Establishment and Research on Theoretical Model of Lithium Bromide Absorption System Based on MATALAB

溴化锂吸收式制冷机组区别于其它形式制冷机组具有明显的优势,是节约电力消耗,降低运行成本的最佳选择。通过对溴化锂机组中各部件换热过程中基本条件的假设,各部件性能参数的控制,经济温差的控制,机组运行过程中避免溴化锂结晶的浓度与温度的控制,建立了溴化锂吸收式机组中各个部件数学模型,并且以双效溴化锂吸收式机组为例给出了计算程序,建立起系统模型,同时给出热水型双效溴化锂吸收式机组的模拟界面,得出不同热源水温度下机组的cop值及制冷量,直观显示了机组不同热源条件下的性能区别,便于从中选出最佳运行方案,为溴化锂吸收式制冷系统的数学模拟和优化分析奠定了基础,也为今后机组改造创新的研究及机组与热电结合的分析也提供了理论依据。

Lithium bromide absorption system has some obvious advantages,it is the best choice for energy saving and reducing operating cost.By Studying on each component unit model of lithium bromide absorption system,this thesis established model with double-effect lithium bromide absorption system,and given the simulation interface and the result of calculation of system using hot water,shown the performance difference between units with different heat source conditions.These provide theoretical basis for future research.
