溴化锂制冷机能效分析 【英文篇名】 Energy analysis of the lithium bromide absorption refrigerating machine 【作者中文名】 周湘江; 寇广孝; 【作者英文名】 By Zhou Xiangjiang and Kou Guangxiao; 【作者单位】 中南工学院; 【文献出处】 暖通空调, HV 热力系数; 机器效率; 【英文关键词】 lithium bromide absorption refrigerating machine; coefficient of performance; machine efficiency; 【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。 【英文摘要】 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.
