中文摘要：
本文提出了一种新型的采用氨水混合工质的动力／制冷复合循环。该循环以中低温工业余热或燃气轮机排气为热源，将动力、制冷子循环采用串联方式连接，基础循环工质为氨质量浓度为0．27的氨水溶液，热源为365℃／104．3kPa的热空气，透平进气参数为350℃／3750kPa，以热效率η1、[火用]效率η2作为评价准则，模拟计算表明本循环的热效率η1为17．8％，[火用]效率η2为45％，通过与其它有代表性的分供系统及联供系统进行热力性能方面的比较，表明本循环η1、η2均有不同程度提高。
英文摘要：
In this paper, a novel ammonia/water absorption power/refrigeration combined cycle is proposed and analyzed. The power sub-cycle and the absorption refrigeration sub-cycle are seriesconnected, driven by available mid or low level heat sources with suitable temperature, such as industrial waste heat or gas turbine exhaust heat. A detailed simulation calculation has been conducted, with both the energy efficiency and the exergy efficiency as the performance indexes. The main parameters of the base case cycle are as the followings： the basic working fluid ammonia mass fraction of 0.27, the parameters of the air chosen as the heat source fluid are 365℃/104.3 kPa, the turbine inlet parameters of 350℃/3750 kPa. The energy efficiency and the exergy efficiency are found to be 17.8% and 45% respectively. A comparison with other cogeneration system and separate generation system in the literatures concluded the thermodynamic performance improvement of the novel combined cycle.
