热分析法在吸收式制冷机中的应用

由于影响吸收式制冷机的因素很多，针对吸收式制冷机性能评价的复杂性，运用COP分析法、Yong分析法、热经济学分析法对吸收式制冷机性能进行评价，得到三种方法各自的特点，COP分析法是从热力学第一定律对系统进行衡算，Yong分析法是热力学第一定律与热力学第二定律相结合的产物，热经济分析法是经济优化技术与Yong分析法的结合．分析了它们在吸收式制冷机性能优化过程中所起的作用。

Application of thermal analysis for the absorption chiller

The performance of an absorption chiller may be affected by many factors and is therefore difficult to evaluate. In this paper, the methods of COP analysis, exergy analysis and thermo-economic analysis are used respectively to evaluate the performance of an absorption chiller. Features of the three analysis methods are discussed. The evaluation of the chiller performance by the COP analysis method is carried out on the basis of the first law of thermodynamics, yet the same work by the exergy analysis method is done based on the first and second laws of thermodynamics. The thermo-economic analysis is a combination of the exergy analysis and economic optimization.
