Theoretical thermodynamic analysis on resorption power generation and pumpless ORC

Resorption power generation cycle (RPGC) has been theoretically investigated and compared with pumpless organic Rankine cycle (PORC). The PORC operates without a liquid pump in conventional ORC and shares the similar configuration with RPGC. Three different organic fluids (pentane, R123 and R245fa) used in PORCs and four different reactant salts (manganese chloride, strontium chloride, barium chloride and sodium bromide) used in RPGCs have been analysed and evaluated in terms of the power generation capacity, thermal efficiency and energy density under the conditions of heat source temperature from 60 °C to 180 °C and heat sink temperature at 30 °C. The RPGCs have been analysed at ideal equilibrium conditions. Resorption power generation system using a pair of two same salts has been studied for the first time.

对吸收式发电循环（RPGC）进行了理论上的研究，并将其与无泵有机朗肯循环（PORC）进行了比较。PORC在传统的有机朗肯循环中无需液体泵，其配置与RPGC相似。对在PORC中使用的三种不同有机流体（戊烷、R123和R245fa）以及在RPGC中使用的四种不同反应盐（氯化锰、氯化锶、氯化钡和溴化钠）进行了分析评估，评估内容包括在60°C至180°C的热源温度和30°C的冷源温度条件下的发电能力、热效率和能量密度。RPGC在理想平衡条件下进行了分析。首次研究了使用一对相同盐类的吸收式发电系统。
