摘　　要：卫星部组件热真空试验设备制冷系统提供试验设备的冷黑环境。文章介绍了复叠制冷系统的工艺流程和系统组成,说明了制冷系统的性能特点。为了满足试验设备的长寿命性能,对复叠制冷系统进行了可靠性设计。复叠制冷系统可以应用于卫星部组件热真空试验设备、高低温试验箱以及医用低温箱等。Low temperature environment is simulated by using a cascade refrigeration system in the thermal vacuum test facility of spacecraft subassembly. The flowchart and the characteristics of the cascade refrigeration system are given in this paper. Design for a cascade refrigeration system is optimized with respect to the life and reliability of the test facility. The cascade refrigeration system can be applied to the thermal vacuum test facility of spacecraft subassembly, ordinary pressure high and low temperature test container, low temperature box for medicine, and so on.
