摘要

气泡泵液体提升性能直接影响单压吸收式制冷系统制冷性能。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连续提升性能的影响。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.
