本文对以LiBr-H2 O为工质对的第二类吸收式热泵即吸收式热变换器 (absorptionheattrans former)的热力循环过程进行了模拟计算。详尽分析研究了循环倍率、稀溶液的浓度、蒸发温度、冷凝温度对系统的性能系数COP、发生温度、吸收温度、工业余热提升温度的影响规律。模拟计算的结果与作者研制开发的工业规模第二类吸收式热泵系统的性能测试数据进行了对比 ,结果表明 ,理论模拟计算的结果同实测的数据吻合较好。所得到的规律性将为这类吸收热泵性能的提高、系统的优化设计与工业开发提供了必要的理论依据
In this paper, the thermodynamic cycle of a second type absorption heat pump, ie absorption heat transfer, with LiBr-H 2 O as working medium pair is simulated. The effects of circulation rate, dilute solution concentration, evaporation temperature and condensation temperature on the COP, temperature, absorption temperature and temperature of industrial waste heat increase were analyzed in detail. The results of the simulation are compared with the performance test data of the industrial absorption heat pump system of the second type developed by the author. The results show that the theoretical simulation results are in good agreement with the measured data. The regularity obtained will provide the necessary theoretical basis for the improvement of the performance of such absorption heat pumps, the optimal design of the system and the industrial development
