本文将甲醇化学链燃烧间冷循环和内置CO_2超临界热泵的有机朗肯循环集成,提出了一种新的分布式冷热电多联产系统。以外置热泵循环为参比系统,利用ASPEN Plus对新系统和参比系统进行热力学模拟计算,并通过图像(?)分析方法(EUD分析法)对两系统的关键对比部位进行了(?)损失图像比较。结果表明,新循环的(?)效率和能量利用率分别比参比循环高约4%和20%,同时可以实现动力系统和CO_2分离技术一体化。
In this paper, the integration of organic Rankine cycle with methanol CO loop and the built-in CO_2 supercritical heat pump is presented. A new distributed COHP system is proposed. Using external heat pump cycle as a reference system, ASPEN Plus was used to carry out thermodynamic simulation of the new system and the reference system, and the key comparative sites of the two systems were subjected to (?) Loss through the image analysis method (EUD analysis) Image comparison. The results show that the efficiency and energy efficiency of the new cycle are about 4% and 20% higher than that of the reference cycle, respectively, and the integration of the power system and CO_2 separation technology can be realized at the same time.
