiency. A new type of muhistage condensing filtration disengaging gear is proposed in the paper. A test - bed of automatic cascade refrigeration system equipping with the device is set up for actual application research. The results show that the device can separate high and low boiling point group ef- ficiently. Because of its simple structure and low cost, the device may have important potential of practical application.
