中文摘要：
本文提出一种将补气结构设置于滑板上的新型滚动转子压缩机结构,该结构能保证吸气结束后补气口才向压缩腔打开,避免了补气回流至吸气管导致的容积效率降低。通过建立数值模型,对该新型结构进行了模拟研究。结果显示：该新型结构可完全避免喷射过程中喷射制冷剂回流至吸气腔;与传统结构补气单缸滚动转子压缩机相比,带有新型喷射结构的单缸滚动转子压缩机的容积效率提升2.6%～3.7%。
英文摘要：
A novel vapor injection structure on blade for rotary compressor is put forward. In the new mechanism,the inject port will keep close until the gas suction process is finished and the compression pocket is isolated from the suction tube,which avoids the backflowing of the injection refrigerant into the suction tube and the decrease of the volumetric efficiency. Based on a verified numerical model,the performance of the new configuration is investigated. The results indicate that：（ 1） this vapor injection mechanism can well eliminate the back-flowing of the injected refrigerant;（ 2） compared with the traditional injection configuration,the novel structure can enhance the volumetric efficiency 2. 6%- 3. 7%.
