| 摘 要： | 气泡泵液体提升性能直接影响单压吸收式制冷系统的制冷性能。本文以带均流器的多管导流型气泡泵为研究对象,以水为工质,研究了不同加热功率下提升管沉浸比变化对气泡泵提升性能的影响。结果表明:在气泡泵开机运行较短时间内,随着沉浸比的提高,气泡泵总液体提升量逐渐减小,与加热功率为1 450 W、沉浸比为0.5时相比,当加热功率为1 250 W、沉浸比为0.3时,气泡泵总液体提升量提高3.04 kg;在长时间运行工况下,增加沉浸比能显著提高气泡泵提升性能。对于多管导流式气泡泵,增加均流器能有效优化气泡泵运行状况,提高气泡泵总液体提升量,并增大气泡泵提升效率。

| Abstract: | The performance of a bubble pump directly influences the performance of a single-pressure absorption refrigeration cycle. On the basis of a guided bubble pump with a current equalizer and multiple tubes, this research was focused on analyzing the influence of different immersion ratios on the bubble pump performance under different heating power, which used water as a working fluid. According to the experimental results, when the bubble pump operated for a short time from starting, the total lifting capacity decreased with the increase in the immersion ratio. For example, when the heating power and immersion ratio were 1 250 W and 0.5, respectively, the total lifting capacity was 3.04 kg heavier than that under the heating power and immersion ratio of 1 450 W and 0.5, respectively. However, the bubble pump performance under a long term working condition can be significantly improved by increasing the immersion ratio. In addition, the performance of the guided bubble pump can be effectively optimized by adding a current equalizer. The total lifting capacity and efficiency of the bubble pump can also be increased. |
