| 为了能够更加准确的掌握影响气泡泵运行性能的参数，提升Einstein制冷循环的性能，在大气压下以饱和水为工质，建立了气泡泵工作的理论模型，开展了相同沉浸比下不同的提升高度对气泡泵提升性能影响的实验。根据理论分析和实验结果，发现在保持其他影响因素不变情况下，理论值与实验值基本趋势一致，液体提升量与竖直提升高度成反比，提升量相差最大可达0.82 g/s；提升效率与提升高度成正比，提升效率最大减少量达10.16 %，对整个制冷系统的性能有重要影响。 |

| Abstract: |
| In order to grasp the influence parameters of bubble pump performance more accurately and improve the performance of Einstein refrigeration, the theoretical model and experiment on bubble pump were carried out with water as the working fluid at atmospheric pressure by using different lift height under the same immersion ratio. According to the theoretical and experimental results, it is found that under the condition of the other factors unchanged, the theoretical and experimental results have the same trend; the amount of the lifted liquid is inversely proportional to the lift height, the lifting capacity difference can reach to 0.82g/s; the lift height is proportional to the lifting efficiency, and the maximum lifting efficiency difference can reach to 10.16%, which has a important effect on the whole refrigeration system. |
