摘　　要：研究低于１００℃不稳定热源驱动的一种改进吸收制冷循环。以ＮＨ３－ＬＩＮＯ３作为工作介质进行了模拟计算，并对两级和三级循环的计算结果进行了分析。结果表明，改进循环能够在低温不稳定热源（６０℃～１００℃）驱动下稳定的运行，具有较强的变工况适应能力，并且三级吸收循环可以在一４０℃制冷温度下稳定运行。This paper mainly deals with an improved absorption refrigeration cycle withstaged absorption driven by unsteady thermal sources below 100C. Ammonia-Lithium Nitrate(NH3- LiNO3) are selected as the working fluids and the calculation results for the two-stagedcycle and the three-staged cycle are analyzed in detail. It is demonstrated that the improved cycle is able to steadily run when driven by low grade thermal sources as low as 65, and to produce deep refrigeration temperature as low as-40
