摘要
Abstract
For convective heat transfer boundary conditions,a numerical model of a plate counterflow exchanger is established in this paper. Distribution law of Solution temperature and concentration field and air temperature field is analyzed. Then using lithium chloride solution as desiccant,the model is validated by experimental method. The re-sults shows that the deviation of 97%experiment values and calculated values of the dehumidification and regenera-tion efficiency is within 20%,and the average deviation is about 7.8%. The calculation results and experimental results are in good agreement,which means the change rule of heat and mass transfer process is basically reflected by this model.关键词
