摘要

结合朗肯循环和蒸汽吸收循环,利用制冷功率输出比变化的优势,提出了以氨-水为工质的制冷动力联合循环。研究了低温热源在循环运行中的应用。给出了参数分析的结果,指出了优化的范围。文中还给出了利用遗传算法对不同环境温度下的第二定律效率循环进行热力学优化的结果。该循环在制冷和发电方面显示出良好的潜力。

Combined Cycle for Power Generation and Refrigeration Using Low Temperature Heat Sources
A combined refrigeration and power cycle, which uses ammonia-water as the working fluid, is proposed by combining Rankine and vapour absorption cycles with an advantage of varying refrigeration capacity to power output ratio. The study investigates the usage of low temperature heat sources for the cycle operation. Results of parametric analysis are presented, which show the scope for optimization. Results of thermodynamic optimization of the cycle for second law efficiency performed using genetic algorithm for different ambient temperatures are also presented. The cycle shows good potential for obtaining refrigeration and power generation.
