摘要
针对汽液分离效果差的问题,重新设计了应用于两相流引射器制冷系统的汽液分离器,将使用新汽液分离器的两相流引射器制冷系统的性能与原系统进行了比较,分析了汽液分离器对引射器性能及制冷系统性能的影响。实验结果表明:重新设计的汽液分离器分离效果大大改善,对于不同的实验工况条件,采用新设计的汽液分离器的两相流引射制冷系统,主蒸发器制冷量由占总制冷量的21.1%~27.8%,提升到82.2%~87.3%,主蒸发器起到了主要作用;在引射器结构参数相同的条件下,引射器的引射比由0.2~0.46提升到0.56~0.64;采用新设计的汽液分离器系统制冷量和COP均与原系统基本相同。
The gas - liquid separator was redesigned to resolve the problem of low separation efficiency. The performance of the two -phase ejector refrigeration （TPER） system with redesigned gas -liquid separators was compared to that of the original system. The influence of the gas - liquid separator on the performance of the ejector and the TPER system was analyzed. The experimental results show that the separation effect of the gas - liquid separator is improved greatly. The cooling capacity of the main evaporator of the TPER system with the redesigned gas - liquid separator increases from 21.1% - 27.8% to 82.2% ~ 87. 3% for different working conditions, which means that the main evaporator plays a major role. The entrainment ratio of the ejector increases from 0.2 - 0.46 to 0.56 - 0.64 for the same ejector structure condition. The cooling capacity and COP of the TPER system with the redesigned gas -liquid separator are basically the same as the original system.
