| 摘 要： | 比较了水-溴化锂-硝酸锂三元工质与传统的水-溴化锂工质的单、双效吸收式制冷循环，分析了发生温度、冷凝温度和蒸发温度对系统性能的影响；同时也分析了直燃型双效制冷系统。结果表明：采用新工质后，系统的热力系数COP有了明显的提高，其它表征系统热力性能的经济指标也均有不同程度的改善，尤其在直燃型双效冷热水机组中有明显的优势，热力系数COP提高约30％，溶液循环倍率f降低12％。因此，该新工质与传统的水-溴化锂工质相比，具有较好的热力性能。

| Abstract: | The water-lithium bromide-lithium nitrate absorption refrigeration cycle is compared with the traditional water-lithium bromide system.The effect of generating temperature, condensing temperature and evaporating temperature on system performance is analyzed. Moreover, the double-effect absorption refrigeration system is also investigated.The results show that the COP of the water-lithium bromide-lithium nitrate absorption refrigeration system is enhanced and the other thermodynamic parameters are also improved. Especially for the double-effect absorption system,the COP has been increased by 30% and the f has been reduced by 12%.Thus, the water-lithium bromide-lithium nitrate absorption system has better performance than the system of water-lithium bromide. |
