摘　　要：介绍了热管废热溴化锂制冷机的工作原理,讨论了驱动热源温度对机组各个发生器制冷量的影响。在给定的温度区间内通过理论计算和分析,得到了高压发生器、低压发生器a和b的制冷量以及它们与总制冷量的比值分别随着烟气进口、中间和出口温度变化的曲线图。论文中还给出最佳中间温度区间,为今后的实验论证提供了理论依据。In this paper working principle of waste heat LiBr - H2O absorption chiller with heat pipe was introduced anti effect of temperature of driving heat source on refrigerating capacity of every generator of units was discussed. In order to find the curve that cooling capacity of the high pressure generator, the low pressure generator a, b and the ratio of them and the total cool- ing capacity change with the inlet temperature, the middle temperature and the outlet temperature of the gas, the theoretical calculation and the analysis were given in a given temperature range. The optimal intermediate temperature was also given. This can provide theoretical evidence for the future experiment argumentation.
