| 利用已搭建的装有电动振动系统的溴化锂吸收式制冷实验台，对溴冷机各主要部件的性能进行实验分析。主要分析振动对于吸收式制冷过程中传热和制冷性能的影响。通过实验数据的处理和分析可以看出：在低频振动状态下，蒸发器、吸收器内的换热效果均优于静止的情形，表明低频振动有利于强化换热，同时增加了机组制冷量，提高了机组COP值。 |

| Abstract: |
| Lithium bromide absorption refrigeration testing with an electric vibrating system was established. Making use of the testing, performance of major parts of LiBr absorption chiller is analyzed. The main purpose is to analyze the effect of vibration on the performance of heat transfer and cooling during absorption refrigeration. The results indicate that compared with static conditions, the heat transfer property of the absorber and the evaporator has a better performance under vibrating conditions. The vibration contributes to heat transfer enhancement, increases refrigerating capacity and improves the COP. |
| Key words: absorption refrigeration vibration heat transfer enhance |
