溴化锂吸收式制冷机性能的模拟分析

SIMULATION ANALYSIS OF PROPERTY OF LiBr-H_2O ABSORPTION REFRIGERATING MACHINE

本文建立了溴化锂吸收式制冷机的数学模型,并充分考虑了影响传热系数的诸因素,为了提高模拟结果的可信度,并对数学模型进行了实验验证,证明了其应用性。利用有效的数学方法求解数学模型并在计算机上成功地模拟了制冷机在非设计工况下的工作情况,得到了不同影响因素与制冷机性能间的关系。

In this paper,a general mathematical model of refrigerating machine has been built up,in which all kinds of elements that effect heat transfer coefficient are considered.In order to prove simulation results to be convincible further,we make experiment to test mathematical model and gain satisfactory conclusion.At last,we simulate refrigerator operation under non-design points on computer effective mathematic method,and obtain relation between some elements and refrigerator property.
