摘要(Abstract)：

针对废热驱动型双效溴化锂吸收式制冷机组的性能特点,建立了该机组在扰动条件下的数学模型,并编制相应的仿真程序。在将仿真结果与试验数据对比分析有效的基础上,分析了冷水进口温度和流量的变化及其变化快慢对吸收式机组的性能影响,并就其对制冷量与COP的影响进行了敏感性分析。
Focusing on dynamic performance study of waste-driven double-effect LiBr absorption chiller when the parameters of chilled water change.First,the dynamic math model is built and simulation program of this kind of chiller under disturbance process is developed.Then,based on this simulation platform,the influence of inlet temperature and flow rate of chilled water on the performance of absorption chiller is studied.And their sensitivity on the cooling capacity and COP is analyzed.
