Impact of different chemical additive on the refrigeration potency

In order to improve the refrigeration efficiency of the lithium bromide absorption refrigeration system,surface active agent could be added in the cryogen to improve the heat transfer efficiency in the processes of solution evaporation,absorption and condensation as well.By studying the working principle and process of the lithium bromide absorption refrigeration system,this paper found out the relationship of influence of the active agent on refrigeration efficiency.Based on the relationship,this paper compared the refrigeration performance of three different active agents such as the n-hexanol,alcooln-hexylique and 1-hydroxyhexane.According to the experiment results,it was found that the refrigerant congealment reached its peak with the highest refrigeration efficiency when the concentration of the added n-hexanol and alcooln-hexylique was 150ppm,while the concentration of 1-hydroxyhexane should be 280ppm to achieve the highest refrigeration efficiency.
