摘　　要：喷射式制冷系统结构简单、运行可靠,可以利用低品位能源,在倡导节能和可再生能源利用的背景下,格外受到关注。传统的喷射式制冷系统循环需要循环泵,消耗电能,而无泵喷射式制冷系统不仅可以利用低品位能源,还可以应用于一些无电力场合。本文比较几种典型的无泵循环式喷射式制冷系统,分析各自的特点和适用范围。Due to the advantages of simple structure, reliable operation and utilization of low grade energy source, the ejector refrigeration system has aroused people＇s more and more attention. The traditional ejector re frigeration system needs a circulation pump and consumes electric energy. While no pump jet refrigeration systems can not only save energy further, but also be suitable for some occasions without power. In this paper, some typi cal no pump jet refrigeration systems and their characteristics are compared and analyzed.
