传统的喷射式制冷系统COP值较低、经济性较差。提出了一种新型喷射式无泵循环制冷系统———在传统喷射式制冷系统之上增加一个气气喷射器。介绍了该制冷系统的工作流程，并对其进行建模，并分析了系统的工作性能。结果表明：当压缩比大于8时，该系统较传统喷射式制冷系统的COP提高20％以上。

The traditional ejector refrigeration system is low in COP value and poor in economy. Presents a novel ejector refrigeration system of pumpless cycle.Compared to the traditional system,the novel ejector refrigeration system applies a gas-to-gas ejector.Presents the working flow of the novel system,develops the simulation model,and analyses the working performance of the novel system.The results show that the COP value is improved by more than 20% for the novel system compared to the traditional system on condition of compression ratio higher than 8 .
