摘要 吸收制冷循环能利用低品位热能,例如太阳能、地热和废热等,具有节能和环保等一系列优点,有着十分宽广的发展前景.然而,传统吸收制冷循环无法获得低的制冷温度,这一缺陷极大地限制了吸收制冷的应用范围.为此,本文研究了一个综合有吸收制冷循环和压缩式自行复叠循环优点的新吸收制冷循环,以期达到利用低品位热能获得低温的目的,该循环采用R23+R134a/DMF工质对.通过新循环数学物理模型的计算表明,在160℃发生温度下,新循环可以获得约-62℃的制冷温度,远低于传统基本吸收制冷循环所能获得的制冷温度.同时,在157℃发生温度下,新吸收制冷系统获得了-47.3℃制冷温度,为吸收制冷循环迄今为止获得的最低制冷温度.理论和实验结果都证明了采用自行复叠原理的新循环能够利用低品位热能获得低的制冷温度.新吸收制冷循环也可以为其他形式热驱动深度制冷方法提供有益的参考.
