摘要
通过对溴化锂吸收式制冷机原理的分析 ,提出了制冷机最大理论热力系数 ,计算表明最大热力系数与溶液浓度和冷热源温度等的关系不大 ,而主要取决于制冷机发生器个数 ,提出了一个评价吸收式制冷机性能的指标———机器效率。
Provides a probable greatest theoretical thermodynamic coefficient of lithium bromide absorption refrigerating machine by an analysis of its working principle. A calculation shows that the coefficient is less related with concentration of the solution and the temperature of cold and heat sources, but mainly related to the number of generators. Gives a criterion, the machine efficiency, for assessing perfromance of the absorption chiller.
