| Abstract: | When the temperature of heat source is relatively low,the falling film generator in the lithium bromide absorption machine can improve its heat and mass transfer performance.And how to apply some enhancing surface in the falling film generator to augment the heat and mass transfer outside the tube is what we exactly want to make research.In the paper,the experiment is processed with smooth tube and swirl groove tube in the lithium bromide falling film generator.By analyzing the results of the experiment,we know that the swirl groove tube can enhance its heat and mass transfer. |
