单压吸收式制冷气泡泵冷态实验及性能分析

The cold experiment and performance analysis on bubble pump in single pressure absorption refrigeration system

单压吸收式制冷是一种可以利用太阳能等低品位能源驱动的制冷循环,而气泡泵是该制冷系统中的最主要耗能部件,因此对气泡泵的研究尤其重要。冷态模拟实验可以避免热态实验中出现的实验过程不稳定等缺点,产生的气泡更加均匀,获得的实验数据更加准确。实验结果表明输气量和沉浸比对气泡泵性能影响较大。

The single pressure absorption refrigeration cycle is driven by solar energy and other low grade energy. It is par tieularly important to research the bubble pump which is the main energy consumption unit of single pressure absorption refrigera tion system. The cold simulation experiment can avoid instability of experimental process appeared in the hot state experiment.The bubble is more even and the experimental data are more accurate. The experimental results show that gas supply volume and immersed proportion both have a great effect on the bubble pump performance.
