摘要

本文对机械振动强化吸收式制冷传热传质进行实验研究。搭建了一套综合的性能研究实验台，在吸收式制冷机的底部安装了一个电动振动机，使机组在垂直方向上产生振动，分别对振动频率和振幅两个因素对机组性能强化的效果进行实验分析，得出结论：振幅相同时，振动频率对强化效果的影响较大；而在最佳喷淋量下，频率相同时，振幅太大或太小，振动的强化效果都会下降。且在实验范围内，得到最佳强化效果的频率段为20~30 Hz，此时传热的强化效果可达到8%~20%，传质的强化效果可达到10%~25%，制冷量可提高12%~18%。

Abstract

Effects of mechanical vibration on the heat and mass transfer process of absorption refrigerating system had been researched in this paper. A performance appraisal test bench was set up

thus an electrodynamics vibration generator was installed on the bottom of the absorption refrigerating machine to add vertical vibration into the system. Enhancement effects of vibration frequencies and amplitude on the heat and mass transfer process of absorption refrigerating machine were analyzed respectively. The results showed that when amplitude was constant

vibration frequencies had a strong effect on enhancement effect; and under the optimum spray volume and same vibration frequency

the enhancement effect of vibration would be reduced with too high or too low vibration amplitude. And in the range of test

frequency ranges for the best enhancement effect was 20-30 Hz

in these conditions

the enhancement effect of heat transfer could be 8%-20%

the enhancement effect of mass transfer could be 10%-25%

and cooling capacity increased by 12%-18%.
