摘　　要：对新型的压缩/喷射式制冷系统进行了介绍,对这一系统的重要部件喷射器进了设计计算并编写了喷射器的结构计算程序。然后对新型制冷系统的变工况特性进行了研究分析,结果表明此新型的制冷系统较传统蒸气压缩式制冷系统能够有效地提高系统的性能。A new compression/jet refrigeration system is introduced, and the physical dimension of the injector which plays an important part in the system is calculated and then a program is made up. Then the characteristics under variable working conditions of the new system are analyzed, the results show that the performance can be effectively improved of the new type refrigeration system ,compared with the traditional vapor compression refrigeration system.
