摘　　要：建立了H_2O/LiBr吸收式热变换器数学模型,利用EES(Engineering Equation Solver)软件对非设计工况下的系统热力性能进行了数值模拟,研究了冷却水参数包括冷却水温度和流量变化对系统的温升、制热量、性能系数以及第二定律效率的影响。结果表明,冷却水参数对吸收式热变换器的性能具有很大的影响,合理地设计冷却水参数对提高吸收式热变换器系统的技术经济性具有重要意义。A mathematical model for simulating the off-design performance of an absorption heat transformer （AHT） using H2O/LiBr as working fluids has been built in this paper. With EES （Engineering Equation Solver）, the effects of cooling water parameters, including cooling water temperature and mass flow rate, on the gross temperature lift, heating capacity, coefficient of performance and second law efficiency of the AHT are analyzed. The results show that the cooling water parameters have great influence on the AHT performance, and therefore, the reasonable design of these parameters can improve the technical economy of the AHT.
