压缩喷射制冷循环射流泵轴向尺寸设计计算

Dimension Analysis along the Axial Direction of the Jet Pump in Compression and Injection Refrigeration Cycle

介绍了射流泵在制冷循环中的工作原理,建立了射流泵的物理模型;分析了自由流束的特性,说明了射流泵中喷嘴距离混合室的最佳尺寸,最佳尺寸能使射流泵的工作性能得到优化。

Introduced the working principle of the jet pump in the refrigeration cycle,and setup the physical model of the jet pump. Got out the appropriate distance between nuzzle and mixing chamber based on analysing the characteristic of the free fluid, and optimized the performance of the jet pump.
