【摘要】 本文借鉴吸收式制冷和热泵工作原理,提出了一种新的利用溶液浓差变化的低品位热能直接发电技术。先通过热分离的方法将低品位热能转换成溶液的浓差(化学势)能,然后利用逆向电渗析电池来替代吸收式制冷系统内的蒸发器和吸收器,将溶液浓差能直接转换成电能。所构成的循环可称之为"热-电"转换循环,用以区别常规的"热-功"转换循环。尽管与常规的低品位热能"热-功"转换循环相比,新的"热-电"转换循环具有许多优点,但对其工作性能的研究刚开始,还有许多的研究工作需要进行。更多还原

【Abstract】 Referring to absorption refrigeration and heat pump working principles, a new technology of power generated directly from low-grade thermal energy(LGTE) by solution concentration change is proposed in this paper. The LGTE is first converted into the solution chemical potential energy by the heat separation method, and the potential energy can be directly converted into electricity by reverse electrodialysis(RED) cells which replaces evaporator and absorber in the absorption refrigeration system. The cycle can be called the ‘heat-electricity’ conversion cycle and is completely different from the conventional ‘heat-work’ conversion cycle. Although the new ‘heat-electricity’ conversion cycle has many advantages, the research on its operation performance is just started and there is a lot of research work to be done in the future.更多还原
