| 为优化设计溴化锂吸收式制冷机，提出了一个多变量多约束的单优化目标函数的优化设计数学模型．采用复合形法求解蒸汽型溴化锂吸收式制冷机的优化设计数学模型，并应用Visual C++语言开发了优化设计软件．利用优化设计软件对一个实际工程算例进行了优化设计，结果表明 通过优化设计，相同制冷量的溴化锂吸收式制冷机在保证较高性能系数的前提下，换热器总的换热面积大大减小，制冷机的综合性能提高，同时提高了机组设计效率，缩短了产品开发周期． |
| 英文摘要: |
| A mathematical model including multi-variables, multi-constraints and single-objective function, is proposed for optimization design of the lithium-bromide absorption refrigerator. The problem of optimization design mathematical model for a steam-heat-lithium-bromide absorption refrigerator was solved by using the complex method, and the corresponding software was developed by using Visual C+〓+. The optimization design for a actual engineering case was carried using the optimization design software. The optimization design result reveals that the comprehensive performance of the lithium-bromide absorption refrigerator can be improved because of greatly reducing total heat exchanger area, while the \%COP\% of the refrigerator does not fall. In addition, the design efficiency of the refrigerator is increased and the design period of a product is shortened. |
