|
摘要
应用集总参数法建立太阳能集热吸附床能量守恒的数学模型,对以活性炭-甲醇为工质对的真空集热管吸附床和平板式集热吸附床进行模拟分析比较,分析吸附床的逐时吸附速率,得到集热床的温度和时间的函数关系,求解函数并绘制出吸附床温度随时间变化的曲线图。对太阳能吸附式制冷系统进行性能分析,对比分析两种吸附床系统的优缺点,并提出了改进的方向。
Based a mathematical model of solar adsorption bed of energy conservation established with lumped parameter method, the vacuum tube adsorption bed and flat plate adsorption bed with activated carbon-methanol as the working pairs was simulated and compared, and the hourly adsorption rate of adsorption bed was analyzed, and a function of temperature and time of adsorption bed was gotten, and the function and plots of the adsorption bed temperature versus time was solved. Finally, solar adsorption refrigeration system performance was analyzed and the improvement direction was put forward.
