摘要:

储热对耦合太阳能辅热的先进绝热压缩空气储能系统有重要影响。为研究系统热力性能随储热特性的变化规律并获得系统最佳热力性能,采用仿真计算的方法,分析系统热力性能随三类换热器效能的变化,并开展多目标优化。结果表明:当第一类换热器效能从0.7增加到0.94时,效率存在最高值为54.85%,而流密度增大6.54%;第二类和第三类换热器效能从0.7增加到0.94时,系统热力性能的变化趋势相同。其中,效率均存在最高值,分别为50.90%和50.98%,流密度也均存在最大值,分别为8.77×106 J/m3和8.78×106 J/m3。可以看出,效率随储热特性的变化规律相同,而流密度的变化规律不同;系统的最优效率和流密度分别为55.729%和9.432×106 J/m3

Abstract: Thermal storage plays an important role in advanced adiabatic compressed air energy storage system coupled with solar heating. To investigate the variation of system's thermodynamic performance with thermal storage characteristics and get system's optimal performance, this paper analyzes the variations of thermodynamic performance with three heat exchanger effectiveness and conducts multi-objective optimization by adopting simulation calculation method. The results show that when first heat exchanger effectiveness increases from 0.7 to 0.94, exergy efficiency exists the highest value, 54.85%, but exergy density augments 6.54%. As second and third heat exchanger effectiveness increase from 0.7 to 0.94, the variation tendencies of thermodynamic performance are the same. Meanwhile, exergy efficiencies exist the highest values, which are respectively 50.90% and 50.98%. Exergy densities have the largest values, which are separately 8.77×106 and 8.78×106 J/m3. It can be seen that the variation of exergy efficiency with thermal storage characteristics is the same, but it is different for exergy density. The optimal exergy efficiency and exergy density of system are respectively 55.729% and 9.432×106 J/m3.
