中文摘要：
对新近提出的串联闭链式循环系统（CCLC）进行了模拟计算,讨论了CCLC所利用的变温热源在低温发电方面的性质.并在此基础上,与水蒸汽简单朗肯循环进行了定性和定量的对比,指出CCLC在热回收方面的优势和向有用功转化方面的不足.按照热源和工质性质合理选取参数才能充分利用低温热能的原则,对原CCLC的方案及其压力匹配提出了改进方案,并引进了多功能系统的概念以利用太阳能,得到了更好的效果.图8表6参8
英文摘要：
A simulation calculation of the recently proposed CCLC （cascaded closed loop cycle） system has been performed and the low temperature power generation property of variable heat sources （e. g. gas turbine＇ s exhaust gas）, used in CCLC, is being discussed. Acomparison with a simple steam Rankine cycle shows the advatage of CCLC in respect to recuperation of exergy but also its inadequacy of converting it into useful work. According to the principle, that low temperature heat can be fully utilized only by power choice of the working medium as well as the parameters to match the special features of the heat source, is an improved CCLC cycle configuration is being proposed. Inaddition, a multifunctiona/system concept is introduced for obtaining an even better effcet by making use of solar energy. Figs 8, tables 6 and refs 8.
