摘　　要：以单效溴化锂吸收式制冷机为研究对象,对溴化锂水溶液的热力性质参数进行了计算机模拟。通过模拟计算,得到了求解溴化锂水溶液热力参数的较为精确的计算方法。溴化锂吸收式制冷机是以水为制冷剂,溴化锂为吸收剂,通过消耗热能来实现制冷目的的。通过对单效循环的仿真模拟计算,实现了对机组在不同工作工况下的性能预测。为进一步利用数字和模拟手段深入研究溴化锂吸收式制冷机组奠定了良好的基础。A single effect absorption chiller was,in the paper,chosen as the target to be investigated.An accurate method that is used to predict the thermaldynamic parameters of LiBr/water solution would be gotten by the simulation.The Lithium Bromide absorption chiller,consuming heat energy,is a kind of machine that utilizes water as refrigerant and lithium bromide as absorbent.Through simulating the cycle of the single effect absorption refrigerating,the performance of the chiller,such as the cooling capacity,power consumed and COP could be predicted under variable working conditions.It lays a foundation for further investigating the performance of absorption chiller by digital means and simulation.
